"He actually has two Yonko-level executives!"

Chu Tian was originally a powerful figure in a parallel world on Earth.

Straight to the point of being completely straightforward!

On this day, he transmigrated into Hinata's body from "Naruto".

Hinata it is!

With its own system, it can grow bigger and stronger, and create new glories.

However, when he opened the system, he was immediately shocked!

This is a favorability system, and it's automatically linked to Naruto!

How could someone as powerful as me possibly be paired with Naruto?

However, the system provided the skill template for "Five Wise Insights"!

How could a mafia boss like myself be just a lowly henchman in this land?

And so, Naruto! Here I come!

...

"Naruto, don't do anything reckless! We're just friends!"

"Kiba Inuzuka, when did you start liking me?"

"You are the challenger."

——————

Demon Slayer World:

Muzan's face was filled with resentment as he growled at Oggs, "Damn it... if there were no sun..."

"Okay then."

"If I blow it up, you'll be able to fight me, right?"
