The student council president. Her grandfather is the head of the Kuhouin Group which is at odds with the GHQ, and Arisa is his heir. She however does want that, but is unable to face it, resulting in her Void "The Coward's Shield", which is a disk-shaped shield controlled by a ball-shaped device. The shield can divide itself in 6 parts, and even grow in size.
