Oliver is first seen when he informs the newcomers about the upcoming hunting game that takes place in Goldy Pond. Oliver telling Emma that he wants to destroy Goldy Pond. This made him decide to form the Goldy Pond Resistance in order to destroy Goldy Pond and defeat the demons. He also holds a strong grudge against the Poachers for all the harm and bloodshed they caused. Oliver appears to be a strong-willed person who cares deeply about the well being of his comrades. He wears normal clothing that seems to have little to none weight, for example, his blouse. This was seen when he opened his blouse to show Emma his number, AII899-890 on his chest. Oliver has messy white hair with a red streak on the left and red eyes.

Together with Lucas, they formed a resistance organization to destroy Goldy Pond and the Poachers. There he met Lucas, a survivor of multiple hunts and became his agent, he learned the truth of the two worlds, demons, the promise and so on. Sometime in the past, he was moved over to Goldy Pond by Grand Duke Leuvis to be hunted. Not much is know about Oliver's past, but it is revealed that he grew up in the Grand Valley orphanage just like most of the children living in Goldy Pond.
