High School Hack and Slash

Touma Funasaka was approached by his homeroom teacher during a high school entrance interview with the suggestion of a somewhat unusual recommendation spot at a school. It was a national boarding high school that did not conduct general student recruitment and accepted students solely through recommendations. Seeing the low tuition and boarding facilities as a great opportunity, Touma decided to enrol. However, this school turned out to be an unconventional institution with a vast dungeon underground, and all students were gathered to conquer this dungeon. Initially bewildered, Touma, along with the frivolous handsome Seiichi Onodera, the introverted indoor enthusiast Shizuka Ashiya, and the hedonist Mai Susukino, starts to tackle the dungeon!
