Suoh's twin sister.

Sara is a high school student who harbors complex feelings towards her brother.

To Suoh, Sara is an angelic sister with a loving nature and endless affection; an image she cultivates and builds on daily. To everyone else, however, Sara is narcissistic and thoroughly two-faced. Family aside, Sara doesn't care for other people in the slightest, and as a result of her desperately trying to hide this fact, her family mistakenly believe Sara to be bipolar.
