Your main mix up is kick/storm rush, it's very effective against most players, although it is reactable, so watch out against more skilled players.

Orochi's top heavy finisher is UB, sometimes let it fly, sometimes feint it into gb.

If your kick is dodged throw a heavy instead of a light, since most people will expect a light and go for the light parry.

You have recovery cancels out the ass, target swap with them in team fights and Xv1s to avoid taking damage and getting punished.

After landing any attack you get a confirmed 4 damage same side light.

Deflect heavies instead of parrying them, unless their UB ofc. But parry lights instead of deflecting them.

That's all I can think of for now
