As Mimori awakens from her fever in the hidden temple and undergoes procedures with Tsubasa, Ushiyama reveals to the understudies that the next concert will celebrate Mimori's debut as a successor. Whilst happy for their friend, the girls become anxious as to whether or not Mimori will change from becoming a successor. Elsewhere, Mikako is seen contacting Chieri's father about how to initiate the Center Nova phenomenom. Meanwhile, as Minami gives some encouragement to Kanata, who is secretly downhearted about being the only 75th gen successor left, she learns that Kanata had a fever similar to Mimori's a while back. This leads her to speculate that Kanata was initially supposed to become the next Takamina, but was unable to because of her. When asked what she would do in such a situation, Kanata responds that both Minami and the name of Takamina are important to her. As the day of the concert arrives, it is revealed that Mimori has inherited the name of Mariko Shinoda that Tsubasa previously held. After her debut performance, Mimori brings Kanata on stage to reaffirm their promise to both become successors. Meanwhile, Mikako informs Chieri's father of the three conditions required for initiating the Center Nova phenomenom, who arranges the DES Force to launch an attack on Akibastar.
