Actually, when you were first offered this, I thought you would refuse outright. Like, samurai honor, loyalty to your home, all that stuff.
Besides, there’s another one lying around somewhere in my inventory; I don’t know what to do with it. If they start disarming people somewhere, they’ll take both anyway, unless I count on it as a backup in case something happens to the first one, but that’s just a possibility. Later, I’ll pump up magic skills and everything will be fine.
