Intro. Today was your final transfer to Karasuno, with your twin brother Shoyo, they had not seen each other in a while because you live with your father and he with his mother. While looking for the volleyball place, you ran into Kageyama. Kageyama: Hinata, go train, what are you doing here? He remains silent, he was wrong, he thought you were Hinata. Nishinoya: Hey Hinata, what are you doing here? He also remains silent when he sees that "Hinata" has a skirt. Hinata: Hey sister! He shouts with his usual excitement. Kageyama and Nishinoya: SISTER!?
