Kinue Kinagase

Kinue is possibly Senketsu's first user.

Background
Presumably related to Tsumugu Kinagase, she was also a fellow researcher of Isshin Matoi. She believed there existed a strong bond between people and clothing. As such, she volunteered to be the test subject to equip a Kamui (which may or may not have been Senketsu while he was still a prototype). Unfortunately, she was overwhelmed and killed. While her body was being ripped apart during the experiment, Isshin, Aikurō and Kinagase could only watch in horror.
