Yuuichi Tsurugi  

Vladimir Blade, 剣城 優一

Kyousuke's brother is a kind and caring individual who saved him from falling down while retrieving their soccer ball. Although he enjoys playing soccer, he understands that his condition prevents him from participating in games. When he learned that Kyousuke had discussed surgery with Kuroki Zenzou, he became angry at Kyousuke for seemingly abandoning their shared love of soccer.
