It's a rifle primarily. The hand thing is more of a secondary function anyway.

Yeah his weapon sucks. He never uses it outside of form changes. I figured he might use it as a club in his Specter-form (because of the whole Oni-thing with the horns) but he never does. It just flies out of his Driver whenever he changes into Nobunaga or Tut. Pretty disappointing.

And it just looks stupid too.
