Haven't really thought that one through too much. One idea I have is that it's like a Living Shadow of sorts?

Like SMT Persona shadow or absence of light shadow?

At any rate, I don't see anything wrong with an ability that makes a projection of some kind. Though making an autonomous one probably puts you more along the lines of a mage than an esper, even if shadow might be a bit stretching the def. of matter
