I'm obsessed you say? Well I guess I am. Here's another waifu I would like to add go my harem :3
Princess Yona (Akatsuki no Yona)
Now princess yona started out as a pampered, sheltered princess. But oh boy does she become such a strong matured woman.
Yona is definitely beautiful and even more son with her red hair. I love how she matures over the course of a few days after her father was murdered. She is affected by her experiences and when she realizes she's only being a burden to Hak by being defenseless she decides she's going to become strong and fight back.
I really admire her kindness and selflessness because she could very well stay with the wind tribe and live a safe and peaceful life but she decides to leave in order to protect them even though she's putting herself at risk. I really like how she's thinking of others and not just herself.
