Lacquered Chains Prison (先制必縛ウルシ鎖牢 Sensei Hitsubaku Urushi Sarō?) is a move performed by Shinji Nishiya using the Arbor Quirk.


This move is shot out from a person's arms and forms a wooden prison around the enemy as an absolute preemptive confinement. It takes the enemy by surprise, restricting movement of the enemy at every opportunity.[1] It can also be used to restrain multiple opponents simultaneously.[2]
