  • All Stories: All of existence are stories. From the inside this stories appear to be truth and from the outside to be fiction. Akuto created all stories that can be described. This includes stories with higher dimensions and without, with time and without time, where the occult exists and where it doesn't and all other sorts of different concepts. Some of this stories contain stories themselves and people like Sai Akuto that can freely create stories. This stories can be called stories of higher story density and can form infinite hierarchies.
  • Void Body: The void body is a state Akuto archived during the final ritual with The Law of Identity. That ritual brought both the stories and Akuto's body down to zero and created a void. During this ritual Akuto and all souls in him are taken into The Law of Identity and together with it they enter the Anti-Universe, the place where all stories end.
