2013 - 2014: Line-up changes, "Blood Type B Girl", and Blady Soul

Despite rumors of disbandment in 2012 and early 2013, Blady released a single "B형 여자 (Blood Type B Girl)" on November 18, 2013. The group returned with five members, Kangyoon being the only first generation member to return. Thus, she was promoted to leader status in the group. This comeback saw the addition of new members Coco, Tina, Yeji and Soojin.

The single release of "B형 여자 (Blood Type B Girl)" also saw a new remixed version of "미친 날 (Crazy Day)" titled "Bring Bring" with a stronger hip hop and rock flavor than its predecessor. "B형 여자 (Blood Type B Girl)" is a collaboration between renowned producer C-Luv (who has produced for Rain, MBLAQ and Kim Hyun Joong) and songwriter Stay Tuned. The song features a funky urban electronic beat and draws inspiration from the fact that all the members of Blady have blood type B.

Blady Soul is the first special unit to come from Blady, consisting of members Yeji and Soojin. The duo released a digital single, "떠나가지마 (Please Don't Leave Me)", to commemorate White Day. The song garnered attention for its smooth R&B style in contrast to Blady's normal bubblegum-pop style.
