We know that ralsei is a darkner, but we never get to see his object in the real world.

I think Ralsei's object is actually the air itself, i mean it would explain how ralsei could explore the dark world easily and since all the air is technically just one air, that explains why ralsei is the same in all dark world.

His fire ability can also be an attribute of air (oxygen) he ignite fire using air.

Also ralsei float, so that is another reason i think

What do you think?
