History Manga / AsteroidInLove

* TreasureMap: Mai's interest in cartography comes from the recreational use of this: treasure maps her elementary-school friend [[spoiler:Keiko]] made for her as simple treasure-hunt games. She became interested in maps as she was fascinated by the experience of exploring with maps, even in places she knows a lot about

--->The light of our wish\\

Let us move in burning passion\\
Like the stars that color the [[TitleDrop night sky]]

* PoseOfSupplication: PlayedForLaughs. Mira prostrates herself towards the hot springs during [[HotSpringEpisode Chapter 6]] after Mikage discusses the potential origins of them, so as to express her gratitude.

* PurelyAestheticGlasses: Mikage uses these to invoke GlassesMeansSmarter when running the Geology club's SchoolFestival exhibit the year before Mira enters.

* RunningAwayToCry: In the manga's NewYearHasCome chapter, it is implied Ao attempts to do this after Mira states her new year's wish being [[GoalInLive finding an asteroid with Ao]]--we don't get to see Ao's face, but she runs away from the shrine with a hand on the chest, being obviously upset from what sounds like a reiteration of their GoalInLife. It's at this point Mai finds the OOCIsSeriousBusiness too hard to ignore. In the anime, this trope is changed to a quiet sigh.

* ScrewTheRulesIHaveConnections: When the rest of the club learns that Mira is the sister of the SchoolCouncilPresident, Monroe attempts to invoke this ask asking Mira if she could lobby for more funding for their ClubStub. This is never followed through, so it's assumed to be averted.

An anime adaptation began airing in January 2020: it is produced by Creator/{{Dogakobo}} and is available on Website/{{Crunchyroll}} for viewing as well as a dub release by Creator/{{Funimation}}.

* ChangingChorus: The ending theme ''Yōzora'' has a different chorus with its second verse.

* TitleDrop: The forty-second chapter's {{eyecatch}} shows Ao sitting a luggage with several stickers, one of which simply says "Asteroid in Love".

* TwoLinesNoWaiting: In the anime, the Ishigaki arc is structured as this. On one hand, Mira [[spoiler:and Ao]] participate at the Shiny Star Challenge on Ishigaki island, while the rest of the Earth Science Club plus its alumni go to the club's annual summer camp, this time also at Tsukuba.

** There are several times when the [[{{Tsundere}} usually prickly Mikage shows her caring side]], especially when she takes note of her kouhai's achievements. Mira often [[LampshadedTrope takes note of this]], at which point Mikage turns back goes back to her usual mode.

* WideEyesAndShrunkenIrises: In the first chapter of the manga, Ao gets this when the other new member says she wants to find an asteroid. Downplayed when it is adapted in the first episode of the anime, when her irises only shrink a little when that other member's companion calls her "Mira".

* WithAFootOnTheBus: The third segment of Episode 8 and the first segment of episode 9. This mini-arc started with [[spoiler:Ao]] declares she will have to move away at the end of the school year because of her father's transfer. The Earth Sciences and Newspaper clubs having an emergency meeting in an attempt to minimize its impact on [[spoiler:[[HeterosexualLifePartners Mira and Ao]]]]. Mira's CoolBigSis Misa offers staying in her room when she's off for college, [[spoiler:Ao, [[ShyBlueHairedGirl who has trouble speaking up]]]], persuades her mother to let herself to stay in town according to Misa's offer, which is accepted.
* WriteWhatYouKnow: InUniverse. Mira based the {{Love interest}}s in her romantic manga on Ao, of which she mistook for a boy for years and thus has a crush on "him", at least until the UnsettlingGenderReveal when they reunited.

* PhotoMememto: In the thirtieth chapter (animated in the ninth episode), the [[ClubStub Earth Sciences Club]] takes [[https://imgur.com/qbkjASU a picture]] outside of their clubroom, on Mikage and Mari's {{last day of school|plot}}.

* AlphabeticalThemeNaming: This is often the case of FamilyThemeNaming in this series.

* RomanticTwoGirlFriendship: Mira and Ao are extremely close since they reunited, something fully recognized by their schoolmates that the most dramatic moments of the series to date is [[spoiler:Ao's impending move away from the town]] in Chapter 27/Episode 8. The fact that Mira mistook Ao for a boy for years and had a crush on "him", and the tendency for her to call joint outings "dates" cemented the "romantic" part.

* MistakenForFlirting: Moe mistakes Misa's holding Ao's jaw and looking into her face for Misa flirting at Ao. Since Moe has a crush on Misa, this causes her to Dramatic Drop items on her as she seethes in jealousy. Doubles as Moe's Queer Establishing Moment.
* MistakenForRomance: In the seventh chapter, adapted as the first part of the third episode, Misa gets really close to Ao, just to check the latter's closeness towards Mira is something she does towards all people, or just to one person. However, when Moe sees that, she thinks Misa is seducing Ao. Since Moe has a crush on Misa, the former gets enraged with jealousy until Misa explained that Ao was just her guinea pig.

** In the [[Stargazingscene fifth chapter]], Ao mentions the asteroid Vesta. Mira somewhat immediately switched to a "Western-style" school uniform with a vest (Hoshizaki uses SailorFuku) and asks whether Ao means a vest.

* FoodAsABribe: Moe may have accidentally invoked this during the SchoolFestival if Mira didn't stop her in a part of the twenty-first chapter that isn't animated. Specifically, when her crush Misa the StudentCouncilPresident visits the Earth Sciences Club's booth as a panelist of the booth food contest, Moe is seen making half a dozen pancakes to impress Misa. Mira reminds Moe she'd get disqualified if she bribes the panelists, and eventually, Moe serves Misa a single pancake, like any other customer.

->'''Mira Kinohata''': How cool! I never knew I share a name with a star! What about you, Ao? Is there a star with your name?

When she was camping as a child, Mira Kinohata meets Ao Manaka, who points out the existence of a star in the sky named after her. However, Mira becomes saddened to learn that there are no stars named Ao. The two would promise to explore the heavens and eventually get a star named after Ao. Years later, Mira enrolls at Hoshizaki High School and decides to join the astronomy club to fulfill her promise. A dwindling member count, however, causes the astronomy club to be merged with the Earth Sciences Club. While disappointed, Mira decides to join the Earth Sciences Club anyways and finds herself reunited with Ao.

* AndKnowingIsHalfTheBattle: At the end of the TV broadcast of every episode, there's a small segment titled ''Kira Kira Special Issue'' which more fully discusses certain astronomy/geology knowledge points mentioned in that episode. For example, the one for the first episode involves Mira Kinohata discusses Mira, the variable star in Cetus.

* DontCelebrateJustYet: In a part of the ninth episode adapted from the twenty-ninth chapter, Mira starts putting welcoming banners around her house when she hears from her mother that [[spoiler:Ao's mother is willing to consider the plan for Ao to live in the Kinohata residence, and will discuss with her husband]]. Misa has to remind Mira that it's hardly a done deal.

** The names of the Kinohata siblings are just one consonant apart.

* FoolishSiblingResponsibleSibling: Mira and Misa Kinohata follow this dynamic. Mira is an energetic GenkiGirl who is known to be [[TheDitz not particularly intelligent]], while Misa is a composed CoolBigSis who has a TeenGenius reputation.

* PutOnABus: After Misa moves out of the Kinohata residence in Chapter 31, she only appeared twice, both briefly, as of the time of writing (February 2021, at Chapter 47)--once in an anime-original scene of her having a video-chat with Mira, and the other in Chapter 42 when she is shown coming back to the Kinihata residence for vacation, but the focus of that chapter is Ao, who leaves for seeing her parents.

* TechnicolorEyes: The Kinohata family purple-and-gold eyes, vaguely reminiscent of a sun in space.
