just enough to enjoy after watching action / sad anime, it's kinda refreshing because i never watch Monster Musume no Iru Nichijou, tho people will deemed it will be the same with that series, thought the differences will be the MC's profession, for me it was pretty much enjoyable even tho it mostly go to the ecchi sides xD anyway not a bad anime, especially if you get bored or don't anything to watch anymore xD tho i think there's a lot of better choice :) the ending song pretty good to be honest, and the 3D also pretty smooth, well, anyway, like i saidbefore, it was pretty enjoyable, please try to watch it if you have nothing to watch xD
