There are two OVA adaptations of Aki Sora, both produced by Hoods Entertainment, with Takeo Takahashi as director, Jukki Hanada as scriptwriter and Kazuya Kuroda as character designer and chief animation director.
Shaft produced a Popotan anime, featuring Shinichiro Kimura's directing and storyboards, Jukki Hanada's writing, Haruka Sakurai's character designs (based on Akio Watanabe's original concept), and Rondo Mizukami's animation oversight.
