Following the Third Great War, the Uchiha Clan's annihilation sent shockwaves through the ninja world when Itachi Uchiha massacred his own people, ascending to S-rank Missing Nin status. Sasuke Uchiha appeared to be the sole survivor—or so everyone believed. What none knew was that a transmigrator, reborn into the Uchiha line years prior, awakened the Mangekyo Sharingan amid the slaughter. This soul, Seiji Uchiha, forged a deadly promise: avenge the clan by ending Itachi and destroying Konohagakure. Yet his vendetta transcends the ninja world, pulling him across multiple dimensions where destiny demands his wrath. [Prime World: Naruto][First World: Attack On Titan][Second World: DC]
