Sandman is a Stand User who wields In a Silent Way in battle. In a Silent Way's basic ability is to store sounds in objects or even people. By affecting an object with a characteristic action, like stabbing it, Sandman stores the corresponding sound in the object. If someone touches said object, the sound is released as a hazard characteristic of that same sound (e.g. "burning", "cutting", "stabbing") affecting the thing it has touched. For instance, if a cutting sound is stored inside a ladder, anyone or anything touching the ladder would be cut to pieces. If he needs to direct his attacks, Sandman can create and manipulate artificial constructs out of sounds and the environment. If he affects an object, he can mold it into either an independent creature on which the corresponding sound effect is engraved, or even three-dimensional sound effects similar in appearance to kana. Those constructs are able to move around and, with the right form, can fly to a target to attack them. Unlike the sound storage, sound constructs can selectively affect the object they touch, and like sound make the hazard either go through objects to affect a chosen target directly, bounce against obstacles, or create a constructive interference with several sounds to strengthen the attack.
