This story revolves around Kimihito and his household of monster-girls. The girls are introduced episodically, and the rest of the anime shows Kimihito and the girls' day-to-day lives. The girls are part of an International Exchange program to introduce the world of humans to the world of mythical monsters.
I would have liked to see more with the story, so I guess I'll have to see what the manga has in store. The anime kind of felt like a preview for the manga, since the episodes really only introduce the girls and don't go much beyond that. Still, the interactions in the anime give you a sense of each girl, how the world is reacting to the new monster population, and how Kimihito is coping with his new housemates. The anime did do a fair job explaining each girl's feelings towards the human population as a whole, but doesn't show them growing or changing those attitudes (Kimihito being the exception). One thing that wasn't answered was the Exchange part of the International Exchange. Were humans going to live with the monsters?
The animation is a little sloppy. For one, you never actually see the girls move, or at least, from the waist down. And when you do, it's not as crisp as the rest of the animation. An example would be Miia, who apparently flattens her tail when she moves, despite it being round any other time.
I particualrly liked the opening song "Fall in Love", and it was one of the few times I didn't immediately skip to the bulk of the show. However, I felt the ending wasn't memorable, even though it showcases the MON-squad.
The characters were interesting, although they fell easily into harem-trope categories that I have seen before, like air-head and aloof-noble types. The thing that set the girls apart, though, was the monster backgrounds that gave them those properties. Such as, Cerea was slightly aloof and nobel because that's how her entire race is. The strength of a harem anime, though, lies with it's protagnist, Kimihito. Unlike many other harem protagonists, Kimihito is competent and now shown to be a complete idiot. It's actually refreshing to see a protagonist that manages to build his harem by treating the girls like... actual people with feelings.
Overall, I liked the anime. I liked the interesting take on monster-girls, I liked Kimihito. Hell, I even liked the goofball screw-up that is Smith. I just wish the anime has been more expansive and not felt like a commercial for the manga.
