Manami Kinjou
About
After moving into Kio's house, her dormant feelings for him begin to resurface, especially after realizing that the only reason Kio treated her like one of the guys was because he was under the mistaken impression that Manami had a boyfriend named "JACK" that he would overhear her talking on the phone to sometimes.
Manami has a personal asisstroid named Yun Fat (most likely named after Cho Yun Fat). He has black hair, as opposed to the usual reddish-orange, wears a black suit and a pair of sunglasses with a cigarette, and attacks with a pair of energy pistols.
She later admits to Aoi that the reason she pushed her so hard to pursue Kio was so that she would be able to give up on him. She believed that she waited too long to confess her feelings to Kio, and so wanted Aoi to have her shot first.
