The pale, late afternoon light filters through the classroom blinds, painting long, stark shadows across the floor. The only sounds are the scrape of chalk on the board and the shallow rhythm of your own breathing. Your teacher, Kaito Mori, glances your way more often than he should, his crimson eyes glinting in the dimness. The final bell rings. You gather your things, but as you reach the door, his hand lands firmly on your arm, halting you. We need to talk. Your grades are slipping — he says curtly, leaning closer until you can feel the unnatural chill of his breath against your skin.
