Foreword:
Based on a few comments and pointers I had received from Tobi Tortue and personaaddict07. I've slightly improved my plot and rearranged the spaces. I do hope this will be a much better story and I am always open to honest criticism whether it be bad or good. So please enjoy reading my Fanfiction.

10 years ago…

Somehow I found myself reflecting on my past once more. Like every other night…

Today, my family had planned to go for an outing together with my sister and me. Minako was excited as always, she sat beside me at the back seat as mother and father sat at the front. It was rare for father to have some free time to spend with us.
"Ne, Okaa-san! Where are we going for dinner?"
Minako asked and peeked at mother from behind. Mother chuckled "Well, where would you like to eat? Your father's in a very good mood today."
"Ne ne, Onii-san. Where should we go?" Minako turned to me and asked.
"How about that restaurant you like so much. Uh… I forgot"
Minako puffed out her cheeks and looked at me sternly.
"How could you forget, Onii-san?"
"Alright, settle down you two. We'll eat there for dinner then, alright Minako?" Father said and gave a quick glance to Minako. She gave a loud "Yay" and sat back on her seat.
I looked out the window. We were crossing the bridge to get to the other side of the island. I looked up at the sky and saw the brightly lit moon.

"Hey, Minako. Take a look at the moon! Its so round and big!" I said and pointed out the window, causing Minako to quickly glance out."Wow! Look at it. Its so pretty, Okaa-san."
Suddenly up ahead I saw some sort of fluttering mass glide towards us.
"What the hell?"
Father shouted and quickly turned the car to a stop, my door suddenly swung open causing me to fall out. I heard Minako's scream as I hit the roadside and rolled to a stop. My head was bleeding and throbbing, all around my vision was blurry, but I tried my best to stand up.
"Okaa-san . . .? M-Minako?"
The whole bridge was alight, my eyes grew wide as I turned to the source…

No, don't look. Please…

There was a burning wreckage, I recognized the vehicle immediately. Walking clumsily to the wreckage, my vision of the burning wreckage got clearer.

Stop it. I-I don't want to see it

"Okaa-san…? Oto-san? Minako!"
I shouted wearily and realized what had happened, in the distance was the cloaked mass, it held a gleaming object and seemed to be staring at me. I was frozen with fear, mother and father didn't move and were bleeding a lot, the fire was already consuming them. But where was Minako? On the other side of the car, Minako was still inside and was unconscious. Her head was bleeding and she wasn't moving. I had to save her somehow. I turned and was about to run to her but then suddenly I felt an extreme pain. The last thing I saw was a human figure walking towards me.

Who was she?

"I'm sorry. But this is the only way. Forgive me."

What is she?

The world went dark soon after.

I woke up with a shout and found myself in the hospital, Minako was asleep on a bed next to mine. A doctor was busy checking on her status when he realized I was awake.
"Where's Okaa-san and Oto-san?" I asked wearily.
The doctor shook his head slowly.
"How's my sister?"
"She's…"
The doctor hesitated for a moment.
"She's asleep. She won't wake up for a while."
He said with a sympathetic smile. My gaze turned towards my sister, who was smiling in her sleep. Luckily she had only suffered minor injuries and burns, so it would heal quickly. I hoped she was alright, she was my only family now. I rested myself on the pillow and looked at the ceiling, slowly drifting to sleep from fatigue.
The next time I woke up, Minako was already awake and was speaking to a doctor. She turned to me with a confused look.
"Nii-chan. Where's Okaa-san and Oto-san?"
My heart sank at her question, I opened my mouth to answer when the doctor shook his head towards me. I fell silent.
"I don't know."
"Ask the doctor, he may know." I continued dryly and looked up to the doctor.
He then explained the story that our 'parents' were waiting outside. Turns out our "parents" are my father's brother and his wife and had volunteered to adopt us. Minako seemed to have went through a very serious shock during the incident and couldn't remember most of the events in her life. She only has a vague image of all the people that she had met before because of her amnesia. The doctor had warned us that to prevent Minako's condition from worsening we should play along.

10 years of lies later…

It's my first day in Genkkoukan ever since I was moved to the Port Island once more.
10 years… Has it really been that long?
I thought to myself as I continued watching the scenery outside the classroom through the window. The slow swaying of the trees, the sun seemingly hovering over the urban horizon, little sparrows flying about the morning air. A moment of calm serenity.
"Arisato…. Minato was it?" a bored voice asked, breaking the moment.
I ignored the voice and continued to watch the calm swaying of the trees.
"Arisato-san. Its time to wake up and embrace your destiny in answering the question." The voice continued, sounding displeased.
My neighbor lightly tapped me on the shoulder and broke my gaze, causing me to turn towards my grumbling teacher.
Why are we even learning the origins of magic?
 I stood up and answered it wrong as the class roared in laughter.
"Wrong, Arisato-san. May your family have peace tonight." He said in a mocking voice.
I don't have one you idiot… They…
"Oh? You have a sister in the same class?" He suddenly said as he went over the class list.
"Arisato Minako, please tell your brother the right answer."
At the other end of the classroom, Minako stood up with a gleam in her eyes.
"It was founded in the 1450's!" She answered with a smile.
"Correct." The teacher sighed and continued his lecture.
"Are you ok, Arisato-san?" my neighbor asked with a curious blue gleam in her eyes. She moved her blonde hair behind her ear as she spoke. I nodded.
"Oh. Forgive me for not introducing myself. My name is Aigis."
She had a strange smile. Almost mechanical actually. I returned her smile halfheartedly and introduced myself.
"I hope we can become good companions in the future."
She said and turned her attention back to the black board. I looked out once more with a low sigh.
What a strange girl.

Soon school was over, and the bell rang. "Don't forget to do your revision on the Oda period for tomorrow's class." The teacher said but it seemed that nobody paid attention.
"Yo, Minato! Wanna go catch some food with me at Hakagure's?" Junpei said as he patted my shoulder.
"Lighten up, Stupei." Yukari appeared with both her arms on her hip. "Minato's too tired to hang out. Isn't that right?" Yukari said with a worried expression.
"Yeah, you look kind of bummed out. You alright?" Junpei asked, taking a closer look at me.
Tch. Why won't you guys just leave me alone?I picked up my bag, shoved past Junpei and immediately walked out of class. My sister was with a group of other girls as they continued talking at the hallway. As I passed by them, I caught a glimpse of her warm smile. How gentle it was to see her smile like that everyday. It somehow gave me hope to face the passing days.
Before I realized it, I had already reached the dorm. I quickly went in the dorm. The soft "thud" of the door closing was followed by Mitsuru-sempai giving me a quick greeting. Silently, I walked towards the staircase and spotted an older man sitting on one of the couches. Probably someone in charge of the dorm.
Who cares?
Climbing the flights of stairs to my room, I shut the door and instantly fell onto my bed. There were so many things running around my head. I put on my headsets, turning the volume up to maximum and shut my eyes. Various songs echoed in my head as it's melody blocked the world out.

The next day, I walked together with Minako to school. The early morning breeze was really refreshing for the morning walk. Students were walking past us as some hurried to school and some took their own slow pace. Once a while a classmate would greet us with a smile. Minako would return the greeting, I remained unresponsive and continued looking ahead, instead.
"Ne, nii-chan. We should probably send some gifts to mom and dad at Fukushiya. I'm sure they'll be happy to receive them." Minako said with a carefree smile as she turned to me.
I silently nodded holding back the words I've wanted to say 10 years ago.
"Good idea" was all I could say.
"Lets find something nice after school then, okay? Hey, Azumi-san!" Minako shouted as she met one of her friends on the way and walked ahead of me.
I watched Minako walk up to the school guiltily. She still couldn't remember that terrible accident 10 years ago.
Was it alright to leave it at that? To act like nothing has ever happened before?

I decided to overcome my depression and start doing schoolwork. I listened to the teachers lecture and took down notes. For some reason though, Aigis seemed to be tense and looked worried throughout the whole day.
What's wrong with her?
Before I could say a word, the atmosphere in class changed suddenly. For a moment it became unnaturally quiet, and before I realized it, there were upright coffins around the class.
"What the hell…?" I gasped, stumbling off my chair in disbelief.
Aigis ignored my reaction and stood up right away, looking at me sternly.
"Stay here." She said and rushed out of the room. Her figure disappearing out the door.
Yukari and Junpei got up from their seats looking frightened and pale. "What in bloody hell is going on?" Junpei shouted with his eyes wide open.
"Should we stay or get out?" Yukari panicked for a moment, realizing I was in a shocked daze. "Minato? Hey!" Yukari roughly shook me on the shoulders, waking me up from my temporary stupor.
I looked out the window, the sky had turn to an eerie green and there were shadows of distorted creatures wandering outside. "That's impossible." I took a few steps back, trying to understand what I just saw and paused. "Aigis told us to stay." I said turning to both Junpei and Yukari.

"Are you out of your mind? Coffins, Minato! You can see them can't you?" Junpei said and pointed to a coffin behind me.
Before I could reply, there was a deafening roar from outside the building, followed by monstrous shrill screams. "You see? Now lets go!" Junpei said and pulled both Yukari's hands and mine, dragging us out of the class.
We heard a loud crash from the lower floor. There was gunfire followed by an explosion. If this was some sort of attack, we should at least arm ourselves before escaping from whatever it is that is attacking the building.
"The storeroom. We need to arm ourselves with weapons or something." I said with a determined look.
"You're right. Junpei let's go." Yukari said and all three of us ran towards the storeroom across the floor. We passed by a few more coffins as we ran pass the coffin-filled classrooms.
Just what the hell is going on?
We quickly opened the door and found all types of cleaning equipment. Junpei shrugged and went in "At least its better than nothing." He said and picked up a foldable "Wet Floor" sign.
"We'll get better equipment at the cafeteria." I said and picked up two partly rusting metal pipes. Yukari took a mop and some liquid detergents.
"Uh, Yuka-tan. We're not going to mop the school, right?" Junpei laughed but was immediately knocked in the head by the mop.
"Of course not, Stupei!"

What happened to Aigis? She hasn't returned at all.
My mind was filled with questions of the current situation.
Suddenly there was a scream, it was familiar. I recognized that scream and knew it was Minako.
"Minako!" I shouted and quickly ran out of the room, the two metal pipes hanging on my sides and a broom handle in my hands. Junpei and Yukari shouted back at me to return but I was too far to hear them by then. I followed the scream upstairs and found Minako cowering in the corner as large humanoid figures loomed over her.
"MINAKO!" I shouted and ran towards the monsters without thinking. I managed to knock the closest one down with the broomstick, which broke on impact. Twisting my body, I reached for both the pipes and smacked the other one right through the door leading into the class. My face, my clothes, they were all stained with blood, but I didn't notice as I was filled with adrenaline.
"Minako… Are you alright?" I panted and reached out my hand to her.
"N-Nii-san! I-I was so scared!" she cried and hugged me suddenly.
"No time to stop, Minako. We have to get out of here."
She nodded and picked up a metal pole that fell off the class door. We both quickly rushed down the stairs to regroup with everyone.

Suddenly we heard Yukari's scream as we climbed down the stairs. By the time we reached the lower floor something large flew right pass me and slammed into the wall.
"Heh. Had enough?" A familiar voice said. I turned to the voice and saw the school's boxing champion, Akihiko Sanada with a grin as he adjusted his black leather gloves. "You alright, Yukari?" He asked the fallen Yukari.
She nodded with a pained expression.
"Where's Junpei?" I asked and rushed over to the two.
"He's with Mitsuru, downstairs. They went to check on the people responsible for the gun fire." Akihiko said as he pulled Yukari up to stand.
"Nii-san… Look outside."
I looked out the window and saw a man walking towards the school ground dragging a bus stop sign that had traces of blood on it. A monster charged towards him but he easily knocked it aside with one heavy swing.
"Shinji?" Akihiko said as he looked out the window next to me.
The gunfire sounded much closer suddenly and we realized it's on the same floor now.
"Akihiko! We have to get to the roof!" Mitsuru shouted as she and Junpei ran towards us from the stairs on the other side. "These guys are shadow's aren't they?" Akihiko asked Mitsuru with a serious expression.
"Yes. They are." Mitsuru answered wiping her brow from the exertion.
"Aren't they supposed to-"
"RUN!"
Before Akihiko could finish Junpei ran past Akihiko towards the stairs behind me. I turned to see what he was running away from and spotted Aigis firing bullets at the monsters using her fingers.
Is she some sort of android?
"Hurry! I cannot hold them off-"
All of a sudden, a large monster emerged from the stairs and knocked her aside, causing her to fly out the window. The sound of breaking glass jingled throughout the hallway. I watched Aigis as she got thrown off the building as the monster bellowed loudly.
This can't be happening. None of this could be real! It's just a dream. But...
"Do you dare to find out?"
There was a second voice in my head, and I was sure it wasn't mine.
"Lets go!" I shouted and turned towards the stairs, holding Minako's hand tightly. The monster roared and charged towards us.

Everyone ran up the stairs except for Yukari. She stayed behind and spilt the detergent everywhere near the staircase and ran up after us. From upstairs we felt the crashing of the monster as it slipped and fell causing the whole building to shake. But we continued up the stairs away from those things.
As soon as we reached the roof and Junpei with Akihiko sealed the door shut. From the roof I saw Aigis's unmoving body.
Is she dead? I wondered and hope she was alright.
"Hey, Shinji! Up here!" Akihiko shouted to the man on the ground outside.
"Tch, what the hell did you guys get yourselves into this time, Aki?" Shinjiro retorted back to Akihiko. "We're not sure either, but how did you know we needed help?""Those things appeared in the city suddenly. But they seemed to be concentrating their movements to the school. So I decided to find out what's happening and I knew you and Mitsuru must be under heavy shit. Now stay put! You guys didn't bring your evokers right by the look of things?" Shinjiro spat to the ground and continued walking in fearlessly.
"The door!" Mitsuru shouted as the door burst open and countless monsters rushed through it.

Everyone stood their ground and started fighting against the creatures. "Junpei!" Akihiko shouted and quickly knocked away a monster that almost delivered a fatal blow to the cap-wearing teen.
"If this keeps up…" Mitsuru became worried as she expertly brought down a monster with an epee.
I couldn't keep up with the pace of the monsters movement and was suddenly attacked from behind, "DAMN IT!" I spun in time and buried one of the pipes into its chest. Stepping back, I started breathing heavily and felt tired.
Minako continued repelling the monster's attack, but it seemed that she couldn't last long. She suddenly tripped and a large wolf-like monster took the chance, jumping towards her. Immediately I rushed forwards to save her, swinging the pipe towards the monster and intercepting its tackle. The pipe broke and I threw aside the broken remains. More were pouring in from the door, wave after wave. I clenched my fist as a group of them charged towards me. There were some shouts but it was drowned in the sea of roars.
Is this the end? Can't I protect anyone?

Time seemed to be in a stand still suddenly. Literally.
"Having some problems? Need help?" A voice said. I looked around, everything was immobile, suspended in mid-air. At the corner of my eye, I spotted a man dressed casually, there were 3 masks floating beside him. He was leaning near the door with a grin.
"Name's Aso, and I'm here to help you out of this 'infestation'. How about it?" He asked as he walked towards me. I remained silent, unsure of what to do. "Come on. The clock's ticking. I can't stop time forever you know." He chuckled at his own joke and stopped halfway, looking at me. Almost as if he was reading my mind "What is it that you desire at this very moment? Escape? Some sort of savior? What?" He said with a mischievous grin. "Oh well. If you don't want my help," He turned away slowly.
"Wait!" I called out. "I-I… I want to save everyone here."
"And you don't mind the consequences of attaining such power?" He asked mysteriously, slightly turning his head to face me.
After a long pause, "No."
"Then sign this contract." He said formally and a parchment appeared before my eyes along with a pen. Without thinking I quickly signed it and it instantly materialized in his hands. He nodded and looked at me.
"Well then. You are now an honorary guest of the Dark Room." He said with a smile. "Shall we begin?"
Before I could respond, he appeared in front of me and struck his hand right through my chest. I gagged and coughed at the sudden impact. I felt his hands moving in me, but it felt more like liquid. The sensation was unexplainable.
What is he doing to me?
 Aso started muttering to himself and I felt his hard grip clenching something within me.
"I shall summon forth thou as my vessel for all eternity. Arise from the endless sea of the heart…."

"…. Thanatos"

From that day on, my life had changed. But it was a price I was willing to pay.
