The 5th Aipri Contest is coming up soon. Sakura and the others are excited to enter and uncover the secrets of the Aipriverse. Airi has decided that she needs a new song to put her all on the line for the contest. Airi boasts that she will have the new song completed by the next live performance. She interviews the Aipri and the others and expands on the image of the new song. Later, while talking with Mitsuki, Airi reaffirms her dream of "not just performing a live performance, but creating the live performance itself."
