Hey guys, another update here! So I'll just say as a warning, weird shit ahead. And being partly Nasuverse, you've got to prepare for the weird things coming ahead...like...body fluids and shit...

NOT in that sense of course XD...sort off...yeah, I'll just start now.

Note: I do not own DxD nor Type-Moon


OC Arc I: A World Without Yuuya Kobayashi

Chapter 36: The Forbidden Desire

Unknown Location

I set my foot down, testing the floor. The building was old I can tell. It's interesting what Grigori did back then to cause this place to go out of commision. I walked in and scanned the building. It wasn't surprising that it was large, like, really large. I scanned the area and saw some bones here and there, and some tables with very, very old blood stains.

Huh...you would think they're dried up by this time of age, perhaps a Supernatural being?

As I ventured in deeper, I happen to come across a room, office it seems. Curious, I entered it and saw some broken tables and a large hole on the walls and floor, even the top had some holes as well. I looked around and saw some bookshelfs, some neat and some messed and judging from the dust, no one has touched it in a long time. I looked some more and saw some signs on the wall. It stated-

'HEAD RESEARCHER - AZAZEL'

'VICE GENERAL OF FACILITY - PROFESSOR ADAMS'

Professor Adams? Ah...the mad scientist...

Ignoring it, I saw another sign next to it. It said-

'ACTIVE - 1207 - SHUT DOWN DUE TO CRIME AGAINST ORDER - LAST ACTIVE - 1689'

Huh...how old. It's no wonder the building is in a fragile state. I huffed and left the office and ventured in deeper. I entered a room which stated 'TUBE COMPARTMENT'. Ignoring the warning sign, I entered in and saw many smashed up tubes, large as it was six meters tall. I huffed again.

This isn't what I was looking for.

I ignored the room and ventured in deeper until I saw a large hole in the floor amongst the thousands, probably endless amount of tubes. I looked down and saw what seems to be a hidden floor. Hopping down, I arrived in a more...modern floor to be specific. While it was still in ruins, this time it had metal plate floors and walls instead of rocks. I only saw two signs and two way but to my dismay, one of them was in rubbles. While I could easily blast through it, that wasn't my goal. Anyway, the sign said-

'LEFT - PROJECT GARDEN OF EDEN'

'RIGHT - ARTIFICIAL LIFE'

Ah!

Just what I was looking for. I took the right direction, ignoring the rubble. I arrived at a large door, steel it seems. I pushed it open as it creaked due to the rust and arrived at another large room. There was many tubes but this time, some of them were different, like wether it has more wires, or a fancy design. I did note one of them was missing, not destroyed but rather taken away.

I ignored that fact and looked at a specific tube far to the left side of the room. It was white in colour. Ah...I didn't even believe that it was still around...I guess my hunch was right. I went to the tube as it had a small sign, it said-

'PR0J3CT H0MUNCU1US'

?

What's with the weird writing? Never mind that. I looked around and saw it has a power source. I clicked my tongue. I guess I have to power up the entire facility...


I went outside again, leaving a trail of low leveled wisp to guide my way around. I eventually arrived back on the upper level of the abandoned facility and looked around for the generator room. This place had to have a power source...

I wandered around, this time leaving different coloured wisp to indicate wether I've gone through this area or not. After what I think around to be an hour, I saw a door leading outside. I did so and saw a pathway, but it seemed hard to see as it was covered by moss. I easily swiped my hand and unleashed a weak, but rather large and straight forward torrent of flame as it scorched the mossy pathway.

I walked as the torrent kept going, it turned left and right a bit, signifying that I had to make some turns. Along the way, I left more wisps and eventually, the torrent of flame stopped at a very large building.

I scanned to see some door but to my dismay, I didn't see any. Huffing, I stood in front of the building, still trying to find a way until-

"What...are you doing here? Master would not be happy to know that you are doing this."

"!" I went as I stepped back and dodged a blade shooting out of nowhere. Countless golden disks surrounded me with blades coming out of it, standing by to shoot out in the event I try to do something.

"Avenger, just let me kill this Mongrel and be done with it."

"No, I want to know of her goals."

"Tch..."

I turned around and saw a lady in a black stained dress sitting on the tree branch with a man standing next to her. I raised an eyebrow and said, "Avenger and Gilgamesh huh...I never knew Yuuya's Spirits are sustained in this world."

"We get to choose wether we leave or not...but usually the Grail takes us back by force." Avenger said in a calm manner. "But of course, this world's Grail is different in a sense is it not?"

I made a nod of agreement as Avenger continued, "So...again. Tell us what are you doing here?"

"To bring Yuuya back of course."

"Why?"

"I have my reasons."

"As his 'Other Self'...I suggest you stop this. He deserved his well earned rest."

"Not like this...he still has much more to do." I replied with a grin. "After all...you're not actively opposing me aren't you? If you were, you would have killed me before I could have entered this facility."

Avenger remained silent making Gilgamesh frown. I looked at him with a smirk and said, "You too, am I right Gilgy?"

"You-!"

"Gilgamesh." Avenger said as she stood up making said man growl at me. I tilt my head and said, "So? What are you going to do now?"

"..."

"Avenger..."

"I know. Master deserved his rest but..."

"You can't just help to have a selfish side to bring him back right?" I said as I spread my arms. "Why don't you help me in this Project?"

Avenger remained silent but hopped down from the tree and said, "And...how do you suppose you can do that?"

I turned around and faced the building. "First thing's first, this building."

Avenger never said anything, but she placed her hand on the building as black with red linings surrounded it. A magic crest was seen followed by it glowing red, then dispersed as the rock opened in half.

Gilgamesh sighed and made the disk dispersed as he said, "Yuuya will not be happy with this. I serve no purpose here now. I'll be with the rest." As he dispersed with his body going astral.

I grinned and said, "Glad I got your-"

"I am no part of this, I have no involvement in this."

"I'll keep my mouth zipped~"

Avenger ignored me and walked in the building with me following suite. I saw many large generators, dead of course. Avenger merely swiped her hand and unleashed many shadow like beings which attached themselves to the generator followed by morphing into it. The generator started pumping before it was vitalized with energy, in fact, it became better than the original state. Maybe enhanced with the All Worlds Evil tainted mud had a good effect on it?

I shrugged as we both made our way back to the room with the tubes in it, there Avenger said, "So...what is your plan?"

I tapped the white tube and said, "Simply put, I want to bring back Yuuya at the state he was before. An Invoker but...he wont be human. To fully synchronize with his magic circuit and his Spirits, I'll recreate him as a new being entirely. A being that is considered to be a...'magic circuit with a human body' and for that-"

"A Homunculus."

"Bingo!"

"And...then what?"

"Give him back to Eiri of course. She'll use the U.S.S's 'Fake Pieces' on him without hesitation and when he wakes up, she'll take the blame. Simple if I say so myself!"

"Fake Pieces?"

"Ah...you don't know of the U.S.S properly do you? It took me three Leaders I had to bring down to learn deeper about them. A secretive bunch they are. Anyway, the U.S.S incorporates these Pieces are rather...as stated, Fake therefore disposable. None of the U.S.S Leaders are given real ones hence their Peerage members retain their 'Original' self, like Eiri's Queen as a Vampire and stuff."

Avenger made a nod and said, "And how are you to make a Homunculus?"

"Simple!" I replied and swiped my hand as a magic crest appeared with a very large book appearing. "I happen to take Papa's grimoire with me when I left my household so I have pretty much a good idea on what to do."

"...and..."

"Ah yes...I of course need a model. I'll be using THAT [1] family's model. Despite it's mostly female, I'll just mold the body in the likeness of Yuuya."

"Before we began...why a Homunculus?"

"Well...as I stated before, I want him to be fully in sync with his powers. A Homunculus is, as again stated before, a being which is made to be magic circuits. Yuuya has devastating powers but only lacks due to his horrid circuits. If I 'upgraded' him, he'll be a monster. Plus! I need to seal his Spirits within him again, and especially YOU. You are the content of the Holy Grail last I remember. It's no wonder Yuuya survived through his ordeal...it's because he was the embodiment of the Greater Grail right? To have host THAT many Spirits..."

"..."

"I too am curious as to how Jun-san transferred YOU into Yuuya without killing Yuuya in the process. Of course...I know the answer to that."

"..."

"But let us not dwell on the amazing shall we? We've got a Homunculus to make!"


And so, Avenger properly arranged the Tubes and the room itself for the ritual. It was easy for her, mostly she made her black being things do the work for her. I made a stretch and said, "Alright, to bring back Yuuya, and as YUUYA and not some kind of other beings, I'll need everything related to him."

"Mana is simple. Just take it from me." Avenger said. I made a nod before grinning.

"Here comes the fun part..."

"?"

"I'll need his DNA in the form of hair and tears, then I'll need some Skin for added flavour and lastly..." I said as I hugged my sides and grinned in a wild manner. "His body fluids in the form of semen for the power punch!"

"You are mad."

"It's as expected for the Daughter of a Mad Magician."

Avenger ignored me and said, "And...where are you going to get that? Yuuya is gone-...no..."

"Yep!"

"...are you really going to do it?"

"Of course! She too is a girl like me so some little...touch...wouldn't harm her would it?"

"..."

"Heh...I'll be off...for the person who is exactly like Yuuya can none other than be his twin sister!"


Meanwhile...

She ran. She ran and ran. This would be the third time she ran away from the safe house, she didn't want to be with anyone right now. She doesn't even want anyone right now. She wanted her brother.

For Rindo Kobayashi, the past few days was like a storm. Her brother died, she regained her memories and Ren snapped. She now had a blank look, not talking to anyone, not even her own sister, but that didn't matter for she too didn't talk to her.

After regaining back her memories, Rindo made use of her extremely good magic circuits to run away from home. She wanted to be alone yet Strada would always find her. This time however, she used a long distance magic spell to transport herself to another area entirely.

Where she was now she didn't care.

All she wanted was her brother.

She eventually took notice of her surroundings. A forest, tranquil it was. She rested her back on a nearby tree and hugged her legs. Tears began to flow down again. How many times has she cried? She lost count. She sighed heavily until-

TWITCH!

"H-Huh?" She went, alert. She stood up and saw...something...walking towards her. It was but a rabbit. She sighed and turned around and-

"Hello Rindo-chan~"

"KYAAAAAA?!"


She groaned as her head was slightly spinning. Someone knocked her out in a flash and took her somewhere. She blinked a few more times before she noticed her surrounding. Still in the forest but much, much more in deeper. She took notice of the extremely high leveled magical barrier put up. She then saw another person standing nearby, she was sitting down and stared at her.

Rindo widens her eyes and-

"W-Walburga-san?!"

"Hey Rindo-chan~ remember Wally onee-chan?"

"W-Wha-"

"RinRin, I know you're scared of me. Or...maybe more towards angry?"

Rindo glared at Walburga and said, "Y-You! You started all this-"

"Blaming others wont bring him back." Walburga replied in a cold tone with brutal honesty. Rindo flinched as tears came out of her eyes again. She wanted to run but took notice of her body. It wasn't in binds but she couldn't move.

"W-What did you to me?!"

"A simple poison is all." Walburga replied with a grin. Rindo widens her eyes in fear as Walburga walked towards her.

"W-What do you want?!"

Walburga grinned in a wicked way as she took out a knife and several vials. She tossed the vials near Rindo's legs as the older girl sat next to Rindo. The girl took note Walburga dropped several more vials as she grinned and brought the knife closer.

"No! No no no no! Stop!" Rindo cried but-

SHICK!

"E-Eh?" Rindo went as Walburga cut but a few strands of her hair and placed it in a vial where she randomly toss it somewhere. Rindo blinked as Walburga took three vials and filled them with Rindo's tears, before again tossing them into the direction of where she threw the first vials.

Walburga took Rindo's hands as her fear began to rise again. Walburga pointed the knife at Rindo's index finger and poked a small hole in it causing Rindo to wince as Walburga filled a vial of her blood, and tossed it again. The older girl moved onto the middle finger and gently, ever gently, skinned but a tiny part of Rindo's skin finger and placed it in a vial.

Rindo sniffled as Walburga tossed the vial again. She noticed six more vials remained as Walburga grinned and said, "Now then RinRin..."

Rindo sniffled and said, "W-What do you want from me?"

"Your body fluids."

"Huh-"

CHU

"MMPPFFF?!" Rindo went and widens her eyes in shock. Walburga had pressed her lips onto Rindo's making the yonuger girl squirm and shook violently in shock but due to the poison, she couldn't do much.

Walburga grinned and departed as she rested Rindo on her back and crawled on top of her. Rindo shook her head and said, "NO! NO NO NO! LEAVE ME ALONE! ONII-CHAN! HELP ME! HELP ME HELP ME HELP ME HELP ME!"

Walburga licked her lips at the sight of the girl squirming as she unbuttoned Rindo's top. The younger girl began to screech but silenced when Walburga pressed her lips on hers again. This, the older girl groped Rindo causing the girl to widen her eyes again and squirmed more but during that moment of shock, Walburga inserted her tongue into her making Rindo widen her eyes in shock more.

"MMPPFF! MPPFFF!" Rindo went as tears flowed more as she felt Walburga's tongue invaded her mouth. It was hot and she expected her to feel weird but...why didn't it feel foreign?

Seeing her stop made Walburga grin and departed from Rindo as a thick trail of saliva was seen. "Oh? Not your first kiss I presume?" Walburga said as she saw the confused Rindo. Walburga shrugged and pressed her lips on Rindo's once more and quickly inserted her tongue on the still dazed Rindo.

It was when Walburga fully unbuttoned Rindo's shirt she snapped back to reality. "W-Wha-"

"Oh...my..." Walburga went as she saw Rindo's breast. The girl slightly droolled as Rindo squirmed again, shaking her breast in the process. Walburga groped Rindo's breasts, squeezing it slowly as Rindo sobbed again.

"Mm..." Walburga went as she pulled Rindo's bra down making the girl shout out in desperation. She begged Walburga to stop but that only rilled up the girl more. Walburga kissed Rindo once more but this time slid to her cheeks, then her neck as she gently sucked on them as-

"Uhn..."

Walburga grinned as Rindo's body slowly betrayed her and gave out a sign of a shameful pleasure. Walburga left trails of kisses and sucking as red marks were seen on Rindo's smooth skin. The girl eventually arrived at her main goal and grinned before giving a slow lick to the pink nipples.

"Iyahn..."

"That's right RinRin...give into the pleasure. You and Yuuya was always a weak one regarding lust."

Rindo bit her lip on frustration as Walburga latched her mouth to a nipple and sucked on them. Walburga grinned as she used her free hand to slid a finger under Rindo's skirt causing the girl to widen her eyes.

"NO! NOT THERE!"

Walburga skillyfully held one vial between her fingers as she poked at Rindo's womanhood but it was Walburga's turn to take a shock.

She was drenched.

"Oh? Aroused are you?" Walburga said as she lifted herself from the sucking. Rindo looked away in shame as tears began to flow. Walburga grinned and pulled Rindo's panties down and finally felt the radiating heat from Rindo's nether region.

Walburga grinned and said, "Now...let us start on the main event shall we?"

"NO- MMMPFFFF!" Rindo wanted to scream but Walburga pressed her lips on Rindo's one to silence her. Walburga grinned and slowly, ever slowly, inserted a finger into Rindo causing the girl squirm more but-

"?" Walburga went as she noticed Rindo stopped squirming and fell silent. She looked at the girl who now had a blank look but fell silent. Walburga also noticed-

"Y-You're...not a virgin?"

She moved herself and opened Rindo's slit as she peered in. There was no wall, barrier or anything. Walburga blinked and said, "Huh...I didn't expect this-

"... Aaahn~" Rindo went as her walls instantly tighten on Walburga's fingers and had a powerful orgasm. Walburga blinked as she felt warm fluids hitting face, and for quite a time too. Rindo's eyes rolled back as she experienced a powerful orgasm. Walburga sat up and blinked a bit, before licking her lips.

"You taste sweet."

"Neegh..."

Walburga scooped up the warm liquid on her face with a vial, before tossing it nearby. "We're not done yet."

"Onii-chan and I..."

Walburga halted herself as Rindo began speaking.

"Had a nice time comforting each other after our parents death...it was about a year after their death's to be specific. Ever since then...we kept doing it. We invited Ren-chan too."

"..."

"We gave into our sinful pleasure...but is it truely sinful when both parties view it as an act of comfort?"

Rindo rose up, already regaining back some of her mobility as she looked at Walburga. "I crave for the feeling of that forbidden desire. Will you grant me my release? Just as how Onii-chan and Ren-chan gave me?"

Walburga blinked a bit at Rindo. Her eyes were clouded with a powerful lust and her body gesture gave herself to Walburga willingly. The older girl smiled.

"I'll give it all to you."


Skipping forward - few hours later...

Walburga slowly opened her eyes as sunlight blasted her face. She blinked slowly and looked down. Rindo was hugging her tightly with her bare body whilst her clothes were scattered. Walburga made a small giggle and looked at her state of dress, it was ragged, ruffled and wet, so very wet.

She stayed longer than she had planned.

She came for six vials and will return with eighteen.

The girl smiled and gathered Rindo's clothes, put them on Rindo before engulfing her with water magic followed by using her Longinus to a small scale to dry her and finally covered her with a small amount of special powder, erasing her scent.

"Onii-chan...don't leave me again..."

Walburga tilt her head back as she gathered the vials, before opting a solemn look. She gently moved a string of hair from Rindo's forehead as she noticed tears coming down.

"Onii-chan..."

Walburga placed a finger on her forehead as she said, "You will not remember this encounter. You will only go home once you have at least calmed down."

Her finger glowed followed by Rindo's body gesture relaxing on her sleep. Nodding, Walburga stood up and left Rindo via magic seal.


Abandoned Grigori Research Facility/ Walburga's Base of Operation

Walburga arrived at the research facility and made her way to Avenger who she found was cleaning up the place. The dust was gone and some furniture was seen lying about. Avenger sensed Walburga and said, "You're back. Did you get the-...woah..."

Walburga ignored Avenger about her current state of dress and placed a box full of the vials she gathered as she said, "I've got the items. Now I just need tp start creating the new body model."

Avenger tilt her head and said, "What...did you do?"

"Me? I merely satisfied a girl who craved the forbidden desire of pleasure. Lust is indeed a scary yet delightful Sin."

Holy shit this was a weird chapter. I know I know, you're probably annoyed why the hell am I saying weird alot. Well to be blunt, I wrote this with my sister. My very own baby sister. She's like...what...three years younger than me.

CAN YOU BELIEVE HOW AWKWARD IT WAS?!

Well not awkward like Sibling awkward, I'm talking about writing Walburga's part. You see, she likes to say the dailogue and story aloud so I type, she reads it aloud.

CAN YOU THINK HOW WEIRD IT WAS WHEN SHE READ WALBURGA'S SECTION?!

My friends thought I had a girl with me or something -.-

Anyway, I overall like this chapter. Props to my lil Sis though, she insisted she wrote this chapter on some part. I'll end it here guys!

Also, Spirits.
