Chapter 1: I am in where?

There's many phenomena that cannot be explained in this vast world.

And reincarnation is one of many.

No shit, how can you even explain reincarnation anyway?

Ars Bune sighed while staring at his now paler, smaller hand which contrasted to his previous tan skin. Grumbling, he decides to start the day despite it being very early in the morning.

Looking at himself in the mirror, Ars stares at the reflection of a small, sickly black haired kid instead of an rugged man with wrinkles that he's used to gazing at.

Never once did he ever think that he would end up dying in his sleep. Well, it's probably due to his hardworking nature and always doing late shifts at work. Adding to his unhealthy lifestyle, no wonder that he died at the tender age of 26. But being reincarnated? He never thought of that. And on top of that, he's reincarnated in a world which is very familiar to him.

It has been 1 week since his arrival in this world, waking up in front of hysterical maids who are hysterical because their young lord is finally awakened from slumber and was thought to be dead.

Well, actually they were right. The original owner of this body is already dead, leaving a new Ars Bune to replace the old, weak Ars Bune. Apparently the previous Ars Bune had some sort of complication with his clan trait and thus, leaving him as a sickly boy from a young age. And it seems due to his weak constitution, he caught the sleeping disease a few months ago.

From what he heard from the maids, Both parents actually did something that helped to stabilise his condition. Unfortunately, it was a bad choice. And this body ended up dying due to whatever they did. On top of that, both parents were also found dead in their room not too long after. Presumably taking suicide due to shock and despair of their child's demise.

"Imagine being reincarnated in the world of DxD." spoke Ars while walking in the long corridor of his house towards the dining room.

Highschool DxD, a world where the protagonist is so obsessed with breasts he causes widespread shenanigans with that obsession. Ars snorted when he remembered how Issei managed to archive Balance Breaker.

By poking Rias's boobs.

Yeah, what a bullshit way to gain power.

While he respected Issei despite his perverseness, there's no way that he will let the same shit happen again, not with him in the DxD world. But that will be a future thing for him to drill some common sense into his brain.

For now, Ars is more focused on getting stronger quickly so he wouldn't get any trouble for anything coming across him later. Call him paranoid or shit, but Ars is well versed with most of the dangers beneath the story that show lots of breasts and naked bodies.

Fallen Angels, Kokabiel, Old Satan Faction, Khaos Brigade, Qlippoth.

Trihexa, fricking Trihexa.

Just ask Ars if they ever actually asked him, he would list every single dangerous aspect in this world. And people just told him that DxD is only for waifus and boobs.

Idiots, all of them.

The only advantages that he has is his knowledge about everything that occurred in the future. Which Ars will use it and abuse it selfishly. He had already died once, there will be no second time.

After researching and looking for information from the Bune library, the place that Ars complains about how it is so dusty as if never been touched for a long time, he learns that he's in the same generation as the main cast in the remaining 34 pillars. Which includes the likes of Rias Gremory, Sona Sitri, Sairaorg Bael, Seekvaira Agares, and other pillar heirs. But there is a little problem.

The House of Bune has already been considered on the decline by the Devil Government due to the fact that most of the house members perished in the Devil Civil War.

And that's clearly reflected on how the current Bune house is so dilapidated as it is now. Partly due to him being the only remaining living pure-blooded Bune clan member, along with the one remaining maid that is still working here. Ars can remember the time he had to clean his own shitty room by himself due to the lack of workers.

What's even worse, The Bune household had almost been declared as an extinct clan a few days before his awakening due to the apparent news of the death of the remaining two pure-blooded devils from the Bune household that were found dead in their residence. And the remaining active members being himself who was hit by the sleeping disease and thus might as well be dead and Ladora Bune, who is shunned by Devil Society due to having mixed blood.

And on top of that, the higher ups clearly did not bother to check his condition and just immediately declared the extinct status as it is already a normal situation for them to enact the extinct status.

Ars had to reconfirm his alive status to the government to undo that. And that is not what he wants to remember given how many shits he had to do. It took almost a day and a half before he managed to unfreeze his family assets and reclaim his status as the Bune heir. But there's a downside due to his parents death as things are not looking good for Ars. Some families decide to withdraw their support for the Bune household, claiming that it is not worth supporting a near-extinct house. And the only way for Ars to obtain support from various Devil politicians or current four Satan, is by having an achievement worthy to be acknowledged.

But at the same time, Ars has no plan to join politics. His experience when dealing with a bunch of greedy higher ups during his previous life taught him to never interact with those hyenas. But given the condition, the other option is much better for Ars.

Getting stronger and proving his worth to Devil Society.

Being a strong devil and participating in various tournaments such as Rating Games would help his standing in Devil Society immensely. It also increases his chance of surviving in this world.

"But in order to achieve that, I need a strong peerage." muttered Ars as he flips a book page about various names of devils that are available to recruit. "Not to mention, I also need to increase my training regime to stabilise this body."

Ars is not ignorant about his body's condition. Despite him being reincarnated in this body and surviving from blood complications, the Doctor that took care of his health told him that his blood condition is still unstable and can cause immense pain at any time. Also for now, there is no medicine that can help his condition. Using Phenex Tears is also not an option due to his house being in decline.

"So much for my luck, why the hell god-Shit!" Ars stopped due to searing pain that reverberated in his head. Cursing himself for forgetting about Devil weakness with light and anything related to the creator. Even mentioning his name causes immense pain. Sighing after the pain subsided, Ars then continues flipping the book, hoping to find any good candidate for his future peerage.

"Recruiting a peerage from the main cast is a no-no given how I don't want to deal with their shitty circumstances. Issei can deal with it for all I care." muttered Ars as he sighed and dropped the book. "There's no good candidates at all. All of them just ranged from reincarnated devil or low-to-middle class devil with average ability."

There's also numerous high-class devils that are available on the list, but their price is on what Ars can purchase with his remaining inheritance. As Ars still needs to maintain the condition of his house, no matter how dirty and inhabitable it is.

Standing up, Ars then left the dusty library to begin his daily training regime.

"Young Lord!"

Ars turned his head on a familiar sound as a figure of petite maid took a quick step towards him. Ars recognized her voice anyway.

"Yes Milia?" asked Ars as the maid quickly put her hands on his shoulders.

"What are you doing in here! You should be resting in bed!" spoke Milia with a frantic expression, making Ars roll his eyes. Leave it to Milia to be hysterical as always.

But Ars cannot really scold her for her frantical nature and how it is usually impolite for a mere maid to touch her master. After all, Milia now is one of few maids left that are still working for me.

After the death of his parents and the Bune Household being declared as an extinct house prior to his awakening, many workers quickly left their job from their position as Bune vassals. Worse, due to the currently still active Bune at that time being Ladora Bune who is considered unfit to inherit the lord title and me being unconscious for a few months, making their loyalty to the Bune household quickly vanish and just left immediately.

Ars is one hundred percent sure those greedy bastards are just laughing at me and my parents fate as they have valid reason to increase their pocket, damned hyenas. Even with him being awakened and reclaiming the family's assets it still speaks of danger to himself. Even if Devils are already governed with written rules and formal laws, their very core is still respecting strength above all others.

Having a household that only has one family member currently active and one exiled member is a sign of weakness. Ars is pretty sure those greedy bastards are now plotting to sway him with promises in order for him to waste all of Bune's family assets so they just can declare bankruptcy and write the Bune household as an extinct house.

Thankfully, a helping hand comes in the form of Sirzechs fucking Lucifer. He swiftly dealt with many affairs and current Bune status along with assigning Ars with regent from his peerage until Ars is capable enough.

Okita Souji is a pleasant man to talk to as he is pretty much chilling in his duty to do paperwork for the Bune household.

Too bad he didn't come often as he just comes whenever Ars needs him for paperwork.

How he manages to do it at blitzing speed is still a mystery to Ars.

Okita Souji did inspire Ars to be like Sirzechs Lucifer. As the reason why Sirzechs Lucifer and Ajuka Beelzebub are so feared by the remaining pillars. Not because of their position as members of Four Great Satans.

It's just that both of them are ridiculously strong that even the Devil government has to avoid getting caught on their bad side.

And Ars wanted to reach that level of strength.

Not for reclaiming his inheritance

Nor to prove himself.

A simple reason. Ars just want to survive in this world.

Despite its premise as a story filled with lecherous moments between the main character and the target girls, this world holds a significant amount of danger beneath. Lurking on behind the curtains.

That's the reason why Ars begins his training soon after he wakes up. The strong are the ones who'll survive.

"I am going outside to train." answered Ars simply. Earning himself a hard glare from his maid.

"Absolutely not!" chimed Milia as she took Ars's right arm to drag him back to his bedroom. "Remember the last time you did that alone without anyone? You are almost dying due to your condition! As a loyal maid of the Bune household, I forbid you to do anything strenuous!"

Ars only rolled his eyes while taking his arm from Milia's grip. "While your concern is appreciated, I will still go outside to train." Ars then left immediately without paying the slightest amount of how Milia keeps yelling at him on his back.

He has bigger priorities to get stronger faster.

=Scene Break=

Milia sighed loudly at her master's current state. "I've told you before, young lord…"

Truthfully, this scene is already an ordinary scene that always happens after Ars has awakened. Seeing her master lying on the ground, exhausted, she cannot help but take a towel that she prepares alongside a bottle of water, approaching her master while starting to caress his sweaty face.

Ars did not stop her, partly due to how exhausted he is currently.

"That's not… An option…" spoke Ars with laboured breath. "The sooner… I am getting stronger… The faster I can deal… With our house condi…tion…"

Milia frowned while helping Ars to stand, watching him gulp the entire bottle of water in a flash. "I understand your concern for the current Bune household, young lord. But you also need to pay attention to your body condition first."

Ars frowned but didn't rebuke what his maid just said.

"I'll manage it, Milia."

"No, you aren't." spoke Milia, voicing her doubt.

"I am serious." rebutted Ars. "I will overcome this shitty condition sooner or later. I just need to push my body further."

Ars didn't even budge with how harsh the glare that Milia sent to him. Both are not spoken anymore to each other, merely walks away from Bune household's yard while Milia's carrying Ars limp body on her shoulders. She even didn't say her usual greeting while leaving Ars in the master bedroom, the ones that he uses after both his parents are dead.

Ars sighed as he heard how Milia is closing the door with a little more force than it should be.

But he can understand how concerned his maid is to him. Something that he's always grateful for having Milia stayed whereas the other maids left after discovering the fate that befell the House.

Ars did not blame them.

Most of them are low-class Devils who are working for their daily needs. And any rumours that will affect their daily income would make them panicked. And working for a house that is declared as extinct is not what they will continue as there's no point if they didn't earn any wages.

Throwing away his wet clothes and changing to a fresh set, Ars just threw his tired body on a soft mattress, trying to sleep.

After a few moments, Ars realised that he's unable to sleep due to his mind constantly thinking about the possible future and what he must do to survive.

Sighing loudly, Ars reluctantly awakened from his comfy bed and decided to sit on the table in the master bedroom, resuming his peerage scouting progress and hoping that he could find a good one . But as the time passed, Ars began to doubt that he would ever recruit someone from this list. his eyes narrowed as he read the paper which consisted of all listed peerages that have been narrowed by their abilities and their price.

The low and middle classes are mostly useless, even after the listing process.

While the higher ones are too expensive and will give his remaining wealth a huge dent.

All are the same as his previous ones.

Clicking his tongue, Ars dropped the paper list while pinching his nose. "Shitty list with shit ton of prices. None of them are worthy of recruiting even the higher ones."

Ars began to try to remember any possible cast that he can recruit to his peerage.

"Kuroka is definitely off the list. While it is possible, recruiting her is too risky." murmured Ars as he began to list the possible DxD cast for recruiting. "Anyone that is in Rias's future peerage like Akeno, Shirone, or even Kiba is out of question as I didn't want to deal with them. And also I didn't want to deal with that shitty Diodora this early with recruiting Asia."

Adding on that, Rias has shitty taste in naming people.

As he keeps writing and thinking for any possible members, his eyes suddenly widen as he remembers a particular character that does not have much screen time but immense potential to be his peerage member.

Ingvild Leviathan.

The descendant from the Original Leviathan and also the holder of Longinus Nereid Kyrie.

"If I play my cards right, I can recruit her to be part of my peerage much earlier." And having Ingvild in his peerage is also a bonus, given her Longinus can enhance or weaken dragons, something that could be crucial for his plan later. "But the hard part is that I have no idea where her current location is. As her existence is hidden, even from that bitch Katerea and the Old Satan Faction." pondered Ars while contemplating what he could do to recruit her.

"Not to mention, she's Satan class by default, so I need to be stronger if I want to recruit her." Ars said, realised that he needed to train even harder than before. "And not to mention, my body also needs extra care." spoke Ars with a disdained tone when he reminded himself of his shitty condition.

Deciding that he had enough, Ars tiredly left the worktable and just threw his body on the soft mattress. As sleep quickly overtook his consciousness.

He will think again about recruiting Ingvild tomorrow.

=Scene Break=

Ars stood frozen on his feet.

In front of him, Milia is also in the same state, albeit sweating profusely as she took a defensive stance to defend her master.

'How? Why?'

His brain cannot proceed with this unexpected situation. Of anything that could possibly happen, this is not what he expected in the morning.

"Hey brat."

'Why, Why is he-'

Ars cannot move even one finger, too afraid with someone, with the thing that stood in front of his house now.

"I know that this is really sudden for you, but-"

'Why is he here…?!'

Even Milia that stood in front of him is unable to perform any coherent sentences, as she is also too terrified with the being that stood before her.

After all,

"How about taking a long trip with me? You're coming with me as a side bonus your blood mutation will cease being an issue."

'Why is Crom Cruach standing in front of my house?!'

"You woman will simply tell anyone who asks that the brat went on a training journey with a teacher. If you by chance recognize who I am you will not reveal it. Failure to comply will end in the brat's death."

This is something that he can barely comprehend. But little does Ars know, he just met an individual that would be of great aid to his future.
