The Second Young Lady of the Yukinoshita Family

As the adopted second young lady, Yukinoshita Tsukino is different from Harano Yukino. She is not bound by family rules, but she is extremely smart. To Harano, she is a naughty sister who always likes to tease her. To Yukino, she is a good sister who cares about her. She is their only comfort in this family. However, she is extremely slow about feelings. Her abnormal love and concern for Harano and Yukino are just normal interactions between sisters.
