Whats your favorite loli.Mine is Yui from SAO.

IDK man, I think there's way too many good lolis out there to have a favourite.

Though recently I'd have to say there's Roka from D-Frag and Suzu from SYD.

Riccotta Elmar from Dog Days , Tsukuru Kagaku from R-15 , Sendo Yukari from Rosario to Vampire and Hanyuu from Higurashi no Naku Koro Ni

rook from high school DxD

Len/White Len from Tsukihime/Melty Blood.

Arisa Takanomiya From Onii-chan Dakedo Ai Sae Areba Kankeinai yo ne

there are A LOT of very very awesome ones, most likely I like Koneko from highschool DxD the most but there are a few that come very close to her.

"You don't simply have one favourite loli" is what goes for me. It is very hard.
Some of my favourites though, are:
-Koneko Toujou (High School DxD)
-Ui (Sunday Without God)
-Mashiro Mitsumine (Engaged to the Unidentified)
-Nymph (Sora no Otoshimono)
-Yoshino (Date A Live)

sora from yosuga no sora, koneko form hsDxD, ako from kiss x sis. can´t say only one there still is some favorites beside these 3

Tina Sprout from Black Bullet
