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.

[Time skip]

[2 years later]

Itachi closed his eyes before dropping himself down the cliff.

For a young, thirteen years old child, dropping himself down a cliff would be something really extremely, especially when that child was a young devil but didn't intend to use the wings. Instead, the boy made a flick of his wrists and almost instantly, three kunai appeared in his hands between his fingers. Without turning back, Itachi outstretched both of his arms and threw the kunai in various directions, heading to the targets he placed on the ground before using two kunai to slow himself, stabbing them into the steep cliff. When he was twenty feet from the ground, Itachi placed his feet onto the cliff and made a jump, backflipping on midair and threw the kunai he was holding at the nearly invisible wires, cutting them and activating the traps he set up himself. Four platforms shot out from the ground, throwing kunai at him from all directions.

The prodigy Uchiha dodged the first barrage of kunai coming from the front by sidestepping, but caught two of them in midair and threw them at the waves at his left and his right, deflecting them, at the same time took a jump to dodge the kunai that were coming to him from behind, making them fly pass him harmlessly and stab themselves down to the ground.

Itachi made a small smile at what he did. Over the past few years he trained a lot, physically, mentally and magically, even archiving feats that weren't possible for him when he was that age, and Itachi made sure to train them to highest peak of his abilities, surpassing even the higher-class devils twice his age.

Itachi stood up, allowing himself to make a satisfied smile and started gathering his kunai, the handmade Shinobi weapons he made himself with metal he found at Underworld's landfills, using steel instead of chakra metal, because he doubted the world he was living in had something like that. He made a few dozens of them, including many shuriken and the other gears with his own hands, it was tough, but it was nothing he couldn't handle with a couple of Katon Ninjutsu, and many days of skipping school.

Suddenly, Itachi heard a sound and took one of the kunai in his hand before throwing it after turning around. The kunai cut through the air and headed to the target with blinding speed.

"Eh?!"

Luckily for Rias Gremory, Itachi didn't aim for her head but the tree next to her, missing her cheek by mere inches after cutting down some of her hairpieces.

Also, he flew it so fast that she couldn't see it coming, only a gush of wind.

"Rias-sama." Itachi asked, faking a surprise expression with his eyes widened slightly "What are you doing here?" His personal training ground, at least the place he made into his training ground was a small forest located at the Far East of Gremory's Territory, miles away from her house.

"I tracked you and came here looking for you, Itachi." Rias said, pausing for a second before saying "Well actually, Enku helped me tracked you down, he's waiting for me outside the forest." Enku was her brother's [Pawn], who had become Rias' caretaker a year ago when Rias decided that her home wasn't interesting anymore and wanted to go outside, mainly go to Itachi's home to play with him. She probably came to his house first and found that he wasn't there before asking the Kirin to search for him.

Rias was twelve years old then and she had grown more and more beautiful with each year, becoming more and more like her mother who Itachi had a pleasure to meet pretty often. She was a nice and responsible woman.

Something for his observation only: a year ago, Rias had started to develop breasts, showing signs of maturing at a very fast pace. After two years, Itachi found it rather strange for her to have breasts even bigger than some girls four or five years older than her. He didn't know how big they would become when she's fully mature, but Rias, no doubt would become the sexiest girl he had ever met.

Of course to him, a girl wasn't just all about her face and body, but it was hard for him not to admit that.

"Oh, alright." Itachi nodded his head and walked away the rest of the kunai "Please wait a few seconds."

"Let me help you, Itachi." Rias ran toward him and pushed Itachi out of the way to pick up the kunai he was about to pick up before going for the others, picking up with the speed way faster than him with a very bright smile "Is this a weapon?" She asked curiously, looking at the bunch of kunai in her hands.

"Yes, it is… so please, be careful Rias-sama." Rias nodded her head rapidly and went on the gather the rest. With her help, he was able to gather everything in less than thirty seconds and put them away into his dimensional storage with a storing spell.

"What are you doing here out here all alone anyway?" Rias asked as she watched Itachi gathered some very thin, almost invisible wires, something that he preferred to do by himself "Training with knifes and wires?" Rias tilted her head to the side and asked, wondering why Itachi didn't try to try with something cooler, considering that he showed and taught her a lot of cool tricks and was an expert in almost anything.

"They are called Kunai, Rias-sama." Itachi said before smiling at Rias "And yes, I'm out here training. Can't let myself falling behind you, am I?" Rias made a really big smile after that while nodding her head rapidly "So what about you, have you been training your magic lately, Rias-sama?"

"Of course." Rias pushed her chest out and said proudly "Onii-sama said training was very important even for us high-class devils. We shouldn't rely on our power we're born with and should train hard for a higher level." Itachi nodded his head in agreement "I'm proud of my power, but I want to get stronger too." Young high-class pureblood devils like Rias were usually born with extraordinary powers and talents they inherited from their parents, so not many of them wanted to train to become stronger, because they were proud of their power and believed that they were already strong enough.

A perfect example was Raiser Phenex, Rias' fiancés.

"There done." Itachi said and put the wire away with the same spell "We should get out of here, this place is not very safe." Rias nodded her head and followed him. The two of them made their way out of the forest, using the path Itachi made sometime before when he first found the place to avoid, something he preferred more than fighting dangerous animals and even Stray Devils.

"Neh, do you know that today is a big day for me." Rias spoke up, starting a conversation "I'm going to receive my own set of Evil Pieces."

"Oh, it's great to hear, congratulation Rias-sama."Itachi turned his head to her and smiled.

"Thank you." Rias nodded her head gratefully.

"Are you excited?"

"Of course I am!" Rias said with a very excited tone, making Itachi chuckle "I can't wait to start my own peerage, have my own servants, those that are like my family and train a lot to become stronger with them." She said, tightening her hands into fists and made a confident smile "I'm going to have the strongest peerage, and win in each Rating Game match!" It was her dream alongside with the dream of becoming the next Gremory's head, from the day she learnt how exciting a Rating Game match could be.

"I see… then I wish you the best of luck Rias-sama." She had gut and determination and that were everything she needed to accomplish her dream.

"Um…" much to his surprise, Rias started acting in a very strange way, looking away while playing with her own hands rather nervously, as if she wanted to say something to him but didn't have the courage to do so.

"What's wrong, Rias-sama?" Even though Rias was very, very smart for her age, she was always so cheerful, and such a happy child so seeing her like that was the first for Itachi.

"Um… I have been wondering… uh, when I receive the Evil Pieces," Rias turned to him and said with a very fast pace "willyoubecomemyfirstservantItachi?"

"Excuse me, can you say it again?"

"W-will… will you become my first servant Itachi." Rias finally said it, a little bit slower. She then suddenly took a step forward and stopped him, blocking Itachi from continuing walking and cried "I'm so sorry! You don't have to if you don't want… it's just…" Rias looked away while starting to play with her hands again, missing the surprise in Itachi's eyes as he then turned his head to the left as if he just noticed something.

"WATCH OUT!"

Suddenly from the left side of the path, a wild bear larger than an one story house, shot out after shoving the entire line of trees out of the way with its massive body before lunging at them with the speed nearly impossible for something its size, howling angrily at the last moment when it saw Itachi. Rias heard the beastly howl and paled greatly when she saw herself being overshadowed by a massive bear, her body froze in shock and fear, unable to move an inch of her body and could only stare at it.

But before the beast could claw her inside out, Itachi suddenly launched himself forward and thrust his palm into the beast's torso. It might look like a simple palm thrust, but his attack was actually a Juken strike. His palm strike wasn't enough to do any exterior damage to the giant beast, but the chakra he injected into its system was more than enough to cause it great pain.

The beast howled out in pain and stumbled back. It then gave Itachi a hateful glare before retreating into the wood, and disappeared after a few second.

"Are you okay, Rias-sama?" Itachi turned around and asked the crimson haired girl with a concern tone.

"That was…" But the girl only gave him a blank look before crying out in excitement "…SO COOL!" She cried "You beat the bear simply by striking its chest with your palm! How did you do that? Can you teach me that palm strike move?!"

"I don't think it's a good idea, Rias-sama." Itachi shook his head, making Rias pout.

"Mou~, why do you always give me that answer?" Rias crossed her arms on her cheeks "You said you would teach me something more effective when I was older, didn't you?" Rias huffed and looked away "Forget it, unless you teach me that cool trick, I am not going to play with you anymore."

Itachi couldn't stop himself from sighing, but smiled nonetheless. Somehow, Rias reminded him too much about Sasuke when he was younger.

"We should leave, Rias-sama, before that bear…"

"I won't move until you show me how to do it." He was expecting something like that, so he wasn't surprised.

"Rias-sama…" Itachi raised his hand and beckoned her to come over, which she did with a large smile on her face. However, as soon as she w as close enough, Itachi poked her on her forehead, an action that he had been doing constantly for the past few years.

"Eh!" Rias groaned in disappointment, because she knew what was about to come next.

"I'm so sorry, Rias-sama." Itachi chuckled "Maybe next time."

"Why must there always be a next time?" Rias pouted with her cheeks puffed out "Is there no next time?"

"There is, Rias-sama… but when that time comes… well…" Itachi shrugged and turned around to walk away "Let's go Rias-san, we should hurry before Enku-san get worried for your safety."

"Hey, answer my question properly Itachi!" Rias shouted and ran after him.

Line Break

"So, Itachi…" Rias said excitedly and extended her arm, pointing at the bookshelf behind her "what do you think about my newest collection?" Itachi couldn't stop himself from sweat dropping at the amount of manga, anime DVDs, and action figures she had on her bookshelf.

"It's very impressive, Rias-sama." It was the only thing he could come up with at the moment. Itachi knew that Rias was an Otaku, and she was also one of the biggest Japan's fans he had ever encountered. She also had a huge collection of Japan's objects and artifacts in her room, which she collected over the years.

"Mou~, what with that expression!?" Rias glared at him with half-lifted eyes, pouting cutely "You're supposed to say… It's great, Rias-sama! I like it a lot! How did you collect them all in such a short time? Or something like that, you know."

"Um, alright then, I will make sure to remember that." Itachi nodded his head.

"Anyway, I will let you pass for now." Rias pointed her hand at him before saying "Because today, Sona is going to come over to play with me, and I'm going to introduce you to her."

"Sona?" Itachi asked curiously.

"Ah! Don't get the wrong idea!" shouted Rias, making Itachi look at her in confusion. He didn't know why she suddenly shouted like that "Sona is just a childhood friend! And a girl too! There's no way that I have a romantic feeling for her!" Rias continued shouting her denial, which made him stare at her flatly.

"I've never speculated anything like that…." Itachi stated, causing a dumbfounded expression to appear on Rias' face.

"…Eh?" Rias' face slowly turned bead red from embarrassment. She turned around and covered her face as she was too embarrassed to see Itachi in the eyes.

"…" Itachi sweat-dropped as he continued to stare flatly at Rias, who looked away while scratching the back of her head in embarrassment "Rias-sama, look at me for a sec," Itachi said to the little lady of Gremory, and she did exactly what he wanted.

POKE

Itachi used that opening to thrust his fingers to Rias' forehead.

"Auhhh!" Rias fell butt-first to the ground, but she quickly recovered and leaped at him the next moment. "Muuuu! Itachi, you meanie!" Rias yelled as she pounded at his chest. Itachi fell on his back, but it didn't hurt at all.

"Sorry. You looked so adorable, so I just…" Itachi teasingly said.

"A-adorable?! Steams rose from Rias' ears as her face turned red. Itachi inwardly sighed when Rias turned around and began acting all shy.

After he had stood up, Itachi said "Anyway Rias-sama, I know who Sona Sitri is." Itachi said "Kaa-sama told me that she usually came to play with you."

"Yeah, she's my best friend at school, but she's also my rival in a way." The crimson heiress pointed out before poking him in the chest, the same way he usually poked her forehead "This is also a great opportunity for you to get to know some high-class devils other than me, but remember that only we Gremory are known for our affection to servants, the others might not treat you like us." He had never met a Sitri before, but that was something he could agree on "So don't get too familiar and friendly with her, got that?"

"I will." Itachi nodded. Though, he couldn't help but feel that there was a hidden or some sort meaning behind Rias' speech.

Eventually, Sona Sitri arrived and was waiting for them in the living room. Itachi and Rias stood still in front of a large door, the later was fidgeting with excitement as she was finally able to see one of her few friends and rival again.

Itachi, who stood behind Rias, was deep in thought. He was wondering what Sona Sitri was going to be like. He hadn't met that many high-class devils, only Rias, her parents and on occasionally, her brother who came to Gremory Residence to visit her. The last high-class devil turned out to be exactly what he imagined sinful devils to be, and he was none other than Raiser Phenex.

All of those thoughts were instantly washed away the moment Rias opened the door and a certain mahou shoujou's voice came from the room.

"Muuuu~, So-tan~, stop sulking~," came the whining of a woman that he knew very well who the owner was. The moment he heard this voice, he froze. He was not proud of it, but he knew who the owner of that bubbly voice was.

"I am not sulking, Onee-sama. I'm simply upset that you did not even consider changing your attire," the so-called So-tan, who Itachi believed to be Sona Sitri, stated. There was an edge in her voice that would make even adults shuddered, but the mahou shoujou was unaffected in any way.

"But, this outfit is so cute~. It's a sin not to wear it~," the mahou shoujo, who was none other than the girl he met a couple of years ago, Levia-tan, explained cutely.

So-tan stared at her skeptically. "A devil talking about sin…Onee-sama, if you wear that silly outfit, don't you think you would taint its purity instead?" she mockingly asked.

Serafall pouted, and pointed a finger at So-tan. "Mou~! Sona-chan meanie~! Just admit that you want to wear this too!" Serafall declared.

Sona almost fell from her chair "I-I don't want to wear that kind of outfit, Onee-sama!" Sona angrily shouted with a red face.

Rias, who heard the conversations couldn't help giggling.

Itachi, meanwhile, couldn't stop himself from wondering how he could be so stupid.

Levia-tan… sounded pretty similar to Leviathan.

As in… Serafall Leviathan.

Slowly, the door to the living room opened and at that moment.

"Ah." Serafall Leviathan let out a surprised gasp as her gaze fell on Itachi "AAAAAAAAAAAHHHHHHHH!" Serafall's scream echoed throughout the castle "It's… IT-TAAAAANNNN~!" Serafall cheerfully screamed as she launched herself towards Itachi.

However, even before Serafall turned herself into a human rocket, Itachi had already fully prepared. The result was that he was able to move a second sooner than Serafall and managed to dodge her right before impact, which, as a result, Serafall hit the floor face-first. As if that wasn't painful enough for the magical girl, due to the speed of her launch, she continued to slide with her face and front body until she hit the wall.

Itachi couldn't stop himself from cringing at the sound of impact.

"That's going to hurt…" Itachi muttered before adding "a lot."

Rias and Sona, on the other hand, were staring blankly at Serafall as they tried to process what had just occurred. Serafall lied on the ground and slowly raised her head to look at Itachi. Itachi started getting a little worry, because Serafall had a nosebleed and was on the verge of crying.

"Hey, are you alright." Itachi walked to her and crouched down to her level, asking with concern "Serafall Leviathan-sama?"

Line Break

"So…" Sona began.

"So?" Itachi repeated. He was standing on a tall chair behind Serafall, who was sitting on the sofa, while wrapping the bandage around Serafall's head. He couldn't help but wonder how someone as powerful as her could get injured that easily.

"Will you forgive Onee-sama's rudeness?" Sona asked as she was trying to comprehend the situation.

"Te-hee ~!" said sister only stuck out her tongue while lightly hitting her head.

After Serafall's failed assault, Fiona, his mother arrived to help them cleaned up the mess, and summoned a box of medical kit to tend the injured magical girl.

However, none of them could have expected that, the moment Serafall stood up she would instantly cling to Itachi, earning him Rias' glare and Sona's apologetic bows.

After she was done, Fiona left excused herself as she didn't want to disturb them. Itachi could swear, though, that he saw his mother desperately holding back a chuckle as she walked away.

"It's not that much of a problem…" Itachi assured with a shake of his head.

"Ehehe~, it's really It-tan~," Serafall cheerfully sang.

Sona bowed her head again. "I am really sorry for her behavior."

Looking at how her younger sister was so adamant in branding her as a problem maker, Serafall playfully tapped Sona's shoulder. "So-tan~, he did say that it's not a problem, so of course everything's fine, right It-tan?" asked Serafall looked up and said to him with a very cute smile that would make most men faltered.

However, Itachi was not most men. And so, he did the only sensible action in this insensible situation.

"Please keep your head straight Serafall-sama." He said and put both hands on her head, repositioning it back so he could continue.

"Nee, It-tan~," Serafall called out to Itachi again as she noticed she was being ignored.

"In case you forgot, which you probably didn't, my name is Itachi Uchida, Serafall-sama" Itachi reminded her "I don't recall my name being It-tan, or anything close to that.

"So is it alright for me to call you, Itachi-chan." She asked.

"I think it's alright enough." He had been called worse. Itachi finished bandaged her head, and then used a towel to clean the blood on her forehead. Serafall smiled and started humping happily as the young boy gently wiped the blood away from her cheeks.

"Itachi…" Rias spoke up, earning his attention "You seem to be awfully close with Serafall-sama." She fiercely accused.

Before he could say anything, Serafall jumped in and asked it

"What's this~? Is Rias-chan jealous by any chance?" Serafall teased with a sly giggle.

"I-!" Rias tried to say something, but her lips instantly closed into a very thin line and her face turned red.

"Really now, Rias. To be jealous of Onee-sama, of all people?" Sona asked, her voice was thick with mockery.

"Ah! So-tan! What do you mean by that?!" protested Serafall.

"It's what you heard," Sona replied truthfully. Sona turned her attention back to Rias. "So my self-proclaimed 'rival' is this fragile… Why don't you go to Sirzechs-sama and have him pamper you again? Who knows, maybe this time you would come back a bit more mature?" Sona asked sarcastically.

"Sona!" Rias stood up and glared fiercely at her rival and friend.

"There done." Itachi finished and smiled "Give it a few days, or a more proper treatment and you'll be fine Serafall-sama." He jumped down from the chair and put the residual bandages into the medical box.

"Ah… you're so great at this Itachi-chan." Serafall said, putting a hand on her bandaged head "I really hope that that I have a servant like you."

"Onee-sama, can I have a few words with you please?" Sona spoke up and folded her arms together on her chest, pulling her sister toward a far corner of the room and started lecturing her.

"Itachi," Rias called as she approached him and got into what people would dub as lecturing pose "I know boys always want to satisfy their carnal desire, but don't let it control you."

Itachi sweat dropped. 'Where in the world did she learn this terminology?' Itachi wondered. He knew devils had higher learning capacity than humans, and also daily sexual contents weren't something unnatural for them. But to see someone as young as Rias, a devil yes, but a young girl no less, lecturing him about carnal desire, it was actually the first he had ever seen.

He was brought out of his musing, because Rias' face was right in front of him.

"Well? Do you understand?"

He replied "Yes, ma'am."

Looking satisfied, Rias went to Sona, finally giving Itachi a chance to take a breather before following after her.

"So...Serafall-san...and you must be Sona Sitri-sama, am I correct?" Itachi asked, halting the sisters' argument.

"Ah, yes, I am," Sona replied. Her face then turned red from embarrassment and she coughed once before standing right in front of Itachi. "I noticed I have not yet formally introduced myself. My name is Sona Sitri, the second daughter and heir to the Sitri clan. It is a pleasure to meet you," Sona said, introducing herself with much mature mannerism than a child of her age should have.

She extended a hand for a handshake to him, and Itachi looked at it for a moment before taking it.

"The pleasure is all mine, Sona-sama." Status was really important, so Itachi said with a respectful tone "My name is Uchida Itachi. I'm just a son of a maid and a chef of this family." Itachi said.

"The maid with blonde hair who walked into this room?" Itachi nodded at Sona's question. Good, she didn't question what Rias was doing with a low class devil like him, which was more than enough for him to know that she was very similar to Rias, in a way and wasn't the usual stereotype spoiled devil brats.

"You can also call me a lifelong babysitter for Rias-sama." Itachi joked a little, causing Sona to almost snort.

"Ah! Itachi! What do you mean a 'babysitter'?" Rias asked, visibly offended.

"That just mean you haven't and probably will never change," Sona teased.

"Guguguuu..." Rias gritted her teeth and then declared, "Just you wait! I'll become a first-class lady, and I'll have you take back your words when that day comes!"

"Sure. If that day comes, alright?" Sona teased further with a devious smile on her face.

"Kuu..!"

Before Rias could retort, Serafall cheerfully jumped between them. And then...she twirled before giving them a 'v' with her tongue sticking out.

"Okay~, now it's magical Levia-tan's turn to introduce herself~," Serafall sang. However, the sole man in the room instantly shot down the 'excitement'.

"We already know who you are, Serafall-sama."

"Boo~, Itachi-chan you killjoy," Serafall giggled while pointing her thumb down.

After Serafall reintroduced herself to Itachi again, using the same magical girl's introduction, they had relocated themselves to the garden where a small tea party had been prepared for them by the maids of the house. With a Maou's permission, even a servant like him was allowed to sit with them around the table. There were teas and cakes on the round table in front of them, yet none of them had their attention on any of them.

They were instead focusing their sights upon a chessboard, and the duel between Rias and Sona. Itachi was currently watching at the sight, with an interested smile on his face.

Rias glanced at his rook, but then he moved his bishop instead to make it in line with Sona's king. As expected, Sona's queen took his bishop.

"A reckless move. Do you think I would let you check me so easily?" Sona asked while playing with Rias' bishop with her fingers. Rias pouted and tried to move her Knight, but Itachi grabbed her hand and moved it to her E-4 Pawn instead.

"Move this one to this position, Rias-sama." Itachi said, pointing his hand to F-6. All eyes turned to look at him, especially Sona.

"Eh?" Rias was surprised "but, it's a weak piece… also, she would…"

"Just do it." He pressed, his eyes were looking at the chessboard.

"Okay then." Rias grabbed her pawn and moved her Pawn from E-4 to F-6. Her eyes then widened in shock and smirked when she finally realized it.

Sona sighed in disappointment, and she moved her knight to avoid it being taken by Itachi's pawn, however, that proved to be a huge mistake.

"As if it could…" but her eyes widened in shock when

"Fool..." Rias smirked widely and moved her Rook to take Sona's knight "Thank you, Itachi!" she smiled at him and gave him a thumb up.

"I expect you to learn something from this, Rias-sama." Itachi smiled "Pawn is a weak piece, yes, but you know how to play them right, they can be just as deadly as the Queen."

"You mean promotion?"

"It's something like that, but yeah, you understand."

"Tch…" Sona scolded while trying to come up with a new strategy. After ten seconds of thinking, she moved her Queen three steps forward.

"What are you trying to do Sona?" smirked Rias and reached her hand out for her Bishop "Scarifying your Queen for me?" she had the opportunity to take out Sona's strongest piece, and she wasn't going to miss it.

"Hold it." Itachi raised his hand again "You move your Bishop to this position." Rias looked at him in confusion, but did what she was told. Sona pushed her Queen forward "Then move your Knight to this position." That move completely blocked Sona's Queen's path, and she had no choice but to move her Pawn instead "Then you move your Rook to this point." Sona widened her eyes at the formation "Then your Queen to this point." Itachi muttered something under his breath before saying "And last, you move your Knight here." Rias did it and widened her eyes in shock.

"Checkmate!" She declared. Both Sona and Serafall widened their eyes and dropped their jaw in shock "Y-you're so… smart Itachi." She admitted it out loud. She had always known that Itachi was smart, but she didn't know he was smart enough to turn the table around for her and beat Sona, who had never lost a single chess game before, even against someone twice her age.

"Y-you…" Sona pointed at Itachi while stuttering. She then stood up and slammed her hand down to the table, with so much force that the pieces made a jump and the cups of tea nearly fell over "That's it, if you think you're so smart, then have a match with me!"

"Hey, don't talk to Itachi like that." Rias scolded, glaring at Sona.

"I don't think…"

"I challenge you Itachi Uchida!" she challenged him

"Hey, I think it's a great idea too." Serafall suddenly said in excitement "Between the two of you, who's smarter?" she asked, looking at them both "Now I know that Itachi-chan is smart enough to provide a decent challenge for you, So-tan. I have never seen Sona losing like that before, so why don't you two play a chess game to see who's smarter?"

"It's a Maou's wish." Sona growled "Why are you going to do, Itachi-san?"

"Then I accept your challenge, Sona-sama." Itachi accepted her challenge calmly and rearranged the pieces 'Young and proud... If she was born a man, it's no doubt that she'd be like Sasuke, minus the part I turned him into.' Itachi mused and said "I will take the black."

"Are you giving me the upper hand?" Sona asked, sitting down her chair.

"With all respect, Sona-sama, no." Itachi shook his head.

"Since it lacked tension, the winner of this match will receive a special hug from magical Levia-tan and Rias-chan~." Both Itachi and Sona froze. Rias, on the other hand, was looking at Serafall with confusion.

Sona mustered her courage, despite fear of knowing the answer, and asked, "And…what will happen to the loser?"

"Will get a double kiss on the face from us~," Serafall casually answered. It was understandable why Rias instantly panicking while looking at Itachi back and forth with a really red face.

"..."

"..."

The two of them remained speechless. Itachi sighed while shaking his head, his day turned out to be a little more eventful than he thought.

Sona, however, quickly made her decision.

"Let's begin." After she declared that, Sona moved her Pawn "I'm going to put it my all in this battle."

"You don't have to take it so serious like that, Sona-sama." Itachi instantly reacted by moving his knight "This is my first time playing chest, actually."

"Excuse me?" Sona moved her pawn.

"I only play Shogi on the internet, but it's pretty similar to Chess." Itachi shrugged his shoulder.

"Shogi? Isn't that Japanese's chess?" Rias asked in surprise, also excitement.

"The General's game." Sona nodded her head and moved her first bishop.

After ten minutes of playing, Itachi looked at the position of the chess pieces, and inwardly smiled. He was impressed. Sona's perception and wit was the highest he had ever seen from a child of her age.

Give her twenty more years with a proper education, and he had no doubt she could match, or even exceed, Shikaku of Nara clan.

Yet, there was something that she lacked as of now to be able to utilize her brain to its fullest, which was none other than experience.

For that reason, she did not realize that she was being led to a certain conclusion by Itachi. Smirking victoriously, Sona looked at Itachi.

"You've done well, but with this," she moved her queen and was about to put it down next to his king "it's a check..." she stopped, because it was the moment she realized she couldn't do that.

But she had to, because she had already picked her piece up

"That was a splendid game, Sona-sama." Itachi said, bowing "Thank you very much, I've learned a lot of valuable lessons from it, but this is my win." Itachi used his rook and removed the white King from the gain, taking his win "Distraction. It's a trap I set up to make you drop your guard for the sake of winning." He pointed out "However, if this were an actual battle, you would have the opportunity to wipe out the entire army, even if you lost your King. It's my luck that this is a chest game, where the game will be ended as soon as a king is removed from the game." He said in a serious tone. Serafall looked at the young black haired boy in shock. She wasn't expecting such words for someone his age. Not only had he proved to be smarter than her sister, but also a whole lot smarter and wiser than she thought.

"A-amazing…" Sona muttered before signing "This is my defeat." Sona admitted her defeat.

"You're so amazing Itachi!" Rias smiled widely "You defeated Sona!"

"As if you could do the same thing, without his help, of course." Sona turned to look at Rias, who gritted her teeth in frustration.

"Itachi…"

The reincarnated Uchiha turned his head to look at Serafall with his eyes widen in surprise.

She called his name without using the suffix '-chan' or '-tan'

"Are you taken?" Itachi just tilted his head to the side in confusion "I mean, you're not in any peerage, aren't you?" he nodded his head "Well then, do you want to become my servant." Both Rias and Sona dropped their mouth to the ground in shock, especially the crimson heiress "I have some spare pieces right here." She pulled out some blue, crystal chess pieces from her pocket and put them on the table "You have the potential for greatness, Itachi. Come with me and live for me, I will make sure to help you reach your fullest potential, and more." She said with a smile. It wasn't a cute and playful smile, but a smile of a true leader, worthy of her Maou title "What do you say?"

"W-wait Serafall-sama." Rias jumped in "I wanted to make Itachi's my servant as soon as I receive my set of Evil Pieces, you can't do that."

"Rias-chan…" She then glanced at Rias, giving her a small smirk "Are you trying to defy a Maou's wish?"

"I… I…" Rias was put in a tight situation, and didn't know what else to say and could only hang her head low in defeat.

"Aw, don't be so sad, I'm not going to take him anywhere, or away from you." Serafall smiled, hugging Rias who was at the verge of crying.

Itachi was also speechless, as he had never expected something like that. Itachi knew, that sooner or later someone would notice his potential as a powerful servant for them, and would come to ask him to become their servant in exchange for a chance for a higher status and many things along those lines, something a low-class devil like him could only dream about.

But he would never expect someone like Serafall Leviathan, a Maou, to ask him to become her servant.

He had no problem with the fact that he had to become someone servant in the near future, since from the moment he was reborn and born as Itachi Uchida, he was destined to become a servant of high-class devils. Like his mother and father, who became a maid and the head chef for Gremory Household.

It was harsh, but Itachi understood that in the society of devil, low class devils like him would never get the chance to speak their voice. The only reason why his family was able to live happily, poor but happy, was because they were serving the Gremory.

It's only a matter of what kind of servant he was going to be.

"So, what are you going to say Itachi-chan?" Serafall winked at him "It's a Maou's wish. Of course, it's free for you to decide, but you should know that there's always a spare piece in my peerage for you."

Itachi had finally made up his mind.

"I…"

End of chapter 4

Yagami's note: BANG! In celebration of my two year anniversary as an author of , I have decided to restart this little piece of art every love so much!

My deepest apology for the delay, mainly because the lack of inspiration as well as the drop of review (just kidding). A couple of days after I published the third chapter, I decided to wait a couple more days in order to get more reviews before updating, but… well, as you can see, the third chapter have the lowest amount of reviews so far so…

Anyway, I hope you enjoy this chapter. You can call me evil for leaving it as a cliffhanger like that, but you have to wait till the next chapter to see Itachi's final decision for Serafall's offer. Of course, since he's already a pure-blood, but low class devil in this story, there's no point of turning into a devil to have a huge boost in power, but by becoming Serafall's servant, opportunities will be opened for him and for me to write as well.

I have already made my decision, but I will still call for a vote. Leave a comment in the review, tell me your thought about this! Should Itachi become Serafall's servant?! If he did, what piece should be become?!

Hope you like the interactions between Itachi and the girls. They're still young, so I can only write the hints at that point.

Young Akeno will debuted in the next chapter, so stay tune for it.
