Mirajane?

"well i know someone who would probably leave you but you better not get any funny ideas while you're with her" Erza says "who are you talking about?" Naruto asks "Mirajane she's one of the better known members of the guild and she's just sitting around helping people in the guild she'd be fine if you owned her after she's done working with me and she's really having a girls' night out tonight so I I can ask her."
