I think you're exactly right, it seems some sort of radioactive matter, the case should prevent the radiation to pass through, thus making it not active, for storage reasons. Does not seem to be a life form to me, it's energy(radiation) gives power to what it makes contact, making what the person wishes true. Most really dense elements are man made, so a super radioactive estructure not only can, but should be man made like the hogyoku, and it also explains why the hogyoku needs to be fed, to be radioactive is to expell particles and waves, as such "make yourself smaller" until its no longer radioactive. So to be kept working it has to replenish from time to time
