So, with Standard Battle Assumptions in mind, they would start 6 meters away from each other-6 being the average of 10 and 2, which are Kijuu's/Alex's optimal ranges-and then the fight would begin.
What would most likely happen, from looking at their profiles, is that Kijuu would rush down Alex with Blast Rush Turbo, and Alex would use Extrasensory Perception to casually dodge it, then react with a Judo move. Problem is that with Jiu Jutsu, Alex could instantly win the fight by choking her out and breaking her bones immediately after Kijuu rushes in with BRT.
This is what is most likely to happen, so I vote Alex.
