the issue is it wouldn't work with church lore since the church in this game uses womens bodies to clean the filth and sin from the sinners body, as for the belt idea? that wouldn't last since enemies will just rip it off the first chance they get they aren't so weak as to be stopped by a chastity belt if anything they will kill you over it if it were a thing.
no piety exists in noer,its all vicious cannibalism and brutality at all times nothing is sacred
