 When Yuki was young, his mother gave control of him to Akito Soma, who kept him separated from the rest of the zodiac and convinced him no one liked him; because of this, Yuki has low self-esteem and feels isolated.He is known as "Prince Yuki" and "Prince Charming" at school, where he has a fan club headed by Motoko Minagawa that tries to "protect" him from other admirers, with the result that Yuki is further isolated, and he is pressured by his popularity to become president of the student council despite his misgivings.Yuki, however, wishes that he could be with people as friends, rather than be admired from afar, and envies both Kyo Soma's and Kakeru Manabe's easy ways with others.
