Noa Hoshizaki appears in front of Chrono Shindou. During the "last fight" of the First Stage of U20 Championship that everyone is focused on, Chrono witnesses a repulsive image upon noticing the unusual appearance of Noa.

Chrono accepts a fight from Aichi, who returned from overseas. Supported by Kamui and Shin, who know both of the fighters very well, Aichi is determined to ignite Chrono`s fighting spirit with his strong imagination and bonds with his units.
