[In The Flesh] is a close-range combat-type Stand with the ability to seal away a target's consciousness behind a cognitive brick wall, an effect which is outwardly depicted by the target's body becoming covered in masonry lines evocative of such.
Rather than an immediate effect, The Wall is put into place a few bricks at a time with each successive physical attack that makes contact against the target -- although what constitutes a "physical attack" is open to the user's interpretation, potentially including use of projectiles, pre-established traps, or other tools/weapons. However, this effect's accumulation can only be applied to one target at a time.
Once Kuyo considers The Wall to be "complete" at his discretion, the target is locked in a comatose state until they're able to break free or escape, which means they must either break down or climb over The Wall in their mind without the aid of any supernatural powers. This becomes increasingly difficult depending on how many bricks are in The Wall.
While the target's mind is locked out of controlling their own body, said body instead can be used by Kuyo as an extension of his own with simplistic programming.
However, the psychic connection this effect creates means that Kuyo experiences a percentage of his target's thoughts, feelings, and memories until The Wall is "complete", up to and including phantom pain of any damage he may happen to inflict on them in the course of battle. For this reason, Kuyo despises using his Stand except in the most dire of circumstances.
