The one thing that almost does contextualize (maybe???) any of this for Nobunaga is that Klaus also has a personal void when he dies, but without the fish, and instead dead relatives and a God that hates him. So he's sort of imagined the afterlife voids to be a lot like this anyway. Definitely preferable to his own time he calls Hell.

He gives Wayne a merry thumbs up at the axe. "Go get 'em, tiger."

"That's pretty convenient. Die three times, get a weapon upgrade." He wonders if he can get one too. "I wonder if Klaus ever got weapons--" a pause, "Oh, but he did get powers? Maybe that's what he gets in reverse." For killing. And the Vietnam knife.

"Got a strategy in mind?"
