Ok so, i am gonna try to bring Alexia's best arguments i can muster (trust)
First off, stats is a blantant advantage she has, one good swing means Riku can get his hands chopped off, she has sufficient AP and LS to cut him in 1 swing if she has the chance.
Next, we have speed, how well can Riku deal with someone who is faster than him, her combat speed upscales her travel speed, Riku even with ANPR, IA and reaction is not infallible and would mean he will get eventually overwhelmed sooner or later. Also, i can see from his ANPR scan that he is very susceptible to get overwhelmed by faster opponents
Alexia also has the range advantage with a sword that she can exploit, she can push him back, make him hesitate to get closer to a sword user and possibly even being way to overly cautious which may hinder his fighting ability due to knowing 1 slice is fatal to him, his cautious is a nice advantage to Alexia since she can recover stamina that way too.
Next is magic, Alexia can fuse her bloodlust with magic where Riku has no resistence to it which will definitely hinder his ability to an extent even further coupled with the fact she is a sword user since it works on weaker individuals.
Alexia is also capable of countering even someone who is more skilled than her by a long shot albeit they were holding back, predict suprise attacks and immediately go for a counter, create favorable position to her with acting as she can feign weakness which may make Riku either hesitate or lure him which creates an opening for an counter attack.
Alexia also has IA of her own which allows her to dodge attacks she is not aware, and mabye we can also argue the fact that what Alexia uses to predict attacks would work on phantom jabs because they are unreadable by people who use body movents, rhytm, breathing and attack paths (Alexia uses angle, distance and position of the opponent) so his ANPR resistence is incompatible with Alexia who uses another prediction methods.
She also counters some of Riku's weapons for the match such as;
- Damage reduction because of the sword
- Supernatural willpower is irrelevant if you die by bloodloss
- Pressure points can drain energy faster but gets negated by magic which can fortify her organs
- Information analysis as Riku's ability is to notice weakness which Alexia doesn't have one (no notable weakness LOL)
- Instigating Fear is weak as she has experienced against stronger opponents like Cid (
)
- ANPR resistence is useless as phantom jabs don't counter what Alexia predicts as i said above
