Graduation looms for the founding members of the Light Music Club. With only a few precious weeks of school left, the girls decide to make the most of it and plan a trip abroad. Hawaii, New York, Dubai—many destinations are suggested, but after a little help from the club's precious pet turtle, Ton-chan, London is chosen as the host of their next misadventure! Yui Hirasawa, Mio Akiyama, Tsumugi Kotobuki, Ritsu Tainaka, and Azusa Nakano will visit famous landmarks, perform live music for Londoners, and eat all sorts of delicious food, all while stumbling clumsily from place to place. But the fun won't last forever, as heartfelt songs and goodbyes will be made as their high school days together come to a close. One thing is for certain though: the undeniable friendships these girls have formed is something that will carry on long after the final scene rolls.

On their way back from the 18th floor, Hestia, Bell, and the others accidentally uncover a hidden, mystical hot spring, and they decide to stop by to refresh themselves until creatures lurking in the dark appear to attack them.

For centuries, the magic and human worlds have been at peace with each other, though physically seperated by a magical gate. But when the powerful magic spheres are stolen and fall to the Earth below, the king of magic sends Boss, a fighter; Lime, a master transformer; and Poogie, a master morpher to retrieve them. With not much time, the trio must retrieve the spheres which, when in contact with the human world, suck up the negative emotions of household objects and become BEMs, Bug Eyed Monsters!

Due to his mother and sister, who both love professional wrestling, Kinjirou Sakamachi developed a resilient body that could take hard punches, aggressive kicks, and even deadly vehicle bumps, in order to survive their various grappling positions and locks. However, he also developed gynophobia, an abnormal fear of women. With just one touch from a girl, his nose bleeds uncontrollably, he sweats excessively, and in rare cases, faints abruptly. His life changes for the worse because of a fated meeting in the restroom. While trying to escape from a girl, he discovers that the most popular student in their school, Subaru Konoe—the butler of the headmaster’s daughter, Kanade Suzutsuki—is actually female! Surprised, Subaru violently assaults Kinjirou, dealing significant damage and knocking him unconscious. When he comes to, he meets Kanade. In exchange for his silence, she promises to help cure his phobia.
