'Yumi Ochiai' (Japanese: 落合ユミ, Hepburn: 'Ochiai Yumi') is a fictional character in The Drillimation Series of anime and video games, making her debut in Chuhou Joutai. She is the youngest member of the Ochiai Clan, where she serves as the mikohime of the clan. She is also the younger sister of Kagami Ochiai and the youngest child of Hideo Ochiai and Kisumi Torisawa.

Concept and creation

The idea for having Kagami Ochiai a younger sister came naturally, as the real Kagami Ochiai had a younger sister named Yumi. Yumi is a common feminine given name, and it is common for girls' names in Japan to end with the suffix -mi, which means "beauty".

Unlike Kagami, Yumi's hair color wasn't chosen through process of elimination. Instead, it was Kagami Ochiai's suggestion to make it sky blue. Takajima felt this would be perfect for Yumi, and followed suit. Yumi's primary outfit was also chosen by Kagami herself. Takajima also went a step up by making Yumi a shrine maiden, due to her mikohime status.
