A member of Millennium known by the alias "Voice of Justice" (Justice Song), who fights demons by summoning various heavy firearms and wearing a black leather coat. Characterized by jagged teeth and jade-colored, medium-length hair. She scatters demons by firing her pistols without hesitation. She has a tomboyish personality but is weak to pressure. Possessing high physical ability, she is also skilled in mid-air combat to some extent using wires. Her speech is masculine, but her first person is "I" (polite/neutral). She laughs with a "Kishishi" and fires her pistols with no telegraphing motion. Scary. It's questionable if she's actually raising a "voice of justice." However, she takes her mission to defeat and eradicate demons more seriously than anyone else.
