Rumors tell of a Stony Cat statue that grants a special wish: it will take one of your disliked personality traits and give it to someone in need. Two students arrive at the Stony Cat eager to make a change – Youto, an unabashed pervert, wishes to remove his façade and be able to speak his true feelings, while Tsukiko desires to hide her expressions and be more like an adult. However, little did the pair know that their prayers would be answered in unexpected ways – Youto begins to speak the full, embarrassing truth with brutal honesty, and Tsukiko becomes visually stoic, unable to smile, laugh or cry! To make matters worse, Youto soon runs afoul of the beautiful school idol Azusa, the girl who inherited his unwanted façade. Together, the three slowly become friends while Youto and Tsukiko try to regain what they've lost.
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" shares the same premise, young boy geting involved with a cat statue resulting in obtaining supernatural abilities. In Nyan Koi the male lead need to help out 100 cats in trouble to get rid of the curse. Of course he also has to juggle his huge harem. While "Hentai Ouji to Warawanai Neko" has bit more moe and fanservice, "Nyan Koi" focuses more on the comedy aspect.
These two are definitely similar in story and in light comedic atmosphere. A cat god statue, strange curses, and a harem of girls surrounding the main male character make up the substance of the plot. If you like one, check out the other.
After being turned down by his unrequited crush, Hachiman Hikigaya is determined to live out the rest of his high school life single and socially tuned out to avoid the folly of youth. But Hachiman's resolve is lacking compared to his guidance counselor, a woman determined to change the boy's ways. So, much to his dismay, Hachiman is soon forced to reach out to those around him by joining a club dedicated to serving others. Alongside the cold, but beautiful club president Yukino, eager Yui, and other new friends, Hachiman will try to stomach his new volunteer work and survive his ultimate fear: being involved in a typical high school romantic comedy.
If you liked Yahari Ore no Seishun Love Come wa Machigatteiru or Hentai Ouji to Warawanai Neko then there's a good chance that you would like the other. Both of them are harem-type animes with a lot of humor thrown in. They also focus on only a couple of girls so it's easier to keep track of them. The MC in both is an outcast of sorts, who doesn't have top notch social skills (a pervert in one and an anti-social kid in the other). Despite that they end up having to help people and make new friends along the way.
Both are about a guy with a social issue, in one he is a pervert where as in the other he is anti social. In either series hilarity ensues as each of the main characters navigate through their high school days with their unique personalities.
On an island where cherry blossoms bloom all year-round, love seems to always be in the air. It is in this magical atmosphere that Asakura Junnichi lives, and when he dreams he travels to the dreams of others, rather than have any of his own. In everyday high-school life, he is accompanied by his adopted sister, Nemu, and an eclectic group of friends including a j-pop idol-in-the-making and a girl they knew from their childhood. Promises, and magic, and love -- Junnichi seems to dream about every girl he knows, but which girl dreams of him...?
Both of these romance anime are about a wish-granting tree/cat, with brownhaired and blonde girls central to the plot. As the male protagonist becomes involved in wishes, he meets even more girls as they, too, fall in love with the guy. However, while most of the time the characters are quite carefree, the plot always thickens whenever the wishing cat/sakura goes out of control, causing problems for the cast.
At Yamaboshi High, joining a school club is required, so when Himeko, Iori, Taichi, Yoshifumi and Yui couldn't find a suitable choice, they decided to create their own: the School Culture Club! Together, they pass the days meeting and coming up with topics for the group's newspaper – that is, until one day, Yoshifumi and Yui proclaim that they switched bodies last night! Soon after, all five members of the gang find themselves inadvertently swapping at random, with no end in sight. What, or who, caused this supernatural phenomenon?
In both of these anime, a group of high school friends gets involved with strange powers, like bodyswitching and wishes coming true. Kokoro Connect is more dramatic, and Hentai Ouji more comedic, but if you like the "high school drama with a twist" setting of one show, you might like the other.
