Chou Kaguya-hime!: Second Oshi no Ko Video Is Here
Kaguya and MEM-cho try a call-and-response to "Sign wa B" together this time.

The second collaboration video between the Netflix anime film "Chou Kaguya-hime!" and the TV series "Oshi no Ko" was published on August 2, 2026. In it, Kaguya visits MEM-cho this time and practices the call-and-response to the B-Komachi number "Sign wa B" with her.
As KAI-YOU reports, the second video reverses the starting situation of the first part: previously, MEM-cho was a guest at Kaguya's and guided her through a short self-introduction format. Now Kaguya comes to MEM-cho's room. In doing so, the two pick up an element closely tied to B-Komachi and the live performances from "Oshi no Ko."
Connection Through Music and Virtual Performances
The collaboration builds on the shared themes of both productions. "Chou Kaguya-hime!" tells of a young streamer and virtual live performances, while in "Oshi no Ko" MEM-cho is both a member of B-Komachi and a YouTuber. As a result, the video works not only as a short promotional clip but as a direct encounter between two characters with a similar media environment.
The first part of the collaboration was released on July 26. There, Kaguya had to answer several questions within five seconds but did not keep to the time limit when the topic turned to cooking. The second part was already announced for August 2 at the end of that video.
"Chou Kaguya-hime!" has been streaming worldwide on Netflix since January 22, 2026. A renewed cinema run in several special formats has also been announced in Japan for September 18. For "Oshi no Ko," the "Ichigo Production Fan Appreciation Festival 2026" event takes place on August 16; in addition, a fourth and final season has been announced.
