please a little bit more information? I would also like to know the manga (=・ω・=)
i think the Manga he means is: http://www.mangago.zone/read-manga/seijo_no_maryoku_wa_bannou_desu/
if it's this one, from what I know is that they are both saintess, it's just that our FL has a higher ability for it. The other girl, from what I know, isn't evil but just pressured because she is currently going through the typical "otome-game-commoner-x-prince" sort of route in the magic academy she's forced to attend. I think in one of the latest chapters with the noble girl explains more.
I am not sure if the other was a saint as well would have to re-read at the other points you are right.
The first comment was just Saints got summond and one was kept out and the other in.
So the first Manga that came to mind was the one i posted it could be that there is another Manga with the setting i dont know.
let be honest, by now there are at least 15 mangas with this concept
It's a good read, the novel is pretty good too. I like this one too, it's shrine princess not saints but good too, http://www.mangago.zone/read-manga/the_white_cat_that_swore_vengeance_was_just_lazing_on_the
Same concept of this other manga that was also about to saintliness that got summoned and one was kept out and the other in. I forgot what it was called at the moment, but in this manga maybe the actual saintliness is evil bc of her chuckle? maybe it will be take a different routeヾ(☆▽☆)
