I woke up to my alarm blaring in my ear and I got up to start a new day. I looked in the mirror after I had changed my clothes. I was wearing a black corset top along with some black skinny jeans, black ankle boots that had laces on them, and my usual tattered jacket. I was also wearing my black choker that had the Celtic cross on it and I had a pair of black fishnet fingerless gloves. I took a deep breath as I put my jacket on and I looked at my lips before my eyes.

"I can't believe that happened," I whispered.

I walked out of my room and I began to walk down the hallway. I walked down the stairs and I walked into the kitchen to see my little brothers eating. I walked towards Rin and sat down beside him. He looked at me slightly shocked but I just stared at the table.

"Kaia," Yukio asked.

I looked up and I shook my head.

"What," I asked.

"Are you okay, you've been spacing out for at least ten minutes," Rin said.

I looked at them both and I took a deep breath.

"I'm fine," I said before I got up.

"Kaia," Yukio asked.

"Yes," I asked.

"How is your wound," he asked.

"I'm going to have a scar but I have many scars already," I replied before I started walking towards the door.

"Did you cut your wrists," Yukio asked.

I stopped walking and I bowed my head as I stood in front of the door.

"Yes, I did," I replied before I unlocked the door with my Cram School key.

I walked through the door and I walked towards my classroom. When I got to my classroom I saw that no one was in the room yet so I sat on top of my desk and took my coat off. I took my fingerless gloves off and I was glad that I decided to wear a corset top that day because I wouldn't be able to see my arms as well. I looked at my wrists to see the deep scars that I had from cutting myself when I needed to in Ghenna. I grabbed a pocket knife out of my boot and I opened it as I set it against my pale white skin. I moved the knife against my skin and I could feel the stinging as my blood began to reach the surface. After I pulled the knife away from my skin I lifted my wrist to my mouth and I licked the blood from my wrist. I could taste the metallic taste of my blood reach my tongue and I quickly grabbed a vial from my other boot before I let my blood go into the vial. After filling it to the top I grabbed some gauze from the top drawer of the desk and I wrapped it around my wrist to help stop the bleeding because I had made sure to use a knife that had holy water on it so my demonic healing abilities wouldn't work. I then grabbed a cork from my boot and I put it on top of the vial to keep my blood in it. I set the vial down next to me as I waited for the class to come in and I heard the door open. The students began to come in and I made sure to grab some vials out of the desk and also some corks to help keep the vials closed. They all looked at me confused and they saw the gauze on my wrist.

"What happened to your wrist," a blonde haired girl asked.

"That will be part of the lesson today. Today's lesson is about one of the most powerful demons, myself," I smirked.

I stood up from the desk and their eyes widened when they saw the marks on my upper arms. I then outstretched my arms so they could see every scar on my arms.

"As you can see all of the scars that I have there is a certain thing about me that only certain people know about," I began.

I then put my hands on my hips as I looked at them.

"My father made these marks appear on my arms and some people may think of it as a curse but I think it is actually a blessing," I continued.

They all looked like they were on the side of their seats as they listened to me.

"These marks on my arms tell that I am able to summon any demon from my mind also it is the meaning of the job I was given," I explained.

A brunette male cocked his head as he looked at me.

"I am the only demon in History that is able to see a demon when they are in disguise. I am able to see demons when other exorcists are not able to or even other demons may not be able to see them but I can see them. So my father hired me as an assassin so I can kill any demon that he or my brothers tell me to kill. I am also a ruler but I was never born a ruler until I defeated my brothers when they challenged me," I explained.

They continued to watch me as I held up the vial of my blood.

"My blood is actually a poison so when my competitors try to bite me or scratch me to make me bleed they will die in just a couple of minutes," I smirked while looking at my blood.

One of the males gasped and I pulled the gauze off of my wrist. I grabbed my pocket knife off of the desk and I cut my wrist again as I began to fill the vials with my blood.

"I will only give you my blood once because I am actually using a knife that was dipped in holy water so I can use it for my own needs. Only use my blood when you truly need it and never use it on human beings because it will only turn them into demons or otherwise known as the rot demon, Naberius. You are only to use my blood for a battle against a very powerful demon and if you try to use it on me my blood will not poison myself," I explained while filling vials for all of them.

After I filled all of the vials I put corks on all of the vials and I passed them out.

"You may smell my blood but when someone smells it you will think it will smell differently than someone else," I explained once I passed out all of the vials.

I walked back to the front and they all began to smell my blood. I sat down on the top of my desk and I looked at all of them.

"Any questions," I asked.

I saw a red head raise her hand and I gave a single nod.

"Are you and Arc Knight Ryuji Suguro together," the girl asked.

I was shocked in my mind but I was glad that I still had my emotionless expression on my face. I cleared my throat and I crossed my arms while I crossed my legs.

"Why not I tell you everything from the beginning," I said.

They all looked like little kids waiting for a fairy tale and I took a deep breath.

"Suguro and I were classmates in this exact classroom. My little brother Yukio was our teacher and I had no idea about my past. I had forgotten my past because one of my older brothers erased my mind so I wouldn't remember anything about my true self. So I was the age of six in human years when I was actually over three hundred years old but I was turned into a human. I lived on the streets for over ten years of my life and I was always able to see demons. An exorcist saved me one day but I was actually a thief so I wondered why he saved me. When I found out that he was an exorcist I knew why he did so I just left him alone. I had went to the village square where I grew up and I met Mephisto when I was eating sushi by a fountain. He offered me to come to school here so I came and I met my little brothers Rin and Yukio. I found out that Rin was a demon in my first Cram School lesson I almost left but I decided to stay. I met Ryuji later that day and we challenged each other to a challenge of shooting guns. I of course knew how to use a sword too so I was able to switch to my sword after my gun ran out of bullets. I won so I left and didn't pay any attention to him," I began.

They all looked amazed and I gave a slight chuckle before I continued.

"That next day I took the Exwire test and I passed so I was able to go on a mission to Kyoto with the rest of the Exwires of my class. I had to sit next to Ryuji on the train and I found out that we had a lot I common. After we got to Kyoto I met his mother and his mother actually thought that we were together. But then we decided to hang out in town and we got to know each other better," I smirked.

I took a deep breath as I started to have my past feelings make me feel slight sick but I kept telling the story.

"The next day it was our mission and I was the bait but after I passed out from the demon injecting something I dreamt about my past a little bit. I decided to take my younger brothers and Ryuji to my hometown after we got back and I found out that my best friend was possessed so I was devastated. We came back to True Cross and I decided to learn about my past so I asked Mephisto and he helped me get my powers back. I think the rest you should ask Suguro about since I can't say it," I ended.

They all looked at me sadly but they nodded. I saw that the class was almost over so I took a deep breath.

"No homework tonight," I smirked.

They all cheered and I chuckled. When the door burst open I looked at the door to see Rin panting. I quickly stood up and I looked at the students.

"Stay here," I commanded before I ran out of the room with Rin.

We ran down the hallway and I pushed open the door to see several demons attacking the school. But the main thing that made me shocked was that I saw my father. I quickly ran towards him and Amaimon was beside me as we looked at our father.

"Where is Mephisto," he asked in his demonic voice.

I kneeled down with my hand over my heart as I bowed my head.

"He is not here father," I replied.

My father looked at me and growled slightly but then he chuckled when he saw my younger brothers. He walked towards them but I put my hand on his shoulder. My father stopped and he looked at me with an unamused face. My younger brothers looked at me shocked because they thought that I would've gotten burned.

"Father, my younger brothers are not ready to go to Ghenna," I said.

Amaimon stood behind us and I let go of my father's shoulder. My father looked at my younger brothers but then I saw rooster running towards us with his gun at the ready.

"Suguro, stop," I yelled at him as he began to shoot.

My father made a wall made by his demonic flames in front of Amaimon, myself, and himself. When the wall of fire disappeared I was slightly ducking to cover myself but I saw that all of the bullets that the rooster had shot were ash on the ground.

"Ah, this is the man you said broke your heart," my father chuckled.

Suguro froze and he stared at me shocked.

"Father, I know you tried to kill him but I can handle my mission," I said.

My father looked at me and he smirked.

"Really, then where is the demon that you need to kill," my father asked.

"He is here at the school and I will be able to kill him but you need to leave so he does not find out that you are here," I replied.

"That is not good enough; I knew I shouldn't have let you come back. I bet you are only here to see this male again," my father said with disgust.

"No, I am doing my job. I have kept up to my vow and I will continue my job as an assassin," I said as I bowed with my hand over my heart.

"What," Suguro asked clearly shocked.

I stood up and I looked at him.

"I am a demonic assassin for my father," I said.

My father put his hand on the mark on my upper arm and I hissed as I felt a searing pain in my body.

"Kill the demon and then I will give you your role also this demon is Astaroth. I want you to kill him and Iblis," my father commanded.

I gave a single nod and my eyes turned cat like. I ran off but then I jumped into the air.

Ten Minutes Later

After I had killed the demon that I was assigned to kill and also kill my brothers I ran towards where my father was. I jumped into the air and I landed on my feet next to my father and Amaimon. I looked at Ryuji and he raised his gun at me.

"What are you," he asked with disgust.

"I knew that you would never accept me," I hissed.

I crouched down as the marks on my upper arms began to glow. The students from the classroom ran outside and they tried to run towards Suguro before he would shoot at me. I continued to glare at Suguro and he was about to pull the trigger when the students tackled him. I growled as I started to run towards them and I heard a gunshot go off. I skidded to a stop and I saw that one of the students had made Suguro shoot into the sky instead of at me.

"Senpai, you don't know why she is what she is," a red headed male said.

Suguro growled and he pushed the students off of him. We both stood up at the same time as we glared at each other.

"Senpai," a blonde haired girl yelled.

"What," Suguro growled as we continued to glare at each other.

"She told the same story as the story that you told us. Isn't this the one you looked for over ten years," the blonde girl asked.

"He never looked for me," I growled as I clenched my fists.

Suguro's eyes widened as he looked at me and I crouched down in an attacking position. I heard my father laugh as I made my flames ignite across my skin.

"Senpai, do what you said that you would," a black haired girl yelled at him.

Suguro raised his gun as he aimed it at me and I growled. My tail lashed behind me as I glared at him and he pulled the trigger. He then jumped at me and held me down as I heard a cry of pain. I looked at my father and I saw his host slowly turn into ash before I saw him disappear. I looked at Suguro and I growled.

"Get off of me," I yelled at him before I kicked him in the chest.

I grabbed the vial of my blood out of my pocket and I quickly poured the vial onto the ground. A salamander appeared and I jumped on top of it as I sat down cross legged. Suguro glared at me and I glared back.

"I made a vow and I will not break it unless I have to," I growled before I made the salamander begin to run.

I continued to make the salamander run before I was in the forest and I jumped off of it to see that Amaimon and Mephisto were already there.

"Our father was looking for you Mephisto," I said as the salamander disappeared.

Mephisto crossed his arms and nodded as he stroked his goatee.

"What are we supposed to do brother," I asked.

"We get to watch our younger brothers fight against our father," Mephisto smirked.

"And what do we do with Suguro," I asked.

"That is up to you sister," my brother said.

I gave a single nod and I counted in French to make my tattered jacket appear. I looked in the pocket of my jacket and I got two vials out.

"Here, take these," I said as I threw the vials into the air towards my brothers.

Amaimon and Mephisto both caught one as they looked at me. I put my jacket on and my tail swayed slowly behind me. I began to say words in Latin and my sword appeared. It wasn't the same sword that I had before because I asked my brother Amaimon to break it so I would get all of my powers and I made my gun appear on my belt.

"I will help our little brothers until it's time for them to fight on their own," I said.

"Thank you sister," Mephisto said.

I gave a single nod and I looked at Amaimon.

"Are you ready for a game, brother," I asked.

Amaimon grinned and we both began to run. When we got back to the school we walked into the school and I saw all of the students stare at us. I was glad that I had hidden my tail inside of my jacket and we continued to walk through the school.

"Who are they," I heard a girl asked clearly disgusted.

My ears were only slightly pointed because I wasn't in my demonic form and my teeth were only sharper in the canines but nothing else made me look demonic. We walked towards a door and I put my key into the lock. I unlocked the door and I let Amaimon enter first before I entered into Cram School. We walked through the hallways after we had closed the door and I walked towards my classroom. I walked in and I saw all of my students. They all stood up like they were concerned and their eyes widened when they saw Amaimon so they sat back down. My brother and I both sat on the main desk in the front of the room and we smirked at each other. I looked back at my students and I crossed my legs and arms.

"Students, let me introduce to you my brother. This is Amaimon the Earth king," I smirked.

The students gasped and then the door slammed open. I saw Yukio and Rin and I chuckled.

"I was wondering when you would get here," I smirked.

"What do you want," I heard the rooster ask as he walked in front of my little brother.

"My older brother needs help from our younger brothers. They are the only ones that can defeat our father," I said.

"But you have powers, why not you do it," the rooster growled.

"I have my limits and I had made a deal with my father so I rather not break that vow," I said.

"And what would that vow be," the rooster asked as he crossed his arms.

"Why not use your big fat head," I smirked.

The rooster growled and a student's eyes widened in realization. I saw Amaimon start chewing on his nails and I made my hands ignite in flames. The student quickly stood up and the rooster and I both looked at the student.

"Is this the person you talked about with us," the student asked.

"What do you mean," I asked as I looked at the rooster.

"He said that he was trying to find some girl that he made a mistake with," the student said.

I growled and the flames on my hands went up to my elbows.

"You made me fall in love with you when you already had someone," I growled.

I raised my hand and I threw a fireball at the wall right next to him. He stared at the fireball and then looked at me. He started running after Rin told him to run and I began to run after him. I continued to throw fireballs at him but he kept dodging them.

"I fucking hate you," I yelled at him.

He skidded around a corner and a fireball went through the wall. I continued to chase after him and we were running outside. I took my jacket off while I was running and I continued to throw fireballs at him. I saw my older brother Mephisto look at us as we ran past him and I threw a fireball at Suguro's arm but he dodged it so his clothes only got burned. When he stopped I felt someone grab my waist and I began to struggle.

"Let me go, bastard," I screamed.

I stomped on the person's foot and I scratched his arms but he kept holding me.

"Sister, calm down," I heard Mephisto say.

I stopped and my eyes widened. I gulped as I stopped struggling and he let go of me. I just stood there and stared at Suguro. The flames on my arms began to extinguish as I watched him and he continued to watch me as we both panted.

"Why," I muttered before I started walking off.

I knew my brother was following me but I grabbed my coat off of the ground and I brushed the soot off of it. I then put it back on and I looked at my brother.

"I need to finish this but otherwise after everything is done I am leaving," I said before I walked towards my dorm.

"I understand sister, but we do need a leader after our plan is taken care of," my brother said as he continued to walk with me.

"I will do it until our little brothers decide to take over Ghenna," I answered.

I saw my brother give a single nod and I crossed my arms.

"Our father will die even if I have to do it by myself and get killed. Brother do you remember the deal that we made before I went to Ghenna," I asked.

"Yes I remember, what about it," he asked.

"I want you to forget the promise and don't live up to it. The promise was made in vain," I told.

My brother gave a single nod before I entered the dorms.

The Next Day

I woke up as I took a deep breath and I walked to my closet. I grabbed a dark blue corset and some black skinny jeans for the day that I knew would end everything. After I laced up the back by myself by saying a simple spell I walked over to my vanity and put some makeup on. I had put on some mascara, black lipstick, and some eyeliner on. I then grabbed my black choker necklace with the Celtic cross on it and I put it around my neck before I stood up to grab my coat. I looked in my coat pocket and I saw that I had ten vials of my blood. I didn't put my coat on yet but I grabbed the pocket knife out of my combat boots and I grabbed some vials out of my desk. I had at least fifty vials on my desk and I cut my wrist as I let my blood fill all of the vials. I then put some gauze on my wrist after I filled all of the vials but then I took it back off and cut a star into both of my wrists. I then left the gauze on my desk without covering the wounds on my wrists and I grabbed my coat. I put it on and pulled my hair out of my coat before I walked over to my closet and grabbed my belt that was able to hold bullets in it. I put it through the belt loops of my pants and I put the newly filled vials into all of the places of the bullet holders on my belt and then put the ten older vials of my blood in my gun. I took a deep breath as I put the gun on my belt along with my other gun that was filled with holy water bullets and my last gun was on the back of my belt which was filled with silver bullets. I put my pocketknife back in my boot and I grabbed my sword. It was like any other human sword but I was glad that I had dipped it in holy water and the silver that the sword was made with was blessed so I had it in a black cloth case that surrounded the silver case with gold trim on it. The case was outlined with gold and on the case there was an inscription that was in a dead language. I had my sword on my back as the strap went around my torso like a shoulder bag and I pulled my hair up with a black hair tie. I looked at all of my piercings in the vanity and then I looked at my hair. I was always reminded of the rooster because of my hair but I shook my head as I got those thoughts out of my head. I walked towards the door and I unlocked it to see the hallways of Cram School. I walked down the hallway after I had closed the door and I walked towards my classroom. I saw all of my old classmates and also the students. They looked at me confused and I saw my brothers in their animal forms sitting on my desk. I gave a single nod and my brother turned back into their human forms. They both sat on top of the desk and I looked at the other people in the room.

"You are probably wondering why we are all here today. Today I will tell you the truth about why I am here," I said.

Rin and Yukio looked at me confused as they listened to me.

"The actual reason why I am here is because I will be fighting alongside my older brothers against our father. I have been planning on killing my father for quite a while and I know that the exorcists want to kill my father too," I began.

"But we will be killed too," one of the students interrupted.

"That is why I gave you the vials of my blood," I explained.

I heard my blood begin to drip to the floor and Mephisto looked at me concerned.

"Kaia did you do what I think you did," he asked.

I looked at him and I took a deep breath.

"I had to, if I didn't I wouldn't have been able to concentrate on what I am supposed to do," I said before I looked at the class.

They saw my blood on the floor and I took off my jacket. Their eyes widened as they saw my wrists but Suguro's eyes were the widest than any other person.

"Everyone here will only take care of my father's army while I actually go and kill my father by myself," I told as I walked to the back of my desk and grabbed a map out of my desk. My brothers moved off of the desk as they looked at the map and I looked at everyone.

"My father trusts me enough so he won't even see it coming, he thinks that I only came here to do an assassination but I came here really to join my older brother," I explained.

Everyone looked at the map from where they were sitting and I put the map on the chalk board. I grabbed some magnets and I hooked the map to the chalk board. I grabbed a quill from the desk and I dipped it in my blood from one of the stars. I began to write names on the map and I wrote my name at where my father would be. I turned back to the people and I took a deep breath.

"This is where everyone is positioned," I told.

Everyone nodded but Suguro crossed his arms and he looked at me. I set the quill down on the chalk tray and I put my sword over my shoulder so it rested on my back.

"My father will be coming in an hour so everyone get ready," I commanded.

All of the exorcists and students nodded before they ran out of the room except for Suguro. I looked at him with a slight glare and I put my hands on my hips. My brothers looked at me and I nodded. My brothers and I left the room but right when I was about to leave the room I felt someone grab my wrist exactly where my wound was. I looked at him and I saw that he had gloves on. I ripped my hand out of his grip and I walked down the hallway. Once everyone was outside we walked towards the forest and I was the leader. Once we got to a clearing I looked at the sky and it was starting to cloud up.

"Get ready," I commanded.

I heard people unsheathed their swords and I heard gun safety triggers go off. I grabbed my gun that had silver bullets out and I opened it up to see all of my bullets. I said a mantra and I knew that they were now blessed so I put the bullets back in the ready and I aimed it. I saw the portal appear in front of us and demons began to come at us.

"This will be the end, father," I whispered before the first gun shots went off.
