The elderly man introduces himself as Kenzo and he points the group to his fighting dojo where he is the current Shihan. As they approach the dojo, the gang hears voices from the inside. They ask what is going on, and Kenzo replies that it’s his granddaughter’s stupid idea of training through dancing. After the door opens, Ash sees a Hitmontop dancing and checks him on his Pokédex. After the training is over, Kenzo’s granddaughter Chigusa presents herself, and Kenzo informs her that Ash will be the new Shihan. Ash reacts surprised while Chigusa is angered and she retorts that she must be the new Shihan. Kenzo refuses to pass the title on to Chigusa because he considers her training strategy to not be due to serious, and he claims that she is teaching ballet than fighting. Ash then tries to settle the argument, while Chigusa challenges Ash to a battle which will the decide the future Shihan. Ash replies he doesn’t want to be a Shihan and he even doesn’t have a Fighting-type Pokémon to battle, but Kenzo intervenes saying he should use Bulbasaur.
