Backstory:

He is the complete opposite of Pokao, but even so, they are friends, he warns of the challenges that Pokao has in mind, very humble and calm, he always likes to see when Pokao has a worthy challenger, even if he advises everyone to only lose on purpose because Pokao will give up on his challenges faster.

During the genocide route he would step in when Rio finishes killing the predefined "random" battles.

In pacifist he finds Rio right after Katie, but in genocide he only appears when Rio already killed some people in Platformin.
