So, I was hoping there would be at least some mystery over who Manny was phoning. I couldn't stand to let that mystery run on, though. Sure, I could have had a protracted subplot where nobody knows who Manny's dating (q.v. It's Walky!, Sandman) but I felt it was more important to the narrative and a deeper understanding of the characters involved to show ninjas.

These ninjas do not have Real Ultimate Power. This is due to the Inverse Ninja law; as the number of ninjas increases their effectivenes drops proportionally. Karne would have a hard time against only one ninja. Fighting three - he has a good chance.
