@DeathGrinx Basically maid regrets a great deal about how she acted at the fight (getting scared and screaming demon lord thing) because she hurt MC even if it was an unconscious thing. She even says something like "I'd trade my life just to undo that moment" if I'm not misremembering it.
After that she decides to apologize and explain to him even if it means to never see him again. She and MC's mother starts to chase MC all over the country but so far they didnt reach him yet. They came pretty close at a moment, almost caught with him, yelling him wait please etc but he got teleported before they could talk.
Some extra note: Apparently she loved main character so much that she thought she'd never leave his side in her life, she even have some books like "how to lead a male person as being inexperienced woman", "how to pleasure man in the bed 101" etc all over her room so she can teach sex to MC when he comes to the age. Also her all "sadistic" thing is an act because she thinks MC loves that kind of woman (she found some erotic books about sadistic / matureish women in his room before). She is actually a pretty decent waifu but I guess it'll take years until mc will be able to realize that.
