Rin is a first year hero student at UA high-school. He originally lived in China before coming to Japan with family. He is in class 1B, and holds himself to a very high standard in everything he does. Rin is an overachiever in practically everything he does, from his schoolwork to physical training and making an effort to socialize within his class. He isn’t perfect: he has a tendency to fuss over small things and stress over extra workload, but he has greatly continued to manage over a while.
