The automatic glass doors parted with a tired hiss as the smell of overbrewed instant coffee wafted out into the hot afternoon air.
Keiji Nakamura sighed, tugging at the collar of his corporate monkey suit. His black tie was crooked, his ID card hanging loosely around his neck. Thirty-two years old, single, overworked, and underpaid—your average office drone.
He glanced at the sky. Cloudless. Merciless. Much like the real world.
"Another deadline… another fire to put out. But hey," he muttered, his cracked lips curling into a nostalgic smile, "at least I have Naruto and Pokémon to go home to."
On the back of his phone was a sticker of Gengar giving a thumbs up. His lock screen was fanart of Madara Uchiha riding a Giratina.
Yeah, he was that kind of fan. The theory-loving, what-if-debating, power-scaling enthusiast who had shipped Itachi with a Gardevoir in a fancomic once.
As Keiji walked through the building's front plaza, his phone buzzed with a notification. A Naruto fanfic update titled "Madara's Redemption: Rise of the Ghost Shinobi."
Keiji grinned. "Finally, an update—"
THUUUUD!!
The world flipped sideways. A deafening honk. A blinding light. And then... stillness.
"Ah. Truck-kun," he murmured from the pavement, his body broken, blood seeping out in a lazy halo. "So this is how it ends?"

Somewhere Beyond Life…
A giant glowing semi-truck floated before Keiji, its headlights pulsating like eyes. A deep, mechanical voice echoed in the void.
"Keiji Nakamura. Otaku. Workaholic. Ghost-type Pokémon fanatic. Uchiha Clan admirer. You have been deemed worthy."
"Of… reincarnation?"
"Yes. Your obsession has been recognized by the Multiversal Karmic Bureau. You will be sent to a parallel world. One you love: the Sengoku-era Naruto timeline, before the founding of the Hidden Leaf."
"Wait, you're real?" Keiji gawked. "Truck-kun is real?!"
"Affirmative. Also... I read your biodata."
"W-Wait! Don't look at the Gardevoir folder—"
"Too late."
"…damn."
"Regardless. You shall be given a Pokémon-based System. However… there is a catch."
Keiji raised an eyebrow. "There's always a catch."
"You will only be able to use Ghost-type Pokémon. Your role is to distribute Pokémon of all 18 types various ninja clans to influence history… But your own power shall be confined to the spectral type."
"So… I'm the Ghost pokemon champion. Cool."
"Additionally, you will reincarnate as the orphan grandson of a banished Uchiha elder—Madara's grand-uncle. A forgotten bloodline. Hidden in the mountains. Survive… and spread the Pokémon influence."
Keiji's eyes gleamed with passion. "Do I get a starter?"
"Of course."
A purple Pokéball floated before him, marked with a sinister shadow aura.
"Choose wisely, Ghost Tamer."
Keiji grinned as three spectral options appeared before him:
Gengar – Mischievous and terrifying. Shadow Master.
Mismagius – Hex-casting queen. Enchanter.
Drifblim – Carrier of souls. Silent wraith.
He didn't hesitate. "Gengar. Always Gengar."
"So it shall be."

Land of Fire – Sengoku Era
Keiji blinked as the sun warmed his face. Gone were the stale lights of his office, replaced by a brilliant blue sky and the scent of wildflowers.
He sat up slowly, noticing his smaller frame. His hands were lean, fingers calloused. A cracked mirror nearby reflected his youthful face—messy dark hair, sharp onyx eyes, and faint tear troughs beneath them.
"I'm… twelve?" he muttered.
He looked around. A small mountain hut stood behind him, surrounded by forest. Training posts, kunai marks, and a water barrel indicated a shinobi lifestyle.
"You're awake," croaked an old voice.
An elderly man sat on a rock nearby, wearing faded Uchiha robes. His eyes were blind but alert.
"I… I'm Keiji," the boy replied instinctively, following the system's prompt in his head. "Keiji Uchiha."
The old man's face twitched. "That name… I am Renga Uchiha. Brother of Arashi Uchiha. Grandfather to Madara and Izuna's father. Banished for opposing the clan's methods."
Keiji's jaw dropped. He'd read obscure lore about a 'Renga' in a fanbook theory once. A pacifist among warmongers, exiled for refusing to kill children in a raid.
Renga looked into the distance. "My son… your father… died young. As did your mother. You are all that remains."
Keiji felt a flicker of emotion. This world… was real. So were its losses.
"I will train you, Keiji. But beware—the era is cruel. The Uchiha and Senju kill each other like wolves. You must learn to survive."
DING!
The system interface opened in Keiji's mind like a holographic scroll.

Keiji whistled. "So I'm basically a Pokémon-themed Sage of Six Paths… if I live long enough."
DING!
Gengar has been summoned.
A violet vortex of mist swirled beside him, and from it emerged a grinning shadow creature, its red eyes gleaming with excitement.
"Gengarrrr!"
"Holy sh—you're even cooler in real life!" Keiji gasped.
"Gen-gar~" it smirked, floating around him playfully.
"Let's do this, buddy." Keiji grinned, fists clenched. "We'll haunt this world in style."
