Hmm
Probably Norway from Hetalia. That really suits my 'in real life' personality. Stoic, boring, and sarcastic. Also will not hesitate to kick obnoxious people's butts.
Pinkie Pie from MLP FiM has, on occasion, been a remarkably relatable character for me. An example would be the episode "Party of One". She is almost exactly parallel to me in that episode, aside from the detail about when she snaps talking to inanimate objects. I won't do that. lol
I think I'm most like Yamato from Ore Monogatari. Kind to others, loves baking, I'm also petite and a redhead but wait there's more! I was also born premature like she was. I weighted less then her when I was born though...
For sure am Umaru. I mean she loves video games and manga. Loves to snack and have a good lazy time. But is super girly at the same time and tries to hide her true interests.
I never related more to someone.
