Shadow Bind

Shadow Bind is the Noble Art of Nagi Arisuin.

Description
By stabbing Darkness Hermit into another person's shadow, the user can use it to bind his target's movement. Once activated, it completely seals the target's movement and strength, therefore making it impossible to break upon capture.

Nagi is able to also create multiple Darkness Hermits to seal the movement of multiple targets at the same time.

Weakness
The technique cannot be used when there are no shadows. The user also needs to stab the opponents' shadow, in order to use the technique.
