IMPORTANT: We are fixing the release of recent episodes. This may take some time unfortunately. At the same time we have hired a dev for new features like: View episodes inside Animension and not third-party sources, OP and ED skipping, Auto-Next episode, MAL syncronization and a dedicated mobile app. As the website continues to run ad-free all of these costs come out of our pocket. If you have any disposable income that you are able to donate, you can do so to the BTC address below. The funds will be used to add features and improve our response time when things break. This message will be removed when the recent releases get fixed.
When she was little, Mira Kinohata met a boy named Ao at a campsite in town. While gazing at the starry sky together, Mira learns that there's a star with the same name as herself, but no star named Ao. The two then promised to one day explore asteroids together and find a star to name it after him.
Several years later, Mira enrolls at the Hoshizaki high school and decides to join the astronomy club to fulfill her promise. However, she learns that the astronomy club will be merged with the geological research society to form the earth science club. Reluctantly, Mira goes to the club room and is reunited with Ao Manaka—the person she made the promise to explore asteroids with—and is shocked to learn that she is a girl!
