Ichihime Yukariki

When she was twelve years old, she led an attack on the Zerozaki Clan, along with Tamamo Saijou and Shiogi Hagihara. She was saved by Jun Aikawa and Yuma Shisei. She suffered damage to her frontal lobe, which caused her broken speech and problems with socializing. She was taught to use string as a weapon by Shisei, who was a teacher at Sumiyuri Academy, and then went on to become a student there.
