Android Maid Concept (Patreon)

In an original, unused plot line for Chapter 2 of Danger Zone One, Reena and Madison were to encounter--and fight--a criminal's personal "maid," which turns out to be a combat android. 

Here's some concept artwork of the android maid (who will likely be featured in a future chapter). 

The artwork here was done by Erwin Prasetya. Erwin's an extremely talented artist who previously worked on Blade Bunny, Monsuno: Combat Chaos, and Shonen King.
