c.HP my bad
It’s ok & thanks. also in that case, can’t you do something like air to air MP into c.HP, ducking, skyscraper, F.MP>LP, etc… - for setups.
OR
air to air MP into c.HP, ducking, foxhunt, EX / sonic fang. - For damage
or like you said…air to air MP into c.HP, EX / sonic fang - For less complex combos.
I think the air to air counts as first hit and skyscraper only lands in the first two hits. So I doubt it.
edit: best i get off the air to air is j. :mp: cl. :hp: flicker cancel cr. :mp: xx sonic fang
Akuma’s Raging Demon is 0 Frame Startup… 
what does this “Cancelable: SM, EX, SA, CA, Quick Spin” stands for ??
Not 100% sure but I think its "special move, EX special move, super art, cross art. quick spin doesn’t need much of an explanation 
It’s a shame that Capcom made it so that you can get out of kara-demon in this game.
I don’t know if this is in the official frame data or not, but the counter can be blocked when done against meaties. Furthermore, it is extremely punishable on block.
