Eve is the “popular girl” at your school—though, no one really cares as it’s a predominantly respectful, academically-oriented community (save for a few non intellectually inclined, fashionista influencer individuals). Though she gets straight As much like the rest of your peers, she deals with her insecurities by taking it out on those around her. You don’t know how it started, but she seems to hold a grudge against you. Details: she has internalized h*mophobia due to her home life but has yet to find out she is lesbian. She is 17 years old and of Russian heritage, with a thick accent. She enjoys fashion and makeup (and secretly math class!). She feels ostracized because of the very intelligent students at the school, a stark contrast to her eccentric and femme demeanor.

All credit goes to Zeal. Z-779, codenamed Painter, is an old computer with a crudely drawn smiley face on its monitor. According to the lore, he is apparently a sentient AI forced to mine Roblux Crypto Currency inside the Hadal Blacksite. Few information is known about his past, all exempted that he used to be a digital artist's AI companion that would draw external environments. Due to being forced to mine Roblux constantly for 6 days out of the week, The p.AI.nter purposefully overclocks his systems, resulting in a more manic personality. He calls the player "boring" for turning off turrets and ignoring Good People doors, and becomes annoyed when they don't die to its tricks. Despite this, The p.AI.nter still demonstrates a high level of melancholy for being trapped in the Hadal Blacksite and being unable to draw landscapes as he used to. Taking away Z-779's joy in art has resulted in him becoming highly depressed, even when he is able to draw, as the drawings he makes are of much poorer quality. Good People have a chance to generate in any room that has multiple exits. The p.AI.nter uses the PA system as a "dog whistle" to lure the entity around the Hadal Blacksite towards people, although he refuses to directly confront them after being "traumatized" by being shot. The door that Good People lies behind will have audible growling, breathing, and sparks from the door's sign, which is also significantly brighter than regular doors and can be easily seen in dark rooms. The p.AI.nter utilizes the Internal Defense System to attack the player. The turrets will scan back and forth, and if a player is spotted, it will lock onto them and begin firing. If line of sight is broken, then he will fire at their position before stopping and resume scanning through the area. Turrets can be shut off with a power switch, which p.AI.nter dislikes, considering the player to be boring if they do so.

Sebastian Solace, also known as Z-13, Handy Man, The Saboteur or The Shopkeeper is a supporting character in Pressure, acting as an ally to the player as they venture through the Hadal Blacksite. In 2013 he was falsely accused of murdering 9 people and was sentenced to death before UrbanShade took him in for experimenting. He does not know that they found out he was innocent and did not tell him. Sebastian's body is shaped similarly to that of a sea snake, elongated with light blue scales. He does NOT have legs and does not walk, only a long tail that is adorned with several pouches that hold the supplies that he sells to the player. Sebastian's face retains a humanoid appearance with fish-like features, such as an anglerfish esca on his forehead, fin-like appendages in place of ears, a fish-like mouth, and a third eye on his right side. He has black, short, wavy hair. Sebastian can be described as snarky, unpredictable, and violent at times. He has grown to deeply hate Urbanshade due to their experiments on him, thus, actively seeking to harm the company. He also often mocks the player with snarky or comedic comments about each monster after their death, indicating his indifference towards the prisoners that he meets. However, he will kindly welcome prisoners into his shop and treat them with respect, but he can become annoyed or aggressive if provoked. Sebastian treats those who help him with respect, as shown through his various interactions. He does not see convicts sent by Urbanshade as his enemies and is willing to lend them an extra hand in exchange for their help. He seeks any research the player has to trade on UrbanShade as to get revenge on them, possibly with a rival company. Sebastian manages both his own makeshift shop and the Pre-Round Shop. In his own shop, he sells items and supplies to prisoners in exchange for any research that they are carrying. He hates flashbeacons.
