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 taken 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 3

[Time skip]-[Six years later]

"Itachi-kun, play with me!" Said a ten year old, incredibly cheerful and happy Rias Gremory as she stood behind Itachi, the boy she claimed to be her best friend, with a lot of toys in her arms.

"Alright then, Rias-sama…" Itachi nodded his head and closed the book he was reading, standing up from the bench he was sitting on and turned around to face Rias, who then smiled brightly and dropped down to her knees on the lush grass of Gremory Residence's garden "How's your day, Rias-sama?" Itachi asked with a small smile as he sat down in front of Rias and picked up one of her toys, an action figure of an anime series.

"School is boring~…" Rias moaned loudly "They taught things I already know… and Raiser is trying to be mean to me again." Like all young devils with high status, Rias got tutored at home from the age of four and since the girl was quite a genius herself, it didn't take Rias long to memorize anything that she was taught, making school really easy for her. However, she still went to school just like any children when she's ten year old. It was a school for rich kids like her, with better quality than the school Itachi went to but that was beside the point.

Ever since Itachi saved Rias from Raiser Phenex and his minions and showed Rias something that could get a child her age really excited, she had taken a liking to him and demanded Itachi to come to her home every time he's free to play with her. When he refused, because he would like to stay at home during that time to read books and train, she turned to her parents, who she asked to hire him as her friend for real and then to his parents, who were asked to bring Itachi to her home so the two of them could play. The parents agreed right away, with the Lord and Lady of Gremory Household thought that it might be a good thing if their daughter had a friend who didn't come from high-status household, not to mention that he's also the son of their most trusted servants (Fiona's Venelana Gremory's personal maid, while Ichirou's Zeoticus Gremory's favorite chef, who taught him many useful tips in cooking). Itachi's parents thought the same and believed that Itachi should have more friends than none at all, since their son kept his attention in books. Plus, it was Rias Gremory, they were talking about. She was the beloved daughter of their lord and lady, any servants would love to have an opportunity like that.

He didn't get much chance to play with Sasuke when he was young, but he did know how to entertain a ten year old child like Rias. He also spent his time at Gremory Residence to explain to Rias anything that she couldn't understand, from the random everyday things to the things her tutor and school taught her. In a way, it's like she had become his little sister, and he cared for her like a big brother. However, dealing with her was completely different than dealing with Sasuke and his childish behavior, it took a lot from him just to keep the usual energetic crimson haired princess from becoming overexcited sometime.

"I see… did he do anything to you?" Raiser was seven years older than Rias, so he was twelve year old then. Even though he had Rias as his fiancés, that douche made quite a reputation for being a playboy at school, even Itachi knew about it from the girls of his class when they gossiped to each other about the third son of Phenex Household. Overall, from what he heard from Rias, her fiancés viewed her nothing more than a cute face, and the only reason for him to pay any attention to Rias was because he thought she was going to grow up into an extremely busty woman. For someone who lived in fairy tales about growing up and marrying a knight in shining armor like Rias, it could be quite annoyed and frustrated, and she had come to hate Raiser from the moment the two of them met, and their marriage engagement was declared.

"Of course," Rias pouted but then smiled brightly, making a twisting movement with her hands "But when he tried to grab me, I did that super cool trick you taught me and threw Raiser onto the ground. His face was absolutely priceless."

"I see…" Itachi smiled and nodded his head "Good to know then Rias-sama." It was just a simple move Itachi taught Rias to defend herself, since in his opinion no matter what age they were, girls must know how to protect themselves.

"Itachi, can you teach me something else?" Rias asked, her eyes sparkled with excitement "I want to kick Raiser's butt every time he tried to approach me."

"I don't think it's a good idea Rias-sama." Itachi shook her head, making Rias pout "Your parent won't be happy when they learn that I'm showing you dangerous thing. You don't want them to drive me away, do you?" Rias shook her head immediately "Let's just stick with that wrist twisting move for now, when you're older I will teach you something more effective."

"Like the rock throwing trick?"

"Like the rock throwing trick." Itachi repeated, but it was not a question.

"Yay!" Rias threw her hands into the air and cheered before reaching into her toys and pulled out a box of Lego "Also, I bought this yesterday, how about we build a house together?" Rias asked and poured the tiny pieces of Lego out of the box.

"Behind you, Rias-sama." Itachi said and picked up a few pieces. The two of them worked rather quick, because in only five minutes the first two floors was finished. The game they were playing was pretty famous amount the young devils of the Underworld, because the box could provide a nearly endless supply of Lego pieces for them to build anything they wanted, as long as they were recorded in the pieces' memory, because one single piece that was out of place or different that the original, the entire structure would fall into pieces and they would have to do it all over again. It was a pretty complicated game for children Rias' age, but she handled it rather well since they had decided to build Lilith Castle, her brother's palace at Lilith, the capital of Underworld.

"There done." Itachi nodded his head and smiled when he put the last piece onto the highest tower "Good work Rias-sama." He got off the castle and jumped down to the ground. The model itself was bigger than the two of them put together, and with Itachi's meticulously hand, it's also extremely detailed.

"Yay!" the girl cheered.

"Rias-ojou sama," They both looked up and saw Fiona, Itachi's mother, wearing the black, white and crimson uniform for maids of Gremory Household, bowing her head to Rias before turning to Itachi "Itachi-kun." She smiled at her son.

"Hey Kaa-sama." Itachi smiled back at her.

"Look look, Fiona… we built this together." The crimson heiress said while pointing both of her hands to the castle, jumping up and down excitedly "It's beautiful and great, right? right?"

"Yes Ojou-sama, it's very beautiful" Fiona smiled at the girl before saying "Anyway, ojou-sama, I'm here to tell you that your tutor has arrived and it's time for you to study."

"Eh?" Rias whined "But I want to play with Itachi more, can you skip it for me just today please?" Rias asked with a smile, putting both of her hands together.

"I'm sorry Ojou-sama, but I can't…" Rias huffed and turned her head away, refusing to leave. Fiona sighed and turned to her son for help, because the little mistress of Gremory Household could be really stubborn sometime.

"Rias-sama, you should go." Itachi decided to speak up "It's not wise to skip your lesson."

"But I want to play with you more…" Rias whined, refusing to leave, since she was having so much fun with her new friends. The crimson haired girl then got a brilliant idea, as she grinned at Itachi "How about Itachi join me to? I'm sure that miss Jenna won't mind."

"But I have school in a few hours, Rias-sama." Rias pouted, with her cheeks puffed up cutely and crossed her arms on her chest "Sigh…" the girl could be quite stubborn sometime, reminded Itachi of Sasuke when he was young, nonetheless "Rias-sama." Itachi raised his hand, and the moment Rias turned her head back to him, he poked her on her forehead, much to her surprise "I'm sorry, but let leave this for now… next time, alright?"

"Mou~… stop poking me, Itachi. It isn't fun at all." Rias whined, holding her head with her hand but nodded nonetheless, with a smile because she got something to look forward to. "Next time." And she followed Fiona into the house, after waving goodbye to the black haired boy, who disappeared into a puff of smoke shortly after.

Line Break

Itachi, the real Itachi, meanwhile was exploring one of the many ancient cities of the Underworld, Lilith, also known as its capital. It wasn't very far away from Gremory Castle, but much, much more crowd than his home city. Lucifaad was the original capital of the Underworld, though the new Maou made the central city of the Underworld their new capital and Sirzechs Lucifer moved there with his servants, naming it after the mother of all devils Lilith herself, who passed away a long, long time ago.

"A box of five dango, please." Itachi said to the shopkeeper of the dango stand and gave him the money 'It seems my clone has disappeared' Itachi thought as he received the memories of his clone who he sent to play with Rias. Not that he didn't want to play with her, but Itachi believed that he got more important things to do and a clone in his place should be enough to keep Rias company "Thank you." The eleven year old boy smiled and accepted the box of dango before continuing walking.

Wandering around the cities of the Underworld with a box of dango in his hand like that had become one of Itachi's many hobbies ever since he came to the Earth. Itachi loved to learn new things, because the devil was a rather interesting specie, and they also had a very strange way of living, with magic and a duty called Devil-job, which was basically an act of granting their clients', most of the times they were human but in some occasion some other species could also wish for the service of the devil, wishes through contracting. It's still too soon for him to think about working, but devil-jobs reminded him of Shinobi Missions and requests. In the past, devils took the souls of their clients at payment, but currently with the Yondai Maou's new ways of governing, they took rewards and money instead.

The other reason was because no one recognized him. As Itachi Uchida, he was just their ordinary and everyday devils, with or without the memories and mindset of an adult, who came from another world.

"Hm?" Munching on his most favorite foods, Itachi looked on in interest at the sight before him. There was a crowd in front of him, as many devils, young or old, male or female, was gathering together to watch something, sometime cheering out loudly in excitement. There were also many flashes of light, so maybe it was a celebrity coming into the city. Curiosity took the better of him, and since Itachi was on a sightseeing trip, he approached the crowd and pushed his way through it to get to the front line, and immediately widened his eyes at what he saw.

Panty… pure white panty.

It was like the Universe just slapped him right in the face.

"What the…" Itachi wondered out loud at he looked the person, or devil or rather a female devil that was drawing all the attention from the other to her, and clearly from the expression she was showing, she was enjoying it a lot. She was a very beautiful teenager girl with long, black hair that was tied into twin tails and blue eyes. She was wearing a pink outfit, or rather a costume of what Itachi could only call a witch costume, or in that case a magical girl outfit, pink in color and exploring much of her belly, and a magical wand with a big yellow star on the head.

But other than flashing her panty around so casually like that, the most ridiculous thing about her, was that while she had a child-like body, as she was only ten or so inches taller than him, she got the largest pair of breasts Itachi had ever seen on someone her age, something that went with her child-like body, look even bigger than usual. They were jiggling, bouncing, and swaying around as she moved her body in various poses, becoming the one thing that was drawing the most attention from the citizen.

"Weirdo…" was the only thing Itachi said before turning around and walked away, thinking that there was a chance there was much of the city for him to see. Though, for some reason that girl looked oddly familiar.

But his word and his action, which was completely opposite from the rest of the crowd, didn't go unnoticed by the magical girl, who was none other than Serafall Leviathan herself.

"Eh…?" was the first word she let out when Serafall saw him walk away and because of his uninterested action, not to mention his hair style that was rather long for a boy, in one second she almost mistook him with her beloved baby sister. "Hey, wait up… the boy over there!" Serafall called out, but with so many people around her, her words couldn't reach him. So Serafall decided to give her fans some last sexy poses before waving her hand to them, saying with her usual cheerful tone "Thank you everyone, for such a great time… but it's time for Levia-tan to go." The crowd all groaned in disappointment, but parted away.

As soon as the path was close, she chased after the boy, who wasn't very far away from her and was walking inside a park. It took her less than five seconds to come close to him and reached her hand out to grab him.

"Hey, wait up!" Feeling something that was approaching him with great speed and called out for him in a feminine tone, Itachi side-stepped and grabbed that girl's hand with one hand and twisted their wrist hard, intending to use their momentum to throw them to the ground. But much to his surprise, the girl stood still like nothing happen, her wrist wasn't bended like Itachi expected

"Eh?"

"Eh?" They proclaimed almost at the same time "Hi?" Serafall said cheerily and waved at him with her hand. From up close, the boy really looked a lot like her sister, even the calm and collected expression he was having, with the only difference being their eyes color.

"Who are you?" Itachi immediately let go off her hand and asked, recognizing the girl from before. Serafall widened her eyes after hearing that question. Sure, most children his age couldn't recognize the current Maou Leviathan, because she wasn't in her real form that was recorded in history book, but they WOULD definitely recognize her from her own TV-show. Being the Maou of Foreign Affairs and a skilled actress herself, Serafall had developed a skill of detecting lies and acts, but from what she could see, he wasn't lying at all.

"You want to know my name?" Serafall then winked at him, with a cute smile before jumping back, spinning along the way "With the power of the stars…" Her skirt spun with her, and once again revealed her panty to the world to see "I will eliminate the evils" She then spun the staff around before leaning back, making a peace sigh while winking "Cause I'm Miracle Levia-tan!"

"Levia… tan?" Itachi asked and Serafall nodded her head, making a hopeful smile. Levia-tan? Rias mentioned about that TV-show before, suppose to be an extremely popular TV-show for children, but most of the fans were adult because of the attractive female protagonist. Itachi finally understood why "Well, good to meet you then. I'm Itachi Uchida." Itachi declared, making Serafall face palmed.

"Neh neh?! You don't recognize me at all, do you?" Serafall asked in shock as she stood up and looked at him.

"You look somewhat familiar, but I can't recall meeting you anywhere." Itachi shook his head at her "Are you a celebrity, or a movie star?" he asked

"I'm both." Serafall winked "You can call me Levia-tan, from now on."

"Oh okay."

"Mou~, what with that expression?" Serafall pouted with both of her fists put together under her chin, jumping around Itachi "You're so much like So-tan, It-chan… the calmness, the cold words for me, even the mature look." she said, but when he thought she was annoyed because of the similarities between him and this 'So-tan', he was surprise to see that she was excited "You're like a male version of her… so cute~" she giggled.

'What am I doing here?' Itachi sweat dropped, and decided to end their conversation "Um… Levia-san, if you don't mind, I think I will take my leave for now. I'd like to go home so I can go to school, if you don't mind." Though, he intended to use a clone to take care of that for him, but that could work as an excuse too.

"Eh~?" Serafall's smile dropped in disappointment "But I want to talk to you more~, maybe spend some more times with you too~. I like you, It-chan." She tried to hug him, but Itachi picked up the dango stick and poke her in the hand, making Serafall take her hand back in surprise.

"Please Levia-san, fan or not, it's not wise to show such affection to a stranger." Itachi told her "And also, please call me Itachi." However, she was still wearing the same disappointed, but childish expression on her face, the kind of smile Itachi had seen so many times from Rias Gremory. He then looked at his dango box, and realized that there was still one stick of dango left.

"Hm?" Serafall looked up when Itachi showed the dango stick to him "For me?" She pointed at herself, with a bright smile. Itachi nodded his head, and Serafall immediately took it from his hand "Thank you."

"That will cheer you up." Itachi smiled before throwing the box into a trash can five feet away from them, and behind his back much to Serafall's surprise "I will see you later, Levia-san." With that, Itachi walked away before summoning his wings and took off to the sky.

What a strange boy, Serafall couldn't help but think about him like that as she watched him disappear from view while eating the dango he gave her.

End of Chapter 3

Yagami's note: My deepest apology for the short update (I believe I can say that this is merely a filter chapter) and after such a long time too… but I hope you enjoy this chapter nonetheless.

School projects has appeared once again, and I cannot put all my time into serious stories like this much often than usual. Lemon can be updated faster, because I don't need to be serious with the plot wise and thought too deep about how the story should play out. So, from now to the end of the next month, I will update this story every Sunday to Monday… that's mean two or three chapter till the end of May.

With the amount of story I'm handling, I believe that I will come up with an update schedule too, balance my time out and at the same time aren't slack off at school.

So, from Sunday to Monday there will be an update for this story.
