[No System + One Heroine + Slow Growth + Somewhat Overpowered + Classic Uchiha Sharingan]
On the battlefield of the Second Shinobi World War, a young man with a five-tomoe Sharingan steps out of prison.
Fire and sword become his calling cards.
Orochimaru is his comrade, and Kakuzu will become his subordinate. Starting in the Land of Rain, he gradually rises to prominence.
He battles Hanzo of the Salamander and fights alongside Hatake Sakumo against the Hidden Sand, leading Konoha to victory in the Second Shinobi World War...
A gleaming white blade, a pitch-black robe, and a young man roaming the shinobi world,
setting out to witness the resolve of its people!
[PS: I'll do my best to make it thrilling. There may be some angst, and I'll introduce a character not in the original story early on to flesh out the plot.]
The writing is a bit messy, but the plot is good
