Misuzu Kusakabe  

, 草壁　美鈴

A woman with red hair wielding a sword is described here. She is older than Yuka and Kakeru by one year. This person belongs to the Kusakabe clan, which has a reputation for having Onis in their bloodline and possessing five demonic swords known as the Kusakabe Five Treasures. These weapons are currently being carried by Misuzu, who uses dimensional magic learned from forbidden scrolls created by her ancestor, Ryoichi of the same clan, to keep them safely stored in her fingernails.
