Worgan approaches Ryoma for another job. He needs someone to hunt and collect wood from tree-like monsters called treants. They also happen to be one of the types of monsters Ryoma needs to practice fighting against.
Their weakness is the human
face-like lump on the trunk.

Son point faible est sa protubérance
qui ressemble à un visage.
Их слабость — похожий 
на человеческое лицо нарост на стволе.
