In which case the semblance serves literally no purpose to speak of. They can pass through a solid object, yay, shame trying to do so will shred apart the inside of their body because that's generally what happens when an object attempts to go through another. one or the other gets torn up.

The soul part just doesn't make any sense. their aura doesn't seem to be any different when it's active, only their body is less easily perceived. the soul would be just as easily picked up by whatever sensors (or senses) happen to detect the presence and volume of aura.
