22/7

''The wiki is mainly focused on the Seiyuu and the music. For more information on the project as a whole, please visit 22/7 Wiki.''

22/7 (ナナブンノニジュウニ; Nanabun no Nijyuuni) is digital seiyu idol group, formed by a collaboration of producer Akimoto Yasushi (creator and producer of AKB48) with Aniplex and Sony Music Records. The group blends elements of anime with real-life idols. Through this the group participates in a variety of multimedia content including voice-acting, anime, virtual youtubers, and music. The original group started with 8 members and later added 3 so-called "Hidden Gems" members.

In late 2019, the seiyuu for the Nicole Saito character was replaced. In 2021, 3 of the original 8 founding members and 1 "Hidden Gems" member graduated with 1 "Hidden Gems" member being fired.

On September 20, 2021, it was announced that the group would be holding an audition to recruit new members. By the end of 2021, only 4 of the original 8 seiyuu were left and only 6 of the original 11.

Trivia

 * The group was originally supposed to feature 8 characters but was expanded to 11 shortly before the group debuted. Due to this, early activities of the group only included the eight characters that were voiced. The 11 member character line-up fully debuted in their fourth single. The Seiyuu who didn't have characters that were voiced still participated in activities alongside the group and released the same promotional material as the other members and are considered to have participated in the first three releases.
 * The group was originally formed with 12 members, however the twelfth member did not end up debuting with the group for reasons unknown.
