Azumi is a male transvestite (one who dresses as a woman) who works for Saigou Tokumori, at the kamakko club (かまっ娘倶楽部). Currently, Azumi is dating Juurouta. He is also known as "Agomi" because of his prominent chin, "ago" being the Japanese term for chin.
Azumi has a permanent stubble on her face like many of the okama at Saigo's bar. Because of her prominent chin, she's often called 'Agomi'. Her orange hair is cut in a bob and she wears a purple female kimono.
Sometime after the Four Devas arc, she replaced Saigo as one of the 'four devas'.
