When performing Blade Rush, Shade walks up in front of her target and activates her Leech Blade on her right wrist, creating a purple, shimmering energy blade. Shade then jumps up to the enemy and delivers a deadly combo of slashes with her Leech Blade at the opponent. During this combo, Shade first throws a horizontal slash to the right, then horizontally to the left, and finishes by jumping into the air and bringing her blade down on the opponent vertically, pulling her whole body weight into the strike. After completing her combo, Shade jumps away, and retreats to her party.
In gameplay, Blade Rush deals attack damage to a single target with three strikes. When it deals damage, Blade Rush inflicts Leech on the target. The higher the level of Blade Rush is, the more attack damage it will deal.
When performing Blade Rush in gameplay, the player has to complete a series of real-time events, by performing certain actions on the Touch Screen, in order to execute Blade Rush optimally. The same real-time events also occurs when the player can choose to dodge Blade Rush when the move is used against the player (such as when facing Shade in Blue Ridge Zone and some of the Gizoid-type enemies):
The player has to touch the inside of two circles in succession when the outer circles overlap the inner circles.
The player has to touch and stay inside the outer circle that appears when it overlaps the inner circle and follow it in a straight line from the upper left corner of the screen to the lower right corner.
When the player is using Blade Rush, missing or not touching these circles correctly will either result in Shade missing a strike or the damage from the attack being reduced. If used by an opponent against the player, however, missing or not touching these circles correctly will make it more likely for the opponents to hit the player's character.
3 x 150% of Attack damage
3 x 175% of Attack damage
3 x 200% of Attack damage
Despite the in-game description saying that Shade does a five-hit combo when using Blade Rush, Shade only attacks the opponent three times in gameplay when using it.
