Fuyumi: Greetings. I'm Fuyumi and this is my very first fanfiction ever. Starring my wonderful OC, Yukiyo Sanada. Now then, I'm too lazy to do the disclaimer myself so I'll have one of my minions do it. Hmm . . . YUSUKE!

Yusuke: What do you want, Fuyu? Can't you see I'm busy?

Fuyumi: Yusuke, read the disclaimer for all the nice people.

Yusuke: Do it yourself.

Fuyumi: Do it or else I'll tell Keiko about the time–

Yusuke: Fuyumi Togashi does not own Yu Yu Hakusho or any of the characters. She does claim ownership over Yukiyo Sanada, Ryusuke Sanada, and Mayumi Takeda, even though that last one's not too important. There, happy?

Fuyumi: Thank you, Yusuke!

Yusuke: Yeah, yeah, whatever

Sayonara wa Iwanai: Never Say Goodbye
Chapter 01: Introductions

What had been a blissful snowy day was drawing to a close. The fluffy white precipitation was drifting slowly down to the earth. A young woman was seated in a rocking chair, dark purple orbs staring blankly out the window. Her eyes were adorned by black circles from lack of sleep. She was fairly young, still a teenager, but she looked rather aged from fatigue. The reason for her tired appearance was seated on her lap.

A small boy was tracing his finger down the frosted window pane, a thin line trailing after his finger. He smiled delightedly as he made the line longer and longer. This bouncing baby boy was the reason the woman could not sleep. She had to wake up very early due to the crying and wailing of her year-old son. She wished for those lost days when she could get at least eight hours of sleep but decided the lack of sleep was worth having this beautiful boy.

The boy's name was Ryusuke Sanada, christened with his mother's last name. His mother, Yukiyo Sanada, was not married so the boy assumed her last name. As for the father, he disappeared almost instantly after Yukiyo revealed to him she was carrying his child. In truth, Yukiyo herself almost ran away from this pregnancy.

Not many fourteen-year-old girls would go through with having their baby. She could've settled for an abortion or even adoption but Yukiyo couldn't. Even though her baby's father disappeared after she told him of her pregnancy, Yukiyo wanted to keep this baby. She hid it well from everyone, still attending school as if nothing was wrong. To her misfortune, her mother found out that she was pregnant when she found one of Yukiyo's private emails from her doctor. How her mother got into her account still puzzled Yukiyo.

After reading the email, Yukiyo's mother went into a fit of rage. She came home and her mother immediately slapped her across the face. The words that her mother said strung harder than the impact of her hand striking Yukiyo's cheek. She yelled such terrible things. Yukiyo and her mother were fairly close, always laughing and joking, but now they were warring against each other. The things her mother said to her still hurt as much as ever.

It had been almost about five months since Yukiyo's mother kicked her out of the house. Having nowhere to go, Yukiyo turned to a homeless shelter and when she told them she was pregnant they said that they could help her take care of the baby for no charge. Yukiyo had become relatively close to one of the employees by the name of Mayumi Takeda.

Mayumi was fairly young at the age of twenty-four and she had become a somewhat older sister for Yukiyo. Mayumi even helped assist Yukiyo in the birth of her son. Yukiyo had gone into labor much sooner than expected and Mayumi, who attended medical school, helped the baby along and welcomed Ryusuke into the world.

Since Yukiyo was a teen mother with a baby son, she was given her own small room to share with her son, rather than a large room with several cots. She slept on a futon while her baby resided in a slightly wobbly cradle.

Ryusuke peered up at his mother, blinking his honey-colored eyes. "Ah-Ma," he said with a big smile. Yukiyo smiled. Just being called "Ah-Ma" could bring a smile to her lips. Ryusuke had yet to say "Mama" but "Ah-Ma" was close enough in Yukiyo's opinion. Ryusuke drew another long line down the frosty window pane then clapped merrily. The simplistic joys of a child were a beautiful thing. The door to the Sanada bedroom opened.

Walking past the doorframe with none other than Mayumi, her black hair in a long, flawless braid going down her back. Ryusuke looked to Mayumi and smiled, reaching out with his little hands as if he were grabbing at the air. "May-May, May-May!" While "Ah-Ma" was Yukiyo, "May-May" was the name Ryusuke had christened her with. Mayumi walked over and planted a kiss on the infant's temples. She looked up at Yukiyo.

"How are you?" she asked kindly.

"Well enough. And you, Mayumi?" answered Yukiyo.

"I'm fine." Mayumi smiled. "And how is Ryusuke?"

"Well, at least he's grown out of his hair-pulling phase." Yukiyo ran a hand through her dark brown locks. "I thought I was going to have to buy a wig the way he kept yanking out my hair."

"Heh, well he's inherited your hair color," remarked Mayumi, noticing the dark brown tuft of hair that spurted from the young boy's scalp. She took Ryusuke into her arms who made noise between a squeal and a gleeful laugh. She gently rocked him as if he were her own child. "Yukiyo, I came to tell you there's a man here to see you."

Yukiyo's face paled. "If it's Nimashi tell him to go tell hell!" snarled Yukiyo viciously. Mayumi shook her head, still rocking Ryusuke in her arms.

"He says his name is Koenma," said Mayumi gently. "Friend of yours?"

Yukiyo's face paled. She'd heard that name once before. Koenma was her sister's former boss. Her sister's maiden name was Kuroko Sanada, and she had once had an occupation that went by the title of Spirit Detective. Kuroko was no longer working in that profession, married a novelist by the name of Shogo, and now lived her life as Kuroko Satou, a married woman with two children. Her son's name was Kaisei and her daughter's name was Fubuki.

Kuroko told Yukiyo the strangest things. She said that there were three worlds: Human World, also known as planet Earth, Demon World, and Spirit World. Koenma was the son of the great King Enma, ruler of the Spirit World. Kuroko was only fourteen when she was recruited to be Earth's Spirit Detective.

Spirit Detective was a strange and unusual profession. When Kuroko visited home, she would tell Yukiyo tales of fighting ghosts and demons. Yukiyo didn't believe her. She was much more sensible than that. Still, that did explain quite a few things.

Yukiyo always had a bit of a sixth sense. Sometimes she would see very pale-looking people but then they would vanish right before her eyes. She often got chills up her spine and could tell when she was being followed. Kuroko was also gifted with this supernatural ability. According to Yukiyo's sister, this was not merely psychic power but more along the lines of Spirit Awareness.

Spirit Awareness is how in touch regular humans are with the supernatural forces around them. Kuroko had an exceptionally high Awareness and that is one of the main reasons she was chosen to be the crusading Spirit Detective for the Human World. Yukiyo also learned from Kuroko's stories about spirit energy. Every living being had spirit energy within them but only gifted humans could harness and control it. Kuroko was able to do this under vigorous training by a woman named Genkai, a very well-known spiritualist with phenomenal power. Genkai was also a human acquaintance of Koenma.

Yukiyo never before believed her sister's stories. In fact, Yukiyo thought her sister needed to see a therapist. But now a man named Koenma was here to see her. Could it be the same Koenma that Kuroko had once worked for? Maybe it was just a coincidence.

"Uh, Yukiyo?" said Mayumi, her voice dragging the teenage girl back into reality. "Do you wish for me to send him up or not?"

Yukiyo nodded slowly. "Yes . . . tell him I'm ready to see him," she said in a low tone of voice. Mayumi frowned a bit but nodded, returning Ryusuke to his mother. Ryusuke gave his mother a toothless smile as he gripped at the front of her shirt. Yukiyo held her precious treasure against her body, gently bouncing him on her knee. She kissed his forehead swiftly.

Yukiyo's pulse quickened at the sound of approaching footsteps. She received a visitor at the door to her bedroom. It was a young man wearing khaki slacks and a long red cape. The middle of his brow had the word "Jr" displayed on it. He looked at Yukiyo with amber eyes. He bowed humbly.

"Greetings, Ms. Sanada," he said properly. "My name is Koenma. Perhaps you've heard of me from Kuroko?"

So it was true. This really was Kuroko's former employer. But what would the prince of the Spirit World want with Yukiyo. Sure, she was Kuroko's sister but Kuroko had cut off all ties with Spirit World so there was no reason for Koenma to be visiting her. Ryusuke giggled as his mother held him a bit tighter. "What do you want with me?" Yukiyo said rather brashly. "My sister's done working for you so I hope that's not what this is about."

Koenma shook his head. "No, no. This matter is entirely different." He shut the door and locked it. Yukiyo arched an eyebrow and the prince replied, "We are discussing matters of the Spirit World and as such others shouldn't pick up on what we're discussing."

"Would you be so kind as to tell me why you're here?"

He glanced at Ryusuke. "This ordeal regards the boy resting in your arms."

Yukiyo's breath hitched but she kept a calm face. "What do you want with my son?" She held him protectively as any good mother should do. Ryusuke, not having the slightest idea what was happening, innocently blew spit bubbles and laughed in a shrill voice.

"Tell me, Ms. Sanada, is it true that the father of your son is a Mr. Nimashi Kadohata?"

Yukiyo's blood went cold. Her entire body numbed. For a split second time had stopped. That name. That one name was enough to make her body become like a statue. The air in the room had become stifling.

"Ms. Sanada?"

She could hear Koenma well enough but Yukiyo's body was on a temporary shut-down. That name. That . . . that name made her heart ache. That name made her want to break down and cry. It made her want to throw something. It made her feel afraid. The name itself had control over her and her emotions. That name . . . his name . . . made her go into a catatonic state. This one didn't last long, for she snapped out of it when Ryusuke squalled, "Ah-Ma."

Yukiyo shook her head and blinked her eyes a few times. Inhaling shallowly, she focused back on Koenma. She answered his question regarding the father of her child with a nod. Koenma did not look surprised.

"I see . . ." he said vaguely. "Well, that confirms Spirit World Intelligence's theory. " He sighed, briefly running a hand through his brown hair. "I was hoping that it wouldn't be true."

"Excuse me, but what's true?" Yukiyo had decided to be a little more polite to Koenma. After all, he can't have been too bad of a guy if Kuroko worked for him. Kuroko was an honest and noble woman who fought for mankind. Surely if Kuroko could tolerate being under his order than Yukiyo could show him a little respect. He was King Enma's son, after all, making him the prince of Spirit World.

Koenma pursed his lips together. "This may be difficult for you to swallow but your son, Ryusuke . . . is a half-demon."

"Y-You're lying," said Yukiyo automatically. She wouldn't believe it. She couldn't believe what she had heard. Her son was not a half-demon. Demons were ugly and evil creatures. Her son was adorable and innocent. He was a pure human. Besides, there was no way in hell Nimashi could've been a demon. Kuroko had taught her basic skills to control her Awareness and among what she had learned, Yukiyo discovered how to tell if someone was human or demon. Nimashi had no trace of a demonic aura so how was this possible?

"Ma'am, I wouldn't lie about something as serious as this," Koenma said earnestly. "We are positive your son is a half-demon."

"But Nimashi is human and so am I! How is that possible?" It made no sense. To produce a half-demon offspring one parent would half to be a full demon, and neither Yukiyo nor Nimashi were of the demon race. Koenma, however, seemed to think differently.

"Ms. Sanada, there is information about Nimashi Kadohata you need to know. First and foremost, his name is not Nimashi Kadohata at all. His true name is Shinzo. And now to throw you for a loop, Shinzo is a demon."

Yukiyo shook her head, dark brown tendrils whipping her jaw. "That's impossible! I would've sensed if Nimashi were a demon! Kuroko taught me how to sense them!"

Koenma sighed. "Yes, but you see, your sister did not give you a full lesson. Shinzo is a demon of many talents. He's from the rare bat demon tribe and he can mask his energy almost perfectly." Koenma paused as Ryusuke let out a horrible crying sound. Yukiyo apologized, soothing the wailing infant. Ryusuke's shrill cries stopped and Koenma continued on. "You are a novice when it comes to your Awareness so if he masked his energy you wouldn't be able to tell. That explains why you sensed him as a normal human."

"There's still something I don't understand," murmured Yukiyo. Her head was throbbing with this new information. It couldn't be true. Things were already bad enough with her living at the homeless shelter but now it is certain that Ryusuke is a half-demon. "If Ryusuke is really a half-demon like you say, then how come I don't sense any demon energy from him? I mean, he's a baby! He surely can't mask his energy."

"Your son is a different matter," said Koenma eloquently. "Your son won't have a demonic aura until he is of a certain age. Until then, it will seem like he's just a normal human. But soon his powers will develop and he will noticeably become a half-demon."

Yukiyo gripped onto her son, who was reaching for the frosted window pane. The crooked lines he had drawn on the pane were still there. Her eyes were watering and she sniffled. " . . . What do you want with Ryusuke?"

"We need to take him to Spirit World for an exam."

"What kind of exam?" Yukiyo felt her motherly instinct to become protective of her child shoot up. "What do you want from him?"

"Rest assured, your son will be fine. We just need to draw a sample of his blood."

Yukiyo's grip on Ryusuke was so firm she saw him wince as he released a sharp yelping noise. "Why do you need that?" she demanded icily.

"Because," said Koenma, unfazed by Yukiyo's cold glare, "we need to see how soon it will be until the demon DNA within your son will awaken. You see, your son is of great importance to Shinzo."

Yukiyo snorted. "That is the biggest load of crap I've heard in my life! He ran out on me when I told him I was pregnant."

"But Ryusuke is far more important to him then you seem to realize."

"How so? Explain it to me."

Koenma sighed heavily. "Tell you what. I'm taking you to Spirit World. Bring Ryusuke with you–we have to get that blood sample. And while we're there I'll explain what's going on more throughly."

Yukiyo's body was trembling. She was holding her baby so tight that if she applied anymore pressure she might injure him. Reluctantly, she rose from the rocking chair, cradling her small son in her arms. He squealed delightedly. Yukiyo looked down at Ryusuke and she wanted to cry. Her baby boy a half-demon . . . and what did Nimashi, or rather Shinzo, want with him? Well, whatever his reasons, he couldn't have Ryusuke. Yukiyo would never let her son fall into the hands of that bastard.
