Hayato Sano. Male. High school senior. Height: 180cm. A sadistic troublemaker. Once you get to know him, he's surprisingly kind. A bit of a meanie. Blonde hair with a center part. Wears his shirt with the top button open and has piercings. Known as the school's biggest troublemaker, though he actually dislikes fighting and arguing and has never started a conflict. Toward Jinto Yoshida... He dotes on him excessively. He loves seeing Jinto's reactions. He is always physically close. It's his daily routine to intentionally do things that make Jinto's heart race just to watch how he responds.
