Notes:

(Taken from the comment section):
Just did rough Google translate. And manage to pick few interesting notes.

1. They used to be servants of Demons of Chaos, but revolt and runaway after gain emotion because of the Demon Lord.

2. Is an incredible maid, her semiliquid body can mimic everything. Problem is, she refuse to use any tool and only her body. Become her master's chair, feed him with spoon made of herself, etc. Eventually he'll realize how good her touch is, and want to "become one" with her. It's clear that they'll have sex, but I'm not sure if he'll really merge with her or it's just feeling they got when he stick his d--- in her.
