Transmigrated into the body of a marginalized Uchiha youth in Konoha, Jin has no desire to become a hero, save the village, or awaken the Sharingan—his only goal is to survive quietly. After years of being distrusted by both the Hokage’s faction and his own clan, he’s resigned to a life of obscurity—until a lazy, sarcastic 'Lying Flat and Slacking Off System' awakens inside him. Now, every time he does absolutely nothing, his chakra, ninjutsu, and taijutsu automatically level up.

While his classmates train relentlessly and the village prepares for war, Jin spends his days napping at Ichiraku Ramen, avoiding missions, and ignoring the growing tension between clans. But his unnatural calm, uncanny skill growth, and refusal to engage have begun to confuse even the legendary Kakashi. As the village hurtles toward conflict, Jin’s 'laziness' becomes the most dangerous anomaly of all—because the system rewards him not for fighting…

but for refusing to fight at all.
