Diluc

Diluc was once a perfect young man, dedicated to his work in the Ordo Favonius. After his father's untimely death as a result of using Illusion, and after Inspector Erok ordered Diluc to cover up the incident, his faith in the Ordo Favonius wavered, and he left the organization. Even after Erok was expelled from the Ordo Favonius for treason, Diluc still harbors resentment towards them. He claims the knights take too long to do their job, though he still appreciates those who try, like Lisa and Jean.

When he was a member of the Order, he adored his father, Crepus. When his father praised him, it made him happier than fame or anything else, and Crepus told Diluc to be true to his duty. After his father's death, he restrained himself. Despite the bitterness and irritation that linger in his speech, he has a gentle, tender, and humble nature. As a child, Diluc was carefree and happy, unlike his current self.

Despite being the owner of Mondstadt's largest winery, Diluc dislikes alcohol, disliking its taste and the way it clouds his judgment when he's trying to work. He prefers non-alcoholic drinks like grape juice and apple cider, which he ordered after returning to Mondstadt. However, not everyone seems to know this, likely due to his status as the owner of Mondstadt's largest winery. He's even surprised to learn that Diona also hates alcohol, as he initially thought he was the only bartender in Mondstadt who didn't like it. He also tends to get rid of things he no longer needs, such as his father's private residence.

Diluc is a tall, handsome man with fair skin, red eyes, and bright red hair that falls to the middle of his back.
