Harem anime, also known as the harem genre or reverse-harems, is an old yet popular concept of Japanese animation where the main protagonist is surrounded by multiple love interests. This type of fiction often involves romance and comedy but can be mixed with ecchi because it’s a relatively predictable setting (awkward moments are inevitable).
The main character is usually male. If the protagonist is female with multiple suitors, then it’s a reverse harem anime. Since this genre has been popular lately and many people have become fans of these titles, we compiled the best harem anime so far.

But unfortunately for poor little Ayumu, there’s no running away from these funny moments in this harem series.
This is a not so typical harem anime but a psychological anime harem series with an over-stylized title. Takumi Nishijou is a schizophrenic hikikomori, or recluse, who doesn’t want to leave his house because he thinks that the world outside of it isn’t real and has made him paranoid as well. He’s forced into the real world by a series of strange events and visions surrounding a recent string of murders. Takumi finds himself surrounded by several girls who have some connection to incidents, but he can’t tell what is real.
The Sekirei are aliens who visit Earth to find a master. Thanks to the rare “kiss contract,” only one kiss are enough for these extraterrestrial beings, which unlocks their special power and full potential making them stronger than regular humans under pressure-filled situations. But this isn’t some super power just anyone can have—it’s an exclusive ability bestowed upon those with certain genetic mutations like Minato Sahashi. And while he may be only 19 who failed his college entrance exam twice but, his skills as the youngest of all other masters have made him more powerful than any others on Earth!
This is a must-watch harem comedy ecchi anime for harem fans for the storyline and occasional fan service moments.
