剣城優一

説明

A very nice, kind, and caring brother of Kyousuke. In the past he saved Kyousuke from crashing after falling down from a tree to get their soccer ball. Even though he loves soccer, he still accepts the fact that his condition won't enable him to play. When he heard Kyousuke talked to Kuroki Zenzou about his surgery, he got mad at Kyousuke for "abandoning" the soccer that they both love.
