As of right now only once in the beginning Taiga-san was my favorite but now Ami-chan is my favorite character.

^ Same thing happened with me. Almost immediately after Ami was introduced she became my new favourite.

I will never change my favorite character from Taiga-san!! ^_^ She's such a bad a##!!!

Taiga has always been my favorite.

Yeah, my original favorite was actually Taiga but then I started to appreciate Ami's character much more then I had originally.

It used to be Ami, now it's Minori.

Though I love all the characters for their own qualities, Taiga has been and always will be my favorite character.
Even characters like Kanou appealed to me in a way. Kitamura was underrated in my opinion. He went up on stage and declared his love for Kanou in front of the entire school! It takes a pair to do that!
Minorin was awesome too. Especially after letting Taiga have Ryuuji and her quote, " I won't let anyone else decide what makes me happy! "
Ami was great in a practically indescribable way to me, and Ryuuji, though he was basically a mix of Kenta Usui and Susanoo, was also great. There is so much to love about this show and it's characters, and that's what makes it my third favorite anime ♥

Taiga Forever!!!
Reason: She's the queen of Tsundere!!
Why not the others:
Ami: Because she's a Bit--
Minorin: Too hyper
Kitamura: Too serious
Ryuji: He's cool.. But not as awesome as Taiga!!
