~Flashback~
Shikoku was seen walking as she passed by various cages. Each one holding a girl that had devoured a peach. All of them had a soulless look in their eyes. However, as she passed by each of them, she noticed they all had the same reason behind their despair. They were nothing more than lab rats.

"Can a human mate and produce an offspring with shuuki? What a ridiculous notion. Though watching those humans struggle so much for an answer is amusing to see, so sneaking in here might be worth while."

As Shikoku said this, she noticed how there was one girl sitting inside the corner of her cell. The girl had black hair in a thick braid tied with a light-colored ribbon down her back and a loose fringe over her forehead. Her eyes were a shade of dark blue similar to her younger brother. Her dark red kimono and hakama torn as if something ripped them.

"........"

"Excuse me, did I do something wrong again?"

"What is your name, human?"

"Tomioka, Tomioka Tsutako."

"I see, well then. Depending on how you answer, you may live after today or not. Tell me, what is your story?"

~Meanwhile~
Outside of the facility where Tsutako and the girls were being held, numerous amount of boys were seen breaking rocks or picking up leftover body parts of shuuki nearby. The people captured here are victims that were suddenly transported into Mato. While the girls were held inside of the facility to be tested, the boys were tasked with dangerous chores since they had no powers and would be useless to the experiment otherwise.

"The results of the brides are in. Nearly most of them either lost the will to live, became a vegetable, or killed themselves just because they couldn't handle the task. Worthless! Most of these brides are worthless, just like the human debris out here!"

A woman was seen angry with the results as she threw her clipboard at a nearby boy's head. She was a woman with an average build as she had a black dotted snake tattoo going down both her arms. Her facial features consists of eyes containing yellow irises with black pupils, and blonde hair arranged in a spiked style, with two long strands extending downwards framing either side of her face, that entwine each other like a caduceus' snake to rest upon her chest.

"Well I guess there's a few human debris and a couple of brides who are of use."

[Former Onmyou Agency Member:Medusa Gorgon]

As Medusa looked around, she saw a boy who was bleeding from the top of his head. His hair was pitch black as his blue eyes held no type of light in them. His clothes were nothing but rags. The boy simply walked back to Medusa and handed her the clipboard as he simply went back to work.

[Human Debris:Tomioka Nagisa, 6 years old]

"Boy, did you finish your tasks?"

"Yes."

After saying this, Nagisa took a sack out of his pocket as he handed it to Medusa. The moment she opened it, Medusa's eyes widen in shock. Claws, tails, eyes, pieces of skulls. Right in Medusa's hands were various parts of already killed Shuuki.

"Debris, do you know what this will be used for?"

"........"

"Shuuki are animals. Normally a wild animal is difficult to train, but I noticed something. When fed their own kind or stimulating their primal instincts with the scent of another shuuki after starving them, it's easier to send subliminal messages to order them."

"Will my sister continue to be okay?"

Medusa was shocked by the boy's neutral expression. The boy did not even care that his actions was actually helping her experiments, all he wanted to do was help his sister. Soon a smile slowly formed on Medusa's face as she looked at the young boy.

"Young debris, if you can keep gathering materials like this and we accelerate our project, you and your sister can go the moment it is complete. All you have to do is follow my orders. Understand Mister......."

"My name.....what was it again...........the only title I remember having is Human Debris."

"Good answer."

~With Tsutako~
"Can a human with a peach ability breed with a shuuki and produce a child. That one theory is what started all this. The lead researcher, Medusa, wanted to explore this theory with the others amongst the Onmyou Agency. However, they rejected that very notion, saying if such an offspring were to occur, it would be disastrous."

As Tsutako said this, she soon pointed to the cell across from her. When Shikoku turned her gaze in that direction, she couldn't believe what she saw. One girl was foaming in the mouth as her face held a look of absolute terror. Another girl was hugging her own legs as she was in the corner with scratches and bruises on her body.

"See those girls, just today they were forced to become mates, or as the researcher calls them, brides for countless shuuki. The Shuuki would mate with the girls here after being exposed to a stimulus and they chose peach users as the subjects since they could handle more than an ordinary human."

"What about you? Were you forced to do this too?"

"Of course I was. This body was defiled more times than I could count. Everyday I wanted nothing more than to die, but I have reason to keep going. My precious little brother still has his life ahead of him. To endure this pain so my little sibling can keep moving forward, that's the job of an older sister, isn't it?"

~Outside~
"Pathetic."

After her chat with Tsutako, Shikoku had left from the facility with a sinister smile on her face. At first she came to destroy the base and kill everyone there due to how they captured the shuuki under her control, but this turned out to be a more interesting find.

"So pathetic! She had her body toyed with and she endured it all because of a little kid. Pathetic, humans really are pathetic!!!!"

Shikoku couldn't help but laugh at this situation, however, things were going a little too slow for her taste. Just as she thought this, Shikoku suddenly dodged several arrows that were aimed to stab her, when she turned around, she saw Medusa standing before her.

"Just who the hell are you? How did you find this facility, you brat?"

Just as Medusa said this, she suddenly found herself pinned to the ground as Shikoku had a tight hold of her face. When Medusa looked at the creature, she saw Shikoku with a sadistic smile on her face. Right now, Shikoku was starting to show more and more interest in this little project.

"I'd watch your tone if I were you, human. After all, I have something that might help accelerate your research."

"......just what the hell do you want?"

"Simple, I have a specific shuuki under my control. One so powerful even the Anti-Demon Corps wouldn't be able to handle it without casualties. I'd be willing to bring him here and have you give him a bride. In exchange, I want to see it .......the face of a woman in utter despair as her life ends in front of the person she holds most dear!"
