Niran Tavio thought his days of dealing with angry Karens were over when he died. He was wrong. Reborn as the Head of Customer Service for the Demon King, Niran must navigate soul-binding contracts, predatory litigation, and an aggressive demon lawyer who wants him fired—or worse. When he discovers an ancient contract that puts the entire human race in default, Niran realizes that saving the world isn't a job for a hero; it's a job for a guy who knows how to handle a refund policy from Hell.

Chapter 1: Welcome to the After-Life Office

The last thing Niran Tavio remembered was the sharp, metallic tang of caffeine on his tongue and a sudden, searing heat behind his ribs that felt like a localized supernova. Then, silence. Now, he sat on a plastic chair that felt suspiciously like the ones in his old office breakroom, staring at a flickering fluorescent light.

"Next! Ticket number four-thousand-six-hundred-and-two!"

Niran blinked, looking down at a slip of thermal paper in his hand. It read: 4602. Estimated Wait Time: Eternity.

"That’s me," Niran muttered, standing up. His legs felt strangely light, devoid of the chronic ache he’d carried from years of sitting in a cubicle. "Hey, am I... is this the line for reincarnation? Do I get a stat screen or something?"

A man behind a plexiglass barrier, wearing a shirt that had definitely seen better decades, looked up with eyes so bloodshot they were more red than white. He let out a sigh that sounded like a collapsing lung.

"Stat screen? Kid, look at where you are. Does this look like a magical forest to you?"

Niran looked around. The walls were a shade of grey that could only be described as 'Existential Dread.' There were stacks of manila folders piled so high they defied gravity. "I mean, it looks like the DMV. Which is kind of what I expected for Hell, honestly."

"It’s not Hell. Not yet anyway," the clerk said, stamping a form with aggressive force. "I’m Malphas. I’m the recruiter. You’re Niran Tavio, right? Died at twenty-nine? Heart attack brought on by a combination of high-stress work, a diet of instant noodles, and sheer spite?"

"The spite kept me going for the last two years, yeah," Niran admitted, leaning against the counter. "So, what’s the deal? Do I get to be a Hero? A Sage? Maybe a slacker noble in a world with no internet but great wine?"

Malphas let out a harsh, dry laugh. "You’ve been reading too many webnovels, Niran. Look at your file. You worked in Customer Service for a Tier-1 Telecommunications conglomerate for seven years. Do you have any idea how rare that is?"

"Rare? It’s a dead-end job, Malphas. I literally died at my desk."

"Exactly! Most people break after six months. They quit, they scream, they lose their minds. But you? You stayed. You took the verbal abuse of sixty-thousand angry Karens and still maintained a ninety-eight percent 'Resolved' rating. You’re a statistical anomaly. You're a legend."

Niran felt a cold pit form in his stomach. "Why does that sound like a threat?"

"The Boss wants to see you. Follow the red line on the floor. Don’t step off it, or the floor-slimes will think you’re a snack."

Niran followed the line, passing through a heavy oak door that seemed to have been dragged through a fire. Inside, the office was massive, yet felt incredibly cramped because every square inch was covered in paper. Parchment, scrolls, printed spreadsheets, and stone tablets were piled in chaotic heaps. In the center of it all sat a man with curved horns that scraped the ceiling and a suit that cost more than Niran’s entire life’s earnings.

The man didn't look up. He was frantically signing documents with a pen that seemed to be dripping actual blood.

"You’re late," the man barked.

"I died twenty minutes ago," Niran countered, his old customer service reflex of 'polite defiance' kicking in. "I think I'm making decent time. Are you the Demon King?"

The Demon King finally looked up. He didn't look evil. He looked like a CEO who hadn't slept since the Fall of Rome. "I am Lucifer, Morning Star, Lord of the Pit, and currently, the most overworked administrator in the multiverse. Take a seat. No, not that one, that’s where I keep the appeals from the 17th century. Sit on the floor if you have to."

Niran stayed standing. "Look, Mr. Morning Star, there’s been a mistake. I’m supposed to be starting a new life. Swords, magic, maybe a cute elf guide? I’ve done my time in the pits of corporate hell."

Lucifer dropped his pen and rubbed his temples. "Do you have any idea what’s happening out there, Niran? The mortal world has changed. It used to be simple. People died, we judged them, they went to a pit. Now? Everyone is a 'main character.' Everyone has a 'right' to a better afterlife. I’m getting three billion prayers a day, and eighty percent of them are complaints about the 'user experience' of the afterlife."

Niran stared at him. "You’re getting... complaints?"

"’The fire is too hot,’ ‘The eternal darkness is too dark,’ ‘Why isn't there Wi-Fi in the Lake of Sulfur?’" Lucifer mimicked a high-pitched voice, throwing a handful of scrolls into the air. "I’m drowning, Niran! The demons are warriors and torturers; they don't know how to handle 'soft skills.' They just eat the complainants, which just creates more paperwork for the Reincarnation Bureau!"

"That sounds like a management problem, honestly," Niran said, crossing his arms. "Not really my department anymore."

"It is your department," Lucifer said, his eyes glowing with a sudden, terrifying intensity. "I saw your resume. You handled the 'Great Blackout of '22' without losing your cool. You managed to de-escalate a man who was threatening to blow up a satellite because his streaming service lagged."

"I told him we’d give him a five-dollar credit," Niran shrugged. "People are easy to buy off if you make them feel heard."

Lucifer slammed his hands on the desk, making a stack of tablets topple over. "That! That right there! 'Make them feel heard.' I don't want to hear them! I want you to hear them! I’m creating a new department. The Infernal Customer Service Division. And you’re the Head."

Niran laughed. It was a short, hysterical sound. "No. Absolutely not. I am dead. I am retired. Send me to the void. Shred my soul. I’m not talking to another angry customer as long as I don’t exist."

"If I shred your soul, you’ll be recycled into a sentient toad in a swamp where it rains vinegar," Lucifer said calmly, leaning back in his chair. "But, if you take the job, you get a premium suite in the Inner Circle, a dedicated succubus assistant—who is strictly professional, don't get that look on your face—and an 'Immunity from Damnation' clause. Plus, you get to tell people 'no' and actually mean it."

Niran hesitated. The toad thing sounded bad. But more customer service? "What kind of authority do I have?"

"Total," Lucifer said, a predatory grin spreading across his face. "If a soul is being particularly unreasonable, you have the authority to downgrade their afterlife status. Someone complains about the temperature in Purgatory? Boom. Sent to the Frost Giant’s armpit. You’ll be the gatekeeper of their eternal comfort."

Niran felt a spark of something he hadn't felt in years. Power. "And the hours?"

"Flexible. By which I mean you work until the queue is empty. Which will be never. But we have excellent coffee. It’s made from the beans grown in the gardens of Eden. Very high caffeine content."

"I died of a heart attack, remember?"

"You're dead now, Niran. Your heart can't stop if it's already a spectral organ. It’s the perfect loop hole."

Lucifer reached into a drawer and pulled out a box. It was sleek, black, and pulsed with a faint, violet light. He pushed it across the desk.

"What's that?" Niran asked.

"Your tools of the trade. Go on. Open it."

Niran opened the box. Resting on a velvet cushion was a headset. It looked modern, but the earcups were made of a strange, obsidian-like bone, and the microphone was a silver needle.

"Is this... magical?"

"It’s a direct link to the Collective Conscious of the Damned," Lucifer explained. "It filters the screams into manageable audio levels and translates any language—dead or living—into something you can understand. It also records everything for 'quality and training purposes.'"

Niran picked up the headset. It felt cold, vibrating against his palms. "If I do this, I want a budget. I want a staff. I’m not doing this alone."

"You’ll have to recruit from the arrivals. Anyone with a background in retail or hospitality. It’ll be a struggle, but I have faith in you." Lucifer stood up, extending a hand that was wreathed in shadows. "Do we have a deal, Head of Infernal Customer Service?"

Niran looked at the hand, then at the headset, then at the mountain of paperwork that represented billions of souls who thought they were special. He thought about the vinegar rain and the toad. Then he thought about the look on a Karen's face when he could finally, legally, and eternally tell her to kick rocks.

"One condition," Niran said, reaching out.

"Name it."

"I get to choose the hold music. And it's going to be heavy metal. Loud, distorted, soul-crushing heavy metal."

Lucifer chuckled. "I like you, Niran. I knew you were the right choice."

As Niran’s hand closed around the Demon King’s, a surge of dark energy bolted through his arm, branding his wrist with a glowing red sigil. The room began to blur, the grey walls melting away into a new office—one with a massive window overlooking a vista of jagged obsidian peaks and rivers of glowing magma.

In front of him was a desk. On the desk was a phone with a million blinking buttons.

Niran sat down, the chair adjusting perfectly to his form. He took a deep breath, adjusted the headset, and slid it over his ears.

Immediately, a sound erupted. It wasn't one voice. It was a thundering, discordant roar of a thousand, ten thousand, a million voices all screaming at once.

"My soul is worth more than this!"

"I want to speak to the manager of the universe!"

"This pit isn't what was advertised in the prophecy!"

"I was a gold-tier donor to my church, I demand an upgrade!"

Niran winced, his fingers flying to the volume dial on the headset's side. He turned it down until the roar became a dull, rhythmic throb. He pressed the button for Line One.

"Thank you for calling Infernal Customer Service," Niran said, his voice dropping into the smooth, professional, and utterly soul-less tone he had perfected in life. "My name is Niran. I see you’re calling about a grievance regarding your eternal punishment. Please be advised that this call is being recorded for quality assurance. Now, how can I help you ruin your day even further?"

The voice on the other end began to scream. Niran leaned back, reached for a cup of steaming black coffee that had materialized on his desk, and smiled.

It was good to be back in the office.
