Oh damn, I think that's just as good or if not better than a trait (it even fits in with the fact my picture has 2 swords).
Yes! Thank you xD

The immune to rusting and extreme heat would be it's be its only specialties and the name meaning isn't literal?
But man, to have such a great sword, exciting. Perfect for kurama. XD

I think Kurama will have a secondary goal now, on the side of attempting to finding zoro and becoming the best swordsman but to collect as many Wazamono err Meito swords!
