Their Promise: Koisuru Asteroid First Episode Impressions and Review

“I became an astronomer not to access the facts about the sky but to see and feel its majesty.” –David Levy

When she was camping as a child, Mira Konohata encountered Ao Manaka, who was stargazing. Thinking Ao to be a boy, Mira made a promise with her new friend: to eventually have a star named after Ao. Some years later, Mira enters high school and resolves to join the astronomy club so that she can fulfil her promise to Ao. However, thanks to dwindling numbers, the astronomy club and geology clubs were on the verge of being disbanded, and thus, were merged to form the Earth Sciences club. Mira meets club president Mari Morino, vice president Mikage Sakurai and senior Mai Inose, as well as a certain blue-haired girl – it turns out that Ao is attending the same school as Mira, and in the time that has passed, had not forgotten their promise. However, with the time that has passed, it’s an awkward reunion, with Mira and Ao struggling to find words to talk to one another. When Ao speaks with Moe, Mira’s childhood friend, she and Mira would go on to have a lengthy, enjoyable catching up under the stars. Later, when Mikage explains that the club’s limited activity resulted in a smaller budget, Mai suggests that the club starts by writing a newsletter to raise awareness of their activities and exploring some of the things they’re interested in. The girls come up with a name for their newsletter later that evening. Koisuru Asteroid (Asteroid in Love) is a four-panel manga serialised in Manga Time Kirara Carat and has been running since 2017. An anime adaptation was announced earlier last year, and as of now, holds the unique distinction of being the new decade’s first slice-of-life anime, as well as being the first Manga Time Kirara adaptation. Koisuru Asteroid (Asteroid in Love) thus has some large expectations to fulfil, but after one episode, the series is off to a solid start.

Out of the gates, Koisuru Asteroid has Mira establish her long term objective: the lofty goal of discovering a star and having it named after Ao. However, even the scaled-back goal of finding a new asteroid is a bit ambitious. Mira herself is named after Omicron Ceti, a variable red giant in the constellation Cetus, a sea monster. This red giant was the first variable star (a star whose magnitude, or brightness, fluctuates noticeably) to be discovered and has a regular period. Mira is also Latin for “wonderful”, which fits Mira’s bright and cheerful personality: befitting of a lead character in a Manga Time Kirara Work, Mira is optimistic, outgoing and driven, having spent the past few years catching up on astronomy so that she could help Ao fulfil their promise. Between Mira and Ao, the determination and excitement is certainly present, although at present, the Earth Sciences Club does have problems of its own: the discovery of asteroids is typically done by satellites equipped with sophisticated CCD chips, and it should be clear that the Earth Sciences Club is unlikely to have either the time or resources to commit towards anything approaching the Lincoln Near-Earth Asteroid Research (LINEAR) or Near-Earth Asteroid Tracking (NEAT) programmes: LINEAR has already found upwards of 147132 objects, of which 19266 have been classified as near-Earth objects. To expect professional tools and techniques in something like Koisuru Asteroid is to be unreasonable, and so, as the series continues, one would expect the Earth Sciences Club to focus on first righting the club, and then acquiring the basic equipment, like a good refractor telescope (these are suited for observing the planets because they have a right-side-up image and reach thermal stability quickly). The journey towards finding an asteroid to name after Ao would therefore be presented as a gentle and fun one as Mira and Ao grows closer together during their time in the Earth Sciences Club, being as much about friendship as much as it is about the astronomy.

Screenshots and Commentary

  • When Mira and Ao meet, Mira’s on a camping trip with family and notices Ao staring up into the stars. Ao passes Mira her binoculars, likely a 7×21. These numbers are commonly used to describe two critical attributes about binoculars, and the first value is the magnification. The second value is the size of the objective lens in millimetres, which determines how much light enters the binoculars. Thus, a 7×21 pair of binoculars would have a magnification of 7x and an objective lens that’s 21 mm across. For astronomy, 7×35 is the most commonly used binocular type, and I run with a pair of Bushnell 10x50s.

  • The fateful meeting has Mira learn of a star that she shares her name with, and speaking volumes to her personality, she immediately resolves to rectify the fact that there are no stars named Ao. This moment sets in motion the remainder of Koisuru Asteroid. Discussion on the series is presently limited, and most folks have taken to the potential yuri driven aspects of Koisuru Asteroid over the astronomy in what little talk that I have been able to find.

  • On the first day of high school, Mira has her heart set on joining the Astronomy Club, but is devastated to learn that what had existed previously no longer is present: Mira’s love for astronomy is such that during this high school’s previous culture festival, she’d visited the Astronomy Club and was hyped up about joining. This turn of events is par the course for many club-oriented slice-of-life series, and the rationale for using this as a plot point is that it forces characters to get creative, in turn helping them get closer to one another.

  • Upon hearing Mira’s desire to join the astronomy club, instructor Yuki Endō takes Mira and Moe to the club room. It’s a bit of a walk to the clubroom, which is located in an older part of campus. Yuki happens to be the Earth Science club’s advisor, and out of the gates, she seems reliable enough: such advisors are actually a bit rare in anime, and in most series of this type, the advisor’s lack of motivation, laziness and other eccentricities are usually deliberate to encourage comedy. By having Yuki be more mature and dependable, it would suggest to viewers that they needn’t worry about the club’s logistics, leaving them free to focus on the students.

  • At the clubroom, Mira and Moe meet the Earth Sciences club’s members for the first time: this club is helmed by president Mari, who was the president of the former Astronomy Club, She’s accompanied by Mikage, who is the vice president and is the most senior member of the former geology club, and Mai, who had previously been a former geology club member. Mikage is initially pleased; as a member of the former geology club, she’s very much into rocks and minerals and worries that the astronomy club will displace any geology-related activities.

  • When Mira explains her reason for joining the astronomy club, that she’s here to fulfil a promise to someone important to her, she learns that the Ao she’d met long ago is in fact the same Ao who’s now present. It’s a bit of an awkward reunion for the two; fate has brought the two together, marking the start of a new journey that will form the bulk of Koisuru Asteroid‘s story. The outcomes might be easy to estimate, but what matters most is the journey.

  • Having now been reunited with Mira, Ao begins to dig out her old astronomy books. My old astronomy books are now more than twenty years old: I bought them after developing a nascent interest in the night sky from reading library books and wanted guides to astronomy of my own. I was nine at the time, and after picking up a pair of 10×25 binoculars, I began exploring the night sky using Terence Dickinson’s Nightwatch. Through the book’s star charts and tips for binocular astronomers, I capitalised on these new binoculars to look at the moon and nebulae. While my edition is now somewhat dated, being over twenty years old, the tips and tricks in the book remain relevant and useful.

  • I ended up picking up The Backyard Astronomer’s Guide (Terence Dickinson and Alan Dyers) a few years later, which helped me to explore more advanced techniques for binocular astronomy and also appreciate what’s known as naked eye astronomy: there are many astronomical events that don’t require any more equipment than our own eyes to enjoy. Koisuru Asteroid has yet to delve to far into this, so beyond introducing the books, I won’t go too much into details until the anime explores them. For the first episode, audiences are instead treated to character establishment, and when Moe balances a paper bag on Mira’s head, I’m reminded of videos where an owner puts a small object on their pet’s head to gently tease them.

  • After a failed evening where neither Ao or Mira were able to talk to one another via messaging, Mira and Ao attempt to apologise for their seemingly incompatible messaging styles. For me, I am rather similar to Ao in style when it comes to online communication, preferring to use complete sentences and proper grammar unless I am speaking with someone I am very familiar with. In that case, I then devolve into leet-speak and deliberate misspellings. Mira, on the other hand, uses a very casual and relaxed style in her online communications.

  • Moe previously remarks that she likes to make trouble for anyone who gets too close to Mira, but she has no problems with someone like Ao befriending Mira. Mira views Ao as a very mature, composed individual, feeling herself to lack grace. Seconds later, the egg falls from her sandwich, and she rushes off to clean up, leaving Ao alone with Moe. It is here that Ao reveals that her composure is probably an illusion, and that she is in fact, very shy about her choice of words.

  • Moe reassures Ao to be herself and that the dream she shares with Mira will eventually allow the gap between her and Mira to be closed. I was particularly fond of this rooftop scene here, as it gives Moe and Ao time to speak away from the hustle and bustle of the classroom. In addition, the vastness of the sky and its deep blue hue acts as a very subtle metaphor: it creates a feeling of new possibility and hope.

  • Later that evening, Ao picks up her phone and decides to call Mira. Verbal conversations are different than textual ones, with cues like tonal shifts and speed of speech having a major impact on how words and phrases are interpreted. After a slower start, Ao hits her stride when she begins talking about planet-gazing. Mira’s spent the past several years catching up and getting acquainted with astronomy, so by this point in time, she’s got the basics down and is able to keep the conversation with Ao going.

  • This is the part where I get to break out my background as an amateur astronomer: the brightest object visible in this screenshot is Mercury, which is often counted a moderate challenge to sight. Appearing only around 28° from the sun and at its brightest at 10° to 15° above the horizon, Mercury has an estimated apparent magnitude of anywhere from -2.48 to +7.25. The apparent magnitude describes how bright something is to the naked eye, and measurements can vary wildly amongst even individuals.

  • Being a Manga Time Kirara work, Koisuru Asteroid may potentially see discussions split into two distinct buckets; there are those who seek to discuss the story and character dynamics, while others will be driven towards the technical details. I will be doing both, of course: for instance, Ao characterises Mercury as being -4, which would peg it as being equivalent to Venus in brightness. By comparison, a full moon is -13, and the naked eye limit is around +6 to +7. Since Mercury’s apparent magnitude is -2.48 at brightest, one might wonder if Ao’s missing something basic here, but I note that naked eye magnitudes can very widely between individuals, so Ao’s observation isn’t an error.

  • On first glance, Koisuru Asteroid does not seem to be a series that stands apart from others in its direction, themes and even characters. Consequently, discussion elsewhere looks very limited on this series. However, the presence of astronomy, coupled with my own background and experience in amateur astronomy, means that I am confident in saying that I could offer some interesting discussions and provide interesting tidbits on amateur astronomy that could liven things up to a reasonable extent.

  • The Earth Science club’s first activity as a club is to determine how to mitigate the issues that plagued the previous year’s astronomy and geology clubs. The latter had been shafted at the culture festival from a lack of interest, while the former resorted to below-the-belt tactics to draw people in. Mai decides that one way to kick-start things is with a newsletter, which would allow the Earth Science club to increase their visibility and show their fellow students what the club does in their activities. Topics for articles are actually easy to come by, although the girls struggle to come up with a suitable name for their newsletter.

  • Towards the end of the first episode, we have a fantastic moment of all the characters heading off to a restaurant after a long day’s worth of classes and club activities. From left to right, we have Mai, Mikage, Mira, Ao and Mari: only an episode in, I’ve already learnt the names of all the critical players. I’m greatly looking forwards to seeing where Koisuru Asteroid is headed, and I imagine that it will lean more towards the character development side rather than the technical details of astronomy. To be honest, this suits me just fine: while it will be fun to make occasional mention of astronomy and its intricacies to keep my posts fresh, my goal for anime, first and foremost, is to enjoy and appreciate the journey characters go through.

  • Over burgers, the club agrees on a publication name for their newsletter: Kirakira (Sparkle). Ao chose the name, and since both the stars and minerals glitter, it is a fitting one that everyone takes to. I note here that some may think me hypocritical to say that I abhor mention of technical details in relaxing slice-of-life series like Koisuru Asteroid, and then proceed to mention those exact things in my post. I clarify that my intention is to keep my posts refreshing to read, and inclusion of things like binocular aperture properties, or what apparent magnitude is, is so that readers can come away having gained new knowledge.

  • Mikage, being a former geology club member, is determined to make Mira, Ao and Mari see the worth of geology: she greatly resembles Anima Yell!‘s Hanawa Ushiku in mannerisms and appearance. She’s very focused on her club activities, and knowing this means that the Earth Science club can be assured of some progress through the series’ run. With the first episode in the books, I’ve immediately taken a liking to all of the characters, so what Koisuru Asteroid‘s focus will be in the future will be how the Earth Science club’s members get closer to one another and what they gain from their time together. Instructor Yuki already has planned a barbeque for the upcoming weekend, foreshadowing a booked schedule for Mira and the others.

  • As the day draws to a close, Mira and Ao share another conversation together, with Mira expressing gratitude for being able to stargaze and talk again in the present. Ao is gazing out at Orion, one of the most famous and brightest constellations in the sky. With its distinct “belt” of three stars, Mintaka (leftmost, a binary star), Alnilam (blue supergiant) and Alnitak (rightmost, in a triple star system), it is immediately recognisable in the skies and is visible between the late autumn and late winter months in the northern hemisphere. This brings my first anime-related post for 2020 to a close. The new anime season is off to a solid start; besides Koisuru Asteroid, I’m also going to be following and writing about Magia Record and Heya Camp△.

While Koisuru Asteroid is a Manga Time Kirara adaptation and therefore, will share thematic elements and messages similar to other series of its lineage, the focus on amateur astronomy means that this anime is one I’ve immediately taken a liking to. There’s a bit of a personal story behind this, and it may perhaps be a surprise when I say that I’m an amateur astronomer myself. My journey began when I was eight; I got Terence Dickinson’s Skywatch, a beginner’s guide to amateur astronomy, along with a pair of 10×25 binoculars for my birthday, and I still remember pointing those binoculars at the moon for the first time, marvelling at the maria and other lunar features on the moon in hitherto unseen detail. Since then, I’ve made use of binoculars as my workhorse to stargazed to find planets, famous constellations, and nebula in the night skies. I’ve also seen aurora, many total lunar eclipses, a handful of meteor showers (and even a fireball) and a pair of partial solar eclipses. My love for stargazing and astronomy comes from the fact that the hobby is relatively straightforward at the entry-level, and that the stars in the night skies really drives home how vast the universe is. As such, with amateur astronomy being something I still partake in from time to time, Koisuru Asteroid offers a place to both see a fictionalised portrayal of astronomy and its joys that I’m curious to see. Because of the presence of astronomy in Koisuru Asteroid, I presently have plans to write about it at quarterly intervals for the remainder of the season, so that I can continue to offer readers both my thoughts on the anime, as well as provide enjoyable (and useful) information about amateur astronomy and my experiences with stargazing. In particular, I look forwards to seeing how the journey of exploring the night skies to fulfil a long-standing promise will bring Mira and Ao together.

    I’ve been looking forward to this show, both out of professional interest (I write books for middle-school kids that incorporate math and science), and out of my ongoing amazement that the Japanese actually have TV shows like this. Haven’t been able to catch the first episode yet, but it’s in my plans for this evening.

    There are fairly low-tech ways to look for asteroids. I wonder if there might even be computer software commonly available that would function as a “blink comparator,” scanning pics of the same place in the sky from different times and looking for something that moves. If the girls have stated they want to find an asteroid, it’s reasonable to assume that sooner or later they will find an asteroid. That’s storytelling 101.


    • infinitezenith January 4, 2020 at 17:34

      There are certainly more accessible methods for the amateur astronomer to discover asteroids: a proper CCD-equipped telescope, software like Guide Star Catalog to help with measurements and identifications, and proficiency with the techniques mean that it’s definitely a feasible goal. Finding known objects to test the equipment and techniques is one thing, but finding an entirely new object will require patience. The joys of Koisuru Asteriod will then lie in how the girls go about starting, and what they experience en route to their end goal.

      It’s exciting to have a professional author swing by and offer feedback: thank you very much! I do hope you’ll have a chance to give this series a go. It’s a little slow now, but it will be interesting to both see what happens in upcoming episodes, as well as hear your thoughts on things 🙂

    (This is the first time I posted anything on WordPress in any capacity, so bear with me if there are any formatting errors; especially I’m not sure whether this theme supports HTML tags.)

    I have to admit, I made a grave mistake when I watched the first episode of Koisuru Asteroid: I skipped through the first half of the episode so much that I couldn’t comprehend the third segment, let alone enjoying it. I was only floored by this episode when I re-watched it in early February; the main reason being… this doesn’t feel like an average Kirara show.

    I agree with Infinite for most comments for this series, so I’m not going to repeat things he already wrote unless there are factual errors. Also, Koisuru Asteroid is as close to my first brush with astronomy and/or geology as it can be, so I will emphasize character dynamics and personal experiences.

    The segment titles below are my own.

    Segment 1: Promise and Reunion (Adopted from Chapter 1)

    We were first introduced to how the story began: that fateful meeting between Mira and Ao that begins the story. I stand by Infinite’s assessment on Mira there, so I’d give my comments on Ao in this scene. While Mira later describes Ao as being more talkative at the time, there’s something from Ao that never changes. At this age, she’s already using big words (to her knowledge level) when she introduces astronomy to Mira. There is another persisting feature of the dynamic between them in this scene: Ao impresses Mira with her intelligence; Mira impresses Ao with her energy.

    I wonder how old were the two at this scene? I guess the third grade, give or take.

    As to the second half of the segment, I will only note two things. First, Earth Science is taken seriously in the Japanese curriculum; up to middle school, it has equal weight as Physics, Chemistry, and Biology. Second, Mira’s friendly nature is again shown here–when she immediately holds the hand of the blue-haired girl sitting next to her, before even knowing who she is. I will discuss the club’s own problems when I move on to the third segment.

    Manga-Anime divergence: In the manga, the flashback is part of the story Mira tells in the clubroom. I personally like the anime’s re-arrangement.

    Segment 2: Breaking the Ice (Adopted from Chapter 2)

    There’s no doubt Mira and Ao’s reunion is extremely awkward; the first thing about the reunion is Mira found herself having mistaken Ao as a boy for all these years, and the second being they don’t even know how the other side communicates. Ao is caught off guard by Mira’s girly and emoticon-y stream of texts, and the Ao’s terse, formal message that she gets from a book about business emails (Yes, the book Ao borrows from her mom Shiori is actually a book on business emails.) makes Mira suspect Ao doesn’t like her anymore. They could have been going on that way if not for Moe, who worked to break the ice between the two–by encouraging both to speak up more.

    This is why I always see this segment as just a little bit less important to the story compared to the promise itself. It’s hard to keep their promise if they keep on having such an awkward relationship.

    At this point, Mira’s communication style should be obvious to the viewer. It turns out Ao’s is completely the opposite of Mira’s; she doesn’t feel comfortable speaking at all.

    When I watched Ao describing her problems, I was confused about what Ao means when she says she has a problem speaking. On one hand, she mentioned past trauma from being teased for using the wrong word, which means she has a fear of speaking. On the other hand, however, she also says she keeps “panicking at [her] lack of words,” which is more akin to the problem I have–my cognitive processing is faster than I process words, which means I often fall into a “lack of words” situation.

    The result is the same: she has little confidence in speaking. (I prefer Funimation translating it as “I have trouble speaking up” since it focuses on the results) Moe needs to reassure Ao that any awkwardness between she and Mira is more likely to iron out, as long as they actually speak to each other.

    Which comes to the next scene, when Ao calls Mira to explain what she actually feels about Mira and what she feels about their promise. Mira, however, changed the topic to stargazing, which works wonders to their relationship–finally, they can speak normally for once, and, most importantly, not only they remembered their promise, they’re both moving forward to it. And we get to see it the next day; Mira and Ao act exactly the same for the first time since they reunited.

    Ice is broken.

    Segment 3: Integrating a Divided Club (Adopted from Chapter 3)

    My review of the previous segments is dedicated to Ao/Mira dynamics and skipped all the awkwardness about the Earth Sciences Club. I am discussing it further here.

    The situation facing the Earth Science Club is something I’ve seen more in the corporate world rather than in a school setting, fictional or not: post-merger integration between organizations. Two organizations with different cultures, both seeking bigger representation in the merged organization (or at least equal representation) to the point of the two halves compete in recruitment… The first time I read about it is not in Koisuru Asteroid but in Wikipedia. Dai-ichi Kangyo Bank (a predecessor to the Mizuho Financial Group) has this exact problem for three decades, to the point of having two separate HR departments.

    And this is the state of affairs of the Earth Sciences Club when Mira and Ao joins. The two clubs merged only because they correspond to the same school subject. Otherwise, they can’t be more different–the routine activities of the two clubs are totally different, and their leaders’ management styles clash. Mikage Sakurai from Geology is a no-nonsense person who insists an academic club should be purely academic, while Mari Morino from Astronomy has a more laid-back personality who isn’t above using rather underhanded tactics to get visibility. At this point, the Earth Sciences Club is more like two rivaling clubs sharing one clubroom and one Cultural Festival booth; at the time Mira enters the clubroom there’s a virtual wall between the two sides.

    This is obvious to any outsider. I wasn’t surprised when both Mira and Ao see the same issue and proposed the same solution of having consistent joint activities–no telepathy involved here. I would say Mai’s proposal of a newsletter is proper–it keeps face for both groups, it increases visibility, and it forces the members to work together. Eventually, they did one extra thing to further this integration process, but that’s for a different review.

    This segment has the first character development (of many) in this series: Mikage seems to understand the importance of science communication. The scene that comes after also gives one fact–her prickly side is actually… awkwardness.

    Bottom line: The first two segments primed me for something… I didn’t quite expect. Quro plans to tell a story using slices of life, rather than setting up a Slice-of-Life premise, and all will not be smooth sailing. This is the second non-Forward Kirara series I noticed this, after Machikado Mazoku. For MachiMazo, however, it took me 4 episodes to recognize this, nearly causing me to drop it.

      Welcome! Your tagging looks good from here. This is a short reference for common tags WordPress comments support: <b></b> to bold, <em></em> or <i></i> to italicise, <a href=””></a> to do URLs. If you need to quote: <blockquote></blockquote>. I think you have the tags down solid, but if you ever need me to apply any formatting edits or whatnot, I will be happy to apply the changes: just let me know!

      What you experienced in the first episode is precisely why I don’t skip through episodes – earlier scenes often provide important context for what comes next, and in order to have the best enjoyment possible, it is necessary to watch things front-to-back. I also should note that, having run this blog for almost nine years (and having written about anime to some capacity for thirteen), I do my utmost to ensure factual accuracy for readers, and because I do have a relatively functional knowledge of both astronomy and the earth sciences, rest assured the odds of errors here are very slim and we can discuss the other aspect of Koisuru Asteroid without that being a concern 🙂

      On the original promise with Mira and Ao’s meeting, the anime’s approach worked for the medium because it immediately established what the promise was. Right out of the gates, we know what Ao and Mira are about, and this creates that connection between the two. I think the anime’s choice to do things this way was to make it very clear that the promise was going to happen for sure, whereas the manga is going for a different message.

      Incidentally, on the formal communication that Ao falls on, the reason is because she’s tied to picking her words carefully as a result of that little incident. I wouldn’t quite go so far it’s trauma, since she can communicate, it’s more that she’s worried about making mistakes in picking her words. It makes sense for Ao to lack the words, since she’s used to following a script, and Mira’s very much about improvising in the moment. For folks like us, then, the trick is to use that comfort in quickly scripting up something before saying anything: I think ahead of what I want to say, and then say that, which helps me to keep up in a conversation, and this is something Ao doubtlessly improves upon as Koisuru Asteroid continues.

      Finally, on the club’s mergers, I do not believe that the specifics behind it is as complex as any corporation; they are, after all, school clubs, and if memory serves, nothing I, or any of my friends, experienced in high school was ever that intricate. The point of the merger is motivated entirely by the need to create a divide for the sake of the theme surrounding interdisciplinary collaboration: had Mira and Ao joined a pure astronomy club, the opportunity for learning and discovery would be much more limited. The choice to do a newsletter further accentuates that the first step to this collaboration. Much as how Ao and Mira needed to overcome their initial communication barrier, the club must also overcome the different styles between the geological sciences and astronomy sides.

      Koisuru Asteroid is a story about learning that stands out from the other Manga Time Kirara Series because of its emphasis on communication and the sciences; while retaining the same elements that characterise other series, it is able to portray something more mature and meaningful. I feel that Machikado Mazukou, on the other hand, felt like it was spending a bit of time establishing old conventions in the first few episodes because we don’t relate to it quite as strongly. There was a good reason for it, though, and this is why with Kirara series, I’ve opted not to pass any judgment on a series until the entire series has concluded. I look forwards hearing your thoughts on the other episodes: if I may be so blunt, discussions have been very limited out there on Koisuru Asteroid, and outside of AnimeSuki, I don’t think I’ve seen anyone talk about Koisuru Asteroid in quite as insightful a manner.

    I dropped Koisuru Asteroid because I felt it didn’t live up to the view of Orion that’s in your last screenshot. As far as I remember, that’s the first accurate portrayal of a real constellation I’ve seen in anime. Your essay encourages me to re-watch it, in my suddenly copious spare time. Thanks.


    • infinitezenith May 26, 2020 at 14:48

      It’s ultimately your call as to whether or not Koisuru Asteroid is worth your time: I came in for the relaxation and found myself impressed with the educational piece of the series, which is gently woven into what I found to be an engaging story. If you do give the series a go, I would say that the science of Koisuru Asteroid is what made it work 🙂
