A/N: So this has been kinda in my head ever since I finished Madoka. I thought it would translate over well with Tadashi and Hiro plus I wanted to do something heartbreaking. This will most likely be different than Madoka's canon. Since I had to change some things around to suit the characters and the story. But the basic concept is the same. Warning: If you've seen Madoka you know this will not be a happy story.

Disclaimer: I don't own Big Hero 6 or Puella Magi Madoka Magica.

Prologue

It had all gone so wrong. How had it all gone so wrong?

He could only stare in horror as he saw his brother struggle to fight.

Hiro knew he was going to lose, the witch known as Walpurgisnacht was just too strong for one person, and he was going to have to watch.

"There is a way you can save him." The voice of Kyubei resounded in his head.

"How?" Hiro was frantic. He would do anything.

"You can make a contract with me. You already have so much natural talent Hiro. I'm certain you could kill Walpurgisnacht in one hit if you wanted. Come, lets make a contract."

In the distance Hiro heard Tadashi scream something at him but he couldn't make out what it was. He had to save his brother. He had to.

"Okay."

Chapter one

Hiro woke up in a cold sweat.

'Just a bad dream' He thought. It had felt so real. He had tried to recall what it was about but he couldn't remember.

Hiro looked over to what used to be his brothers side of the room. After Tadashi had gotten accepted to college he had moved into a dorm room and Hiro didn't get to see him much anymore. He used to climb into Tadashi's bed whenever he had a nightmare…

Hiro swallowed, his chest tightening. 'Come on Hiro, you're not a kid anymore'

Sighing, Hiro made his way to the bathroom to get ready for school. He was a sophomore in high school and while he didn't mind school he didn't exactly like it either. It was a little easy for him and Hiro often found himself bored.

Having finished getting ready Hiro made his way downstairs to where his aunt Cass was busy making breakfast.

"Mornin' aunt Cass."

His aunt smiled, turning her head slightly to greet him. "Morning Hiro. I hope you're in the mood for pancakes."

"Sure, sounds great."

And just like that, the feeling of dread left over from the nightmare had disappeared with the help of pancakes.

By the time Hiro had finished eating, said goodbye to his aunt, and headed off for school, the events of that morning were completely forgotten.

Hiro was staring out the window. He couldn't explain it, but there was something off about today. A strange melancholy feeling that he couldn't describe.

"Hiro!"

Long thin arms enveloped him in a hug and Hiro laughed, the interruption forcing him out of his reverie.

"Hey Honey. Excitable as always I see." It may have seemed weird for a fifteen year old boy to have a girl as his best and only friend, but to Hiro it was natural. He and Honey had met in chemistry class when they were partnered together. Hiro was surprised that there was someone at the school almost as smart as him and the two quickly bonded. They had been inseparable ever since, having many other classes together.

Honey giggled. "I love mornings, it's always so calming and everything feels so fresh."

"Speak for yourself." Hiro grumbled. He was definitely not a morning person.

At that moment the teacher walked in and Honey quickly made her way to her seat behind Hiro.

Honey and Hiro had plans to hang out after school, they had a big project coming up in chemistry and both were pretty excited to get started on it. They were planning on spending the day brainstorming at Hiro's house.

"Hey Hiro, do you mind if on the way to your house we stop by the comic shop?"

They were walking home from school when Honey spoke up suddenly. Hiro quirked his brows, confused. Honey was not one to put off studying but then he noticed her mannerisms; the way she kept twisting the hem of her shirt in her hands with her head down and a slight blush playing on her face and realization hit him.

Hiro grinned. "Ahhhh I see. A gift for Fred I take it?"

Honey's blush intensified. "Y-yeah."

"Heh, okay then."

Honey could only murmur a small thank you as they made their way to the comic shop, a blush permanently stamped on her face the entire way. She was thankful to Hiro for not teasing her about it though.

'Save me'

Hiro paused, hand raised about to grab the latest issue of Iron Man. Honey was far away still picking out the perfect comic book for Fred and completely absorbed in her own world.

'Save me, please'

There it was again. That voice in his head. He looked around wondering if anyone else noticed but nobody was acting any differently. It was so loud, how could they not here?

'Please…'

The voice became more frantic, pleading. And the hair on Hiro's neck stood up. He didn't know why but he had to go to the voice, he had to find it.

Hiro made his way out of the comic shop in a trance. He couldn't explain it but he just knew where to go. The voice was calling him more frequently now, getting louder and louder until it was the only thing he could hear.

And then he saw it. There on the ground in a seemingly deserted alleyway was a small creature. Hiro couldn't tell what it was but it was bleeding. He quickly ran towards it, desperate to help in anyway.

Gingerly he picked up the creature and noticed it looked like a cross between a cat and a fox. It was pure white with golden rings wrapped around it's ears. Hiro had never seen anything like it, but it had to be alive because it was breathing.

"Get away from that thing."

A cold voice said from behind him and Hiro's blood froze cold. He knew that voice but it was one he hadn't heard in a long time. Hiro gulped and turned around to face him.

"T-tadashi…?"

Hiro was in full blown panic mode now. He hadn't seen his brother in months and now, here he was. Standing over him with the coldest glare Hiro had ever seen and was that….a gun in his hand?

"Get away from that thing Hiro. You don't understand."

"W-why? What are you planning on doing with it?" Hiro hugged the creature closer to him and he noticed his brothers grip tighten on the gun in his hand.

"That's none of your concern. Now let it go."

"Leave him alone!" Honey shouted as she ran towards Tadashi barreling into him and knocking him off balance.

"Hiro! Run!" She shouted at him but he couldn't move, too shocked to do anything.

"Dammit…get off me. Neither of you understand what you're doing." Tadashi grunted out as Honey struggled with him. Honey was much stronger than she looked and Tadashi was having trouble keeping her off of him. But finally, he was able to push her back and Honey fell of her back.

To her horror she noticed that Hiro was still there, staring slack jawed at his brother. She quickly scrambled to her feet and grabbed Hiro by the arm.

"Come on Hiro! That man's going to kill us!" She screamed.

That seemed to knock Hiro out of his trance. "He wouldn't! That's my brother! Honey, I have to talk to him!"

But as much as Hiro struggled he couldn't get out of Honey's death grip on his arm as she led him out of the alleyway.

Suddenly the world seemed to shift and everything seemed to morph into strange shapes and impossible colors.

"W-what…? What happened to the alley? Where is this?" Honey was frantic, growing more panicked by the second.

Hiro was getting panicked too. First his brother, now this…what was going on?

A strange eerie sounding laughter seemed to come from all around them and Hiro and Honey looked up in horror to find menacing looking creatures. They were holding scissors and it was clear they were not friendly.

Honey shielded Hiro with her body, hugging him close to her. The both of them closed their eyes expecting the worst.

The sound of flesh being cut open shocked them both into opening their eyes, the fact that it wasn't their flesh being cut shocked them even more.

A man stood before them. Dressed in bright green armor he had dreadlocks and in his hands were two swords. As soon as he killed the creatures the world seemed to shift and go back to normal. They were back in the alleyway now.

"You two ok?" The man addressed them. He was big but something about him was calming.

"Y-yeah." Honey answered for them.

"Who are you?" Hiro asked and the man opened his mouth to speak but was interrupted by a loud voice.

"Wasabi!" Tadashi shouted, he looked furious. "What are you-"

"I could ask you the same thing Tadashi." The man called Wasabi interrupted. He glared at Tadashi and Tadashi glared right back.

"Trying to kill Kyubei really? What were you thinking?" And then Wasabi's face softened and he moved closer to Tadashi. "Whatever's going on man, we can get through this. Together. Let me help you."

"You can't help!" Tadashi snapped. Hiro had never seen him this, his brother never, ever got mad. But it was clear something had happened to him in the months they had been apart and it broke Hiro's heart to think about.

"Tadashi…" Hiro said and Tadashi's head snapped towards Hiro's direction. For a split second Hiro could've sworn he saw a look of sadness cross Tadashi's face.

Tadashi swallowed hard. "…Forget it, I already failed."

What did that mean? Failed what? Hiro's brain was swimming and he felt like he was going to faint. Nothing made sense and he just wanted to run towards his brother. To hug him and beg him to come home.

Tadashi turned and left the way he had come. Hiro tried calling after him but Tadashi only ignored him and then he was gone. Hiro dropped to his knees and started to cry not even caring that Honey was there and the stranger that saved them. He felt Honey wrap her arms around him and he was grateful for the contact.

He heard footsteps coming towards them. "Uhhh…excuse me," Wasabi was speaking to them and he was clearly at a loss for what to do "but umm…you have my friend there and I need to heal him."

Hiro had completely forgotten that he was still cradling the creature in his arms and he quickly handed it over to Wasabi.

Wasabi took out a small egg shaped object and held it close to the creature. In a moment the creature opened its eyes and hopped out of Wasabi's arms.

'Thank you, Hiro."

"H-huh? How do you know my name?"

The creature swished its tail. 'I've been watching you Hiro. You're very special and I want to make an offer of sorts to you.'

Offer? What did that mean?

"Umm…Hiro? Is it talking to us?" Honey asked her eyes widening.

"You can hear it too?!"

The creature tilted it's head to the side and studied both of them intently. "My name is Kyubei. I am talking to the both of you through telepathy. You see I really only intended to make Hiro an offer but you show promise as well, Honey. Tell me, do you want to make a contract with me?"

"Contract?" Honey asked her voice wary.

"Yes. I can grant any wish you desire and in return all I ask is that you fight those creatures you saw."

Honey and Hiro shared a look. Neither of them were warrior material and fighting those creatures again didn't seem very appealing and yet…both of them couldn't deny the inexplicable draw that Kyubei's offer had.

Wasabi smiled, as if sensing their thoughts on the matter. "It's really not so bad. Kinda scary at first but you get used to it."

"You…made a contract with Kyubei?" Hiro asked.

"Yes. Those creatures you saw? Those are what's known as witches and it's up to me and people like me to stop them. It's your choice but…I could always use allies."

Hiro and Honey considered what Wasabi had said. If Hiro was being honest the thought of being a superhero was appealing but he hadn't the slightest clue what he could wish for. If he was going to make a wish, it had to be something good.

"I have a suggestion." Kyubei spoke up. "Why don't you two go with Wasabi while he fights and then you two can see firsthand what it's like?"

"But isn't that…dangerous?" Honey asked apprehensively.

"Nah. With me there, you guys got nothing to worry about. I think it's a great idea. That way you absolutely know what you're getting into. But like I said it's your choice."

Hiro was deep in thought. He couldn't shake the feeling that this was the way he was going to find his brother again. He had to do this.

"I'll do it."

"Hiro…?" Honey stared at Hiro searching his face to see what he was thinking.

"I have to do it Honey." And Hiro's face was filled with such conviction that Honey understood instantly.

"Well if you are, then I am too."

Wasabi clapped his hands together, a big grin on his face. "Great! We start tomorrow."

Honey and Hiro didn't talk much on the way home. They decided to forgo the brainstorming session today, both of them were too tired to do anything. Besides, Hiro needed to be alone and Honey understood.

As soon as Hiro got home he made his way straight up to his room, ignoring his aunt's questions about how his day was.

As soon as he entered his room and shut the door Hiro sank to the floor. A sob erupted out of him. A sob he didn't know he had been holding and Hiro cried for his brother.

'What happened to you Tadashi?' He kept asking over and over in his head. Silence was his only response.
