In the distant future, humans create a robot named MIRU capable of traveling through time, visiting various eras, places, and even parallel worlds. Unlike some robots, MIRU isn't equipped with weapons. Instead, it helps people overcome immense obstacles peacefully, encouraging new beginnings without violence. MIRU continuously evolves by interacting with people, learning and growing to assist those struggling to survive. It listens to their problems and offers support. By helping others, MIRU sets off a “Butterfly Effect,” of dramatic change guiding society toward a brighter future.
