In her younger years, Mirajane was known as "The Demon" (魔人 Majin), and before Lisanna's pseudo-death, she used to be a very feared person, infamous amongst guilds and criminals alike. She dressed in a punk-gothic style, and was rather temperamental and bad-mouthed everyone, especially Erza, whom she had quite a rivalry with from when they were kids. Despite this, she had initially been very withdrawn and held reservations about who she was due to her Demon-like powers.
