How do you get demonized on monster hunter freedom unite

Demonized is only used by a Dual Blade Blademaster
Press "R" to intiate (it raises it's blades high) and deactivate (it swipes both blades to the side). In Demonized mode, you get no Wind Press ( you're unaffected by wind), your attack won't bounce, and you can do the Demon Dance (tri + Cir buttons)
it's a multiple hits faster that tri button smash... it's cool to watch.
