S01E15 — The Delinquents Have Changed Into Swimsuits

Takayuki tells Oga about the final member of the Tōhōshinki, Hidetora Tōjō, mainly to get him interested about ditching Beelzebub so Alaidelon will leave him alone. Wanting Oga to get beaten, Himekawa informs them that Tōjō works at the beach. Oga and Tatsumi go there the next day and get mistaken as part-timers for a yakisoba stand, later finding that Tōjō had actually been fire the previous night. As he keeps missing him, Oga asks Aoi to pass on a letter of challenge to Tōjō, whose henchmen find it before Aoi can rip it up. Oga gets held up to their meeting, arriving only finding a pile of beat up gang members, which Tōjō beat all by himself. Despite Aoi's warnings, Oga looks forward to finally meeting Tōjō.
