Chapter 2: New Beginnings.

- Flinn -

I just remembered why I hated parties in the Underworld so much. It's because there are little pricks like the devil noble children to make it annoying.

Shuri was acknowledged by my family as a member of my peerage. It was obvious. Her skills had improved during her stay in the human world.

On top of this, I made her the user of my Phenex Household Vessel. This boosted her powers a lot since Phenex was a Djinn of Life, much like the Vermilion Bird. Not to mention, her own Onmyoji techniques are great against Devils making her a great piece in the Rating Games.

The reason we were called here was for my nephew Milicas' fifth birthday.

I did sense things were a bit different in the underworld but didn't know what exactly.

Anyways, the party began and almost every prominent house of the Underworld had come.

"Flinn Gremory." I stopped on hearing a voice from behind me and found a familiar person calling me.

Sona Sitri stood there with my fiance, Latia.

Oh boy.

Where's Onee-chan? I need help.

But sadly, the help was not visible around me.

"Heiress Sitri, what a surprise? It's been a long time since we have met. How are you doing?" I smiled.

"Five years, probably because of how ardently you have avoided me."

"Avoid you? Whatever would give you that idea?" I asked, pretending to be surprised. I was totally avoiding her… to not make her cry or the Magical Girl menace will be after my ass.

"Today I will win." She left with just those words, leaving me confused about the context.

I looked at Latia for context. "You wouldn't happen to know what she was talking about, would you?"

She looked at me, slightly surprised. "You don't know? There is a contest between the youth of the seventy two pillars on the occasion of Lord Lucifer's son's birthday."

She must have noticed my blank face. It would be hard not to notice. I didn't know about it. No one told me.

"Oh."

"You really didn't know?"

"Ughh, I came back yesterday and missed Father during the day. They must have forgotten to notify me about it. What's this about? Any prize? Mandatory participation?"

She let out a sigh. "Not really. At best there would be some monetary prize but the more important thing is the fame. As for participation, it's not mandatory."

"Ah, then I'll pass." I shrugged.

"Why?"

"Hmm, I don't need money. Fame can always be earned later. And last but not the least, Rias will be participating for the Gremory House so I'd rather pass. I don't like exhibiting my skills unless I have to. Will you be participating? If so then I'll cheer for you." I smiled.

"But you will be getting the honour of being the best among the youngest generation." She repeated.

"Oh and what would that do? Tell me one thing, a solid thing which the said honour could give me?"

"You could be a hero, an idol for the new generation of devils."

This girl thinks too much.

"Do you know what people like the best to see about a hero?"

"Seeing them win?"

"No… seeing them fall so that they can gloat and then cheer on the winner as the new hero. People do get bored often. They need a change of heroes and I have no intention of becoming their chew toy. Also, you haven't seen Rias fight. If she does, there's no chance anyone else would win."

This got her attention. "Is she even stronger than you?"

"I have never won a single serious spar against her."

Technically, we have never gone all out against each other. A fight between two Ultimate Class and above beings would cause too much chaos so what I said was true.

Merging with the soul apparently increased her potential too. She was beyond Satan Class being at her peak in her previous life. This time though, she would reach Super Class for sure.

At this time, I saw her being harassed by Riser. That bastard was trying to get handsy with her.

"Come with me." I asked Latia. "I just need to confirm if she will be entering or not."

- Rias -

She moved to the side to greet Sona while trying to avoid Riser's hands which were trying to slip down her back to her ass. He was getting annoying and she was trying to avoid using magic in this place so as to not catch the attention of anyone.

"Rias." She heard a familiar voice and saw Flinn walking towards them with Latia. Sensing the opportunity he provided her, she went ahead and greeted them.

"Yes."

"Will you be participating in the fight today?"

"Fight? Oh, the exhibition matches? Yes. Father told me about them. You missed him in the morning and I got busy so couldn't tell you. Didn't anyone else tell you?"

"No. So, are you participating? If yes then, I will pass." She had the urge to smile because she had already expected this reply from him before he even spoke.

Sona was looking forward to fighting him and it was just like him to not even participate. He looked at the girl's face and she was looking completely off guard, not even expecting this reply. Latia on the other hand looked annoyed.

She must be quite disappointed.

She was about to reply when an obnoxious laugh suddenly interrupted them. "Haha you all don't have to try so hard. Dear Rias, while I appreciate your enthusiasm to participate in the exhibition matches, I advise you not to waste your time. Obviously, the Phenex bloodline will be the one to win."

She rolled her eyes internally and looked at Flinn who was not even pretending to care, openly rolling his eyes. He did get quite annoyed, completely different from his normal personality when it came to Riser and she found it quite adorable too.

Thankfully, before he could do anything further to annoy them, he was called away by his father.

"Why are you not participating?" Sona asked, hurriedly. Poor Sona was practising for a long time to try getting that one win against him.

"I… have a stomach ache."

"What?" The girl completely blanked out, not expecting such a reply.

"I think I ate something wrong yesterday and I am not feeling well right now. I apologise for disappointing you, Heiress Sitri."

"Devils don't get stomach aches. They can easily be fixed by our Demonic Power."

"What! Oh no. Then what is this? Do I have some kind of disease or maybe some kind of parasite? I need to get this checked, I am sorry, I will have to leave early today."

The look on Sona's face was worth watching. She only needed to stomp her legs in frustration to show just how angry she was.

"I am afraid you have to get healed later. Father asked me to tell you that you cannot skip the exhibition." She laughed seeing him blanche.

"Hmph, then I will see you in the fight." Sona quickly said as she left.

"She is not going to let me go, is she?"

"I don't think so."

"Heh, trying to run away again, Flinn Gremory? Then again it's understandable. A spare like you should know better than to overestimate your ability. Don't worry. I will let you pass….well if your sister and fiance agree to repay the favour."

Zephyrdor Glasya-Labolas.

Some people were just as annoying in every world.

"Nothing much. Just suck my di…"

"You know what Rias? I have decided. I will fight. I haven't exercised in a long time." Flinn said, completely ignoring the boy.

"Eh, got some courage and are you just trying to show off in front of your little fiance, blood halflin…"

"Zephyrdor Glasya-Labolas. Could you leave us alone… you are being annoying." She stopped him, her own anger rising. Maybe a little trauma is necessary for people like these to think before they speak.

"What, or will you complain to your brother? Is the Princess of the Gremory going to cry? I was giving you a chance to know a real man before you get spoiled by that chicken shit. No worries, I bet he will be willing to share with how much he brags about his future harem."

"Leave." She narrowed her eyes as her demonic power seeped in lightly, pressuring the guy.

He seemed to have gotten the message and hurried out.

She did notice Flinn's eyes narrowing in anger.

Poor Latia seemed to be confused about what was going on.

- Flinn -

The exhibition matches are basically a dick measuring contest for the adults by showing their children off. And most of the children were just that… dicks.

Now, how to fight them.

I didn't want to show all my Skills but I do need to show some. All of them are Mid Class so I could defeat them using magic alone but… that bastard needed to suffer.

Killing him would cause problems.

Hmm. Decided.

The lots were made at random and maybe the Gremory Trait was really Luck.

I was matched with the one I wanted to, Zephyrdor Glasya-Labolas.

The Glasya-Labolas trait was Barrier Magic and their biggest claim to fame was the Satan Asmodeus, from their clan.

I summoned a sword from my inventory. Using the metal vessel would be overkill.

- Sona Sitri -

She watched as Flinn walked towards the middle of the field, carefully so as to not miss anything. Knowing the enemy was half the battle.

This time she wouldn't lose.

He summoned a sword as he walked.

"Does Flinn use swords?"

"He used to practise swordsmanship when he was younger but then he started concentrating on magic more." Rias explained, completely unbothered.

On the field, Zephyrdor had already created a barrier around himself and was laughing. They could even hear the comments from this place.

"Hahahaha so slow. And who uses a sword when you have magic. A barbarian. Do you think your tiny sword can pierce my barrier? This is the Barrier of the Glasya-Labolas, the strongest in the underworld. This is my Absolute Defen…"

BOOOOOOOOOM

The next moment there was a heavy sound and Zephyrdor was lodged in the wall surrounding the field while Flinn was standing in the place where Zephyrdor previously stood, the barrier sliced in two and still dissipating.

"I'm sorry, Absolute what?" He straightened up and asked while storing the sword away.

She was sure that she was looking at him the entire time. Her eyes didn't leave his figure even for a moment and she missed him. She still suddenly found him standing dozens of metres away from his previous spot.

The entire place was silenced. The only other sound she could hear around her was of Rias sipping her drink, unbothered.

She looked at Zephyrdor and saw that he had several cuts on his body, his clothes were tattered, leaving him practically naked. She could only verify that he was still breathing so not dead yet.

Flinn turned around and walked out of the stadium… only to slip and fall before leaving. He then got up and held his leg. "Referee, I would like to resign. I think I sprained my ankle."

….

….

"Aghhhhhhhhh!"

- Rias -

She had the urge to laugh at the dumbfounded faces of the people. If they thought they could force her Flinn to do something he didn't want to, then they had truly underestimated him.

She watched him as Shuri carried him back to the stands and suggested treating his leg.

Sona on the other hand… Poor girl had really lost it this time.

The winner of the match, Zephyrdor, on technicality, because the Referee hadn't finished counting before Flinn resigned, was still unconscious.

But it seems that Onee-chan has to pick up the slack for her cute little brother.

- Flinn -

The party ended soon after the exhibition matches.

The winner was Rias as I had predicted.

She had utterly decimated everyone in the competition, even Riser who was a shivering mess by the end of the exhibition match.

I was trying hard to control my smile at the time.

He will know better to keep his hands in check from the next time. Zephyrdor, though, was healed by a Phenex Tear but still kept howling.

Yoriichi was a madlad who cut Muzan so badly that he kept burning for a whole five hundred years.

And while I did hold back, I made sure that the cut on his dick burned.

He couldn't fight in the next round or he would have faced the wrath of the mad dog Sona Sitri who looked as if possessed for some reason.

I wonder who could get on her nerves so much. I would ask them for tips.

They didn't exactly ask me about the technique unlike what I had expected because it was swordsmanship. Even Father didn't tell me anything. He wanted us to show the power of the Gremory house and both of us did so. These people really underestimated swordsmanship or physical techniques a lot.

I felt arms wrap around me as I relaxed back into soft mountains of flesh. Rias, Shuri and I were in the bath together before we went to bed.

She was quite happy today.

"Flinn-kun has become quite a star in today's matches." Shuri said.

"Umm umm. I expect no less from my cute brother. Did you see their faces, especially that Zephyrdor? Absolute Defence heh. Still, it was quite adorable to see Flinn getting so protective." She cooed in my ear before taking a small bite at my earlobes.

"Yup. Flinn-kun was quite manly today. I wonder when he will be this forceful with me~" Shuri rubbed her breasts to my sides, my arm buried in her valley, as she whispered the last part in my ears. Although with the Devil physique, it was clearly heard by everyone.

Needless to say that with this much teasing, little Flinn was standing in attention.

"But Rias-chan was quite amazing too. I felt very excited during your match against the Phenex boy. His screams were amazing. Too bad that he couldn't last much even with the so-called strongest bloodline in the Underworld. The ones with the Phenex Bloodline could make for the best toys with their healing." She licked the corner of her lips.

Shuri was quite a sadist. Although she never tried anything on me when I told her I wasn't into that sort of thing, her sadistic sides slipped out sometimes and it was unnaturally hot.

My cock twitched.

"No accidentally seducing my Flinn. I already have dibs, Shuri." Rias hugged me tighter, if that was even possible.

"Did Father tell you anything about putting Riser in his place?" I asked, when all of us calmed down a little bit.

"Hmm not really."

"Although, Riser did… he said that Rias-chan would pay for it and that he would make sure she knows when they get married." Shuri laughed.

"It wouldn't change anything. Rias would still be the Heiress and Riser the third son. The only reason that farce of a contract is even in place is because of Father's fetish of Bloodlines."

"Still, I wonder how and why the Phenex even agreed to this kind of contract. It looks pretty one sided." I asked.

"No idea. I haven't seen the contract itself. I only know the clause, roughly."

This made me pause. I was under the impression that she knew what was in the contract all this time and was unbothered about it. Turns out she didn't know anything.

"It doesn't matter anyway, right? With our speed, we will be out before I am even of the legal marriageable age. So we don't need to bother about it."

Well, that's true but it still made me curious.

As we all got out and lay on our bed, I was still thinking about this.

"Still mad about today?" She asked, seeing me quiet.

I kept my eyes closed but spoke. "I really wanted to beat that bastard so bad… He was trying to moles…" I couldn't finish my sentence as I felt something soft on my lips. My eyes opened wide at the sudden feeling.

"Your reward for coming to my rescue." She whispered once more while I still remained open-mouthed.

When I did regain my facilities, I did the first thing which came to my mind - got on top of her and smashed my lips on hers.

She giggled but accepted me nonetheless as her arms wrapped around me.

"Oh my…" I didn't even care about what Shuri was saying.

While we held back because of her younger body. Even the Transformation Technique only changed her looks, not her original physique. She was still young and I didn't want to do anything to hurt her so we decided to wait until we were a little older.

I, from my side, wanted to give her the chance to get out from the trauma of her previous life and take this step herself but now that she has… there was no stopping us.

My tongue entered her mouth and wrestled with her own as she wrapped her legs around me, pulling me in.

We only separated when both of us had to catch breaths which due to our power was quite long.

Yes. I am not going to let anyone take her away from me.

That fucking bastard.

No wonder the Phenex agreed so easily to such a ridiculous contract.

It turns out Sirzechs was involved in this mess all along.

Then again, the time of the contract was quite convenient too. When Milicas was three years old.

"Calm down, Flinn. It doesn't change anything." Rias tried calming me down but I was still angry.

"He could have just asked, you know….just asked once first. But he went behind us to screw you and Father….he agreed with this. Seriously, I am done with this." I had no good feelings regarding them till now but it was still neutral. But this….

"So, he actually made another contract with Ravel Phenex and Milicas in which she will become Lady Gremory which means Milicas will become Lord Gremory, but…." Shuri asked.

"And that means, Rias will have to leave. If he had tried to place Milicas as the Gremory Heir directly, many people would have raised voices about the Lucifer interfering so blatantly in the affairs of Houses but if Rias were to be married out due to some loophole or breaking the contract…." I completed.

"No one will be able to call him out and the blame will only be on Rias." That said, Rias will be under several restrictions if the contract was broken from her side, which includes becoming a member of Riser's peerage and basically his plaything.

I was feeling off since I had heard of the contract and decided to check. It wasn't exactly tough.

Shinobi were known for their espionage skills. Not to mention, the Eternal Mangekyo Sharingan on a few people helped a lot too.

Turns out that Lord Phenex had several deals out of this. With Sirzechs, with Father and ….with Lord Agares.

Father wanted to get a Power of destruction and Phenex Bloodline either way. He didn't care if it was Rias or always Milicas, so he left a clause which would get either results. Sirzechs was behind it along with his wife.

Doing all this….just to maintain the farce of Sirzechs being uninvolved….

"Flinn, we need to concentrate on the main goal first. The contract cannot be used until I'm eighteen."

I took a deep breath and calmed myself but the anger was hard to let go.

I really didn't want to do anything to them before leaving the world but now…

"You are right. I will complete the spell in a year or two at best."

We returned to the Human World soon and I got back to training.

My Kouen Template was almost completed

It was time to get the completion rewards.

So I did just what was needed. The same as before, Grayfia was sent back to bring some books while both Rias and Shuri put up a barrier.

Kouen Ren [100% complete]

Congratulations on completing the fourth Template.

Please select the upgrade:

Enhance Agares Djinn

Enhance Astaroth Djinn

Enhance Phenex Djinn

Enhance Swordsmanship

Enhance Magoi Reserves

Enhance Intelligence

Enhance Magoi Control

The rewards were quite tempting.

My swordsmanship is quite good and with Yoriichi's Talent, will only get better over time.

Intelligence. Sora did more than enough.

Magoi Reserves weren't exactly needed with my own Energy Reserves along with the Rinnegan and Astaroth.

The Djinn actually gives me the power to absorb Flames and Heat and change them into Magoi, basically restoring my reserves almost endlessly.

Not to mention the inexhaustible flames of the Djinn.

Phenex' healing is good enough.

I finally chose to enhance Astaroth.

Getting immunity against one element and a great way to attack and restore my power was much better than any other options on the list.

I felt my bond with Astaroth get stronger.

Randomising the next Character Template.

Several characters passed in front of me and the counter finally stopped at… Red Hair Shanks.

Character Template Selected: Red Hair Shanks

Integrating the Character Template. Current Progress - 0%.

Shanks. I recalled the memories.

An Emperor of the Seas.

This one had the thing I needed the most.

A strong physique.

People from the one piece world have ridiculous physiques. I mean punching islands to pieces. And Shanks was top of the line too.

Chakra was also made up of Physical and Spiritual Energies. A stronger body would mean more chakra because I didn't lack spiritual energy due to the Sora and Kouen Templates.

And when matched with Yoriichi's Demon Slayer Mark… Yes. Shanks is the perfect one.

As a swordsman, it will help me integrate faster with the Template. Haki looks quite convenient too.

This time around, I didn't pass out so I checked my body first.

It was safe to say that I was beyond Grayfia now. Nowhere close to Sirzechs or Ajuka but beyond even Serafall.

I wonder how much chaos will be caused if they realise that there was a thirteen year old beyond Satan Class Devil.

Rias and Shuri checked me for any problems and found nothing.

"So, what plans do we have next?" I asked.

"I recently heard some very interesting news and want to check it out." She smiled slyly.

"Why are we in Italy again? I am really confused about this surprise of yours."

"There has been some news of a witch in this area. The Church is doing everything they can to kill her but she has been able to remain free of their grasp. It's said that she was responsible for the massacre of several church higher ups as well as children."

"So? I don't think you would like this kind of person?" This was a line she never crossed and that was children.

"I am more interested in the witch herself than what the Church says about her."

"Oh! What's her name?" I asked as I was quite curious.

"Griselda Quarta. She was a friend and the guardian of Xenovia. I want to see what kind of person she is in this world. As for the rumours spread by the church, they were hardly worth anything in my world, let alone this one."

"Well… point."

It took us three days to find the place and right on time.

We could only find it because of the fight raging on here.

Light and holy weapons used so blatantly would be hard to ignore for anyone.

I brought us inside my Kamui dimension and spied on the situation.

On one side was a blonde woman who looked to be in her early twenties and on the other side, there were church people headed by a guy who looked to be eighteen or so.

"That's Dulio Gueseldo. The user of Zenith Tempest." Rias supplied helpfully.

The second ranked Longinus with the power to control the weather of the whole world.

I won't lie and say that I wasn't tempted. This was the best Sacred Gear for me.

Rinnegan's five element affinity.

Astaroth can absorb the flames for endless recharge.

I can dodge attacks and collateral damage with Kamui.

We observed the situation from the side.

"Your end has come, Heretic." The guy said as he created orbs of fire around himself.

"Heretic? I'm a heretic? It is you people who are the Heretics. Killing innocent children for no fault of their own."

"They were strayed by the words of the Devils. To even bring the thought of God being dead, they could only die for their sins." The guy said.

I didn't need to be a genius to know that this type of guy had undergone thorough brainwashing. There was no inflection in his tone which meant that he truly believed in what he was saying. Dumbass.

"So, what's the plan, Sis?"

"Can you get her out without getting hurt?"

"Simple."

"Then we save her. Make sure no one finds out about our identity."

I changed my eyes into the Rinnegan and then thought of something and smiled.

"Transformation." My figure changed into that of a six feet tall man with ten jet black feathered wings behind my back. Kokabiel of the Fallen Angels.

I saw both their eyes widening and smiled.

"Let the Fallen Angels take some credit." I could have used Baraqiel but I can't use Holy Lightning and Kokabiel is a swordsman like me so I can more or less pull it off.

Azazel has a great interest in Sacred Gears and if the Zenith Tempest were to disappear, they would know who to search for.

"I will bring her here. You two take her away. I want to try something first."

"What?"

"Zenith Tempest seems like a good Sacred Gear. Can we just extract it? After all from what I have heard, Azazel seems to be interested in those. Would make sense if he sends someone to get one."

She looked in thought then nodded. "You would need to incapacitate him first."

"Great. I was hoping for a chance to fight."

A look at Shuri's face told me that I was getting lucky tonight.

I really haven't had the chance to fight since I got stronger. I needed a good fight to know where I stand.

First of all I made several clones and sent them around the field.

Griselda was on her last leg when a wall of water rose between her and the fireball attack, saving her from death.

The explosion created a lot of steam and I took advantage of this moment to open a tear in space and send her to the place Rias and Shuri were waiting.

I landed on the ground and looked at the people below who were glaring at me. The guy, Dulio especially. His eyes were burning with hate as he saw me.

"Filth who has gone against the will of God, now you stand in the path of his judgement."

"Whose judgement exactly?" I said lightly. "Don't misunderstand. I am here for you. That girl… she was just lucky. I heard that the Church acquired a new attack Dog and Azazel wanted that trinket you have. So, why don't you be a good child and hand it over quietly? That way your deaths can be painless."

I didn't have to wait for the reply as one of the exorcists raced towards me with a sword drawn and neared my body.

I dodged to the side and slashed at his neck with a wind chakra enhanced chop. The exorcist's head flew and his sword fell down. I picked up the sword and walked forward.

The fight had started. Half the exorcists raced towards me, their swords drawn while Dulio maintained a distance and attacked alongside the others with elemental attacks.

"Almighty Push."

The attacks as well as the exorcists were blown away, leaving a huge pit where I stood.

I raised my hand. "Universal Pull."

Dulio was dragged towards me. The guy was completely caught off guard but he still threw icicles at me while creating a wall of earth between us. Too bad it didn't work. One slash of my sword and the wall was cut into half. Just in time for my shadow clones to emerge from the ground and pull the rest of the exorcists into the ground to their necks.

One solid punch to Dulio's face and he was knocked out.

….

What the fuck?

This was too easy.

I was tempted to throw some water on his face and wake him up so that he could use his Balance Breaker or something but we were on a tight schedule.

While Rias extracted his Sacred Gear, Shuri healed Griselda and I took the opportunity to change their memories to believe that they lost to Kokabiel and that Griselda Quarta is dead.

Two years have passed since our recruiting Griselda.

My first real fight was a disappointment.

A longinus was supposed to be stronger.

Anyway, Griselda was hidden away by us and we left Shadow Clones as well as Shuri to take care of her.

She was hurt quite badly and it took me using Phenex to heal everything.

Zenith Tempest was kept aside for the time being.

From what we heard, the blame went on the Fallen Angels and the Church destroyed several of their bases in the Human world.

In the end, the leaders had to gather and solve the problem themselves.

Kokabiel went rogue but not without doing something which made Shuri happy. He severely wounded Baraqiel.

My current target was Sirzechs. That bastard was trying to plot against Rias and I was going to show him why that is bad for someone's health.

But to do this, I needed the help of someone.

And who better than the one who would stab him the moment she is given a chance.

Yes. Grayfia.

We took some time to find out why exactly she was following all the orders so obediently. Rias knew her weakness.

Alcohol. It took some effort but we did get her drunk. Shuri had a way with words and their similar pasts did the work. I used the opportunity to use the Mangekyo Sharingan to enter her mindscape and found out that her Queen Piece had a failsafe that would activate if she ran away or did anything against Sirzechs. Pretty vicious if you ask me.

She couldn't tell anyone any of Sirzechs secrets or plot against him either.

Reminded me of the Tongue Seal of Danzo.

So, we did the only thing we could think of. Removed the failsafe part while keeping the piece there and offered her an opportunity to get even.

Now, if Shuri was hard, Grayfia was hell mode.

She absolutely refused to trust anyone, so it took us to show her some of our cards as well as Rias convincing her over months to get her on board.

Finally, we made a deal.

I help her get even with Sirzechs and his wife and she will follow me till the end of her life. I won't lie, I was scared out of my fucking mind when I heard the condition. Not about messing with Sirzechs. I had several ways to ruin him. I was scared at the sheer hate she had.

If she were to get the power to kill Sirzechs, she would gladly burn the Underworld to get it.

Then again, thinking about the centuries of abuse from someone for whom she left everything… yeah. I don't envy Sirzechs right now.

Our Spell was completed and we could travel to the world Rias came from in the winter equinox. Three months.

And I knew exactly what to do with this time.

- Sirzechs Lucifer -

He rushed back to his home when Diana called him urgently.

On reaching home, he saw a shaken Diana hugging Milicas tightly while being surrounded by her Peerage members.

She ran towards him and grabbed him as soon as he entered the room.

"What happened here?" he asked.

"It's her. I told you she would do something. I told you!"

Confused, he looked at her and she handed him a letter.

"She left this under Milicas' pillow. Half my peerage members were killed in their sleep."

He opened the letter with narrowed eyes and his breath got stuck as he read the contents.

'The Debt of the last four hundred years will be repaid with interest. Your little brother and sister were the first instalments. Your son will be the next. And finally, it will be your time. Sincerely, Grayfia.'

He crushed the letter in his hand and tried to feel his Queen Piece to see where she was hiding. Ajuka's backup did come in handy.

But what he got in return was just the Queen Piece with another piece of paper.

'I am Free but you will never be.'

The paper was erased with a light use of the Power of Destruction.

He summoned a Magic Circle and called for his own peerage and then his fellow Satans.

"What's the matter, Sirzechs? I am very busy." Ajuka's voice sounded from the other end.

"Grayfia found a way to remove the Evil Piece. She has gone rogue."

….

….

"I will be there." No more words were needed. Both of them understood the implications.

Next, he called his Father and checked for Rias and Flinn's statuses and found that they couldn't be reached.

"The place where Miss Rias and Master Flinn were staying was completely buried with ice. Their bodies were encased in the ice but when we tried to remove it, the entire place exploded. She had set a trap in the bodies. Souji lost an arm."

With each news he heard, his anger increased.

Maybe he really should have finished her off. The only reason he kept her was because she was a symbol. The only Lucifuge serving the current Lucifer.

Her being one of the very few Satan Class beings in the Underworld was also something he didn't want to waste.

"How did she remove the Piece? How long was she planning this? You said that she wasn't supposed to be able to do this."

"The spells had been removed for over a year now. She must have found someone for help. Probably the Old Satan Faction."

"Do you think he is making a move?" Rizevim hadn't made any moves for centuries but if he did…

"Maybe." Ajuka replied, still fiddling with the piece.

"Did you find any way to track her down? She knows too much about the Underworld."

"There is nothing here. Very few people can remove Evil Pieces. I will try to see if my sources can find anything somewhere."

He too sent his peerage away to search for Grayfia. The worst part was that he couldn't declare her rogue until it was the last option or his credibility would be questioned.

A Lucifer who couldn't even control his own queen, how would someone like that, manage the Underworld?

He took a deep breath and came out of the office and walked down.

Suddenly, he felt an attack coming towards him from the corner. Reflexively, his Power of destruction moved and the attack was erased. He turned to see Grayfia sending another attack towards him but didn't give her a chance.

'Ruin the Extinct.'

Destruction tore through her body, leaving only half of it fallen on the ground.

Really?

Was he worried about this?

Did she learn nothing in the last hundreds of years?

Coming at him so blatantly…

He looked around and saw the bewildered eyes of everyone. Yes. Him killing his Queen was supposed to be quite shocking. "Grayfia Lucifuge had gone rogue. She had killed Rias Gremory and Flinn Gremory a few hours ago. She then came here to assassinate me, as you all have already seen. Take her body away."

To his surprise, no one moved

They were just looking blankly at him, shocked.

"Did you not hear what I said? I asked you all to remove the body. She…" he turned back and shouted. "It's just a traito…" His words got stuck in his mouth.

"DIANAAAAAA!"

- Flinn -

I walked out of the Lucifer's office as the shouts echoed behind me.

Mangekyo Sharingan Genjutsu is terrifying if used wisely. Sirzechs world have shrugged off most attacks but even an instant, when used wisely can give devastating results.

They should have known better than to plot against my sister.

Walking into an alleyway, I opened a space tear and walked into the room where Grayfia was staying.

She had watched everything from the spell I was using.

"The first instalment is completed. Remember to uphold your side of the deal."

"I will."

Over the next two months, Sirzechs' life was made into a living nightmare.

He would often see people attacking him. When Ajuka guarded against this, I used shadow clones transformed into his peerage members to actually go after him.

The guy was paranoid as fuck. Even setting passwords didn't help as I could easily get them out with my genjutsu.

And finally for the last blow, we used the Sleeping Illness.

In a few months, Satan Lucifer would go into a coma. If Ajuka somehow got a cure, well… good luck.

Milicas was not hurt but Zeoticus Gremory was. He would never become a father again.

Lord Phenex was the same.

Lord Agares had encountered an accident.

Five of Sirzechs' peerage members were killed.

Grayfia Lucifuge joined my peerage as a pawn and Rias joined as my Queen.

With her current enhanced power and potential on top of the Graal, I needed my Queen piece.

Another thing which happened was that I completed my Shanks Template.

Red Hair Shanks [100% complete]

Congratulations on completing the fifth Template.

Please select the upgrade:

Enhance Observation Haki

Enhance Armament Haki

Enhance Conqueror's Haki

Enhance Swordsmanship

Enhance Physique

Enhance Stamina

Sadly it didn't let me enhance all three Haki types, so I chose to enhance Conqueror's Haki.

Randomising the next Character Template.

Several characters passed in front of me and the counter finally stopped at… Ryomen Sukuna.

Character Template Selected: Ryomen Sukuna

Integrating the Character Template. Current Progress - 0%.

This particular Template was insane as it wanted me to create as much chaos as I could. And to be honest, it couldn't have come at a better time.

With the tricks I pulled against Sirzechs, the Template thrived in the chaos, and I was already halfway through.

It was the fastest progress I had made on a template to date.

Then again, driving the leader of an entire race near crazy, whilst making all his staff think he is and then making him a vegetable was next level of chaos. Not to mention, even the slight tricks against the other Pillars increased the Template progress.

I did wonder if finishing off another Satan would complete the Template, that said it would have endangered the Devil Race as a whole.

I wanted to pay those assholes back, not ruin the entire race.

Rias and the others didn't stay idle either. They got another Longinus, the Annihilation Maker from somewhere.

Since we were declared dead in this world, we decided to take full advantage of it.

Rias used it to change her body into her adult form.

Griselda became my fourth piece, a Knight.

As Rias already had the Graal, we distributed the four Longinus we had collected among ourselves. Shuri got the Dimension Lost to protect herself as she is the Healer. Griselda is a good markswoman and needed someone to guard her at close range so Annihilation Maker there. Grayfia… well I thought she needed some good luck so she got the Telos Karma and I took the Zenith Tempest for myself.

Finally, we were ready to leave this world.

After ten whole years of grind, I was finally at a Super Devil level although barely. But the enemies in the future were going to be far stronger than a mere super devil.

But today was not the day to waste away in such thoughts.

Today was our last day in this world. And the day I was getting something I waited for a long time now.

I knew every part of Rias' body after sleeping with her for more than a decade. Every nook and cranny, every single curve and every spot where she liked being touched.

But, still, seeing her in the see-through black lace as she crawled on my body was sending very pleasant shivers down my body. She is beautiful.

My hands wrapped around her waist as she straddled me, her core firmly sitting on top of my engorged length. We could feel our breaths and even heartbeats. I decided to make the first move. Leaning in first, I captured her lips and she melted into my arms. Her arms wrapped around me and one of them took a hold of my hair, pulling me deeper into the kiss. I wholeheartedly indulged her.

My hands slipped down her back and on her bountiful ass, slipping through her panties and taking a handful of the soft flesh. She moaned and I repeated.

One of my fingers, creating little circles around her wrinkled hole. She was moving her hips and rubbing into me.

Devils were shapeshifters. We could change our bodies over time to suit our fantasies.

I had grown quite well due to this along with the help of the templates.

Physically, I was stronger than any Devil in this world. So, when I took her in my arms and lay her down on the bed, she couldn't resist. Not that she tried but still.

I tore her bra off. I was not really in the mood nor did I have the patience to unhook the damn contraption. But it freed the milky globes for my eyes to feast.

They were just perfect. Pink nubs on top of flawless milky hills. I did the only reasonable thing one could do when encountered with such an opportunity. Took one into my mouth and sucked.

My other hand went to her other peak and rubbed the nipple between my fingers.

"Mmhhh." Her grip on my hair got harder and her legs wrapped around me as she rubbed even harder.

A few minutes later, as her pink nubs had turned red due to my sucking, I moved down, leaving a trail of kisses till I reached my destination.

Her panties were drenched and I didn't want her to catch cold so I pulled them down. She raised herself to facilitate the removal.

I looked at those glistening lips with neatly trimmed crimson patch on top and placed a kiss on them.

"Ahhhh, Flinn~"

The sound of her calling my name was enough to drive me into a frenzy. I licked and sucked on her lower lips as one of my fingers found a way in.

She was tight. Extremely so. And hot, like smouldering hot.

Her core was grabbing my finger and refusing to let go.

After a few minutes, I felt her body tighten up as her thighs wrapped around me and her fingers gripped my hair tighter, pulling me in. She let out a low guttural moan as her body spasmed before going limp.

She came.

I made her cum in our first time together.

Seeing her laying there, a slight layer of sweat on her head, making her hair stick to her face. She looked absolutely exotic.

I off-handedly cleaned us and pecked softly on her lips.

This time however, she rolled me over and got on top of me as the crimson locks framing her face came down as a curtain over us. She kissed me lightly on the lips and whispered. "Now, let Onee-chan take care of you."

And I did just that.

She moved down, leaving playful kisses on entire body as my length was caught between her milky globes. She moved down and placed a kiss on my tip and I felt a shiver of pleasure run down my entire body.

My hand went to her head and caressed her crimson locks. She looked directly into my eyes as she took my tip into her mouth. So warm.

She rolled her tongue over my tip as she took me deeper into her mouth. I gripped her hair but she held my thigh and pulled more, expertly pushing back the gag reflex.

The next few minutes were the most pleasurable ones I had felt in my life.

Finally, I felt the edge approaching and gripped her hair tighter as I grunted. She understood and pulled out, just keeping the tip in her mouth as I shot ropes of my white seed into her.

She gulped it down and the scene made me stand up again. My physique was not going to let me down now.

I positioned myself on top of her, my tip at her entrance. Almost eleven years. I looked at the most important person I had in this world and couldn't describe the feeling in my heart.

"Do it." She asked me and I needed no more words.

I pushed and slipped bit by bit into her. I spotted a bit of red and looked astonished. I wasn't expecting a hymen due to the amount of exercises we used to do.

She looked at me with a smile. "I used the Graal to change my body a bit. This was a new start to our life and I wanted my Flinn's first to be every bit as special as anyone."

… this girl. Was she worried about this? Sometimes, she is too vanilla. Not that I mind. It's just one of the things which make her special. But then again, it could mean she finally decided to give a new chance to life again. If so, thenit's fine.

"I thought I told you that I am into more mature women." I leaned in to place a soft peck on her lips.

"Oh. I can do those too." She smirked as she pulled me in for a kiss.

I started with slow and steady thrusts and slowly increased my speed as she deepened the kiss. We separated with a string of saliva connecting our tongues and I focused on her breasts.

"Mmhhh ahhhhhh right there. Don't slow down, Ahhhh yes~~."

The sounds of her moans and clapping flesh echoed in the room. I reached my first climax soon but apparently, total concentration breathing was good for more than one thing. Same for the Phenex Djinn. Healing and continuing our night was something we had decided mutually.

I woke up in the morning, feeling extremely refreshed. A smile came to my face as I recalled last night. We went to sleep at five in the morning. Well, Onee-chan fainted.

Yup. I fucked her to sleep on our first night together. I fucked a Satan Class being to sleep. Even though she was not using her Demonic Power, it was still quite a feat.

The door to our room opened as Shuri came in with the morning tea.

"Ara ara, you look quite happy, Flinn-kun. Did Onee-chan make you that happy last night?" Shuri questioned.

"Better." I smirked.

She kept the tray aside and sat on the bed, beside us. "Rias-chan looks quite exhausted."

"Umm, she fainted." I replied… quite proudly and saw her eyes widen lightly. Soon, a pink hue appeared on her cheeks.

"My my I wonder if I should lend her a hand to keep you in check." She said, cupping her face with her hand. "Then again, I am not sure we can keep you by ourselves. Maybe Griselda can help. Grayfia even. Or do you want even more." She got down and whispered in my ears seductively.

"You know Shuri-chan, Onee-chan got her first dibs. I'm free to take you any time now. Don't tempt me."

"Oh, I am looking forward to it too. I still haven't rewarded you for the time when you saved Griselda."

My hands snaked around her waist and grabbed her ass taking a quick feel as I sensed Rias waking up. She however didn't mind and just laid her head on my chest and relaxed.

"When are we doing the jump?" Shuri asked me.

"Today."

"Okay."

"Are the rest also ready?"

"They are."

Griselda had almost lost faith in the church and Heaven and now considered us as her only family.

Grayfia… she will be hard to heal. She had almost closed herself to everyone. But there was something about her which attracted me to her. She actually kept her side of our deal.

I will not lie, I thought that she would kill herself after Sirzechs was taken care of but she didn't and she not only lived, she also dedicated herself to me, following each and everyone of my orders without any hesitation.

She was broken.

Maybe, the only thing which kept her sane till now was her desire for revenge. Now that she has achieved it, she just let go.

But she was now mine and I wanted my people to be happy. I did think of something.

She just needed a reason to live again. So all I needed to do was find this reason.

I checked everything several times as I prepared the spell.

"Are you sure about leaving the Boosted Gear?" I asked Rias and she nodded.

"We don't know if it can merge during the world jump or not. I'd rather not take the risk. We already have three of the top four Longinuses and the Telos Karma. We shouldn't take any unnecessary risks now."

Yes.

It was something which was entirely possible.

"Okay then. I am starting."

One of the reasons I made them my peerage members was to establish a connection between us to strengthen the anchor so that we didn't get separated.

The magic circle lit up.

Rias' Graal manifested in front of us and was placed in the middle of the circle and all of us poured our energies within.

A small portal opened in a space above the Graal and I used my Rinnegan to synchronise to the new dimension.

I pushed my chakra into my Rinnegan and the tomoe spun around wildly. "Yomotsu Hirasaka."

The space tear widened greatly and we could see everything on the other side.

Shuri took over the next part and the grey mist from the Dimension Lost stabilised the space tear.

Finally, Griselda sent a monster created with the Annihilation Maker to verify the safety of the passage.

The monsters passed through quite easily and were unharmed.

"Let's go."

And thus we stepped foot in the new world.

I left a shadow clone to blow up the entire area after we left so no one could find out what happened here. I'll never understand why Naruto never used the Shadow Clone Explosion Jutsu.

Six months had passed since we entered this world. We were thrown near the upper parts of Russia. The area was empty so our arrival was not noticed by anyone.

Over the next two months, we verified that this was the same world we wanted to come to. Then, we made identities for ourselves, left a paper trail, modified some people's memories to look as if we had lived our complete lives in this world.

Rias wanted to observe first because of the so-called Priest of the Spirit God. We needed to make sure no one like that was keeping an eye on things and notice any oddity.

So we moved near Kuoh town. According to our information, this year the Rias Gremory of this world, Onee-chan's past version was in her second year of Senior High School.

Coincidentally, Kuoh Academy was opening up for boys from this year.

"I am not doing it." There was no question about it. I was not going down that rabbit hole. Play school kids with dumb brats with IQs lesser than my dick size.

I could totally pull a school teacher.

"But among us, you are the only one who can enter the school as a student. We will be too out of place and you should also experience a normal school life. It is a good chance for you to make friends your own age." Rias asked me once more.

"Good thing I am into mature ladies so no thanks."

- Rias -

She knew he wouldn't agree to this easily.

Flinn had always been like this. He had no patience for children. His intelligence didn't make it easy either. She just wanted to let him experience a semblance of normal life after the insane things they had been through. If anyone deserved this, it was her Flinn.

But she knew of a way to change his mind. Thinking of this, she smiled slyly and sat on his lap. "Really? I thought you would be interested in some role playing. I mean I said I was not going there as a student but… I can totally pull a teacher. Are you not interested in some Teacher-Student play?"

She felt the answer under her lap, trying to poke at her.

"That's… cheating."

"Sensei is going to teach you everything~." She licked his earlobe, a habit she had developed over time.

"Even Shuri is going there as a nurse, Griselda will be the Gym Teacher and Grayfia the English Teacher."

"That's really… cheating."

The size of the bulge became bigger.

"And you know what….there is a younger version of me in the school. Don't you want to go to school with Onee-chan?" Or do you want some private classes alone with Sensei?" She whispered lightly.

The next thing she knew, she was on their bed locking lips with Flinn and her clothes, already in pieces with Dismantle, a Skill he seemed to have learned recently.

- Flinn -

This sucks.

Not the sight of Rias, I mean Kushina-Sensei teaching us Japanese, but the idiots around me.

My brain understood the dangers of Honey Trap. It's just that my dick didn't give a fuck about my brain.

I could have sent Shadow Clones in my place but I just couldn't. Not when Shuri came in with a Nurse costume and Griselda with the swimming one. Grayfia was in a formal grey suit but damn those legs. She was hot even when she was trying not to be.

So, I was caught in this and now had to deal with brats.

We did choose new names for ourselves. I actually offered and they agreed.

Rias was Kushina Uzumaki, a half Japanese who recently came back to Japan. I was her younger brother, Nagato Uzumaki. Shuri was Kurumi Tokisaki and Griselda was Lalatina Dustiness Ford and Grayfia was… Sakuya Izayoi.

Any resemblances to existing characters were purely coincidental. It had nothing to do with my fantasies. I will take these words to my grave.

Anyways, Grayfia used a spell on us which was modified by Rias using her Graal. To be honest, as long as we didn't use our Demonic Power, not even Ultimate Class beings would be able to recognise us. It was a spell developed in the future by Ajuka.

The bell rang and my quiet time was over as I was surrounded by girls.

"Nagato-kun, do you want to eat lunch together? I made too much for my bento."

"Eh, I brought sushi for lunch today. Uzumaki-kun should totally join us."

….

….

"Did you understand the last lesson? I was having a problem. Could you please explain it to me?"

These girls were relentless. Like how fucking horny could they be.

It's just that I was expressly forbidden from shooing them off.

So I pulled out the best fake smile I had practised against Sona of my world. "I am sorry but I already have plans for today. Thank you for inviting me." Obviously Shuri was a great cook and I had my own bento. "Here are my notes. You can return them to me when you are done." Also, pay attention to the teacher when she is teaching instead of staring at boys. Maybe you won't need these notes next time.

I did some help in the form of a fellow fake smiler. Kiba Yuto, the Knight of Rias, walked up to me.

"Are you going to the Kendo Club, Uzumaki-kun?"

"Yes. I was invited there." My inner swordsman couldn't stand when I saw the morons waving their shinai around like that and I went and destroyed their top members single-handedly.

This led to a meeting with the other freshman, Yuto Kiba. He was actually interested in swordsmanship. I could tell from our talks that he actually liked my swordsmanship unlike other girls who were just looking for a reason.

Onee-chan was happy with me getting along with him so I didn't mind either.

I however didn't join the club. Neither did he.

No, I was going to open my own club.

The Games Club.

My inner Sora was suppressed for a long time and I was gonna let it all out.

"Thanks for helping me out there." I thanked him as we got out of the classroom.

"Haha it's not a problem. So, what are your plans for today?"

"I will be submitting an application for a Games Club and convince the Student Council President for approval."

"Kaicho is not easy to convince. Good luck with your task."

"Are you sure you don't want to join my Games Club? It's going to be a lot of fun, you know."

"Haha I am sure it will be but I will have to apologise. I am already in the Occult Research Club."

"Oh yes. I forgot. Anyways, the door of the club will always be open for you."

"Thank you." We reached the place where he left for the Occult Research Club while I left to meet my self-proclaimed sworn enemy's counterpart.

I got to the Student's Council Room and knocked on the door.

"Come in." A voice came from inside the room and I did so.

There were four people inside the room.

The so-called Four Great Onee-sama of Kuoh academy.

Sona looked the same. Her queen was like a professional librarian. Must be her fetish.

Then there was a younger version of Shuri who was giving me similar looks.

And finally, crimson hair fluttered in the air as she turned towards me and our eyes met.

I am a connoisseur of mature ladies. You could wake me in the middle of the night and I would say the same. I would say so till the time I die.

But… sandwiches sounded good too.

Author's Note:

I hurried to get to the world jump. The main story will start from the next chapter.

The timeline is one year before the canon starts.

Many things happened in this chapter.

Big Sis is a Yandere. We found this in the last chapter but it turns out that Little Bro is not far either.

Flinn and team fucked up the previous world and left.

Adding Griselda was a whim. It worked out.

I know some people will complain about Dulio but I think this version of Dulio was highly likely when living in such a world.

Finally, Grayfia had the revenge.

Now all Flinn needs to do is seduce the silver haired waifu slowly in his own time.

The next few chapters will hopefully be a bit light hearted.

We can see Flinn messing with people, especially Sona.

Enjoy the next chapter.

Good Day, Peace Out.
