The day you were struck by akuma's raging demon was perhaps the most significant day of your entire life.

But for The Brilliant And Amazing Gamer, the day I landed that blow for the seven hundredth time was friday.

The raging demon, akuma's ultimate attack, also akuma's weakest ultra due to being impossible to land by conventional means.
the psychology behind raging demon is that it's so bad, none would dare to pull it off save for the sake of showing off.
this provides players like me, who heavily use the RD style, with clear openings and even setups that would never be possible otherwise.
take for instance, this situational setup, the hidden demon.

Yo dawg.
