Finally, a new Bey for Team Persona, made by Multi Nanairo, is now complete! At Komaba Sushi, which has been given a party setting, Multi, who has been in high spirits since that morning, is joined by Ekusu Kurosu and the others, creating a celebrating mood. To unveil the new Bey, Persona has set up a Star Battle against the powerful Team Phalanx. Takumi Ishiyama of Phalanx believes that he will be no match for Persona, which now belongs to the opposite Tower, so he bets all of his stars to show his determination. This highly anticipated battle, which could eliminate him from the Star Battle, will test the true value of the new Bey!
