Once the appropriate hand sign is done Reika summons an iron cabinet, with a hinged front, which appears beneath the opponent from underground, split down the middle. The cabinet closes around the target and is then wrapped in chains, depending on the situation, Reika can either use it to trap an opponent inside the iron maiden or can drag it back down into the ground once again. She can summon a smaller version in order to trap humans or a much larger version in order to trap creatures of massive proportions.
