草壁 美鈴

A red-haired swordwoman. She is one year older than Yuka and Kakeru. She is an Onmyoji from the Kusakabe clan, a clan of Onmyoji that is famous for having Oni's blood in the bloodline and the five demonic swords known as Kusakabe's Five Treasures. Misuzu possesses all five swords, keeping them in her fingernails by using dimensional magic that she learned from forbidden scrolls that were created by one of her ancestors who learned and incorporated Western magic, Kusakabe Ryoichi./
