Naruto: ordinary people

Haku Ren, a cynical otaku salaryman, awakens as the son of a minor Sand Village noble just before the First Shinobi World War. Stripped of his past life and thrust into a brutal era, Haku possesses only one cheat: an uncanny ability to calculate probabilities and outcomes with chilling precision. He must navigate a world of legendary shinobi and escalating conflicts, where even 'ordinary' people are fodder for war. His goal: not to become a hero, but to survive, protect his new family's fragile standing, and carve out a life free from the endless cycle of violence. But in a world where gods walk the earth, can an ordinary man with extraordinary calculations truly escape destiny?
