"Do we really need another member in the group? I mean we have Mercury..." Emerald stated through the ear piece. "Do I have to remind you of your place again?" Cinder said sternly through the ear piece. "No you don't ma'am."

"Ha. Whipped."

"Mercury please I need no more banter...from the both of you now back to the task at hand are you in position?"

"Yes." Emerald said. She stood at the top balcony looking down at the crowd of people below her. Most of them formed a circle around the cage screaming and shaking it.

The people around her shook the balcony that looked petty unstable itself. Other people on the ground around the cage in the back pushed trying to get to the front. Other people were jumping trying to get a better look at the upcoming action. Would just be easier to look from the balcony, Emerald thought to herself although the balcony was full itself.

"Mercury." Emerald heard Cinder in her ear.

"Yah, I'm in position. I'm almost about to go in so...radio silence?"

"If that's what you need then yes. Radio silence for the both of you. Open up the fregancy if their are any problems, put it back on when you get out. Got it?"

"Yes. Ma'am."

"Sure."

With that the feed went dead in both their ear pieces. Emerald would whisper a don't fuck up down to Mercury. But she doubts he could eff up this mission, especially if he's in his element of fighting.

"Here are the rules. No weapons what so ever. You fight till one of your auras brake. If your opponent's aura breaks you do one finishing move and thats it. You kill that person after their aura brakes your disqualified."

"Got it." Mercury said to the referee. The referee walked to the center of the cage. "Today we have a show full of young blood. One the left we have returning campaign, Koios." The crowd went absolutely wild. A girl walked out probably about the same age as Mercury if not then one year younger she had a short ponytail that didn't even go past her shoulders. Her hair was raven black but the ends faded into purple. Her outfit was simple black pants and a black corset with a black cloak that had a hoody finishing it off. Her mask being black as well covering the bottom of her face. Her eyes being the most distinctive especially since it was hazel eyes against dark skin.

"On the right we have a new challenger. Mercury Black." The referee anoccented.

"Wait, Black like Marcus Black? The assassin?"

"He had a son, I never knew." The whispers carried through out the crowd. Maybe it was a bad idea to use his full name, though he wasn't shocked the people in the crowd knew who his dad was. Especially in a place like this.

"All right fighters get in position." The girl walked up to Mercury and got in her fighting position.

"One."

"So black is your favorite color. Huh?" He chuckled.

"Two."

She rolled her eyes.

"Three."

That caused him to smirk.

"FIGHT!" The referee called out then jumped back.

Mercury tried to trip her up by going for her legs by trying to sweep his under hers. Which almost got her but she flipped back and the back flipped over him. Mercury got up from his position ran at her he threw his leg at her and she put up both her arms to block it.

"So you fight mainly with your legs, umm okay." Koios randomly said to him.

"Kind of cool,Huh?

She went to punch him in the face but he grabbed her hand and simply flung her forward. But she caught herself only sliding and gently hitting the cage. "hmm." She said to herself getting a fix idea of how he fought. Mercury came at her again running full speed at her, as he did she stood her ground. As he came at her she got ready to punch him again.

He took the bait, he used his left hand to block her and then swung his right leg to hit her in the head, which she dodged. She took advantage of that and upper cut him and then kicked him in the chest. Now it was his turn to go flying across the ring when his body hit the ground he automatically slid across the floor.

"Ow." Emerald said from where she was standing on the balcony.

The second Mercury looked up she was in mid air her foot getting ready to slam down on him. "Oh. No you don't." He said before her foot could make contact with his face he grabbed her ankle. Once he had her he threw her on the opposite side of the ring. Her back hitting the chained wall.

"Damn." Was all she said as she slid down the chained wall slowly she stared to stand up but Mercury was quicker.

He was their before she could get up he punched her in the face and then kneed her in the stomach. She stumbled back a little and then Mercury tripped her up with the same move he tried in his first attack when the match started. She hit the ground and got up only to get hit again the second hit Mercury sent at her broke her aura. Mercury had won.

"FINISH HER! FINISH HER! FINISH HER!" The crowd bursted out yelling while stomping on the ground and shaking the cage. Mercury shrugged and walked over to her and picked her up by the collar and threw her up in the air. When she was half way in mid air his foot connected with her stomach and he slammed her down to the ground.

"Ughh" was all that could be heard from her. As she laid their on the ground the referee counted down from three.

"Well it looks like we have a new winner, Mercury Black."

The little cheers got lost in the sea of Boo's. "Thanks for the workout." He said turning his back to he and walking away. She was in a crouched position hold her stomach struggling to breathe. "Cocky baster..." She said as she spit out some blood on to the ground then wiped her mouth.

Mercury walked out of the ring. "My winnings?" he asked the referee. "Of course. Just go to the back the boss will meet you soon and you can collect your prize." Mercury walked to what seemed to be the back and waited. "That was a good fight my boy, mind coming back for another one. Oh my manners, I'm Joe." He said before Mercury could answer him. The man put out his hand for a good shake. He was probably in his mid forties was a little on the heavy side and with the way he was dressed you can tell he had some money. Mercury shook his hand loosely. "Sorry, I was just passing by looking for something to kill time. So no."

"Well too bad you have hell of a good fighter."

"Um, my winnings?"

"Oh yah." Joe went to a safe using a key and eye recognition.

"Night teen hundred...Twenty hundred. Uh,Twenty five-hundred." He said handing the wad to Mercury which he looked at and then skimmed the top with his thumb. He looked over and saw the girl he just fought in pain.

"Theirs more money where that came from you know, all you have to do is come back." Joe's voice snapped Mercury's attention back to him.

"Nah. I'm good." He said walking away towards the girl. "Here." He said handing the girl half of the stash. "What the catch?" She asked. "No. Catch just feeling...generous...which I never do so..." He shook the money in front of her face and the smirked. She gave him a mysterious look. "Going once...twice..." Before he could say sold she took the money from his hands. "I don't want to see you ever again."

"Wow. So ungrateful." Mercury said with a shake of his head while walking away.

"Their's something off about that boy..." Koios said under her breath as she watched him walk away.

"So, did you like watching me fight?" Mercury asked as he flung a arm over Emeralds shoulder , she harshly pushed him off of her and rolled her eyes. "No but I did enjoy the parts where she was kicking your ass." They had walked out of the underground fight club and were heading to now meet cinder. It was late into night, the sound of the crowds inside fading into a calm silence as they got further away.

"What did we learn?"

Both Emerald and Mercury jumped as they weren't expecting Cinder to just pop up. "She's a good fighter. If I trained her she could probably beat me in a fight. Keyword being probably." Emerald rolled her eyes at him for the hundredth time that day. "She's good at reading enemies and their attacks. She learned Mercury's style quick and worked on finding an advantage."

"Although it didn't help her much."

Emerald didn't even fight him and she wanted to punch him in the face.

"Very good observation you two now when we get home I want you two to rest up. We have important things to attend to in the next following days."

3 days later

"You attack my son and expect me to except your offer?"

"It wasn't an a attack it was a test. I was testing his ability to hold up in a fight." Cinder explained. The whole team sat in a office like room with was a plain gray color and only had a desk and two leather chairs. Mercury and Emerald sat in thoes chairs while Cinder stood. The man before was in his mid fifties had light brown eyes and black hair with a few grays here and there, he sighed heavily. "Charles. All I ask is for a small alliance. Your place becomes our place and we have access to your people and you have access to mine." Emerald and Mercury looked at each other and raised an eyebrow. "Also your son and daughter are exceptional fighters I hate to see their talents go to waste."

"How did you know about my daughter?" Charles asked a expression showing up on his face that Mercury read as, protective.

Cinder just simply smiled her golden eyes glowing like they usually do when she thinks she has someone on edge.

"She probably started going back to the fighting ring at night again." The guy leaning on the wall said. Which they learned had the name Jett, he was the son of Charles. He seemed about six two and was lean and wore a mussel tank top on his right arm was a tattoo, he had the same brown eyes as his dad and his black hair was parted in the middle with the left side shaved.

"Do I have to put bars on her damn window now and lock her door from the outside. Geez, She's the reason I'm getting gray hair." Mercury cleared his throat. "Oh. Sorry about that, Jett please go get your sister I would like to have a talk with her." Jett shook his head and walked out the door.

"Cinder if you may." Charles spoke after Jett walked out. "Oh of course. Mercury, Emerald." "Got it." Mercury said. The two teens got up and walked out of the room. "Now we can finally discuss this in more detail." Was all the teens heard as they left the room. They stood out side the door. Mercury ended up leaning on a wall while Emerald walked around the hallway looking at the paintings on the wall. "Look if you would stop locking me in this house, maybe just maaybe I wouldn't have to sneak out to have a life!"

"Fighting in some sleazy fight club is not having a life. You could of been killed, dad's right when he says you need to stop." Jett yelled back at the voice which the assumed was his sister. Mercury smirked at the sound of the females voice which he recognized instantly Emerald just raised a eyebrow at him.

"I didn't train all these years to be locked up in a fucking house. Grandpa didn't train me to be some dansel in distress! He thought me how hold my-"

"Enough." Jett cut her off. By now they were halfway down the steps.

"Ugh you and dad are just alike. Who told you-" she paused when she reached the bottom.

"You..."

"Welp, if it isn't the cute mistress of the night." Mercury remarked.

"Xhadow. No!" By the time Jett called out and tried to grab her Xhadow had one of her duel sword at Mercury's throat.

"The weird name you used that night was just a cover up. Huh?" Mercury went to kick her but jumped back taking the sword away from his throat. "Guess you learned from that night."

"You cocky little." She ran at him full force.

Mercury was all ready in his fighting position. He blocked the first blow of the sword with his foot.

"Dumb ass..."

The words escaping her lips as she pulled another sword from her back with quick speed stabbing it into his leg. By now Charels and Cinder came out of the room. "Xhadow stop this instant!"

"Oops" Was all she could say as she twisted the blade to the right.

"Fuckkk." Was all that can be heard as Mercury fell to the ground in pain his metal leg was completely sliced. Mercury laid on the fool in horrible pain and shock. "You...good damn...bitch." He spat in between breaths. "You better think twice before taking me out in front of people that took me months to gain respect from, you dick."

"My office. Now!" Charles voice boomed at his daughter.

"Whatever." Xhadow said walking into the room his dad just walked out of.

"And that is why I want to ally with you, Charles. Your son and daughter strength together would be unbelievable." Cinder said making her final point.

"I'm sorry but she won't be going anywhere for a while. Hate to hurt your plan."

Xhadow walked down the stairs to the garage. She was walking slowly as she didn't want to do as she was told to. She didn't knock on the door and just walked in. Mercury was at work on his leg that was propped on a table, trying his best to attach the new parts of his leg to whatever was left of the old one.

"You're dad making you apologize?" Mercury asked not even looking up at Xhadow. "Yah. But you know how I am."

"Not gonna." He said and while working. Xhadow grabbed a random chair and pulled it to the edge of table.

"Why are you still here?" He asked stopping his work.

"Cause why not?" Mercury chuckled and went back to working as Xhadow zoned out. "How did you know?" Mercury asked the question snapping her out of whatever thought she was having. "Hmm?"

"How did you know about my leg? How did you know it wasnt flesh and bone?" He asked again.

"When you hit me it was harder then other people's hits thats I have fought I thought you put all your aura into your legs but I know aura can only protect you if t's your body so i know you had to be pushing it into something."

"And that something was my legs."

"Yup, that and my grandpa had one and I used to spar with him all the time."

Mercury smiled to himself this girl was smart no wonder Cinder wanted to ally with Charles. A silence fell upon them, the only sound being the clink of metal. "Not gonna ask how I lost my legs and got these?" Mercury spoke. "My grandpa said it was rude to ask amputates how they lost their legs."

"Well he's not wrong." He spoke, Xhadow put her hand out.

"Truce?"

"What?" Mercury asked.

"Where even now. You effed me up, I effed you up. I just don't want rivalry to mess us up if we going on missions or whatever." She explained.

"If your going to worry about rivalry you should look out for Emerald. Cinder says you did a good job and she tries to fight you."

"Trust me we won't have any problems,were already good friends." She crossed her arms and smiled backed.

"Well that was quick must be some female bonding mess."

"Our just a general dislike of someone."

"Wow. I'm hurt!" Mercury said looking appalled and putting a hand on his heart. Xhadow got and started to leave the room. "Hey." Mercury called at her, she stopped in the door way and looked back. "I look forward to working with you."

"Same." Xhadow said back with a smirk as she walked out of the room.
