This is Runningwind. She was known for her swiftness, until her right forepaw twisted after tripping into a drop-off while patrolling. Everyone had sympathy on her, and she assured them it was all right, and told them to be happy. She never complained. She received her warrior name to honor her prior wind-like speed and spirit.
The song is Kaze Ni Naru (Become the Wind) by Ayano Tsuji. I hope the lineart isn't changed too much.
