Nega Network‘s first male group Lc9 (League of Competition #9) has made their official debut and released their ratjer violent music video for “Mama Beat” through the official LOEN Entertainment YouTube channel.

The group has certainly made their debut with a bang. Their agency had already requested a 19+ rating for their violent and bloody scenes. The video shows the members in a battle royale, a violent free for all where there are no rules. The members seem to have special powers as they throw each other over a car or take hacking from a hatchet (and walk away).

The song itself (if you can listen to the song without being distracted by the group of idols beating each other up) is a catchy electro dance song and features Gain from Brown Eyed Girls.

Watch the video below but if you get squeamish from blood, prepare yourself.
