Welcome to the Maken-ki
This time Takeru walks in on Haruko. In order to mollify her, he asks for an explanation of the kenkeibu. After learning that its mission is to ensure the fairness of duels and to protect the duelers, Takeru commits to joining it, as do Kogen and Inaho, each for reasons of their own. The new-member welcoming party is held at an onsen, but since it is co-ed everyone wears a swimsuit (this does not stop Takeru and Kogen from ogling their cohorts). The intrusion of a bear provides the chance for everyone to show off their abilities and demonstrate the spirit of maken-ki.
