Naruto: Starting from Summoning the Heroic Spirit Tobirama

Uchiha Kanbaru, who traveled to the world of Naruto, has a heroic spirit system, which can sacrifice various holy relics, obtain skills and noble phantoms that have been sublimated into legends by the heroes of the ninja world, and even summon heroic spirits. Skills [Must-hit Millennium Kill], [Earth Release: Dog Flowing Wall], [Water Release: Tears of an Entire Divinity Space]... Noble Phantasms [Five-Five Opening Duel Field], [The Flying Thunder God Kunai who is always late], [Hashirama's Nine-Nine-Eight Hands Statue]... Until one day, he took the Second Hokage's Thunder God Sword and was about to draw a big one. What appeared in front of him was indeed a girl with white hair and twin tails [Saber], the second princess of the Senju Clan, Senju Hima... Later, Tsunade looked at each other with the almost identical pretty faces of [Caster] girl Tsunade and [Berserker] young Tsunade... The third generation of heroic spirits Kazekage faced off against his own human puppet and dirty earth body... The Sage of Six Paths looked at his old mother who had been 'downgraded' and appeared in a spirit body and fell into deep thought... This ninja world has become insane in a way that Kanbaru did not expect.
