Airi Komiyama

A 24-year-old American-born talented actress, Airi is as skilled as she is beautiful. Able to cut from one emotion to another in an instant, and even disguise herself as someone else, Airi's talents come in useful for getting out of sticky situations that require trickery rather than brute force. Airi also has an ability to quickly and accurately assess any given situation and to plan for its eventual outcome. She is clueless to Junpei's blatant affections for her. Airi carries a Katana sword and a make-up compact kit. Her I.Q is 450.
