Awakening inside a game level, Lyle York finds the system announcing he has entered Anomaly World and must escape Bloody Apartment within 24 hours. He realizes newbies are guaranteed to die, remembers a plea to not take his brother and notes their parents are gone so Sierra depends on him. The system then unlocks the Bloodthirst System and offers Berserk Mode: Bloodthirsty Butcher. Faced with a choice between dying or a risky upgrade, Lyle accepts—saying, "I'll take it of course." The episode ends with his acceptance, leaving survival and Sierra's fate unresolved.
A man finds himself in the Bloodthirsty Butcher form and, despite feeling powerful, still feels weak. Bystanders spot him and panic; one pursuer threatens to 'turn you into a pulp,' escalating into chaos as people fear for their lives. The man nervously claims he only 'just passed by' to calm them. The system detects a D‑class anomaly and awards him 2 Brutal Points, explaining 100 points unlock a second Berserk stage with a special skill. He ends the episode realizing his frightening appearance can be used to gain Brutal Points and upgrade Berserk Mode.
A player corners a terrified person in a cramped apartment, gaining Brutal Points while a D-class anomaly is detected. His stamina collapses and Berserk Mode shuts off after the five-minute limit. He checks Anomaly World rules—raise stats via missions, special tools, or anomaly crystals—and finds a crystal that multiplies his stats and extends his form to 50 minutes. The HUD then issues a new objective: Escape Bloody Apartment within 24 hours. With boosted power but a ticking clock, he decides to hunt more anomaly crystals as the countdown begins.
An anomaly ambush scatters a small group: Lyle York, his ex Yvette Hale, and classmates Kristie and Marcus. As the creature closes in, Kristie and Marcus panic and scold Yvette for running back to help Lyle, accusing her of lingering feelings. Marcus pushes Lyle to distract the anomaly, but Yvette insists she won't leave him. Lyle says he can’t keep running and, in a sudden turn, shouts, "Activate, Berserk Mode!" The anomaly reappears and the group freezes—confrontation is imminent and the outcome remains uncertain.
A D-class anomaly is detected in huge shock and the system awards Brutal Points. During a raid, teammates shout orders while one player panics, "Don't come near me!" Lyle is accused of being an anomaly; he calls it an ability. He commands a dog, "Good boy. Bring me to them," and nearby anomalies comply. Players hand the anomalies over, earning 45 Brutal Points; one player gathers them and searches for hidden equipment, puzzled this seems to break the rules. A system warning then announces Bloody Apartment is crashing and all surviving players will be kicked out in five seconds.
An alarm announces an unknown error as the Bloody Apartment level begins to crash, forcing surviving players into an emergency exit countdown. They scramble but all are expelled from the level and then receive post-run results: the group earns S-rank rewards - 10 m3 of portable space and a one-time Legendary Dimensional Blade that 'cuts through space and connects two worlds' - while another player receives a B-rank invisibility cloak. Players celebrate the escape and loot. The mood shifts when Marcus spots something in Lyle's hand and asks, 'Wait, what's that in Lyle's hand?'
In a dungeon clearing a group finds a pile of anomaly crystals that raise stats and may grant skills. Other players demand Lyle hand them over to Marcus for distribution, accusing Marcus of using them as bait. Pressured, Lyle gives the crystals to Marcus to protect his friend. Marcus then uses all the crystals for himself and refuses to share. When a rival confronts him, Marcus strikes back, calling it punishment for scaring his little sister. The victim vows revenge, leaving the group's trust broken and immediate danger unresolved.
After a prank item opens a portal and sends Sierra, Lyle's sister, and others into the disaster-class Grimwood level, bystanders panic that no player survives there. Angry players cite Marcus's retaliation while Lyle vows to save Sierra. He uses the Dimensional Blade to cut into Anomaly World, but others warn the blade only drops him into a random level. Lyle materializes in the Horror Bus level; an interface assigns the mission to ride bus 444. He checks the map and finds Grimwood absent from the route and possibly outside the city, leaving his rescue in doubt.
On a busy street 'you' are approached by a peculiar woman who keeps asking if she looks beautiful and also demands directions to Grimwood. The encounter suddenly escalates when a C-class anomaly—the Slit-Mouthed Woman—goes into shock; the interaction grants you 15 Brutal Points (bringing you to 60). The shocked anomaly begs, "Please save me! Don't kill me!" then admits she knows Grimwood's location but it's across the city. Before that can be resolved the bus arrives and someone shouts "Get on it!", forcing an abrupt departure while Grimwood's location and the situation remain unresolved.
On a city bus, a veteran Bus 444 driver refuses orders to follow another person’s directions and snarls, "Listen kid, do you wanna die?" The passenger snaps back, "Sit down, or I will kill you!" That standoff is cut short by an anomaly outbreak. A combatant activates Berserk Mode, noting its effectiveness varies by anomaly class, and smashes through C- and D-class targets, gaining Brutal Points (15, 9, 17) to reach 139. The system hits 99% and announces unlocking tier-two Berserk skill, Doom Nightmare, leaving the fighter poised at the brink of a dangerous new power.
