Soleum wakes up on a desolate subway train representing the D-class anomaly Abyss Transpo. When the doors open at Sorrow Station, several panicked recruits step onto the platform, only to be instantly melted into twitching remains by silver droplets falling from the ceiling. Soleum uses his phone popsocket to analyze the previous fifty-six escape records. He realizes the train demands an emotion the passengers do not possess in this terrifying situation, identifying Serenity Station as the only safe exit. The tension escalates when a lost item announcement demands the left eye of a type-A male, prompting the ruthless rookie Baek Saheon to gouge out another passenger's eye with his phone corner and escape. Instead of panicking, Soleum searches the luggage compartment, finds a spare eyeball in a labeled lens case, and uses it to safely guide the remaining seven passengers of his car to the exit. They return to the corporate lecture hall to receive their employee masks, but the relief is short-lived as the company immediately melts the survivors who achieved escape through pure luck, leaving Soleum with the chilling realization that he must continue playing this deadly game to secure a Wish Ticket. To make matters worse, his survival has drawn the attention of his new superiors in D-Squad, who waste no time throwing him into his first official field assignment the very next day.

Assigned to D-Squad, Soleum is immediately pushed into a solo exploration of the F-class anomaly Make a Choice, which traps him in a dark convenience store where a blue, bloated ghost plays tag with him. If caught, the loop resets, trapping him indefinitely. During his first attempt, the ghost corners him under the register, resetting the loop and leaving Soleum shivering in the dark. Realizing he cannot survive a three-day game of hide-and-seek without losing his mind, he searches for a shortcut. He finds a hamburger box on the refrigerated shelf with an expiration date of April 7th, exactly three days from the starting date of April 4th. Soleum rushes to the cash register, manually adjusts the system clock to April 7th, and scans the hamburger's barcode to register the expired item. The system triggers an automatic expiration alert, forcing the ghost to vanish as the lights turn on. He clears the three-day trial in just one hour and twenty-four minutes, pocketing twenty million won left in the cash drawer. His record-breaking speedrun stuns his superiors, who now view him as an elite genius with iron nerves, a misunderstanding that backfires when they immediately assign him to a high-risk television studio anomaly. This false reputation forces him onto the front lines of a combined mission with the company's elite squads, where his survival instincts will be tested to their absolute limits.

Soleum enters what is supposed to be a simple quiz show anomaly, only to find himself trapped in the A-class disaster Chorus of the Sacrificial Lambs. In this deadly studio, incorrect answers or broadcast disruptions result in the host incinerating the contestants or cutting off their heads to place them on hovering silver trays, where they are forced to sing an endless, agonizing melody. Desperate to stall for time, Soleum uses a Smiley Sticker from his secret Alien Shop purchases, soaking it in an Alice Picnic Set double-effect potion, and slaps it onto the TV-headed host to force a commercial break. He uses a communication button to contact his squad leader, Lee Jaheon, who uses emergency supply equipment to shoot a battery through the portal, denting one of the silver trays. When the broadcast resumes, the pig-headed conductor tries to attack, but the TV-headed host, furious that the damaged tray is ruining the quality of his show, incinerates the conductor instead. The studio collapses, and Soleum escapes with his team, earning forty thousand points. However, this miracle clear makes him a prime target for recruitment by the elite A-Squad, forcing him to use his office politics skills to decline the promotion so he can stay under the radar. His attempts to remain unnoticed are completely shattered when he is dragged into a massive theme park board game alongside the very rookies he tried to avoid.

Soleum, elite assistant manager Jin Nasol, and Y-squad rookie Jang Heo-un are pulled into Cheerful Theme Park, a B-class board game anomaly. They board the Fantasy Train, and Soleum uses his remote-hand coin to pull the emergency speed lever to maximum, successfully skipping the terrifying visual events. However, the red rabbit mascot Magic Bunny corners them at the end of the line, demanding they sacrifice a teammate to proceed. Jin Nasol prepares to throw the useless researcher to the monsters, but Soleum uses his knowledge of the rules to convince her that killing a teammate will trigger a team-wide penalty. He guides them to the western edge of the red zone and breaks through a brick wall to enter the hidden blue water park zone, escaping the red rabbit's pursuit. The blue dragon mascot rewards him with a permanent Membership, which leaves a glowing Socius tattoo on his wrist. Soleum later uses a Good Friend plushie to summon the TV-headed host Braun as a personal companion, giving him a powerful ally for his next forced descent into the Manor of the Blind. This new partnership will prove vital as the company prepares to send him into an informational contamination trap where his very eyes are the price of admission.
