Myriad Black

Spatial Magic: Myriad Black (空間魔法『ミリアドブラック』) is a Spatial Magic spell.

Description
With an open grimoire, the user manifests multiple portals in front of themselves that connect to portals that have manifested around their target. The user would then fire Magic Bullets into the portals to attack their target from all directions.

Because the portals face inward, the user leaves themselves open to return fire or a direct attack through the portals.
