In a fateful childhood encounter, Mira Kinohata met a stargazing dreamer named Ao Manaka. Though their time together was short, Ao showed Mira the wonders of astronomy, from orbiting planets to distant stars. Before they parted, Mira learned that a star with her name exists, but there are none with Ao's. And so, she forged a promise: one day, she would discover a new asteroid and name it after Ao.

Years later, Mira is still fascinated with astronomy. Now in high school at Hoshizaki Academy, she tries to join the Astronomy Club. Unfortunately, she finds out that the club has been merged with the Geology Club to form a single Earth Sciences Club. She joins this new club and finds a pleasant surprise—she reunites with Ao after years of separation.

Alongside their new clubmates, Mira and Ao begin their journey together to fulfill their promise. How hard could it possibly be to find an asteroid?

"Koisuru Asteroid" is one of those anime than unless you're interested on its subject matter you won't be liking it as much as you'd want to. What if I told you that's not always the case. What if I told you that the characters could make the story rather the aforementioned "subject matter"? "Koisuru Asteroid" is certainly one of those anime, and I'll prove it to you.

Yes, because the characters are so likable it makes me ignore the fact i've never been interested in astronomy. It's fascinating because throughout the anime I learned so much about something that it never mattered to me and all ...

Mixed Feelings
Kirara shows for me are occupy one of two states. What this means is they are either some of the best anime I have ever watched (K-On, Yuru Camp, Hidamari Sketch), or incredibly mediocre with nothing better to offer (many many other shows). Koisuru Asteroid is, unfortunately, as boring as they come when it comes to CGDCT. I've had similar experiences with Rifle is Beautiful last season and normally I would have done the sensible thing and stopped watching after a few episodes. And yet somehow I kept pushing myself to watch this, because, similar to Rifle Is Beautiful, this is made by a renowned ...

Life sucks, so let’s just allow ourselves to sink into the soft pillowy embrace of alcoho-er...I mean...cute girl anime.

If its core fanbase wasn’t evidence enough, it’s hard to fuck up a cute girl anime. In the past, I’ve gone on record being fairly lenient towards most low-effort moe anime. With “Koisuru Asteroid”, most of my convictions about cute girl anime have been gravely perturbed.

The term “CGDCT” or “Cute girls doing cute things” is one I’ve never been a fan of, if not for the sole reason that I grew up in the era that encapsulated its inception and persistence. I get the appeal ...
