Forest of soul slave 2

A few years after Colt entered the forest, the originally weak Philum also became an adventurer after recovering.
In a tavern where she stayed, Philum heard that Colt's last direction was "Slave's Forest."
In order to track down her sister's whereabouts, she also headed towards the forest—

But what greets her in front will be her sister, whom she has not seen for many years, or perhaps more...desperation…?
