I’m an NPC in Naruto! Ninjas as Players!

Shiroishi traveled through the Naruto World and became an NPC. He could give missions and rewards to the native ninjas to become stronger.

"Ding…Tsuneo has completed the quest. Reward: The color of the equipment is domineering!"

"Ding…Orochimaru has completed the quest. Reward: One Pirates World Crossing Card!"

"Ding…Kakashi has completed the quest. Reward: Breath of Thunder!"

He also used the dungeon’s function to continuously let people discover the secrets of Ninja Realm.

In the Dirt of Death Instance Dungeon, Kakashi discovered the truth behind Dirt’s survival.

In the Night of Extermination instance, Sasuke understood the truth of Uchiha’s extermination.

In the Night of Nine Tails instance dungeon, Naruto knew his identity.

Akatsuki had organized a dungeon, and Nagato knew that he had been dragged into a pit.

The countless dungeons made Ninja Realm have no secrets.

This was a story of an NPC disrupting the ninja world and even more worlds.
