Yukina's Alter Ego

On mission in Human World, the girls are trying to catch are trying mutant toad that was trying to steal a comic book. The toad mutant is hopping fast but Kiri and Yukina gets in front of the other girls and they both get the toads legs and pulls him down causing him to drop down so hard that awning from a store they were under falls on top of the toad mutant, Yukina and Kiri. The girls gasp.

"Yukina! Kiri!" Botan says as the girls get the awning and the poles with it off Yukina and Kiri.

"Are you two ok?" Keiko asks.

"Yeah, I'm ok." Kiri says.

"I am too." Yukina says. "But I don't remember who I am."

"You're Yukina the Ice Maiden." Ninji says confused.

"I am or am I super heroine."

"What?" The other girls say confused.

"I am Ice Maiden the heroine who stops crime." Yukina states strongly.

"Yukina, are sure you're ok." Sashe asks.

"I must find me a costume to wear." Yukina says running off.

"What's going on with, Yukina?" Shizuru asks.

"I think she suffer from a case of amnesia." Tami answers. "That awning hit her harder than it hit Kiri and that toad."

"What do we do?" Kiri asks.

"Well, let take the toad to Spirit World and asks Koenma and oh boy what are we going to tell Kazuma." Sashe asks.

"Well, let's find out." Ninji asks.

The girls get the toad and drag him to Spirit World. They soon drop off the toad and go to Koenma's office. They explain to Koenma the situation. Koenma rubs his chin in confusion.

"Well, this a problem." Koenma says.

"Yeah, and we don't know what do or how to tell Kazuma about it." Kiri says in worry.

"Tell me what, Kiri." A voice asks.

"Boys!" The girls say seeing their boyfriends.

"Well, Yukina has amnesia." Tami says.

"What!" Kuwabara says in worry.

"After we caught the toad mutant, Yukina started to act like a superhero."

"A superhero?" Mikey asks. "Girls, I think I know how to solve your problem."

"How, sweetie." Kiri asks.

"Well, if Yukina thinks she a superhero then you girls could be her super team. And we can be the bad guys to make think that she is stopping crime with guess who as the leader."

"Kazuma!" The girls say.

"What! I'm not wearing a costume!" Kuwabara says. "But I'll do it to help Yukina."

"Big guy, you don't need a costume…" Mikey says.

"I can't transform on command, Mike!"

"Well, isn't it the night of a full moon and a certain sound can be heard by you only."

Kuwabara groans and he and the other boys go along with Mikey's crazy idea. The girls go to find Yukina at the costume store finding a costume for her self.

"This is perfect." Yukina says.

"Ice Maiden, we just witness a crime being committed." Kiri says in her boyfriend's costume.

"Who are you?" Yukina asks.

"I am the Turtle Avenger! These are your teammates, The Swordswoman, The Archeress, The Mighty Silencer, The Spiritwoman, the Tough Retaliator, and Brain Girl." Kiri replies as she points to Botan who is wearing a female version of Hiei's Dark Tournament outfit with the cloak on top. Then she points to Shizuru who is wearing a female archer's outfit. Then she points to Sashe who is in female ninja outfit. She points to Keiko who is wearing and female version of Yusuke's Dark Tournament outfit but with sleeves. She points Ninji who is wearing a female wrestler outfit. She points to Tami who is wearing a lab coat.

"That's wonderful and here's my costume." Yukina says as she is wearing female Chinese fighter's outfit. "What is the crime?"

"An evil master minds plans over run Spirit World with his army of villains." Kiri says.

'Then let's go, girls."

The girls follow Yukina to Spirit World where the ogres have been tied up and Koenma and George tied together. Yukina gasps in horror as the other girls follow her to Koenma's office his chair is turned around and a deep voice laugh from the chair.

"Who are you, villain." Yukina asks the voice.

"Well, Ice Maiden, I'm the one who will destroy you." The voice answers sinisterly. "I'm Dark Bull!"

The chair turns around to see a dark oxbull with glowing white eyes and a scar is across his eye. The girls gasp and more villains come into the room.

"These are my villain friends: The Dark Ma-zoku, The Fox Thief, The Fire Swordsman, the Ninja Slayer, The Mad Scientist, the Crusher and Titanus Turtle." Dark Bull says as he point Yusuke, Kurama, and Hiei who are in their Dark Tournament outfits. He points to Leo who is wearing ninja outfit. He point to Don who has lab coat and beakers in his hand. He points to Raph who is wearing a wrestlers outfit. He points to Mikey who is wearing a white version of his Turtle Titan outfit.

"We'll stop you, Dark Bull." Yukina says.

"I'd like to see you try." Dark Bull says.

The guys and girls charge at each other to start a fight while Yukina and Dark Bull clash with swords. Dark Bull is impressed at Yukina sword skills.

"Wow, Yukina's good." Dark Bull says in his head as Yukina shot an icicle at Dark Bull. "You missed!'

They continue to fight as and the girls pretend to defeat the boys except for Yukina who is still fighting Kuwabara who is still Dark Bull. The icicle that Yukina shot is on the ceiling about to fall on her. Kuwabara sees it and pushes her out the way, which makes her fall on the floor enough to hit her head again. Kuwabara goes to Yukina.

"Yukina!" Kuwabara says in worry as the others go to her as well.

Yukina gets up and rubs her head. She looks at everyone and is confused that they are in costumes or outfits from the Dark Tournament and she looks at Kuwabara who is in his oxbull form.

"Kazuma, why are you in your oxbull form." She asks nicely.

"Well, we were having a costume party I didn't have a costume to wear." Kuwabara replies smiling.

"Oh, this is why I'm wearing this costume." Yukina says looking at herself. "Well, let get back to the party."

So the girls and guys have a costume party with each of the girls kissing their boyfriends making them blush.
