Shun Midorikawa  

, 緑川 駿

Kusakabe Unit member Shun Midorikawa has a personality similar to that of a "puppy eager to show off its abilities," as described by Yoneya. This was demonstrated when he easily defeated Osamu ten times in front of a large audience. However, when Jin, who had previously saved him, was present, Midorikawa acted foolishly and energetically, likely due to gratitude.
