This is probably more representative of Tao vs. Ara then either of the last 2 videos. Note some of the key points in the fight:
-Tao wants to get out of curse as quickly as possible, or she will get destroyed. This is why Keita will burst at the end of combos so that the curse will not hit him.
-Ara's 2B can catch Tao in the air. (Hima oftens uses it as an anti-air against Tao.)
-Dive will often beat Tao's drive.
-Ara does not deal with Tao pressure well. Corner pressure hurts a lot unless Ara can tele out.
-Tao's 2D and j.D can also lead to big damage against Ara. j.D can also thread through some of Ara's zoning.
So, we can see that Tao vs. Ara without curse is pretty even. Both sides have the tools to dismantle the other.
Tao vs. Ara with curse, however, is heavily sided in Ara's favor. Tao simply can not handle the constant pressure curse brings, and has to look for a way to poke out.
