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?

This anime is so cute! I might be biased mainly because I adore cutesy animes, am interested in space exploration, and am a lesbian. But, I think it's a great production nonetheless. It's perfect if you're ever bored during summer or if you don't know what to watch. The plot itself isn't hard to follow and is more of a leisurely watch, the art style is perfect for the overall vibe, the characters are very adorable and have admirable personalities, and it overall just made me very happy to watch. I think if you're looking for light, comedic, and uplifting animes, you'd most certainly enjoy ...

Asteroid in Love: Wait, it’s About Space, Right?

Hello, everyone. I’ve developed a good few interests over the years, various hobbies that I enjoy spending my time with. One of which, I’m doing right now. I think they’re a very important part of life, and I’m sure most of you would agree with that. A lucky few may even turn these passions into careers or turn them into something more viable in their everyday life, but for many, that won’t happen. However, they are still incredibly rewarding experiences and life would certainly be far worse without them. I was never a very passionate person when ...

I'm in love with astronomy, so I searched for an anime that will focus on something like that and I found out about this anime. To begin with, I cannot say I didn't enjoy the anime but there's a lot of things lacking. As astronomy lover, I expected a lot of nice landscapes and space scenes, something like Kimi no Na wa, but that was not the case with this anime.

The plot is interesting, but the story development is obviously not that good. I would say that sound was okay, whereas I was not in love with the art style. I don't know, ...
