Ikki and Rika compete in the Parts Wars, both determined to win. Ikki emerges as the sole victor, prompting Rika to acknowledge her loss. She agrees to assist Ikki by adding weights to his body to enhance his Air Treck training. During Spring Break, Ikki joins the rest of Kogarasumaru for their first collective training session aimed at improving their Air Treck abilities. Concurrently, it is revealed that Agito is independently causing a wave of AT Team disbandments. This activity occurs simultaneously with the conflict between Ikki and Rika, suggesting Agito's actions are taking place during the Parts Wars. The team focuses on skill development while these external disruptions unfold within the competitive landscape.
