Mandate of Justice

Shota is a high schooler who has all but severed his ties with the outside world, choosing the safety of isolation over the unpredictability of everyday life. His older brother, a figure he once looked up to, has since left home, leaving behind only a peculiar memento: a robot named Rokuro. For Shota, this mechanical companion is a quiet fixture of his reclusive existence—until the day violence shatters the silence of his school. When a deadly armed robbery plunges his classroom into chaos, Rokuro awakens with a startling urgency, compelling Shota to confront the world he has long avoided. With a compelling cry to "save the world together," the robot becomes more than a relic; he becomes a catalyst for change. In moments when Shota's dormant courage ignites, he and Rokuro undergo a breathtaking transformation, fusing into the formidable being known as Xenon Nine. Now, thrust from the shadows of his room into the heart of a crisis, Shota must decide if a reclusive student can truly bear the weight of a hero's mantle. As a new threat looms, the question remains: can this unlikely duo rise to meet their destiny and become the saviors the world so desperately needs?
