Corner only. Hit a grounded opponent with a late air Hurricane (HK), immediate Hurricane (LK), reset with early close HK, cancel first hit into demon. If you cancel the HK quickly enough, they’ll land sandwiched between you and the corner. The demon will already have been active for loads of frames and should catch them instantly.
I can’t reproduce this reliably enough to test it properly and the timing and retesting is far too tedious to bothering trying this with programmable input
