this is her last update i promise XD!
ok well the mark on her shoulder is a banish mark (not a tattoo) its the mark of the Lost Light
this mark is given to angels if they fall in love with a demon, they r banished from the city of light and the mark will always remain reminding her and any other demon angel or anything else that she was shamed by the elder angels.
She has no regret in being with Zero,Shadowcry chose her own way they chose to throw her away.
