Chapter 2

The helicopter glided through the sky almost effortlessly. Nanoha looked over to Yuuno who had numerous screens surrounding him. As they got closer to Area 46 the helicopter would encounter bumps as if it were going over a speed hump. Nanoha looked at the time and saw they had been travelling for almost an hour. 'How far away is this place?' She thought to herself and as if on cue a rather annoying beeping sound went off and the helicopter stopped moving forward.

"Alright, this is as far as I can take you." Vice called out over the sound of the helicopter. "The magical waves were detected from the planet to the right of us."

The back part of the helicopter opened up giving Nanoha and Yuuno a clear view of where they needed to go. Off to the right was a blue-ish purple planet with a pattern on it similar to tree bark.

"Thanks Vice-kun." Nanoha and Yuuno said simultaneously as they neared the edge and jumped off.

Nanoha and Yuuno equipped their barrier jackets as they descended. Giving Vice a thumbs up, the helicopter turned around and made its way back while the pair headed in the opposite direction towards the planet. Yuuno had a map up on a screen to his left showing where the last magical wave was detected. There was thick fog surrounding them making it hard to see more than a few meters ahead and it gave the planet an eerie feel to it and to add to it, there were trees that blocked out any sunlight.

Yuuno sent the data that he gathered to Nanoha. "All the magical waves detected came from the east." He informed the brunette.

"Say Yuuno-kun, can you come with me?"

Yuuno saw the scared look flicker in Nanoha eyes. There was something about the place that sent chills down his spine. After Yuuno giving her a nod, Nanoha held raising heart out in front of her as they trekked through the fog. As they walked further and further the fog seemed to get worst until they were blindly walking guided by the faint light of the map. Nanoha held onto Yuuno's hand tightly afraid to get separated. They were led to open field. To their surprise the fog let up considerably allowing them the view the area around them clearly for the first time since arriving. Yuuno mentally took note of everything around him to record later when a small light caught his eye. Before he could process what it was a small blade came at him. He dodged it instinctively but then realised Nanoha was standing directly behind him.

"Protection." A female robot like voice said.

A pink barrier came up around Nanoha protecting her from the blade which shattered upon impact. The brunette turned around to face Yuuno, unaware of what just happened. Seeing Yuuno's shocked expression and the shield around her she raised a brow in confusion. Yuuno just sighed at his friend's oblivious state. The blonde stayed on high alert while Nanoha continued to stare at their surroundings.

"Look over there," Nanoha said pointing to something hanging out of a nearby tree. She walked over to it picking up the small pointy object. "Ne, Yuuno-kun, what's this?"

Yuuno's eyes widened at the sight of the thing Nanoha was holding. The object was shaped like the head of an arrow. It was long and slender coming to a point at one end. There was a red string attached to the bottom which appeared to be torn. Yuuno took it in his own hands, looking at it closer and taking in all the little details, on the side was the word 'Revenge'.

It was very much like the blade he saw before. He was about to hand it back to Nanoha when it started to glow. The light it was emitting was blinding affecting their vision. The air pressure around them grew making it hard to stand. The blinding light eventually died down and the blade had disappeared.

The sound of steel cutting through the air broke the silence. Yuuno and Nanoha had barely any time to react when blades came towards them. Nanoha put up her shield blocking the daggers from hurting them but as they came in contact with the shield they exploded causing the brunette to stumble backwards. Nanoha spotted a dark figure jump around in the tree tops and instantly took off after them.

Before Yuuno could go after Nanoha, a monitor came up with a very worried looking Hayate.

"Yuuno-kun? Yuuno-kun you alright? HQ detected the magical waves coming from where you where and-"

"I think we found the cause of it, and we aren't alone." Yuuno cut in.

Hayate looked dumbfounded. They did a check earlier making sure there were no other signs of life. "Really? But we checked and found nothing. By the way where's Nanoha-chan? Is she safe?" Hayate asked realising that she couldn't see the brunette.

"Yeah uh, I think she saw something and took off after it." He stated rubbing the back of his head.

"What?! Yuuno why are you standing there, go after her! Make sure she's alright."

"Yes ma'am."

By the time he finished talking to Hayate, Nanoha was long gone.

"Jeez, slow down will you." Nanoha panted as she called out to the mysterious person in front of her.

From where she was she couldn't tell what they looked like but they were dressed in a simple black overall, similar to what a ninja would wear and a mask covering their face. The said person was jumping from branch to branch and Nanoha was right behind them. They moved swiftly, putting more and more distance between them and Yuuno. Nanoha would get within an arm reach of the mysterious person only to have them speed up more. The mad cat and mouse game they were playing stopped when the brunette stepped on a slightly weaker branch causing it to snap and break. Nanoha landed with a loud thud that echoed around them and to her surprise the other person stopped.

"I am Kuroko." Their voice was cold and harsh as they looked down at the brunette laying on the ground. "I've been waiting for you to arrive, Nanoha."

Nanoha was taken aback. She never heard of anyone called Kuroko. "Who? How do you know my name?"

"My dear Nanoha, You have no clue how long I've waited for you." The mystery person removed the mask and revealed their face but still the brunette didn't recognise them. "I see you have forgotten. I must say, I'm a little hurt Nanoha." Seeing the still confusion look on her face he started to get angry. "Does the name Jail Scaglietti mean anything to you?" he spat out.

Nanoha took a closer look at the man. He had light purple hair and had piercing gold eyes. "But how, you can't be, we had you locked away, far away from here, from anyone after you tried killing everyone and breaking out your father from his cell." She stammered out finally realising who he was.

"Oh the cell you put in me? That could barely keep a rat from escaping. I left there in search of you, you ruined my father's plans, you and your stupid friends. I want my revenge Nanoha. After you put my father in there he slowly lost his mind and went crazy. You destroyed his life and now I'm here to do the same to you."

"Nanohaaaa? Where are you?" a voice called out.

Kuroko gave Nanoha a sly grin. "I'm going to make sure you know how I felt, starting by killing that ferret friend of yours." He taunted before putting his mask back on and heading for the direction the voice came from.

Hurrying to her feet, Nanoha got up and went after Kuroko.

"Nanoha?" Yuuno was cut off by a flying blade narrowly missing his face. "What the-"

"Yuuno-kun! Get away!" Nanoha shouted as she reached the blonde. "Cross fire shoot!"

She flew as fast as she could to get to Yuuno before Kuroko did and fortunately she did. She attacked Kuroko knocking his mask off. Yuuno felt his mouth drop open when he saw Kuroko Scaglietti, Jail Scaglietti's son in front of him.

"Nanoha, what's going on? Why is he here?" Yuuno asked only to be cut off again by more daggers coming his way.

Nanoha and Kuroko fought head on. Nanoha was making it extremely hard for purple haired male to get to Yuuno. As Kuroko pushed forward he was forcing Nanoha and Yuuno to retreat back to the open field. Holding out the blades in between his fingers he sent them flying towards the brunette. Nanoha stood her ground but winced when a dagger skimmed the sleeve of her barrier jacket. Having no time to attend to the minor wound another blade came towards her and cut her on the leg. Yuuno stood behind Nanoha trying to help her in any way that he could.

Once they were in the middle of the open area, Kuroko let out another sly grin "AMF activate." he commanded. A purple magic circle covered the ground. "Like it? I made it myself. It's very similar to an AMF but this one is specially designed for a certain mage." He informed the two.

With an AMF around them Nanoha knew it wouldn't be long until her magic ran out. Flying high into the sky hoping to escape the death trap she entered. Kuroko flew up after her while Yuuno stayed on the ground. 'I really need to practise more, letting a simple AMF get the better of me…' he thought to himself as he sat down and looked up at the sky.

Yuuno tried to contact Hayate the base while Nanoha was keeping the enemy busy but couldn't get a signal. He looked at another monitor showing that the magical waves detected matched with Kuroko's magical signature, he was relieved they found the cause for the mission. He walked over to the edge of the field and stuck his hand out only to be painfully electrocuted. Not only was the magic circle acting like an AMF would but it was blocking their contact with anything outside the barrier and also making it impossible for them to leave. Yuuno looked upwards to see a clash of purple and pink in the sky.

Fighting in the sky gave Nanoha an advantage. She wasn't called the Ace of Aces for nothing but as she continued to counter and attack Kuroko, her magic considerably dropped. She was running out of magic fast and Kuroko knew it.

"Worn out already?" Kuroko mused as he looked at the brunette who was breathing heavily.

No matter how high in the sky they went, Nanoha couldn't escape the draining affects the AMF was having on her body. With every attack she used, they were getting more tiring and weaker.

Back at base Hayate was trying to calm a panicking Fate.

"Hayate?! Did you contact them? Are they okay? Where's Nanoha? Hayate?!" Fate screamed at the shorter girl.

"Fate-chan, calm down okay? You yelling isn't helping." Hayate answer coolly. "Shari-san, have you found anything?" she asked turning to the woman to her right.

"There's a barrier blocking the communication and high levels of magic coming from inside."

Fate sighed out in frustration and was about to charge out of the room and head towards Nanoha, when Hayate caught her by the arm and pulled her back.

"Fate-chan… you can't interfere. You might make it worse going there. Stay put and believe in them." Hayate said sternly.

The blonde sighed. Her friend was in trouble and she couldn't go and help her. 'Nanoha, please be okay.'

Nanoha groaned. Kuroko had punched her right in the gut making the brunette fall and crashed into a nearby tree, leaning heavily on raising heart, she trying to catch her breath before taking off again. As the two continued their battle she noticed that she was the only one getting whacked around and Kuroko wasn't even breaking a sweat. He seemed to have an infinite amount of blades. She flew around frantically trying not to get hit but her effort seemed to be in vain. She had cuts all over her body and her barrier jacket was holding on by mere threads.

"Nanoha… you okay?" Yuuno talked to her telepathically.

"Yeah, just a little worn out. Can you find some way to disable the barrier?" she said back. From where Yuuno was standing he didn't see all the cuts that covered her body.

The blonde male set to work. He had several monitors surrounding him trying to find a way to deactivate the barrier they were trapped inside. "Nanoha, the barrier can only be destroy from the inside, something with a massive destructive power could break it, something like-"

"…Starlight breaker." She finished.

"Can you do it? I mean I can always see if there is any other way."

"No, I'm fine. Could you use a bind to hold him still while I charge starlight?"

Yuuno started to fly up towards Kuroko and Nanoha to see that they were still locked in a fierce battle. As the blonde got closer he saw all the cuts and bruises on Nanoha's body while Kuroko was still in perfect condition. Shaking his head to stop him from getting distracted, he snuck up behind Kuroko.

"Struggle Bind!"

Once Kuroko was secure, Nanoha backed up and started to charge up Starlight Breaker. She had already used up more than enough magical power and firing Starlight Breaker would only decrease that little amount of magic she had left in her. Despite this, she knew what she had to do. Pointing Raising Heart towards the sky she started collecting the magic that surrounded them. "Starlight…" she started but stopped when she felt a sharp pain go through her left shoulder. Ignoring the pain rushing through her body she continued with the task at hand. "…Breaker!"

A pink beam cut through the sky, shattering the barrier around them. The magic circle below them slowly faded away and Yuuno and Nanoha could feel the pressure from the AMF wear away too. Nanoha started to go back to where Kuroko and Yuuno where when she felt the sharp pain in her shoulder again. Looking down she saw blood soaking through her barrier jacket and a blade buried deep inside. Closing her eyes tightly she slowly moved her hand to the blade and yanked it out as more blood flowed out. Having being stabbed in the shoulder wasn't too bad to the brunette since she had experienced worst but that doesn't mean it didn't hurt.

Nanoha looked over too Yuuno and Kuroko and saw that Yuuno needed help. Kuroko had broken out of the bind and threw the blonde male towards the ground knocking him unconscious. Nanoha's eyes met with Kuroko's. He sent her a sly grin sending chills down her spine. He held up a blade and pointed it towards Yuuno before sending it flying.

"Yuuno-kun!" Nanoha yelled as she raced towards the blonde. Only just managing to reach the blonde with barely enough time to put a shield around them. More blades came down crashing against the shield. "Yuuno-kun, wake up!" she pleaded. With every blade hitting the shield it was harder to keep it standing.

The blonde male slowly opened his eyes feeling a cold wet liquid fall onto his face. Wiping his face he saw blood but when he tried to see where it came from, he saw that it wasn't his blood on his hand, it was Nanoha's. "Nanoha?!" was all he could say before getting knocked over again.

Nanoha had been stopping blade after blade from injuring them but with her lack of magical power and her injured shoulder she let one through. The brunette cried out in pain and as it dug into the right side of her hip and knocking her backwards into Yuuno. She felt arms wrap around her stopping her from hitting the ground. Closing her eyes tightly trying to overcome the pain, she heard in the distance laughing.

"Ha! I guess there are some things the Ace of Ace's can't handle!" Kuroko mocked from the sky.

Nanoha went to stand up but fell down again. Every part of her body was in screaming out in pain. "Nanoha…You need to stop. Let's just hide somewhere until help comes?" Yuuno spoke gently.

"No…I can do it…just help me up."

Yuuno slowly helped the brunette to her feet. Her vision was blurring and she could feel her body starting to sway. Squinting slightly to stop herself from seeing multiple, she lifted raising heart towards the sky and at Kuroko. Using everything she had left she charged up another Starlight Breaker but stopped when she felt a dagger come in contact with her left upper thigh. The pink magic circle forming underneath her started to fade.

"My master, are you okay?" Raising heart said. It had small cracks all over but was still intact.

"Yeah, can you handle it one last time?" Nanoha asked her device.

"As long as my master is fine, I am too." It replied.

"Okay let's do it! Starlight…Breaker!"

The pink beam headed straight for Kuroko. The said male was surprised that Nanoha could still produce that much destructive power. Underestimating the brunette was a bad thing to do. Kuroko sent his blades straight into the beam but they disintegrated upon contact. Eyes wide at the sight of his precious blades being destroyed like it was nothing more than a mere speck of dust Kuroko was about to burst with anger. Something was about to burst alright, but it wasn't going to be anger. Seconds after destroying the blades the pink beam surrounded him, ripping his body apart.

Kuroko fell landing a few meters away from Nanoha and Yuuno. His body was smoking from the attack and had massive gashes all over. "You'll pay for this…" he whispered out sending one last blade towards Nanoha.

Too weak to stop it, Nanoha felt it tear into her chest. No longer having to strength to stand she collapsed. Yuuno ran to her side seeing how badly hurt she was. His usually calm green eyes were wide with fear. Nanoha had multiple stab wounds to her body, one on her left shoulder, another to her left thigh, one to the right side of her hip and the last one just below her ribcage. Her sapphire eyes were cloudy, her skin was pale and her clothes were soaked in blood.

"Hayate! Hayate! Hayate!" he shouted telepathically.

A monitor came up next to him showing the back of the short haired brunette. "Huh what? Yuuno-kun?" she answered not hearing the desperation in his voice.

"Hayate! Get help! Nanoha's been hurt."

Nanoha who was currently lying on the floor sat up slowly and gave a thumbs up towards the monitor trying to object to what Yuuno had just said but fell back down again in pain.

Hearing the groan coming from Nanoha she instantly came to senses. It wasn't often Nanoha was hurt and when she was, it was bad. Luckily for her sent had sent Fate home minutes before. "Someone get Shamal and send her over to where Yuuno-kun and Nanoha-chan are right away!" The office was sent into a panic trying to gather a group of doctors and a way of transport. Minutes later a helicopter was zooming towards Area 46.

"Nanoha… help is coming. Stay with me, don't close your eyes… please Nanoha, just wait a little longer." The blonde begged trying to keep Nanoha from losing consciousness.

Even thought Yuuno was right next to her, Yuuno's voice appeared to be getting further and further away. Her eyes felt heavy as the world around her blurred. Holding Yuuno tightly she whispered something into his chest. "Yuuno-kun, tell Fate-chan I'm sorry, I couldn't keep the promise." Was all she said before falling into darkness.
