Daisuke Hirakawa Because of what he was, sickly and in bad health (though it was never revealed as to what exactly was wrong), his parents hypnotized him into protecting his secret. "Close your eyes and cover your mouth; you'll forget your true form." Taken in by the Fujiwaras (both Shiro's adopted mother and father's names have never been released), he was adopted as their son. Shiro never knew of his birth parents, the only hint to his secret was his higher body temperature, which led Yonekuni to him. Living somewhat a double life, the only male "friend" that Yonekuni had and, at night, the lover Yonekuni visited when it rained or he became "sickly." It was soon that his secret, both of them, were revealed: Yonekuni awaking to what he thought was a dream, only to find out that he had been making his way to Shiro's place and sleeping with him, the secret he never knew about until Yonekuni willingly and full-heartedly slept with him; the spell that his parents placed on him was broken. From there, Shiro was able to tell as much as he knew to Yonekuni and that started his lessons with the Madarame family. ==Media==
