The Pure Yet Impure Grappler / Trespassing on Good Faith (2x5)

:

The Pure Yet Impure Grappler: Sousuke and Kaname ask the school's karate club to vacate their dojo, which is slated for demolition. However, the club refuses to leave, challenging Sousuke to a duel where they'll leave if they lose. Sousuke defeats the club's members with relative ease until he faces the club president, Issei Tsubaki. Trespassing on Good Faith: As a test of superiority, Sousuke and Issei compete to care for the injured school janitor; however, their overzealous efforts do more harm than good. The janitor tries to be patient, but finally goes berserk when they accidentally serve his prized koi pet to him for dinner.
