Retrace 1

'Twas one of the ordinary days at the one of the four dukes manors accompanied by a tranquil atmosphere, calm air, and warm sun rays that soothes their uneasiness and stress due to their line of work. They may be busy solving mysteries everyday but not today. For today, the head granted them a day off ,thus, the Vesalius household threw a tea party in the leadership of the head of the family, Oscar Vesalius. He had invited the Nightrays, Baskervilles, and Rainsworths in the party. They were happily sipping their teas, talked about everything but work, took some pictures, and played some pranks with each other, but mostly, it was the mischievous boy who goes by the name of Oz Vesalius, the head's nephew, who pulled out pranks to his loyal servant and friend, Gilbert Nightray then known as Gilbert Baskerville, with the help of Xerxes Blake. The two also had Oscar fell in their traps with the help of Sharon Rainsworth, the young lady in physical appearance who you should not mess with. Then the others also joined them and tricked Liam Lunettes, Eliot, and Leo and the pranks went round and round until Oz stumbled on something upon running away from Gilbert.

"Ow!" he yelped when he dropped on his stomach.

"Oz! Are you okay!?" worried, Gilbert asked. He helped his master, Oz, to stand up and checked for any injuries. "You're not hurt, are you?"

"No. But I think he is." said Oz as he pointed to the something, rather, someone who he stumbled on. Gilbert followed Oz's finger and saw an old man in tattered and blood stained clothes who lied in his stomach unconscious. The man wore a black long sleeve with red linings that appeared like a uniform. Said uniform was tore in half leaving only the lower part. Underneath, he wore a button up white shirt and a black vest over it. His pants was also tattered and stained with blood so also as his heavy duty boots.

"What happened to him?" asked Gilbert to no one in particular. He kneeled on the man's side and rolled him over to see that this man wasn't old but around Oz physical age.

"Gilbert! Are you two alright!?" Oscar asked as he run closer to them with the rest of the group.

"We're fine! Actually, we found someone injured here." he answered back as the group finally was on their side.

"Ohh~ looks like his dead." Blake said upon seeing the young lad.

"Blake...? Might want to check on him?" Sharon asked with a smile though threateningly. Blake, in response, backed away a little and chuckled sheepishly as he sweat dropped.

"Is he still breathing?" hovering over the injured boy, Alice asked out of curiosity.

"He's fine, I think though he lost too much blood from his head injury and a deep cut across his chest." said Gilbert then Leo supplied when he noticed the thing that he missed. "Looks like he's missing his left eye. You wouldn't notice it if you won't take a better look because of the dried blood that covered half of his face."

"How did he got here anyway?" Eliot asked them as he looked around. "There aren't any trails of blood or something." he said and stared at the unconscious boy.

"Maybe he was drop here by someone?" Alice guessed.

"Well, could it be he escaped the abyss?" Blake added.

"That's possible. Most of us here were like that." said Oz.

"My, my. Uncle, let's help him and bring him to the hospital." Ada said sympathizing the white haired teen's situation.

Liam, who hadn't speak for a while, then called carriages to bring them to the hospital and as soon as they came, a doctor approached them asking how he could be of help. Alice then frantically shove Blake, the clown as she dubbed him, and pulled the doctor's collar closer to her face.

"We found a dead body and we want you to help us bring him back to life!" she exclaimed while the doctor stared at her with wide eyes, surprised and at the same time shocked by the girl's outburst.

"Calm down Alice. He isn't dead. Just unconscious." Oz said as he tapped her on her shoulder and had her release the doctor. Said doctor called for assistants. They settled the young man on bed and brought him in operating room to stitch his wounds and had his head injury checked. This took some time and Liam told them to have a quick call at the HQ telling what had happened and if they knew something about the boy's uniform. After that he went off first saying he had a report to be past tomorrow which was originally lazy Blake's report. Soon, Oscar was called for a meeting that afternoon leaving only Oz, Ada, Alice, Gilbert, Vincent, Eliot, Leo, Sharon, and Blake waiting outside the room patiently. Not long after that, the doctor went out of the room and met the group of people.

"How is he?" asked Oz as he stood.

"He lost too much of blood but he is safe now. About the cut on his chest, well, it is pretty deep and almost touched his heart but we managed to stitch it to close somehow. His head injury...we couldn't say this now until he wakes up but I assume that he'll have some random memory loss then his eye, he completely lost his left eye. I'm sorry." the doctor explained.

"Poor boy..." Alice breathed.

"Well, I think that's better than having him dead." said Eliot upon crossing his arms with a huff.

"Thank God. I thought he won't survive." Ada sighed in relief.

"Well, if isn't he lucky. Thanks to me who found him and saved his life." said Oz with pride as he put his hands on his hips which the others felt like a sweat rolled down their heads.

"Anyway, do you know the patient?" the doctor asked.

"No." Gilbert replied and Vincent added. "We just found him."

"Oh, thought so. Well, it seems you are good enough to stay by his side until he wakes up. And speaking of, he'll probably wake up after a week or so."

"Thank you for your help Doctor." Blake bowed his head.

"No problem. You can see him now. Excuse me." and with that the doctor left. They then went to the room where the teen was.

The visiting hours ended soon but the group were still inside waiting for the boy to wake up though they already knew he wont. Suddenly, a nurse came in to check the patient and then she saw them and asked them to leave. They obeyed and went home but not HIM.

Oz Vessalius.

When they finally made it out, he stealthily turned around without them noticing and went to the other side of the hospital. Gilbert, being his loyal servant and had a master complex, noticed his absence and began to search for him frantically. Not long after he saw Oz's foot going in the window he presumed their patient's room. Gilbert thought that his master had made sure to left the window unlocked before they went out so he can return when no one's watching.

Gilbert couldn't leave him alone so he followed inside.

"Gilbert? What are you doing here?" Oz asked upon seeing him.

"Well, you dissappeared suddenly so I looked for you and found you here." he answered as he closed and locked the window.

"Did anyone followed you?"

"No. I'm sure they're off already. Why aren't you going home?" he asked when he was beside his master who sat on a chair.

"Nothing. I just feel like staying here and wait for him to wake up."

"You know the doctor said he won't wake up soon."

"I know. But I just got this feeling to stay here..."

Pouting, Alice plopped down her bed. She was annoyed because her manservant left her again without permission. She only noticed it when they got in the carriage and was about to jump out of it and run back to the hospital when the clown restrained her until they reached Rainsworth manor. She had no choice, so she chose to sleep.

The next morning, Alice got up early, fixed herself, and made a dash to Sharon's room. She abruptly opened the door with a loud 'bang' that startled the sleeping beauty.

"ALICE?! What are you doing here?"

"Get up Sharon. Let's go to the hospital."

"Alright. But let me get ready, have a breakfast, and we're heading off."

"Okay!" and with that, Alice run down to the dining room and waited for Blake and Sharon.

RETRACE 1 - - -

The patient stirred upon feeling the warm sun rays on his face. Slowly, he revealed a pair of silver pools. His left hand involuntarily blocked the light that burned his eyes. He blinked a few times to clear his vision. Not again. He mused when a sickly white ceiling met his eyes. The patient moved his body to sit up, he winced when he felt his head throbbed and pain in his chest. Inhaling to calm his nerves, he looked around. He saw an IV attached to his good arm and two sleeping lads. The black haired man was sleeping on the floor, back leaning on the wall while the blonde sat on a chair and peacefully resting his head on his arms that were on his bed. He then examined himself. Bandages wrapped around his chest, a gauge on his head, and...

"Oh, looks like I'm missing my left eye again..." he sighed. He then tried to recall what had happened to him but all he could were the vague images of what looks like a battle and some unimportant lost memories but he remembered his name, age, and childhood with Mana. He remembered that he is an exorcist but couldn't remember the name of an organization, people he was with, and what he was doing while he was there. When he tried to concentrate much, his head would hurt so he stopped.

"Might as well as asked them." he said. "Excuse me."

Oz felt like someone shake him and heard an unfamiliar voice. Rubbing the sleep away, he looked at the white haired boy in front of him.

"Ah. You're awake." he smiled. "Hey, Gil. Gil, wake up." he turned and shake his companion.

"What is it?" Gil asked sleepily.

"Look, he is already awake."

Upon hearing it, Gilbert stood and was surprised to see the patient up. "I thought he won't wake up soon." he said.

"Call the doctor." Oz ordered in which Gil obeyed. Just as Gil opened the door, who he saw next were Sharon, Blake, and the idiot rabbit. Giving them a good morning, Gilbert went off and call the doctor while the three made their way inside and like Gilbert, they were surprised to see the patient was up already.

"Good morning master Oz." Sharon greeted followed by Blake.

"Good morning." he replied with a smile.

"What a surprise." said Blake as he looked at the patient. "You're up already. That's quite amazing of you."

"What do you mean?" the patient asked.

"We found you yesterday and brought you here. The doctor said it will take a week or so before you wake up seeing that you have a very deep cut on your chest that almost touch your heart, a pretty bad injury and a missing eye." Oz explained while the patient stared at them in awe.

"...Uhmm...thanks for helping me."

"Hey, what's your name?" Alice asked suddenly. The patient was about to tell them his name when he heard someone spoke in his mind. "Allen. Tell them your name and that you couldn't remember anything aside from that and your childhood. I know you don't remember me even, but trust me. I'll help you remember everything later." said the voice. At first he doubt but then again maybe he should just do as what the voice had told him.

"Allen. My name is Allen." he said, disregarding his last name.

"Allen, I'm Oz Vessalius, this one is Alice Baskerville, next to her is Xerxes Blake, and Sharon Rainsworth. The guy from before is Gilbert Nightray. Nice to meet you. How are you feeling?"

"I'm fine, thanks..." said the patient, Allen. Soon, the door opened revealing Gilbert and the doctor from yesterday and just like the others except Oz, he was surprise to see him.

Brushing off the surprise, he went over the patient, checked his wounds and asked a few questions. They then learned that he is Allen, no last name and only remembered his childhood though he remembered he was an exorcist at the unknown organization, but he didn't told them that much. Upon hearing this, the group also learned that there was no way to help Allen find his home and friends or relatives if there is but wait for his memories to come back. Oz then decided to take care of him until he recovered.

The visiting hours soon ended, the group only learned a little of Allen thus, Sharon warned them in case he is an enemy but Oz told them that there was nothing to worry about because he was sure the guy is not an enemy though he admitted that he had this mysterious and an intimidating aura around him. Blake agreed on this. Oz may be carefree and calm most of the time but nothing escapes his eyes.

Allen on the other hand had a talk with the voice inside his head face to face. He learned that it was Neah Walker, his father's younger brother, the 14th Noah of Destruction. Neah had told him everything about what happened and showed him random images of people that were familiar to him. Neah said, with this Allen's lost memories will come back sooner and help him recover fast. Allen spent one whole week in the hospital before Oz, Alice, and Gilbert came and fetched him. During that one week, Allen had all his memories back, thanks to Neah showing him his past randomly and to his Noah genes that he inheritted. He decided that he will remain like this and covered his secret up.

It took quite soom time before they reached the Vessalius manor and during the ride, Allen fell fast asleep so Gilbert carried him on his back and brought him in the vacant room that he will be using for a while. Afterwards, Gilbert went downstairs and saw Oscar by the end of the staircase talking to his nephew. Oscar caught him and ushered to join the conversation.

"Let's talk outside." said Oscar and had the maid prepare some tea for them.

"Uncle, you said that your meeting the other day was about Allen?" Oz asked.

"Indeed. Well, we don't know who he really is, where did he came from, and what happened to him so we have the staffs do a background check on him using his tattered clothes." Oscar explained.

"So, did they found anything? Master Oscar?" asked Gilbert just as the maid came and served the tea then left.

"Sad to say, but no. His uniform is so tattered and they could hardly identify it."

"What are we going to do now uncle? I know he isn't a bad guy. He might as well as a victim from a hundred years ago or something like that and was sent to the abyss."

"You may be right, Oz. We all agreed that he will stay here with us and we should keep an eye on him just in case."

"Understood." both Gilbert and Oz said in unison and the three sipped their teas together at the same time.

RETRACE 1 - - -

It was already dark when Allen woke up. He sat on the bed as he yawned and rubbed the sleep away.

"Where am I?" he asked upon taking a look around the dim room. "Oh right. Oz and Gilbert came in the hospital and offered me a house to stay for the time being."

Allen swung his feet on the side and walked up to the window. He shove the curtains aside and watched the scene before him.

What a beautiful place... He thought. Allen looked up and saw a bright silver full moon resting above the clear dark sky. He stared up on it for awhile when a knock was heard.

Allen turned around just as the door was opened. It was Gilbert.

"You're awake." said Gilbert as he made his way inside and offered Allen new set of clothes. "You can borrow my clothes. Please get dress, dinner is ready."

"Thank you Gilbert. I'm sorry if I am a burden to you." said Allen as he took the clothes.

"It's nothing. Get ready Allen, I'll be waiting you outside." with Allen's nod, Gilbert then went out of the room.

The dinner came and went by. They spent the night together as a family with the new addition. Alice kept on calling Allen 'old man' while Gilbert tried to shut her which in turn Alice's attention averted to him yelling that the seaweed must not talk. Oscar just laughed as Ada and Oz tried to pry them off while Allen sweat dropped. This is normal for him though.
