Hell Blade is a move used by Kazumi Mishima since her debut in Tekken 7. Heihachi Mishima also uses this move in the DLC Story Mode of Tekken 8, though the last hit is infused with lightning.
Description[]
Kazumi performs a jumping left side kick that knocks the opponent off their feet, remaining airborne and followed immediately by a spinning right kick, and finishing by chopping the opponent back to the ground with her left hand.
The first hit must land (either on hit or block) for the remainder of the string to be performed.
This move is essentially Heihachi's Hell Axle with an additional hit at the end.
