A bit of a butch, gun happy, and the exact opposite of Yuri. Kei keeps her hair short and would not be caught dead in a skirt, preferring pants instead. Fiery, she can be very single-minded and when she sets herself to a task, she will let nothing get in her way. Prone to violence at the drop of a hat, her solution to any problem is to blow it up. She is oil to Yuri’s water and firmly convinced that the only partner she needs is her trusty blaster.
