Thankyou, gentlemen.
Moltex: this is a much trickier task than I thought. I'll keep working on it. Thankyou to RbLcK and Cindermomo. A warm thanks to you, blkk.
I doubt you've seen that opener before, as I made it up while making the replay.

As for the other replay, I've adapted the opener into a punch. That punch follows through to my carrying uke's arm over my head. When that's done, I use the increased momentum of the arm to kick uke's other arm off, and split his torso from his lower body. Once that's done, I smoothly follow up with a smack to the bottom of the severed torso which has enough force to decapitate uke without actually touching his head or neck. It's pretty sweet. I call it m-upper 'cause of the momentum.
