Creation of the Celestial Heavens

Tentai kōzō is a special technique developed by the Zenhōi kage, who used it to create the Nemesis star and trap the Kuzuryūs' body inside of it.

The user creates a dark black sphere of gravity that, when thrown into the sky, it begins consuming energy from all directions and pulls them into the sphere, at a single point causing it to become super heated. Moments later objects being to be pulled in and destroyed in the process adding to the energy of the star.
