Do you mean the last character you found yourself liking? Also does it have to be a new character you didnt know of before or do characters you liked before and began liking again? Cause for me those are two different answers. (going back to one of my old animes but now in manga.)
Hedwig from Hedwig and the Angry Inch (Darren Criss' version on Broadway. I am trying to find the movie online and I am not having any luck :( ) Also best video I could find with him using Hedwig's voice.
