==Summary==
;Legend of the Darknight Hero
Inside Angel's Share in the City of Mondstadt, Charles tells the Traveler and Paimon a tale of rumors about a certain Darknight Hero have been circulating around Mondstadt. Intrigued by this, they set out to figure out his identity.
They inquire about the Darknight Hero from the townsfolk, and put together that the Darknight Hero is a wealthy, Vision-wielding vigilante who is not affiliated with the Knights of Favonius. Having learned that he acts around nighttime, they waited and later heard a ruckus at the north alley. Arriving at the site, they find the Darknight Hero himself, Diluc, fighting an Abyss Mage who he easily kills. Diluc is surprised by the Traveler and Paimon's sudden appearance, admitting that he had already planned his route beforehand to avoid the guards. He urges them not to inform the Knights of his identity as the Darknight Hero and quickly leaves. Huffman arrives a minute late to the scene.

;Darknight Hero's Crisis
Huffman has informed the Traveler that the Abyss Order is waging war against the Darknight Hero through a letter they obtained. However, parts of the letter are put in an indeterminate cipher. Diluc, who heard the challenge from his Winery, suggests that he needs information from the Abyss Order to translate it, having located a stronghold. The two infiltrate the stronghold and confront Landrich, a Hydro Abyss Mage and quickly defeat it. Landrich initially refuses to disclose any information, prompting Diluc to use his Vision and tortures the mage with Burning Hand. It quickly loses its resistance and tells them that the attack is intended tomorrow night.
Returning to the city, the pair meet up with Huffman, who tells them that they intend to discover the Darknight Hero's true identity to monitor their actions, as it will be a threat to the Knights if left unchecked. Kaeya then walks in and tells Huffman to keep close tabs on Diluc, having been tipped off that he had been working somewhat often at the tavern. Huffman is surprised by the thought but nonetheless complies with Kaeya's order.

;Darknight Hero's Alibi
The pair head to the winery, where Diluc is not surprised by Kaeya's actions, but asks them to bring him some Mist Flower Corolla in the nearby area. After returning with some, Diluc hands them over to Connor. He tells the two that his staff was experimenting with the flowers to increase sales, but it instead attracted numerous slimes because of the elemental energy the flowers contained. Diluc then realized that he could use this to cause some trouble, and has the Traveler set a small amount on the ground. Not long after, some slimes converge onto the winery, which they all clear out before they could cause some havoc.
Diluc then explains that he will tackle the Abyss Order's horde by himself, while the Traveler and Paimon head to the tavern to ensure that Huffman does not suspect him as the Darknight Hero. They meet up with Huffman and Paimon prepares to order some drinks, only to have no Mora on her. Huffman tries to pay for her drink, but Paimon declines the offer as part of the plan.
Placing the bait and returning to the tavern, Diluc prepares Huffman's Dandelion Wine when a guard comes in and tells him a massive amount of slimes are attacking. Huffman is surprised by the sudden appearance of the slimes and that it was the Abyss Order's secret weapon. Initially intending to monitor Diluc, Diluc shames him into assisting in the city's defense. The three then head to the other gate where Diluc effortlessly wipes the horde out, returning to the tavern before Huffman could arrive.
Huffman returns and notices the Traveler is unusually exhausted, becoming suspicious. He then asks the other patrons if Diluc had left, but they all tell him no. Huffman leaves the tavern, skeptical but does not pry further. Diluc reveals that all of the "patrons" in the bar are actually his winery staff, only for Kaeya to appear from the crowd. He had been watching the three to see how Diluc would react to the situation. Diluc dares Kaeya to rat him out, but the Calvary Captain tells him that it isn't his style, so the secret is kept safe. As Kaeya leaves, Diluc thanks the Traveler for their assistance, giving them some compensation and that they can come to him for help should the need ever arise.
