An ordinary ninja from the same generation as the 6th Hokage finds himself at a loss on how to continue moving forward after his hope of living in "Peace" was shattered by the appearance of stronger foes. From the moment he was born, and experiencing the 3rd Great Shinobi World War, and the 4th Great Shinobi World War, and other big events that happened in Konoha like The Nine-Tailed Demon Fox's Attack, Konoha Crash, Pain's Assault, and more. He, with his undying tenacity, survived every hardship thrown in his way, surviving, surviving, and surviving; however, every time he survived, a loved one passed away. When the 4th Great Shinobi World War ended, and the emergence of stronger Konoha shinobi's and improving relationship with other Villages, a growing hope of finally achieving "True Peace" had taken root inside him.
After the 4th Great Shinobi World War ended and "Peace" was achieved, the man retired and eventually married and even having three kids. Years passed, and this peaceful life continued, spending time with his wife, and watching his beloved children grow up. Until eventually, conflicts appeared more often, and even grows harder to resolve, which led to cracks appearing in the unwavering belief of achieving "True Peace".
Despair took over when even the Almighty Shinobi who ended the 4th Great Shinobi World War and protector of Konoha barely able to stop the invasion of enemies. This despair was further deepened when the 7th Hokage disappeared, and eventually, the growing conflicts took everything from him. The man became lethargic and thoughts of ending the suffering appeared, but alas, he was a man "cursed" to live. He was once again alone, and at the same time surrounded by loved ones. The man, once again, held his sword, and fought, however, surviving is no longer the priority, now, every fight he fought will be to protect.
Years of fighting, pushing everything he had to it's limit, and went further beyond to protect the remaining survivors, the man achieved a power he never held before, a potential buried by his ordinary talent. He who guides the last remnants of civilization of the shinobi world alongside the few old folks from past times and the new generation, struggles to reclaim a foothold in the "New World".
The eventual return that changed the future. With the existence of the Otsutsuki's, the appearance of multiple unknown race, the monster's native to this world, to the demon worshippers, and even the jashin believer's and other cultist groups sowing chaos and destroying order. All this was brought by the expansion of the world, together with the awakening of an ancient civilization.
This is the journey of a man cursed by "immortality".
