Just to explain a bit; It’s the actions that make it “humiliating” or otherwise. Bayonetta could have simply used a downward air attack (or side air attack) to finish it, or other such less-flashy overdone thing.

Instead, Bayonetta waited for Ryu to use Up-Special (Shoryuken) then countered, thus slowing time, then…

For anyone wondering, it’s at 43:04 on the video link.
