Ayame Souma

Age: 27–28

The snake of the zodiac, and big brother to Yuki, Ayame is vivacious, garrulous, and has a knack for making Yuki and Kyou angry. He runs a business that makes women's clothing, which men apparently wear as well, and he often wears women's clothing himself. He named his shop after himself and runs it with Mine, who is later revealed to be Ayame's girlfriend and the seamstress of the store. Ayame designs the dresses, erotic as some or all of them may be. Vain and somewhat self-conscious, he is really a thoughtful person underneath his "selective" skin. He has gorgeous gold eyes and silver hair in a startling contrast to Yuki's violet and grey. His fear, coincidentally, is a fear of being totally alone. Much to Yuki's chagrin and surprise, he was actually the student body president in high school. When Ayame was young, he did not care for Yuki at all until he realized that when he got older, he would be totally alone without Yuki, spurring his new obsession to gaining Yuki's love shown in the series. Yuki has slowly started to accept Ayame as a brother.
