This time they fight until both are exhausted. Kitazaki tries to join in the fight as Delta but both Yuji and Takumi make it clear that this is a fight between the two of them. Kitazaki decides to fight the winner. Kitazaki is losing interest in the Delta gear. After telling Itsuro that he threw the belt away, he gives it to Aki.
