Bonus pic: Mamako Oosuki [Sketch] (Patreon)

A combination of several suggestions!

Mamako attends a quest with her gang, but is lost when she chooses a different path. As she walks through the pathway, she was ambushed by higher level Goblins. Apparently, that pathway was intended for high-level players!

Easily defeated, the Goblins restrain her and clad her in some unique maid accessories! Apparently, these Goblins enjoy having their captives serve them. Mamako seems to rather enjoy it... Well, she's making use of the situation until her son saves her.
