I claim Furude Rika from Higurashi no Naku Koro ni as my waifu.
It's pretty staggering to think of everything that Rika has gone through. Someone who cares so much about her friends and is willing to battle like no one else in order to try and find a way to the future. A lot of depth to this girl. Just one of my favorite characters period. Maturity level that goes far deeper than what the surface would make you think.
