A/n: Chapter 4 of my powerpuff girls story.

Disclaimer: I own nothing except Kai and the characters being introduced in this chapter.

'One down...Two to go...' Kai thought to himself as he stood on the roof of the tallest building in Townsville watching the sunset.

"Hello Kai..." A female voice sounded behind him causing the pigeons on the roof to fly into the air and away.

Slowly turning Kai sighed softly seeing the woman who had tracked him down and forced him to kill the girls. "Well...If it isn't the bitch and her dogs...What do I owe this pleasure?"

"Don't you dare talk to me that way you fool." The woman said and crossed her arms causing her leather trench coat to open a little showing the leather straps covering her breasts and the small leather skirt going around her waist. "If it wasn't for me, you would still be in Alaska in an alley drinking whiskey."

Kai growled as he walked to her, his right hand going to the dagger on the back of his waist but he stopped seeing the two body guards brandish their own weapons of choice. The one on the woman's left wielded a katana with a five foot long blade, while the one on the right wielded a weapon he called a War Hammer.

"I watched you in the fight with Bubbles. You've gotten sloppy." She said as she walked to him, her thigh high sleek leather boot heels clicking on the roof. Kai looked away when she was standing in front of him for a few seconds watching the sky turn dark slowly before looking at her. Her bright blue eyes glowed, as did her auburn colored hair under the rising moon.

"And you've become more of a whore since the last time we spoke." He said, his voice was full of hate for this woman. She only shook her head as she reached up and pulled a few strands of his black hair out of his eyes.

"You have 72 hours left to kill these girls Kai...If you fail, you die." She said before reaching under the collar of his shirt to a studded collar around his neck. "That little thing there will make your head pop right off when I press a little button...And you should consider yourself lucky, this also enhances your fighting ability."

Sighing, Kai took a step back from her and turned back to look at the sky before saying softly, "They will be dead..."

"They had better be Kai. I trust you." She said and smirked before walking back to her body guards. "Kyo, take us back home." She said before there was a bright flash then they were gone.

"Stupid fucks..." He muttered before he sat slowly on the roof and let his head slump a little as he slowly fell asleep.

Meanwhile, in the roof access stairwell, a group of ten SWAT members stood in a tight line, all of them dressed in black and navy blue uniforms and armed with MP5 submachine guns.

"Ok...Intel says Bubbles killer is up on this roof...What we're gonna do is burst through the door and catch him by surprise and open fire. Everyone understand?" A man at the front of the group said as he inched to the door and heard each of them give a sort of grunt as a yes before he kicked open the door and yelled as he began ran through the door and opened fire in short three round bursts on a figure shaped like man and moved to the left so the others could come out.

Gunfire filled the air as the firgure was ripped to shreds from the bullets coming from ten machine guns. Eventually it all stopped when the men reloaded and the one who had spoken before walked slowly to the figure. Prodding it with the barrel of his weapon he watched it slump to the side and grinned behind his face mask as he turned to the other SWAT members and froze seeing a man in a crouch on the top of the casing for the roof access stairwell.

Kai grinned as he jumped into the air and did a small flip and landed in front of the other SWAT members. Brining his hands back he drove the knives into SWAT on each side of him before releasing the daggers from his grip. As the two men slumped to the ground from the daggers driven into their hearts, Kai charged at one of the other men.

The SWAT Kai was charging raised his weapon and tried to fire before Kai grabbed his right arm and twisted violently and quickly broke it before he was thrown off the roof screaming to his death. The next man Kai charged fired shots off that missed Kai by inches but all hit other members of his team before Kai kicked him in the left kneecap causing him to fall to his knees only to have his neck broken.

Five more SWAT were left as Kai pulled up a body in front of him and used it as a shield for the bullets that were now being fired at him. Kai's eyes slowly moved to a cylinder on the body he was holding and grinned seeing it was a flash bang grenade. Reaching up to it he pulled it from the belt loop and pulled the pin before tossing it around the body towards the other SWAT members.

Dropping the body at the sound of the bang, he heard yells as he grabbed one of his daggers from a body and proceeded in killing all but one of the men. When the man was able to see again he winced a little seeing bodies scattered around him. Kai kicked him in the back of the knees forcing him to go down.

"You failed to prevent these men from being killed. You made a mistake following me. And now you pay for that mistake." Kai said before sliding his dagger to the man's throat and slicing it open before picking him up and throwing him over the side of the building to the streets below.

Sighing softly he looked up hearing a soft rumble of thunder and winced when a rain drop fell into his eye before walking to the man he had used as a decoy. Kneeling beside the body he tugged the jacket from him and grinned as he stood and said, "Thanks a lot Professor." Turning, Kai walked to the roof access stairway to leave the building.

Across the town, Blossom stood in the shower slowly cleaning her wounds as the water poured over her. She heard the door to the bathroom open and covered herself as she looked at Buttercup who quickly shut the door and went to their room.

The 16 year old girl sighed as she sat on their bed and yawned after a few seconds. She'd spent the entire day searching for Bubbles killer. She'd seen the remains of her body, all lined up on the floor of the mayor's office. It disgusted and frightened her to no end seeing that someone was finally able to defeat them in a fight.

Laying down, Buttercup yawned softly as she rolled onto her side and heard the phone start ringing on the nightstand. Sitting up she mumbled things under her breath as she moved to the phone and picked it up slowly and said into the receiver "Hello?"

"The Professor is dead….If you wish to find me, I'm in the business district a mile to the east of where I killed your sister." Before Buttercup could say anything the line went dead and she slowly hung the phone up.

"Buttercup? Who was that?" Blossom yelled from the bathroom as she was putting a towel around her body. Walking out of the bathroom she frowned when she saw Buttercup wasn't in their room and a window was open.

A/n: Hope you enjoyed reading this chapter. I have a feeling it sucked a bit, but the next one will be the build up to the fight with Kai and Buttercup, which I assure you will be a long and violent one with many injuries on both fighters. I'll update in 3 days. Maybe 4. Thanks for reading and leave a review if possible. Good night.
