7) The Pervert Prince and the Stony Cat
You can guess by the name of this anime that it is 18+ series. Who is the biggest pervert at school? I vote for Yōto Yokodera, a second-year high school student. He finds out there is a statue called “Stony Cat” that can grant you a wish that will come true.
He and a girl named Tsukiko Tsutsukakushi wish to change their personalities but after the stony cat grants it, they regret asking for it. The Pervert Prince and the Stony Cat anime has several of the funniest scenes in anime.
6) High School of the Dead
If you like zombies film you will love this anime. A disease making people into zombies and a group of high school students want to survive it. A student witnesses a zombie breakout in his own high school and gets along with a weapon-maniac, the girl who was his crush, a master fighter, and the school nurse. this group make a run for it on this Sexy Harem Anime
5) Heaven’s Lost Property
Tomoki Sakurai is a perverted teenage boy whose motto is “Peace and quiet are the best” until an angel falls from the sky or should I say “a winged female humanoid named Ikaros” and become his servant.
4) Rosario + Vampire
What would you do if you unknowingly being sent to a school for monsters disguised as humans? well, this is exactly what happened to Tsukune Aono. Tsukune Aono doesn’t run away, he meets the vampire Moka and stays in the school of monsters. In my opinion Rosario one of the best harem anime to see.
