They are the first DSP Media's boy group in a long while. On May 1st, DSP Media revealed that A-JAX will be the first Korean idol
group to debut within Korea and Japan simultaneously, and will follow
in the footsteps of sunbae group, SS501. A-JAX is the official groups' name, in reference to the mythological Greek hero
that helped bring victory to the Greeks during the Trojan War. It is
composed of seven members including Hyeongkon, Jaehyung, Yunyoung,
Hyojun, Sungmin, Seungjin and Seungyub. They made the first appearance
on TV as a group on MBC Music's Making The Star - DSP Boyz in April 24, 2012. The group made its official debut in South Korea on June 1, with the single One 4 U.

Japanese media showed great interest in A-JAX since they introduced them as KARA's younger brother.

DSP Media's new
idol boy group debuted as the opening act for KARA's Saitama
concert tour in front of 32,000 crowds on May 26 and May 27.

Several Japanese media such as Sankei Sports, Nikkan Sports, Sports
Nippon, Kyodo Report and other local media covered A-JAX's debut stage.
