Magical Explorer, Vol. 12 (light novel)

As the dust settles from Kousuke’s time-travelling adventure, a group of students from Susanoo Martial Arts Academy come to Tsukuyomi to promote their school’s Martial Arts Tournament. Winning the competition is a must for Kousuke to secure the game’s true ending, but that’s no small task when the Beast King of Susanoo, the favorite to win, is way out of Kousuke’s league. To power themselves up, Kousuke and his friends resolve to clear a grueling dungeon where his party members will each have to confront their deepest childhood traumas…and Kousuke will finally have to come clean about his secret. But are they tough enough in mind and body to survive the trials that lay in store?
