The new idol group was previously known as Sakurai’s new project under the temporary name book house girl. Auditions for new members were held until August, and the group will now make their breakout debut and become active.

As they begin their activities, Maison book girl also plans to simultaneously unveil a fashion brand. Launching their own artist good creations, the group put out high quality, well-designed items for sale.
