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 can also create multiple Darkness Hermit to seal the movement multiple targets at the same time.

Weakness
The technique cannot be used when there is a lot of light.
