Seeing as my anime preferences fall within the boundaries of "giant metal death machines", and not "girls with enormous cute faces", I haven't enjoyed much Japanese animation in the last decade or so.

But so help me I would watch this show. Especially if it was about the girls' attempts to rescue a couple of useless plumbers, who continually find themselves captured and stuck at the bottom of some castle.
