Muto Yuzuki was ready for a whole new life and a different self when she
got to middle school but she didn't expect it to be literally
torturous. Yuzuki is “persuaded” by an upper classman named Funaki Aoi
to join the Torture Club on campus which has been secretly training
students to enter the field of military and police organizations as
interrogation experts. Aoi sees something inside Yuzuki and thinks she
might be a prodigy in torture methods. Naturally, Yuzuki wants nothing
to do with such vulgar conduct but the more she spends time with the
club, the more she starts to realize her own dark potential.
