Back in May, the boys of MBLAQ made their official debut in Japan and achieved #1 on the Oricon chart with "Your Luv." To continue their promotions in Japan, the boys appeared on the June 27th edition of Hey! Hey! Hey! Music Champ. After performing "Your Luv," the boys each introduced themselves and was introduced as a "vampire unit" because they catch (bite) the listeners heart when they listen to their song. The show also briefly talked about their free debut event in Japan where more than 45,600 people came out to attend. They also advertised their upcoming concert, "MEN IN MBLAQ" on August 20th and held a funny interview section where they showed off their acrobatic moves. Check out the segment below!
