Starting as a working person from Naruto

In the fifty-fourth year of the Konoha Calendar, two extraordinary prodigies rise through the ranks of the village's elite Anbu black ops. The first is Uchiha Itachi, a young shinigan whose brilliance is matched only by his absolute devotion to his home. He operates as a willing instrument of the Hidden Leaf, prepared to sacrifice anything and cross any moral boundary for the sake of Konoha's stability—with one single, unbreakable exception: his younger brother, Uchiha Sasuke. For Itachi, Sasuke remains the sole untouchable sanctuary in a life defined by ruthless duty. The second genius is Akihara Kagura, a figure who mirrors Itachi's lethal efficiency but carries a far more chilling philosophy. While he also styles himself as a mere tool of the village, his dedication knows no limits or boundaries. Unlike his peer, Kagura is entirely willing to pay any price demanded by Konoha's survival, including the life of the very person Itachi holds sacred. This stark contrast sets the stage for an inevitable and tragic collision between two brilliant minds—one bound by a singular love, and the other liberated from all attachments.
