Dark Release: Rasenshuriken

By infusing his Dark Release onto his Rasenshuriken, Onryō Oni can create a darker, and more sinister, variation of the Rasenshuriken.

After travelling a certain distance or colliding with a target that it can't slice through, the central sphere of the Dark Release: Rasenshuriken detonates, producing a vortex of shadows in the immediate area. Unlike the original Rasenshuriken, however, Onryō's version simply causes exterior damage rather than on a cellular level, which in turn, also gives Onryō the advantage of not taking the risk of damaging his own.
