What would happen if he got .. say, decapitated? Or pulverized to smithereens. Will he die?

Spoiler for answer:

If he dies, he's dead. The regeneration ability only works on people who are still living. And in the case of Tatsuya, he himself can't die. He could be within a step of death, but as long as he doesn't die, he'll auto-regenerate. If he at any moment of time actually dies, he's done.
