The Maroo Entertainment announced that "GHOST9
will make its debut on the rooftop of the 63 Building for the first time in
Korea. We recently completed pre-recording successfully in accordance with
safety rules, and the footage will be released for the first time at Mnet's
'GHOST9 DEBUT SHOWCASE [DOOR]' at 9 p.m. on September 23rd."
This marks the first time for a K-pop artist to
debut at the 63 Building, a landmark in Korea.
In addition, the group's debut fever has been turned
up by massive debut promotions, including a solo showcase on Mnet, which is
unusual for a rookie group.
