Chapter One
Severus Snape was many things. A Death Eater turned Spy, the Head of Slytherin, youngest Potions Master, and skilled spellcrafter. He could out duel even Fillius Flickwit, and could outmaneuver Albus Dumbledore in chess. He was prejudice against those outside of his own House in Hogwarts, for no one looked after his snakes, unlike the others, but he would not harm a child. Rather, he'd sooner lay down his life for one.
That was how he found himself staring down at black hair as the boy held tight to his robes. His whole body wracked by sobs. He never thought he'd be in the position he found himself in, and he doubted the boy did either. However, how could he turn away his best friend's only child?
"Mister Potter, I must insist you calm down. I'm not going anywhere." The man murmured. "I've never once lied to you, and I won't ever break a promise to you." Tears dried as the boy calmed down. "Now, care to tell me what is going on?"
He'd came across the boy sobbing, curled up on himself in an empty corridor. It'd taken some cajoling to get the child to unfurl. Gentle, callous covered, hands had the child throwing himself at the potions professor. Clinging as if it was the only thing keeping him grounded. Then the tears began anew.
"M-Harry, please, tell me what is wrong, child."
"I can't go back!" The child shook. "Not after what happened. He'll do it again! I can't. Don't make me go back to that house. Please, I'll cook, clean, whatever you want, just don't make me go back!"
"Go back? You mean to your aunt's? Harry, what happened that makes you afraid to return?"
"Dobby, he dropped a cake on Vernon's boss to make me stay at the Dursleys. V-Vernon said that-that i-if he can-can't get a pr-pro-promo-promotion th-that I w-would have to ear-earn my k-keep a-again." The body in his arms shivered. "I can't. I can't do that again!"
"Earn your keep?" The man shook at the implications. "Harry, what did he do? What did he make you do?" He dreaded the answer.
"I don't want to be touched again."
In that moment, Severus knew that his next action would change their lives.
"It's okay, Harry. You're not going back." The man swore, standing and taking the twelve year old along with him as he walked to his quarters.
Within minutes he was packed, and had his personal elf retrieve the student's belongings, and owl. Upon her return, he had her apparate them to his home in Paris, France, where his cousins through the Snape side, the Dupain family, lived.
Once there, he caught the boy up on his muggle schooling, and took over his wizarding schooling. By the time summer rolled around, Harry was caught up, and Severus only had one more thing to ask the boy.
"Harry, how would you like for me to adopt you?"
Thus, Harry James Snape was reborn.
Harry yawned as he entered his new classroom. He noted, absently, that his cousin was late, but didn't worry, having heard from the girl's mouth herself that she was often tarty due to being clumsy. He nervously sat down next to a redheaded girl that dwarfed him in height.
Twenty minutes later, he was glaring at Chloé Bourgeois from his spot beside his cousin. The girl was in near tears as she spoke with their desk partner, Alya Césaire. All over a boy who never showed up.
Having a magical spell cast on his classmate, now that was something he could have done without. Though watching Marinette fall head-over-heels for Adrien Agreste was hilarious. Harry had a feeling that it was the first crush she'd ever had.
The months slowly went by, and it seemed like Ladybug and Chat Noir were constantly popping up just in time to save the day. Nearly everyday, it felt. Others joined them in the form of Rena Rouge and Carapace.
However, Harry noted every time the two superheroes appeared, a certain blue eyed girl, and blond boy, would disappear. Who should appear, but a blue eyed girl and a blond boy? Albeit, in costume. So he laid a trap for his cousin, wanting to know if she was truly placing herself in harms way.
He didn't make it to witness her transformation into Ladybug, but he knew how to be patient, and waited for Marinette within the locker room, arms crossed. The girl missed him, seeing as he was hidden in the shadows of the room, as the last beep of her Miraculous was heard, and a bright light covered her.
"Marinette Dupain-Cheng, you are in so much trouble!" Harry's voice had her whirling around in panic, tripping over her own feet as she held a small red being with black polka dots. "The Miraculouses? Do you know what type of history you're holding onto? Using to fight evil?"
"H-Harry? Wha, but, how, you know, what?" The boy pinched his nose in annoyance.
"Yes I know about the Miraculouses."
"How?" The red being demanded, voice high. Harry lifted a brow. "How do you know about-"
"About the Miraculouses, and the Kwami within?" The bug like being flinched. "I'm a wizard, and they are well documented as lost artefacts."
"We need to get to Master Fu." Harry gaped slightly.
"Wang Fu is still alive? But he's a muggle, isn't he?"
"He's also the Great Guardian." The Kwami shrugged. "We must be informed of this. If other Wizards are able to figure out who Marinette and Chat Noir are, then it could spell distaster for mankind.
Thirty minutes later found Harry being inspected by a man he was barely taller than. The boy squirmed as the man turned his gaze to his cousin.
"He only figured it out because you are close. The Glamour is weaker against Wizards, so it isn't surprising he could tell." As the man spoke to Marinette, Harry felt a pull to a phonograph. "Child, is something the matter?"
"I feel a pull towards the phonograph...like my wand." Golden brown eyes widened in shock. Walking over, he pressed buttons, allowing the secret compartment to open. Harry's eyes were instantly drawn to a metal band. It looked like a snake biting it's own tail. He hesitantly lifted it out.
A bright light, and another Kwami floated before him.
"Hello, child. I am Sass." The snake like sprite smiled at Harry. The boy smiled back, hesitant. "I have waited over three hundred years for my next wielder, child."
"Harry. My name's Harry."
"Hello Harry." The Kwami turned to Master Fu. "I am sorry, Guardian, but Harry needs me." The being smiled, "and I was why he could see through Ladybug's glamour. I allowed it, because I knew that he would be brought here."
"Sass!" Tikki and Wazz scolded.
"What? Upset because you have not allowed your Chosen to see who their partner is?" Tikki fell silent with a huff. "Which, by the way, you need to find out, Marinette." Sass turned to the now pale girl. "With Hawkmoth closer to us now more than ever, we need to be able to trust each other. Chat Noir was not even able to help this last time because you do not know who he is. Next time, tell him it is time. You trust him, do you not?" The girl sagged, hugging herself.
"But what if he doesn't want Clumsy Marinette to be Ladybug?" The girl had tears filling her eyes. "I'm really not that special. My designs are mediocre at best-"
"Stop that!" Harry chided, frowning at his cousin. "Do you think I'm a freak for being a wizard?"
"Wha-?" The girl jerked to stare at her cousin. "Of course not! I'm Ladybug-"
"Exactly. You're Ladybug. Ladybug is not Marinette." She opened and closed her mouth in her confusion. "It means, while you were Chosen, it didn't mean you had to keep your Miraculous. You could have given it to someone you thought more deserving." Marinette hung her head.
"I almost did."
"But you didn't." Tikki spoke up. "You chose to keep me, and become the newest Ladybug. You're perfect, Marinette."
"Tikki..."
"Just trust us on this, Mari." Harry bumped his shoulder against her. "Besides, I think you'll like who Chat Noir is."
"You know who he is?" Bluebell eyes looked up at him, making Harry squirm.
"No? I mean I have a guess, but it's only a guess. You'll just have to wait and see. Now, I have to get home and help papa with some potions. I'll see you tomorrow?"
"If an Akuma doesn't attack." The girl agreed. They paused. "Wait, why can't we see through Hawkmoth then?" The Sprites shared looks.
"It's because we haven't met him yet." Harry pipped in, looking to his Kwami to see if he had it correct. Sass nodded. "It's because you can't know who they are, if you've not seen them in costume before."
"That's just it. We were thinking it was Gabriel Agreste until he was Akumatized." Harry frowned.
"What does it matter if he was Akumatized? Marinette, if it weren't for Miss Bustier, you would have been." The girl lowered her head in shame. "That wasn't your fault."
"But Harry, what would have happened to Tikki? He would have been in my head. He would know that I'm Ladybug. Not even Miraculous holders are safe! I don't want to have to fight you, or Chat, or Alya-"
"Alya?" Harry narrowed his eyes at his adoptive cousin. "She's Rena Rouge...and if I know you, Carapace is Nino." The girl grimaced. "Why aren't they permanent heroes?" He turned to Master Fu, who looked, or tried to look, innocent. "Them having their Miraculous Gems on hand would be helpful, guardian. I can't tell you how often my day has gone to shit because I wasn't expecting something to happen! I'm lucky that I haven't been Akumatized! I've been depressed, and hateful at the world, since I moved here."
"Yeah, I guess we are lucky that didn't happen. You're a wizard, right? What would happen if one was Akumatized?" Master Fu made a distressed noise.
"I pray that never happens." The man bemoaned, "now, children, I have an appointment. Why don't you go give this Alya and Nino their Miraculouses."
"Seriously? Where are they?" Harry groaned, looking around.
"Why don't you transform already so they don't know who you are?"
"No. You know who they are. We know who they are. Chat will know as soon as he gets here. We need their help, Mari. You need help. As soon as they, and Chat, get here, you will be unmasking, as will Chat. What if one of us died? How would we explain to our families that one of us aren't coming home. I've fought evil before, Mari. The longer they hold a grudge the more dangerous things get."
"Trust your cousin, Ladybug." Sass smiled kindly at the girl. The masked teen sighed, looking around before changing back into Marinette, glad that they were hidden still.
"Marinette? Harry? What are you doing here?" Alya's voice sounded not two minutes later. The cousins shared looks.
"We are waiting on two more people." Harry explained, just as Chat Noir dropped beside him. "Er, make that one."
"C-Chat Noir?" Alya stuttered, before looking at her friends. "What's going on? Are we waiting on Ladybug?"
"Nino. We're waiting on Nino." Marinette glanced over at Chat Noir, before lowering her head. "I promise, it will make sense once Nino gets here." The girl mumbled something that sounded like 'I hope' under her breath.
"Dudes! What is Chat Noir doing here? You didn't tell me he'd be here, Harry!" The boy rolled his eyes, tossing a box shaped item at the older teen. Who nearly dropped it. "Whoa! Wha-" Alya was gaping at her boyfriend, turning just in time for Marinette to hand her the same style of Chinese box. "No way."
"Why do you have two Miraculous boxes?" Chat Noir demanded finally. Marinette and Harry shared nervous looks.
"No way! Why didn't you tell me, girl?" Alya demanded, hurt in her eyes. "I wouldn't have told anyone!" Marinette shook her head.
"I was told not to tell anyone."
"But you're Ladybug! I could have-" Alya was cut off by a loud thunk. They turned to Chat Noir, who had fainted. "Oh my gosh! Chat Noir didn't know?"
"Harry convinced her that he needed to know." Sass said, appearing from Harry's turtleneck collar. Tikki poked out from Marinette's purse. "I can't believe the cat fainted."
"Hush, you." Harry chided. "He just learned who his Lady is in a surprising way. I just can't wait until she realises who he is." The two Kwamis snickered in agreement.
"You know who Chat Noir is?" Alya demanded in surprise. Harry grinned, nodding.
"Sass needed to meet me, and knew I had to be able to see through their glamours. Let me tell you, you're going to be shocked. Now, aren't you going to let Trixx and Wayzz out?" The two startled, before doing as suggested. "Wayzz, are you sure this is okay?"
"Master hasn't used me in nearly fifty years. He's much too old, Harry." Wayzz admitted, "shortly before the two of you arrived, he planned on pulling Nino aside to give me over, and start training him in becoming the next Guardian." Nino gaped for a moment. "We'll talk later, Nino."
"Okay, lil' dude." Nino knelt to poke at Chat Noir.
"Oh my head. That was one heck of a dream. Oh, Nino, what are you doing in my room this early?" The group of four just blinked at him, before Nino started swearing up a storm. Alya was gaping at her boyfriend, the laidback D.J. that never got so shell shocked. "Nino?" The cat boy demanded, sitting up. He looked around, spotting Harry, Alya, and finally Marinette. His eyes widened at the sight of the Kwamis. "No way."
"Dude! Dude!" Nino spun to Marinette. "Dude!"
"Nino!" Alya snapped, bonking him on the head. "Just chill!"
"Adrien is Chat Noir!" The black cat of destruction stiffened. "Chat Noir is in love with Ladybug! Marinette is Ladybug! Marinette is in love with Adrien! I can't believe, mind blown!" Alya gaped a moment before cracking as well, laughing in sync with her boyfriend. Marinette was shocked to her core, and red as a cherry. Harry was snickering at her side at the complicated matter of her love life.
"What?" Chat Noir stuttered, eyes wide.
"In simple Terms, Adrien, you like Marinette, and Marinette likes you!" Harry grinned, pushing his cousin towards the cat. "Now, why don't you un-suit, and I'll take us back to my place for food and a talk since it's the closest?"
"C-Claws in." A flash of light, and Adrien replaced the superhero. His eyes hadn't left Marinette. As if he was just now seeing the stuttering mess for who she really was. "My princess and Lady are the same?" The blond's eyes widened, and he was moving before the others realised Marinette had fainted. "Y-you said your place, right, Harry?" The dark haired boy nodded, smiling calmly. "Why are you so calm about this?"
"Chat Noir is a hero, and Adrien is a sweet boy. Tell me something, even if Marinette wasn't Ladybug, would you be upset to learn she likes you?" Harry lead the way, giving the blond time to think.
"I'm not, and I won't be, and now I don't have to choose." Adrien admitted. The younger boy smiled brightly.
"And that is why I'm not upset. Marinette feels the same way. It's just, she fell in love with Adrien first. You gave her your umbrella, and you were kind to her, even though she was quiet mean to you that day, thinking that Chloé's pranks were yours." Adrien flinched.
"I thought she was nervous because she felt guilty still." He admitted, looking up when they reached a fenced yard. "You live here? Harry, this place is bigger than mine!"
"Yes, well, I am the heir to the Potter and Prince fortunes." Harry admitted, leading everyone in, and having Adrien lay Marinette down on the couch. They sat down around her, and Harry crossed his legs, meeting their gazes. "Marinette was terrified. She thought if you knew that she was Ladybug, you'd be disappointed. Adrien, before this year, Marinette only had Nino as a friend." The tan boy flinched, not meeting anyone's gaze as they looked to him. "I'm still not sure why that is."
"Marinette has always had trouble making friends. I've been her friend since our mothers were pregnant together." Nino glanced at the dark haired girl. "She has anxieties that don't make sense. She thought she was ugly for the longest time...she didn't always look like this, so I suppose that's not a surprise."
"What do you mean?" Harry asked, confused.
"You're adopted, right? Has Sabine shown you pictures from Marinette's childhood?" Harry shook his head.
"I don't have childhood pictures. I asked not to be shown anything before Mari was ten." Nino nodded in understanding.
"Marinette, she wasn't fat, but she was rounded. She was smaller than Mylène, but because she's small, she had a thickness to her that stood out. I tried to keep her confidence up, but with Chloé's bullying, she was always doubting herself. When we were ten, Mari got sick. She couldn't eat, she couldn't sleep. They thought she was going to die the way she was going. She was so thin, it was terrifying. Just breathing around her made you think you'd break her.
"Then, one day, she woke up starving." Nino smiled sadly. "She ate so much, she threw up. We had to ease her into eating again. She was taken off of the IV they had her on, and she gained back a healthy weight. I was just glad to know my best friend wasn't going to die." The boy gazed at the girl still out cold on the couch. "In a way, that's why I was freaking out so much. She flirts as Ladybug with Chat Noir. Now she's going to be second guessing every one of her moves against you, Adrien. As both civilian and hero."
"But I just want her to be herself!" Adrien protested, still horrified at what he was hearing. "I like Marinette just the way she is, even if she was so nervous around me! She's one of my closest friends." Harry smiled at him.
"Thanks Chaton." The group jumped, looking at Marinette, who was giving Nino the stink eye.
"They had to know."
"Did they ever learn what was wrong?" Alya demanded.
"Uncle Severus fixed me with potions." Marinette sighed, sitting up. "I went through something called Magical Defincienty. It...my magic was leaking out of my body faster than it could replenish." Harry inhaled sharply, shock and disbelief, but understanding, filled his face.
"Oh Mari..."
"It hurt so much. He had to bind my magic."
"Well, that bind is no longer there." Tikki spoke up, from where she was munching on a macaroon. "I provide enough magic for you to be sustained. If we were ever forced from each other, then you'd need a new binding." Marinette gasped, looking around at her friends, who were just as shocked.
"Does that mean all of us have magic?" Adrien asked Plagg, who nodded. "I thought it was just me."
"Only those with magical cores can use a Miraculous." Harry spoke up, seeing as the cat was eating cheese. "Lion, Raven, Badger, and...and Snake, they belonged to someone important in wizarding history." The boy turned to his Kwami, who was eating a boiled egg. "You were with Salazar. How did the Guardians get you back?"
"Salazar wasn't as bad as History made him out to be. Admittedly, I was given back at the same time as the others, long before the fight that sent Salazar running." Harry nodded, accepting it as it was.
"Does that mean your holders have to be able to use parseltongue?" Marinette gasped in surprise.
"That's right." Sass turned to the rest. "The reason Marinette chose you, is because she could sense your magic. Out of everyone in Paris, you're the ones she trusts. The ones she knew could handle the power."
"Wait! I don't have magic! I'm a squib!" Nino protested.
"I don't know what you're talking about. I've never had magic!" Harry frowned, before standing, and motioning for Alya to follow him. He lead her to a room, and office, off the main hall.
"Dad, can you run a diagnostics on my friend? I think something is wrong with her. She says her magic doesn't feel right." Harry told his dad when Severus turned around The man sighed, flicking out his wand, and running it around her aura field. "Well?"
"She'd bound, and a few memory charms on her." The man frowned. Then dark eyes widened in surprise. "Harry James Snape, why did you lie to me?" The boy sighed.
"My friends all have magic, and two of them are bound." The man's eyes narrowed. "We're Chosen Miraculous Holders." The man shook his head.
"Why can't you be a normal child, and run from trouble. Who else do I need to take a look at?"
"Marinette, and Nino." His eyes widened, and then he was hurrying to check on his cousin's daughter.
"You're all fine." Severus admitted a few hours later after the binds had been broken on Nino and Alya by their kwamis. "Just, if you're hurt, come to me."
"Of course, dad." Harry agreed, smiling.
"Harry, how could you tell him?" Marinette demanded.
"Because he can use Occlumency. Which we will all be learning, because I don't want Hawkmoth taking over our minds." Harry demanded, crossing his arms.
"So, what does the snake stand for?" Adrien asked as they finally got some food. Pizza, handmade by Harry and Marinette. "Plagg is Destruction, Tikki is Creation, Wayzz is Protection, and Trixx is Illusion."
"I stand for Rebirth. When Harry uses the ability Kiss, he can bring anyone back to life within ten minutes of their passing." The boy stiffened, eyes widen in surprise.
"So, he's like a healer?" Marinette clarified, getting a nod. "That means no frontlines for you, Harry."
"I'm not useless in a fight, Mari!"
"And I didn't say you were!" The girl stomped her foot. "Your my younger cousin! I don't want you fighting, Harry! You've fought enough!" The boy fell silent, staring at his cousin in wonder. "Let someone else fight, because you're irreplaceable, Harry. There will be other Ladybugs, other Cobras, but there is only one Harry James Potter-Snape!" Harry slowly nodded.
"Fine, but you have to promise you won't risk your own life. That if it's too dangerous we will regroup and plan. You're my family, and I never let my family get hurt." Their friends shared smiles. Harry spun, pointing at Adrian. "And that means if you ever hurt Mari, you won't be able to hide from me."
"Harry!"
Well, so, like I said, you don't have to read this. This is just to tell people that updates will be irregular. Could be back to back or every few months. I'm currently working, and writing my own novel. I shouldn't take more than half a year, though.
Thanks for reading!
