Kirie Bonin is a human being who got infected by a matter assimilating cube during an incident at Refinoc, now having the abilities of said cube (matter assimilation and 12 floating red transparent blades that appear behind her back). She shows no sort of emotion towards anything and keeps the same deadpan expression on her face, as if it's her main emotion. Although she may look miserable, she does have a rebellious side, however. She suffers from psychotic depression.
