Yo. Hi there! I'm Hisa. This is the first time I've ever posted on of my fics, so please, constructive criticism only. If you do flame me I'll be forced to exact my revenge on you by having my army of cats use you as a litter box. Oh, and I would love it if you would send me some suggestions for a name later on too.

Hiei watched intently from the windowsill as Kurama sat on his bed looking through the research material he had collected earlier in the day for his English report. Papers and books were scattered across the cool blue bed sheets, surrounding the redhead. Hiei found it slightly amusing that the greatest thief in the history of the Makai willingly took hours out of his day to please a mere nengin woman. He also found that his fox-turned-ningen looked more than beautiful with such a concentrated look upon his face. His green eyes shown brightly in interest at the paper he was presently enthralled with; his fiery red hair was mostly pulled back so that it would stay out of his face while he worked, but a few stubborn strands still attacked his face and a large escapee cascaded down over his shoulder. A small smirk played across Hiei's face. He could not have wished for a better mate.
"Hiei, why are you watching me?" Kurama asked without removing his emerald eyes from the paper in his hand.
"Because I'm your mate and I'm allowed to," Hiei replied with no hesitation.
Kurama smiled at Hiei's response. It had taken Hiei nearly a year to get warmed up to the idea of even having a "mate" as he called it, but now, after nearly three and a half years together, Hiei didn't mind showing affection to Kurama as long as the others did not see it. Kurama had nearly keeled over from joy when Hiei had returned from one of Mukoro's missions and Hiei had willingly admitted how much he had missed his fox. Which was promptly followed up by a night full of enough fun to more than make up for Hiei's month and a half absence.
That had been two days ago, and Hiei didn't seem to want to take his eyes off of the kitsune, and Kurama was more than contented to have Hiei with him most of the day.
"Kurama?"
"Hm?"
"What is your report on?"
"I have to find a book that interests me and write a report on it and the author."
Hiei hopped down off of the windowsill, moved to the bed, and sat down next to Kurama, a slight scowl present on his features.
"Sounds time consuming," He remarked, his eyes scanning the papers they were surrounded by.
Kurama faced Hiei and smiled.
"Don't worry koishii, I won't be to busy to spend time with you,"
"Hn.."
Kurama's smile fell as he observed the disappointed frown gracing Hiei's face.
"I know," he said, his smile returning. "How about I prove it to you. We can go out tonight, how's that?"
Hiei's smirk returned to his face as he cast a sideways glance at Kurama.
"I suppose that would suffice,"
Normally, Hiei would never want to go anywhere "baka ningens" happened to be, but it seemed to make Kurama happy, and if Kurama was happy, so was he. Hiei loved the way Kurama's eyes would light up with joy every time he saw a new, exotic flower, or tasted a new tasty food. This was a night Hiei could look forward to.

"Well, I bet you're wondering why I called you here," Said Koenma, still in toddler form.
Hiei stood in the corner, looking even more agitated than usual. He and Kurama were meant to have a date at about this time, but it seemed that the pacifier-sucking ruler always knew the exact worse time to call the tantei into action. Kurama, for once, looked equally as annoyed as Hiei. It wasn't everyday he had the opportunity to show off his fire demon.
Yusuke was just as aggravated at Koenma as usual, while Kuwabara seemed abnormally hyped about having a new mission. Apparently he saw it as another chance to prove his love and manliness to Yukina.
"You have a new and extremely dangerous mission," continued Koenma. "Another demon has escaped from the Reikai prison. I know what you're thinking; you think this will be the same as every other yokai escapee. Well, you are gravely mistaken. This yokai is above S class. He's stronger than Mukoro. By far. That's why I'm also calling upon the Makai rulers to assist you in the operation."
Needless to say, the four tantei were shocked into an uncharacteristic silence. Kurama had unconsciously moved closer to Hiei, while Yusuke and Kuwabara had dawned their rare serious faces.
Koenma scanned the room's faces and took their silence as a queue to continue. He picked up the small remote sitting on the edge of his desk and brought the screen beside him to life. On the screen appeared a demon that looked remarkably like Hiei, with the exception of height and coloring. He looked to be around six feet tall and he was rather lanky. The back of his hair was longer than Hiei's and was pulled into a braid that fell over his shoulder, and although the hair on top of his head stood up the same as Hiei's, it was all white with a black star and red tips. His eyes, instead of red, were an icy aqua, more green than blue.
Koenma returned his gaze back to the four boys in front of him. "I know he looks a lot like Hiei doesn't he? Well, that has a good reason. He is also a Forbidden Child. Like Hiei he is one half koorime, one half fire demon. But, unlike Hiei, he has the ability to use both fire and ice."
Koenma and the others in the room all glanced at Hiei to see his reaction to seeing another forbidden child, but his façade remained as cold as usual, if not more so.
"Undoubtedly, he will first go after the Koorime city and destroy it before going into the ningenkai and wreaking havoc," the infant ruler continued. "He hates all yokai and ningen alike. He does, however, have a near army of demon followers."
He had begun to pace back and forth across his desk while he was explaining what the Reikai Tentei were up against, came to a sudden stop and surveyed the faces of his most trusted detectives. None of them seemed too happy. He sighed.
"As you might suspect, this is one mission that may just be impossible to complete. You, while Mukoro's army guards the Koorime city and Yomi's guards the gates to the ningenkai, will pursue the enemy and attempt to stop him before he reaches either. Mukoro's men have already run into a few of his people along the edges of her territory. Only a few escaped."

There you have it, my first chapter. I need a name for my bad guy, so I would love some suggestions for that as well. -bows- thanks so much for reading the first chapter of my fic. I hope you enjoyed it!
