Having traveled through the ninja world, becoming a ninja without a bloodline, a clan, or talent, Aoshu looked at his bloodline simulator. Heartbroken, he gnashed his teeth, seeing the disappointment of his bloodline ancestors! Change! It must change! Starting with my "father," who chose to be a carpenter instead of a ninja! Years later, Aoshu stood atop a stone statue in the Valley of the End, overlooking the ninja world, and said, "From the Six Paths Sage to the present, the history of the ninja world is vast, but it can be summed up in four words: bloodline limit!"

He traveled through time and space and became Namikaze Raimon, the elder brother of Minato Namikaze. He was resurrected by Orochimaru during the Chunin Exam. The man who made the ninja world's anus tighten has returned to the eyes of the world!

Ohnoki: This guy kicked my kidney!

Edo Tensei Tobirama: I withstood a blow from the Steel Gate Ripper! Don’t you think I’m awesome?

Namikaze Kaminarimon: It's normal to feel dizzy and it's normal to have a sore butt. Take a deep breath and relax!
