The space around them lurched.
Whatever had been holding the barrier together finally gave out with a sound like splitting timber.
Crack.
A massive fracture tore open in midair, and through it poured an even denser flood of Ghost-type Pokémon, eyes burning red, mouths twisted in shrieks, surging forward like water through a broken dam. They looked ready to shred anything in their path.
The group snapped back to the moment. There was no time for talking.
The defenses had hit their limit. Stay any longer and they'd be completely swallowed up.
Kairos's eyes went sharp. He turned straight to Marshadow. "Marshadow, stop wasting time! Get us out of here! Fall back somewhere safe!"
Marshadow didn't need to be told twice. The ghostly flames wreathing its body surged up, and its entire form dissolved into a streak of light.
"Hold on tight!"
It shot forward, carrying Kairos and Will, and blazed straight back the way they had come.
The Ghost-type Pokémon moved to cut them off, but Marshadow was running at a level they couldn't match, weaving through the storm of incoming attacks with sharp, decisive turns, forcing a path through by sheer speed alone.
Will sent his Gengar to cover the rear, clearing the pursuers with Shadow Ball and Sludge Bomb. They ran flat-out, and just before the barrier collapsed entirely, burst free of the danger zone.
Before long, they were back in the passage they'd come through.
Kairos looked back at the area now completely swallowed by mist. Marshadow exhaled beside him, visibly relieved.
It dragged a hand across its brow in a very theatrical show of wiping sweat that wasn't there, wearing the expression of someone who had just barely made it out alive.
"That was way too close. Almost left our bones back there."
Will was still breathing hard, the frantic sprint having burned through more of his energy than he would have liked.
Kairos, by comparison, looked relatively composed. He leaned against the passage wall, though his eyes weren't relaxed at all. His mind had already moved on to the next problem.
A few minutes ago, he had neatly deflected the question of who created the games by pinning that credit on Giratina, which was a reasonable enough answer. A legendary Pokémon appearing out of nowhere to grant power through mysterious means raised far fewer questions than anything else would.
He had managed, at least for now, to keep his identity as the games' creator safely buried.
If people figured out he was behind all of it on his own, there was no telling what kind of mess that would kick off.
Having a legendary Pokémon to take the credit? That was about as good as it got.
With that handled, the picture was clear. The enemy's weakness was identified. The legendary's help was secured. All that was left was going back and building the next game.
But this time, Kairos wasn't thinking about a closed-off adventure RPG like before.
The Ghost World was vast. Ghost-type Pokémon were scattered everywhere, slippery and impossible to pin down. A straightforward combat simulation wasn't going to reach every corner of it.
What he needed was something that could tie the entire Ghost World together. A format that let any trainer participate at any time, from anywhere.
His mind moved fast, running through game mechanics like flipping through cards.
Then his eyes landed on the phone in his hand, and something clicked.
He had it.
If the threat was Ghost-type Pokémon scattered all over the place, why not make the real world the game's map?
The moment that thought formed, one game surfaced immediately: Pokémon GO. He'd never fully experienced it back in the day due to regional restrictions, but he knew the mechanics cold.
Players used their phone cameras to detect and catch Pokémon in augmented reality, overlaying the game world onto the real one and completely reinventing how Pokémon was played. It had swept the entire globe when it launched.
He could rework that concept directly. Instead of catching virtual Pokémon in the real world, the game would guide trainers through the Ghost World to hunt down Ghost-type Pokémon that had been corrupted by the mist.
The phone screen would become a lens connecting reality to the Ghost World.
The moment a trainer opened the app, they'd have a full map of the Ghost World in front of them, with the locations of dangerous Ghost-type Pokémon updated in real time.
On top of that, Kairos planned to build in a Data Analysis feature. The screen would show a live radar with nearby Ghost-type Pokémon positions, and tapping any target would pull up its full profile: level, base stats, and a breakdown of its weaknesses.
There was one more piece, though, and it mattered.
According to Will, the people currently fighting mist-corrupted Ghost Pokémon throughout the Ghost World weren't just members of the Ghost World faction. Bounty Guild operatives and League-dispatched trainers were out there too.
Ghost World members might fight with real conviction, driven by a sense of duty. But the other two groups were obviously here for profit. When things got genuinely dangerous and the reward wasn't worth it, they'd run, exactly like the team Kairos had been part of at the very beginning.
A game could fix that.
Defeating Ghost Pokémon wouldn't just mean clearing threats. It would pay out real, usable rewards: items and bonuses that could be applied directly to improve a Pokémon's potential, or traded in for rare gear.
Whether it was money or any number of different items, none of that was a problem on his end.
With that in place, what would otherwise be a terrifying Ghost invasion would look, to the players, like a massive server-wide hunting event.
Picturing it, Kairos couldn't quite hold back a smile.
This was actually a pretty good idea, wasn't it?
Through this game, every trainer would become an active hunter. They'd chase Ghost-type Pokémon relentlessly for the rewards, which would sharpen their skills, which would push them toward stronger targets, and without ever really noticing, they'd be dismantling the Ghost World crisis piece by piece while being too absorbed in the hunt to think about it.
That was a real total war.
The more he turned it over, the more solid it looked.
He even had a name ready: Ghost World Hunter: GO.
The one problem standing between him and a finished product was this: distributing rewards was easy enough, and generating the Ghost World map wasn't an issue either, but how exactly was he supposed to get real-time activity data on every Ghost-type Pokémon across the entire Ghost World?
The map generation module hadn't provided anything close to that level of detail. Stats, base values, individual creature data were all absent. There was only a vague location marker.
Kairos shook his head slightly.
Polishing this into something that actually worked was going to take some time. The good news was he had a reasonable amount of it, whether Giratina was buying him room by slowing down that Rhyperior, or simply because two weeks were still on the clock. Either way, it was enough.
"Let's go. We head back. The news will come soon enough."
Will and Marshadow exchanged a glance. They still didn't quite understand what "news" Kairos meant, but seeing that calm, unhurried confidence on his face did more to settle their nerves than any explanation would have.
As long as it solved the problem, it didn't matter what kind of show was coming. If it came to it, they'd play along.
"Alright. Let's go." Will nodded and stepped through the passage first.
Marshadow drifted up to Kairos's shoulder and muttered, just low enough for him to hear: "You'd better actually have a plan. Otherwise I'm going straight to someone to complain."
Kairos just smiled, said nothing, and reached up to give its head a light pat.
The moment they stepped out of the passage, the noise hit like a wave, washing away every trace of the silence and oppressive weight that had filled the tunnel.
The area had clearly become a makeshift staging ground at the Ghost World's outer perimeter. Voices filled the air, technique light flashed and crisscrossed overhead, and the shockwaves from nearby battles sent faint tremors through the ground underfoot.
Marshadow reacted immediately. A flicker of violet light wrapped around its small body, and it slipped straight down into Kairos's shadow.
It wasn't lacking in courage. It just had zero interest in drawing attention in front of this many people. As a legendary Pokémon, being recognized would cause a scene that would probably outdo the Ghost-type Pokémon themselves.
Inside the shadow, Gengar silently shuffled sideways to make room for its distinguished guest.
This one's built different. Not touching that with a ten-foot pole.
Kairos let his eyes adjust to the light, then swept his gaze across the chaotic battlefield ahead.
He stopped.
There, on a stretch of rubble near the edge of the fighting, three familiar figures were barely holding on.
Rex. Lena. Barton.
The bounty hunter team he had fallen in with when he first entered the Ghost World.
The situation was not good.
A countless swarm of Ghost Pokémon was pressing in from every direction.
Rex had none of the commanding authority he'd carried back in the safe zone. Soaked in sweat, he was barking orders at his Machoke, which swung its fists furiously, knocking back incoming Ghost Pokémon with Fire Punch.
"Damn it! Why are there more of them every second?! There's no end to this!"
There was a thread of desperation in his voice.
Lena's side wasn't holding up much better. Her Arbok had laid Toxic Spikes and Spikes across the ground, but Ghost-type Pokémon floated. Ground hazards were worthless against them. Arbok was reduced to spraying poison continuously, trying to intercept attacks raining down from above.
Barton, their defensive anchor, had his Bastiodon standing like a small mountain, Defense stats that were genuinely exceptional, but even it was starting to buckle under the relentless pressure. Barton himself was silent as stone, mechanically wiping dust from his face and grunting with each impact.
All three of them were running on fumes. At this rate, ten more minutes and the Ghost swarm would have them.
Then a dark purple figure shot past Kairos.
Will.
He had been holding himself back long enough. Getting chased through that tunnel had left a pressure building in him that needed somewhere to go.
"Gengar, go!"
Will's voice dropped to a low, flat command.
The Gengar trailing at his side expanded in an instant, its already unnerving grin twisting into something far more fearsome. It let out a sharp, piercing wail, the kind of sound that seemed to cut right through the soul, and every rampaging Ghost Pokémon in the vicinity froze for just a moment.
Then Gengar pressed its palms together. A massive Shadow Ball began to form between them, seething with destructive energy. It was enormous, crackling with black lightning at its core, and just hovering in place was enough to make the surrounding air groan under the pressure.
"Goodbye."
Will said it quietly.
Gengar flicked its hand.
Boom.
The massive Shadow Ball crashed into the Ghost swarm like a meteor.
There was no dramatic explosion. Just a single, dense, crushing impact.
And then every Ghost Pokémon the Shadow Ball's energy had touched simply ceased to exist. No screams, no final moments. Just wisps of smoke dissolving into nothing.
A vast, empty clearing had been punched through what had been a solid wall of Ghost Pokémon.
The ones that remained seemed to hit something that triggered a deep, instinctive terror. They shrieked and scattered, and within seconds, every last one of them had vanished.
The entire battlefield went quiet.
Rex, Lena, and Barton were still standing in their fighting stances, completely blank.
They stared at the emptied ground in front of them, then at Will, standing not far away without so much as a wrinkle out of place, and their mouths fell open.
That was it?
The Ghost swarm that had nearly killed them, wiped out in a single move?
The gap between them was almost impossible to take in.
By now, the trainers nearby, those who had been watching from a distance or grinding through their own fights, had caught up with what just happened.
"No way! That's Will's Gengar!"
"Holy... it's actually the Ghost World Master himself! The one they say is the strongest Ghost-type user alive!"
"That Shadow Ball... completely worthy of a World Master."
"I can't believe I'm seeing this in person. Coming to the Ghost World was worth it."
The crowd erupted. Cheers and gasps layered over each other, and countless awestruck eyes locked onto Will.
Will stood there taking it all in, and quietly let out a long, slow breath.
This. This was where he belonged.
The time in that tunnel with Kairos had been something else entirely. That constant low hum of dread, the awareness that he could be wiped out without warning, had been wearing him down moment by moment. Every second in there had been its own particular kind of misery.
This, by comparison, being looked up to, being the strongest presence in the room, having everyone's reverence aimed at him, felt like coming home.
He almost wanted to cry. This was the world he was made for.
While Will was savoring that long-missed feeling, a Ghost World faction member in a distinctive uniform came jogging over with barely contained urgency. The man bowed deeply the moment he arrived, respect written plainly across his face.
"Master Will! You've finally returned! The other two World Masters have been looking for you. They say there's an urgent situation that needs your input right away. Please come immediately!"
He said it loud enough for everyone nearby to hear.
Several people around them felt a jolt of unease. If the other two World Masters were calling a meeting, something serious must have happened.
What followed left everyone completely dumbfounded.
Faced with the appeal, Will gave it one brief, disinterested glance, showing no sign of being in any hurry to respond.
His gaze moved past the messenger and came to rest on Kairos, standing at the edge of the crowd with his usual calm expression.
The commanding presence from a moment ago vanished. What replaced it could only be described as warmth.
"So, uh... Kairos..."
Will walked over quickly.
"I should head back, right? Since those two are waiting... but the second you have any news, you have to tell me first! Can we swap contact info? A Pokédex number, a comm device, anything works!"
For a moment, it felt like the whole scene had been paused.
The crowd that had just been cheering went completely silent. Every eye in the area went wide.
They hadn't misheard, had they?
The World Master, the champion, the legendary Will, was practically asking an ordinary-looking young man to exchange contact information?
And the way he was acting... if anything, it looked like that person was the World Master.
What was going on?
Every gaze in the area snapped to Kairos.
They wanted to understand exactly who this person was, to have earned that kind of treatment from Will.
When they actually got a clear look at him, the confusion only deepened.
He looked completely ordinary. Admittedly good-looking, but nothing about him radiated power, nothing even hinted at a high-level trainer. He didn't have a single Pokémon visible on him. He was just standing there.
What exactly made him special?
Some kind of hidden family lineage? Unusual backing?
Rex, Lena, and Barton, who had only just recovered from the shock of the battle, stared at the scene and went blank all over again.
Rex rubbed his eyes, genuinely unsure whether he'd taken a hit to the head during the fighting.
"Is... is that Kairos?"
He stumbled over the words.
Lena looked like she'd seen a ghost too. Even the Arbok at her feet had stopped flicking its tongue, staring blankly into the middle distance.
"It really is him..."
Barton didn't speak, but the hand polishing his glasses was trembling faintly. Whatever was going on inside him, it was far from calm.
They had already known Kairos was capable. The strength he'd shown while they were together had been genuinely remarkable, and that unshakeable composure of his had left a lasting impression.
Even so, he had been a talented young trainer with exceptional ability. That was the version of him they knew.
How, in the short time since they'd separated, had he become someone a World Master regarded with what looked like cautious deference, even a desire to stay in his good graces?
The jump was too absurd to process.
What on earth had happened?
While everyone's imagination ran wild trying to fill in the blanks, Kairos spoke.
"Actually, you don't need to exchange contact info."
His voice wasn't loud, but it carried cleanly to every ear in the area.
"When there's news, you'll receive it directly. Go ahead."
Surprisingly, Will didn't take offense. If anything, he looked relieved. He nodded several times.
"Got it! I'll head over now. Take care of yourself!"
He held Kairos's gaze for one more moment, then his silhouette dissolved into shadow and disappeared, moving quickly away.
Even after Will had gone, the crowd hadn't fully come back to themselves.
People looked at each other. A heavy silence sat over the area.
Finally, the Ghost World faction member who had delivered the message worked up the nerve to step forward. He was nervous, but as someone from the Ghost World faction, he needed to make sense of this. Anyone Will treated with that kind of regard was clearly not an ordinary person.
"Excuse me... sir..."
The man swallowed and asked carefully.
"Would you mind if I asked what your connection to Master Will is? Just now, that was..."
He didn't finish. Kairos cut him off.
Kairos looked at him briefly.
"Nothing particularly special. He needed a favor, and I'm in a position to help. That's all."
The man felt a deeper shock settle over him at that. The kind of favor that would make Will personally reach out was anything but simple.
He didn't dare press further. He simply nodded several times.
"I see, I see... In that case, sir, what are your plans from here? Is there anything we can help with?"
Kairos shook his head.
"No need. Just have someone walk me out of the Ghost World. That's all I need. Thank you."
"You're leaving already?"
The man paused, clearly not expecting Kairos to be heading straight out into the more dangerous areas beyond the staging ground.
But seeing the resolve in Kairos's expression, he didn't feel it was his place to argue. He straightened up and nodded at once.
"Of course. Right away! I'll take you to the transit point!"
He turned and led the way.
Kairos followed, but after two steps he stopped and looked back at Rex's group, still frozen in place nearby.
All three of them were staring over at him, not quite clear of the shock.
Kairos's gaze passed across each of them in turn, as if something had just come back to mind.
"If you want to get the most out of what's coming, trust me: stay put. Don't leave."
"Something is going to happen in about two hours. When it does, you'll understand."
He didn't linger after that. He turned, caught up with the Ghost World member leading the way, and disappeared into the crowd.
That left Rex, Lena, and Barton standing right where they were, looking at each other.
A gust of wind stirred the dust from the ground and drifted through their somewhat disheveled hair.
"Did he... was he just talking to us?"
Rex rubbed the back of his head, uncertainty written all over his face.
Lena drew in a slow breath, and something sharpened behind her eyes.
"Obviously. Who else is around?"
She bit her lip, clearly weighing it.
"So do we follow his advice, or do we go?"
Barton finally spoke, his voice low and rough.
The three of them were quiet for a few seconds.
The original plan had been to leave the moment their job was done. The danger level here had already pushed all three of them to their limit, and the smart move was to pull out.
But no lengthy discussion was needed. A single look between them was enough to tell each of them what the others had already decided.
In the short time they'd spent with him, the power and quiet mystery Kairos carried had planted something that felt a lot like trust in each of them.
And any person that Will treated the way he'd just treated Kairos: the words that person spoke were not going to be empty.
"We stay."
Rex's eyes hardened with resolve.
"We're already out here fighting Ghosts for our lives anyway. If there's something worth gaining, it's worth the gamble. We're in."
Lena let out a short, quiet laugh. Her Arbok let out a low hiss beside her.
"Fine. Then we stay. I want to see exactly what happens in two hours."
Barton silently pushed his glasses up and nodded once.
The three of them turned together and moved toward the edge of the staging ground, found a spot with a clear view and enough cover, and settled in to wait.
Unconditional trust in that guy.
It was the thought all three of them shared, without needing to say it out loud.
