Inori Yuzuriha: Guilty Crown
She is sexy throughout the entire series and deserves to mentioned for it.
Irina Jelavić: Assassination Classroom
She is a freelance assassin whose specialty is infiltration and she uses her body and charm to get her to her targets. I mean, look at a picture of her and it's pretty obvious why she's sexy.
Jibril: No Game No Life
She has the bust of course, but her pink hair and characteristic features (large eyes, halo, wings, even the outfit) bring out all her sexiness. It definitely helps to be masochistic and a bit overtly sexual as well. Basically, Jibril's exotic sexiness is what has her win out in my book.
Nico Robin: One Piece
I think Nico Robin is the best because she is a tall slender woman. She had a horrible past with no friends but still, she survived. She met the main characters and had a new life and isn't alone anymore. She likes to read and drink tea. She is very professional and is a archaeologist. She is the brains of the group and respects everyone. She also has a sexy appearance.
Pico: Boku no Pico
He's a pretty girl.
Shiro: No Game No Life
look at her
Taiga Aisaka: Toradora
Her small and petiteness make her have the sexy moe look.
Chocola, Vanilla, Coconut, Azuki: Nekopara
Mmmmmm dem nekoz, Mmmmm still nekoz, Mmmmm dat Liollie neko
Dio: JoJo's Bizzare Adventure
You thought this was an actual submission, But it was I Dio.
