From left to right: Ao, Mai, Mari, Mikage and Mira

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 with the aim of fulfilling her promise. A dwindling member count, however, causes the astronomy club to be merged with the earth science club. While disappointed, Mira decides to join the earth science club anyways and finds herself reunited with Ao.

Koisuru Asteriod (恋する小惑星, "Asteroid in Love") is a 4koma manga by Quro and serialised in Manga Time Kirara Carat since 2017. An anime adaptation began airing in January 2020: it is produced by Dogakobo and is available on Website/Crunchyroll for viewing.


Koisuru Asteriod provides examples of:

  • Childhood Friends:
    • While they'd only spent time together briefly as children, Mira and Ao struck up a fast friendship that left a lasting impression on both.
    • Suzu and Mira have also known each other since childhood, to the point where Suzu is fiercely protective of Mira.
  • Club Stub: The Astronomy Club and Geology Clubs saw a decline in members in the previous year, so to save the club, they were merged together. However, with few accomplishments under their belt, their funding remains very limited for club activities, and it members tend to retain their pre-merger identities, calling themselves coming from the "astronomony side" or the "geology side".
  • Embarrassing First Name: Moe Suzuya was not fond of being called "Moe Moe" and asked Mira to call her "Suzu" instead.
  • Japanese School Club: Mira reluctantly joins the Earth Science club after learning that the Astronomy club is to be merged with them from a lack of members.
  • Advertisement:
  • Last-Name Basis: Apart from Mira and Ao, most of the cast go by their last names or nicknames derived from their surnames.
  • Lost in Translation: The club after the merger of Astronomy and Geology clubs is called the Earth Science Club. This is because in the Japanese curriculum, astronomy and geology are classified as earth science subjects. Elsewhere, relating astronomy with the earth sciences would be a head-scratcher.
  • Meaningful Name: Mira is named after a variable red giant star in the constellation Cetus and is Latin for "wonderful", mirroring how Ao sees her.
  • Product Placement: In the second episode, the telescope the Earth Sciences Club uses is rather conspicuously Vixen-branded.
  • Student Council President: Mira's older sister Misa is president of the school's student council. Monroe tries to get Mira to convince Misa to increase their club's budget.
  • Tomboy and Girly Girl: When Mira meets Ao for the first time, she imagines that Ao is a boy owing to her appearance and mannerisms, hence her surprise when reuniting with Ao during high school and discovering that Ao is in fact, a girl.
  • Undisclosed Funds: The club budget for the Earth Science club isn't disclosed, but Mira and Ao are rather disappointed when they see it.
  • Western Zodiac: The second episode has the Earth Science club explore the different zodiac constellations, and the zodiac is also featured in each episode's eye-catches.
