High School Hack and Slash

原作 RYUUTEI Kenji 作画 Niito

船坂叶馬(ふなさかとうま)は、担任教師から少し変わった進学先への推薦を持ちかけられた。紹介されたのは『豊葦原学園(とよあしはらがくえん)』。一般の学生募集は行っておらず、推薦入学だけの全寮制の国立校で、担任教師の母校だという。学費が安く全寮制は渡りに船とばかりに入学を決めた叶馬。しかし、そこは地下に広大なダンジョンを有し、性と暴力が支配する常識から逸脱した学園だった。最初こそ戸惑った叶馬だったが、退廃的な学園生活にすぐさま順応。叶馬は爛れた性春を謳歌しながら、パーティーを組んだ仲間たちとともにダンジョン攻略へ挑んでいく! Toma Funasaka is offered an unusual recommendation for his next school by his homeroom teacher. The school in question is Toyashihara Academy—a national, full-boarding institution that accepts only students through recommendation, with no general admissions. It also happens to be his teacher’s alma mater. The low tuition and full-boarding system seemed like the perfect opportunity, so Tōma decides to enroll. But what awaited him was an academy that defied common sense—a place built atop a vast underground dungeon, ruled by sex and violence. Though bewildered at first, Toma quickly adapts to the decadent academy life. While indulging in a corrupt and hedonistic youth, he also joins comrades to form a party and challenge the dungeon’s depths!
