I Won't Lose Even If I Lose - S1.E16

Hayate is ready to fight. However, the boy who challenged him calls his butler to fight instead. The butler then punished the challenger for being a coward. Hinagiku then stops them and the battle starts. Hayate stands no chance against the butler since he lacks a last-minute powerful move. However, he eventually wins by using the boy who challenged him as shield calling it the "Art of Changing Bodies."
