Ghost9 have released a mysterious MV teaser for their comeback title track, "X-Ray". 

In the MV teaser, each of the Ghost9 members make a dramatic entrance in the night. At first, the members seem like ordinary teens. But the scene takes an eerie mood change in tones of black and white, as the Ghost9 boys reveal their true selves. 

Meanwhile, Ghost9's 6th mini album 'Arcade: V' is set for release on April 7 at 6 PM KST. The mini album signals the beginning of a new chapter in Ghost9's universe, the 'Arcade: VOW' series.
