MAISON B GLOBAL FANS 

Maison B are a 7-member Japanese hip-hop boys group under DREAM BOY. Formed on August 18, 2022 but debuting February 15, 2023, the group is made up of former contestants of the competition show PRODUCE 101 JAPAN SEASON 2. All members of the group exited the show as rank B contestants, but were picked up by rap trainer KEN THE 390 soon after. 

​

The group's concept is to "Break" through the status of a B-ranked group and have a group with no official leaders, instead opting to have all members contribute and help with the creative process of their music, styling, social media, etc.

​

Maison B fans are called MBius, meaning Maison B, us and I - a testament to Maison B's involvement with their supporters.
