So does anyone know how to get Naho to be a willing consort without sending her to breaker? I know she Spoiler Alert, tries to kill you if she's not broken first, but I'd prefer having a clothed, Naho than a nude, collored and stitched hands one.
You can't, unfortunately. Maybe there will be an opportunity later. For example, we don't rape her and humiliate in public, we just hold her captive. Then we could convince her to come over to our side and lead the pack into battle for us.
Naho is proud and arrogant. If you break her, you lose the very essence of hers character. Smashing someone is no great performance, any brute can do it. Manipulate her with arguments to get her on your side. To this I say, fit for a king.
