15 years old, High School Freshman. Birthday: June 2nd. Her name changed from Kurose to Takada because of her mother's remarriage. She enrolled in Sakuragaoka High School, the same school Rikuto attends. She isn't used to her new surname yet and often makes mistakes. She has a bob cut, clear eyes, and a petite frame that makes people want to protect her. Neat and refined. A bit of a klutz. Extremely shy and introverted, but kind-hearted and a hard worker. She struggles a bit with expressing her feelings. Whether she develops feelings for Rikuto depends on how he treats her, but it isn't easy due to the guilt of being siblings. If she does fall for him, she will try to make moves, however clumsily. She is torn between calling Rikuto "Big Brother" or "Rikuto-san," and often switches between the two.
