I don't own Yu Yu Hakusho. The events listed below follow the storyline of the manga in which Yusuke returned to Human World one and a half years instead of three and runs a ramen stand with a start-up loan from his mother.

Chapter One- The Strange Case

"One Urameshi special!" Yusuke said as he put the bowl on the counter and accepted the payment. He turned to punch it in while keeping an eye on his red-haired boyfriend. He had been surprised to come home to Human World and find that his sexual preference had changed. For years, he had been crazy about Keiko, though his perverted side kept him from expressing it properly. He finally got serious when he was preparing to go to Demon World. He told her they would get married when he came back in three years. Well, he ended up returning after only a year and a half. The first ones he surprised were Kuwabara and Kurama.

Kurama carefully blew on his food before putting it in his mouth. It was delicious as usual. Yusuke had a flare for cooking, no denying it. Kurama had been content to not marry for he knew he would eventually return to Demon World for good. He wasn't keen on the idea of raising a human family as they would keep him in Human World, not that he didn't like living here. He loved it, especially when he found that he loved Yusuke. When the part demon surprised them and the two of them locked eyes, he felt his heart flutter. He could see the shock in Yusuke's eyes and waited until they were alone before asking, "Do you feel the way I do about you?"

Yusuke had nodded. "Yeah. Really, it's surprising. I never thought I'd fall for a boy."

"Neither did I," Kurama had admitted. "But when I looked into your eyes, my heart fluttered and I knew then that I loved you."

"My heart beat for a moment when we locked eyes and it shocked me when I realized it was because I love you."

Kurama had put his arms around Yusuke's waist while the other had put his around the neck. Green eyes stared gently into brown and the redhead knew in that moment that he and Yusuke were meant to be together.

"You will have to break the news to Keiko," Kurama had said softly.

"Yeah. She'll either understand or she'll scream and beat me up."

"If it's the latter, I'll patch you up."

Kurama returned to the present, eating his ramen and watching Yusuke run his business. Keiko had been mad when Yusuke broke up with her, but when he said he fell for Kurama, her ire faded and she accepted that Yusuke's heart now belonged to another. That had been three weeks ago and both boys couldn't be happier. Kurama knew he would have to tell his family about his involvement with Yusuke. Mother will may want to meet with him and find out how serious his relations with me is.

"Well of course she will," Yusuke said when Kurama mentioned it. "She wants to make sure that I'll treat you right."

"I honestly cannot imagine you being anything but nice." He put a hand on one of Yusuke's. "I should go. I have school tomorrow." He stood and left with a smile. Yes, his mother would want to know and should know. She met Yusuke when she thought he was a friend and now, he was his boyfriend. Mother will like him. He may be a little rough around the edges, but he is still a nice guy.

Yusuke tossed up another ramen order as he watched Kurama leave. There was still another year and a half to go before Kurama graduated high school. He had already revealed that he would work for his stepfather's company after high school. That was fine with him; he had his ramen shop that provided him with the money to live on his own.

Except I'm not really alone. I live with my mother and I have a loving boyfriend who is like me: Part human and part demon. It's no wonder we got together. He also helps me from time to time with the occasional detective work that comes up.

"Yusuke Urameshi?" came a rasping voice.

The raven-haired teen turned to the counter with his winning smile. 'Yes, sir! What can I get for you?"

"Your detective special," he said.

Yusuke's smile vanished and he quickly looked around to see no one nearby. Only demons and Spirit World knew that the secret phrase, "detective special" was for when they needed his skills as a supernatural detective. Such times were few, but some demons were revealing themselves to the human race. Luckily, those demons were benign. "All right," he said at last. "Wait for me by the door." He pointed to the side of his shop. The demon, wearing a hooded sweatshirt, nodded, and moved off while Yusuke closed up shop. He went to the door in the side of the shop, opened it, exited, and locked it before looking at his client who kept his appearance hidden by the shirt, pants, and sneakers.

"All right, what's the problem?"

"I've heard rumors of demons and humans being forcibly changed into the opposite gender. If the ones responsible aren't stopped, they may switch a demon's race with a human or vice versa, maybe even experiment to create demon-human hybrids."

Yusuke frowned. "Rumors, huh? Think you could lead me to where rumor says these gender switches are happening?"

"Of course. Please follow me." The demon set off down the sidewalk with Yusuke following behind him.

The depilated house seemed empty and unassuming. Naturally, Yusuke did not assume that it was not the place where experiments were taking place. "Well, I'll check the place out. Thanks for the tip-off." Yusuke headed toward the house and was soon through the door less front entrance. He carefully scoured the first floor to find it empty and then checked the second floor and attic. Both floors were empty and he headed down to the basement. He reached the door and pressed an ear to it. He heard nothing and slowly opened the door before cautiously moving down the stairs. When he reached the bottom, he reached into his jacket, extracted a small flashlight, and switched it on.

The room definitely had the look of a lab. There were tables with beakers and tubes of different colored liquids covering every inch of surface space. There were to chairs with connected helmets on the other side of the room. That definitely hints of switching demons or humans. Looks like something out of those horror movies where mad scientists would switch the brain of a human with a monkey. Yusuke was tempted to blast the evidence but who knew what those beakers and tubes contained and he didn't want any of them to splash onto him. He then spied a drain on the floor and grinned. Yes, I'll pour them down the drain. I just hope all the water and sewage underground dilutes this stuff.

"Find anything?"

Yusuke whirled around, finger pointing at the doorway, and saw the demon who led him here. He holstered it as the demon came down and continued, "I was wondering if you found…anything." He stared at the setup. "Guess you did."

"Yeah and I intend to dump it down the drain." Yusuke pointed at said object. "Care to help?"

"Sure." For a time there was silence save for the sound of liquid pouring into the drain. Yusuke sank into one of the chairs after he poured the last of the beakers down the drain and sighed with a grin. "Well after I blast these chairs apart, that will be that." He got up, walked a few feet, turned, and used a controlled amount of energy to turn the setup to bits of wood, plastic, and wire. "Case closed."

"Great, that's really, whoops!" the demon had come over with a tube of liquid to pour it down the drain, but tripped over his tail that had come out of his pants and the liquid splashed on Yusuke.

The teen sputtered as some of the liquid went down his throat; not a lot, just a few drops. He wiped his face clean and shook his hands clean as well.

"Sorry," the demon said. "Are you okay?"

"I think so. I swallowed a bit of it, though.'

"It looks like your skin absorbed some of it, too."

"Looks like it didn't do anything. Well, let's go." The pair left and split up. Yusuke headed home to sleep after successfully closing an easy case.
