Well, we don't know if the Vandenreich have a Mayuri counterpart who could be responsible for creating it, and if he does exist, how smart he is and what resources he has, so yes, could be completely artificial, part soul/shinigami, part hollow, human, god-knows-what-else. And if he can, or has, built more! The single eye could be interesting; it's not a design cue that anyone's had previously, so I've no idea as to what it could signify. And we still don't know what the 'K' stands for. DAAAAYM!

Now, Bazz-B. I'm in the camp that says he's not at Yama's level; if he were, he'd come away without any damage from that. It seems he didn't, so I'd wager that Ryujin's flames are still more powerful, and by quite a margain. But still, the uniform is pretty jazzy, so no matter what happens, at least he'll look stylish.
