Ritsuka Fujimaru is many things,

A high school student in the last year of high school,

Member of school volley ball club,

A Tokusatsu, Mecha, and Magical Girl fans,

Gacha game addict, which thankfully he able to hold his wallet most of the time…unlike his sister,

A casual anime enjoyer,

and a fraternal twin big brother by 10 second no matter how much Rikka denied it!

He considered his appearance as 'average', even with his black unkempt hair and sky blue eyes which can charm anyone the spending time with him. His body also quite fit for someone his age which something that he proud off!

Oh lets not forgot he also have a dream to have his own bakery in the future!

He got no tragic backstory, his life as ordinary as it can. He got a loving parent and a lovely sister. If there is something memorable about his past he can only remember one thing, it was the experience taking care his elderly neighbor along with his sister 1 week before his death

The old man family already gone and no helper available which ticked the Fujimaru siblings off but the old man is content just having someone to talks with at the end of their live

To be honest that accident shape the Fujimaru sibling view toward life. That they should celebrate good events when they happen and try to live a contented life even with no reward given to them before death

So yeah, Ritsuka is just regular high schooler that you can find anywhere

Imagine his surprise when suddenly a blue box appear in front of him

[Disclaimer!]

[Due to the growing number whiny edge-lord in existence that get temper tantrum when something didn't happen as they expected, blaming on their sponsor, and some innocent passerby when it clearly was their own fault, any potential user of this system required to read this!]

[By pressing the 'Yes' button, you will agree to the term and understand the warning below! If you can't accept it just press the 'No' button!]

[Your life will be watched by your sponsor as part his entertainment. This will be true as long you are using this system. This system is not charity. If you want privacy make one yourself!]

[Cute is Justice!]

[The sponsor did not responsible for anything that happened to you! It was either the consequence your action or something that just will happen regardless system exist or not. Please think it for yourself the ramification of this statement!]

[Akane Kurosawa is best girl!]

[Do individual Ritsuka Fujimaru willing to install DxD Devil Job System ver 7.28?]

[Yes][No]

Honestly Ritsuka is dumbfounded. He really can't make ways about the blue box in front of him

As an anime enjoyer of course he know that it was a System thanks to various Gamer story that flooded the market but as someone that live in age of information, in modern part of city where superstition almost like a dying breed, the fact it even exist literally turning his understanding to the world upside down

"Am I dreaming?" He proceeded to pinch his face, it hurt.

Not convinced Ritsuka decide observe the details of his room, lucid dream exist and while he never experience it, various 'expert' on the internet always say you can't observe details inside a dream

"Seeing that I can actually interact with my room in such detail…"

Finally Ritsuka admitted it, the floating blue box in front of him is real

"So what should I do?"

As someone that living in age of information where privacy is sought, the statement that his life will be watched as someone entertainment disturb him a lot. Ritsuka almost instinctively press the 'No' button if not for the fact one disclaimer statement catch his attention

"Something that just will happen regardless system exist or not?"

Sure the whole system thing is sketchy, so there is no way Ritsuka will believe it anything written on it of face value but he know one thing, there is no reason for whatever being that created the system need to lie to an ordinary high school student like him, in fact he can just force him to accept it and there is nothing he can do about it

So assuming the statement it true

"If I am a bored higher being that create a system to search for excitement, and I want to give the system to an individual to sate my boredom…will I choose a random dude or will choose individual that will have an interesting life even without it?"

Ritsuka is no psychologist but even he know the answer

"I see" Ritsuka grinned, at this point he already made a choice

He didn't know what life has store for him in future and may regret because of this choice but he know very well 'regret doing something' and 'regret never doing something' is a two different thing.

With that Ritsuka press the 'Yes' button without hesitation.

[Installing DxD Devil Job System ver 7.28]

Even if he rejected it here there no guarantee whoever who made the system didn't watch his life, the fact they know his life interesting is enough evidence

"Brother! Are you still asleep? I know this is weekend but Its time for breakfast!"

Her sister shout come from the dining room

"Coming! Let me wash my face first!"

"You better! Last week you promise today we will do a Haikyuu Marathon together!"

[DxD Devil Job System ver 7.28 Installation Complete!]

+Line Break+

"So what is your plan for the weekend" his father asked, after savoring his soup

Currently they are sitting on the dining table doing their breakfast together. That kinda an iron rule in the house, you can miss the other day breakfast but in weekend regardless everything you must sit on the same table

Its a countermeasure to make sure they didn't drifted out like many modern family out there. Communication is important, maybe this is a small and unimportant act to outsider but Ritsuka truly believe it was the reason why his family so harmonious

"We planned to marathon an anime" Rikka grinned "Its Haikyuu!"

"Is that so?" His mother nodded "then make sure do it after completing your homework, then I will have no problem"

"Don't worry we do that" Ritsuka replied "so is there some grocery that we needed to buy? I hate to go out later because we need to buy something"

"Some canned beer will be nice" His father replied earning a smack from his mother "Dear its weekend, and its still morning!"

His mother proceed to list some grocery needed to restock, which quite a lot

After that they start to share some interesting event in past few days, some news and gossip here and there

All in all it was a wonderful breakfast

+Line Break+

Buying grocery despite the long list and finishing their homework didn't take much time. In no time the Fujimaru sibling nailed in front of TV

It can be said Sport Anime is awesome or Haikyuu is awesome. Sure there some part that unbelievable here and there but at the end of it it was a good watch.

Ritsuka enjoy every second of it though it was quite exhausting. In the end after Season 1 over they decide called it a day. 8 hours watching marathon will do that to you

When it was over the day is about to turn dark.

Their mother asking for what is their dinner preference

"Fried Rice please!"

Dinner is also enjoyable, it can be said everyone face in the table looks exhausted but there smile in their faces

When returning his personal room Ritsuka decided to address the elephant in the room

The system

"Well I been ignoring you for the day, so lets check what is your function"

[DXD DEVIL JOB SYSTEM VER 7.28]

[JOB]

[CLIENT]

[ACHIEVEMENT]

[WISH CALCULATOR]

[SHOP]

[STATUS]

[TRAVEL]

[INVENTORY]

[Would like to play the tutorial?]

[Yes][No]

Ritsuka undoubtedly press 'Yes'. He is after all the type that will follow tutorial in any game, especially when it concerned about his life from now on

[Introduction]

[DxD Devil Job system created to emulate Devil race work from a world named Draconic Deus]

[The Devil race of that world aside from power and lifespan difference is no different than human]

[In that world Devil getting stronger by how many contract they complete. The contractor a summon a Devil state their wish and the Devil will calculate the price of their wish]

[This system created to emulate that]

"Oh, so that why it was called DxD Devil Job System" Ritsuka nodded in understanding

[Please click the Job button]

Following the instruction Ritsuka clicked it

[-Wish-

I want someone help me to write my novel!

Client: ?

Difficulty: F

]

[-Wish-

I want to be a cool outlaw!

Client:?

Difficulty: E]

[-Wish-

Anyone, someone please save Ai!

Client:?

Difficulty:A]

[This show job list, this work by hijacking Devil summoning ritual in all existence. The system work some so surface mind scan into the summoner of the devil, so user can guess the kind capability needed to complete the job

The difficulty scale with the user capability with F the lowest and S as the highest

Keep in mind due to a bug, so long it considered as Devil Summoning ritual it was hijacked by this system even the one that not supposed work in the first place]

That kinda makes sense, though there one job that catches Ritsuka eyes

"Saves Ai?" Ritsuka is quite concerned "do they in quick need of help?"

[So long the Job still posted in this tab, due to Multiverse time difference as long the user didn't take it, the summoner time will hardly passed]

"Is that so? Thats a relief" Ritsuka sighed, if he ignore the cry for help just because he can't do anything, he will feel like a piece of shit for a long time

[Next please click Client button]

After clicking it Ritsuka found it was empty

[In here is the place for the user to put their favorite Client]

Ritsuka is confused

[The Job Tab work through random scan in whole Multiverse, the chance for user to found the exact same client is infinitesimally close to zero, to mitigate that, the user can put said Client into this tab. With that the System will allocate some resources to mark that Client, with that if the Client try summon the user again it will appear in this Tab]

"That makes sense and also quite sad"

[The downsides is, unlike the Job Tab, the time in Client Tab is synchronized with the user, so if the user didn't take the job, it can be lost forever. Thought due to Multiverse sometime there is a big time difference]

"...I see" Ritsuka can understand the logic in that, if their time didn't sync it will lead to many weird thing happening.

[Next is Achievement Tab…it exactly what it says on tin. It record the user Achievement while using the system]

As casual game Ritsuka can only smile wryly

[Next is Wish Calculator. This function show calculate how much a wish supposed to cost. While at the end of the day the price of the wish depend of the user but this function is convenient to have]

"Ah that makes sense, I really don't know how to price a wish, so this function is quite convenient" Ritsuka nodded

[Next is Shop Tab, this function will is exactly what it says on the tin]

"Is this really tutorial, at this point I feel it was the creator snark toward the user" Ritsuka pointed out

[You can buy anything in the Shop using Points which can be earned by topping up your local Currency. Keep in mind Points can't be reverted back into Currency. This is to make sure you didn't wreck any world local economy]

"So I really need to think when topping up huh" Ritsuka nodded "So what kind of good available on the shop? Lets check it out"

[True Longinus - 100.000.000]

[Zenith Tempest- 90.000.000]

[Heaven Feel - 900.000.000]

[Kaleidoscope- 1000.000.000]

Seeing many price that really out his league Ritsuka quietly close the shop

[The Shop will provide goods from DxD, user world, and the worlds that connected to the user through the Client Tab]

"Oh so that another reason to use the Client Tab, I understand that much"

[Next is Status Tab]

Ritsuka open it and greeted by the lazies status screen that he ever see

[

Name: Ritsuka Fujimaru

Body: A regular high school student body, there nothing special here

Mind:So weak that a salesman can gaslit him to buy their wares

Soul: Instantly dissipates the moment his body destroyed

Number Job Completed: 0

Skill:

-100% Spirit Particle(Rayshift) Affinity

-100% Master Affinity

]

[In this tab you can keep track the capability of your stat and various skill. The System creator dislike making status board because its soon filled with ridiculous number and a letter didn't convey those stats properly, thought due to popular demand he got no choice to add one. So here we are]

"Ignoring those stat that really on point I got a skill!? And two of them!?" Ritsuka is mind blown, he always thought he is a regular every dude but to think he got 2 skill "Am I really not ordinary after all?"

With that Ritsuka click at both his skill to their use

[-100% Spirit Particle Affinity

The ability to adapt regardless world, allow the user to survive in various world and era with minimal effort

-100% Master Affinity

Universal compatibility when contracting with various Servant]

Reading it just brought more question than answer to Ritsuka. "Adaptability regardless world? Are you sure this is not the usual System Starter set? And what is a Servant?"

[User starter set are inside the Inventory Tab]

"So I do a get a starter set" Ritsuka nodded "then that means because I still not opening my inventory, all this skill is really something that I have from the start?"

[Next is Travel Function]

Ritsuka open it and as expected it was empty

[This will allow user to travel into world the connected through Client Tab. As they say, it easy to summon a Devil but is hard to drive them away!]

"I don't think the quote sound like that but that makes sense"

[And last not least the Inventory]

Ritsuka open the Inventory, a 9x5 grid appeared in front of him

[The inventory is not infinite but each box in the grid represent 1x1 meter box, so with some management even a single box can carry many things. To store bigger item you can combine many grid box into one]

"Well while its not infinite but having an inventory sure are convenient"

Ritsuka proceed picked up the box that emboldened with large letter 'Starter Set!'

"A chess piece?"

[DxD Devil have an item named 'Evil Piece' a chess set that function as a way to turn any race except gods into a Devil. In theory it was a way to solve their low population problem, in practice it was slavery with extra steps because they can do that without any consent on both side, while trying to run will turn you energy inside of you unmanageable and turn them into monster]

"So this set can turn me into a Devil?' Ritsuka frowned

[This is not Evil Piece. This is 'Transcendent Piece'. It didn't change the user races. The only thing it do is to upgrade the user talent based on the piece.]

[A Rook piece will get a great Physical Strength boost. It also make them having easier time to learn many physical related technique]

[A Knight piece will get great All Around speed and agility boost. It also make them more easier to learn any technique that needed precision]

[A Bishop piece will get a great Spiritual boost. It also make them easier in learn many theory either Science or Magic. To use it is another matter entirely]

[A Queen piece will grant all above]

[A Pawn piece will allow it user to transform it into all above piece, when deep inside enemy territory or if the user in great danger for its life]

[Last not least, the King Piece. Its have the same ability as Queen but on greater scale. Also it can eject other piece from their user by force]

[Keep in mind the piece is ejected from their user, they will lost their boost thought anything learned still retained. So unlike Evil Piece, it didn't leave permanent effect]

"I see this surprisingly well thought" Ritsuka nodded "though I can think many way to abuse this"

[Nothing if foolproof, though the creator already tries his best]

"I know and I am grateful for it"

[This is the end of tutorial. Anymore question?]

"No, the tutorial while not professional surprisingly informative"

[Tutorial Ended. Best Regards]

Now the tutorial has ended Ritsuka has many thing going on.

"Shall I try to complete a job?"

Ritsuka is still a teenager, so no matter how small it is he getting excited at the sign of supernatural. After all a men still a child until they die!

"Oh lets not forget the Transcendent Piece" Ritsuka look at the Chess set "I think I am supposed to use King one right?"

"How do I use it again?"

After a few minutes experimentation, the King Piece finally absorbed by Ritsuka body.

It was exhilarating experience, Ritsuka feel his mind now really clear, his body while there is no change outwardly now filled with power, he feel now he can do anything

"Wow just wow" Ritsuka look at his reflection in the mirror. There is no change but he know more than anyone else everything about him now different

After a while Ritsuka frown before ejecting the King piece from his body. At that moment he can feel now as if his body is a prison even though it was his original capability

"...the gap between ordinary and genius really far huh" Ritsuka mused before putting all the piece back to his inventory "unfortunately while I already accept the supernatural and the existence of Multiverse, I am not ready become a genius"

"Maybe one day but that day is not today"
