A robot named MIRU arrives from a distant future with a purpose: to travel across eras and support people who are struggling. Without weapons, MIRU moves through time, and even into parallel worlds, meeting individuals who keep living with determination despite their hardships. MIRU listens to their problems and helps them get past immense obstacles peacefully, learning and growing with each encounter. Small choices ripple outward in unexpected ways. Conversations shift perspectives. A single moment of courage becomes the seed for something larger, a butterfly effect pushing society toward a brighter future. Across five episodes from five different animation studios, MIRU collects stories about human resilience, reminding viewers that the future isn't something that happens to us. It's built from the countless small decisions we make when we decide to keep moving forward. Behind it all sit open questions about why MIRU was made and whether it can steer humanity away from a dystopian fate.
