"Dad..." A black haired man with various wounds muttered, tears streaming down his face. He had killed his own father, and was having mixed feelings about it. With all the confusion, he couldn't focus on anything except for the black mark etched into his skin.

His father had left behind the power to slay devils, and told him to defeat Tartarus and destroy END.

Rising to his feet, his hair shadowing his eyes, the ice devil slayer, Gray Full Buster clenched his teeth. "Arghhhhhh!" He screamed, releasing all the sadness in one go. Even though they defeated Tartarus, E.N.D was taken back by Zeref. His father died, no. He was already dead. Why? Why did it have to be this way? Life was so cruel.

The only thing he could think of was revenge. He would get revenge, and he was blinded by rage. But for now, the ice Mage was exhausted and in pain, and found himself unable to move. Slowly, he closed his eyes and fell into a deep slumber.

In Korea...

Everybody was having a normal day when while going home, a red haired man with bright blue eyes discovered a person in front of the school gates.

The guy was covered up in bruises and cuts, which was notable by the lack of clothing.

Curious, Shin Woo poked the unknown person. As the man moved al little, it was clear he was alive, so he decided to help him, since this was not very normal to see a teenager lying in front of a school looking like that.

The redhead carried the man on his shoulder and brought him home. His mother was on a business trip anyway, so there was no need of an excuse.

...

The black haired man moved and slowly opened his eyes. Then jolted up with wide eyes. "Tartarus!" He yelled getting up abruptly wincing in pain. "Hey, calm down dude, I found you all beat up in front of our school and brought you in. You better be thankful that I was so nice." Said the redhead.

Gray was reminded of his surroundings and looked around. Everything was so modern and full of things he didn't know about. He had also noticed the bandages all around his body and the new sets of clothes he had. He was wearing a crisp white blazer and gray pants.

The ice Mage stood up and walked to the door that looked like an exit. "Wait! That's not the right door, it's the one to the right." Shin Woo told Gray a little awkwardly.

Not turning back, the devil slayer muttered a 'thanks' and turned to the right door,leaving. Shin Woo was left confused, not exactly understanding what happened. All he knew was that this was not the last he would hear about this guy.
