Dark Sakura certainly has some… interesting… attacks. Incredibly, the jiggle is even bigger for Sakura than for Rider, as can be seen in the first link (a complete coincidence, by the way).
And apparently, the last boss for Sakura’s route is Sakura. Wait, what? The other Sakura does a move where the ‘ropes’ that cover the shoulders unlatches, ties the opponent down, and drags them into a pool of Angra Mainyu inky goodness. Then Sakura sort of… flaps around on it like a grounded seal.
Archer does a Rho Aias @ ~1:00 mark. Completely blocks a minor blast from Excalibur.
Very good Archer vs Rider. UBW finisher.
