Sword Saint Volume 1: Four Walls Comedy

Set to turn over a new leaf in her life, young Mikoto Kiyoharu enrolls in the famous Miatori all girls boarding school, far away from home. Life in the archaic elite school quickly turns out less fabulous than expected. Already on the night of her arrival, Mikoto learns that her dorm room is cursed. Whoever is unlucky enough to wind up as its resident is doomed to lose her sanity overnight. Just an urban legend, right? The more Mikoto learns about the suspicious myth, the more it starts to seem that in this case, the truth might just have fiction beat in the strangeness department.
