Ayumu is the daughter of the 5th Pro Hero (OC) called Flame-Bender, since he could Fire-Bend. Her Mother was a quirkless lady who takes care of the house and the family, she has a nice job that gets her a lot of money to help her family. Ayumu turned out like her father, becoming a Fire-Bender. But, she was gifted by spirts and the past Avatars, that gift was being the Second Avatar. She gets mentored by Korra, and they bond closer. Ayumu leaves China to go back to Japan, to let Korra be the Avatar again, even though Korra said it was okay, and so she could live with her father who is now the 3rd Pro-Hero.
