This was a request for gender-bent Kagami (Kagam) and Cristina who is Marinette's sister. This was actually super fun to write and I'm very proud of it. Also, I do recommend looking up gender-bent Kagami cause she's cute even as a boy. I hope you all enjoy!

Cristina tied her just-washed hair into two twin ponytails. She braided her long dark locks on each side as she jammed to her shower playlist. She looked almost identical to her older sister Marinette. They always got asked if they were twins.

She was only a year younger but took more after her father than Marinette did. Her hazel eyes were just like his. She tied her waist-long braids at the end and smiled at herself in the mirror.

Cristina grabbed the bowl of popcorn off the counter and went back into her room. Kagam was due to show up at any moment. Both her parents had fallen asleep already or they'd be in big trouble. She set up the projector and had the movie at the ready. A gentle tap at her window brought a smile to her face as she rushed to open it.

Ryuko stepped into her room silently. He had a red mask with black and yellow fang markings. His suit was mostly red other than the vine-like marking circling from his chest to his stomach and around his left leg. He had a pair of blunt horns that stuck out from his dark black hair.

"Hurry up," she pushed him further inside and closed the window. Ryuko detransformed and in his place was Kagam. She had accidentally seen him change back with Ladybug near her house one day and kept it a secret between the two of them. He was a year older but they became fast friends once Marinette introduced them.

"What movie are we watching?" He asked, ruffling his hair. His kwami landed on her desk, nibbling on a snack.

"Frozen of course!" Cristina said excitedly as she shut off the lights. Kagam wasn't exactly excited about a kids' movie but she looked so happy he kept it to himself. They sat on her floor cushioned by blankets and pillows. She sat next to him after hitting play and snacked on the popcorn she'd made. Only a few minutes into the movie Kagam was bored. He rested his chin in his hand and gazed at Cristina. Her wide eyes watched the movie with wonder. Everyone said she and Marinette looked like twins and while they were similar he had to admit Cristina was much cuter in his eyes. She noticed him staring and scowled at him.

"Kagam, you're supposed to be watching the movie. Do I have something on my face?" Cristina turned to him, disappointed he missed the funniest part.

"No I was just thinking," he smirked.

"Thinking what?" she asked, intrigued.

"You should be in the louvre with how beautiful you are," he smiled genuinely as she flamed red.

She smacked his arm after she came to her senses. "Stop playing you don't even mean that," she huffed, turning back to the movie. His eyes lingered on her face a few seconds more before turning back to the movie.

The movie hadn't even ended when he looked over and she had fallen asleep. It was rather late since they had to wait for her parents to sleep. Kagam smiled, picking her up carefully. She barely stirred as he lifted her into bed and covered her with a blanket. He caressed one of her braids, kissing the pleated hair that smelled like strawberry shampoo.

"I wasn't playing around," he whispered against her hair before leaving.

Cristina blinked her eyes open, heat spreading to her cheeks. She covered her face with her hands. She was pretending to sleep like a kid who wanted to be carried into the house by their parent after a long car ride. She rolled over into the cool pillow to calm her nerves. Her heart was racing.

Cristina pulled at her eye bags in the mirror. She got no sleep last night. She had stayed up all night thinking of every single moment they'd shared together. How had she been so blind? What was she going to do now? And did she even like him back?

She had finally convinced herself to get over Luka. She knew he was in love with her sister. Marinette was in love with Adrien and Luka knew that so it wasn't futile but Luka had never seen Cristina as more than a friend. More for herself than anything it was best to get over him.

Cristina snapped out of her thoughts and got ready. She pulled on a purple pleated skirt along with a white shirt that she tucked in. She wore a cropped black jacket like usual to hide her kwami. Blazze hid last night since Kagam didn't know she also had a miraculous. She felt bad for not telling him but the timing was never right. The anklet she wore sat loosely above her shoes on her ankle.

"Marinette! You're going to be late!" she yelled up the stairs before leaving. She heard crashing from above and knew she was finally awake. She quickly made her way to school so as not to get the same tardy reputation as her sister.

"Morning," Luka gave a wide smile to the girl. She gave a tight smile and passed by him with a wave. He caught her arm and she turned back to him. He released her, having caught her attention and rubbed the back of his neck.

"I was wondering if anyone had asked you to the ba-" Kagam cut him off as he stepped next up Cristina.

"Goodmorning Cristina," Kagam smiled at her. Her heart fluttered. Why was it so different now when he said her name?

Cristina noticed the difference immediately from when Luka had spoken to her. Was she in love with Kagam? They had been friends for a while now and she had never considered it but the longer she thought the more she realized she liked him back.

She blinked at him with no response, her face flaming and both boys looked at her concerned. Cristina pulled away from them making some excuse and heading inside. Kagam eyed Luka and followed after her.

"Cristina?" One of her friends tapped her as class began.

"Oh uh sorry, what were you saying?" Cristina was very starstruck by her new discovery.

"I was asking if you had a dress for the ball tonight?" she sighed with a chuckle at her airhead of a friend.

"Of course! Marinette made me one," she beamed. She didn't know what she wanted to do, unlike her sister. She loved baking just like the rest of her family but sometimes she wished she had a set goal like Marinette.

"Wow it must be nice to have a fashion designer for a sister," she rolled her eyes and focused on the class.

She grew more excited and anxious as the day went on. The ball was going to be fun but she didn't have a date. Class ended and she walked out of the school, catching a glimpse of Marinette an Adrien walking together. They were going together. Kagam stepped up next to her, noticing her gaze.

"Do you have a date?" Kagam asked, shocking her.

"No," Cristina let out meekly.

"Yes you do," he chuckled. She looked at him confused not expecting his next few words. "You're going with me." She stopped in her tracks and he followed her lead, looking into her eyes with a serious expression. Her eyes widened and her heart raced. She hid her happy smile with her textbooks.

"Fine, but don't be late," she scoffed with a shy smile. His eyes widened. Her usual response would be telling him not to mess around.

"I-I won't," her words had thrown him off, a slight blush on her ears and cheeks as they went their separate ways.

Cristina squealed as she got into her room, throwing her things on the bed and beginning to get ready. She took down her hair that now fell in soft waves from the braids and did a small amount of makeup. Her dress was a beautiful lilac. The v neck had just the right amount of coverage and sinched at the waist before it flowed in ruffles from the waist down to the floor.

Adrien picked up Marinette and she tagged along in his limo after they were ready.

Kagam had just finished getting ready, tightening his tie as he began to leave. His mother stepped between him and the door.

"Where do you think you're going?" His mother asked sternly.

"Uh, the ball?" He said confusedly. He didn't understand why she was angry.

"Oh no you're not. You think I didn't know you've been sneaking out to do who knows what? You're grounded." His eyes widened in shock. At least she didn't know he was a holder but this was not happening right now. She pushed him back into his room and locked the door behind her.

He jiggled the handle and sighed. Could his night get any worse? He looked to the window, Longg coming out from his jacket pocket. He had already snuck out of the house multiple times what was one more.

Cristina stood at the drink table awkwardly, she looked around for Kagam but he wasn't there. Every time the door opened she hoped it would be him. She sighed and set her drink down, heading outside into the cool air. She was disappointed, but also worried.

Luka followed her out. "Cristina are you okay?" he asked, placing a hand on her waist. She didn't know why but she felt the urge to cry. For once she felt like everything was finally falling into place and now it was crumbling away. She was confused.

Luka noticed her expression and pulled her into his arms, spinning her to the music. She blushed as the people outside watched them. The music was faint but still audible. He smiled down at her and she tried to smile back.

Students were oohing and awing as they passed the two dancing. Marinette and Adrien came outside, as they'd lost sight of Cristina. Marinette was surprisingly protective of her sister.

Ryuko had never rebelled against his father before. He surprisingly felt free. He knew once his father found out he'd be toast but he wanted to enjoy the moment. He landed on a building near the ball, watching the people go inside. Two people were dancing, the blue hair familiar. He gritted his teeth as he saw Cristina dancing with Luka. Of course, Luka would take this chance to step in while he was away. And just when he was getting somewhere.

He used the power of the wind dragon, gaining deep red wings and a scaly tail. He swooped down, people around his screaming as they didn't recognize the hero. He scooped Cristina into his arms and flew away into the night. Luka watched them fly away in shock. Adrien and Marinette looked at each other worriedly but they knew they could trust Ryuko.

Cristina gripped onto his neck as they flew over rooftops. He landed nearby, but far enough that the students couldn't see them. He set her down gently.

"Ryuko what's wro-" Ryuko crashed his lips onto hers, pulling her close by the waist. He put all of his emotions into the kiss. His dragon-like wings wrapping around her along with his tail that snaked around her waist.

Her eyes widened before she melted into the kiss, resting her hands on his chest. She kissed him back softly, calming him. She could feel all of his jealously and sadness and some anger through his soft lips. He slowly, pulled away, his hands never leaving her hips. She stared into his yellow eyes.

"Y-you know…" she stuttered, still starstruck form the kiss. "I love you… Kagam," she said quietly. She had never said it out loud but she knew it was the truth. His breath caught in his throat as he stared at her, searching her eyes for any deceit.

He picked her up and spun her around, smiling wider than she had ever seen before. She giggled as he held her close. He set her down and rested his forehead on hers. "I was so worried that you were still in love with that blue-haired boy," he whispered. He was still too angry to say his name. He let out a relieved breath, happier than he ever could've imagined.

"I love you too, so much more than you can believe."
