Yes, Yuzu chose to keep on skating after the earthquake and chase his dreams, but he did a bunch of ice shows for charity and he's always trying to give back to the community. He still feels very guilty about leaving.
If anything i can picture him as a Gryffindor: Brave, bold and sometimes they do stupid things fueled by a sense of duty and justice (skating while injured, and again, the incredible number of ice shows he skated at to raise money for 3.11).
