The teaser visual features Aqua Hoshino at the center holding an umbrella over his head and carrying another in his hand, possibly for the person he had arrived to pick up. Ruby Hoshino could be seen standing behind him facing the other way, holding an umbrella for herself as well.

With that, Oshi no Ko season 3 also revealed its synopsis. Six months after the release of "POP IN 2," thanks to Mem-Cho's efforts, B-Komachi was now on the verge of a breakthrough. Aqua Hoshino had become a multi-talented actor and Akane Kurokawa was on her way to becoming a talented actress.

On the other hand, Kana Arima lost her former cheerfulness after learning about Aqua and Akane's relationship.

Elsewhere, in the quest to find the truth behind her mother Ai Hoshino, and former doctor Gorou Amamiya's deaths, Ruby Hoshino rises through the entertainment industry by using deception as a weapon.

In addition, the anime also announced a B-Komachi live video release decision with a preview video. The preview video showed the B-Komachi voice actors performing "POP IN 2" live on stage. Soon after, Ai Hoshino presented Mem-Cho with the Golden Play Button for Oshi no Ko anime's YouTube Channel. Lastly, Oshi no Ko anime announced a puzzle game and carnival merchandise.
