[mzie chan]

Futari no Ecchi (it's not hentai)

but in anime: Tenjou Tenge ... (it's manga is.. i think, a hentai)

[rin08]

so far to those that i have watched , the ecchiest is tenjo tenge,,,

[GMSieghart]

i will go with Queen's Blade and Tenjou Tengge!! :D! ECCHI!! is the Best!! :D

[inubazh11]

KissXSis, and Yosuga no Sora. Its like borderline H_

[Bolero]

If only Koe de Oshigoto! is updating :'(

[DarkQwaser]

kissxsis and yosuga no sora as far as i know from now...

[HellGirl134]

I think:
Rosario+Vampire
Highschool of the Dead
Yosuga no Sora
Freezing
Aki-Sora
School Days

[MRraindrop]

KissXSis hands down i even think it's not considered an anime anymoar more like a softcore hentai ^_^

[akira sendo]

KissXsis,Yosuga no sora,Highschool days. I was shock really in yosuga no sora in the end. O.o

[nataku411]

Probably Hanaukyo Maid Tai.

[PolPunisher]

I totally agree with MRraindrop that KissXsis is by fare the most ecchiest anime series that I have ever seen. OMG!!!

[DarkDenizen]

Probably KissXSis, Kanokon, Sekirei and Queen's Blade...are the most Ecchiest

[Vonny strife]

queens blade....awesome as ever :DDDDDDDDDDDDDDDDD

[Anfie]

I don't like ecchi >_<

[tetsuo]

Queen's Blade is just the ecchiest hands down, it's just nipples away from hentai.
