[Tearontaron] Oumagatoki no Kagami | The Twilight Mirror

A quiet school after hours becomes a claustrophobic trap when a uniformed girl encounters the elderly teacher Mr. Kadoyama and follows him through deserted rooms and shadowed stairwells. Their unsettling exchange turns coercive, while fractured mirror imagery and a stark final encounter leave her standing alone beside the stairs, questioning what was real and what the school has awakened.
