Chapter 01
A new Journey

It have been several years after that fateful day, the day he fought for those he want to protect, a fight to change the inevitable fate of his loved one. He had shed countless blood in order to realize his wish even going against his loved one the one whom he dearly wishes to be with. He has determined to accept the conclusion of that fight, of what will happen when his ambition is realized. During that fight he have determined to accept his fate, a punishment to atone for every atrocities he had done till that day.

He didn't predict such result, forgiveness, an acceptance, and reprimand for doing what he had done. He honestly thought such an act was illogical, he had done atrocities in order to be with her and also he have determined to face the consequence not to be scolded after decide to punish himself by God whose all purpose is to deliver judgment.

After years he tries to realize his dream with her besides him, traveling together, but not all things are smooth. Sometimes there are people who still go against what he have accomplish, day by day their number continue to dwindle. Such battle also help him to grow stronger than before, meeting allies who have fought along with him, also gaining more understanding what his power truly are.

But now he was faced of great trial. All his ambition and wishes that he fought risking everything he had and sacrificing something along the way to brought into fruition are under threat. A threat that he have should been eliminated.

Come

Come to me

My Precious Contractor

The first, one and only human that will walk with me.

Such calling come again to him a nostalgic voice that summon him, the voice of One whom he had been contracted to. The voice of the One who approve and support his philosophy, even if no one will, he will be the one who approve him no matter what other say. Approve his ambition and helping him realizing it. That voice is calling him again, and he decides to respond to that call.

An unforeseeable disaster of unknown source has endangered the continued existence of what he had accomplished. After hearing the news that have informed to him, he was shocked, his plan should prevent such disaster from appearing. He has consulted with One who he had been contracted with, and he decide to investigate the apparent source of the threat. He said his decision to her, unsurprisingly she reject his decision. She questions why he needs to do so, to be once again separated from her. He explains to her his reasons and the situation. His benefactor can only send him, it's not like he want to leave her. Yes it is to for her sake; he cannot risk that ambition and result he had achieved in order to be with her become threatened, even if he has to leave her again. He planned to leave her behind again. It was something that he needs to do.

"Please understand, I have done everything up until now is for you."

He said to her, he sincerely hopes that she will be able to understand. He know such a thing would be selfish

"I know you are disappointed, but such disaster must not come to pass. For the sake of every one, I cannot overlook it."

He tried to dissuade her from preventing him. It is such a painful sight to see her face, and emotion that mixture of sadness and anger filled her. Such emotion may ignite a rage, but he cannot falter, not now.

"I promise with that we will meet again."

It was promise, a promise that he fully intended to fulfill. He has done everything up until now just to be with her, it would be paradoxical to just abandon her. But both need to understand why this separation, he is not going to leave her forever nor he is going to forfeit his life. With that word he departed, depart to new and unknown world. He still could heard her voice, a voice that utter his name, a voice that keep calling his name and saying he is idiot, even so he cannot stop here. He needs to go there, to confirm what the cause of calamity. A calamity that would ruin everything that he had achieved until now, a calamity that would endanger everyone he loved.

"It pains me to make you leave her; after all you have done for her." His benefactor said to him, noticing a semblance of sadness in his expression.

"It is alright, it is also my wish in the first place. I will see it to the end." That was his response for him

"Once again we will become one. You and I will walk the same path again."

Once again he merged with him, using his remaining power he forges a fragile path on the Rift between worlds to start his journey to a completely new world.

Abyss, Rift between worlds, it was dimensional void that consist of nothingness. Normally without protection one very existence could be wiped out. A forbidden spell named Pitfall of Eternity was once used to banish a black god to deep section of Abyss. That place not only consists of nothingness but defy any law known to universe. Such a place was where he walk right now, hoping reach his destination without trouble he continue to walk this path.

"We have arrived," a voice echoed in his mind.

"I will continue my slumber for a while, should you come to require my aid I will surely come for you."

Yet again that voice whisper to him, he couldn't help but smile at that. Presently his eyes are fixed forward through a glimpse of light. Light that came from brand new world. It is not the end; it is start of his brand new journey he noted to himself.

"I am here." He said with confidence in his mind

It was the word he uttered the moment he arrived in this world. Affirming presence of the breeze, he continues to affirming his own existence and existence surrounding him. He did it, he truly did it. He have been here, his mind still a bit left out to confirm this, yes a fact that he should accept by now. Right here, Right now he is in this place an unknown place, but there is something that he is certain.

"This is not my world." Such a word might be bizarre to utter from someone mouth, but it is the fact, a clear fact known to him. After that he started to move from initial position.

"Such a nice breeze."

It was the word he utter while taking a walk. He had gone to take a stroll to look of what kind of place is this. After a little stroll and wandering, he decides to gather information along the way. Despite the world bit different, fundamentally this world and the world from where he comes from are quite alike. History, Culture, Religion, Technology, and existence of human remain same.

He has a premonition that something great will happen in this city, and by great it could mean disastrous. He decides to stay this city for a while in order to investigate further, he also advised to enjoy a bit a resemblance if regular daily life while at it. To accomplish his objective he needs an identity and temporary settlement. One may call it Divine Providence; the fact that he an outsider from this world could just get an identity here was not something that anyone could just pull off. After solving the issue he decide the best action to blend this society here is by attending school.

Today is his first day attending school in this world. Bit nostalgia, reminiscence the first time he got into high school. A memory of his death an encounter with her flashed in his mind.

Kuoh Academy, a high school that just co-ed. He didn't know what kind of farce is this, the fact he is transferred to 2nd grade was a bit surprising to him. Right now he is confused; he didn't think his benefactor would make a mistake as he technically haven't complete his 1st grade education in his former school. For now he could only accept the situation a hope he could lessen the gap between his study.

Upon entering school ground he felt a strange presence, no there are two of them. One apparently comes from an old school building, and the other come from the school main building. He decides to investigate it later.

He had gone to faculty room to meet teacher to precede the admittance and ask where his class is located. He finally comes to the front door of where his class would be. He could a whispering sound from the other side of the door.

"Did you know there is transfer student come today?"

"Heeeh... You are lying right?"

"No, I am not. Also apparently a cute girl will come?"

"Huh, I am pretty sure it will be boys"

"Tch, talk about ruining fantasy"

"Will he become another prince charming?"

"Dunno"

"Oi, you lot keep quiet for a while, and transfer student over there come here and introduce yourself." The teacher proceeded to call him to come in.

As if receiving a signal, he steps up to enter the class. And he start to introduce himself

"My name is Yuji, Sakai Yuji. Hope we get along from now on."

"As I thought, he is a boy."

"Damn, here I thought an angel finally descend for me."

"You lot, are god damn noisy. Sakai your seat is over there, now proceed with our lesson." Apparently the teacher is in a foul mood.

Several days have passed since he arrived in this world, after making sure of the preparation and cover identity. He starts activity by joining library committee. Something that reminded him of Yoshida Kazumi, a friend of him that acknowledge him, accept him, and love him even he is less than human. He has developed fondness of book, because it was his source of information during his stay at Bal Masqué, learning coexistence that long he have sought over.

During his stay in library he often meet member of student council they apparently a bit aware of him. They seem didn't notice that they have been noticed. Acting normal was one of his traits. The source of strange feeling that he sense apparently concentrated on student council room. As he already located the source of strange presence, he decides to plan next course of action.

As he left library he stumble upon an unusual scene, a scene where a boy was chased around girl from kendo club. He recognize the boy, his name is Hyoudou Issei. Hyoudou Issei was a boy from his class; he is famous for his notoriety as member of perverted Trio that consists of Issei, Matsuda, and Motohama. He is not particularly close to Issei but he took pity of him and tries to give some helping hand.

"Come here." He called to Issei.

Issei quickly turned to him. Without wasting time he decides to pull Issei and shove him behind the door of empty classroom and shut the door closed.

"Ah, Sakai-san, have you seen Issei?" A female from his class named Katase asked as she approach him

"He might go over there." As he point where Issei might go.

"It is safe now." He called to Issei.

"Thanks." Issei replied to him

"Actually what did you do to incur their wrath?" as he questioned Issei

"Err. Actually, I was peeping at them." The boy replied with guilt heavily weighed his word.

"You shouldn't do that." It was a piece of advice. Sincere advices from his life experience, believe it or not girls are scary

The following days, Issei invite him to talk during lunch with his friend, during that time Issei and his co. pretty much talking about harem and particular woman body parts. Apparently Issei consider him as friend and comrade, which effect his reputation among student body. He knows Issei is not really a bad person; still his sheer antics and rambling about harem make him annoyed. He tried to distance himself a bit but one of the trio always manage to meet him in unexpected manner.

Despite what many may call gross or disgusting Issei have true determination and passion for his dream, something at least one can proud of. What he can see, Issei is just naïve boy who haven't really experience relationship.

He had experienced it. The fact, he had been in condition, where more than one girl showering you with affection. He didn't really think their act of kindness really special and accept their concern. Yoshida-san give him bento and attention Shana paid to him are too obvious for anyone to see that, they harbor special feeling to him. Well obvious to everyone, except himself that is. It was his friend Ike that told him that his current actions pretty much toying with the feeling of both Shana and Yoshida-san.

After that he really fell like an asshole, he also notes apparently Ike himself is in Love with Yoshida-san, what an ironic epiphany moment for Ike.

Even so, he still cannot make it clear whom he choose. He cannot hurt those people feeling, that only prolong the rivalry between them. Even after Shana confess her love to him, he pretty much dismiss it, he didn't feel he is worthy of her. He tried to apologize to them, only to make it worse.

"There's nothing wrong about how I feel about you, I don't want you to apologize for how I feel." Yoshida-san said to him, to make matter worse even Shana who he wanted to be with, heard that and chastised him later on.

The fact Issei consider harem king without further consideration makes it obvious. He is blissfully unaware of the consequence accepting affection from multiple girls will result in an entangled mess.

Honestly he hasn't met someone like him before, for all his fault Issei was good person who stand up to his friend.

After school, he felt yet another strange presence. Just what is wrong in this city, the presence he felt right now. There are two new hostile presences he decided to go to one within inner area of the city.

In an old school building, two woman known as Kuoh Academy two great ladies are about to discuss something. One of them is Rias Gremory the president of Occult Research Club, a girl who appeared in her late teen with long crimson red hair. The second one is Himejima Akeno her Vice-President she is girl with extremely long hair tied in pony tail, her outlook and mannerism give of vibe of Yamato Nadeshiko.

"Buchou, apparently you intuition is right." Said the black haired woman

"Of course, also I have set up preliminary action the only thing to do is wait for the result." The red haired woman replied with smile in her lip.

On the following day he came to school. He wondered what actually those two presences, but apparently he came to school a bit later than usual. During lunch break he once again invited to their bonding session. He looks at the trio, after observing for a bit he noticed that Issei is apparently incredibly happy while the other too bore a sour expression.

"Something happened?" He reluctantly asked them.

"Listen Sakai, Issei have betrayed us." Motohama said with a grimace in his face.

"Yes, that guy was a traitor." Matsuda said as he gave annoyed look at Issei.

"Traitor…?" He said with confused look. He wondered what is actually wrong with Issei

"Actually, I just get myself a girlfriend and they are just jealous." Hyoudou Issei said with pride.

"Congratulation" I offered to him. "I hope your relationship last forever" he genuinely happy for the guy with this development, maybe he would decrease his volume of breast and harem talk.

"What? Didn't you feel a thing Sakai? He got a girlfriend while we haven't." Motohama said, as if try to garner opinion.

"Not really. Also, I already have girlfriend" he answered to that silly question.

"Whaaaaaaaaaaat?" the trio said in Unison. Motohama and Matsuda apparently look like someone who just punched a hole through them.

He could see Issei pondering about something a bit. The lunch break end with two broken hearted boy heading to class. He is really confused right now, does the fact someone have found a person whom they loved really that bad.

After the school he could Issei calling to him and said he wants to talk about something. He said he had some business in library committee as he is the member and they should talk later. Imagine the surprised that he really wait for him to finish his activity, he is dedicated he can give respected to that, and it would be rude for him to turn his request.

He noticed the time is already over to roam around the school. He offer to talk at nearby café on the, just what Issei want to talk about is something that crossed his mind. They started to order something to drink and he asked the boy that seated across the table.

"What is something important that you want to talk about?"

"Actually, Sakai I need your advice."

"Advice, what kind advice you need from me?" He asked the boy.

The boy looks a bit hesitant.

"Please give me advice to make a successful date." The boy stated it to him.

Sakai Yuji was taken a back.

"You said you have girlfriend right? Please give me pointer on successful date." The boy pressed further.

"You know this is my first date, and I want it to be unforgettable experience for her and myself." Now he seems a bit desperate.

"Actually, I myself rarely go on a date. My girlfriend is currently in a faraway place." He replied to him.

"But, if I would say a word to you, you should just show how you treasure and protect her, show that you would be something that worthy for her, and if both truly love each other both of can do anything together." He continued to tell him.

"Thanks, Sakai" The boy thanked him. And they left the café to their own respective residence.

During his way home he thought a bit. Wondering what it would be if she went on date with Shana, shame such a thing is not possible for now.

Do you regret it?

"Not really, I have said it before that I am doing this for her and everyone in mind."

But you really want to be with her right?

"Of course that is the very reason I agree to our contract after all."

He continued to answer as he walked to his residence letting the night breeze pass through him.

Weekend had arrived, he decide to investigate further the source of hostility, shame ever since Johan left he lost most of his power to detect presence, even though he trained himself, it still difficult compared from before. He continued to wander the city to search where those hostilities came from. He continues to search but not much he gained during his time investigating it. Dusk had arrived and he wondered whether to search again or stopped for today, that's when he detected a great deal of hostility. He immediately ran to the place where those presences come from.

He had arrived on that place. He found nothing but a piece of paper, and there was something written on it.

"We grant your wish"

He wondered from place to place to search that hostile presence. At that time he felt the second hostile presence. He tried to trace that presence and stumble upon an abandoned building, not only the presence seem stronger, he also smell something. He continued to that building and found pool of blood and what would be called remnant of human body. There he met something that what you call monster, though some Guze no Tomogara apparently just as bizarre.

"fufufufu, never I thought a human will approach me directly".

"Is that your own doing?" He asked abomination in front of him.

"Of course, how do you like that? Awesome isn't it?" a replied with a disgustingly feminine sound replied to him.

"Does meaning of their life mean nothing to you?" He tries to press further.

"Well of course, they are precious food for us devil anyway?" Once again the monster who stated herself to be devil replied to him.

"Does every devil think like that?" Seizing chance to obtain information further, he continued to press on his inquiry. He really needed to know what kind enemy he is facing after all.

"I don't care. I feel stupid to hold conversation with food anyway." As she said those words she started attacking him.

Multiple balls with purple color come to him. After the contact an explosion occurred, such explosion could blast someone and tear them into pieces.

"Tch, a bit burnt well that will do." The devil said that as she looked o place where he stood.

He should be torn to pieces. That is what the devil in front of him might think. Except what she currently saw at the moment is his body still standing, unharmed. She observed that he has shielded himself. Multiple crystals with blue color appeared before him and block all projectile.

‹‹Grammatica››

The Unrestricted Spell that unique to him, he used it to create shield in front of him. It was a power that he discovered during final battle of the new world creation. An Unrestricted Spell that made different Effect by arranging the composition. Like grammar, word, and letter can be composed this spell potentially can become anything, he just haven't fully master it.

‹‹Fuzetsu››

As he chants the spell, an azure fire lit from his hand. The fire expands with incredible speed, less than 10 second later the fire completely encircle entire city and formed a dome. As the dome completed his surrounding change its color, it become the color of a room with a dimmed light. The fire itself however doesn't burn. He looks at the abomination in front of him. She stopped, frozen in place. He is a bit surprised so devils are not immune to ‹‹Fuzetsu››.

‹‹Endan›› it was Rudimentary spell of many Guze no Tomogara and Flame Hazes. Using that spell he decided to create fire ball and blast her with it. A ball of azure flame formed in his hand. Pouring Power of Existence to the fire ball in his hand, he projected image of destruction of the enemy to the flame in his hand. He increased the power of the flame and fired it to his enemy. The fire ball exploded upon contact the enemy, a sound of blast echoes upon the abandoned building. Upon having closer examination the enemy has completely defeated with just charred remains left. He decided to leave the place after dispelling ‹‹Fuzetsu›› and returning the flow of time to normal.

Weekday return, he goes to school. He saw Issei entering the School; oddly he felt unnatural presence from Issei. During the lunch, he noticed something really strange. Motohama and Matsuda apparently forgot Issei had a girlfriend, like she never existed before. He felt grimace, he didn't expect Guze no Tomogara here, just what actually wrong in this world. Last time, he met some abomination who call herself devil now someone existence apparently eaten.

He met Issei after school. He needed to inquire what actually happened to him. The lack of information of strange things that happened infuriates him. He sincerely hoped his meeting with Issei would clear up something. So he met Issei on the same café he met him before.

"I'm sorry to call you here." He tried to started conversation.

"Ah that's fine, really." The boy replied with disheartened voice. And expression of confusion and sadness painted on his face.

"Actually, I want to talk about your girlfriend." He can see the boy face brightened up a bit as he said those words.

"You… you… you remembered, you remembered her. You remembered Yuuma-chan" He said that and straggle him with a happy expression.

"Please calm down. Also what you mean I remembered her, of course I remember. Didn't you ask me for advice several days before?" He tried to calm the boy before him. The boy release his grip after that.

"I mean, I mean ….. Really, I didn't know anymore. Matsuda and Motohama forget about her. Her address, her phone number also disappeared." He said in a rather desperate tone.

"Okay, I understand. I will look into it, so for the time being can you promise me to keep this matter secret no matter what." He said to the boy with serious tone.

"I understand, Sakai. Please, I don't know that is happening anymore, but I really hope Yuuma-chan is alright. She is my first girlfriend; there is no way she would just disappear like that." He said in more desperate tone. Issei really show how much he dedicated himself to his girlfriend. He really hoped his prediction didn't come to pass.

Several days he decided to investigate around the place Issei went during his date. Several days he searched and asked other but no avail. Today he didn't really saw Issei during lunch, Motohama and Matsuda said he is in a club meeting right now. After school he finally saw that boy, Issei called to him.

"You don't have to bother with it anymore." Issei said to him. "You don't have to bother with it anymore, really." Once again he said Issei said those words to him. "I already meet her and she is doing alright."

"Is that so?" He wondered, as the look on Issei's face betrayed his word. He decided to ask again. "Are you sure? You sure look troubled."

"Actually, there is something I need to ask you." The boy tried to speak to him

"What is it?"

"I recently made a friend. The problem she sorta belongs to group of bad guy, and Gremory-san said I shouldn't go near them."

Wait, why he mentioned Gremory-san. What is the connection of Kuoh great lady on all of this? Then he remembered apparently few days ago Issei joined Occult Research Club, maybe she didn't want the reputation of her club tarnished if the member hangs out with a bad people.

"I really want to help her, I really do. There is no way someone kind like her would belong to such group I can see her tears flowing while we got separated. I really can" His expression same like when he desperately ask about his girlfriend to him. Just how many person Issei troubled with.

"I think you should be careful approaching this problem, wrong step and you could make that person and Gremory-san got into more trouble." He said to Issei.

"I understand. I also respect Gremory-san. And I don't want to bother her." He said to him. "Thanks Sakai, you are truly live saver." After that Hyoudou Issei left with eyes burning of great determination.

"Wait." He said to the boy. "Take this." He handed something that look like bookmark to the boy. Actually it is kind of tracking device, he suspected the boy would do something dangerous. As for the form, bookmark gave him a feeling of nostalgia as Margery-san often uses bookmark as communication device.

"What is this?" Hyoudou Issei asked him. "A Charm, I guess." He answered his question right away. He really hoped that nothing bad happened.

"Thank you, I'll be going then." Once again Hyoudou Issei left.

"I am sorry. I really shouldn't do that right?"

It is alright. I have told you that I approve what your desire right? Also I really think that a great fate will befall to that youngster.

"I just hope nothing bad will befall to that person. He really should have bright future ahead of him."

Should things come to worse; you shall come to his aid, won't you?

"Of course, I want to protect everyone. There is no point if I borrow you power to give him that and just abandon him."

Several hours after Issei left, he had done his job in the library committee. It is not unusual that library committee to not really have a job that need full personnel. Library of Kuoh academy itself quite organized as if there is magic that works behind it. During his idle time Sakai Yuji decided to read books. He had stumbled upon books that contain mythological history. The reason he read book because he think devil might come of same from their counterpart in the legend. After reading a several chapters about Ars Goetia, he remember that many Guze no Tomogara uses mythological name upon Appearing in his world. As he continued to read he received the signal from the item he gave to Issei. Using power of Serpent of Ritual he created item that would tell if the holder is in grave danger.

He hurried to excuse himself and immediately come to where Issei was located. He had arrived on a church, abandoned church. The location didn't give of presence what a place of worship should be; instead it gave off creepy feeling. He quickly uses ‹‹Grammatica›› to teleport himself to the inner portion of the church. He had arrived on the antechamber he saw Issei apparently shielding and holding a girl and a visage of a sadistic woman with black wing, he also notices that there are several other people dressed in black near her. He quickly uses ‹‹Grammatica›› again and created shield in front of Issei. As the shield formed, it collide with the spear of light that woman throws.

"What! Where did you come from?" said the shocked woman. "Tch, what are outside people doing!? Can't they keep away reinforcement just for a while?" She said with furious expression painted on her face.

"I didn't really expect to meet devil here." He said to that woman. He is actually unsure whether she is devil or not, if devil exist maybe another mythological being also exist. He does it to get information of what kind being she really is, though he is clear that she is monster, not in appearance but in term of action. He was pretty sure he could win even if he is surrounded.

"Are goddamn blind? Can't you tell the difference between us fallen angel and devil? That alone pretty much tell me you are stupid." She continued "The fact you didn't know the boy behind you is devil himself is pure idiocy" and she fired several spear of light again to him as she finished the sentence. He continued to use ‹‹Grammatica›› to defend against the assault that pretty much have no avail in breaking through his defense.

‹‹Fuzetsu››

Once again he used the spell that suspended the flow of causality within area. The entire city had been frozen in place. So were black coated people and a woman who call herself fallen angel. Unexpectedly a green light came from Issei, or more accurately from the gauntlet in his left hand. A light enveloped him and a girl that he held. He didn't aware of that gauntlet before, but dismissed that thought as he had something more important to take care of. He then proceeded to summon Blutsauger, a sword that have been his partner for several years.

Using ‹‹Grammatica›› and Blutsauger he quickly disarmed and knocked the humans surrounding him. After that he continued to finish off the fallen angel by decapitating her head. As his sword finished pass through her neck, her head continue to roll to the ground. He also decided to look at Issei condition. Using the power of Serpent of Ritual he closed the wound that have been afflicted to Issei. Unfortunately he didn't have ability to restore life to dead person. He cannot save the person Issei desperately cling to. Regret was the word that crossed his mind to express emotion he felt that time.

"I know there are many things you wanted to ask me, but I want you to promise to not tell anyone about me. If you have more questions, you can meet me on the roof top tomorrow." It was the message that he told him, just before Issei collapsed of exhaustion. Before he left, he had to ensure Issei safety. He check the reinforcement that the fallen angel talking about.

He is genuinely surprised that he saw the members of Occult Research Club, frozen apparently fighting some fallen angel and several men in black clothing and winning. He came to conclusion that they are the reinforcement that the fallen angel talking about. He decided to lend a hand a bit by disarming them and severing some tendon of remaining man and then he proceeded to fire some ‹‹Endan›› to the fallen angels. Azure flame emerged from his hand and fired to the remaining fallen angel.

He decided to leave the church perimeter and dispelled his ‹‹Fuzetsu››, as the flow of time and causality in the city returned to normal. Wondering what tomorrow hold he once again returned to his temporary residence. Such was an end of his day today.
