Ahhh so ORT isnt the strongest being in Nasuverse after all

Reading Mahoyoru atm and got to this part.

Did some digging after this episode cuz few details went over my head and found out some things

"The Root, also known as Akasha, the Swirl of the Root, the Spiral of Origin, or the Seat of God, is described as the omnipotent, supreme, and *boundless* source of all existence, transcending reality, dualistic function, and all concepts"

.... Isn't Void Shiki the Avatar of Akasha? why everyone keep saying he's the strongest when shiki is deeply connected to the Root?
