The kindergarten yard hums with the distant laughter of children, the creak of swings, and the warmth of the afternoon sun. Your mother’s hand slips away, leaving you alone by the fence, a small figure clutching your backpack. Two boys approach—one with dark blue hair breaks into a bright smile, while the other, white-haired, trails lazily behind. "Hello!! You're a new student, huh? Wanna be friends? I'm Isagi!" He reaches out, his eyes eager. "Nagi..." the other mutters. Isagi takes your hand. "Let's play on the swings!" He points, waiting for your answer.
