This weekend, rookie idol unit BiS ("Brand-new idol Society"), that gained a lot of attention for their recent 'nude' music video, announced the addition of a new girl to make the unit complete again.

As you probably noticed, the music video only featured three girls, even though we introduced them as a four-member unit. The reason is that one of the girls withdrew from the unit one month ago, turning them into an idol-trio. However, they quickly found a new and announced her official addition on July 9th.

The new girl is called Terashima Yufu, an underground idol who turned 20 on Friday. One day after her birthday she finally revealed that she would join the idol unit instead of trying to pursue a solo career. Fans of BiS and 'Yufu' were surprised about the announcement, but warmly accepted her as the new member of the talented idol unit. At the same night, she had her first concert together with the other three girls at Liquidroom, a well-known venue in Shibuya, Tokyo.

BiS has a busy schedule ahead of them, with various live performances and the release of their first official single "My Ixxx" on August 3rd, so let's wish the unit and Yufu the best of luck.
