Kazemi Sento had always lived in his own world.
Whether he was at school, home, or on the train, his mind was busy cooking up fanfiction plots, writing crossover matchups, or pretending to be his favorite anime characters. His classmates thought he was weird. His parents were worried. But Sento didn't care. As far as he was concerned, reality was just a boring interlude between sessions of pure imagination.
That is, until the day reality decided to punch him in the face… literally.
One moment, he was typing up a Naruto crossover fic in his room, and the next—BAM!—a blinding light swallowed him whole. When he opened his eyes again, he wasn't in his bedroom. He wasn't even in his world.
He was lying in a bed. Not his bed. The ceiling above him was wooden, not plaster. A breeze filtered in through an open window beside him, carrying the scent of flowers and distant smoke. Outside, he heard voices—people speaking Japanese.
And then it hit him.
"Konoha…" he whispered.
Sento sat up so fast he nearly blacked out. He looked around the room—clean, simple, traditional. He darted to the window and looked out.
There it was. The Hokage Rock. Carved faces of Hashirama, Tobirama, Hiruzen... even Minato.
"No way… no friggin' way." Sento was in disbelief.
This wasn't just a dream. He was in the Naruto world.
Before he could scream in excitement, a blue screen popped up in front of his eyes like a digital game interface.

Sento's jaw dropped. "NO WAY. This is like those isekai novel I've read before."
He clapped his hands together, eyes gleaming. "Alright! Let's do the ten-pull!"
The system interface opened a spinning gacha wheel. Bright lights. Glowing runes. Intense drum music. The wheel spun.

Sento stared at the results, blinking. "Wait, I summoned all of Team RWBY?! That's amazing… but also kinda weirdly specific. Did Monty Oum bless me from beyond the grave?"
"But what about the bonus reward" Sento checked the World Editor Token and the description blew him away.
[1x World Editor Token – Allows you to edit core rules of the Naruto world. Use wisely.]
Sento mind exploded with ideas. He could rewrite bloodlines, change genders, fuse chakra and Nen, make Jiraiya a woman for the memes, or turn Orochimaru into a misunderstood anti-hero snake dad.
But for now, he filed that away. First things first—check his new summons.
A glowing circle appeared on the floor, and with a burst of light and rose petals (of course), four girls stepped out—each wearing their signature outfits.
Ruby blinked and looked around. "Uh… guys? This doesn't look like Remnant."
"Definitely not," Weiss muttered, hand already on Myrtenaster. "Did we get teleported again?"
"Okay, this is getting old," Yang said, cracking her knuckles.
Blake just narrowed her eyes. "Who summoned us?"
Sento stepped forward, arms wide. "Greetings, mighty warriors! I am Kazemi Sento, the Great Summoner, and you now serve under me in this amazing world of Shinobi!"
Team RWBY stared.
Yang raised a brow. "Is he… roleplaying?"
Blake sighed. "Yep."
Weiss pinched the bridge of her nose. "You've got to be kidding me."
Ruby, though, smiled. "Well, at least he seems nice?"
Sento cleared his throat and dropped the theatrical act. "Sorry, sorry, I'm just excited. You guys are my favorite characters from RWBY. And now you're here. In Naruto. With me. This is the ultimate dream come true!"
A small bell sound rang in the air.
[Summons Registered
All summoned characters are now fully loyal to Kazemi Sento.
Synchronizing power levels…
Adjusting to Naruto world physics…
Done.]
Sento's heart raced. "Wait. Adjusting power levels? Does that mean…?"
He turned to the girls. "Ruby, how fast are you right now?"
Ruby vanished in a blur, reappearing behind him in half a second. "Pretty fast."
Sento grinned like a maniac. "Yes. YES. My team is cracked."
A knock came from the door.
"Excuse me, Sento-san," a woman's voice called. "The Hokage has requested to meet you. Please come to the tower when you're ready."
Sento stiffened. "The Hokage? Already? Crap. I'm just some random civilian in this world. I need a backstory. Something that explains why I have four powerful kunoichi with me!"
He paced the room, thinking fast. Then he snapped his fingers.
"I got it. I'll say I'm a wanderer from the Land of Iron, trained by samurai monks. And these girls are elite warriors I rescued from a forbidden science experiment gone wrong. Yeah, yeah. That'll work."
Ruby tilted her head. "Isn't that kind of lying?"
Sento looked at her seriously. "Ruby, this is the Naruto world. Everyone lies here. It's like breathing."
Weiss rolled her eyes. "Ugh. What did we get ourselves into…"
[Or you can use the World Editor Token]
"System you are a life saver!" Sento exclaimed as he use the WET to register team rwby and his info in konoha database.
"From now on you four are a clan of samurai that lived in land of iron but moved to Konoha to become a Shinobi clan, while I'm a ordinary civilian living in Konoha" Sento declared as the WET disappear after use, he need to get more of WET, now that he knows it usefulness.
(A/N: Sento won't be appearing much, he will do behind the scenes stuff in the dark, while the summon characters will be in light and active)
