Original Generation
The original generation of B-Komachi was active for around ten years, starting from when Ai Hoshino debuted at twelve years old. Originally, the group had four members, including Ai, which later got increased after they become affiliated with Strawberry Productions.

Being uniquely captivating, Ai had been the center of attention and popularity the group had accumulated. This brought about tension and jealousy within the group and even alleged favoritism at the agency level. Nevertheless, every involved party was aware of Ai's importance and indispensability and Ai would soon become the unchanging ace and center of B-Komachi.

At the summit of their popularity, Ai was murdered on her birthday and the day of their confirmed Tokyo Dome performance. This caused a sudden disruption to the group and its agency as their president, Ichigo Saitou, disappeared from the industry entirely. Two years later, the original B-Komachi disbanded and it also marked the deactivation of Strawberry Productions's idol department.

Current Generation
The current generation started as Ai Hoshino's daughter, Ruby Hoshino, joined Strawberry Productions to become an idol, officially relaunching an idol group after more than a decade. As Strawberry Production look forward to add more members to the new idol group, she was joined by Kana Arima, someone that Aqua Hoshino recommends and goes at great length to get her to agree on joining. Ruby came up with the idea of taking the B-Komachi mantle and resurrected the group into a new incarnation after filming a collaboration with Pieyon. After the conclusion of the production of the reality show LoveNow, streamer Mem-Cho joined the group after being recruited by Aqua.

Through every connection channel utilized by the group, its members, and its agency, the new B-Komachi rose to significant popularity, following in the footstep of fame of its original incarnation. Their trip to Miyazaki for a music video production yielded a notable success. Ruby followed Ai's footsteps, becoming uniquely captivating, albeit with a darker atmosphere.

After Kana graduated high school, she announced her graduation from the B-Komachi, wanting to refocus on her career as an actress.

 * Besides Ai, no other members of the past incarnation have been identified in the manga.
 * However, the behind-the-scenes anime video has identified Meimei as the one with the bob cut and, therefore, the one who wears the orange dress.
 * It appeared that each member in the old generation used animal mascots to distinguish themselves with Ai using a bunny.
