Something tells me that Isshiki's ability to shrink himself and other things aren't actually his abilities, but Jigen's. I'm guessing that this is something like Jigen's kekkei genkai and that probably when an Otsutsuki gets a vessel, it gets its ability as well. It just doesn't seem to be an Otsutsuki ability.
