But then again, this is really just too obvious. She's such an Lookalike you could use her as a Reference/Stand-In for Fanart of an older, matured Mercury! No, seriously, she even has that single Ahoge ('Idiot Lock') at the top of her head!
P. S.: Geez... Is there ANY Screenshot of that Anime available which does NOT censor the 'Naughty Bits'?
