Age 26. Sports editor at Weekly JIDAI.

Yumi, one of the four women we actually see working within JIDAI, is almost the complete opposite of Hiroko, if only in their approach to working within a "man's world." Yumi chose to embrace her "womanly" side instead of trying to run with the men. She is engaged to an unnamed man, though there are hints that her fiancé was the former boyfriend of co-worker Maiko Kaji.
