Chapter One

A/N: I generally don't put these at the beginning, but I have some important info about this story that I couldn't fit into the description so I'm putting it here. IT IS IMPORTANT THAT YOU READ THIS. The beginning of this story takes place when Stein, Marie, and Spirit are still attending the DWMA as students. It's slightly AU, but it'll make more sense as the story goes on. The story will probably take place in this time period for the first three to five chapters, depending on how long it takes to write out the exposition. Just bear with me a little, okay? Also note that for now, Kid doesn't have the lines of Sanzu in his hair (I get that it doesn't make much sense at the moment, but trust me that it will make sense a little bit later in the story). I am sorry for the really long authors note, and don't plan on writing them in the future. Without further ado, here is The Symmetry of it All.


"You're sure that you want to take on this mission?" Stein raised his eyebrows and crossed his arms over his chest, "Marie and I could go with you. Are you sure that-"

"We can handle it, Stein," the raven haired boy smiled, "Mayu, Mitsu, and I are fully capable of handling it."

Stein smiled inwardly and watched as Death the Kid slid the working tag around a panel on the mission board before heading down the hallway. He was joined by his two partners as he walked.

The girls were identical, twin weapons. They walked on either side of him. Not only were they identical in looks, but they were also identical in their outfits as well as their weapon forms. Their short layers of dark brown hair were held pinned back by cream colored head bands. The two of them had big, brown eyes that would remind anyone of a puppy dog. They wore long-sleeved black button downs with cream colored ties and short cream skirts with a lace hem. They wore a pair of black leggings along with black ankle-length boots.

They moved to hold hands behind Kid's back.

Stein smiled, "What an intriguing pair of pistols."

The trio continued down the hall.

"He's only a year beneath us, but he's almost just as good," Stein looked at Marie as she came down the hall, "Did you know Kid took on the mission to attack the nest of vampires at the south end of the city?"

"No," she tucked a loose strand of hair behind her ear as she glanced down the hall just as the trio disappeared up the stairs, "Isn't that a bit dangerous?"

"I asked him if he wanted any help, but he said that the three of them could handle it," Stein shifted his books in his hands, "We should get to class, I'm sure Kami and Spirit are already there."


"Mayu, Mitsu," Kid stood just outside the entrance to the vampires' nest, "I'll need you to transform. Try your best not to transform back until the coast is clear. I don't want the two of you getting hurt."

"Alright," they said in sync before flipping into the air and landing into his hands at the same time. The pair of midnight pistols gleamed in the light of the moon. Kid spun them easily in his hands before exhaling.

This is all natural. We are untied as one unit. Two weapons being wielded by a single meister as one. Mayu and Mitsu are two halves of a whole. We are perfectly balanced. We are symmetrical.

Kid opened his eyes. He felt so much more aware with the added sense of perception the twins gave him. He exhaled and approached the entryway to the nest.

The doors swung open. A barrage of hissing came through the door as at least twenty pairs of red eyes turned to fixate on them. Kid exhaled once again before his golden eyes glinted open. Glowing golden shots were fired from the guns.

Blood splattered across the walls, the screams of the creatures bouncing around the nest. Kid didn't even flinch when blood splattered across his face and clothes.

The creatures came close, but none of them laid a finger on the trio. Within a few moments, twenty red souls were hovering around the dark room.

"Clear," the twins spoke into his mind at the same time before transforming back. Kid sat his hands in his pockets and watched as the two absorbed ten souls each. Mitsu turned to look at Kid first, walking up to him. She furrowed her brows together as she attempted to wipe the smear of blood off his cheek with his thumb, "You're all dirty now."

"Is that all?" Mayu raised her brows, "That wasn't even that hard."

"Should we head home now, Kid-kun?" Mitsu tipped her head to the side.

"Sure," Kid smiled, "We'll head back and be ready bright and early for school tomorrow."


"How did it go?"

"It went well," Kid watched as Mitsu straightened one of the books in the stack on her desk, "The twins already want to take on another mission."

"They're…" Stein looked past his classmate to look at them, "Very interesting."

"A bit OCD if you ask me," Kid chuckled to himself, "They changed all of my clothes to be symmetrical. They say it makes the form look better. Usually I'd protest, but they're very good weapons."

"I'd noticed the change," Marie smiled, "It looks very nice."

"They seem to think so," he glanced back over at them, "My father believes they will be excellent death scythes."

"I'm sure they will be," Marie giggled.


That night they'd gone to bed early. Kid was in his bed upstairs, curled in a tangle of black sheets, sleeping soundly. Mayu and Mitsu were in their room across the hall. The two slept side by side in a big bed at the center of the room. They mirrored each other, their hands lying in a clasped knot between the two of them.

Suddenly, Mayu's eyes flew open and she sat up. A draft from the window blew in the curtains. She blinked and rubbed her eyes, "Mitsu," she shook her sister's shoulder, "Mitsu, did you leave the window open?"

Mitsu made no movement. She didn't even acknowledge her sister. Mayu sat up further in the bed, "Mitsu," she shook her sister's shoulder once again, "Mitsu, wake up."

Again, Mitsu made no movements or even an effort to move. She didn't even look like she was breathing. Mayu pulled back the white sheets and let out a scream.

Kid jolted awake in his bed. We was up and moving in an instant. He threw open the door to the twins room and tensed in the door.

The white sheets were stained dark shades of crimson. Mitsu lay lifeless on the bed, red seeping from her stomach, through her cream-colored night dress. A pair of puncture wounds in her neck spilt more blood onto the sheets. Her brown eyes were still open, but cold and distant; almost as if she were staring at something far away. Mayu's hands were shaking. Kid looked from his partners to the open window where a dark figure with glowing red eyes stood. Kid clenched his fists, "Mayu, transform."

Mayu was shaking. She looked from her sister's corpse to her meister. The figure stepped closer. Kid felt adrenaline begging to pump in his Shinigami veins, "Mayu!" he barked, "I know this is hard but I need you to transform!"

She let out a breath, but did what she was told. Kid caught hold of the pistol in both hands. He fired a few golden shots, but the figure disappeared out the window before any of them could reach him.

The moment the figure was gone, Mayu transformed back. She knelt at her lifeless sister's bedside. Tears flowed from her eyes, her entire body convulsing with sobs. Kid came to kneel beside her. He didn't need to check Mitsu for a pulse to know that she was gone.

He brushed his fingers over her face, closing her eyes. He kissed her forehead before standing up.

"What are we going to do?" Mayu sniffled, "Mitsu…"

Kid turned to lean against the doorframe. He felt sick. He was sure he had never felt this sick before, not even when he'd had the stomach flu late last year. Sweat prickled at the back of his neck.

Mayu sniffled a bit more, "Kid-Kun? What are we going to do?"

He glanced over his shoulder at her, "I-I'm not sure, Mayu." He turned away from the twins once more; the sight of Mitsu's body was too much to bear. He stepped away and walked back into his bedroom, leaning against the wall. He needed to call his father. His father would know what to do.
