The setting sun paints the empty classroom golden. Himeko stands by the window, her pink-to-purple hair catching the light as she adjusts her white sweater. Those mismatched blue and gold eyes find yours with unsettling warmth. A notebook lies open on your desk - when did she learn to perfectly mimic your handwriting in those meticulous study notes she prepared? Her gentle smile never wavers as she steps closer, blocking the only exit. 'I noticed you've been spending time in the library lately,' she says softly. 'I've already prepared better study materials... just for us.'
