Naruto: My Sign-In System Steals Everything!

Waking up in the brutal Naruto world, Zhou Yi finds himself cornered by masked Root ninjas, with legendary Hatake Kakashi as his only desperate ally. A civilian with zero chakra and no combat skills, he's just a dead man walking. Until a sudden Ding! announces the \"Sign-In System.\" His first sign-in? With Kakashi! Instantly, he masters the Hatake Blade Technique and obtains the legendary White Fang. But that's not all – every shinobi, every jutsu, every Kekkei Genkai is now a potential power-up, unlocked simply by increasing their 'favorability.' As he slashes down enemies and gathers powers from the likes of Might Guy, his bizarre system promises ultimate strength… but some '100% favorability' rewards are far more terrifying than any enemy, like watching Icha Icha Paradise with Kakashi! Now, targeted by jealous geniuses and shadowy forces, Zhou Yi must sign in or die.
