Memory erasing NPC

Memory Mage is a type of NPC in Lust Grimm that removes your memories of being defeated and raped by enemies.

Description
When you talk to a Memory Mage, you are given the choice of handing over a Grimm Crystal in exchange for their service, or doing nothing. Choosing the first option removes a Grimm Crystal from your inventory and provides three benefits: all memories of losing to enemies are erased, your Lust is set to zero, and your Dependence is decreased by one point.
