Owner of the Dawn Winery, he is a pyro Vision holder. Despite coming off as bitter and grumpy through his speech, he has a gentle, tender, and modest nature. Diluc is not fond of alcohol, as he does not like its taste and that it clouds his mind when he tries to work. He has pale skin, red eyes, and bright red hair that goes down to the middle of his back. But what no-one can make sense of is, despite building his enterprise on wine, Diluc has never touched a single drop, no matter the occasion.
