Blackout

Spatial Magic: Blackout (空間魔法『ブラックアウト』) is a Spatial Magic spell.

Description
Before activating the spell, the user marks specific areas for activation and destination. After the target enters a marked area, the user activates the spell and a black substance spreads out beneath the target's feet, envelopes the area, and transports the target to another location.

The expanding radius allows for multiple targets to be captured at one time and moved to a singular location. The user can also activate the spell remotely and in multiple areas simultaneously.
