Toshishita Joushi no Utamaro-sama Dekkai Kare wo Uketomemasu!!

Airi Mamiya is a hard worker, cleaning up mess after mess of the previous section chief. She's expecting to be promoted now that the section chief is gone but the position is taken by newcomer and younger Kanata Kuzumi. While irritated at first, Airi starts to understand Kanata as they work closely together. But Kanata has a problem, his "utamaro" to be specific. Good thing, Airi has something special of her own.
