I'll just dream an ending up, then. I can't imagine Endo and Verde with anyone else other than those two. I'm very sure, however, that if Higuchi and Gorou die someday, they'd never be forgotten.
Guys imagine it like this: If demons and what-not exist then other supernatural beings must exist right? Liiiike lets say...spirits...who are just dead humans...that live forever...soOOOOO when they die they'll just live with them as spirits!! Or they can wish for themselves to be demons also possibly.

OMGGG WHEN THEY DIE AND WHAT WILL HAPPPPEN?????????// NOOOOOO
