fellow tiny/normal character that would be demolished in battle, check

Yona also fits the been through war thing and she's a displaced princess so she didn't grow UP poor but she definitely knows what it's like to be living in a forest eating bugs when things get tight.

Basically I just love Steve and I think Yona would fall into this desire to protect him while also seeing he definitely has it in him to get stronger. Maybe they can work on that together!
