File 12: A New Case

-London-

It was not the church that was the first to know of the incident from last night. A group of men and women were examining the corpse of the female exorcist and devil found dead shortly after sunrise. The devil was found dead with numerous slash wounds made by a short blade, presumable the size of a knife based on autopsy. That is not what caught their attention though.

What caught these people's attention is the corpse of the female exorcist, specifically on how she was killed. Like with the stray devil they presumed was a target being hunted by the exorcist, she was killed by a small bladed weapon. But what alarmed them is the familiar condition of her corpse; crudely dissected with surgical precision and missing several organs.

While the devil was cut in a more random way and its heart is missing, the woman still has her heart but some of her other organs in her lower body is missing and the cut that killed her is more surgical, made so that the perpetrator can take out the victim's organ in a relatively good condition.

A certain burly man with short gray hair and thin facial hair wearing a black suit with a tie frowns as he examines the scene of the crime, particularly the female exorcist's corpse. As a doctor, he would be the one who performed the autopsy but he knew he won't need one just with a glance.

"Just like back then."

He mumbled, remembering a certain unfinished case from more than a century ago. The White Chapel Murder case that was the start of a legendary serial murder that remains unsolved to this day. Back then he was not actively involved in cases yet but he had been there and witnessed the murder scene and even did an autopsy on one of the victims as a medical specialist called in by the Scotland Yard.

Just by the report from his men he already had the suspicion of who the perpetrator is. But now that he had seen the corpse with his own eyes, he is now sure he knew who killed the exorcist. It was one of the autopsy he would never forget and even without extensive autopsy he would recognize this method of murder by heart.

"Out of the way heretics!"

A voice called out. The man frowns and turned to the source of the voice. A group of two men and a woman dressed in robe and priestly clothing came, pushing his people out of the way. The doctor sighs. The exorcists have arrived and two of them are new faces. It was the man he did not recognize that had shouted at his subordinate. The man leading them is someone he recognized though.

"Doctor!"

The priest who walked in the center addressed him. The good doctor looked at him in the eye and greeted the church member he had the unfortunate opportunity to know.

"Exorcist Richard, what a surprise to see you here."

He spoke with a hint of sarcasm in his voice. The two exorcists flanking Richard growled at the disrespect he showed to their leader and had already reached for their weapon, eager for a fight. Richard raised his hand to tell them to stand down. The two exorcists reluctantly stay their hand.

"We have an agreement, Henry. As long as you are not involved in our matter, we will ignore your activity."

"So we have."

"So what are your men doing here?"

William questioned. The man now known as Henry stared at the exorcist for a moment. The doctor sighed. He knew that the exorcist won't let the matter go. How unfortunate. This is why he doesn't like the church; territorial and rather irritating most of the time.

He knew they will butt in soon the moment he saw that it involves a dead female exorcist. But he can't help it. He had just found something interesting, one that he recognized, so he had hoped to be able to check the bodies before the church came. Well now he is out of time. But he at least had enough to confirm his suspicion and start his own investigation.

"Just checking Richard, just checking. It's all yours now."

Henry told him. He signaled his men to pull out. One by one, his men began to file out from the crime scene. Finally it's just him and the exorcists. Giving one last nod at Richard, he walked away, a bit irritated but satisfied enough to not make an argument with the exorcist.

"Should I tell him that Jack the Ripper is back?"

Henry contemplated before shaking his head.

"Nah, I'll let them work it out by themselves. That should teach them to keep a good head on their shoulder."

Doctor Henry Jekyll walked away, knowing that the next few days will be hectic for him. He had not worked on this case back then. Now it's time to pay a visit to the Scotland Yard.


Shidou Irina had set up a morning routine. She would get up early to do some early morning jogging which she would do for an hour. Physical fitness is important for any self-respecting exorcist. After a morning jog, she would return home and relax with a morning coffee. It was around that time that her parents would wake up.

Her mother would cook breakfast once she's up and Irina would take a bath while she cooks. After that the family will have breakfast together while talking about mundane things.

Once breakfast is done, Touji would prepare for any work he had that day which depends on what he's needed for as he is also a former exorcist on top of being a pastor. Depending on what work he has, he would stay at home for a few more hours or leave immediately. Irina though would immediately leave for the church immediately.

It would've been just like any other normal day. She would depart from her home and head to the London branch HQ to train and wait until she received a mission. Sometimes she won't even get a mission for a whole day. That is because she is part of the London HQ which is the main office of the Exorcist Agency in the United Kingdom.

On average, a small church in small villages usually has at most a handful of exorcists posted while larger church in major cities would have up to fifty exorcists at a time with regional HQ possessing up to a hundred twenty exorcists. But as the main office of the Exorcist Agency in United Kingdom, the London Branch has up to three hundred exorcists that could easily cover the whole city. With such a number, handling work all over London is not difficult, especially since they're not the only organization fighting the supernatural.

Working as an exorcist for the Protestant sect in London is not difficult. It is, in fact, much more comfortable and peaceful compared to mainland Europe or the Vatican, not to mention the Middle East. UK is relatively well-protected supernaturally speaking with a well-maintained balance of power with three major power blocks protecting the island nation in the supernatural side.

The church is obviously one of them while the other two factions are the Pendragon family and the Golden Dawn. The Pendragon family set up their base in Cornwall and while they are not many in number, they have quality fighters and weapons passed down from the time of the Round Table. The other faction is Golden Dawn, a mage's association. All of them are powerful factions and relatively known. With the presence of those three factions, the British isle saw one of the lowest rate of supernatural-related problems in Europe.

Though Irina would find that it is not an ordinary morning today.

When Irina entered the HQ, the first thing she noticed is people talking. That in itself is not strange, especially since UK exorcists are much more relaxed due to the relative peace in the British isle, but today she noticed that instead of talking like normal, her fellow exorcists are whispering with most having a grim expression. A bit unusual unless there is bad news and bad news around here usually involves stepping on the toe of other powerful organization or a rare ultimate-class enemy.

Irina decided to ask someone. She noticed a fellow exorcist with short brown hair dressed in white robe like her, a familiar face she had not seen in a while. Her name is Octavia Amber and she is one of the few UK exorcists Irina is close with since they are around the same age. With her is another familiar face, Brandon Remington, a male exorcist with short blonde hair wearing gray coat over a white vestment.

"Octavia, Brandon!"

"Irina, you're back!"

Octavia greeted the Japanese exorcist with a warm hug. It has been a while since they last met, a few months at least, mostly because Irina was abroad due to being called to Vatican for joint mission. Now that she's back, they can continue working together again as a team.

"I miss you guys."

Irina gave a hug to Brandon and Octavia. Despite her friendly personality, Irina doesn't have many friends among the exorcists. Well, acquaintances and work colleague perhaps but apart from Xenovia, Octavia and Brandon are the only people she could use the word 'friend' to describe. It's not really a line of work where you can make friends easily.

After Irina release the two exorcists from her tight hug, the trio went inside.

"So how was your mission with those stuffy Catholics?"

Brandon asked, arms behind his head as he walk on Irina's right side. The Japanese exorcists chuckled. Brandon had been making that jab ever since meeting several Catholic exorcists who are overly serious, though Irina honestly can't refute the statement since Vatican is full of overly serious exorcists.

"It's not that bad, nothing too hard, just hunting some vampires and B-class stray devils. We also had a run-in with an A-class stray devil. That was a hard fight but me and Xenovia managed to beat em."

"Xenovia huh? I remember her, that girl with blue hair who wields Durandal, right?"

"Yup!"

Irina then started telling her friends about her missions. There's not much to tell apart from travelling to other places to hunt stronger enemies and helping other, more secluded branch in need. With the combined power of Excalibur Mimic and Destruction, most enemies are easily defeated, even those stronger than what they usually find in UK.

Irina also managed to get in some more training from Griselda and a spar with Xenovia that again ended with her defeat once the natural holy sword user draws Durandal. Overall, it was enjoyable. Then came the part about reuniting with her brother and his spar with the Head Inquisitor. Irina can't help but want to brag that she had personally met the Head Inquisitor and witnessed her power.

"Anyway, after I finished my spar with Xenovia, we…"

"Shidou, Amber, Remington! Richard called for you three! Go meet him in his office!"

Irina was cut off when a middle aged exorcist called their name, telling them that the branch head is calling for them. Irina grumbled, not happy that her story was cut short. But duty calls and maybe the chief wanted to tell them about what happened. Irina forgot to ask since her friends asked about her mission and she was quite excited to tell them but now she remembered that something happened that caused her fellow exorcists to whisper.

The team headed for the branch head's office. Once they entered the office, they stood in front of the chief's desk. Richard Carlson is his name, a man in his early thirties who is acknowledged as the best exorcist in the London branch. He had soloed an A-class stray before and won. He wields the sacred gear Sterling Blue and was said to be close to obtaining balance breaker.

"I'm sorry for calling the three of you on such short notice, especially you Shidou since you just came back, but there have been an incident that we need you to deal with."

Richard said. He took out a paper and some photos from a drawer on his desk and presented it to the team. The trio moved closer and examined the photos. It is a gruesome picture of the corpse of a female exorcist. If the three of them have not been in the business for several years, they would've puked when seeing the finely cut up corpse.

The three of them did gasp though. They recognize the exorcist in the picture. A nice lady named Alicia Winchester. While it's not like they knew everyone in the London branch, they do interact with other exorcists and after a while some names will stick. Alicia's definitely stick. She is one of the better exorcist in their rank and a nice lady who once helped them when they were just starting. To see someone they knew was killed and left in such condition is… hard to describe.

Under the photo is an autopsy report. Brandon was the first to have a read as he is the first to recover from the shock. He read through the report quickly then hand it to any one of his companion who wanted to read it.

"So our mission is basically to hunt down the perpetrator. Simple enough."

Brandon concluded. Richard nodded.

"The perpetrator is slippery. From what we could get, Alicia was killed without being able to fight back. She was killed with a clean stab by a short bladed weapon, likely a dagger but also possibly a mutated bladed limb, we can never be sure with a stray devil. After that, as you can she, she was dissected and had several organs removed, possibly to be consumed. Be careful. We suspect this opponent to be extremely fast to be able to catch her off guard, possibly a high B-rank stray devil or even an A-rank."

When he finished speaking, all three of the exorcists had finished reading the autopsy report. All three of them nodded and Irina put the report back on the chief's desk.

"We will hunt this stray and put it down chief, you can count on us."

Irina said, now determined in order to avenge her fellow exorcist who was murdered in such a gruesome way. While this is not the first time an exorcist had died nor will it be the last, this is the first time it happened to someone Irina personally knew. She will get to the bottom of this and punish the devil for their crimes against the Lord.

"Good. Also, I'm giving Shidou the permission to use Excalibur Mimic. I have a feeling that you will need it."

Irina nodded and bowed, followed by Octavia and Brandon. The three of them then turn to leave, Irina heading to where the Excalibur Mimic is stored to retrieve it. Once the three of them left, the chief sighed. Losing one of their own is never easy. He looked at the photos and autopsy result once again, examining them to the last detail to see if he missed anything because he just can't shake the feeling that they had made a mistake in their conclusion somewhere.


After retrieving Excalibur Mimic the team of three head out in search of their target. They started by scouring the outer edges of London where stray devils tend to hide during the daylight. They found nothing. No signs of any stray devils, at least one that is alive.

The team did find the corpse of a mutilated stray devil at the East End. They called for some people to clean it up. Thanks to finding that corpse, they decided that they have found a lead, concluding that their target is in the East End and that it is territorial since it killed a competition. So they waited until it was dark so their target can come out.

The three exorcists waited on the side of the road. When night approaches, people began to return to their home. It is dusk and the sun was about to fully disappear. The three began to move again.

"So, where do you think our stray devil is right now?"

Octavia asked. They have just finished eating a pack of sandwich for dinner. Can't hunt on an empty stomach.

"Probably somewhere nearby preparing for dinner. I want to finish this quickly and get back to bed."

Brandon answered. Irina and Octavia could agree with that. While they usually work at night and are used to not getting much sleep, they could appreciate a good sleep and it is another reason why many exorcist like to do their job swiftly. Not pulling an all-nighter is a good incentive for any exorcist to work.

As night begin to settle, an interesting sight happen. Mist started to appear all around them. Since it is not something new, the exorcists doesn't think too much on it other than watching each other's back and that things had become a bit more troublesome.

Unknown to them, the moment the mist appear, a figure also appear in an alley nearby. A white haired child clad in tattered black cloak materialized out of nowhere. That in itself would be frightening to any normal passerby but if anyone knew of the child's identity then they will be running for their life immediately.

After all, the child is the legendary serial killer who terrorized London more than a century ago, Jack the Ripper.


Took more time than I had hoped. Ohh well, at least I'm finally done with this chapter. So here is File 12 which is the official beginning of the mission and where Irina will begin her fight against the Ripper. Anyway, sorry for more unimportant OC addition but since we don't know just who Irina worked with in London I need to improvise. Seriously, while DxD is interesting, it is severely lacking in the human side of the development. Sometimes I just think that Ishibumi throw in random things and make it work with his brilliance which honestly sounds more like something I do.

Anyway, since I know I will have more people complaining about OC and OC scenarios, this is an AU with focus on human side of things and since the human side is sorely lacking in DxD, I'm bringing in several movies and series in to add to the fun, colorful human life. One such example is Dr. Jekyll here. He's not the Nasuverse Jekyll but take a guess on which Jekyll he is and you will find a movie I'm planning to include into a future story arc.

Now for the revs.

King0fP0wers: Yeah. That is why I decided to use Jack in the first place. And as we see, the Exorcists came to the wrong conclusion. That will definitely cost them.

Lezaroth: I'm not the first to use pure humans but most who did simply use legendary heroes or descendants. I'm going for a more normal humans approach. As for Haruka learning Touki, why do you think Haruka and Kaya are so physically strong in their spar? And they also still have more secrets with them.

scottdragoon: No... wait, are we talking about Irina or Haruka here? I'll assume it's Haruka and say no. Haruka has no holy sword or sacred gears. His sword is a sword he himself forged with help from his teacher. It has no power by itself but it is still a good sword and has functions.
