~Lucy's Pov~ 

Natsu had a serious look on his face. "The Great Power helped make the Heartfilla weapons long ago. The weapons both of your brothers use. People believe it is a weapon itself, a crystal that could grant wish but they were all wrong. The Great Power is a person. You are that person Lucy Heartfilla" Natsu soon explained as I was frozen on the spot. My eyes had widened greatly. Me? The Great Power? This wasn't possible. "It was once lost after Anna Heartfilla died long ago but when Jude Ashley was hired to use the last of Anna's blood to make two twin boys.....well nature took it's chance and made you" Natsu then added.

With how serious his face was. With how serious his voice was. I was starting to believe in it. "No one knew it was you but us. The enemy believes you are just a key to get it. Lucky for us that is. They do know the Heartfilla bond, what can still be deadly to us" Natsu then sighed as I looked down at the table. I was just trying to let it all set in. "The reason Jude Ashley never let you train. The reason he came to my father right away and informed me and him. The reason you weren't allowed out....was to protect you" Natsu soon spoke.

Father. He knew. "The bond your brothers have with you is because you carry The Great Power. It makes them want to protect you all the time and so on. They can use that" Natsu spoke as I moved my eyes to look at him. His eyes were now closed. The reason they wanted to protect me so much. The reason we all share a great bond. Was because I was the source of power. I was trying to understand all this. "The power you hold could most likely destroy all life as we know it" Natsu then opened his eyes looking at me.

"Now what? Am I stuck here?" I soon asked as Natsu nodded. My hands turned into fists. Natsu then got up. "I can't let them get their hands on you or let the Hunters have a hold of you as well" Natsu soon added as I then stood up, my hands slamming onto the table. "Not happening" I snapped getting him to raise an eyebrow toward me. I wasn't going to stay hidden away. I couldn't. My brother was still out there in trouble and my other brother would go on a war rampage. "I am going to help my brothers" I spoke as Natsu smirked.

"How do you plan on doing that?" he asked moving toward me. I stood my ground. As much as I hated the thought, he was right. I couldn't help out much. "By learning how to use this troublesome power, by learning to fight. They are the only family I have left so I am going to help them" I answered right away not really thinking about my words at first. That wasn't very helpful for me. Natsu was laughing as soon he was looking at me with a huge smirk on his face. "I like it, you got guts" he spoke.

"How about a deal?" he soon asked as I crossed my arms as he looked really cocky. I also some fire in his eyes. He was excited along with planning something. "I will do anything you want, I will become your personal Demon hand. Meaning you can join us fighting, can see your brothers, help them and learn how to control that power" Natsu soon spoke about his offer what sounded a little too good to be true. There had to of been a big price for all this. A personal Demon? I would have to ask what that mostly meant.

"In return you let me drink your blood when I need or want it" Natsu then spoke as I nearly shouted 'eh' in surprise. "I thought you were a Demon?" I asked as he only laughed saying he forgot I was new to his world. He soon explained even Demons could even drink blood like vampires if they ever needed a boost of power or if they were low on it. He soon informed me as a female Heartfilla it meant my blood was special along with holding The Great Power inside of me. 

My blood was able to turn any other race but Human into different forms to fight, heal no matter what happened to them, make them no longer hungry for lifetimes but my blood would be wanted by many. "What did you mean by personal Demon?" I soon asked as Nastu leaned on the table next to us. All he had was that cocky smirk on his face. Wouldn't lie made him hot and if Laxus ever found out I thought that....we both would be dead. "Means I am to forever protect you, server your commands, teach you anything you wish, means if you wanted in a click of a finger I would be your lover and lastly I would do anything for you" Natsu then explained.

My face heated up at the lover part. If Laxus or Sting heard this deal they would freak out. They would've killed Natsu within a blink of an eye. "Oh yeah, also means we are stuck with each other until the day we die" Natsu soon added which made me think even more. I got many plus sides yes but giving him my blood whenever he wanted or needed it. I wasn't sure if it was a good idea but I knew if I didn't agree to it....he would just lock me up in a room for the rest of my life. I took a deep breath.

"Fine, we have a deal" I spoke shocking him right away as he was saying that most needed time to think about deals like this. He soon offered me his hand saying he would make the pack now. It was basically an oath. I took his hand, as he started. "I Etherious Natsu Dragneel, swear my life, my breath, emotions, soul and body to Lucy Heartfilla" Natsu spoke as a red magic seal showed up under both our feet. I looked at it for a second before looking toward Natsu. My body was starting to feel all hot. 

"I will listen to her commands, her dreams and wishes. Even if it was for me to kill myself. She will become mine and I shall become her's. I will protect her from anything, no matter the cost of it" Natsu spoke as markings were showing around my wrist as if it was a bracelet. I saw it showing on Natsu's as well. He soon moved onto one knee, still holding my hand. "Only she may have me, only will my eyes be on her" Natsu spoke before kissing my hand. My face heated up as he did as the markings on our wrist turned red.

Soon the seal under us vanished as Natsu got on his feet. "So shall we start our lessons?" he asked as I knew this wasn't going to be easy. Everything that has happened. I had to fight back. I had to help my brothers before they get killed. "Lets" I replied as Natsu took me out the room, leading me by still holding my hand. He wasn't helping my blushing face.
