Hundred

Humanity faces an existential threat from the Savages, mysterious extraterrestrial life forms that have descended upon Earth. The only means of combating these invaders is a specialized weapon known as a Hundred. Driven by the ambition to master this technology and become an elite Martial Arts Master, Hayato Kirasagi successfully earns admission to Little Garden, a prestigious university built aboard a massive battleship. However, his new academic life quickly takes an unexpected turn when his roommate, Emil Crossford, greets him with unsettling familiarity, passionately declaring how much he has wanted to see him. Despite Hayato having no memory of their prior acquaintance, Emil seems to know him intimately, leaving the young recruit deeply uneasy. Hayato's troubles multiply almost immediately after the entrance ceremony concludes. He finds himself challenged to a formal duel by Claire Harvey, the undisputed strongest fighter on campus, who commands respect under her imposing title of "Queen." Thrust into a high-stakes confrontation far earlier than anticipated, Hayato must navigate strange personal mysteries and overwhelming combat trials. Surrounded by enigmatic allies and formidable rivals, his journey at the ultimate academy for warriors begins here.
