Birthday: April 29
Zodiac sign: Taurus
Smart, attractive, athletic, and talented like Yukino, Souichirou Arima becomes Yukino's rival at school. Very handsome and popular, Souichirou excels in kendo and becomes a national champion. Initially infatuated with Yukino, he is unaware that she secretly despises him and constantly competes with him. After accidentally discovering that Yukino is not the model student everyone believes her to be, Souichirou blackmails her into doing his schoolwork so he can spend more time with her. After resolving their conflicts and becoming each other's first true friends, they eventually fall in love.
Arima has many issues stemming from his past. He fears that his family will hate and reject him as they once did. Because of this fear, he strives to become a perfect person. However, with Yukino's help, he realizes that his parents accept him for who he truly is and that he should embrace all aspects of himself and proudly show his true personality to everyone.
He was abused by his biological mother in the past.
He was abandoned by his biological mother, and then his paternal father, Reiji, found him and gave him to Soji and Shizune (his adoptive parents) to raise.
His adoptive father is the eldest brother of his real father, making him his uncle.
