This is a story of a man who finds himself reincarnated into Naruto World as Kakuzu, seven days before his death. 

Jiongu, or the Earth Grudge Fear, is a kijutsu that holds a great potential for surpassing one’s own limits. Something that is especially paramount if the reincarnation comes with some unforeseen aftereffects. Considering that his circumstances aren’t that unique and other reincarnatees with special abilities keep appearing out of nowhere, he must make the most of the technique if he doesn’t want to be swallowed by the madness of the new world.
