Oh, my, a lot of background characters in this backstory. Well, that is entirely fine~ ... I probably will not be using all of them for major things, though~ XD

"A guard named Vincent who had tried to help them dead". Um. What exactly was Vincent trying to do?

... And yepp, Grado would be the place where one could possibly read to become a Shaman in secret~ ... Though, one WOULD get some odd raised eye-brows if one were to be caught reading some of those books as a servant that isn't supposed to be a shaman. XD ... In any case, secretly a shaman, eh? Well, I'll assume that's a secret that will be coming out soon enough if you intend to fight. Suppose sudden invasions by larger nations does kind of force out that kind of things.

And that... is an excellent usage of the "Quirks/Talents/Aspirations/Other" field. XD

Oh, and the R-button summarization tends to state where the characters is from, so you could fit in "from Grado" in there somewhere. I think. Maybe? Eh, it is a detail.

Yeah, I can see this working. I can most likely think of a reason why a serving girl would be sent along with the party. Not as a leader, most likely, so we still need one applicant capable of that, but it looks entirely fine. Except for that one sentence that I don't really understand about what Vincent was doing, Calico is accepted~!

... Heh... I should go rip the female shaman sprite now, I suppose? Haha...
