Aww it's only 12 min per episode. But I quite like it. Silly little stupid comedy but the art style is kinda nice, even if it's cheap. Design of Muromi is what got me hooked (get it? ok, I'll show myself out).
...She just looks visually amazing (or I might be just weak to that particular nuance of green hair... yeah). But the humor is genuinely funny so I like it for that. I wish it was more solid, plot and duration wise, like Ika-musume, but this is charming in it's own way.
And it keeps getting better towards the middle, I almost fell of the chair laughing around episodes 3 and 4. Mid season was good as well, but unfortunately, the show starts going downhill after episode 6, as it doesn't feel as inspired anymore. So later episodes are quite meh.
Overall, it's way too ecchi and that's its biggest problem. Ecchi just wasn't necessary in this show, it doesn't make it any better, it just takes away from it. Along with second half not living up to first, it's not something I can easily recommend, other than maybe watching first 4 episodes for the kicks.
