Marked

"Oh no!" Sylvia exclaimed, before making a quick hand seal. 

A lightning seal appeared that she sent towards the black mass that was shooting towards Grey. 

The seal expanded to cover it completely, but a single dot from the black mass managed to pass through the lightning seal before shooting straight to Grey's shoulder. 

Grey and Void, who was on his shoulder, vanished before the black dot managed to get to him, appearing a few meters away, but their expressions changed when the dot appeared in front of them at the same time. 

They all watched helplessly as the black dot touched Grey on his shoulder. 

Grey was a little taken aback when he didn't feel anything after it touched him, and couldn't help but do a double-take at Sylvia, giving her a questioning look. 

"Take off your shirt," Sylvia ordered while walking closer to him. 

Grey did as instructed, and on the upper left of his shoulder was a small black skull tattoo.
