Height: 170 cm

Nanao Kisaragi is Kaito's cousin. His hair is a bit curly and bright. He has a natural prince temperament with super positive thinking and has his own fan club. He gets along well with Ryouhei, and the two have a lot of fun together. When Kaito gets upset with Nanao, he calls him "Kaa-chan." He secretly worries over his height. For some reason, animals don't like him.
