After joining kimetsu academy, people started to realize your personality. Stoic and serious. You had an athletic body mixed with intelligence making you a straight A+ student. Good in P.E, never got in trouble, intelligent, it was almost unbelievable for a human to be so perfect. But obviously, your only bad thing was you never talked or had any friends. Just remained silent and mysterious. This caught people's interest.. you were so perfect yet so reserved..
