The anime is centered around "Tsuzuki Takumi", and the main characters are introduced during the first three episodes (Takumi is the only male main character). Serizawa Fumino (Takumi's Childhood friend), Kiriya Nozomi (a "stray cat-girl"), and Unemori Chise are the main characters, which are introduced in the first two episodes. All three commonly have contradicting opinions and actions, and Unemori Chise gets in quarrels with Fumino quite often. It becomes apparent that the 3 of them fall for Takumi by the end of the first season, for the kindness and way he is (Season 2 is guaranteed, based on Manga to Anime comparisons). The dialogue isvery humorous, and the situations that Takumi is put in because of the three females makes you chuckle, regardless of how well you can suppress it. The scenes amplify the effect, since Mayoi Neko Overrun is an ecchi type anime. Episode 4 contains the most embarrassing scenes for the characters, and the way it is shown really makes you laugh.

No real battles, similar to the anime Spice and Wolf, but with a Cat-Girl rather than a Wolf-Girl (although the main character describes Fumiyo, his childhood friend, as a Wolf).

Animations are decent, could be slightly smoother and less... artifact-filled, and they could have extended the amount of time it took to go through the Season. Episodes 1-3 seem okay, as they are all for getting to know all the main characters, but it begins to feel rushed and compressed from the Manga afterwards. The main problems would be in the anime progression. The first three episodes were good. After that though, everything seems to go a bit off-topic. Randomness is very high, and you could begin to question why it was written this way.

The sound and art would be the strongest points of the anime, in my opinion, but they could have used certain soundtracks for different scenes, as I feel that some of them aren't exactly appropriate for the scenes. Animation is smooth, but you can notice that they cut some corners around the last few episodes.

Overall, I rate it 8 out of 10. The concept, artwork, and sound are good, but the execution of the plot/storyline was not great at all. Suggested for comedy fans.
