The Center Nova is the position held by the member of AKB0048 considered to be the star of the group, with that extra special idol spark that makes them stand out from the rest by making the kiraras gather around them while performing. There is a special wall in the dormitories of the AKB0048 house where the past Centers all have a photo. All the centers have graduated, however, they graduate by disappearing, or running away (such as in Minami Minegishi the 5th's case). No one knows their whereabouts after they all graduated. The Center Nova is also called the Position 0, and there is a special part of the stage for them. It also appears in the opening of Season 1.
Up until the departure of Acchan, the group always had a Center. As Yuuko explains to Nagisa and Chieri in Episode 5, on their day off, the position was retired after Acchan's departure due to the rampant rumors that flew fast after Acchan disappeared. However, in Episode 10, Yuuko also explains that the Center Nova position was retired once Mariko Shinoda the 7th graduated and joined the administration. This occurred after Acchan's disappearance.
It was later revealed in Episode 25 that the idols are warped to a theatre where they perform and create the songs that are then sung by the members of the AKB0048. However, for those who did not acquire the true Center Nova spirit are stuck in a state of limbo; unable to return and unable to ascend to the top.
The Center Nova, who have reached the ultimate radiant disappear in the "other world". There, they sing forever, to illuminate the shadows in the heart of everyone, so the hope which is brought by the Entertaiment, never disappears.
