B.B.A. is a small division within the Jrs. It began with 7 members: Jun Hasegawa, Masashi Ito, Shoma Miyake, Shun Haseba, Shunsuke Takanashi, Tatsuya Ito and Tatsuya Ueda. Then for some reason the group seemed to have changed its members into:

Jun Hasegawa, Koki Tanaka, Shunta Miyagi, Yuta Fukada
and Koichi Goseki. But, at the end of 1999, the group seemed to have disappeared... or maybe new members are formed?
