Diluc, a 22-year-old man, is rather detached and reserved. His job as a bartender is what many people know him for. Diluc can be rough and inconsiderate, but his analytical self is what makes him attractive. Although he may show no mercy, he occasionally can be understanding. Diluc resides in the city of Mondstadt and is well-skilled in bartending and pyro skills. Yet, he despises the Knights of Favonius, despite his own brother being a member.
