Since most reviewers are asking for me to show and bring Serafall's Peerage into the story, but her peerage has never been introduced in the Cannon DxD timeline (Except for Behemoth). How about I create a peerage for her on my own, by bringing A COUPLE characters from other series into this story?

Summary: A second chance, it's something a man like Itachi Uchiha would never think about. Reborn into a new world and earns a new life, will he learn to forgive himself, or once again he sacrifices his own life to shoulder the entire world on his shoulder, for the sake of peace? [Devil born Itachi].

[(Mostly)One-side] Itachi x Harem.

This story is inspirited by The Sharingan of the Crimson Princess made by Arcreed which he took down many months ago. I tried to contact him to get his permission for adoption, but after all this time, he still hasn't replied so I guess I will have to make my own version with what I can remember.

There'll be many similarities, but I will add my own touches in this as well.

Chapter 6

"Itachi-kun, can I talk to you for a minute?"

That request came from Venelana Gremory, the lady of the Gremory Household. Since Rias was busy with her homework from school, Itachi was currently doing some household errands for his mother and some of the other servants of the residence. Despite their insistence that he had no need to do such thing for them, he insisted on doing it anyway, simply because it's his way to spend his free time and make their job, especially his mother's, as easy as possible.

He lived a life of a criminal, where he had to kill and do many horrible things for the sake of the greater good, so Itachi felt the need to be as helpful as possible, to live his life to the fullest…worthy of the second chance that was given to him.

"Fiona, can I borrow your son for a second?" Venelana, who saw Itachi working next to her personal maid, his mother, asked with a small smile.

Itachi turned to look at his mother, who then nodded her head with a warm smile before returning her eyes back to the brown haired woman.

"Of course, Venelana-sama." His mother said with a slight bow and then urged him to go with the lady of Gremory "Go with her, sochi-kun."

"Yes, Kaa-sama." Itachi nodded and walked to his mother's mistress' side "Please, lead the way, Venelana-sama." And with that, the two of them made their way out of the room, walking to the backyard garden of Gremory castle.

There, Venelana started their conversation with a question.

"Itachi-kun, do you know that Rias is going to come to the human world next year to attend Kuoh Academy?"

"Yes, I know about that, Venelana-sama." Rias had already told him about that a few months ago. She said she wanted to live in the human world while attending Kuoh Academy so that she could fully enjoy the life of a normal high school student, but most of all, the life of a normal teenager girl. It's something Itachi had nothing against, and fully understood why she chose to do that.

"To tell you the truth, Itachi-kun, I don't want her to do that." Venelana sighed as she turned her head to the side to look at the mansion "Even I, her mother, cannot understand what she's thinking. She has everything here, and yet she wants to live in an apartment in the human world."

"Sometimes, Venelana-sama, have everything doesn't mean that you have everything you desire." Itachi said "While acknowledging her duty to take over the Gremory Household in the near future and is very proud of her name, Rias-sama wants to enjoy the full extent of her youth more than anything else, not as Rias Gremory of the Gremory Clan, but Rias Gremory a normal teenager girl. The human world, where people have no idea of her true nature, will grant her what she wishes the most. That, and she really likes Japan, I guess she will want to go and live there for a few years." Venelana let out a soft chuckle as she got reminded of her daughter's obsession.

"It's her choice, and I respect that." Venelana nodded "But still, as her mother, I can't help but feel worry about my daughter. She's not supposed to leave the house until she's mature enough, or got married." The Bael woman then looked at Itachi "Itachi-kun, what do you think of my daughter?" Itachi widened his eyes slightly at that question but answered it truthfully.

"Rias-sama is no doubt, a strong girl and she's also very smart too." For someone who was called genius alongside with Sona Sitri, there was no need for him to point that out "She cherishes her friends, the people she cares about a lot. However, she also has a very a soft and sensitive heart, something that will cause her to go into depression if someone that's close to Rias-sama dislikes her, or get hurt." It was also something a future leader like Rias shouldn't have. She had to have the will to make a tough decision for the sake of the greater goods, even if she didn't like it.

Itachi understood how hard some of them were going to be, after all, he had made the decision to follow order and slaughter his own family, in order to keep the peace between the villages of Elemental Nations. Someone as kind as Rias, who was going to take the role of the head of Gremory, would never have the will to make a decision like that, or even half as hard as that.

"I see… you understand… no, you seem to care a lot about her, don't you?" Venelana asked, smiling softly as she looked at the young boy.

"Yes, while she's no doubt someone with a higher status than me, she's a great friend of mine and I usually look at her as my little sister." Itachi said without taking a second to think "She might or might not need me in the near future, but I will never stop caring for her, and be there to do help her whenever she needs it."

"Such amazing words from you, Itachi-kun." Venelana said in amazement "Now I know why Serafall-sama wanted you to become her servant. I'm sure that you will become great in the future, Itachi-kun."

"I thank you for your compliment, Venelana-sama."

"I only speak the truth, young man…" the woman smiled before questioning "Itachi-kun, can I ask you a favor?"

"Anything, Venelana-sama." Itachi nodded his head.

"When Rias comes to the human world to live, will you follow and protect her?" asked Venelana.

Itachi nodded his head firmly "It will be my honor, Venelana-sama."

"Like you said, she's smart, but she's still young and naïve, with someone like you there to guide her and to take care of her, I have no worry." Venelana said, closing her eyes "Promise me that no matter what happen, you will always stay at her side, protect her from harm and fight for her sake."

"I promise, Venelana-sama."

He was no Uzumaki Naruto… but it wasn't just any promise, but the promise of a lifetime.

Line Break

"Itachi~."

"Itachi-sama."

Came two voices that he knew very well who the owners were.

Holding a basket of dirty clothes in his hands, the young Uchida stopped and turned to see Rias and her Queen, Himejima Akeno, walking together with smiles on their face. Over the past few months, Rias and Akeno had become best friends. They might be even closer to each other than Itachi and Rias. He was also Rias' dear friend, but he was still a boy and there were many things she could not share with him.

Six months had passed since the day Akeno became Rias' Queen, and the black haired girl had soon come out of her shy self and became more social with Rias, Itachi and the devils she met. She was kind, gentle, and could be as elegant as any high-class lady… however, when he saw her looking at a whip and collar from the window of a local shop while drooling, he knew that there was something abnormal about her personality.

And his suspicion was confirmed when he saw her taking down (torturing) a stray devil with ecstatic face while moaning like a horny woman.

Oh well, anyone had their own personality.

"Rias-sama, Akeno." Itachi greeted them with a smile.

For some reason, a week after she joined the Gremory Group, Akeno had started to address him with the honorific 'sama', something no matter how many time she didn't have to, Akeno wouldn't even consider about dropping it. She had stated that he deserved all the respects, because while Rias was the one who took her in, Itachi was the one who saved her from her own miserable way of viewing her own life, and gave her a reason to look forward to her future. That, and because he was the servant of Serafall Leviathan, he needed to be treated with respect.

Little did she know that his position as Serafall's servant was much more complicated than that.

"Hey there Itachi!" Rias smiled at him brightly, while Akeno waved her hand at him.

"It's great to see you two as well." Itachi smiled to both of them before looking at Rias "I hope your homework didn't bother you very much, Rias-sama."

"You know me, it's very easy. I can finish it in a blink and anytime I want, but my tutor didn't let me leave until I'd finished all of them." She pouted, crossing her arms on her rapidly developing chest and huffing with her eyes close "I really look forward to spending my time with you this morning, and yet…"

"Rias-sama…" Itachi called out to her and made a gesture with his hand. Rias opened her eyes and turned to look at him, which, proved to be a mistake because Itachi instantly poked Rias on her forehead.

"Eh!" Rias groaned in disappointment while Akeno was giggling "What did I do this time?"

"It's not wise to say something like that, Rias-sama. The study is very important." Itachi pointed out "Also, you shouldn't underestimate the easy tasks, it will only lead to miscalculation and…"

"Alright alright, geez Itachi." Rias waved her hand in the air and stopped him from continuing what she called: 'Itachi's usual boring lecture' that she didn't like to hear at all. His wise words usually made her feel like an idiot, instead of a genius like she was called by everyone "You have to shrug all those complicated things out of your head, you will become old and bald if you keep thinking too many complicated things like that."

"I only speak the truth, Rias-sama." Itachi shrugged his shoulders.

"Where are you going?" Rias asked curiously, looking at the basket in his hands. After finishing her homework, she had planned to spend the rest of the day with Itachi, and she was hoping that he had free time as well.

"I'm simply going to do some errands for my mother and the servants," Itachi answered, looking at the basket of clothes "I need to wash these for them."

"Mou~, you don't have to do that kind of thing, you know?" complained Rias, looking at him.

"Rias-sama, would you help your servants if they're in need of assistance?"

"I'd do it, if it's for them, I'd do my best to help," Rias answered without hesitation.

"See? It's not that different, except I'm a low-class devil and these are particularly my jobs." Itachi reasoned. Rias only nodded, understanding his intention "Plus, my mother has a lot of other works to do so… if I can make her job easier, I will be more than happy." The young boy smiled.

"That's so nice of you, Itachi-sama!" Akeno smiled and said to him, while Rias was making a mental note to tell her mother about loosening Fiona's jobs a little so Itachi wouldn't have to do it to help her.

"Anyway, I will see you two later, now I need to…"

"Let me help you Itachi!" Rias suddenly said cheerily and grabbed the basket with both hands, trying to take it from him.

"Um, Rias-sama, I'm not sure…" However, just as he expected, Rias yanked the basket of clothes from his hands, making it slip between his finger and falling down to the ground. The dirty clothes inside fell out and laid on the floor much to Rias' embarrassment.

"Ah… I'm sorry, Itachi." Rias said apologetically, lowering her head in shame.

Itachi sighed and shook his head, Rias, and her immature behaviors were truly more than a handful.

"No, it's alright." The reincarnated Uchiha shook his head and crouched down to pick up the clothes and throw them back into the basket.

"Let me help you, Itachi-sama," Akeno said and lowered herself down to pick the clothes. Rias did the same, but her expression changed when she found something very interesting among the clothes that were lying on the ground.

"Ara." Akeno gasped slightly and saw it too.

"Itachi...what's the meaning of this?" Rias calmly asked, picking up a pink panty.

"Seems like some maids wanted me to wash their underwear for them." Itachi shrugged "They probably thought it was fine to ask me since I'm a child." He casually grabbed it from her hands and put it inside the basket. He looked at Rias again and raised an eyebrow when he saw the dirty look Rias was giving him.

"Mu~, Itachi, you sure get along well with the maids," Rias said. Then, as if she had gained enlightenment from who-knows-where, she shot up to her feet and pointed her hand at Itachi. "Hah! Don't tell me! You have someone that you like among the maids?! That's the real reason why you're so eager to help them, right? It's to impress her, right?!" Rias accused, visibly shocked at the prospect of Itachi being taken away by one of her servants.

Itachi looked at Akeno, who was doing his best to hold his laughter, and then he looked back at Rias.

"No, I'm not," Itachi replied.

"Mou~, don't lie to me! I know boys who live in a castle love to have a relationship with their maids!" Rias pressed.

"… Sigh." Itachi sighed longingly before asking "What anime is that from?"

"It's not from an anime! It's from this manga called…AH!" Rias brought out a manga from her skirt's pocket, but before she could tell him the name, Itachi snatched the manga away from her. He then started reading it, and true enough the story of the manga was about an unfortunate maid who fell in love with her master and vice versa.

After reading the manga quickly, he closed it with a definite 'thump' and closed his eyes. After a few seconds, he opened his eyes and looked at Rias passively.

"Rias-sama."

"Wh-what?"

POKE

"Mou~!" Rias crossed her hands on her forehead. She had never been poked in the forehead twice in a day before.

"You really shouldn't take everything that this book tells you seriously. Many things that happen in this book is the product of the author's imaginations," Itachi explained.

"So it's not real?"

"Yes."

"So it won't happen in the real world?"

"Yes."

POKE

"Mout~, what's that for now Itachi!?" Rias asked in shock as she held her forehead with tears in her eyes. Itachi just poked her very hard, and she felt like her skin had been split open and was bleeding.

"Just feel like it." Itachi shrugged and picked up the basket, walking away without saying any other words.

Line Break

"It's so gooood!" Rias moaned happily as she licked the ice-cream Itachi bought for her. She was sitting on a bench that was close to the center fountain of an amusement park, with Itachi at her left and Akeno at her right. The black haired Queen was eating a Popsicle ice cream, while Itachi was eating some dango "It's so fun to hang out like this, neh Itachi?"

"Yes." He said with a smile, swallowing the piece of dango in his mouth "Yes it is, Rias-sama." The three of them were currently paying another visit to a town of the human world. After pretty much spending the entire morning playing, they had decided to take a rest.

"Akeno, how is your ice-cream?"

"It's very delicious, Rias-sama," Akeno replied before going back to eat her ice cream, putting it into her mouth to suck before slowly licking around with her tongue.

Somehow, someway, Itachi couldn't help but think that the way she was eating her ice-cream was very wrong, especially when she usually glanced at him and purposely let the creams drop down to her shirt.

"So delicious." Rias smiled happily and swung her legs before standing up "Neh, I'm going to buy another ice cream, would you like more dango too, Itachi?" If there's something she knew well about her best friend/secret crush, was that he really loved sweet and dango was his favorite food.

"Hm, oh, of course, Rias-sama, if you don't mind." Itachi nodded his head "Are you sure you don't want to…"

"Just sit there and enjoy it, I'll return in a moment." The crimson haired young lady shook her head before running away while waving her hand above her head, heading to the food booth they just visited a few minutes ago.

"Ara, little girl." The owner greeted her with a smile "I didn't expect you to return so soon."

"Yes… I would like another ice cream and a box of dango, please." Rias smiled and got her wallet.

However, before she could take out the money, she felt a slight tug on her skirt on the left side.

Looking at that direction, Rias' eyes widened when she saw a young girl, probably a couple of years younger than her. She was petite and had hazel-colored eyes. She was perhaps a head and a half shorter than Rias. Her white hair was short, as short as Sona's, with two long front bangs reaching her shoulders and her shorter bangs hanging loosely on her forehead.

Her clothes were rather dirty, but she was unimaginable cute.

"Who are you?" Rias asked gently with a soft smile "Are you hungry?" She asked again when she saw the small girl looking at the box of dango and ice cream. The white haired girl nodded her head, which made Rias smile but feels sad at the same time. "Here, you can ha…"

"What do you think you are doing?"

Rias instantly turned her head around and widened her eyes at what she saw.

Itachi was standing behind her, holding an older girl's wrist. She had long black hair, hazel-colored eyes like the little girl. However, what shocked Rias the most was that in her hand was Rias' wallet.

She was looking at Itachi with her eyes widen in shock.

"Sorry, but not on my…" Before he could finish his statement, the girl raised her other hand and tried to hit him in the chest. Itachi blocked it, but he didn't expect to get knocked back several feet by an invisible force.

What just happened?

"ITACHI!" Rias cried out when Itachi's back hit the ground but he instantly got back to his feet.

"Kuroka-nee sama!"

"Shirone, time to run!" Kuroka, the girl with black haired picked up her sister and placed her on her shoulders, waiting for the girl to wrap her arms around her neck before running away as fast as she could. Itachi's eyes widened a little at the speed and the grace she was moving. Surely, a normal human wouldn't be able to move like that.

"Wait here Rias-sama, I will get your wallet back for you," Itachi said and shot forward, chasing after the two girls.

"Be careful Itachi!" Rias cried out after him.

When Kuroka ran out of the park, she slowed down a little and turned her head around to see if anyone was following them.

"I think we…" but before she could say it to her sister, her eyes widened and she jumped back a few feet to avoid a kunai from hitting her "Oh for fuck sake!" she immediately turned on her heel and ran away as fast as she could when she saw Itachi jumping over the tall fence.

"Stop right there!" her eyes widened even further when she saw him easily catching up to her "Return what you steal at once!" he shouted and picked up the kunai he threw as a warning without stopping.

"Are you crazy?! NO!" She cried in shock while running "Who are you!? A fucking ninja?!"

"Kind of!" He said and threw the kunai at a car from the other side of the street, changing its direction. Kuroka's eyes nearly bulged out when she saw the weapon coming at her from the right, but she halted midway and turned right at the last moment to avoid it from cutting her cheek.

However, it turned out to be a bad decision because she was met with a dead end.

"Nowhere for you two to run now," Itachi said as he yanked his weapon out of the wall and approached the two. She felt right into his trap.

"Tch…" Kuroka growled and took a couple of steps back in caution.

"Nee-sama, I'm scared…" Shirone said with a shaky tone. There was fear in her voice as she looked at the weapon in Itachi's hand.

"Don't worry Shirone, Nee-sama will protect you." Kuroka turned her head around and said comfortingly, hoping that it was enough to calm her sister down "I'm not letting him hurt you, so don't worry."

Itachi stopped walking and looked at the two.

A smile crossed his face and Itachi decided to put the kunai away.

"Alright." Kuroka took a deep breath and turned back to face Itachi "Can you overlook this matter and walk away? We're just two homeless sisters trying to live another day in this harsh world, alright?"

"As tearful as you're trying to make it sound, no, I cannot." Itachi stated calmly "You stole from my master, and I asked you to return it back this instant."

"H-hey, that girl looks rich enough to buy this whole town, you know…"

"Sorry, still can't do that." Itachi shook his head and started approaching them again "Now, we can do this the hard way, or the easy way."

"Tch… fine!" Kuroka brought her hand back "Here's your money!" She threw the wallet to him.

Itachi raised his hand and caught it easily without even looking. However, the young Uchida soon found himself widening his eyes in surprise when he saw a pair of cat ears appeared on her head. Maybe because it was she had thought he would look at the wallet to catch it, she decided to reveal her true form.

A pair of black cat ears grew from the side of her head. Her eyes also became cat-like with slit pupils.

She then raised her hand and cast a spell. Almost instantly, the entire area was covered in a strange purple mist.

"What is…" Itachi muttered but then dropped to his knees while covering his mouth.

His body had been completely immobilized.

"I'm sorry but I will take this, nya." Kuroka walked toward him and took the wallet from his hand.

However, before she could react, Itachi's body exploded into dozens of crows.

"What the heck, nya!" Kuroka cried in shock and tried to dodge, but instead of attacking her, the crows flew away in the other direction.

As Kuroka and Shirone looked around in confusion, on the rooftop of a nearby building, Itachi, the real Itachi looked at them in interest.

Line Break

"There you are Itachi." Rias said in relief when she saw Itachi walking toward them "Are you alright?" She asked concernedly, looking at him from head to toe.

"I thank you for your concern, Rias-sama, but I'm okay." Itachi said with a smile "Unfortunately, the two thieves got away."

"Ara, it's too bad then." Akeno nodded her head and said in disappointment.

"I'm sorry."

"No no, it's alright." Rias said while shaking her head "They need that money more than me anyway."

"How nice of you for saying that, Rias-sama." Itachi smiled before looking at the sun "It's getting dark, we should go home now."

"Okay."

End of chapter 6

Yagami's note: Done! This is the next chapter of The Devil Sharingan. I hope you all like it.

I finished this chapter in a couple of hours… can't believe that I can actually write a chapter that fast. Hopefully, I don't mess anything up and there're not many grammar errors.

Now, onto this chapter, I hope you like the introduction of Kuroka and Shirone, aka Koneko. I have read some reviews and some PM messages and come to realize that the cannon plot where Kuroka betrayed and killed her master before going stray, leaving Koneko behind and then she was helped by the main character of the crossover fic has been overused.

So, I thought what would happen if tried something different, or why not try to do something different? I believe it's time to play some new, better plot for the two Nekoshou sisters, right?

That is that I would also like to point out a couple of things some of you guys have been mistaken:

First: Itachi cannot have a peerage at this timing! Why?! Because he's still a low-class devil! Only high-class devil is allowed to have their own set of Evil Piece.

Second: You need to absorb the Evil Piece into their body to be officially reborn into someone's servant. So as you can see, Itachi has Serafall's Queen piece OUTSIDE of his body.

Third: While the Pawn has the power to promote into any pieces, from Knight to Rook, to Bishop to Queen… I believe that the Queen piece is the most suited piece for Itachi. Why? Because it's a perfectly balanced piece. It has the trait of Rook, Knight, Bishop and so far the strongest piece. As a Pawn, you can promote to Knight, fast and skill, but you will be weak in physical combat and low on defense, as a Rook, you will be insanely strong in brute strength and defense, but you will be slow and all… think of it like that, and I don't see Itachi having any problem with his fighting style. He has the speed, the skill, the strength and most of all a fucking eyes that can pull the entire combat abilities I mention above (Susanno). While the Pawn has potential, I think the Queen suit Itachi the most.

What truly happened in that garden between Serafall and Itachi will be revealed in the future chapter.

Anyway, that's it and I hope you all enjoy this chapter.

Ja ne!

P/S: I'm still working on the link to the Arcreed's story, but I think you can just Google it anyway.
