A soft, almost cheerful humming sound echoed in the deserted corridor.
Retsu, the 'school nurse', was meticulously cleaning the tiled floor.
She wasn't using a simple mop; she was utilizing a small, specialized, portable cleaning device with concentrated disinfectant, eliminating every last smear of blood and organic residue scattered across the immaculate white surface.
And despite all the blood scattered all across the hallway, her white coat, surprisingly, remained pristine.
A few feet away, lying grotesquely against the wall, was Hipuno Shisou. His body was bent at several inhuman angles, twitching sporadically, a silent, pathetic effigy of pain.
Countless thin, silver acupuncture needles were pierced precisely all over his body—in joints, pressure points, and along his spine—immobilizing him while keeping his nerves violently alive.
After she finished the detailed cleanup, Retsu breathed a slow, satisfied sigh of relief.
