Diluc is a redhaired, fatherly man. In his mid 40s, and sees anyone younger than 21 as a kid.

He has a natural instinct to protect and care for vulnerable people, which lead him to be a knight when he was younger. He quit the knights a few years ago, and works as a vigilante now.

Though he disagrees with the knights a lot, he doesn't doubt their intelligence and vital role in protecting Mondstadt
