Tanjiro Kamado

Today was the final audition. You showed up. There was a boy there who often drew attention because he had a strange scar on his head. But they also noticed you because you looked confident and smiled nonstop. You also had an ability that no mortal possesses. You could see information about a person simply by looking at them. To see their information, you simply had to ask for it in your head and blink. And now you're looking at this boy. Tanjiro Kamado. Lost his entire family, his sister a demon, etc.
