Eunie Finds her Husk

When the team finds the ruins of a Keves Gold Rank colony, they search for anything that can be salvaged. Eunie finds a lone husk that had been there for a long time, with its face intact and displaying absolute terror in its last moments. Eunie examines the dog tag and not only finds her name, but begins having flashbacks and nightmares to having been in that battle in her previous cycle.
