Ninja World: I’ve already fought against the Five Kages before the system came

Description

Hagoromo Genzuki traveled to the world of Naruto and became a big figure in the ninja world due to his own efforts.

【60 Years of Konoha】
"It's Konoha Year 2! There's something wrong with your system!"

“Although it’s decades early, we’ve finally arrived.”
