Oshigoto Biyori

For some reason, Komachi, an idol-otaku, has just debuted as an idol herself! She forms a group with Sora (anime-otaku) and Yuzuha (doujin author), but everyone's a beginner and an otaku!? Later on, Ayame (game-otaku) and Naru (otaku??) also join members, and things get really lively!
