This event is holodori’s first “Spotlight Event,” featuring five talents—Mori Calliope, Nakiri Ayame, Kureiji Ollie, Himemori Luna, and Ninomae Ina’nis—one at a time across five chapters. Alongside the event, a gacha featuring new ★5 members in swimsuit outfits will be held, while five brand-new songs written exclusively for holodori will be added one by one, each accompanied by an original music video.

This event is a “Spotlight Event” divided into chapters, each focusing on an individual talent. Players can compete for a high ranking in each chapter based on the number of Event Points earned.

During the event, players can earn Event Points and Event Badges by playing Rhythm Game Lives and minigames.
