Yumiko Shiozai Kabuto

Yumiko Shiozai Kabuto was the wife of Juzo Kabuto in the manga by Gosaku Ōta.

Appearance
Yumiko was only seen in a flashback as an attractive young woman with short dark hair with a small ribbon and an average build.

Personality
Yumiko was friendly, polite, and sweet even to people that others tried to avoid like the younger Dr. Hell. She also admired Hell for his hard work and abilities as a scientist. This caused Hell to become infatuated with her, but Yumiko stayed loyal to Juzo especially after Hell tried to kill him out of hate.

History
Yumiko Shiozai at some point met Juzo and they started dating and later got engaged. In college, they studied abroad in Germany where they met a young man called Hell who was ostracized by his peers. Yumiko and Juzo however befriended him. Yumiko would often study with Hell in private sessions with her apparently not noticing his growing feelings. However when Yumiko and Juzo were kissing in her room, Hell barged in for another session and was alarmed by this. Yumiko explained that the two were engaged. Hell was silent and left until the following morning where he tried to shoot Juzo. Yumiko knocked the gun away and Hell left never to be seen again. At some point she and Juzo graduated with doctorates, got married, and had a son named Kenzo Kabuto. It is implied that Yumiko died at some point before the start of the series as she is never mentioned again.
