Chimera Researcher is a type of NPC in Lust Grimm. There are five of them, all brothers, who study the succubi. A sidequest involves assisting the researchers in order to gain rewards.

Description
The five researchers are found throughout the world. If you talk to one, they assign you a task. Completing this task causes them to reward you with items, including a key item needed for the next researcher. Only one researcher will appear at a time.
