World Teacher

Sirius was widely regarded as the most exceptional special agent of his generation, a man whose skills and tactical brilliance were unmatched. His life, however, came to an abrupt end when he sacrificed himself in the line of duty to ensure the survival of his comrades. Rather than fading into oblivion, he awakens to find himself reincarnated as a young boy in an entirely unfamiliar world, granted a second chance at existence far removed from the battlefields of his past. Despite this miraculous rebirth, one profound regret from his former life lingers: he never had the opportunity to mentor a successor. Sirius had always dreamed of passing down his hard-earned knowledge and experience to a worthy student who could carry on his legacy. Driven by this unfulfilled ambition, he resolves to seek out individuals in this strange new realm whom he can mold into capable pupils. Thus begins the extraordinary journey of history’s greatest special agent, not as a lone operative, but as a dedicated teacher and role model. Embracing his new purpose, Sirius reaches out to those struggling to survive, offering them guidance and strength. “If you have nothing to lose, follow me! I will teach you how to live in this world!”
