That situation you described vs. Lambda is pretty much the story of my life haha. Oh, and I also forgot about Renka, canceling random normals into Renka usually catches jumpers. That's probably our best bet. If you're attentive, you can hit confirm that into 623AA for 4.2K, raw Renka is a great starter. If that's too tough, an easier confirm would be Renka, late cancel the second hit into Gurren > hop 5A into BnB for 3.1K (wow, that's a metric fuckton of fighting game jargon, I feel nerdy lol). If you're anticipating that your opponent will try jumping out, the hit confirm into 623AA becomes much easier. That's what my time in the lab has shown.
And the reason I thought it was Kusaregedo was because he has a move that looks exactly like that in the Samurai Shodown games. Ugliest character ever designed.
Edit: Wait, shit, that's only when they're normal blocking. If they're trying to jump out with barrier guard, it's a whole different ball game. Back in the lab we go.
