Everyone's secret super appears on the command list. It's, uh. Not that secret anymore. :P
I'm p. sure j.B is jump cancelable. j.A is for sure though. D will always desummon Koromaru, regardless of whether or not you're in the air. As for j.B being possible to instant overhead, I do want to clear up that I'm not 100% sure it's even possible yet. This is merely me theory fighting from what I did have the chance to try, and what I saw. If it DOES instant overhead, you can probably follow up similar to Mitsuru with j.B OMC j.B. Or, possibly with a Koromaru move.
Will add these to the list of things to check. Admittedly, most of my time is likely going to be with Ken, but since Aigis has been my main for a while, I can probably at least point out any differences I notice, along with these.
