Chapter One: Who The Hell Are You Calling Grandma?

It was relaxing afternoon. The weather was calm and delightful. Breezes danced around the five people walking up the steps to a temple of a psychic known as Genkai. Leading the way was the Spirit Detective Yusuke Urameshi, a regular pupil of the psychic herself. Next to him walked Kuwabara, a tall ugly ape of man with whom Yusuke often used as a punching bag. Behind them were Kurama, Botan and the ever moody Hiei. He was still sulking at having to follow Yusuke and the others for training he felt he could do himself. Of course, Koenma had threatened to shorten Hiei's roaming area of the city or worse, imprisonment if he didn't tag along.

Botan skipped up ahead of them and stopped before Yusuke and Kuwabara. Both men looking at her like she was a weird alien. She laughed playfully.

"She's in a good mood." Kuwabara frowned. Yusuke grunted and continued his ascent of the many steps still before them. He ignored Botan and her perky disposition, leaving Lady Death quite aggravated. After a "Hmpf!" Botan followed along quietly again. She knew what the group was in for, but now she would just simply forget that she knew anything.

Breathing a sigh of relief as he reached the top step, Yusuke stretched a bit and turned to the others. They stopped to listen as he opened his mouth to speak, and as he did, a startling roar screeched in the clearing before them.

"That was not human." Kurama commented before chasing after the others to where the noise had been heard. There eyes were surprised to find a short and slender woman fighting against six demons that were much larger than she was. Two demons already lay slaughtered on the ground behind her.

Yusuke chuckled a bit, watching who he believed to be Genkai once again regaining her youth during the use of her spirit energy. Although her tactics confused the young spirit detective a bit. Her style was slower than normal and it looked as she had made daggers out of pink spirit energy. Shrugging he sat back on the ground and watched the fight continue.

She concentrated on the largest one first. A monstrous and hideous demon that stood at least eight feet tall with blue scaly skin and claws as long as a butcher knife blade. He was no challenge for the woman as she chucked one of her spirit energy daggers into its throat and then sliced its head off with the other.

Kurama glanced at Hiei when he heard him give a short laugh at the violent display of aggression. Hiei shrugged his friend's glance off and watched what he deemed to be a most intriguing match.

Two new daggers had formed in her tiny, thin hands. A smirk playfully danced onto her delicate rosy lips. A shorter, green demon with horns held her arms back and she extended the dagger's length to pierce through the sides of the demon's skin. Flicking a pink curl from her face, she gracefully dodged an attack from another demon. She hadn't seen him coming, but she could sense his advance and she flipped quickly out of the demon's path. The daggers flew again, bursting into bright balls of energy and capturing its victim in a torturous and agonizing death. Again a laugh escaped Hiei's lips.

After disposing of the remaining demons, the young woman rose to her feet and dusted herself off. She turned her attention to the group that had stopped to watch. She narrowed her eyes at the group and her focus rested on Yusuke when he chuckled.

"What the hell are you looking at?" she yelled to the group.

"We were watching your technique, grandma. You seem a bit rusty!" Yusuke replied with a grin. The young woman was not amused.

"Grandma? Who the hell are you calling grandma?" she shrieked angrily. Her blues eyes sparkled with fury, "Come say that to my face jackass!"

"Alright, old hag, I've been needing to stretch my muscles after that long climb up the stairs." Yusuke stretched his arms over his head and cracked his neck.

"Old hag!! You bastard!!" the girl prepared herself for the fight.

"Um...Yusuke?" Kurama touched the spirit detective's shoulder.

"It's alright, Kurama. I can handle this." He smirked confidently. Kurama stepped back and Hiei joined him.

"He has no idea, does he?" Hiei spoke coldly. Once again Yusuke was heading into a battle with someone he knew nothing about, "Hn, it serves him right."

"I don't know who you are, little boy, but you are going to pay for insulting me!" the girl yelled.

"Whoa, grandma, did you forget you memory pills today or something?" Yusuke stood before her. He was still oblivious to the actual truth.

"Don't call me grandma fucking jerk!" she screamed and was before Yusuke in an instant, her fist connecting to the right side of his face. His body was thrown back like a rag doll, slamming into trees before coming to a stop near the top of the steps.

"How long has this been going on?" Genkai stepped next to Botan.

"Just a few moments. Yusuke thinks he's fighting you." Botan smiled, "He's finding out who she is the hard way."

Yusuke was already back on his feet and dodging more fearsome attacks from the lively pink haired woman. His fist connected with her chin in a sharp uppercut. Her small body flew backward and she flipped out of it to land safely on her feet.

"Urameshi don't hit her! She's a girl!" Kuwabara yelled, remembering his honor code when it came to fighting ladies. Yusuke's attention shifted to the loud mouthed monkey boy and a realization hit him when Genkai shook her head disapprovingly. He had dropped his guard and the girl sent him flying with one solid kick to his abdomen. He landed ten feet back from where he had been standing.

"That's enough, Etsuko." Genkai replied with a devious smile, "I think the dimwit has had enough."

"He's lucky you are here because I was this close to beating the shit out of him!" she motioned the closeness with her thumb and index finger. There was barely a centimeter between them.

"Okay, somebody please explain to me what the hell is going on here?" Yusuke rose, his arm clenching the tenderized area of his stomach.

"You idiot! I could have killed you!" Etsuko yelled. She turned from the group and headed into the temple, "I'm going to take a bath, mother! I'll be done in an hour! Stupid demons, my fucking hands are covered in their putrid blood!"

Etsuko disappeared into the large temple. Yusuke turned to face his teacher. His face held confusion and a bit of laughter escaped him.

"Did she just call you mother?" he asked. Genkai narrowed her eyes on the boy and he swallowed hard.

"Yes, numbskull, she did just call me mother." Genkai turned to Botan, "I assume you didn't tell them?"

"After the silent treatment they gave me on the way up here, I guess it just sort of slipped my mind. Oops!" Botan covered her mouth to suppress a giggle.

"You knew about this, Botan?" Yusuke was full of anger. Genkai slapped his face, "What was that for, Genkai?"

"Etsuko was right! You are lucky she didn't kill you!" Genkai turned and stormed off, stopping only once to motion for them to follow.

"Why didn't you tell us you have a daughter?" Yusuke asked, rubbing his cheek and walking alongside his mentor, "How old is she?"

"I didn't tell you because it wasn't your business and she's seventeen." Genkai snapped, "You'll each have your own room while you're here. I suggest you take tonight to relax. Tomorrow all five of you will begin excessive training and I don't tolerate slackers!"

"Um...five of us?" Botan asked meekly.

"Not you, Botan. Etsuko will be training with the boys." Genkai replied, "And lose your honor code about hitting girls, Kuwabara. You will be facing off against Etsuko at times and she won't take the match lightly."

"What? I'm gonna have to hit her?" Kuwabara was shocked.

"Don't be a sniveling crybaby!" Genkai yelled, "I won't tolerate that either."

"Then this shall prove to be a most interesting visit, Genkai." Kurama smiled politely and followed the others inside.
