Post a character who toi didn't like at first, but they grew on you.

Sakura in Naruto comes to mind,she really did grow on me,and now she's one of my favori characters!

Sayaka Maizono. I used to absolutely despise her. Now she's one of my favori characters!

This dude. From orange Marmalade. It's an amazing manhwa, I couldn't think of any from anime.

I have many, but I'll go with Jean Kirschtein from Attack On Titan. :)

There are quite a few, but I will go with Panty Anarchy from Panty&Stocking with Garterbelt, this time. ^ ^

gin Ichimaru from Bleach. I used to his was creepy and annoying, but now I'm a gin fangirl!

Euphemia li Britannia from Code Geass. She started off annoying when she first appeared, but she started to grew on me on episode 18.

I started liking itachi after knowing what he went through and now I he is one of my favori character in Naruto shippuden!!

Aomine Daiki from Kuroko no Basket.
At first I couldn't stand him. The way he acted, talked and all made me wish that I could coup de poing him. :D But the plus I watched the animé and slowly gotten to know him better my opinion started to change (as did his character). Now he's one of my favorite. :)

I used to really dislike Grell (Black Butler), but he later grew on to me and became my seconde favourite Black Butler character.

Usopp:D l’amour him even plus now^^

Ami Kawashima from Toradora!!! At first I saw her as an arrogant whore who only cared about her looks.Then,I started to like her because she helped Taiga realize that she had feelings for Ryuuji even though she also liked him.

I thought Kyoya was kinda self-centered and douchey at first, but I grew to l’amour him.

Please don't kill me. (>////<) I use to hate Kuroko Tetsuya from Kuroko no Basuke. I thought "Ahhh. He's so mainstream. Always winning. But he's taking things for granted as he used to be from the MiraGen." But after watching finished Season 1 and lire the ongoing manga, I realised how much he worked for his goal and his traumatic past. In the end, he became one of my favourite characters. ^ _ ^

L from Death Note. I eventually grew to like him after I watched plus episodes of Death Note.

Light Yagami from Death Note. I always had a certain degree of respect for his intelligence, but after THAT incident (Ep. 25), I despised him (not as much as Misa, but I still had issues). Now, he's my favori Death Note character and my main cosplay.

zero from vampire knight.... i didnt like him for like 3 to 4 episodes but then now i like him soooo much!!!!
