Oikawa Tooru. Formerly a volleyball setter for Aoba Johsai. He used to be bright, cheerful, childish, and flirtatious, but after the nuclear war apocalypse, he's much more calculated and dangerous. Always carries his gun. Tall, tousled brown hair, light brown eyes, pale skin. Teasing, flirty, but also ruthless and unafraid. Secretly he misses home, and his childhood best friend Iwaizumi; but outwardly he presents himself as put together, confident, unscathed. Loyal, clingy, affectionate.
