My first attempt at humor. Let me know what you think. I don't own YYH.

NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN

Hiei woke up and couldn't breathe. His shirt felt extremly tight.

He took it off and looked down.

"FOX!"

Kurama ran up the stairs. "Hiei what's wrong?" he said opening the door to the room. Has soon has he was in there he gasped.

"You laugh and I'll remove your vocal cords." said the girl on Hiei's futon.

"Hiei?" Kurama asked. He couldn't help but stare at his best friend.

Hiei's black hair no longer stood straight up. It was has long has Yukina's in fact Hiei looked excactly like his twin except his hair was black and his bangs had a bit of white in them.

"What happened Hiei?" Kurama asked. "Do you think I know?" the fire demon growled.

"Well maybe Koenma well know what's happening." Kurama suggested. He saw the horrified look on Hiei's face.

"No!" he screemed in his high pitched voice. "I can't be seen like this! If the fool and detective see me they'll never let me forget it!"

Kurama smiled and hugged the small fire demon. "Don't you want to turn back into a guy?"

Hiei was thinking hard. Maybe be stuck has a girl forever or have a shot at being a guy and lose all of his pride.

"Well?"

"I'm thinking fox!"

After what felt like years Hiei finally responded.

"You can tell the detective but if you tell the fool I'll kill you."

Yusuke walked to Kurama's house. The fox demon had called him and told Yusuke to come over right away.

Yusuke knocked on the door. Kurama answered. "Thank Enma you came Yusuke."

"Hey Kur- uh Shuichi." Yusuke said. Kurama laughed. "It's all right Yusuke my mother and stepfather are gone for a couple of months."

"Okay what's up Kurama?" Yusuke said has the two of them walked upstairs. Kurama stopped Yusuke right before they got into the room. "Don't laugh Yusuke." Kurama whispered. He knocked on the door. "Hiei are you dressed?" he called.

Yusuke wondered why Hiei was in Kurama's room naked. His mind thought of many things all of them perverted. (This is Yusuke we're talking about)

Kurama opened his door. Yusuke's jaw dropped. Then he began laughing. "Okay nice joke Kurama. How'd he convince you to do this Yukina?"

Hiei growled. "It's me you idiot."

"Can you prove it?"

Hiei tore off his headband. His jagan slowly opened. "You can't fake one of these detective." the fire demon smirked.

"How the heck did you become a chick?" Yusuke asked. He was trying not to laugh.

"We don't know." Kurama replied. "I was making tea when Hiei began screeming and..." Kurama's voice trailed off. "Oh no."

"What?" Hiei and Yusuke asked in unison.

"When there's a spieces that only has one gender they can turn into the oppiste gender when they go into...heat." Kurama felt Youko stir in the back of his mind.

Hiei's face went pale. The koomire would turn into males but since he was naturally born a male he would turn into a girl.

"How long will this last fox?" Hiei whimpered. He didn't want to be a girl.

"I'm not sure. I think we need to talk to Koenma." Hiei began shaking his head. "Or Yukina. It's your call Hiei."

"Fine the toddler."

/What smells so good Shuichi?/ Youko asked. Kurama could hear him growling in a possesive way.

/Youko no!/ Kurama yelled. But he watched helplessly has Youko began walking over to Hiei. (dude I could be so evil and end it there but I won't be able to update has quickly so I'll continue)

"Um Kurama what are you doing dude?" Yusuke asked.

/It's Youko. Apparently Hiei attracts guys when he's in heat. Get Hiei out of here./ Kurama screemed at Yusuke.

Yusuke grabbed Youko. "Look Kurama that's Hiei! He's a guy!" Youko growled and plants shot out of his hair.

A mazako was trying to take the fire demon from him. Youko let out another growl. A more hostile one.

Yusuke groaned. "Sorry Kurama. Shotgun!"

The fox demon was knocked out.

NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN

Me: :Hiding in closet: If Hiei sees this I'm dead. So no one tell him please.

Hiei: What are you doing? :sees computer: Hn. Why are you hiding that?

Me: :Runs away:
