Having lived in the same orphanage as children, Takumi Tsuzuki and Fumino Serizawa grew up together and remain fast friends. Now living and working at a bakery, Takumi does his best to prevent catastrophe, particularly when the clumsy Otome is in the kitchen! He attends school with Fumino and is still the only person capable of reading through her baffling habit of hiding her emotions by saying exactly the opposite to what she means. However, the arrival on the scene of enigmatic catgirl Nozomi may force Fumino to be more honest with her feelings than she is used to - or perhaps even able to. This, along with a host of crazy friends and associates such as the stuck-up Chise and the otaku Ieyasu, ensures that there is rarely a dull moment in their lives!
Everyone around Kousaka seems to adore cats, but due to his allergies the teen can’t stand them. So when he wakes up one day and can hear what every feline is saying, Kousaka is annoyed to say the least. His new “gift,” it seems, is the result of accidentally breaking an enshrined statue of a cat; and what’s worse, Kousaka must atone for his sin and appease the vengeful spirit by aiding one hundred kitties-in-distress, or become a furry feline himself! Now, amidst helping various cats with mundane and trivial issues, Kousaka must try to dispel the jinx and attempt to salvage his self-respect – not to mention his love life - along the way.
Nyan Koi! and Mayoi Neko Overrun! share the same crazy neko-nyaaa~ feeling, they make you wanna repeat 'Nya~' again and again, even more - they make you see cats everywhere. Both are shounen romance comedies, they made by the same studio - that's an important fact too. Oh, and don't forget about tsundere characters! ^^
Both are cat-based anime. These two are essentially romantic comedy harems but still hold their own when speaking about the romance and comedy departments separately. If you like yourself some nekos, dash to the other awaiting you to pick up.
Both have the protagonist set as a rather timid wishy-washy character with a ddep heart who is surrounded by characters who love cats. The only area the two differ in is the fact Nyan Koi's protagonist Junpei is allergic to cats which causes him various problems whilst Takumi loves cats.
While trying to protect a wooden relic, high school student Yuuri Mito summons the Goddess Kikuramikami no Hime in the form of a sweet, affectionate child; she begins to live with him, taking the name Mashiro. Yuuri promises to marry her when she grows up, which unfortunately for him happens overnight! However, they soon have bigger things to worry about, as the relic is accidentally destroyed, unleashing the Tayutai, a human-hating race of monsters. Along with Yuuri's childhood friend Ameri, his step-sister Yumina and Mifuyu - an honour student at Flawless Girls' Academy - Yuuri and Mashiro must step up to fight the Tayutai, protect the world, and even learn about underwear!
Both series are quite similar - boy X "adopted" mysterious girl, so he made his tsundere-like friend jealous. Another love competition has begun.
The lead female in each of these series is a cat girl, each of these series has a lot of harem antics, and some light comedy. If you enjoyed one series, you'll like the other.
They are both about an Animal-Girl (thou in mayoi neko overrun it isn't confirmed that she is a animal) combination being brought in the live of a boy, and they both come in the same school (again there is the difference that in tayutama this is only for a short while) and in both the anime the animal-girl falls in love with the main character (thou in tayutama it's more about the relationship and in neko overrun it's more... random) and last but not least, both are (or at least can be) very funny and worth your time (if you don't mind the Ecchi)
When Hayate was young, Santa appeared in a dream and told him that if he worked hard, he’d be rewarded. Thus, with an unbreakable will, the unfortunate Hayate has struggled through life holding onto that belief. In the present, his parents are lazy and unemployed, forcing Hayate to work several jobs to pay the bills. As if things couldn’t get worse, Hayate’s parents then run away, leaving him with an enormous debt and loan sharks on his tail! Naturally, the best solution to find money fast is… to kidnap someone?! A girl named Nagi is the target, but due to an unfortunate miscommunication, she believes Hayate has proposed to her and falls for him hard. After Nagi paid off his debt, Hayate must now work as her butler in order to repay her; but first, he must adapt to her wacky world!
Both, Mayoi Neko Overrun! and Hayate no Gotoku have lots of similarities.
Personalities of the main characters are alike. For example gentle, weak-looking protagonist, who despite his look will always find a way to help someone in need. In Mayoi Neko it's Takumi, and in the Combat Butler it's Hayate;
a princes-like girl, who posses enormous amount of money, but is really stubborn and noisy - Nagi from Hayate no Gotoku, and Chise from Mayoi Neko. Other characters have similar personalities too, but I think 2 examples are enuogh.
The second thing that makes these animes look similiar are its jokes.
The third similarity is that there are a lot of refferences to the otaku life and other anime.
These 3 reasons should be enough to make you want watch either one of them if you haven't yet. Mayoi Neko Overrun isn't as hilarious as Hayate no Gotoku, but it's worth trying, because there is always a chance, that You will like it.
Each series focuses around a harem and involves a large amount of comedy and allusions to other anime. Further, each series focuses on a guy oblivious to the fact that the girls around him all like him and have several other similar characters floating around.
Mikuriya Jin makes a woodcarving from the remains of a guardian tree, but he gets much more than he bargained for when girl materializes from the statue! Her name is Nagi, the troublesome and at times violent deity of the land; and with nowhere to go, she announces that she will stay with Jin. Now, with Jin’s help and a magical girl wand purchased at the local convenience store, Nagi aims to exorcise the impurities that are infecting the land. Though when the sacred tree is finally uprooted, it is only a matter of time before her powers will diminish; thus, a new object of worship is required, and what better object than Nagi herself! However, obtaining your goal of becoming a popular idol is not so straightforward, especially when you have to compete with your sister, who is unwilling to share her fan base and plans to sabotage you at every step!
Each series focuses on a guy, finding an odd girl, and a lot of other girls that already have feelings for him. Apart from that, many of the females in each series have a similar back story and personality, and each series is a comedy that has a lot to do with otakuism.
Seeking a cure for his depraved masochism, Taro Sado approaches the Second Volunteer Club on the recommendation of his best friend, Tatsukichi. There he finds the help of the violent but kind Mio Isurugi who promises to beat the masochism out of him by any means necessary. Will Taro be able to survive the assaults of this upperclassman, the overly-affectionate attentions of his mother and sister, and still lead a normal school life? Unlikely. But will he get over his perverse fetish? He sure hopes so.
The main similarity with both anime is that the girls all like the main guy, but the guy is clueless about it. With some not honest with their feelings and others very open about it, it is very hard for even the viewers to choose who he should be with. Also, another similarity is that the main character keeps getting hit by the tsundere girl, only in MM! he enjoys it more.
