Facing the impending night of the massacre, an ordinary person could only tremble in fear. But the protagonist set his sights on the old man about to personally destroy the Uchiha—the Third Hokage, Hiruzen Sarutobi! Since Fugaku Uchiha couldn't stand against the Konoha higher-ups, let Hiruzen Sarutobi himself become the Uchiha clan head!
