Kaoru didn't know how to feel about these letters anymore. Something was telling her that the person who wrote this knew what he was up against and if he would come, he would come prepared. It made Kaoru very self-conscious. The family's reputation and the number one top wrestler in the world didn't seem to have any impact on this criminal.

Kaoru remembers the time when her father wrestled against Panda in the wrestling ring. He was influenced by HIM at the time but still her father was able to beat the Panda. This made him the only person who was strong enough to defeat someone influenced by black energy without super powers.

Kaoru shook her head as now other wrestling matches off her dad came along in her mind. She needed to concentrate on her crying mother. Kaoru now quickly comforted her mom and called her dad to come home immediately.

It took around 5 minutes for her dad and Brothers to arrive home. Her father was stressed out and really worried. He was pacing down the living room as he read the last letter over and over. Even he didn't believe someone was stupid enough to actually go through with this, but now he was seriously beginning to doubt that. Maybe this person did knew what he was up against, what if he did got his hands on his children. Kaoru's dad would be crushed if something happened to them. He then sighed and looked at his family. ''What do you guy's think?''

Kaoru looked at her brothers and mom but no one responded to her dad, so she did ''I don't know if they can actually come after us, I mean we are strong enough to go against a whole army''

Kaoru's brothers confirmed with a nod and her mother seems to gain strength from her words. Her father expression on the other hand didn't change. He looked just as concerned as before. '' But what if?''

Kaoru now stood up in front of her father and said ''El Gato told you to never give up and you aren't going to give up now. If they do catch me, what is impossible by the way, I want you to not give in and follow you dream of retirement.''

Kaoru's dad now smiled and gave her a crushing hug. ''That's what I admire about you . You're strong, wise and caring.'' Then he loosened his grip and Kaoru was free to breathe again. ''My little Buttercup, always giving me extra power to overcome my strongest opponents.''

Kaoru smiled but she wondered like many times if her father knew about her secret identity. He often called her Buttercup but she still didn't know if it was a nickname or that he actually knew she was the Powerpuff Buttercup. It made her sigh in relieve that her parents couldn't read her mind.

Another reason why she was happy they couldn't do that was because they could also see her worries. There was something about these letters that was disturbing. But not as disturbing as the fact that someone had been able to place the letter on her back without her noticing it. It meant that they could use the element of surprise against her and she didn't like it.

Kaoru looked at her parents as they began to speak and asked her and her brothers to go to their room. Kaoru complied and went up to her room. She could probably relax and forget about those letters so she didn't mind.

But coming into her room she noticed something was off. Like something had been moved in the room or there was something new. Kaoru looked around. Her closet was the same, her desk was he same and her bed was the same. Well, not every part of the bed. There was an envelope on the pillow.

Buttercup looked around if no one else was in her room as she went toward the envelope. She then opened the letter and sat down.

Hi Kaoru,

I am going to keep this letter very simple. If you don't convince your dad to retreat his status, we will come after you. You don't scare us one bit and you know why?

We know how you act,

We know how strong you are,

We know where you go,

And we know everything other thing about you dear Buttercup

Kaoru now swallowed as she read the letter. This person was defiantly crazy if he actually knew all of this and still wanted to go against her as a heroin, her family and the number one wrestler in the world. The thoughts made her tremble a bit, she was not used to be confronted like this. She could handle any physical attack but these letters where different. They were like mini psychic attacks, influencing her thoughts and happiness.

Kaoru looked outside to see if there was any sign of burglary but she couldn't find one. So the only way someone could have come in was from the front door. Buttercup now stood up and walked out her bedroom, downstairs to the front door. It was locked with five locks since the treats so no one could have entered from there. It made Kaoru realize that it was probably a stupid prank of one of her brothers. She then walked back to her room and laid down on the bed again. Still something was off. Her brothers didn't know she was Buttercup right?

Suddenly Kaoru jumped up as something vibrated in her pockets. She soon realized that it was her phone and she picked it up. Apparently it was Momoko, she had called to come together at the lab after dinner this evening. Kaoru agreed and hang up the phone. She looked at the letter on the other side of her bed and grabbed it to read it again. She then folded it and pushed it in her pockets. If someone was threatening not only Kaoru but also Buttercup, then Momoko and Miyako needed to know.

Later that evening all three girls meet at the professors lab in their super hero form. Ken, Poochi and the Professor where on one of the TV-screens as they were still in hiding. Blossom, Bubbles and Buttercup all seated down at a half round table as the professor displayed his findings and the reason off their comings. ''I have finally found the reason to why everyone who has been hit by the black Z ray's before, now has the same or more power without het black ray's.

It seems that the Black rays have unleashed their inner Black side. So when HIM took away their Black Z ray power, their…let's say hearts…..began to unleash their own black powers to compensate the loss of the Black Z rays. This new power is much stronger than the Black Z ray's as we have already noticed the past years.''

The professor now walked away and looked at his experiments. '' I think I finally know how to cure them, but I am not sure if it is going to work. That's why me and Ken wanted you three to go and catch us the frog that Momoko had kissed before. I can test my theory on him and if it works, you girls can use it for the real bad guys like the Ganggreen gang.'' The professor then turned away from his experiments and looked at Ken. Then ken began to talk ''Speaking of which, the Ganggreen Gang has just been reported. They have broken out of prison again, so be an guard at all times''

All three girls nodded in agreement and the professor disconnected their connection. The longer they were chatting the higher the chances where that someone could trace their location and so it was for the best.

With the TV's now off Buttercup turned to Blossom and Bubbles. ''Before we go looking for the frog, there is something I need to show you.'' Buttercup now picked out the letter from her pocket and gave it to the two other girls. ''My dad got another letter but this one is directed to me''

Blossoms eyes widened more at every word she read while Bubbles stayed to calm and quiet. Buttercup decided to speak before her friend could answer ''This means more people not only know my identity, but also aren't afraid off going against me and my super power''

Blossom and Bubbles nodded in response. They were also beginning to fear that maybe it was indeed going to happen. Blossom took out a paper in front of her and gave it to Bubbles. ''Bubbles I want you to write down all names that we know that have been influenced by the black z rays. I have a feeling that the person who is threatening Buttercup has encountered us before.''

Bubbles had now written down a lot of names and the list contained every criminal they had encountered before. Buttercup and Blossom began to sum up why certain criminals couldn't be involved. ''We know they are with more than one so we can cross away everyone who works alone'' Buttercup then thought further ''We can cross off the Ganggreen gang, they were still in prison when I got the first few letters.'' Blossom now stared at Buttercup and said ''That only leaves the Rowdy ruff boys I think'' Bubbles shook her head ''No, we also have the Amoeba boys''

Blossom began to think about them. She hadn't seen them in three years or so? ''We have only fought them once and I believe they left town after that new Casino was built on top of their old hideout. We haven't seen them in years, so if we cross that one away that leaves us to the boys again.''

Buttercup now stood up and looked outside the window '' I don't believe it's them, If they would have known my true Identity they would have gone for the kill instead of using me to bribe my dad''

It was true. The Rowdyruff boys Z where the most trouble for the girls. They were very active bank robbers in the New-Townsville. Most of the time they were equal in strength or the boys were stronger. So they were a big pain in the ass. They didn't only have new attacks, they also had normal and special guns now. The special ones where only for fighting the Powerpuffs. They were meant to take away the powers of the victim temporally. Luckily for the girls they found out just in time and know how to avoid those guns now.

''Buttercup is right, they wouldn't have passed an opportunity to kill one of us if they had the chance'' Bubbles said as she looked up from the paper. ''Maybe it's someone else, someone who has seen you transform but doesn't really know how much strength you have''

Buttercup now sighed and turned towards her friends ''I hope so, because I told my dad if something would happened, I never want him to give in. Even if that means I will not see him ever again.''

Blossom and Bubbles now stood up and gave Buttercup a hug, who accepted it reluctantly. ''I will be fine! It can also be a prankster or my brothers that are playing a trick on me. Besides no time to worry now, the World Cup is on TV so I am not leaving the house so much''

With that said Bubbles and Blossom where satisfied again and everyone went home for the night. The next day they would come back and search for the frog. Where ever it had gone to.

Buttercup flew in her room and transformed back to Kaoru. Kaoru walked to her dresser and opened a drawer to put in the letter. She couldn't shake off the feeling that something was very wrong about that letter.

Since everything in her room now remembered her about that letter, she walked towards the living room to ease her mind. On the couch where her dad and brothers watching TV. There was a recap of the soccer matches between The Netherlands and Cameroun form 2010. It wasn't that spectacular and she had seen it before so she walked to the kitchen instead.

In the kitchen her mom was looking through the rest of the fan-mail. The last couple of day's where hectic with the enormous amount of fan mail, but still the whole family helped writing back. It was almost getting a tradition. Kaoru rolled her eyes at the amount of fan mail when suddenly her mom gave her a letter ''It's for you''

Kaoru took the letter but before her mom was fast enough to respond with all kind of girly questions Kaoru was already in her bedroom again. Was this going to be another letter from them? It was very fast after getting the previous one.

Dear Buttercup,

You get until the end of this evening to get your father on our side or else we will give you a warning as in a preview of what is going to come….

I hope you understand our drastic measures

Kaoru looked around her room one more time. She knew the person who had wrote this wasn't in this room but it felt like it. It was giving her the chills. Besides that, what the hell could they do? The worst thing they could do is reveal her super hero identity but if they did that then her whole family would be in danger. Even her father and if he died those guys wouldn't make any money from it. So going public with her identity was not their plan, but what was? Kidnapping her little brother? Then why did she get these letters? Kaoru had to admit she had no Idea who she was facing and what they were capable of. There was only one thing she knew… she didn't want her dad to give in no matter what was going to happen and with that in mind Kaoru fell asleep almost peacefully.

When Kaoru woke up the next morning she laid down on her bed for a little longer. Staring at the sealing she began to wonder what would happen today. If the letter writers really meant business she was going to find it out within the next 24 hours.

Kaoru now jumped out of bed. She was free from work today, her friends where only coming over after their (university) classes and she had the house to herself. So watching sports and eating unhealthy stuff was on the agenda. It was only wen Kaoru walked to the bathroom when she noticed that something was off. Like she was missing something.

Kaoru turned around but nothing was missing. Strange, very strange. Kaoru now shook her thoughts away and focused on taking a shower. She took of her sleeping shirt, pants, shorts…wait wasn't she forgetting something?

Kaoru looked down to her waist in a state of shock. Her belt was gone. She always slept with it and now it wasn't around her hips anymore. Kaoru pushed her sleeping shirt back on and rushed into her room to look for it. Underneath the bed, in her bed, under her pillow, in the dresser and on or in her desk. Everywhere she looked it had the same result. Her transformation belt was gone.

Kaoru now began to fear the worst. Was this just coincidence or had the letter writers taken her belt away? She was much more vulnerable if she couldn't transform so if it was really them it had been a good move.

Luckily for Kaoru she could also kick butt without it, just not in the same degree. Kaoru sat down on her bed with her hands in her hair. She needed to do something about it but she didn't know what. Kaoru then took the phone and called Momoko and Miyako to tell them what had happened.

Of course the girls were surprised and a bit in shock. Not only did someone know who Kaoru really was, they also knew that she needed that belt to transform to Buttercup and that was not good news. It meant a new weakness, something all their enemies could use against them if they found out. Kaoru always slept with the belt on, and now her belt was stolen both Momoko and Miyako feared for theirs.

Momoko and Miyako came over after their classes, to comfort Kaoru but instead Kaoru just got mad . She wanted to kick someone's ass and make him pay. Her friend were understanding and asked her to cool down. There was nothing they could do about this. They had no clue on where or who to look for. Kaoru hated it but she knew her friends were right. She then focused on the TV with a lot of reluctance and that reluctance only grew when Momoko and Miyako got called to fight a monster in the city.

Kaoru hated it already especially because while her friends were fighting the monster, she needed to look for that damned frog. Kaoru stepped outside to walk towards the park. She didn't know if the frog was there but she couldn't go looking for it around the professors lab. That would be suspicious to Buttercups enemies so that would not be a good move.

Kaoru sighed at the thought of looking for the slimy thing when it also began to rain. Now Kaoru had, had it. This day couldn't possibly get any worse could it? She walked with her face held down towards the park. It did her good to see children play in the water puddles and she began to smile again. She even saw Anika, Xzavier and kevin and asked them to help search for the frog.

After on hour the raining stopped and the kids came back with frogs, a lot of frogs. But none of them was the frog she was looking for. Kaoru thanked the kids and decided to play a game with them.

Everyone took one frog and place it on the line Kaoru had drawn. Then they counted to three, released the frogs and the one to reach the grass first was the winner. Kaoru enjoyed it that all three kids were yelling for the frog they chose.

Kaoru was about to call Xzaviers frog the winner when suddenly a foot stepped in his frog, crushing it underneath. Kaoru looked up to face the bastard and tell him a piece of her mind. It was then that she saw who it was.

Bobby Green, leader of the Ganggreen Gang. Kaoru grabbed towards where her belt usually was but she realized soon enough that she didn't have it anymore. She cursed lightly about it and that gained the attention of Bobby.

Bobby looked at the direction of the cursing and saw Kaoru and the three children. Bobby smirked amused at the small boy as he saw he had ruined their game. ''Aww, did I crush your little frogy'' Bobby said to Xzavier as he saw the disappointment being replaced by fear.

Kaoru wanted to stop ace right there and now. She looked around. No other gang members insight. That was good in Kaoru's mind. This means she had a change off beating him if a fight was going to break out.

Kaoru now stepped in front of Xzavier which caused Bobby to focus on her. ''Leave them alone'' Bobby 's smirk grew larger ''Or what? You're going to call the Powerpuffs? They're to busy kicking monster but to come and help you''

Kaoru didn't move and focused on the children behind her. ''Xzavier, take Anika and Kevin and go home now!'' Kaoru didn't move her eye's away from Bobby. She knew from fighting him as Buttercup that, that was not a good move.

Bobby came closer as Kaoru now got into the fighting position. ''You're going to fight me yourself?'' Bobby said as he laughed at her. Kaoru had enough of him and the moment he came to close was the moment she kicked him.

Bobby seemed to be surprised by her strength as he stepped back from the impact. Bobby was a bit irritated now, but also It was a big turn on for him. He had never met a woman without superpowers that would face him. It was something that made his heart race.

He then placed an evil grin on his face ''I will show you what happens if you mess with me''. Kaoru now feared for her life as she thought he was going to use his razor sharp cards to attack her. But instead he kicked her back. Kaoru didn't expect that and was quickly pummeled to the ground because he did have super powers.

Kaoru was now laying on her back in the grass. She looked up to face Bobby as she saw him coming closer to her ''Babe, You can call me Ace and all I want is a date with you.''

Kaoru looked shocked and yelled ''No way!'' Kaoru then attacked him again. Kaoru was indeed a master in martial arts but Bobby/Ace had learned how to block or counterattack them by fighting Buttercup on a regular basis. It made it harder for Kaoru now to win this fight.

Kaoru was suddenly pushed against the ground again as Ace jumped on her. ''Come on one little kiss then'' Ace said as he came closer and crushed her cheeks between his hands. Kaoru felt his breath against her lips, making her go on survival mode and smack him in the head. She had hit him so hard that Ace fell off her onto the ground.

Ace seemed to be temporarily injured and so Kaoru took her chance and ran. She ran across the park, took a sharp turn once out of the park and so she raced home. She did look back a couple of times but Ace wasn't following her. She had probably been too fast for him.

Wen Kaoru finally entered her house she was out of breath. She had run for 10 minutes strait at a pace that was only possible thanks to the adrenalin in her body. ''Note to self, Do not come near Ace or Bobby in normal identity.'' Kaoru mumbled as she took out the phone to call Blossom and Momoko to tell them what had happened.

The week from then on went by fast and before Kaoru knew it, it was already Saturday. Kaoru's thoughts were now a bit more messed up than before. She was happy that she hadn't seen Ace anymore and she was disappointed/angry for the fact that she didn't found/got her belt back. But the most disturbing thought in her mind was those of the letter writers. They had said that her dad needed to comply before today and her dad hadn't done that.

But what was even more creepy was that the letters had stopped coming after her belt had disappeared. Like they had never gotten the letters in the first place.

Kaoru sighed as she saw her group for the skateboard lessons walk in. It was good that she had some distraction here and she was able to focus on other more happy things. That was until her lesson had ended.

Now only Anika and Kaoru remained on the skating grounds. Kaoru had promised Anika to help her get a higher Ollie and so she give her a private lesson. ''Now, For a higher Ollie, try pulling your front foot closer to the tail. If you put it over the middle point of your board and jump higher, your Ollie will also be higher. ''

Anika smiled at Kaoru as she finally accomplished making a much higher Ollie then before, but her smile soon faded away as she went from happy to looking scared. Kaoru noticed it and saw that Anika was actually looking at someone behind her.
