The Nijiyon Animation short anime, an adaptation of a 4-koma spin-off of Love Live! Nijigasaki High School Idol Club, will begin airing in Japan on January 6, 2023. A trailer previewing the Nijigasaki idols’ upcoming activities and their cute chibi forms has been released as well.
The Nijiyon manga by Hito Miyako began in 2018 and has four “seasons” so far. The first two “seasons” were published online as a web manga, while seasons 3 and 4 were released on the Love Live! Series YouTube Channel as a voiced video. Kadokawa publishes the tankoubon volumes.
The main Love Live! Nijigasaki High School Idol Club anime, or Nijigaku, has two seasons, with the first airing from October to December 2020 for 13 episodes while the second aired from April to June 2022 with 13 episodes. Unlike the other titles in the Love Live! multimedia project, the show features the concept of solo idols. The original lineup of Nijigasaki idols was first announced in 2017 as part of the Love Live! School Idol Festival game’s PERFECT Dream Project anniversary project.
Crunchyroll describes Love Live! Nijigasaki High School Idol Club as:
