He possesses a black dragon tattoo on his left arm.
Du was on his way to Eclage with his friends when they were stopped by a Laphine security guard at the city's gates. The guard required that Du and his friends fill out registration forms before they could be admitted into Eclage. Du offers to fill out the forms for them and misspells Mark's name as Madrid (apparently on purpose). He then proceeds to cut in front of an adventurer, which irritates Mark and earns him a smack on the head. Du gets upset at Mark for hitting him and tries to hurry the Laphine immigration officer, which earns him another smack from Mark. Once the paperwork was finally approved, Du dashes into Eclage while Mark apologizes to the adventurer he cut in front of.
Du's haphazard rush ends up breaking the main bridge into Eclage, causing him and his friends to fall in. After a carpenter Laphine name Fon is able to fix the bridge with the help of an adventurer, Du and Mark are relieved to be helped out of the hole they were in. Du is surprised to see the adventurer from earlier and laments about not being able to get rid of him/her. Mark apologizes for Du for breaking the bridge and Fon warns them that if they break the bridge again, they'll be off to jail. Du remarks how weak the bridge was to break under his running, to which Fon becomes furious. Mark is shocked at Du's comment and Du tries to cover up his insult. Fon gets fed up and yells at them to leave immediately and never return.
Some time later, Du runs into Glaces and overhears her asking the adventurer to seek out her friend Yube. He then boasts that he will take care of the request, but Mark reminds him to not get involved. The Rune Knight insists that it is a warrior's job to go where help is needed. He then asserts that the adventurer is now his rival and declares helping Glaces to be a competition between the two.
Du manages to find Yube and grabs him to take him over to Glaces, who becomes upset at how he's handling her friend. He then notices Oliver Hilpert wearing a wolf hoodie and tries to match him up with Maggi Steen. Maggi doesn't seem interested, which disappoints Du. He then declares that he will find Moreng and rushes off with Yube in hand and Mark, Maggi, and Alph Ackart in tow.
After finding Moreng, Du hears the Laphine talk about Yais and wonders if they're edible since Moreng remarks that Yais signify an egg. Moreng says nothing and turns his attention back to the adventurer to ask him/her about a legendary giant bird that lives in Midgard. When Moreng wishes to know more about the legendary bird from the old man he met, Du tells him to stop being meek and just ask. He then offers to find out more from the old man for Moreng and races off towards Eclage's plaza.
Du and the others get to the plaza and find the old man who begins prattling on about a Laphine name Light Standard. After hearing about a traveler with a giant feather, Du rushes off towards the gates of Eclage where the traveler was last seen.
The group finds the traveler outside the gates of Eclage who indeed had a giant feather. However, the traveler's story of battling a giant bird to get the feather was suspect. He claimed to have encountered the giant bird upon arriving in Alfheim, but Oliver points out that the old man claimed the bird was sighted in Midgard. The traveler becomes nervous and corrects himself that it was Midgard where he saw the bird and not Alfheim. Then Mark notes that the scars that the traveler claims was from the fight were too old to have been made in a recent fight and they were too scabbed to have been healed through magic. Maggi and Alph further poke holes in the traveler's story until Du accuses the traveler of having bought the feather. The traveler finally admits that he bought the feather from a cat who managed to get into Eclage. He pleads the group to stop the cat before it takes anyone else's money.
They all head back to the plaza where they encounter the Cat Hand Group merchant who was peddling multiple feathers. Alph points out that the feathers can't be real because of the way the end is shaped. The Cat Hand merchant asserts that the feather did come from Midgard, but it was too big for him to carry so he just cut it into smaller pieces and adjusted them to look like whole feathers. Maggi is astonished and wonders how big the original feather was. When the Cat Hand merchant tells them how big it was, Du is impressed and claims they could make an omelet the size of the whole plaza. Mark suggests that they should go back to tell Moreng now that they have the whole story.
After telling Moreng the truth, the Laphine becomes excited and wishes to leave for Midgard right away. The group then notifies Glaces, who is surprised by Moreng's interest in such a tale and decides to change party preparations from a birthday party to a farewell party. She then asks the group to tell Yube and the group ends up at Yube's Yai. Oliver becomes hungry for acorns and Du offers to get some for him while everyone else rest up in the Yai. After getting Oliver a pile of acorns, Du encourages him to eat more so he would grow up big and strong. However, Oliver becomes sleepy after becoming full with acorns and fades away, causing Du to recoil in shock.
Du and the others later make their way to Verus City via an elevator built by Rekenber Corporation. Du's antics proceed to break the elevator as it made its way down to the ruins, putting himself and the others in danger of serious injury. Mark and Tamarin chastise Du for breaking yet another essential structure, to which Du responds abrasively. Luckily, an adventure comes along to help fix the elevator and the elevator is secured enough to allow Du and the others to exit off safely.
Once they've arrived safely in Verus, Du remarks how the city didn't look anything like he'd imagine it to be. Mark wonders what he was expecting, to which Du responds that he thought it'd be filled with amazing treasures. Alph points out that architecture of the city was different from what he's used to in Midgard, but Du quickly changes his attention to that of the fountain nearby. As the group investigates the fountain, Alph and Tamarin are quick to notice that the fountain didn't look like it was buried for centuries; in fact, it looked as if it had been recently drained from how it looked so unusually clean for being part of a city in ruins. Alph starts to wonder if the city is as old as initially thought. Tamarin then suggests they look at the sundries nearby and Alph notes that those, too, looked as clean as the fountain. They then go to investigate a tree and Du points out that there's no sunlight in the ruins, and yet there are trees growing. Tamarin becomes shocked that Du said something so intelligent, to which Du responds angrily.
After some more exploring, the group comes across a signboard that points to the center square of the city. In his excitement, Du dashes deeper into the city, to the frustration of the rest of the group. He ends up at another fountain that looks as disturbingly clean as the other fountain. Maggi notes that she senses some strange energy in the area. Alph and Tamarin ponder on the significance of their findings while Mark smacks Du upside the head for leaving them behind.
The group then moves farther north and sees that there are much more machines in the center square than the previous district they were in. Tamarin goes to investigate a blocked off path despite Mark's warnings. Past the blocked off path is an area of the city that's been completely destroyed. Du's instinct tells him it's a bad idea to enter the blocked off area, so the group decides to follow his feeling and explore the other parts of Verus for now.
- The name Du has origins in Chinese and Vietnamese languages. In Vietnamese, the meaning of the name Du is "play." In Chinese, Du is a surname.
