Ten days later, at the edge of the Alternate Space.
Tsunade stood on the gray-white wasteland, facing a slowly closing spatial rift.
Isshiki's remaining chakra had been completely cleared away. Even the stale sense of oppression in the air had vanished.
Kaguya stood beside her, holding a fist-sized orb of dark silver light in her palm.

Tsunade leaned against his
