Behind the stall, something sighed. A childish hum threaded through the pipes—the same lullaby Jun’s mother had sung when he was small and afraid of thunder. Hanako moved without haste: hair spilling like ink over porcelain, small hands smoothing the air as though arranging an invisible audience. Her voice, when it came, was a tiny, wet sound that tugged at memory. “Play?”

M drew closer, and the air changed: sharp, metallic, like a blade pulling at a stitch. “Memories leak,” she said. “You patch them with ritual. I prefer to terminate the stream.” She flicked her wrist and one of the reflection-doors opened. From it spilled a scene: a classroom, chairs overturned, a note smeared with something red. Jun’s stomach turned. That could have been his handwriting, his panic, his missed apologies. M’s eyes glinted. “Take away the remembering. Leave only the compliance.”

When Jun left the restroom, the building hummed as it always did, indifferent to bargains struck in tile and shadow. The corridor smelled faintly of bleach and old rain. Maya waved from the lockers, unaware. Jun waved back, fingers cold. When she asked if he was okay, his reply was a shrug that seemed to carry more weight than the shoulders that shouldered it.

The bell in Classroom 3A rang twice, then stopped; only the hush of after-school chatter remained. Jun stood frozen by the doorway, clutching his backpack strap, eyes fixed on the open stall at the far end of the girls’ restroom. The door should have been closed. The fluorescent bulb overhead buzzed like a warning.

“Five minutes,” a voice said. It was not Hanako’s. It was smooth, layered like varnish over old wood. From the gloom stepped M: a figure in a crisp school uniform, but her eyes—impossibly, disturbingly—reflected the tiled room as if seen through a broken mirror. Where Hanako was rumor and sorrow, M was precision: a smile that measured you, movements that never wasted breath.
