Keisuke Hirose

Ishida's other best friend in elementary school. He is a fat boy who often went alongside Ishida in his "life-challenging activities." Like Shimada, Hirose shunned his friendship with Ishida and bullied him for having bullied Nishimiya. Hirose stays close with Shimada (and possibly Ueno as well) after graduation and along with him brings Ishida from a river after he falls down from saving Nishimiya. (Source: Wikipedia)
