Newcomer/Synopsis

History
At some point, Newcomer joined the ranks of the immoral people; his pseudonym was presumably given as a result of being the newest member. His talent at creating dungeons and managing the system quickly became apparent, and he became the primary handler of matters related to Earth. He seemed to have done his research on Earth, knowing the cultural customs (though somewhat vaguely).

He interacted with Chatterbox at some point; the meeting went poorly, with Chatterbox believing him "too talented" and stuck-up.

Synopsis
Newcomer was assigned to work directly with Han Yoojin, who the immoral people referred to by the pseudonym "Honey". He took over handling the system responses to Yoojin's skill usage, personally writing the Promising Sprout skill windows along with some of the others.

He first made contact with Yoojin seemingly by accident, notifying him that he'd found him. This inadvertently created a glitch that caused the Gold Beak Maiya to appear, and Newcomer hastily apologized before cutting off contact.

During Yoojin's first proper meeting with the immoral people, Newcomer participated in the chat and ensured that any excessive information was censored, so as not to trigger a shutdown of the channel between the two parties. For the most part, he remained quiet and let the others talk, piping in to request that Yoojin use Promising Sprout less often and that he call him "oppa" (still believing, at this point, that Yoojin was female).

Newcomer monitored Yoojin's subsequent interaction with Yoohyun while managing other system-related interactions. Once the Han brothers left the dungeon, he went to speak to Water Droplet about his reservations regarding Yoojin and Yoohyun, as well as his preference for Yoo Myeongwoo. She dismissed most of his concerns; however, he was successfully distracted and cheered up by the appearance of an unnamed, ghost-like member of the immoral people, and resolved to decorate a room in the immoral people's base for Yoojin.

When Yoojin takes a number of S-ranks to the Black Golem's City dungeon, intending to raise Kim Sunghan's rank, Newcomer notices the space interference caused by Chirpie's attempt to summon him back home and warns Yoojin. The distortion caused by the teleportation attempt results in the Babar's appearance. Newcomer anxiously discusses the matter with Tree, suspecting the filial duty addicts of having tried something, and watches as Tree assigns rewards for the Babar's defeat.

When Yoojin next comes to a dungeon to meet with the immoral people, Newcomer temporarily replaces the dungeon he enters with the snowy dungeon Newcomer himself constructed. The Toy Soldiers populating the snowy dungeon attack Yoojin and Yoohyun, who have entered together, and Newcomer calls them off as soon as he appears. He takes the form of a volleyball with a face drawn on, in an homage to Cast Away's Wilson, which bewilders Yoojin. Once Newcomer has set up a sound-blocking force field, he hints at Yoohyun's connection to the filial duty addicts and explains the snowy dungeon's nature. He then proceeds to answer Yoojin's questions to the best of his ability. When Yoojin asks if there's no one who can help the immoral people save for him, Newcomer suggests finding someone with skills like his. He also agrees to make the stamina potion dungeon appear sooner, and offers to eliminate the glitch-like monster Chirpie, much to Yoojin's horror. With a final explanation of the regression's effect on consumable items and overwritten existences, he bids farewell, and disappears along with the snowy dungeon.

Newcomer (in his volleyball form) later interrupts Yoojin's confrontation with Diarma, infuriated by the filial addict cheating and showing up in his real body to kill Yoojin. To even the scales, Newcomer connects Water Droplet to Yoojin, so that the duo can fight Diarma off. Once Diarma has been killed and Yoojin is safe, Newcomer returns to listen as Water Droplet and Yoojin talk. He's startled to learn that the Bird Who Counts Stars has taken the pre-regression Yoohyun's body, but continues to listen silently as Water Droplet explains the source and the two sides of the transcendents. When Water Droplet explains how one can withstand the source's siege until it grows tired, as a method of warding off its attacks, Newcomer cuts in to point out that one can directly attack the source until it gives up as well, which Water Droplet immediately rebukes him for mentioning due to its near-impossibility.

Yoojin summons Newcomer's dungeon in order to block the water dungeon sent by Jellyfish, Diarma's successor. Newcomer comes out to meet him, only to find that he's brought Sung Hyunjae and Bak Yerim with him; he's excited to see "Chain", who he knows has broken his contract with the late Diarma. Yoojin interrupts and asks to speak with Water Droplet; Newcomer obligingly connects them and waits. Once Yoojin's finished making a deal with her, Newcomer lets him know that the price Water Droplet will pay will make it difficult to speak with her for a while. Yoojin questions him about his knowledge of Sung Hyunjae, and Newcomer explains that Crescent Moon was the immoral person in contact with him, helping him break his contract with Diarma. Yoojin attempts to shake down Newcomer for a deal as well, but since he needs to manage the system, he offers to give personalized items to Yoojin's dungeon raiding parties.

Yoojin breaks out of Seseong Guild to come visit Newcomer, who's alarmed at him seemingly having come alone. Yoojin shows him Eunhye, and Newcomer is excited about meeting Shalos. He tells Yoojin what he knows about Shalos' history, including his friendship with the Bird Who Counts Stars, and has to hastily assure Yoojin they're still looking for the white bird. Newcomer grows panicked when Yoojin tells him about Jellyfish's visit, insisting that Yoojin must not sign a contract with her. As a not-quite-bribe, he tells Yoojin to come back in about three weeks for a personalized dungeon with item and skill rewards he'll find useful. He leaves after passing the conversation to Tree so that Yoojin can ask about Crescent Moon, visibly distressed enough that Tree remarks upon it.

Newcomer comes back to meet Yoojin shortly after, when he shows up with Choi Sukwon in tow. He commands the Toy Soldiers to kill the transformed Choi Sukwon, then rushes to meet Yoojin, asking what happened. Upon learning about Choi Sukwon's transformation, he explains that it's a rare case, and helps Yoojin retrieve the stolen memories. During this process, he also advises Yoojin about how he can use Choi Sukwon's magic stone, since he's a Caregiver and not limited to curse- and poison-attribute dragons. With a final comment about the mechanics of magic stones' appearances, he leaves.

Yoojin returns with Yoo Myeongwoo, Peace, and Blue, hoping to learn more about the personalized dungeon and ask some questions of Newcomer. The transcendent in question appears promptly, greeting Myeongwoo and explaining that he constructed the dungeon they're standing in. Newcomer nervously asks Yoojin what he's here about, and when Yoojin asks about Sung Hyunjae's influence on the magic stone in his chest, Newcomer assures him that Sung Hyunjae can't affect it so long as he's human. Alarmed by the ominous statement, Yoojin demands to know more, and Newcomer tries to reassure him, only to trip up and reveal that he's aware of some of Sung Hyunjae's skills. He tries to defend himself by claiming that the system admins only pay attention to some people and skills, and must maintain the privacy of those they do know about. All the same, he assures Yoojin that Sung Hyunjae is human, and that Crescent Moon and Water Droplet are both still asleep, unable to answer questions. He changes the subject, reminding Yoojin about the personalized dungeon; they negotiate the items and skills Yoojin can request, as well as the number of people he can bring, and Newcomer's deadline. He shuts down Yoojin's queries about modifying other dungeons similarly, then prepares to leave. However, before he can vanish altogether, Myeongwoo reveals that he can understand and manipulate the artificially-created dungeon. Newcomer is furious at him modifying his work without permission, but lets him off the hook as his junior in the field, then leaves properly.
