Yukinari Arima is a member of Shishitoren.
A tall teenager with messy brown hair styled asymmetrically—shaved on the left, longer and lopsided on the right—Arima has a naturally rough look that matches his personality. He's almost always seen wearing the Shishitoren jacket over a white shirt.
Arima embodies the worst of Shishitoren's reputation. He's arrogant, smug, and violent, with a mean streak that extends to picking on middle schoolers on their own turf just for kicks. He'll openly mock teammates who lose fights and has no problem fighting dirty if it means winning. What's interesting about him is that he's actually observant—he quickly figured out how devoted Sugishita is to Umemiya and used that knowledge to mess with his head during a confrontation.
That said, he's not completely heartless. Despite his cruelty, Arima genuinely cares about Kanuma, and the two are genuinely close friends. It's one of the few cracks in his otherwise brutal exterior.
