Dimensional Ascension in the Otsutsuki's Perception

There was no need to doubt it—most perceptions differed from reality.

During this long conversation in space, Kaguya roughly came to understand what the Ōtsutsuki meant by "ascension."

Ōtsutsuki Kaguya had once been a tree planter, just like Ōtsutsuki Isshiki.

They planted God Trees to harvest planetary energy. This Chakra Fruit was never meant to be eaten by either of them, but in the end, even Isshiki developed rebellious thoughts. Before his death, what he told Code was not to hand over the Chakra Fruit, but to devour the countless planets.

For them, the first meaning of this "ascension" was a rise in status.
