"Seems like she's finally calmed down." Azazel finally spoke after several minutes of silence between the five of them.

At the moment, Yukiyo and his team were standing in the Governor-General's office, staring at a monitor that depicted the prison cell that Kuroka had found herself in upon regaining consciousness. It was a large concrete cell with an area around twenty feet by twenty feet with no carpeting and a single bed and toilet, there were no windows and the door was steel and barred. Not only that, but the cells walls and door were etched with wards and rune sequences that created high level imprisonment bounded fields that robbed the prana of anything that struck them with the intent to escape. The first thing the Stray Devil did upon regaining awareness was to go on a rampage and attempt to break out of the concrete cell that they had placed her into, with no success of course. It only took several minutes before the Mana within her system that was driving her insane was siphoned from her body when she repeatedly hit and clawed at the walls and doors until she lost consciousness a second time. Several hours passed in silence until she woke up again and moved to sit in the middle of the cold floor.

None of them formed a response until Azazel waved his hand and a portion of the wall that hid the monitor moved and slid back into place. "I want to congratulate all of you on your resounding success, it's not everyday that Grigori captures Senjutsu users."

Vali shrugged, "It's not like she was any strong, her moves were easy to read and she didn't really make any effort to hide from me once I went to look for her."

Yukiyo rolled his eyes, "It's not like we had a Longinus, a Holy Sword and a Reality Marble on our side to help calm her down or anything." He said easily. Everyone in this room knew that he had a Reality Marble, and it wasn't like he was keeping anything hidden from them.

Azazel had found out after he gave the teen a checkup once Yukiyo officially agreed to join Grigori. The doctor conducting it had been hypnotized and forced to forget to maintain anonymity. Satellizer found out because he told her about it, he couldn't keep much hidden from her for long. Vali and Arthur had found out once he'd sparred against them. Vali had demanded time and time again that he go all out when fighting him, but he refused. Unlimited Blade Works, while powerful, was nothing compared to a Juggernaut Drive enhanced White Dragon Emperor who was the descendant of the original Sin of Pride.

Vali scowled and looked to the side while Azazel smirked at his comment, "Was she so much trouble that she made you use it, Yukiyo?"

The teen in question shook his head, "She was under the effects from Gaia's hatred, if she was sane she would've given us a lot more trouble."

The head of Grigori nodded before turning to the rest of them, "Why don't you all take some time to relax for a while, I'll call you guys up if I need you." The four nodded before they turned and began to leave, "Hold on a second Yukiyo, I want to talk to you alone."

They stopped before Vali shrugged and walked out of the room, Arthur bowed before following after a few minutes. Only Satellizer lingered after the other two left. Yukiyo gave her a smile and grabbed her hand and planted a small kiss on her head.

"I'll be fine, you go relax."

Satellizer scowled for a second before she sighed and walked out of the room, the boy sighed, knowing that he'd have to make it up to her later. He pushed those thoughts out of his mind and closed the door before turning to Azazel. His face turned back into the steel mask that had become it's default expression.

"What do you want?"

The Fallen smirked, "My my, so rude to the man who took you in, I thought you'd be a bit more grateful for the graciousness of a black-hearted Fallen Angel such as myself."

Despite himself, Yukiyo gave a small snort. "Graciousness my ass, you took me in because you thought I was interesting."

Azazel closed his eyes but didn't refute the statement, all the while maintaining his smirk. That soon faded however as his face turned unexpectedly serious. "Yukiyo, the reason why I needed to speak with you, is because you're one of the few people that I can trust with this information."

The incarnation raised an eyebrow at that as a motion to continue, "I have gained some evidence that there's been a splinter group that've turned traitor to Grigori and working in a different organization."

Yukiyo's brows turned into a scowl as he realized what Azazel meant. "Do you have a name for the organization?" He asked, in response his foster father shook his head in the negative.

"At the moment, I've got nothing other than superstition and my own paranoia. But I believe that our new prisoner can assist us with drawing out an agent from the group that snatched away our soldiers."

The corners of Yukiyo's mouth fell into a frown, "So you plan to use the potential of a Senjutsu user to lure them out?"

Azazel nodded, "Senjutsu users are rare enough, but to find a Nekoshou, well, that's even rarer."

Yukiyo had to fight back the urge to widen his eyes, how did the old man figure it out that she wasn't just a Nekomata that easily? Was it her aptitude for the spiritual arts? Or maybe the fact that Nekomata were just so rare. The teen soon brushed it off and moved his thoughts forward.

"So what do you need me to do?"

At this, Yukiyo felt a very slight amount of dread at the smirk that suddenly sprouted across Azazel's face.

"I want you to train her."

At this point, Yukiyo stared at Azazel as if he were senile, "You can't be serious." The man's remaining smirk answered his inquiry. "I'm not a teacher, and even if I was, I'm not a sage."

"She doesn't need help when it comes to controlling mana, she just needs to learn to manage her temper." The man spoke with a small hint of amusement in his tone. "Something you can do wonderfully."

Yukiyo scowled, "What does training her have to do with luring out traitors anyway?"

Azazel's face turned serious. "Yukiyo, these aren't just small time traitorous exorcists or the lower-class Fallen Angels. I'm talking about potential high-class Fallen, maybe even a few Cadre."

At that, Yukiyo's brow raised in slight amounts of shock. He knew that there was one cadre in particular that would turncoat. But that was several years down the line. Did Azazel suspect the lord of the stars this early on? Or was it mainly due to his presence and the presence of Kuroka that the old man grew apprehensive against him.

"So, do you accept?"

Yukiyo quickly wiped the shock from his face, his eyes turning to small jades. "When do I start?"

Azazel smirked and he leaned back in his seat, "You'll start tomorrow, as you'll no doubt be preoccupied trying to appease a half-daemon tonight." At that, Yukiyo allowed a small sigh before closing his eyes and nodding, which only prompted the damn grin on Azazel's face to increase, "I recommend applying reinforcement beforehand, wouldn't want you to break a few ribs, or keep you from giving me gran-"

Azazel's sentence was cut off when he found that he now had a bump on his head from a shinai kendo sword with a small tiger charm on its pommel.

The sword incarnation growled as he moved through the hallways of Grigori HQ, his strides were long and fast, and his muscles were tense from irritation. His face was set in a dangerous scowl as he walked down the fluorescent corridors. After Azazel had fallen over from the blow to his head, the teen promptly excused himself from the circular office that belonged to his foster father. He'd been wandering for several minutes now, trying to discover a way to expel the fire that was coursing through his blood. He was abruptly jolted from his thoughts when a small cry made him turn in small amounts of surprise.

"Onii-sama!"

When he completed his turn it was to a young girl with bright silver hair sprinting towards him. She was wearing a white jacket with a red collar and a black skirt with a grey belt tied around her waist, thigh high stockings and white sneakers completed the look. Strapped to her side was a sheathed shorter variation of a Japanese Katana. Her gentle face was turned upwards in a bright grin and her eyes were glinting with barely repressed joy.

Despite his foul mood, Yukiyo found his mouth twisting into a wry smile as the girl promptly tripped over her own feet and her face planted into the floor. She quickly got into a kneeling position before her face began swimming with tears. Yukiyo quickly made his way forward before taking off his scarf and wiping the girl's eyes.

"You should be more careful, Kirin, it's not like I was gone for long after all."

The girl sitting in front of him pouted, "Mou… I came running because I heard from Nee-san that Onii-sama got in trouble with Azazel-tousama."

Yukiyo's smile flickered for an instant. "I didn't get in trouble, the old man just wanted to talk with me about a few things after the mission."

Kirin's pout was replaced with a bright smile as her eyes sparkled with relief. Her grin happened to be infectious as he found his face easing into an easy smile. Yukiyo found Kirin while on an assignment in Japan a couple months ago. She was the girl that he happened to save years ago, back when he claimed his first kill. When she found him, she refused to let him go and latched on to him all the way back to Grigori. Vali laughed for several minutes when he found out how his fellow silverette had come to HQ. Azazel had adopted the younger girl as she had no family that none of them were willing to let her go back to.

"Onii-sama?"

Yukiyo was brought from his thoughts by an inquisitive Kirin, her grin was gone, instead replaced with innocent curiosity and slight amounts of worry.

"You have a scary look on your face."

Yukiyo blinked before he stood up and offered her a hand. His lips tugging into reassurance. "I'm okay, why you show me how much you've improved with that sword on your belt." When he finished speaking Kirin's eyes brightened and she nodded before eagerly taking his hand and leaping to her feet before dragging him in the direction of the sparring grounds.

-XXXX-

Yukiyo was now wondering if he'd made a mistake.

At the moment he was standing in the Grigori's sparring grounds, an artificial forest-like area with bright fluorescent lights above him. Standing across from him in the false grass was Kirin, her face scrunched into a sharp scowl that would've appeared adorable under different circumstances. He was holding his favoured pair of married blades and she held her drawn katana, the edge pointing directly towards him. It seemed like an instant before Kirin's form vanished and reappeared directly in front of him before lashing out at one of the openings in his stance.

He quickly raised Kanshou in opposition to hers before lashing out with Bakuya. Forcing her to disengage before moving her sword along in a flowing and graceful series of spins, her entire body blurring as her sword followed. Yukiyo grit his teeth as they traded blows, small cuts opening on both of their bodies.

This was Kirin's true abilities, he gave her his family name, Himura, when she was officially adopted as his younger sister. With Azazel being their legal guardian. But before that, her surname was Nanaya, one of the four great families that made up the infamous Demon Hunter Organization. Humans that bred monsters to fight other monsters. They were later purged by the Devils and Grigori, along with the families of the cardinal beasts, due to unprovoked attacks on foreign factions. The few that were left went into hiding and continued to hone and pass on their skills. Kirin was trained from birth ever since she could manage to crawl. In fact, she was a completely emotionless killing machine until she met the woman who would effectively become her mother figure.

That woman taught her about emotion, about joy and anger. Eventually Kirin ran from the Nanaya hideout where she was later held hostage by a serial killer and saved by a boy with black and white hair.

Yukiyo was taken from his train of thoughts when Kirin's eyes flashed a bright blue color and she slashed diagonally along Kanshou. The sword then breaking in half as if it were butter. Yukiyo's own eyes narrowed and he blocked with Bakuya before tracing another Kanshou. This was another reason why Azazel had brought Kirin into Grigori besides her powerful Nanaya assassination arts,

Her Mystic Eyes, specifically the considered nonexistent Mystic Eyes of Death Perception.

Yukiyo knew that each member of the Nanaya clan had consistently acquired Pure Eyes, but for those to mutate into something else. Well it was rare beyond all belief. It was due to both of these traits that Kirin was considered a force to be reckoned with. She'd already been on several missions, all of which involved him.

His thoughts returned to him and the two resumed their spar, however to an untrained eye it would look more accurately be called a dance. Ambient prana flowing off of Yukiyo's palms from the continuous projection he was undergoing. If they were to continue at the pace they were going, either he would lose, or it would be a draw. His eyes narrowed as he attempted to come up with strategies to counter Kirin's various attacks but nothing would come through as she could just "kill" anything that he would Trace. Abruptly, his strategizing ceased when Kirin jumped away, her sword poised in front of her and her eyes narrowed. After several moments, her mouth opened.

"What is it that's distracting you, Onii-sama?"

Yukiyo quirked an eyebrow at her question before he closed his eyes and sighed while simultaneously letting his swords dissipate, "Let's take a break."

Kirin nodded and sheathed her blade, slowly she walked over to him as he sat cross legged on the pristine floor of the training grounds and matched his position. Her eyes drifted toward the ground as she thought of the spar, it was true that she could beat Yukiyo in the real world, but if he were to use the full unrestrained might of his magical capabilities, then she truthfully didn't know who would win. But today was different, he was invested in the battle as always, but it wasn't like he usually was; there was a part of him that was off somewhere else, as if he was here, yet there was something hanging over his head.

"Onii-sama," Yukiyo looked over to the girl upon being addressed, "Did you and Nee-san have a fight?"

Yukiyo glanced at Kirin before shaking his head, "Satella is a little frustrated with me right now, but that's not what's been distracting me." He paused for a moment before continuing, "What do you know about Senjutsu Kirin?"

She looked at him in a small amount of surprise before looking down in an attempt to try and remember what she was taught on the subject both by Azazel and the Nanaya household. "Well, Senjutsu is the ability to use the natural energy of the planet itself and to combine it with the energy produced by your own soul to manipulate the surrounding area." She looked up for a moment to see Yukiyo nodding at her with a small amount of encouragement, "Senjutsu practitioners, or Sages, if they have enough experience in the arts can even learn to manipulate the planet's natural forces, such as time or gravity."

"But this comes with the risk of?" Yukiyo interrupted.

"Taking the malice of the planet within yourself." She answered easily, "The planet has been around for a long time, and as long as humans have existed, they've been exploiting the resources provided by the world and as such, this has caused the planet to amass a large amount of Malice towards humans and living beings outside of monsters or nature spirits."

Yukiyo nodded and Kirin looked back to him, "But how has Senjutsu been distracting you, Onii-sama? Have you decided to try and become a sage?"

He looked to the ground at that before sighing, "Earlier, Azazel had sent me and a small group to secure a stray devil." Kirin raised an eyebrow as he continued to explain, "She was a Sage, a powerful one at that, the only issue was that she had lost control from the planet's hatred and as such, had gone berserk." Kirin's eyes widened and he paused for a moment, a Sage who had lost control was certainly something to be feared if they had enough experience with their craft. It was comparable to a Berserker class Lancelot that could travel through time and bend space to his whim, thankfully, experienced Sages had an easy enough time brushing off the planet's malevolence and keeping a level head, which was vital in both Magic and Senjutsu.

"Is the Sage the reason why you're distracted, Onii-sama?"

Yukiyo shook his head in response, "I'm more 'distracted' because Azazel asked me to train the Sage in how to properly control her powers."

Kirin raised an eyebrow at that, "Why? Onii-sama isn't a Sage, and you don't have any experience in controlling the arts."

Yukiyo shrugged, "He said it was because that I have experience in 'controlling my temper' but I don't have a lot of experience with that either."

Which was the truth, no matter that Yukiyo tried to act level headed. There was always a fire simmering beneath the surface of his icy mask of rationality. It had been there ever since he'd seen his mother's corpse, a hatred of everything that lived or breathed, including himself.

"You mean the rage at your mother's death." Kirin pointed out, she was one of the few that knew of his reason for training so hard to contend with those of the supernatural. At his core, he was an embodiment of rage and hatred, and all of that was sitting behind his human flesh, a monster made of swords that was waiting to be unleashed. "Onii-sama, maybe you should think about it from your mother's view," Yukiyo's fists clenched at that and he bit his tongue to keep from lashing out at Kirin "Would she ever want you to lose yourself to rage?"

"Hate is a double-edged sword."

The teen's eyes widened as he remembered the promise that he'd made with an old Fallen Angel all those years ago.

He smiled and ruffled Kirin's hair, causing her to let out a small "ummm" of surprise and slight pleasure. His smile grew to a smirk as he stood up and turned, moving outside the white walled training room and towards his own room.

"Onii-sama?" He paused at hearing Kirin's unasked question and turned back to her,

"Thanks, Kirin, you reminded me."

Kirin blinked once out of confusion before he turned around and continued walking down the hallway. He would worry about Kuroka later, but for now, he would find Satellizer and comfort her in one of the few ways he knew he could.

By making her feel like the only woman in his life.

When Yukiyo arrived back at his room, Satellizer was standing in front of their mirror brushing her hair. When he entered she set the brush down and turned to him, her face set into its standard scowl as she walked up to him and furiously smashed her lips against his. She shoved her tongue and twirled into it and he responded with equal fervor. Satellizer growled as she tore off his upper body armor and began to lead him towards their bed.

AN: Yeah, I probably could've brought in what I have planned, but I want to save that for next chapter. Have to say I'm not exactly proud with how this turned out, but I at least wanted to give you guys something before I drop off the map again. I won't give a set date, it feels way too restricting to have a concrete schedule and I would like to work at my own pace. Now to address the elephant in the room, I'm putting Dragon Death God on an indefinite hiatus, I'm not proud of that story and the plans that I have would take too long to put out, and I don't want that story to take up mys conscience.

Please leave a Review and tell me what you thought about this chapter, like what you liked and what you think I could improve on. If you like this story than be sure to follow it so that you know when new chapters are going to be released. And if you like it quite a lot then please favorite it, it would mean a lot to know that my readers actually like the story.
