Tsuyoshi Isobe

Kyasharin has hair dyed brown and is a completely emaciated bag of bones, in part due to his addiction to vitamin supplements. He joins the club in order to become stronger, and for a brief period does become stronger, giving up the vitamins for food and exercise. Unfortunately, his reliance on vitamin supplements continues, and every time he takes them, so does his spasmatic cry “Okure-nisan” (a reference to a Japanese comedian Mr. Okure, who is also extremely thin). He was also the ace of his baseball team in middle school.
