She's my reason!

Prologue

THIRD POINT OF VIEW

"Sir Meliodas!"

Mack rolls her eyes. She focused her eyes on the opponent in front of her. Her opponent has long, blonde, spikey hair. By the way she looks, no clothes are in sight. The only thing is covering her is the darkness like tattoos.

Mack reaches back and touches the handle of her sickle. She grits her teeth and hesitates on drawing her weapon.

"Not yet," she thought to herself.

Derreirie gives Mack a smirk then spits on the ground. This act boils rage inside of Mack. If it's one thing that really gets out of her nerves, it's mischievous behavior.

"Why won't you use your powers against me. I at least want this to be entertaining before I kill you," Derreirie says.

Mack didn't answer her. She knows exactly knows what Derreirie's going to do. Besides, she was once a commandment. The commandment of everything good but changed once she and Meliodas went rogue and became a sinner along with some people (okay, only one's a person) we found.

Mack squares off with Derreirei. Mack smirks and slowly inches towards her sickle. Derreirei watches her with interest and chewed on the inside of her cheek. Mack draws the sickle and the dust on the road stirs. A fire like ribbon wraps around her arm and leaves a purple scar on her arm. Her eyes turn solid black and a black tattoo appeared on her forehead.

Mack flies in the air and dives at Derreirei. She smirked and jumped out of the way. The ground under Mack collapsed. She looked up at Derreirei with no written emotion on her face. Purple and black flames appear on the sickle.

Mack and Derreirei charge at each other, canceling each other's attacks over and over again. Meliodas and King come running in, they're eyes meet up to the battle going on over top of them. King looks terrified as Meliodas is just shocked.

"Captain, is that Mack?" King asked.

"I don't believe it." Meliodas says and puts his hands on his neck and chuckles, "I didn't think she would ever use her powers in public."

"Captain, you know who she is," King asked.

"Yup."

Derreirei looks down at Meliodas and King. Mack draws the sickle abover her head and strikes down. It makes contact on Derreirei's head and sends a blast behind the strike sends Derrierei into the ground. Derreirei's eyes widen and gasped. She quickly stood back up before Mack sends in another blast.

Mack followed after Derrierie throughout the city. Derrierie looks behind her and scuffs.

"I can't shake off this stupid b*tch," Derrierie said to herself.

Mack slowly catches up to Derrierie. She looks to her side and bites the inside of her cheek. Mack looks beside her and makes eye contact with Derrierie. She elbows Derrierie to the side and she fall and rolls 40 feet across the road until crashing into a wagon.

Derrierie gets up completely annoyed at the fact that a little child managed to lay a hand on her. She spits on the ground again and looks bored.

"You really think that you, a child can defeat someone like me?" Derrierie asks and grits her teeth.

"Oh please. I dealt with way more deadlier people than you. You're just, a slutty demon who doesn't wear clothes. I mean, come on! Children are watching!" She says and looks towards Meliodas. Meliodas just smirks at her words. King blocks the attack with his sphere. Derrierie rolls her eyes, and charges at her once again. Mack grunts, and started feeling weak from using to much of her energy. She used her powers for too long, and it was weakening her.

"Miss. Mack!" Elizabeth shouts beside the captain. King felt worried for her. More worried than he intentionally felt on being. He wanted to go up and save her. But so did the captain. He noticed how she was, since he doesn't want her to get hurt, he wanted to do something to help. The one thing that conserned him was the fact that he doesn't have all his power. But right now, he has to put that to the side and risk himself to protect her.

Derrierie goes in for an attack, Meliodas didn't have time to sort all his emosions and worries, he threw himself in front of Mack and drew his sword. She punched but it was blocked by Meliodas's sword.

"Huh?" she says and looked at her fist then back to Meliodas, "that hurt a little bit."

"Derrierie, why are you here?" Meliodas asked.

Derrierie bit the inside of her cheek and looked to the sky, "I don't know."

"Derrierie, why are you really here. The 10 commandments don't attack without a reason." Meliodas asked coldly.

"Well, I don't have a choice ya know." Derrierie says and lowers his arms. Mack stood beside Meliodas, and he still kept an arm around her protectivly. He wasn't losing her. Not today. King gritts his teeth.

"Hey! Watch where your putting those hands!"

Mack turned to Hawk. Captain of the scraps disposal. She growls and Hawk runs towards Elizabeth. Hiding behind her legs. "If you're not here to fight us. Leave." Mack says and her fists clench. Derrierie scoffs and walks leaves.

"E-Elizabeth?"

Meliodas asks looking at Elizabeth. What he saw broke his heart. He couldn't believe what he just witnessed. Zeldris kissed Elizabeth, and she...

Kisssed back.

Meliodas looked down and a shadow covered his eyes with his head hung low. Mack backs away towards King, and King puts a hand on her shoulder.

Ever since that faithful day, Meliodas, King, and Mack (And the rest of the Seven deadly sins), traveled far and wide for the rest of the ten comnandments, in hope of finally defeating them.
