Fue Yobuko

Like all members of the Public Morals Committee, Yobuko is dedicated to upholding school rules, and will not hesitate to use violence if she deems it necessary. Though she usually appears quite cordial, Yobuko reveals a rather psychotic side when dealing with troublemakers on Unzen’s orders. As Unzen's partner and second-in-command, she appears to be in a much more intimate relationship with him than mere fellow workers. Yobuko lets him sit in her lap, feeds him, and even lets him nestle his head in her breasts for comfort.
