Ouka Hayasaka

Ouka Hayasaka is a student president of Ginsei Private Academy and the older twin sister of Shusui Hayasaka. Along with her brother, she was a Familiar of the L.X.E. but eventually left and began to work for Papillon, to save Kazuki Muto. Ouka is a polite, soft spoken and well mannered girl who is almost always calm and collected even in confrontations which she often prefers to avoid. She is very caring as shown when she shows her concern for Kazuki Muto when he was overworking himself and Shusui Hayasaka whom she cares deeply for. Underneath her innocent exterior she is extremely intelligent and calculating, often using her status and innocent looks to her advantage. Shusui noted at the end of the series that she has an evil streak. Like her brother she becomes obsessed with their dream, to become homunculi so that they can live together forever, she even joins the L.X.E. alongside her brother for this cause. Eventually however she realizes what they are doing was wrong and learns to have faith in other people. At this point she even cries in happiness over the fact she can trust other people. Ouka is not unflappable however, as she has been rather heavily (but understandably) shocked by many of Papillons truly outrageous antics (namely the time he went to the beach in his underwear). According to Nobuhiro Watsuki, she likes Shusui, espresso and pearl pink colors, and she dislikes "The world that entraps us", society and happy people. Her hobby is having pretend wedding ceremonies and her special ability is her appearance of harmlessness.
