Black Star

Dark Yojutsu: Black Star (闇妖術『黒星』) is a Dark Magic spell.

Description
With an open scroll, the user creates a small black sphere which strongly pulls in the target. This can be used to disrupt an opponent's movements, creating an opening.

The user could also create multiple spheres at one time and target themselves, affecting the trajectory of their own movements and making it easier to avoid their opponents' attacks.
