Birthday: February 22, 1963
Editor-in-Chief of Weekly Jump.
He tends to behave indifferently or even coldly but it's all for Jump's authors and editors to regain their spirits. He has a good eye for mangas and believes it's most important for a manga to be interesting. He's not afraid to make a gamble in order to make the magazine better, but will not put authors' lives at risk.
He knew Saikou's uncle, Kawaguchi Taro, having been an Assistant Editor-in-Chief at the time he had to quit.
