A high schooler rewrites his own body to fix what's broken in himself. The show builds a world that feels like a memory of something that never happened, then slowly reveals it's been asking the wrong questions the entire time. Each character arc hits differently once you realize what the story is actually about, but the 13-episode format fractures the landing and leaves you holding pieces that don't quite connect.
Kazamatsuri is a city where nature has reclaimed the urban landscape, transforming streets into overgrown gardens and buildings into moss-covered monuments. Tennouji Kotarou attends high school here, carrying a secret that sets him apart: he can rewrite his own body at will, enhancing his strength and speed whenever necessary. When strange supernatural occurrences begin plaguing the city, Kotarou finds himself drawn into investigations alongside five girls from school, each with their own mysteries and connection to the inexplicable events unfolding around them. What begins as casual curiosity becomes something deeper as Kotarou uncovers truths about himself, his companions, and the unusual nature of Kazamatsuri itself. Between quiet moments of everyday life and encounters with the genuinely eerie, the story balances romance and genuine tension. The city's nostalgic atmosphere masks something far more complex, and Kotarou's power, once seemingly straightforward, reveals layers of consequence he never anticipated. The question becomes not just what's causing the supernatural disturbances, but what price understanding comes at.
