There's some content for that. If you have enough Magic, you can make a Request to try Magic reversal, and it lets you dominate her.After beating Alma in the mansion she basically becomes MC's servant (he lets her live and she gives up some money and joins the party). But interactions afterwards doesn't make it seem this way. Interacting with her in the camp leads MC to becoming her toy and dominating him. I feel like this should be an option, but not the default. Will there be content where MC makes her service him instead of the other way?
When you first meet Alma and decide to rush into a fight, with high enough Magic you can also make her submissive, and the scenes are different.
I do agree that Alma's role as servant is kinda thrown away right away. Because it seems strange that a master would ask a servant what does she want, and get a list of smug requests. While she's very rarely admitting she's working on you. It's strange that she even proposed to serve then. But of course most of players would want it to still be this way.
