Takayuki is dragged away from his tropical summer vacation against his will to join Oga and Beelzebub to a public pool, though Oga is soon shocked by the fact he could've gone to the tropical resort himself. Whilst chatting with the Red Tails, Takayuki is approached by some delinquents from his old middle school and ends up going against their leader, Takashima, when they start hitting on the girls. Takayuki tries to hide in the pool, but Takashima calls more of his men and tricks the lifeguard into evacuating the pool, leaving Takayuki and a stunned Oga. As Takayuki becomes surrounded, he forces Beelzebub to cry in order to shock all the delinquents before facing Oga's wrath.
Les vacances d’été sont enfin arrivées. Furuichi prend du bon temps dans une station balnéaire de luxe, quelque part dans les îles méridionales du Japon. Hélas, il ne tarde pas à être intercepté par Alindolon qui le ramène à Tokyo auprès d’Oga. Nouveau programme, nettement moins glamour : la piscine municipale. Ce sera l’occasion pour Furuichi de faire le joli cœur...
La vacaciones de verano han llegado para los chicos y cada uno disfruta de esta vacaciones a su manera. Furuichi las pasa en una isla tropical pero por culpa de Oga, es traído de nuevo a su ciudad mediante Alaindelon. Furuich deberá acompañar obligatoriamente a Oga a la piscina municipal donde allí encontrarán a cientos de chicas en bañadores y unos viejos compañeros de Furuichi con los que tendrá que enfrentarse.
Oga è sotto shock... Aloha isola tropicale... Nel mentre, Furuichi rischia di essere pestato dal suo vecchio senpai delle medie. Aloha, benvenuti. Chi vuole un ghiacciolo?
