We've got "2 universes" Earth and the other one.

This other world is composed of at least 3 areas or groups of floating islands.
Heavens
Magical Kingdom
Outsiders area

Heavens is a group of people that restrained their use of akuto
Magical kingdom is a group of people that never restrained their use of akuto

Akuto is their source of power and life. Akuto seems to be limited. So the spartan way of using Akuto is the only way possible for Heavens. That's why they want to eliminate the Magical Kingdom using too much Akuto. By doing this they both reduce the use of Akuto and the needs for Akuto since there's less people/ground/life forms using it.

Regarding outsiders it's hard to know anything, I gave them some land, but there's no way to tell if I'm right. I'll let it at it, since we know only one of this kind... and he seems pretty powerful.


So that universe is some kind of alternate world, placed in earth's sky, without a very feeble connection. But when something as huge/powerful/important as a pillar falls, even that week connection/interaction creates an effect of big proportions in our reality.

For some reasons, people from earth and those guys fought in the past. I wonder how since those worlds have a clear and strong barrier separating them. Maybe that barrier is a result from that fight. Also, all magic/akuto was taken by those from that other world, so I guess they won somehow, when before that power was equally shared.

Munto, our hero, has seen a future of desolation, with a little bit of hope. Opening the futures for the Oracle probably means opening a future where some of the people of that other world live, have a place. Closed futures is when in fact they all disapear with the akuto being depleted. The one needed to prevent everyone of their kind to disapear is Yumemi, the only one we know from earth, able to see that other world. We don't know why but she's important.

Problem, Munto can't live long outside his universe. He's probably there in a buble from his world. But he can't pierce through the membrane... for now I guess.

For some reason I feel like the solution is that earth was originaly the source for akuto. When the other world won the battle, they only got what was stored. Regardless of the amount, eventually you'll run out of power.
So my guess is that the girl will be able to find where the original source of akuto is and how it is possible to have it provide akuto again. And probably both world will be reunited again and the passage beetween both world will be made possible again.

Is that it?
