A 12-episode anime adaptation by Studio Comet and directed by Shinji Takamatsu aired in Japan between July and September 2009.

Sora no Manimani revolves around Saku Ōyagi, a bookworm who moves back to the town he lived in as a child after seven years.

However, this was a misunderstanding since he was too stubborn to listen to the whole story (the fall had put her in the hospital so she could not see him off), and later becomes friends with Mihoshi again after they meet attending the same high school.

Hime Makita, a girl in Saku's class who has a crush on him, also joins the astronomy club.

The manga, written and illustrated by Mami Kashiwabara, was serialized in Kodansha's Monthly Afternoon between the November 2005 and September 2011 issues.
