A mother dog breaks her chain to stay with an old man buried in rubble after an earthquake takes everything. The OVA doesn't ask you to feel sad about it, it just shows you a creature choosing to be present when presence is all that's left. Mari survives what destroys her world, not because the story needs her to, but because that's what living things do when they love someone.
A mother dog named Mari faces an impossible choice when a devastating earthquake collapses her home in a remote mountain village. Her three newborn puppies depend on her, but so does the elderly man who raised her, now trapped beneath the rubble of his own house. With her chain broken and instinct driving her forward, Mari becomes the old man's lifeline, staying close to comfort him through the long hours before rescue arrives. When help finally reaches them, survival comes with a cruel cost. The man who loves her cannot keep the dogs, leaving Mari and her puppies abandoned in a village that's rapidly emptying as residents flee the aftermath. What follows is a quiet, unflinching look at resilience and maternal love in the face of natural disaster. This is not a story about miraculous rescue, but about ordinary creatures enduring extraordinary loss. It asks what happens when safety means separation, and how the will to survive persists even when everything familiar is gone.
