Ryu vs Ayane
Ayane discovers that (or so she thinks) Ryu Hayabusa was in Brazil training, but has since returned to Japan.
Upon arriving at Suzaku Castle, she doesn't find her half-brother's longtime friend, but a different Ryu entirely, which is the Ansatsuken fighter, having returned home from his training with Oro.
Eventhough she is disappointed, Ayane discovers that Ryu is one of three masters of Ansatsuken, the killing art. Seeing this as an opportunity to test out her skills before tracking down Kasumi (once again), she challenges Ryu to a match.
Ryu agrees, and the battle is to take place at Suzaku Castle.
No Ninpo, no ki, just straight power, speed and skill.
Ryu: Third Strike version, AFTER the training with Oro.
Ayane: Whichever's strongest.
