Ushiro Yuuga is one of the five main antagonists who bullied Shun Uruma in their middle school years.
SpoilerUshiro Yuuga is a juvenile and sex-driven delinquent. He appears to be well versed in emotional manipulation, threatening one of his female employees with a lighter under her tongue and proceeded to tell her that she is absolutely necessary. He is also notably misogynistic, seeing women as nothing but tools for pleasure and nothing more. This even extended to his girlfriend, who he kept chained naked and repeatedly raped.
