She didn’t even nod, just stood in the arena, waiting for more opponents to come before her, blood dripping from her Quinque.
When the rest of the Doves filed in, they noticed the two slain investigators, and Jin, whom held the Quinque that dropped with their blood. They were far more cautious about approaching her, and after an intense battle, had subdued Jin. After Jin was subdued, the rest of the cult remaining within the building was hunted down and killed, and Jin was taken to hospital under close supervision. When she was brought into hospital, the first thing they did was set about cutting the lock off of Jin, which was heavily rusted shut from blood and water, and when the helmet was removed, the girl was confirmed to be the heiress to the Kawabe estate. She was severely malnourished, underweight, and had many old injuries to her body. One of her arms had been broken and never set properly, which lead to her needing corrective surgery, and her eyesight was rather poor from the helmet being constantly locked into her head. The doctors believed that her physical condition would improve overtime with proper care, but were uncertain about her mental state. She didn’t speak, even when spoken to, only giving an occasional glance with dead looking eyes. She seemed to have lost some mental functions such as the ability to preform basic hygiene, and her hair had for the most part amassed into a single large mat which required most of her hair to be cut off, but nothing quite seemed to scare her. They drew blood without issue, even preformed various different physical exams, and all without any form of traumatic breakdowns, she only ever stood or sat in wait.
It would take nearly an entire year of rehabilitation, medications, and therapy for her to somewhat resemble a normal high school aged girl, but she was still incredibly withdrawn. With no more living relatives left, she became a ward of the state, and was quickly taken into the custody of the CCG, who moved her to one of their academy programs. They housed, clothed, and fed her, even put her into their very own school so she could start her education where she had left off, but her eyes never changed. She looked more like a doll, lifeless eyes always staring right through people, and quickly, she was ostracized.
