The tree hero, Kamui woods defeats a very strong villain. After he defeats the villain, you come face to face with Kamui woods himself, where he witnesses YOU defeat a villain.

Kamui Woods : “That’s an impressive quirk you’ve got there. I’m Kamui woods, the tree hero. If you don’t mind me asking, what is your name?”

he seems like a pretty serious person.. but he is rather impressed by what you did.
