A strange sensation woke him from his nap. He fixed his green and white striped hat and focused on his sixth sense. He has never felt a reiatsu (spiritual pressure) like this before and he could not quite determine its strength. He stood up and grabbed his cane. "I will go on a walk," he called and left.

He followed the strange reiatsu until he reached a shrine. He looked around. This particular shrine was popular among tourists who came to visit Karakura Town. It was still quite early in the morning and the place was mostly empty. He quickly found the origin of the reiatsu: a girl with long black hair who was talking to one of the shrine maiden. He walked closer, pretending to look at the opening hours for the little shop belonging to the place. He concentrated, determined to get a better read of the reiatsu. It felt warm and friendly, yet there was something wilder hiding behind it, just out of reach. It was not the reiatsu of a Shinigami neither that of a Quincy, of this the man was sure. A voice pulled him back from his thoughts. "Excuse me. The shop will open at 9am." He turned his head and saw the shrine maiden he saw talking to the girl smiling at him. "But in the meantime I can recommend taking a tour of the shrine and the surrounding area. The flowers are quite beautiful at this time of the year." He nodded his thanks and left. The girl with the long black hair had disappeared. He could still faintly feel her reiatsu but decided to leave it at that.

Rei's entire body was covered in goosebumps as she felt something brush against her spirit. She said goodbye to the maiden and turned to leave. Her eyes were drawn to a man standing at the shrine shop. His face was cast into shadow by his striped hat. She shuddered and hurried to get away from the shrine. 'Karakura Town is a peculiar place' she thought. The moment she got off the train her sixth sense started going hay wire. She kept sensing bad spirits but those sensations went as quickly as they came. She was never fast enough to pinpoint them. She pinched the bridge of her nose. She came to Karakura Town this weekend for a short vacation. Her grandfather had mentioned the place a few times. He had worked at the shrine she visited during his youth and was on good terms with the priest. Though, he did call him eccentric. Rei smiled at the thought. Her grandfather was quite eccentric himself. Rei planned to visit the priest while she was here but was told he was currently on vacation himself. She sighed. She asked the shrine maiden to give him her and her grandfather's regards. Rei entered a small café and ordered a green tea. She sat next to the window and watched the streets slowly filling up with people as the town woke up and the stores opened. She nodded to herself. She would not let some weird feelings get in the way of her vacation. She was probably still tense from the events of last month. She nodded again and took out a comic from her bag. She took a sip and started reading.

The man with the hat arrived back at the shop and entered.

"Yoruichi? Yoruichi are you there?"

"What is it Kisuke?"

"I'm assuming you felt that strange reiatsu as well?"

"And I'm assuming you were out checking on it."

Kisuke smiled.

"Spit it out Kisuke. What did you find out?"

"The reiatsu belongs to a girl. Fifteen, sixteen years old maybe. Long black hair. Up closer it felt warm and friendly. But also wild. I couldn't get a better reading. I was interrupted and then the girl was gone."

"Do you think she is dangerous?"

"Difficult to tell."

"You want me to follow her don't you, Kisuke."

He smiled again.

"You know me too well Yoruichi."

"Scientists." Yoruichi laughed. "I'm on my way to stalk a girl then."

"If you say it like this it sounds creepy."

"That's why I'm following her. If you'd follow her she would call the police on you as soon as she noticed."

"You hurt me, Yoruichi."

"See you later, Kisuke."

Around lunch time the next day Rei was more than ready to leave Karakura and its weirdness behind. If she could have taken a train back to Tokyo earlier she probably would have done it. This was not how she expected her small vacation to go. To the strange sensations of bad spirits that came and went since she arrived were now added shadows in the corner of her eyes that were gone when she looked at them, distant screams, and she could have sworn she has seen someone walk right through another person. She looked at her watch. Still three more hours before her train left. She entered the café next to the platform and ordered a glass of iced tea and a slice of strawberry cheesecake. The weather was nice so she took her order and sat at a table outside. She wondered whether she should ask her grandfather if Karakura had already been like this when he lived there. But she decided against it. Her grandfather might be a good priest but he himself had told her several times his abilities were much weaker than her own. It made sense she guessed. She wasn't a normal girl after all. She snorted to herself. Well didn't that sound arrogant. Then she sighed. She'd rather be a normal girl at this point. She had been for an entire month. But she had the nagging feeling that would not last. She shook her head. "Stop it Rei," she berated herself. "This town is making you paranoid. Once you're back home the feeling will pass."

"Meow."

Rei almost dropped her fork at the sudden sound. She looked down at a black cat. For a moment she thought one of her friends had come to Karakura as well but she realized it was just a normal cat. She slowly reached her hand down. The cat inspected it. Then it meowed again and let Rei pet it.

"Well hello there little guy. Did you take pity on me talking to myself?"

The cat sneezed. Rei laughed. The cat stared at the girl and meowed again. She looked at her watch. Half an hour until her train left. She ate the last piece of cake and stood up.

"Thank you good Sir, for cheering me up but I must leave now."

She took her empty plate and glass inside and then made her way to the platform. The black cat was following her. It was quietly sitting next to her until the train arrived. Rei waved the cat goodbye, feeling a little silly doing so, and got on the train. The train started moving after she sat down. She looked out the window. The black cat was still sitting there. Watching as the train left the station. Rei shook her head. Even the cats in Karakura were strange.

The black cat watched as the train left Karakura station. Then it stretched and left as well. It walked through back alleys and jumped from fence to fence until it arrived in front of a shop. A man was sitting on the porch of the building. He looked up from beneath his striped hat and smiled. "Yoruichi. You're back."

"I am," a deep voice answered the man. The cat jumped on the porch and looked at the man. "I understand what you meant when you called the girl's reiatsu weird, Kisuke. I haven't felt something like that before either."

"What do you think she is?"

"That's what I would like to find out."

The man looked up at the blue sky and waved himself some air with a fan.

"I could follow her," the cat said eventually. "She got on a train towards Tokyo. Assuming she lives there I should be able to find her."

"You think you can find her reiatsu, as strange as it is, among millions?"

"Are you questioning my abilities in tracking down people, Kisuke?"

"I would never."

"I am quite curious myself." The cat jumped off the porch. "I'll find the girl."

"Good luck Yoruichi." Kisuke waved as the cat left.

After a few minutes he stood up and stretched. "The world of the living sure doesn't get boring." He smiled while walking back inside the store.

It was Wednesday two weeks after Rei's short trip. Rei and her friends were meeting up in her room at the Hikawa shrine to study together. Though there wasn't much studying being done. Rei was fighting with her friend Usagi over a comic book she took from the bookshelf without her permission. Again. Rei pulled on the tail of one of Usagi's hair buns. "Put it down! I wasn't done reading it! Don't just take other people's stuff without asking first!"

"Common Rei. You know how Usagi is," a girl with long blond hair said. She put down a brush on top of her school book and tied a red ribbon in her hair.

"Are you taking her side, Minako?" Rei shot the girl an angry look.

"I'm sure Minako is not taking any sides." A girl with a ponytail raised her hands slowly in a don't shoot me way when Rei's angry stare met her. "Could you please stop fighting? We wanted to study."

Minako laughed. "Common Makoto. We all knew Amy would be the only one to actually study."

The four girls looked over at their other friend. The girl with short hair looked up from her book and blinked. "If you go on like this you will fail all your tests you know. Especially you two." She pointed at Minako and Usagi. Usagi dropped the comic book.

"Mama will be so mad if I bring back another bad grade. She will kick me out. I will have to sleep in the streets." Tears welled up in Usagi's eyes. "I will turn ugly and then Mamoru won't love me anymore and I will end up lonely and unloved."

Rei let go of Usagi's hair and snatched the comic. Makoto gently pet Usagi's hand.

"There, there. Please don't cry. We will help you study for the tests. Won't we girls?"

Minako nodded but Rei looked outside, a slight frown on her face and the comic book still in her hand. Amy was following her gaze. "Rei? Rei? Hey!"

She turned her head back to the girls. Makoto looked concerned. "Is everything alright?"

"I… Yes. Yes. Everything's fine."

"You felt something, didn't you?" Amy asked, still looking the way Rei did earlier.

"Yes… How… Did you feel it too?"

Amy nodded. "It was very faint. If you wouldn't have reacted to it I might have missed it entirely."

Minako and Makoto were suddenly very serious. Even Usagi stopped crying, though she was mostly looking confused.

"I didn't feel anything. You?"

Makoto shook her head. Usagi looked between Amy and Rei. "What are you talking about?"

Rei looked at the table in front of her. "I didn't want to mention it at first. I thought it was just left over stress from the events last month. But," she took a deep breath, "ever since my trip to Karakura Town I started… sensing strange things. Sometimes I also hear weird distant screams. I see shadows in the sky or in the corner of my eye but they are always gone before I can get a good look. And… I think I can see ghosts now."

Usagi paled. "G-G-G-Ghosts?"

Rei shot her an annoyed look. "Yes. Ghosts. No need to freak out Usagi. They are not the horror movie type of ghosts you are probably thinking of. They look like normal humans. But people just walk straight through them. It seems nobody can see or hear them." She frowned. "And they have a single chain attached to them. In the middle of their chest." She pointed at her own chest. Amy grabbed her notebook and wrote down what Rei said. "Are you sure they are ghosts? They could be anything, maybe a new enemy?" At the word enemy the girls glanced at Usagi. Her lips were pressed together in a thin line and she was staring at her hands. Rei shook her head. "No. They are not enemies. I am sure they are harmless. I don't feel any negative energy from them. Though most of them look quite sad."

"That would make sense." Makoto added. "If they are ghosts."

"I am quite sure they are ghosts."

Amy put her pen down. "I trust your instinct for everything spiritual Rei. But I would also like to make sure. Do you think we could just ask one of those ghosts what they are?"

Usagi looked up. "T-T-T-Talk to ghosts? No no no no no. That sounds scary. I don't wanna talk to ghosts."

Minako laughed. "You'd think after all we've been through Usagi would be less of a scaredy-cat."

The other girls started laughing as well and after a moment Usagi joined too. Makoto pet Usagi's hand again. "Don't worry, Usagi. We won't let any ghosts hurt you. Rei says they are harmless."

"Probably."

"Not helping Rei."

Amy closed her notebook. "It's late already. Let's do it tomorrow after school."

The girls nodded in agreement then looked at Usagi. She was thinking. "Soooo… we're going ghost hunting? In the middle of the day?"

"Yes."

"Well… It is less scary during the day. But if I see anything scary I will run and leave you all behind. I will not fight any evil spirits."

"We won't have to fight evil spirits."

"Ok. I'm coming too."

The next day Rei was waiting in front of her friends' school watching as the students started leaving the building.

"Rei!" Minako waved her hello and Rei waved back. "Soooo. Where are we going ghost hunting?"

"There is this ghost of a woman in the park nearby. I have seen her on my way here, so she is probably still there."

Amy nodded. "Let's go."

They reached the park and Rei led them to a bench next to a small lake. On the bench sat an woman with long dark hair, a few streaks of grey in it. She was staring at the lake.

"Can you see her?" Rei whispered.

Amy nodded. The other girls looked a bit unsure.

"She looks a bit… fuzzy."

Rei and Amy looked at Makoto. "Fuzzy? She looks as clear as any living person."

"Let's get closer. Maybe we can see her better then." Makoto suggested. They went closer. Usagi grabbed Amy's hand. She looked at her with wide eyes. "I have a bad feeling about this."

"She is just a normal ghost Usagi. No need to be scared."

Usagi looked between Rei, Amy and the woman on the bench, who was still staring at the lake, seemingly unaware of the girls. They went closer. Makoto was the first to speak. "Hello." The woman did not react. "Would it be okay if we asked you a few questions?" The woman looked up. She blinked slowly at the girls. "You can see me?" The girls nodded. "Are you… are you dead too?"

"No. We're still… alive." Rei hesitated. "We are kind of new to the whole… ghost seeing thing."

The woman nodded and looked at the lake again. Makoto gave Rei a look and mouthed: "What now?" Rei shrugged.

"Why are you still here?" Minako suddenly asked.

"Minako! I'm so sorry for my friend. She didn't mean to-"

"What? Maybe we can help her pass over!"

The woman smiled. "You girls are very kind." She stopped smiling. "You should leave. Bad things happen around here."

"Bad things? Is that how you died?"

"Minako!"

"Common, if we wanna help her pass over we need to find out how she died. When she was murdered we need to bring the killer to justice! Does she still have some unfinished business we can d-."

"Minako!" Rei hissed. "How can you be so insensitive?"

Usagi squeezed Amy's hand before letting go of it. She walked up to the woman. Rei and Minako stopped fighting and watched with slightly open mouths as Usagi sat down next to the woman. she took the woman's hand in hers. "You shouldn't have to suffer in this world anymore." The woman smiled at Usagi and Usagi smiled back. "You have such a warm and friendly soul young lady." The woman said. A faint glow enveloped her. "They like souls like yours." The woman's voice echoed silently. Then she was gone and the girls watched as a small white butterfly flew away.

"Usagi. Did you send her over?"

"Maybe it was just time for her to go."

"We should leave too." Rei said. "Something is coming."

"Something evil?"

"I'm not sure. It feels different from the woman just now."

Shortly after the girls had left the park, the bench where the woman had sat toppled over with nobody around. The only witness was a black cat.

Over the following days two things happened. The girls started noticing more and more ghosts all around Tokyo and those ghosts started noticing them too.

One day on her way to Rei's place Minako ran into the ghost of a young boy. He was standing at the bus stop with her, making weird faces at the people around him. Minako could not help but snort at a particular funny face and the boy looked at her. "You can see me?" She nodded. With a startled yelp the boy started running. Minako considered following him, but her bus arrived and the boy had already disappeared into the crowd.

The same evening Amy visited her mother at the hospital to bring her dinner. Her mother had to take over a shift unexpectantly as one of her co-workers broke his wrist. On her way upstairs Amy ran into several ghosts, most of them in hospital gowns. They noticed her, but none of them talked to her. When she gave the food to her mother she asked: "How do handle it, when one of your patients dies, mom?" Her mother gave her a sad smile. "By trying even harder to save the next one. But sometimes all we can do, is make their time before they go as comfortable as possible."

While Makoto was grocery shopping she noticed that the chair in front of the small flower shop she liked to visit was not empty. It had been empty for almost a month, after the mother of the owner died unexpectedly. But now the old woman was back, sitting in the chair. Makoto waved at her, a little surprised, then she noticed the chain. "Ah, Makoto." The woman smiled. "It has been a while. You were too busy to greet me these days. I thought you had forgotten about me." Makoto looked around before answering: "I would never forget you, I… I was just busy with school. We had a lot of tests." The woman nodded. "You should study a lot and get a good husband. How are things with the boy you mentioned last time?" Makoto blushed. "Ah… he has a girlfriend already."

Rei learned to ignore the ghosts she met. She felt a bit guilty about it in the beginning but realized quickly that letting the ghosts know she could see them would lead a lot of them to follow her and when they realized she was a shrine maiden they would bother her to send them over or help them resolve their unfinished business. She was not able to send them over and did not want them to have false hope, so she pretended not to notice them until they went away.

Usagi on the other hand, did her very best to avoid every single ghost. She was still scared of them and would sometimes start crying when a ghost got too close. This usually drove any ghosts away but also lead to a lot of stares and whispers from the people around her.

After the events of last few days it did therefore not surprise the girls when the ghost of a high school girl approached them during their Sunday afternoon study session at the Hikawa shrine. Their curiosity turned to worry quickly when they got a closer look at the girl. Tears were running down her face. "Please. Please you have to help her. Please."

"Help who?"

"My girlfr- my friend please. Something. Something is... Please it will kill her." The girl fell to her knees. "Please."

Makoto stood up. "Lead the way."

The ghost got back on her feet and started walking and then running. The five girls followed her for several minutes. They heard a distant explosion and a giant cloud of dust at the end of the street. The ghost was running right towards it. They turned the corner and through the dust they saw a giant six-limbed monster looming over a girl. Where the monster's face should have been was a white mask.

"What the fuck is this thing?"

The monster let out an inhuman scream and closed in on the girl who was frantically crawling backwards.

"We need to transform. Now!"

"Mars Crystal Power…"

"Mercury Crystal Power…"

"Venus Crystal Power…"

"Jupiter Crystal Power…"

"Silver Moon Crystal Power… Make up!"

Yoruichi observed the scene with curiosity. The girl from the shrine and her equally strange friends followed the spirit without hesitation. Yoruichi had felt them getting closer to the hollow and was ready to step in to prevent them from getting killed. Yoruichi was surprised to see that the girls did not hesitate to engage in battle. She was even more surprised when the girls transformed. They were now wearing colourful skirts and white gloves, one of them even had a pair of wings. But what Yoruichi found the most interesting was their reiatsu; it suddenly became much stronger and clearer. This did not go unnoticed by the hollow either who now abandoned its prey for a tastier meal. It attacked. The girl with the red ribbon in her hair grabbed the spirit and dragged her with her, away from the hollow. She told her to get her friend and run. The spirit did. The other girls started their counterattack. A wave of water hit the hollow seemingly out of nowhere, followed but a strike of lightning. The monster screamed. Getting angrier it reached for the girls with its clawed hand. They jumped away with an agility normal humans should not have. The girl with the long black hair summoned a bow and aimed at the hollow's head. A flaming arrow hit it right between its eyes. A slight crack formed in the bone mask. Reaching for its head with one of its limbs the hollow screamed and thrashed.

"Now, Sailor Moon!"

The girl with wings stepped up, holding a long rod in her hand. She aimed at the hollow with a yell and a bright light erupted from the rod. It hit the hollow.

Sailor Moon put all her effort into the attack. The monster let out another of its inhuman screams. With a sudden movement it hit the street hard enough to make the ground shake. Sailor Moon stumbled and her attacked wavered. The monster used the chance and disappeared inside a dark hole in the air.

"Sailor Moon! Are you alright?" Her friends came running to her. She nodded.

"The monster escaped. Why didn't my attack work?"

"Now that you mention it, none of our attacks seemed to have much of an effect on it."

"If anything they made it even angrier."

"We should leave. Before the police arrives. Unlike ghosts, we're not invisible to normal humans."

They left the scene and transformed back. Minako stretched. "I did not expect that I had to transform into Sailor Venus again."

"I said goodbye to Jupiter already." Makoto rubbed her shoulder. "And the bruises. I wasn't gonna miss the bruises."

Amy shook her head. "I knew I shouldn't have left my Mercury computer at home. I could have tried to analyse the monster."

"I kind of expected to have to transform into Mars again," Rei said silently. "Ever since we started seeing ghosts I just knew something would happen."

A sniff turned their attention to Usagi.

"Usagi. Are you alright?"

She smiled but it did not reach her eyes. "I'm starving. Let's get something to eat."

Yoruichi hopped on the train right before the doors closed and immediately went to find a spot to hide. Stowaway cats might not need to pay a fine but they were kicked off the train either way and Yoruichi was not in the mood to walk all the way back to Karakura Town. The trip between the two cities only took a few hours and soon Yoruichi found herself in front of the shabby store again. In the court were two children, a boy and girl with brooms. The girl was sweeping the floor while the boy was swinging the broom like a bat. Yoruichi meowed. The girl stopped sweeping. "Yoruichi. Welcome back! I will go get the boss." She leaned her broom against the porch and went inside. A clashing sound could be heard from within and then Kisuke came outside with wide open arms. "Yoruichi! I missed you. Kids, go inside." The children went inside but not without giving the two a curious look. The man sat down and pointed at the spot next to him. "Take a seat. I am afraid I'm all out of milk though." Yoruichi jumped up the porch and sat down. "That is alright."

"I'm taking you come back with information on our strange tourist."

"Her and her friends."

Kisuke looked at the cat with raised eyebrows. "There are more like her?"

"There is five of them."

"Five of them. The world of the living sure becomes stranger each day." He leaned back and looked up the evening sky. "So tell me, Yoruichi. What happened in Tokyo."

And Yoruichi told.

Kisuke stayed quiet for a while after Yoruichi finished. By now the sun had gone down completely and the crescent moon was rising.

"So there are five people in Tokyo who do not only have the ability to see spirits, but also supernatural powers of their own. And yet those powers did not help them much against a low level hollow."

"From what I gathered these girls only picked up the ability to see spirits after their friend came back from Karakura."

"It is possible for her to have picked up that ability here. Karakura does have quite a dense spiritual energy. The interesting part is how quickly she must have picked it up then."

"And the fact that her friends picked it up from her. But the powers they used against the hollows came naturally to them."

"They must have had them for a while then. You said they transformed? They did not leave their body like Kurosaki does?"

"They were not in spiritual form but after their transformation their reiatsu were much higher."

Kisuke tapped his chin with his fan. "Curious. Very curious. How come we haven't heard of anyone like them. I have to admit I don't keep an eye on Tokyo but people with such abilities must have been noticed by the Soul Society at least."

"The Thirteen Divisions might have just ignored them because they didn't meddle in Shinigami affairs."

"That does sound like something Head Captain Yamamoto would do."

Yoruichi hesitated before adding. "I did hear a name during their fight. I did not sound familiar to me but have more knowledge on strange things than I do." Kisuke stopped tapping his chin and look at his friend. "Do tell."

"Sailor Moon."

Kisuke opened his fan. "Why do get the vague feeling that I should know that name?"

"You're late, Usagi."

"I'm sorry. I had-"

"Detention."

Usagi laughed while her friends sighed.

"You're hopeless without Luna."

"Don't say that Minako. She was just as hopeless when Luna was still here."

"Reeeeiiiii."

"Girls. Could we please start with the meeting?"

"Sorry Amy. What do you have?"

"I put the information we have into the Mercury computer. It is not as much as I would like but here we go." The girls got closer. "I entered both the information about the ghosts we saw over last few days, the monster and how our attacks did not work against it."

"And?"

"Nothing." Amy closed her small computer a little harder than necessary. "I have nothing we don't know yet."

Makoto sat down. "Then what are we supposed to do? How do we defeat these monsters?"

"Maybe we just didn't have enough time? That thing disappeared, maybe the attack would have worked if we had a little more time?"

"No." Usagi shook her head. "I don't think so Minako. I could sense that it was useless."

Rei frowned. "What do you mean by that?"

"You know, usually when I use my attacks-" Usagi put her hands on her chest, right above her hear, "- I can feel the evil leaving the object or person." She dropped her hands. "This time I felt nothing."

The girls stayed silent, each deep in thoughts. With a sudden motion Makoto stood up, startling Usagi making her fall off the porch. "I refuse to give up. If we can't fight these monsters with our current powers, we just have to get stronger."

"Yes. But how?"

"I might be able to help you."

The girls turned towards the unexpected voice. A man in a green and white striped hat was smiling down at them.

"I've seen you before," Rei noticed. "You were at the shrine in Karakura."

"Allow me to introduce myself. I'm Kisuke Urahara. And I can teach you how to kill those monsters."

Hi, I guess this is my author's note.
I have been sitting on this crossover idea for literally a decade and have now finally written the first chapter down. I am trying my best to give you a well written (and grammatically correct) story and hope you enjoy it. Constructive criticism is obviously welcome and desired.
If you're wondering why it's rated 16, it's because Bleach is rated 16 (at least here where I'm from) and the violence and cursing levels will probably be around that level.
