Both lives so far, the encores would start with a buildup to Tenkyuu with a pulsating star in the center. After Stellar Stellar there's these two stars that fly from the crowd towards the stage. The Budokan live is called Supernova. There is a type of supernova (Type Ia) that occurs in binary star systems to create critical mass.
