Oshi no Ko Anime Behind-the-Scenes Documentary Revealed
The anime staff has offered an explanation for why the first episode of the Oshi no Ko anime is 90 minutes long. According to producer Shimpei Yamashita, the team is comprised of avid fans of the manga and did not want to cut any important scenes or dialogues just to fit the standard anime format. Director Daisuke Hiramaki added that they agreed early on to create a longer episode that could be broadcast as a TV special or shown in theaters, rather than splitting volume one into multiple episodes.

The staff also received significant input from the manga’s creators, Aka Akasaka and Mengo Yokoyari, particularly regarding aspects such as character designs and background art. The creators provided additional context for many of the design choices in the original manga, such as the reason why certain characters have stars in their eyes. While fans may be curious about the significance of these stars, the anime staff has chosen not to explain it for the time being.
