BEST PERVERTED ROMANCE ANIME: Sakurasou No Pet Na Kanojo (The Pet Girl Of Sakurasou)

Yes, from the title, this is a perverted yet romantic anime. You literally see episodes of female characters naked, running around like it's the most natural thing to do. This anime is actually pretty funny but it's not to the point where it's too sexual and uncomfortable to watch.

Plot:
Sakura Dormitory is a dorm of the high school affiliated with Suimei University of the Arts (often shortened as Suiko), which hosts the strangest, most trouble-making students. After being kicked out of the normal dorm for keeping a stray cat, Sorata Kanda moves into Sakura Dormitory. As he starts to get used to the life in the dorm, Mashiro Shiina, a world famous artist who cannot even take care of her daily life, moves in. Sorata is forced to become Mashiro's handler. The story is about their daily lives as well as mental growth.

This is my AMV, which pretty much sums up the anime. Enjoy!

The song I used is Enchanted by Owl City.

The type of romance between the male and female protagonist is just too sweet and adorable.
