The Hard Sell Fetish / The Patient of Darkness (S02E04)

Sousuke and Kaname approach the karate club to ask them to vacate their dojo, which is set to be demolished. The club refuses and challenges Sousuke to a fight, promising to leave if they lose. Sousuke quickly defeats the other members, but his toughest challenge awaits with the club's captain. To prove who’s superior, they decide to compete in taking care of the injured janitor. However, their over-the-top attempts backfire, and the janitor, initially patient, loses his temper when they mistakenly serve him his beloved koi for dinner.
