(Fem!Harry) Persephone X Byakuran

The first time Persephone Potter met Byakuran wasn't by bumping into him on some random street, but through their dreams. She'd been six at the time when she had her first dream about the pinkish purple eyed albino boy with the odd purple tattoo under his eye. The dream had been the first one in her long life that hadn't been nightmarish in quality and she'd woken with the promise to see him the next time she dreamed. By the end of the day, she was convinced that the boy was just a figment of her imagination due to needing a friend. However, Byakuran was fairly sure he was real and that she was the dream instead.

Persephone looked at the albino boy with a glare, "I am too real, you're the dream!"

"No, you're the dream," The boy shot back with a grin, "I'm sure of it,"

"You're the dream," She growled at him.

The boy shook his head and set his hand on hers reminding Persephone that she was shorter than the boy that seemed three to four years older than her, "I'm real and I'm sticking with that story."

When Persephone learned that she was a witch, she began to wonder if the boy truly was real. Upon falling asleep after her trip to Diagon alley with Hagrid, Persephone quickly navigated her way through the dream to where Byakuran was waiting.

"You look serious, Perse," Byakuran was reclining against one of the nearby tree stumps.

Persephone plopped down beside him and leaned into his side. After four almost five years of spending most of her dreams with this boy, Persephone was the one to initiate physical contact where Byakuran had been the one to do so during their many dreams. Byakuran wrapped an arm around her as she replied, "I'm starting to think you might be real."

"Oh?" He looked at her curiously.

Persephone explained what had happened that day and said, "If magic exists, I'm pretty sure you might too."

Byakuran looked deep in thought for a while before saying, "I do not think magic exists, but if what you said about how the witches and wizards hid themselves is correct, you're probably right."

Persephone shifted around until she was practically laying against Byakuran, "I want you to exist, Bya. You're my only friend and I really want to meet you one day."

Byakuran smiled softly at her making a warm feeling build in her chest, "Then we'll meet somehow. Maybe once your finished that school of yours or I figure out a way to get to you, we'll meet in real life."

"I'd like that," Persephone wrapped her arms around him, "I'd like that a lot,"

"Then it's settled, we'll meet in real life, Little Mage," Byakuran hugged her in return and laid back against the rather large stump.

When Persephone befriended Ron and got sorted, Byakuran was quick to ease the fears that she'd gained.

"You're my friend, Persephone," Byakuran held her against him, "I won't begrudge you gaining more since I'll always be your first friend. Besides, so what if you went into Slytherin, I'll always be here for you even if those idiots shun you. There is more to the world than that school,"

Persephone sighed softly, "I know, but.."

"Fitting in is fine, but being odd is so much better!" Byakuran grinned at her before saying, "Since that school doesn't seem to offer regular school courses, I'll just teach you in here so that you'll never really fall behind,"

Persephone would have groaned, but understood what he meant. The non-magical world was important to and if she was going to meet Byakuran in real life, she would damn well understand the non-magical world. It also meant she would have to learn more languages than the Italian he'd taught her and the English she grew up with.

When she'd befriended Hermione after the troll attack, Byakuran was furious about what happened.

"They let an actual troll into the school," Byakuran was pacing as he growled softly, "They could have gotten my little mage hurt,"

"I got a few scratches and some bruises, but it's better than being dead," Persephone tried to calm him only to realize that she'd made it somewhat worse.

Byakuran strolled forward and picked her up earning a soft squeak before sitting down in her former place. He laid his head on hers while holding her close, "I don't want to even think of the danger you're in, Persephone. It scares me that you could have died and I would have never gotten to meet you."

Realizing why he was so freaked out, Persephone spent the rest of the dream comforting him while trying to ignore the implications of what could have happened.

When she made the quidditch team, Byakuran was both annoyed, but interested.

"I really love flying, Bya," She told him as they sat in the Gryffindor common room, "I feel free when I'm up in the air,"

Byakuran looked at her from his perch by the window and smiled softly, "Then fly as much as possible."

When she almost died during her first quidditch match, Byakuran was furious.

"Someone attempted to kill you while you were on that damn thing?!" They were in Byakuran's room at his house.

"Yes, but I'm fine and caught the snitch," Persephone tried to soothe his worries, "They wouldn't have let me die,"

Byakuran turned to glare at her making Persephone wince. If Byakuran ever lost his smiles or glared at you, it was a clear sign that he truly wasn't happy. Byakuran took a deep breath and told her, "Someone attempted to kill you, Persephone. You do not ignore that."

"I'm not going to!" Persephone defended herself, "We're going to make Snape pay for it,"

"But what if it wasn't Snape?" Byakuran asked making Persephone pause and stare at him before considering the information.

If there was anyone that understood being blamed for things you didn't do, it was Persephone since the Dursleys and a majority of their neighbors blamed her for everything. As such, Persephone conceeded that Snape may not have done it not to mention. Frowning softly, Persephone inclined her head, "You might be right. I'll keep my eyes open."

"Good," He sat down on his bed with a soft huff and pulled Persephone down beside him, "Now, I want you to tell me more about what happened,"

When Persephone talked about the mirror and her invisibility cloak, Byakuran gained a contemplative look on his face.

"Just a note with no name?" Byakuran asked earning a nod, "That seems odd, you should have looked for any traps or had one of your teachers check it for tampering,"

Persephone flushed lightly, "I just got excited about my first actual Christmas presents. I realize now that I should have checked them for tampering, but..."

"Say no more," Byakuran hugged her, "When we finally meet up, you'll be spoiled rotten with all the gifts I'm going to give you,"

"Bya!" Persephone flushed lightly eliciting a laugh from Byakuran in response before he began to tickle her.

Persephone tried to get away, but the elder teen was too strong for her. When she finally called uncle, he grinned at her before they settled down. As she began to regain her breath, Byakuran asked, "What did you see in the mirror?"

Persephone blinked slightly before sighing softly with a sad look on her face, "I saw my parents standing behind me with their hands on my shoulder and proud smiles on their faces," Byakuran hugged her tightly though he said nothing as no words were needed, "I also saw you. You were standing next to me."

Byakuran grinned brightly and hugged her tighter, "I knew you loved me!"

Persephone shook her head with a soft laugh.

When she found out about the dragon that Hagrid had and what happened when it hatched, Byakuran looked severely interested.

"A dragon sounds interesting," Byakuran told her as they sat together on the Astronomy tower, "Did it really burn his beard?"

Persephone nodded and hesitated for a moment before saying, "When it hatched, I felt really weird. It was like something warm ran through my body."

"Really?" Byakuran looked at her curiously, "What else happened?"

"Well," Persephone concentrated on what happened, "When it squeaked after hatching, it almost felt like the little thing was speaking," Persephone shook her head lightly, "When we left, I felt really reluctant and cold for awhile. It felt like I shouldn't have left it there,"

Byakuran gained a pensive look on his face and suggested, "Perhaps you should research that."

"I will," Persephone sighed deeply, "Sometimes, I wonder what's going on,"

"Half the fun is figuring it out," Byakuran pointed out with a grin, "Now, it's time to work on your mathematics,"

When Persephone told Byakuran about the detention and what happened in the forest, the albino was once again furious.

"She not only took way too many points, but sent you into that damn forest for detention?" The man's eyebrow twitched and he growled softly, "Not only that, you encountered a something that probably would have killed you if that centaur didn't save you. Is she mad?"

Persephone winced slightly before saying, "She was probably thinking about my father. He was apparently a big prankster."

"That isn't right especially since you've done nothing to act like him," Byakuran looked even more angry than before, "If I ever meet her, I will make her regret doing that,"

When Persephone killed Quirrell, Byakuran was the one to comfort her and help her work through what happened.

"He would have killed you," Byakuran justified with a scowl on his face, "If I'd been there, I would have killed him for attempting to hurt you," He hugged her close and laid his head on hers, "No one touches my little mage and gets away with it,"

"Bya," Persephone breathed out softly and leaned against him.

She was both touched and disturbed by his words. She knew that he would have done exactly as he'd said though it frightened her that he thought it would be necessary

In the following years, Byakuran proved to be an asset that kept her sane when she was surrounded by insanity. In second year, He kept her grounded when the school shunned her for her ability to speak to snakes. He comforted her when she was blamed for the petrifications and when Hermione was petrified. He ranted and showed his anger when she was forced to face Aragog. He too was puzzled by the Dairy and told her not to use it. He was furious with Lockhart and her having to face the basilisk alone. The worst part was when he learned of it's bite and just how close she came to dying.

In third year, Byakuran laughed his ass off when she informed him of what she'd done to Margery Dursley. He'd been furious at the Ministries failure to keep Black in Azkaban and the subsequent inability to catch the mad man. He'd been angry with the Dementors and vowed to figure out a way to destroy them. He'd been curious about the magical creatures Hagrid showed them and how good Lupin was as a defense professor. He'd managed to convince her to study Ancient Runes even if she wasn't taking it as the subject seemed truly interesting. When Malfoy pulled his shit in care, the seventeen year old was furious at the danger the brat put Persephone in. When they learned of Sirius Black god father status, Byakuran turned contemplative and suggested that they were missing key details. At the end of the year, Byakuran was both angry with the Ministry and curious about Dumbledore's whole stick.

In fourth year, Byakuran was both furious about what happened at the World Cup and Ron's abandonment when her name came out of the goblet. He was a great asset when it came to the first task when he reminded her of what happened with the dragon in first year. Thanks to him, Persephone didn't have to rely on her broom for the task like she'd been planning on and instead talked to the dragon. When the ball came around, Persephone didn't really want to go, but Byakuran convinced her to go as it was a once in a life time chance. Instead of going with Ron like the ginger haired teen had expected, Persephone went with Luna Lovegood on Byakuran's suggestion both because it really was funny and because Luna asked her. Even after the ball, Persephone spent time with Luna and they became good friends though the blonde often left her confused. Sometimes, Persephone wondered if Luna was a seer of some type and knew about her dreams with Byakuran. Fast forward through the rest of the year and tasks, Byakuran became both furious and worried about what had happened.

In Fifth year, Byakuran was angry with the attempt on her life and the ministries response. He was glad that she got to spend time with Sirius before going back to Hogwarts. He became seriously pissed off when she spoke of Dumbledore's avoidance and the 'lessons' with Snape. He was worried about the visions that she had and helped her figure out ways to protect her mind. Upon hearing what Umbridge was doing with blood quills and lack of actual lessons, he was absolutely enraged and vowed to kill the woman if he ever saw her. He found Hermione's idea worth trying and helped convince Persephone to agree to it. When Arthur Weasley was almost killed, Byakuran was seriously worried about the visions and wouldn't let go of her every time they dreamed together. However, one day halfway through the school year, Persephone stopped dreaming of Byakuran and became despondent.

She became lost as the pain of not being able to see her oldest and dearest friend filled her. The worry at what was going on and why the dreams stopped were constants in her mind. She was easier to anger which led to increasing detentions with Umbridge up until Persephone just stopped going near the woman completely. Persephone continued the defense lessons as they were the only that made her feel even remotely happy. Luna kept her from getting too lost and became the only person that Persephone really talked to. When Sirius' life seemed to be in danger, Persephone acted recklessly and went to save the man that had become her father figure. When he was killed, Persephone was filled with rage, yet everything seemed startlingly clear to her.

Upon finally getting managing to catch Bellatrix, Persephone didn't hesitate to kill the bitch as she knew that Bellatrix would only continue to cause trouble. Not to mention, Persephone wanted to be the one to end the bitch for taking one of the only decent family members she had away from her. When the whole thing with Voldemort occurred, Persephone felt cold and only managed to fight off the bastard using the pretty flames that seemed to fill her body. When Dumbledore sent her to his office and told her what was going on, Persephone stared at the old man with cold eyes and stated, "Only a fool would think to withhold information from the one it pertains to and blindly believe in a prophesy made by a desperate drunkard. It would seem you and Voldemort are on in the same when it comes to such things," She relished in watching him flinch, "Not only that, you truly believe that a teenager with barely any experience could fight him and win just because of 'love'. If you honestly think that I have any intention of doing what you ask of me anymore, you're even more of a fool than I thought. I trusted you once upon a time, Headmaster, but I will no longer do so. Stay away from me and do not attempt to dictate my life anymore, I only have room for one fool in my life and you are not him."

Without waiting for an answer, Persephone used her magic to destroy the door and leave a shocked Dumbledore behind.

Persephone was numb as she left the magical platform and entered the non-magical one. She was too tired and filled with grief to really notice the world around her until an achingly familiar voice called from behind her, "Are you just going to ignore your oldest friend, Little Mage? I know that I haven't been sharing dreams with you for a while, but you can't be that mad at me. I have reasons for it!"

Persephone froze before slowly turning around as she ignored Tonks and Moody. Upon seeing the familiar white hair and pinkish purple eyes, Persephone felt her breath catch in her throat as hope began to burn in her chest. Byakuran looked just as he had the last time she saw him only this time, he wore a white jacket over a dark purple shirt. Persephone swallowed softly as she took a step forward with a hoarse whisper, "Bya?"

"Persephone," He gave her a breathtakingly warm smile and opened his arms, "It's really me,"

With a soft sob, Persephone darted into her arms and hugged the albino for the first time in real life. He hugged her in return as she whispered, "Bya, you're here. You're actually here."

"And I'm not going to leave you alone," Byakuran promised her as the tall boy hugged her tightly.

Persephone pressed herself closer to warmth of the boy upon hearing that. She'd finally gotten her dream of meeting him and he really was real! Persephone took in his overly sweet scent and sighed softly as she leaned into him. Annoyingly enough, they were reminded of reality by Moody demanding, "Let go of Potter, boy. She's coming with us."

Byakuran stiffened before carefully releasing her prompting Persephone to do the same as hurt filled her. When she saw the look in his eyes, Persephone relaxed. Byakuran chose to ignore the two magicals and focus on Persephone with a slightly fake smile that the teenage witch wanted to remove. He held out a hand to her, "Persephone, come home with me and you'll be free of these people. You'll never be forced to live with your relatives and will never have to see them again. We can be together so long as you come home with me. Will you come home with me?"

Persephone stared at the hand he'd extended towards her. She saw the odd ring on his finger that hadn't been there before and felt the power leaking off of it. Instead of focusing on it, Persephone looked back up at Byakuran as she thought about everything. She wanted to go with him. She knew he would keep his promise to her and unlike the wizarding world, he actually cared about her. Byakuran knew everything about her just as she knew everything about him. He was her best friend and would die before he willingly hurt her just as she would do the same. With that in mind, Persephone smiled warmly at him as she took his extended hand and felt a spark travel through her at the skin to skin contact, "Always."

Byakuran pulled her to him as he waved a hand, "Please get Persephone's belongings from those two and ensure they don't follow us."

"Yes, sir!" A group of men quickly agreed.

Before Persephone could question it, Byakuran began leaving the train station, "Come, it's time we get going and head home."

"Will you tell me what happened?" Persephone asked as they walked.

"Of course," Byakuran looked down at her with a warm smile on his face and warmth in his eyes, "We have a lot to talk about,"

With a content smile, Persephone allowed Byakuran to lead her out of the train station. She ignored the calls and shouts behind her. They didn't matter anymore. All she cared about was being with Byakuran. So long as she had him, Persephone would be content.

A bit long, but you guys deserve it and Byakuran is my favorite at the moment. Tell me what you guys think. Next up is Colonello once more and this time it won't be sad!
