The box was kept within the Celestial World until someone opened it, releasing the Algol, and Inori Hoshimiya. while Celestial Spirit fell to the Japan, and they need Prism Star to make their back to life as a Celestial Spirit.
A long time ago, Makoto's Grandfather sealed all of the Algol along with Inori (Dark Queen the true form of Inori). It was then passed down to the Celestial World and kept within its World until Inori's adoptive father opened the box and released the evils trapped inside. to defeat Algol them should do Prism Constellation together and must return Algol back to Axia Box.
