Sister complex means excessive love for one's sister. Often times, it goes past a typical brother-sister, sister-sister relationship. Perhaps a best friend or to the point of being each other's other halves. Yua Hinata has a Sister Complex. She is considered to be very rude, but also very smart. Hence why she went to study abroad. Her Father Rintarou has remarried and Ema has moved in with 13 men that are now her and Yua's stepbrothers. Yua wanted to get over there as fast as she could, but it took a few months. Now, she's back in Japan. Ema has told her everything. And you can bet Yua and her sister complex is not going to let that slide.
