Heroine? Saint? No, I'm an All-Works Maid (And Proud of It)! (Manga) Vol. 6

Maika, realizing she's in the same world as her old game, begins working at the Rudleberg mansion in an effort to save the orphanage. But as she watches the head maid, Melody, use her overwhelming saintly powers--to do a really good job as a maid?!--she realizes Melody is the game's heroine. Convinced Melody is the reason for all the inconsistencies from the original story, Maika worries what will happen when the "Jealous Witch Incident" occurs, especially when troubles arise and Luciana is rumored to be the culprit!
