Survival: Another Story summary: A Survival side story, set between the events of chapters 76 and 77. While travelling on his journey Satoru comes across a boy drowning in a river. He attempts to save him, though is swept away by the current and loses consciousness. Upon waking he finds himself in a mysterious city ruled over by a cruel tyrant.
