Episode 1: Ultimate Fight: Dragon's Fist

Souichiro Nagi is sent off with Aya Natsume for special training for the tournament. He is surprised to see his mother Makiko Nagi as well as Dōgen Takayanagi there. Annoyed, Souichiro decides to leave, taking Aya with him. On his way home, Souichiro thinks he could take on Aya any day, but Aya wields her sword right in front of him to prove otherwise, having him realize how weak he really is. Suddenly, they are attacked by several men wearing masks. Meanwhile, Bob Makihara is training with Maya Natsume, dragging her while sprinting with a tire attached to a rope. Souichiro channels his energy and transforms into a stronger self, changing his hair from blonde to black only for a moment. The men are actually under Dōgen, who have ties with his family. Makiko tells Souichiro that he is just a fragment of the universe and vice versa. Elsewhere, Bunshichi Tawara tells Mitsuomi Takayanagi to stop holding on to all what happened two years ago. While riding his motorcycle, Mitsuomi later gets into an accident due to a stray cat. Aya scolds Maya for using Souichiro only to fight Mitsuomi for her own benefits, running away in tears.
