Kyoya's big sister, the only hostress

Uta, Kyoya's older sister, twin sister. She was quiet but when she was dared to flirt nobody could resist her. She had the perfect figure, feminine face, motherly personality and all the things that was seen as beautiful. She rarely speaks above a whisper, which surprises people when they see her outstanding height. At 6'2 she is 2 inches smaller than Takashi, and she loves her bunny Pika, and Mitskuni is always cuddling the little thing. She is cold toward the energetic trio, though she speaks with Mitskuni and Takashi, her brother is her everything. She would do anything for Kyoya, she has went far enough to pummel the three idiots. She is the strongest in Japan, just barely able to beat Mitskuni in a fight. She is an experiment of the government, many tests were run on her which changed her physical abilities slightly.
