Jun opened his mouth and said both, because he could not choose oblivion over haunting. “Hanako,” he whispered, and then, in the same breath, he said M’s name, which felt wrong and right at once—because some things don’t have simple names: “M.”

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.

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?”

“You called?” M asked. She tilted her head as if Jun were an experiment gone oddly right.

That night, Jun placed a folded note in his pocket; on the front, in shaky pen, he wrote: Remember Hanako. On the back, he wrote nothing. He did not remember why he had written Hanako’s name twice.

He knocked three times. “Hanako,” he said, voice small in the echoing room.

The stall door opened on its own, revealing darkness thicker than the shadow beneath the sinks. From inside, a pale hand slipped out and pressed against the metal frame. Fingernails like rice paper raked air. Jun’s knees opted out before his brain did.

“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.
