"No Mercy," which is a piece with hip hop rhythm and rock guitar rift with the hint of Korean traditional music has ranked first place on G-Music K-Pop chart for five consecutive weeks and German Asian Monthly Music Chart, proving the success of B.A.P as K-Pop stars.

The "Epic Case," which competed for the title song with "No Mercy" is written by a composing team Double Side Kick, who wrote SISTAR's "Loving U," MBLAQ "War," Eru "I Hate You," and  Baek Ji Young "Voice."

Most of all, B.A.P will show the innocence of young boys different from the masculine charm they showed through the songs "Warrior," "Power," and "No Mercy."

Also, the re-package album is the album that Bang Yong Gook worked on last August as a solo artist for the first time.
