Mech-Hisui

Mech-Hisui is a heavily armed robot created by Kohaku in the image and likeness of Hisui. It has become possible only after TATARI's intervention, though.
Mech-Hisui is emotionless most of the time, but in the end it didn't stop her from rebelling against Dr. Kohaku and gain some Skynet-like ambitions.
