Well, shoot. I kinda wanted to try the Giant Swing again since it worked really well the first time, but I've been dwelling on it and I think the lack of forward momentum is going to ruin our chances at it (at least in the short term). Gonna try something else.
> Put up our arms and fists in front of us in a defensive stance. Tilt our torso slightly so our left shoulder is out on front and our right shoulder is behind, if we have the time.
> As the oni throws her punch, lean sharply to the left, and attempt to block the punch by pushing on her punching arm from the side. Use both hands, and push her arm away from us to our right, so her momentum carries her fist (and hopefully more of her) past us. Aim as far down the arm as possible; shoving at her wrist would be ideal.
