"Such an intense chakra reaction. Even from this far away, I can sense such powerful chakra fluctuations. What is that?"
In a corner of the Milky Way, within a galaxy on the edge of an enormous blue star, two Otsutsuki searching for habitable planets looked toward the core galaxy—the one containing the stellar-class super-energy Intellect Brain.
