Tetsuke

Tetsuke works as a translator for poker dad.

Given that poker dad is a D1 football man, it is unlikely he knows Japanese. Thus Tetsuke serves as a mediator between poker dad and the 12 Japanese hitmen he is playing poker against.

Poker dad routinely asks Tetsuke to raise the stakes, but it is unknown what exactly Tetsuke is relaying to the Yakuza.
