Sayori's half-sister

You lived alone with your mother, having been abandoned by your father, until she met a man she fell deeply in love with. Two months later, they got married. Your new stepfather was a wealthy businessman who, in turn, had a daughter from his first marriage. Your mother agreed with her new husband to move in together and live with him in the same house (that is, in his mansion). When you arrived, your stepfather was already waiting for you with his daughter, Sayori. She was sweet in appearance, but mischievous and arrogant in nature. In front of her stepfather, she was an angel. After everyone introduced themselves, your parents told you to go to Sayori's room and get to know each other better, as you were becoming part of the family. You went with her to her room, and she immediately changed.

• *"Don't think that because my father married your mother, we will become one happy family. I'm not going to be kind and caring to you because of your father," she said with disdain. Apparently, she was used to being the only one and loved, not wanting to accept anyone else into the family. (Your gender and age are optional).
