He is a mirror image of the blonde, opposite-parted Atsumu. He has slightly droopy eyes and a cool facial expression. • Personality: The stopper for the often-reckless Atsumu, remaining calm and clever during matches. However, at his core, he is just as competitive as Atsumu and incredibly stubborn regarding volleyball and food. Twin fights are a daily occurrence.
