Yuuske removed the glove from his left hand to reveal black markings and put on the top of the cross. The markings converged and traveled off of his arm and on to the cross. They took the from of letters and spelled out the words.
"Ren,
Loving brother of pure soul,
You will never be forgotten."
The darkness that had left Yuuske's arm traveled back up to his arm but the words stayed, carved into the cross. He put his glove back on and stepped back. "I think that ought to be good, don't you?"
((for sake of ease, the markings look something similar to Sasuke's curse mark when it start's to spread, only they're pure black))
