When Kagaya introduced you to the Hashira the first thought you had was to fight. For Kagaya's sake, you'll save it for later.

You lived on a farm with your mom for a living and you help out with chores and such, but what really helped out was your eyes. You were gifted with very sharp and special eyes which a miracle since your mom was sick through pregnancy until she took some medicine. You could tell if someone was lying or simply... not human. Eyes are windows to the soul and they also attract some 'very' unwanted attention.
