Sanzenin, Azumamiya, Ookouchi, and the Hakuou Three Amiga attend beach class at Hakuou Academy on a remote island, leaving Hinagiku behind. During the flight, Hayate experiences airsickness for the first time in a private jet until Nagi holds his hand. Upon arrival, Schmidt hen Bach, the resort butler, attempts to create enjoyable memories for the group. However, the students are unhappy and wish to return home. Yukiji supports their desire to leave, but Schmidt refuses to let them go. He summons an army of cartoon characters to prevent their departure. Hayate, Himuro, and Taiga defeat the enemies, while Kaede forces Koutarou to fight instead. After the battle, the group escapes the island on a plane, or so it seems.
