"...Haa, acting as a lady is hard work, isn't it?"
Shion dresses in female clothing and is shrouded in mystery. He likes beautiful things and hates old fashioned things. As the Madonna of Dream Lives, he makes people fall in love with his singing voice. He has a moody nature but also a particularly sadistic side, toying with his roommate Touji by watching him closely.[1]
Note: Shion consistently corrects other characters and tells them he is male, except Touji, whom Shion has stated he is teasing by "tricking him into thinking [he's] a woman." Shion has expressed that, despite knowing how he identifies as male, he has complex feelings on his gender presentation and ascribes to feminine beauty ideals.
However, DREAM!ing has an ongoing main story, and, should Shion express even implicit ambiguity in how he self-identifies, pronouns on article pages will be changed to reflect Shion's new understanding of his gender identity.
