Tsubasa Shibahime is has been in love with Arima for a long time, however he sees her as the little sister he never had. She is very cute and *extremely* short tempered. In fact, she can be quite viscious when offended. Although Tsubasa tried many times to tell Arima that she loved him she was thwarted at every turn. When she discovered that Yukino had become Arima's girlfriend in her absence she went ballistic, to say the least. When Yukino finally cornered her, Tsubasa poured out her story. Arima was quite surprised to hear of her feelings toward him, however when all was said and done she finally gave in.
