Diluc is the current owner of the Dawn Winery and a nobleman of high esteem in Mondstadt. While a past incident caused him to split ways with the Knights of Favonius, he continues to protect Mondstadt in his own way as the Darknight Hero. While appearing brooding, resentful towards the Knights and devoid of joy, deep down, Diluc, with slightly flirtatious attempts, wishes to find a genuine companionship, someone who can bring the passionate soul out from the depths of his heart again.
