A/N: This is set in Japan. I thought it would be weird if a Japanese had a French name like Chat Noir, so I changed it to Black Cat. Hawkmoth's name is also changed to Kochou (蝴蝶 or "butterfly" in Japanese). Also this time Marinette isn't Ladybug, Adrien isn't Chat Noir (in case you get confused). I just took elements from ML and stuffed them into the Assassination Classroom universe. Also let's assume that no one can tell their hair colour and voice are the same.
"Good, let's move on to the next chapter."
Hayami flipped a page. She was revising alone on a peaceful Sunday. Her second year of middle school had just begun, but she didn't allow herself to slack off.
There was a loud bang from outside. Hayami looked out of her window, and what looked like a gigantic bird was flying outside. Hayami blinked. It looked like a huge Pokemon? What the hell was that?
She turned the television on and she the local news was broadcasting the huge bird. "The so-called bird is actually a human who wears huge wings and calls themselves 'Freefeather'," the reporter said. "It is now wreaking buildings and causing damage."
A rather shaky video was shown, with Freefeather squawking, "I will have freedom! No one can limit me anymore!"
That's… that's supernatural! Hayami thought worriedly. What's happening?
And that was when she saw a jewelry box on her desk. It certainly wasn't there before, Hayami thought, but maybe she had overlooked it because she was too focused on her work.
Her curiosity got better of her and Hayami opened the box cautiously. A bright red light shone out of it, and Hayami shielded her eyes…
"Let's go oniichan!"
A four year old little girl pulled at her older brother's hand, who was a full decade older than her.
"Ah, okay, Mi-chan."
Chiba let his younger sister direct him, giving her the freedom to choose where they were going.
"Can I have a lollipop?" Minori asked Chiba excitedly, pointing at a candy store. Her eyes were shining and she looked adorable.
"Mom says you can't have any sweets this week." Chiba said gently. "So maybe next week?"
Minori looked disappointed. "Fine, I guess." she muttered.
Chiba didn't like seeing his sister upset, so he came up with an idea. "Say, let's visit the toy shop-" Chiba saw a shadow above him. "Look out Minori!"
Minori felt someone push her and she fell to the ground, fortunately without any scratches. She quickly realized something, or rather someone, was missing.
"Oniichan!"
A large piece of debris stood where she had been a few seconds ago. Minori ran to it urgently. "Oniichan? Are you there? Are you alive?"
There was a grunt. "I'm fine, Minori." Chiba replied. His leg was stuck under the debris and he tried to tug it out. He saw more parts of damaged buildings raining from the sky, and a huge bird flying between them.
"Listen to me! Minori, go to somewhere safe with people and police! Run!"
"B-but how about you?" Minori stuttered.
"Don't worry about me!" Chiba yelled as he tried to free his leg."I'll be fine!"
"I'm not leaving you!" Minori sobbed.
"If you stay than no more sweets for a month!"
A window pane shattered near them and the glass shards flew towards them. Minori saw the broken street and the scratches made by the flying shards, looked back nervously before running off crying.
Chiba saw the mess falling down, closed his eyes and said a small prayer. It seemed like the end of the world…
"...and that's what the ladybug miraculous powers are about!" A small, red, bug-like creature explained.
"So… with these earrings I can fight the bad guy and bring peace?" Hayami asked. The initial shock of Tikki, the ladybug kwami, appearing had worn away due to more exciting things happening outside.
"Yeah. But do you want to know why you were chosen-"
"I am sorry for interrupting you, but at this point I don't care if I am made to be a superhero or not, I just want to save the people." Hayami's mind was spinning so she chose the most logical path. "Tell me what I need to do to defeat the bird and we'll talk about this later."
Tikki blinked. This was one of her chosens that focused more on actions than words and she could see the determination in her eyes. Her guardian had been observing Hayami for some time, and knew she was trustable.
"Okay, put on these earrings. You transform by yelling "Tikki, spots on!". You can use your yoyo to fight. You can yell "Lucky Charm!" and throw your yoyo in the air, and an item will fall down to help you defeat the enemy. You will detransform 5 minutes after you use the Lucky Charm. The enemy is called an akuma. Find an item that the akuma, or an evil butterfly, is in. Break it and cleanse it using your yoyo. The akuma is sent by Kochou, and he wants to use the akuma to get your miraculous. Don't let him. Throw your Lucky Charm in the air while yelling "Miraculous Ladybug!" and everything will turn back to normal. After you detransform, you use up all of my energy, and I need sweet things, preferably cookies, to regain my energy so you can transform again. Questions?"
To her surprise, Tikki saw Hayami writing down notes. "I think I got it. I don't think I can be a superhero, but I'll do whatever it takes to save people."
The information was rushing around in Hayami's head. There could be nothing seen in the TV because all the cameras had been destroyed, but she could hear the chaos outside.
"That means you have potential to be a great superhero, but we'll talk about it later," Tikki said encouragingly.
Hayami put the black earrings on. Her voice a bit shaky, she said, "Tikki, spots on!"
Pieces of concrete fell down, nearly hitting Chiba. He could feel his leg getting numb and was reminded of that movie he once saw about a man cutting his arm off in order to survive when his arm was trapped.
He wasn't sure if he was going to live. He could only hope that his sister was safe.
"So, that's the thing?" Ladybug, or Hayami in transformed form, muttered as she scanned the area on a rooftop.
She knew if she could find and break the akumatized item, everything would be fine.
Ladybug threw out her yoyo and it bounced off a wall, nearly hitting herself.
Well, that was a good start, Ladybug thought.
After realizing that she needed some practice in order to face the akuma, Ladybug decided to save the civilians first. Tossing away debris, she freed people trapped under them.
Chiba saw a girl around his age in a tight fitting suit, which was red with black polka dots. She wore a mask and dashed around, saving people. Was she a superhero, saving them from monsters?
Chiba saw the girl lift the piece of debris his leg was stuck in. "Thank you," he replied, a bit slowly because his mind hadn't caught up with the current events.
The girl gave a nod of her head to indicate she had heard him, and sped away, peach coloured pigtails flying behind her.
Chiba looked down at his freed leg and grimaced. It was a purplish colour and it still felt numb. Using his good leg, he hopped to a place where he hoped was safe, and waited.
Ladybug hopped on top of a half-destroyed building. She looked at Freefeather, and saw a black pendant it wore around its neck. When Ladybug looked closer she could see the faint shape of a feather.
That must be what was making it go crazy, Ladybug thought.
She swung her way to Freefeather, and in a daring motion, she landed on top of it.
"Squaw, squaw! Get off me!" Freefeather shook its body and Ladybug nearly tumbled off, but she wrapped her arms around it to keep herself steady. She tried to get the pendant but her hands missed.
Freefeather soared to the sky, Ladybug still clinging on him.
I knew a new ladybug miraculous holder will appear. Quick, get her earrings! A purple outlined mask appeared on Freefeather's face as it heard the voice talking. "Yes Kochou-sama," Freefeather seethed.
Oh no, Ladybug looked down and saw the city moving farther and farther away. She flung her yoyo out and it caught onto a pipe, and then she swung herself to the ground, landing shakily.
"Lucky Charm!" Ladybug said, a bit out of breath. "What is this- a fishing rod?"
Ladybug looked at the red-and-black rod in her hands, then at the pendant. She quickly thought of a plan when she looked at her surroundings.
Ladybug leapt on top of a building and stood there, as if waiting for the akuma. Freefeather noticed her and flew at her with an angry squawk. Soon she had lured it into a building site and Freefeather's legs were stuck in the softened concrete.
Ladybug perched on a pile of materials nearby. As the akuma struggled to free itself, Ladybug stretched out the rod, hooked the pendant and lifted it up. Ladybug stepped on the pendant and broke it, and a black butterfly flew out, which Ladybug assumed was the akuma.
"Um. Cleanse the akuma." Ladybug muttered, while waving her yoyo. She hadn't been given specific instructions but she hoped she could do her job the same.
To her amazement the yoyo caught the akuma and it shone. After a few seconds, a white, purified butterfly flew out.
Ladybug threw the fishing rod in the air and said quietly, "Miraculous Ladybug." She wasn't one to make big appearances.
The rod exploded into dozens of ladybugs and they swarmed through the area, repairing everything.
Chiba saw glowing ladybugs heading towards him. Scared, he tried to move away but his bad leg forbade him from moving quickly. The ladybugs surrounded him and his leg healed on his own.
Ladybug looked at the ladybugs restoring things to what they were before with a small smile. She was about to call it a day when she saw a small child crying.
"Is there anything I can do to help?" Ladybug asked after she walked to the child.
The child sniffed as tears poured from her eyes. "My brother had gotten stuck. I don't know where he is. C-can you help me find him?"
"Of course." Ladybug heard a beep from her earrings. That must be indicating she didn't have much time left. She picked the girl up with superhuman strength and leapt across the streets to find the girl's brother.
"What does he look like?" Ladybug's green eyes scanned the area.
"Oniichan is tall. He also doesn't have any eyes." The girl replied innocently.
Ladybug blinked. She wouldn't try to understand the mind of a kid. Besides, how can anyone not have any eyes?
"Hold on," she said to the girl. She jumped onto the rooftops to get a better view. A lone figure caught her eye. He had black hair, bangs which covered his eyes and he wore a beanie. He looked around her age.
"Is that him?" Ladybug asked.
"Yes! Oniisan!" The girl called. Ladybug jumped down and set the girl on the ground.
Chiba turned to see the superhero girl next to his sister. "Minori!" He ran over to her and would have tripped, but Ladybug caught his arm.
"Are you okay?" She asked.
"Just a bit unused to my leg being fine again." Chiba looked into the girl's bright green eyes, which were intensely staring at him. "And thanks for saving me just now."
He looks familiar… do I know him?
"Thank you for helping me find oniichan." Minori said to Ladybug. "Oneechan, are you a superhero?"
"Kind of." Ladybug replied. She could see the news crew and the camera lens flashing as they located her. She groaned internally; she wasn't ready to deal with people.
"Do you have a name?" Chiba asked.
Ladybug heard another beep from her earrings. She prepared to set off, but she looked back at Chiba.
"Call me Ladybug."
And then she was gone.
On Monday, when Hayami returned to school, the corridors were buzzing with excitement.
"Look look Rinka-chan!" Nakamura, her friend, shoved her phone under Hayami's nose. "I got a picture of the new superhero!"
Hayami looked at the blurry picture of her alter ego. "I'm a bit more concerned about the new monsters though."
"Well yeah, but if superheroes also appear, we'll be alright." Nakamura said optimistically.
Not when said superhero isn't sure if she can be a superhero, Hayami thought. After her fight with the akuma, she had a talk with Tikki. The conclusion of that talk was Hayami would try to be a superhero and Tikki had faith in her. So now the ladybug kwami was hidden in her schoolbag. There were also a few packs of cookies inside in case Tikki needed food.
"I've got to go! Bye!" Nakamura waved and skipped into the next classroom. Hayami entered hers. Everybody also looked like they were talking about the new superhero.
"Hey Chiba, does this look like her?" A grey haired boy pushed a sketchbook to the boy sitting in front of him.
Chiba turned and looked at the drawing. "Accurate enough, Sugaya."
"Did you catch her name? She saved you, y'know."
"No." Chiba said, surprisingly. "I don't know her name."
From her short words, Chiba could already feel that the girl- Ladybug was a serious person. He could see she wasn't very comfortable around people she had just met (aka. him) and she ran away when she saw cameras. He didn't want to expose her, and so he let her do the introductions when she wanted to.
Hayami recognized Chiba as her classmate. No wonder he looked familiar. He's in my class.
"Wait, so an incredibly beautiful and sexy girl saved you a few days ago?!" A bald headed boy joined in the conversation.
Hayami felt disgusted by the perverted look on the Okajima's face. A year spent with him was bad enough, and he had to be in the same class as her too. She turned away and started to read her notes.
"Well, I won't call her that." Chiba was uncomfortable that people were actually talking to him.
"So what's your impression of her?"
Chiba also took out his notes and hid his face behind them. "I am not answering any more questions."
Okajima looked around and saw Hayami doing the same thing as Chiba. He suddenly realized the two seemed to be very similar.
"Umm, Hayami-san, can you please do my part of the project?" A timid girl asked Hayami.
Hayami agreed readily, while wondering how to balance her academic life, her peers' academic life, and her superhero life.
When Chiba returned home, he saw a jewelry box on his desk. Maybe it was some sort of gift for one of his sisters, and it was mistakenly put in his room.
But somehow he was drawn to that box, as if there was an invisible force pulling him in. Chiba slowly opened it, his (hidden) eyes widening when he saw what was inside…
"I'm sorry but no."
Plagg, that cat kwami, scowled when he saw his chosen's reluctance. He was nibbling on a chunk of cheese Chiba had found in the fridge.
"Listen here boy, you definitely have a nice heart. You just need to be more open, and being a superhero is the perfect chance!"
Chiba didn't reply.
"And you won't be alone. You have Ladybug as your partner. And she's probably as quiet as you are. Wow, a quiet duo of Ladybug and Black Cat. Never seen before."
"How do you know so much?" Chiba asked suspiciously.
Plagg waved his hand dismissively. "I'm a god. I know these things. I've watched over generations of superheroes. And this cheese sucks."
Chiba glanced at the kwami irritably. "This is the best I've got. Stop complaining."
Plagg explained the cat miraculous powers to Chiba, in hopes of him getting him interested in being a superhero. After a while it seemed like it did work as Chiba cautiously slid the cat miraculous, a ring, on his finger.
"Now yell, 'Plagg, claws out!'" Plagg instructed. I'm no Tikki, Plagg thought. I'm not good at encouraging people like she is.
"Plagg, claws out!"
In a flash of green light Chiba transformed into Black Cat. He looked into a mirror to see what he looked like, and got a big shock.
His normally hidden eyes were now revealed and he wore a pitch black mask. His bangs had been swept away and his hair was more spiky. Two black cat ears rested on top of his head.
Embarrassed, Black Cat immediately covered his red eyes with his hand. After a while he gradually put his hand away, and looked at the black leather suit he was wearing. Then he tried his best to flatten his bangs again, but they remained the same.
He detransformed and Plagg landed on his bed, a smirk on his face. "So?"
Chiba placed a hand on his bangs, which were covering his eyes again. "Uh… can you make it cover my eyes?"
Plagg groaned, flew to Chiba and flipped his bangs away. "Well they are creepy," he admitted. "I can change aspects of your outfit- for a price."
Ten minutes later Chiba found himself in a store, buying the biggest piece of Camembert cheese he could find.
Plagg munched happily on it. After his energy was restored, he said, "Now transform again."
This time Chiba's bangs remained, except they were a bit shorter. His hair was still a bit spiky. But the most amazing change was his eyes. They were now yellowish-green in colour and wider, and looked a bit like cat eyes.
He was satisfied with the change, and decided to go out to see what his neighbourhood would look like from rooftops.
Hayami was doing a project for someone else when she saw a black figure running on the rooftops. It was her duty as Ladybug to check out suspicious things, and that certainly caught her attention.
Rapidly transforming, Ladybug followed the figure. The person launched himself to the next series of rooftops using a silver baton, which had a paw print on it.
Ladybug swung herself over and the person turned around. That was when Ladybug realized he had the most adorable cat ears on. She sucked in a breath unknowingly.
The boy looked around her age, and his hair stuck out slightly. There was a confused look in his sharp, green, cat-like eyes.
For some reason Ladybug thought he was really cute and wanted to cuddle him and squish his cheeks. It was probably because she loved cats.
This was the first time Ladybug ever saw a boy that she thought was cute.
Then she realized she had been staring at him for some time. The boy's cat ears moved, even more confused. Ladybug had to bit her lip from cooing out aloud. Who was this ridiculously cute boy?
"Is there something wrong?" The (cute) boy asked.
"No." Ladybug said quickly as she felt her whole body go warm. "Are you another superhero?"
"Yes." Black Cat replied shortly. "I'm Black Cat."
"And I'm Ladybug."
"I think we're supposed to be partners."
There was silence as they looked away from each other.
"...I hope we can get along…"
Yeah, that was real smooth, Black Cat scolded himself. Curse his social awkwardness. He held out a hand.
Ladybug smiled. "I hope so too." They shook hands then stood there, not knowing what to do.
"Can you tell me the basics of being a superhero?" Black Cat asked.
"Oh! I'm rather new to this business myself, so let's learn together."
Ladybug was surprised at her eagerness, and her persona suddenly shifted from a cold and aloof one to a welcoming one.
Tikki was right, she thought. This gives me a chance to be more open.
They ran across the rooftops, learning to get used to their outfits and weapons.
It was as if somebody flipped a trigger. In their civilian forms Ladybug and Black Cat had to study, study, and study. As perfectionists they didn't let themselves slack off.
But now they jumped around freely, without a care in the world. Black Cat looked at Ladybug, her hair whipping in the wind. He could see that she looked more comfortable here than when he had first met her in civilian form.
She seems like a nice person. I do hope we get along. Maybe I'll actually make a friend.
