You're completely right, and I'm glad that Anise benefits a lot from this deal. It somewhat justifies ML's actions, at least.
It's just that her saintess powers and her magical beast is the only thing she has to fall back on. She's awfully trusting (she was willing to trust this kind priest with information that could kill her, she told this random stranger (ML) about wanting to become a refugee), and that could eventually come back to bite her.
It probably won't (since this sort of manga probably will never touch upon those plot holes), to which I mourn the opportunity.
This also means that Anise means nothing to the ML if not for her saintess powers. Should she lose it, her life of prosperity and safety is no longer guaranteed. Maybe the ML will be kindhearted enough to let her live a safe life anyways, if he doesn't kill her for knowing too much confidential information.
Not to say that her safe and prosperous life is guaranteed even with her saintess powers. Anise doesn't know much about this world, so the ML could easily fool her into thinking that some other kingdom is evil and manipulate her into agreeing to help Farglow win another war. Anise will think that she's making her decisions with her own will, but she's given faulty information; the decision was never hers to make.
I'm glad someone responded to me. I don't even care about this manga (it's typical trash isekai shojo), but I spent around an hour on that analysis, and it's good to receive feedback.
