Chapter 1: Death the Girl / The Balance Meister

"52, 53, 54..."

"Not bad, Fyre." Athena sat by her weapon partner. "But can your pushups take a rain check? I've located our next soul."

"If you insist." Fyre sat on his knees and Athena wiggled next to him. She then flipped open her laptop and displayed a picture.

"Stockholm, Sweden." He read out loud.

"Yes, that's where we're headed. But look at the details of the woman he murdered. A 32-year old unidentified prostitute was found dead around 48 hours after her death. She was killed by a strong blow to the back of her head, and when they checked the autopsy, they noticed he was drinking her blood."

"That's why they called it the 'Atlas Vampire Case', is it?"

"Congratulations Captain Obvious, you've done it again!" Athena smacked her thighs with sarcasm.

"Okay, okay, that's enough." He pouted. "When are we leaving?"

"I managed to get us tickets together for tomorrow morning's flight."

"Great. I'll pack then." Fyre stood and she closed her laptop. "Does your dad know we're leaving so soon? And what about your brother? It is our turn to do dishes tomorrow."

"My father does- but I suppose Kid should probably be warned." Athena stood as well, and tucking her laptop under her arm she walked to go break the news to her little brother.

XOXOXO

"Pass me the damn peanuts- oh, Athena look! We're in Sweden!"

"Wow, Fyre. Imagine that. The plane ended up where we wanted to go. Someone must have planned this! I demand an answer!"

He rolled his eyes with a smile. "Haha, very funny."

"Well, you are smiling." She poked his cheek.

Close to an hour and a half later, the two of them where flying through the sky on Athena's skateboard, Kalphozan.

"Do you sense anything?" Fyre asked in his weapon form, a semiautomatic rifle.

"I've been sensing his soul since we landed. A soul like his is impossible to miss." She murmured and landed. "He's up ahead-" she suddenly froze.

"What is it?"

"I've lost trace of his soul. He was here ten seconds ago..."

"Athena! Behind you!" Sidestepping quickly, a baseball bat hit the ground where she had just been standing.

"Shit. Thanks. I'm supposed to be able to catch shit like that before it happens." She turned to look at the kishin, who was swinging his baseball bat as he moved closer.

"Athena?"

"Mmhm."

"Let's go soul resonance!"

"The deadliest technique known to reapers... Madness of Orders!"

Fyre shifted in her hands, into a larger, darker gun with an image of Lord Death's mask on the side.

"For your murder of an innocent human being, I will take your soul. Atlas murderer- you have become a kishin, and now your soul is mine!" At that, the kishin lunged forward. He attempted to knock her over by swiping at her feet, but she jumped up over it and shot a compressed soul bullet into his shoulder.

He roared in pain and lunged again.

"What an idiot. He keeps on trying the same thing expecting it to work each time." Fyre commented.

"Well, I didn't exactly expect him to be fresh out of school." Athena replied. "Unlike you, I always expect the kishin are idiots, and I'm always right." She fired another round into his other shoulder. "I mean, he sucked his victims blood."

"He's a special little snowflake, isn't he?"

Loosing his patience, the kishin threw his baseball bat to the side and tackled Athena, forcing her to the ground. She had no time to react, and dropped her weapon in shock.

"Athena!" He started to transform back.

"I got this!" She yelled back, holding his long teeth away from her throat with her hands and pushing his body away with her knees. "Stay there! I'll grab you in a minute!"

"If you're sure-"

"We used to fight witches. I can handle a little kishin." She used all her strength and rolled so she was on top, and then kicked off his stomach to land next to Fyre.

"Nice!" He commented.

The winded kishin attempted to stand, but Athena kicked him back to the floor. Placing the barrel of the gun against his head, she fired and a single blue would remain.

"This totally makes up for the peanuts you wouldn't let me eat on the plane."

"I wanted you to save room." She told him as he ate it. "What if you were full? I wasn't going to carry that around for you."

"Your phone is flashing." Fyre pointed out.

"Kid texted me. What on earth could that little brat want- are you kidding me?"

"What is it Athena?"

"Father wants us back to the death room ASAP because he has another job for us."

"Good lord, he does realize we have things to do, right? We don't just sit around waiting for jobs all day." Fyre sighed.

"Apparently not. Let's go back to the hotel room, I guess... I'm tired." She stretched. "But what on earth could he need so urgently?"

XOXOXOXOXO

"Kinkou! Swipe coming in from the left!"

"There's a beam on the right!"

A young woman, perhaps 16, back flipped away from two kishin eggs, one being a monstrous distorted human with a dagger, and another that blasted its soul wavelength in the form of beams. She was able to dodge both, and panted a little, looking at the two blades in her hand, a white sword in her right, and a black one in her left. On the hilts connecting to the blade, there were eyes on either side of each sword.

"I think its time we used Dark ballad," The black sword said positively, and the white sword vibrated. "No way! Do you want to hurt Kinkou?" The white sword just about shouted at the black one, while their Meister, Kinkou, used both of them to block a few slashes from the dagger, and she made a wincing noise. "… We need to use it Hikari" Kinkou murmured. "I know you don't like it, but we need to…"

The white sword stopped her shaking. "Are you sure you can stand it?"

Kinkou gave a small, gentle nod, and there came an audible sigh from her white sword, Hikari. "Alright… Kira, I swear, if you knock Kinkou out again…"

The black sword, Kira, made a snorting like sound. "Its always you not balancing right"

"Yeah well-"

"I-I cant…. Resonate if you argue" Kinkou said as she parried to the right to avoid a blast.

"Sorry" The two blades said simply, and Kinkou stood still for a moment, holding the two blades together. Her previously grey eyes turned fully black. "Half Soul Resonance – Dark Ballad!" The two swords became one, longer black sword with a white stripe going down the center. It gained a curved effect, and She held it straight to produce a charge with their soul's resonating with each other. There were some sparks, as Hikari's power was constricted and she had to lower her power. Giving some struggle, Kinkou pulled the combined sisters to her left, and quickly swiped it to her right just as both Kishins were about to pounce her.

The energy collected created a large black wave of soul wavelength, coming mostly from Kira. It cut cleanly through both Kishins, efficiently killing them somehow. Two kishin egg souls floated down to the floor, and before Kinkou could wind down, the twin swords separated on their own, and transformed to their human forms. Kira was black haired with black eyes, and she wore combat boots over her black skinny jeans, then a black shirt with the "Gemini" sign on it in white. Hikari however was nicer dressed, wearing white Mary Jane style shoes with black knee high socks, a beige pleated skirt, white button shirt, and a white jacket to cover it. Her hair was also white, and one could almost not tell her eyes had a color at all, for they were white. The two both ran to get their souls, and Kinkou sat on the floor. She wore an even mix of black and white, and her hair was dark grey and her eyes were lighter. She wore black boots with a black skirt, a white button shirt and a grey sweater vest, combining a part of both her swords wardrobe.

With their souls consumed, they returned to their Meister and Hikari helped her up. "Are you okay, Kinkou?" She asked.

The younger moister nodded. "I'm okay," she said quietly and softly, but Hikari frowned. "… Lets get home. You need the rest"

Kira walked over then yawned. "I'm hella tired too~"

"This isn't about you, its about Kinkou" Hikari said slightly bitterly. "You know how much strain it takes for her to balance it"

"I'm fine… really," Kinkou muttered, though she leaned on the light twin. Hikari frowned and supported her younger Meister, and Kira just gave a slight frown. "I'm sorry Kinkou…

"I'm okay," she muttered again, this time with more annoyance in her tone and Kira stepped back. "Whoa, 0 to 100 real quick" Kira chuckled, and Kinkou looked down, embarrassed.

"Sorry" Kira muttered and the trio walked home with one another.

XOXOXO

Before class the next day, the two swords were looking at assignments on the board, trying to decide which one would be best for their Meister.

"This one" Kira pointed out, and Hikari looked at it. "It's about two hours away... Maybe, I mean, it's a one star Meister mission..." Hikari muttered. "It should be easy for us... Kinkou won't get hurt" Kira said and Hikari nodded.

Taking the card with them, they left for their class, which was full of the older class, titled Full Moon. Inside was no one except the teacher writing down notes on the board for a warm up and Kinkou in her seat copying them down. She noticed her weapons walk in and gave a soft smile to them. "Good morning" Kinkou greeted quietly, and then continued writing her notes. Her weapons sat down beside her, then Hikari pushed the note to her view. "Do you think we can handle this?" She asked Kinkou studied the card for a few moments then nodded.

"Great!" Kira grinned. "I can't wait for the night to come! This will be so much fun!"

"If we don't have homework" Hikari reasoned with her, and Kira frowned, folding her arms and pouting. "Fiiine"

Kinkou giggled at their banter, and she drew a little on her notepaper. 'Opposites attract, they say' she thought as she drew a heart, coloring in one side black and left the other white. The twin blades brought out their papers and looked at the board as the bell rang. "Eh? Soul Forces? Didn't we study this last year? In Crescent Moon?" Kira sounded confused.

"Sid-Sensei did say that he didn't go as in depth as they would have liked" Hikari replied and Kinkou nodded while other students filed in. After the bell rang and attendance was taken, they were given about five minutes to copy the notes before their teacher cleared her throat. "Students, as I'm sure you've realized, today we will be studying Soul Forces, or attacks that come from using your soul. I want you students to not only review this, but also learn more about it. I want you to physically tune your souls to be able to use this type of attack in case you are left without your weapon or Meister. Today, I will be observing everyone's basic use of the soul force attack. Starting with…" She glanced around the room. "Kinkou"

The Balance Meister lifted her head, apparently drawing something else and having only partially paid attention.

"Come down and show everyone your understanding of the soul force" Her teacher smiled, making a come here motion and Kinkou stood. She went to the front of the room, and their teacher stood guard. "Alright, come at me with everything you have Kinkou, don't hold back"

Kinkou looked at the palm of her hand, then went to a guarding stance too, for a second, it looked as if she was waiting for their teacher to strike. She suddenly pulled her arm back, it becoming cracking in light grey energy, and she rushed forward and did a palm strike to her teacher's stomach. Small soul like particles scattered at first, and her teacher was wide eyed, and they all focused back far too quickly, and the whole of the attack sent her into a wall. All the students gasped, and their teacher coughed up a little bit of blood. "I wasn't even able to block it…" She muttered. "Kinkou, that was outstanding. You may sit"

Hands clasped over her mouth, Kinkou rushed back to her seat and started blushing bright pink in embarrassment. "I didn't hold back," she murmured. "I went full force… but why? She should have blocked it…."

"What the hell Kinkou? That was sick!" Kira grinned.

"She probably needs medical attention" Hikari mumbled.

After their teacher straightened up and wiped the blood from her face, she cleared her throat yet again, swiping some of her blond hair behind her shoulder. "Kira, Hikari, I want you both to come up next"

The twins deadpanned, and then they got up, also going to the front of the room. All the students watched in interest as Kira went forward first, and tried to mimic Kinkou. Her attack wasn't anywhere near as powerful, and their teacher simply skidded back a few inches. She was then hit back with a weak soul force and got sent to the wall. Hikari tried then, and with a different approach of going for a punch. She was also deflected, the teacher skidding back a few more inches and having to regroup her footing, and she flung Hikari to the wall next to her sister.

"I'm disappointed" Their teacher sighed. "After Kinkou practically threw me into the wall, all you two can manage is a few inches?"

A lot of the students laughed, and a cocky young man with a starting goatee laughed the loudest. "What a shitty Meister, taking all the training for herself and not even helping her weapons learn. Guess that's one more thing that Kinkou doesn't have, a sense of helping others" He continued laughing.

"Soul Resonance. Light Ballad"

He stopped laughing, and looked down to see a white blade pressed to his neck spikes protruding from one side and a black stripe down its center. Kira held Hikari in her right hand, her eyes glowing bright white. "Talk shit about our Meister" Kira growled. "And we will let our souls be confiscated just to slaughter your sorry ass"

He suddenly shook at the powerful soul wavelength the two had put off, as did many other Meisters that could see souls, even some who couldn't. Kinkou observed the souls of her weapons. Of course, only they could pull off such a resonance protecting her. She looked at her hand, which had a faint scar on it from consecutive burns. She finished her note pages as her weapons sat back down next to her, the entire class silenced by the twins and the lack there of a reaction from Kinkou.

Their blonde teacher sweat dropped a little, seeing the entire class dead silent, and smoothed out her skirt. "Right… Julian, you're next"

Xoxoxo

"This is the area," Hikari said, looking at the card. She tucked it into a bag as she and Kira transformed. Kinkou kept them low, but sprinted down the streets to get a view of their target. "In class today" Kinkou started off. "Did I just get lucky? Or were you both really that low in power? If so, I'm sorry 'Kinkou said, turning a corner to a new street.

"Don't worry about it, our soul wavelengths aren't as strong as yours" Hikari said softly. "And you're a Meister of great proportions. Don't sweat it one bit"

"Yeah Kinkou" Kira grinned in the reflection of her blade. "Don't worry, that was hella sweet, pwning the teacher like that. She needed to get messed up, I got an D on my last project"

'Probably because you copied off of me" Hikari deadpanned in her reflection.

"Shh" Kinkou murmured, tightening her grip on her swords. They both became silent, and Kinkou peered around a corner she heard noise from. She saw a gangly looking male, and he was slurping down a human soul he had just stolen. Part of his arm was amputated, and it had a table saw fixed onto it that seemed to operate by his soul wavelength. The other hands had blades replaced for his nails. He was taller than a normal man, that was sure.

Kinkou made a hardened expression- the one thing she was half decent at, killing kishin eggs. She put the twins in a holster belt she donned, and climbed up the building, and once on the top, she pulled them both back out, started at a run, and jumped off the roof. "Kishin Egg Sawend Joe! Your time is done!" She stabbed his back with Hikari and Kira, surprising Hikari but otherwise just making Kira cheer. Kinkou back flipped off of her target, and he swung around with his table saw arm, hitting Hikari but otherwise leaving no harm.

"That didn't kill him?!" Kira complained.

"I told you we were going to need a resonance!" Hikari argued.

"Calm down" Kinkou muttered while blocking a swipe from his claws. "We need focus…"

The two silenced themselves in attempt to assist Kinkou, and she brought them together after flipping farther back. "Half Soul Resonance… Light Ballad!"

"What?!" Hikari exclaimed.

"Kinkou no!" Kira shouted back.

"Why not?" Kinkou murmured, unable to pair them as they shouted against her, and due to the interruption, she was swiped from the bottom up, claws tearing her clothes but not her skin, and she was flung back. "Kinkou!" The two weapons exclaimed, alarmed.

"… Now… please…" Kinkou murmured, getting up. "Light ballad!"

The two frowned, but focused and resonated with Kinkou, forming one sword. The appearance was the same as earlier, long and white with a black stripe down the middle, and five long needlepoints coming from one edge. There were many sparks at the hilt, and Kinkou tightened her grip. She pulled the combined Hikari and Kira to the side, and swung it back as the kishin egg was about to attack again. Five bullets like beams shot out from the needlepoints and launched directly into the kishin and exploded inside on contact.

"Fucking bitch! You're taking too much!"

"Stop forcing me away!"

"Damn…" Kinkou murmured, and their resonance fell apart. Feeling taxed, she still ran up and attacked, slicing her swords over the kishin where the bullets went, and as if it had done the trick, the kishin exploded, leaving a red soul in its place.

Kinkou fell to her behind and the Hikari changed first, ran over to the soul before her sister could, and downed it. Kira transformed afterwards and frowned. "Sis, unfair"

"Yes, it is fair" Hikari stuck her tongue out.

"Listen here you-"

"Stop" Kinkou murmured. "I'm injured… cant you see…? Lets hurry up home…"

"Fine… but tomorrow" Kira pulled the card she had been gazing at during the morning and grinned.

"We'll do it tomorrow" Kinkou murmured and stood up with Hikari's help. "I promise"

"Alright!" Kira grinned. "This soul is goanna be mine!"
