Yui's older brother and a member of the idol unit WITH. Outwardly Shogo is charming and kind. He loves to excite his fans and relishes being chased after by them. He is a quick thinker and manages to turn poor situations into good publicity for himself, but he has a short temper when it comes to someone making him look bad or getting in his way. Towards Yui he is an emotional bully. He often claims to be embarrassed because of her and only shows his "true" personality around her.
