Chapter 2: The Data Den and the Boogeyman
The criminal underworld of Musutafu City did not smell like blood or gunpowder. It smelled like cheap stale tobacco, overheating server towers, and spilled instant coffee.
Rei Arata—the unremarkable, hollow-eyed civilian identity of the Winged Sovereign—sat bathed in the harsh, blue glare of a half-dozen computer monitors. His fingers flew across a mechanical keyboard, the rapid clack-clack-clack the only sound in the claustrophobic, windowless basement office. To the rest of the world, Rei was a twenty-something dropout with a minor, useless Quirk that let him briefly memorize strings of numbers.
To the broker known as Giran, Rei was a cheap, highly efficient data scraper.
"Let's see what you're up to today, Akio," Rei muttered, his voice devoid of the ethereal distortion he used as Nocturne.
He pulled up a decrypted police scanner frequency on his left monitor, cross-referencing it with a dark web forum dedicated to illegal vigilante sightings. It had been four months since the alleyway. Four months since he had planted the first cosmic butterfly into the chest of a desperate, bleeding boy.
Akio hadn't wasted a single day.
The screen populated with fuzzy cell phone videos and furious police reports. In the lower-income districts where Pro Heroes rarely patrolled, a new rumor was spreading. They called him the "Golden Shield"—a vigilante who threw himself into the line of fire, taking bullets and quirk blasts that healed instantly, only to retaliate with shockwaves of solid, golden-violet kinetic energy.
Rei leaned back, sipping his lukewarm coffee. A phantom warmth pulsed deep within his own chest, a sympathetic resonance tied to Akio's use of the Aegis Pulse. The power was growing. Maturing. And, inevitably, it was drawing attention.
The police scanner on his desk crackled to life, breaking the basement's silence.
"Dispatch, this is Officer Sansa. We're at the scene of the botched jewelry heist on 4th Avenue. The suspects are incapacitated. Over."
"Copy that, Sansa. Did a Pro intercept?" There was a heavy sigh on the other end of the radio. "Negative, Dispatch. It was the Golden Shield again. Suspects are bound with zip-ties, suffering from blunt force trauma and... well, concussive energy burns. Detective Tsukauchi is already on the scene. He's asking for a direct line to Eraserhead."
Rei's hands froze over the keyboard. Eraserhead. The underground hero whose entire career revolved around nullifying Quirks.
He quickly typed a command, hijacking a nearby traffic camera feed to get a visual of the jewelry store. On the screen, the tall, tan coat of Detective Naomasa Tsukauchi was visible through the digital static. The detective was kneeling next to a crater in the asphalt—a perfect hemisphere of displaced earth left behind by Akio's shield.
"I'm telling you, Aizawa," Tsukauchi's voice bled through a different intercepted channel, likely a secure hero-net frequency Rei had cracked weeks ago. "The registry is completely wrong. We have Akio identified. His Quirk is 'Eternal Vitality.' It's a cellular regeneration ability. It physically cannot produce kinetic energy or hard-light barriers."
A gruff, incredibly tired voice replied. "Quirks don't just spontaneously manifest secondary, unrelated properties at his age, Naomasa. Not unless someone pumped him full of Trigger. Did he show signs of drug enhancement?"
"None. Eyewitnesses say his mind was perfectly clear. He was protecting civilians. Aizawa... it's like he has two completely different Quirks."
There was a long, chilling pause on the radio.
"Keep this quiet," Eraserhead finally ordered, his tone suddenly devoid of its usual apathy. "If a vigilante is running around with multiple Quirks, the Commission will panic. I'll start patrolling his usual sectors. If he's getting power from an outside source, I'm going to find the leak and shut it down."
Rei smirked in the blue light of the monitors, though a cold bead of sweat trickled down his neck. So, the heroes are finally waking up. Eraserhead was dangerous. If he erased Akio's powers mid-fight, the boy could be killed, and the Butterfly would prematurely return to Rei. He would have to keep a closer eye on his champion's patrol routes.
"Fascinating, isn't it?" a raspy voice drawled from the shadows behind him.
Rei didn't flinch. He had heard the squeak of the basement door three minutes ago. He spun his chair around to face Giran, the infamous underworld broker. The man was leaning against a server rack, a lit cigarette dangling from his crooked smirk, his purple scarf looking garish against the dingy walls.
"The vigilante?" Rei asked smoothly, tapping the screen. "Just another kid with a hero complex. Nothing we can profit off of."
"Don't play dumb with me, kid, you're smarter than that," Giran chuckled, exhaling a thick cloud of grey smoke. He ambled over to Rei's desk, his eyes locked on the crater in the traffic cam footage. "The streets are talking, Rei. They say this kid went from a glorified punching bag to a heavy-hitter overnight. The heroes think it's Trigger. I know better."
Rei raised an eyebrow, keeping his heart rate steady. "Oh? And what do you think it is?"
Giran leaned in, resting his hands on the back of Rei's chair. The jovial broker facade slipped, replaced by the cold, calculating gaze of a man who survived by knowing the darkest secrets of the city.
"There are myths in our line of work, kid," Giran whispered. "Urban legends about a man who can give and take Quirks like trading cards. A Boogeyman who rules the deep underground. Now, I ain't saying this vigilante met the Boogeyman... but spontaneous Quirk evolution? That's exactly the kind of anomaly that attracts the absolute worst kind of attention."
Rei stared at the screen, letting the silence stretch. "You mean the Yakuza? Overhaul?"
"Overhaul would dissect the kid just to see how he ticks," Giran agreed, taking another drag. "But I'm talking about the big boss. The people who pay my salary. If the League, or the man backing them, finds out there's someone out there handing out custom-made power-ups..." Giran tapped the monitor right over Tsukauchi's digitized face. "...they won't just send the police. They'll send monsters. Keep your ear to the ground, Rei. If you find out who is juicing this kid up, that information is worth millions."
"I'll keep a lookout," Rei lied smoothly.
Giran patted his shoulder and sauntered toward the exit. "Good boy. Keep scraping."
As the heavy metal door clicked shut, Rei let out a slow, controlled breath. He closed his eyes and pushed a fraction of his power to the surface. Emotion Sight.
Even through the solid steel door, he could see the lingering trail of Giran's aura. It was a swampy, murky green—pure, unadulterated greed and opportunistic calculation, laced with a faint, jagged edge of genuine fear when he had mentioned the 'Boogeyman.'
All For One.
Rei opened his eyes, the vibrant colors fading back to the dull reality of the basement. The chessboard was set, and the stakes were infinitely higher than he had anticipated. The Pro Heroes were hunting for an illegal Quirk trafficker to uphold the law. The villain underworld was hunting for a golden goose to exploit.
He was standing right in the middle, a shadow playing both sides.
Rei glanced at the calendar widget in the corner of his monitor. Eight months down. Four months left until his anniversary. Four months until his power scaled up, and he could generate his second Butterfly.
He couldn't afford a brawler this time. If he was going to survive the encroaching gaze of Aizawa and the League of Villains, his next empowerment couldn't just be strong. It had to be strategic. He needed an escape route. He needed someone who desired safety above all else.
Rei cracked his knuckles and opened a new search window, diving into the civilian Quirk registries for Musutafu.
"Alright," Rei whispered into the glow of the screens. "Let's find you a sanctuary, Rin."
