The project was first announced via Twitter on August 9, 2015, with the first production presentation and song previews being released on September 4, 2015, via nico live.

[1][2] As of January 2018 the project features an anime series, a manga adaptation, a rhythm game, a stage play, multiple music CDs, and a range of related merchandise.

When the project first began the units were: Kitakore (キタコレ), THRIVE and MooNs, but on December 4, 2015, a fourth group known as KiLLER KiNG was added.

[4] It was later revealed that in addition to "dreaming time" from THRIVE, MooNs & Kitakore would also be releasing singles on November 25, 2015, "Glory Upper" and "Koiseyo Otome (恋セヨ乙女)" respectively.

[citation needed] On September 9, 2016, it was announced that from December 2016 to March 2017 there would be six consecutive releases, with at least one single from each unit.

On June 9, 2017, the album covers were revealed and the titles for the four new songs were announced; "the one& only" by THRIVE, "Blooming Festa!"

In addition to musical releases B-Project also features an anime produced by MAGES that ran during the Summer of 2016 for a total of 12 episodes, a manga written by Morino Mizu that ran for 6 chapters in late 2016 in the monthly magazine Cheese!, an ongoing web-radio series, a mobile musical game, and stage play.

So far the series has seen the following special events: Happy Summer Eastar,[16] KING of CASTE,[17] Brilliant＊Party,[18] LOVE & ART FAMILY MTG 2017,[19] DARK in the HALLOWEEEEN,[20] and WINTER of FANTASIA.

[22] The top 3 ranked characters, Kento Aizome, Goshi Kaneshiro, and Ryuji Korekuni, had limited edition life-sized body pillow covers made as a result of the voting poll.

For 2018 April Fools the official Twitter revealed a continuation of last year's Baby-Project, known as Kids-Project, which showed the characters as pre-school children.

On August 6, 2016, it was announced that in addition to the anime and manga the series had just begun development on a rhythm game app for smartphones known as B-PROJECT～Muteki＊Dangerous～ (B-PROJECT～無敵＊デンジャラス～, B-PROJECT～Muteki＊Denjarasu～).

[29] Owing to an unexpected number of users, the game was largely in maintenance for its first week so that the servers could be upgraded to handle the increased amount of activity.

The renewal eventually went live on May 20, 2019, after several days of maintenance; to celebrate the release players received a weeks worth of free 10-card pulls in the games photo feature.

[31] The first release in the series was the web-radio show, premiering on September 7, 2015, on nicovideo and known as "B-Project Radio: Gandara Broadband".

On March 19, 2017, it was announced that the series would be seeing the release of a stage play called "B-PROJECT on STAGE『OVER the WAVE!』" beginning July 28, 2017,[33] and ending on August 17, 2017.

[35] Series producer and songwriter Takanori Nishikawa also made a brief cameo in the fourth episode as fellow performer Nishiyama.

This is Tsubasa's first job, and she gets involved in various incidents and accidents as she deals with this group of young men who each have their own differing personalities.

Returning staff members include Takanori Nishikawa as producer, and Chiyomaru Shikura, who is credited for planning and original work.

The anime cast will also reprise their roles,[38] with the exception of Hisako Kanemoto, who announced in May 2018 that she would be going on hiatus to study abroad until March 2019.

[30] The third season, titled B-Project Passion*Love Call, features a returning cast and staff and is produced by Asahi Production.
