I have no idea what im looking for

[Kaasman]

Well its hard to describe what im looking for i have several tastes

First is

1: School / harem ( nerdy guy gets all the girls)

2:Some guy gets to live in with alot of girls and alot of awkward moments happen ( love hina style)

3: Some girl loves a guy for no appareant reason and all of the sudden alot of girls love him ( green green style) i know it fits 1 but its different

4: Series like death note where you have no clue whats going on and you are quessing for a few hours and then you found out what his plan was.\

5:Naruto love the serie its the first serie i ever watched its so much fun because of the difference in worlds

I would prefer if you tell wich one your recommondation goes to

Now my list of anime i already watched

naruto : just loved it
One piece : the leader is a retard whats more fun
Dragonball : fun but nothing special
Love hina : Awesome one

[Skyfall]

For the harem part...:

Shuffle!
Da Capo (both seasons)
Girls Bravo (both seasons) (really ecchi)
Magikano (lots of whacky humor)
Amaenaide yo! (both seasons)
Tokimeki Memorial: Only Love

Assuming you don't mind love triangles instead of a harem:
Canvas 2
Gft ~Eternal Rainbow~
Kanon (this is in a league of its own)
Lamune (pretty much straight forward romance between 2 people)
Suzuka

2 short and excellent series:
Iriya no Sora, UFO no Natsu
Hanbun no Tsuki ga Noboru Sora

For the mystery type of shows...
Higurashi no Naku Koro ni - horror/mystery. My 2nd favorite anime.
Ghost Hunt - mystery/horror(?)
Fantastic Children - adventure/mystery/SciFi
Noein - SciFi/Action

[Kaasman]

all the ecchi you recommended me i watched just forgot to put it in:P

[miaka]

Fatakoi/futakoi alternative
kage kara mamoru - nerd type but all girls love him
code geass - mystery/mecha... somewhat similar with death note
current series... Nagasarete Airantou

shonen jump series....
gintama - comedy/samurai
D.Gray-man- action
Busou Renkin - action

[ibreatheanime]

for a nerdy guy surronded by girls how about Negima???

[Kaasman]

negime i watched like first 10 eps and didnt like it at all i just watched Futakoi and it was fun but i prefer scenes with not 10 eps of waiting for a kiss but in like
Kimi Ga Nozomu Eien where they fuck like on what the 3 ep so i dont feel like waiting for a kiss but get into the realy story

[Kaasman]

well just finished watching shuffle + memories and i have too say that just scored on my top 3 list

[WanderingKnight]

If you watched the old series of Negima, no wonder why it looked like shit. I've had problems stomaching though I love the manga. Watch the new Negima, which is a lot better (but which is some sort of mega-spin off of the storyline).
