There's too many to list all on one page.
A few that i'd recommend though:
Ouran High School Host Club
Hayate X Blade
Occult Academy
Soul Eater
School Rumble
Gakuken Heaven
Lucky Star
Life
Seven of Seven
Full Metal Panic?
Maid Sama!
Shuffle!
They all vary from Shojo, to Shonen, Harem and reverse Harem, Action, fantasy, and mostly comedy.
School Rumble
Yes there is some, but the anime is not really focused in ballet. But the setting is in a ballet school. The name for this anime is Princess Tutu.
Some popular ecchi anime include "High School DxD," "To Love-Ru," "Monster Musume," "Prison School," and "Kiss x Sis." These anime often contain suggestive themes, fan-service, and light-hearted humor.
The anime series "School Days" has 12 episodes .
Never. Thet are not planning to put it in anime
High School of the Dead. It first came out in early 2010.
if what you are looking for is a funny anime show: school rumble^its AMAZING!!
I do not not exactly by what you mean by dirty anime, but I will try my best in answering your question. For really eechi and percerted anime, try this: Kanokon, KissxSis, School Days. For really messed up Anime, try: School Days (really messed up), Wlecome to the N.H.K. (Not that messed up). For a really gory, sad but romantic anime, try: Elfen Lied
hana-kimi and ouran high school host club
Anime and Manga: Gakuen Mokushiroku: High School Of The Dead
funimation has lots of anime, some of them you can find on youtube. one of my personal favorites was Ouran Highschool Host Club :)Type your answer here...
There are a lot of anime that have slight violence but not so much until you see all the internal organs... Some romantic and comedy anime where a guy chases a girl will show some violence including the guy nosebleeds or he say something wrong and get beats up by girl. They are quite cute actually...There are probably some non-violent ones but usually they are not so popular. Try sports anime,Recomand you some anime (contain some little violence)baka to test (school life/studies)eyeshield 21 (sports)
