Can we get a Zantetsuken for DRK's from Odin?

[Alahra]

Everything you just mentioned are arbitrary products of the game's lore. Odin is an actual character from Norse mythology and furthermore has the same incarnation in this game that has followed the previous FF games.

You said the one-handed sword wouldn't work for a job that uses zweihanders, but they've already been using one-handed swords as two-handed swords since DRK was introduced, so that's not a very good argument against the inclusion of a Zantetsuken upscale for DRK. Odin's mythological origins don't have anything to do with that in any way.
