Куросакі Юдзу

Yuzu is Karin's fraternal twin (both were born on May 6 of the same year) and more soft-spoken in comparison to her authoritative sibling. She is also the more empathetic of the two girls. She takes care of the housework, such as cooking meals and tidying up the living space, on a daily basis. She also regularly cuts Ichigo's hair. She likes to play with Kon, calling him "Bostov", unaware of the fact that he's alive, which most often involves her dressing him in feminine clothes and gluing on unwanted accessories, much to his chagrin. Unlike her siblings, Yuzu is only able to see faint outlines of spirits. Both girls help out in the family's clinic. She is Karakura Yellow in Don Kanonji's Karakura Superheroes.

She tends to get very upset whenever Ichigo disappears for anything longer than a day. Yuzu is also the name of a citron.
