鈴見 洋祐

One of Fuminori's neighbours, a kindly yet somewhat judgemental man who likes to paint. He lives with his wife and daughter in a blissful lifestyle free of want. 

However, Yousuke's life is turned upside down when Saya changes his brain to the same as Fuminori's in an experiment. Yousuke then turns insane, kills his wife and daughter, who he now perceives as hideous monsters, before raping Saya. He is killed by Fuminori in revenge./
