Chapter 5: Change

Three days have passed since the meeting with Ichigo and his friends. Conan truly had no idea what he had gotten himself into this time and he speculated that this would be a big change for him. After he got up, he dressed himself and started for the kitchen to get breakfast, he remembered the words that Kisuke had said. "Three days from now, be ready at the Kudo household with your bedroom window open." Those words stuck to him, he wandered wondered who Kisuke really is was.

"Conan-kun!" Ran's voice pulled him out of his thoughts.

"Yes, Ran-neechan?"

"Are you sure you're okay to go to school?" Ran asked, concerned.

"Yeah! I feel great!" Conan cheered with a smile.

"Alright, but if you're in pain just tell me, okay?" Ran said.

"Hai!" With that Conan and Ran started to get ready to go to school. As they walked he Conan met up with his friends and they asked him what happened to him.

"What happened, Conan-kun?" Ayumi asked.

"Yeah! What happened to you?" Genta added.

"I got hurt, but it wasn't too bad." Conan said, almost sheepishly. "Don't worry about it."

"Is that so..." Ai questioned skeptically.

"Yeah, that's all. Come on guys, we have to go to school or we'll be late!" Conan said. With that, a normal day of school began for the Detective Boys.

Elsewhere

When lunch rolled around, Ran was eating on the roof when her phone went off. She pulls out her phone and looks at the text. It was Sonoko who said that she was sick today, she said and that being sick sucks and she doesn't like it. When Ran put her phone away, she heard someone behind her.

"Hey!"

"Yes? What can I-" Ran stops and looks at the person in front of her. The person was transparent and had a broken chain on his chest.

"Y-Y-You're a g-g-g-ghost!" Ran stammered, trembling.

"Yes, I know I'm dead, which sucks. I hoped that-" Ran screamed and ran away as fast as she can down the stairs of the roof. "You run away and not won't hear me out..." The ghost sighs wearily. "After finally finding someone who could see me, too!"

After running to the restroom, Ran washed her face and looked into the mirror with a deathly pale color on her face.

"I didn't see it. It was just my imagination..." Ran said trying to catch her breath. She walked out of the restroom still feeling a sense of terror. Just then, someone called her again.

"Yo, Mouri." It was Ichigo.

"Hello, Kurosaki-kun..." Ran said with a shaky voice.

"Oi, are you okay?"

"I… I just need to lie down for a while." Ran kept shivering, eyes darting about as if there were ghosts everywhere.

"Come on, let's get you to the nurse's office." Ichigo began to helps Ran towards the said office.

"What's wrong, Mouri-san?" Ran didn't know what to say to Araide's question. She couldn't say see she saw a ghost, it would make her sound nuts.

"She's having a panic attack." Ichigo replied when the karate champion didn't. "She's displaying all the signs."

"I see..." Araide checks Ran for the symptoms. "This looks a one, just rest for a bit and you will you'll be better in no time. I have some things to do, I'll be right back." The doctor walked out the door leaving the two teens alone.

"I have to go check something. Will you be alright?" Ichigo finally said after a few moments of awkward silence.

"I'll be fine, Kurosaki-kun. Thanks for helping me." Ran gratefully said.

"No problem, I'll see you later." Ichigo gave a small smile and left.

"Hey Ichigo, where's Mouri?" Rukia asked when Ichigo entered the classroom.

"She's in the nurse's office, a spirit tried to haunt Mouri." Ichigo grumbled, annoyed.

"What?" Uryu's eyes widen, concerned. "She didn't see it, did she?"

"She did."

"That means she does have dormant reiyoku." Chad spoke his thoughts aloud.

"You don't think she'll have her own powers, do you?" Orihime questioned, worried about her new friend.

"We just have to watch her and make sure she stays away from the hollows." Rukia said, checking her cell phone. Just then, the school bell rang and which signaled for class to begin once again.

Meanwhile

Heiji sat quietly by himself on a plane bound to Beika. What happened to him three days ago was so unreal, monsters and spirits don't exist! That was what he thought until he was attacked by a white masked monster. Thank God he had survived! The best part of this ordeal is that he had killed it by some miracle. As the plane reached its destination, the Osakan got up and left for the first place he knew he would get some privacy.

"I hope that Okiya guy ain't at Kudo's house." Heiji muttered as he made his way to the Kudo household. He searched for the spare house key that Shinichi keeps hidden. He goes inside and finds out that Subaru is not at the house. He goes to the library because it has the largest space in the whole house.

"Okay... Let see if I can do this again..." Heiji grabs his charm and squeezes it in his hand and concentrates. He thinks of his friends, his family and Kazuha. Just then, light green energy flows out of the charm and it expands and take the shape of a katana.

"I got ta start carrin' dis thing all da time so I don' get myself killed." Heiji grinned and took a few practice swings with the energy sword. "Kudo ain't gonna believe dis." Just then, there was a loud roar outside. Heiji's eyes widened at the sound. "Those things are 'ere too! Great, so much fer gettin' away." Heiji readies his energy blade and goes outside to find the monster.

"You got a good smelling soul, human!"

"Eww... Ya don' say tha' ta someone." Heiji muttered and readied him himself for a fight.

"Looks like you won't stand still and let me eat you."

"Not a chance!" Heiji charges at the monster and cuts it with his energy blade. The monster then attacked with his claws but Heiji dodges it with his new found agility.

"That blade isn't the only trick you got." The monster said and attacks him again but fails to hit Heiji. "Die human!" The hollow unleashes a seires series of slashes with its scythe like claw.

"Wait for it... THERE!" Heiji dodges all of the strikes and performs a perfectly timed slash and cuts off one hollow's arms.

"MY ARM!" The hollow roars in pain.

"IT'S OVER!" Heiji grabs the energy blade with both hands and unleashes a vertical slash and cuts the hollow's mask in two and killing the hollow.

"ARRRGHH!" The hollow roared disintegrates. Heiji was exhausted after the fight. The first time when he fought, he passed out, and the second time it felt like he ran a marathon. and The third time felt like he had an hour long kendo workout. Fighting those monsters has been a real workout. Heiji started to notice a change in his strength, speed and stamina. It seemed the more that he fights the stronger he becomes, which wasn't so bad….

There is a problem to fighting those monsters. The main problem was that he has been getting hurt all the time, from burns to scratches to worse. It seems that those monsters have an acidic body, as the first time he fought one, it had grabbed his side and it left a scar on his side. His wounds had caught his mother's, father's and Kazuha's attention. Kazuha and his mom freaked out over his wounds and his father was quiet about it for some reason.

"Well, well… Not bad young man, not bad at all." Someone behind him said. Heiji turns to find... A talking cat.

"What the hell? A talking cat!" Heiji yelled, clutching his charm just in case.

"Not the weirdest thing you've encountered so far, I bet." The cat said. This made Heiji remember the attacks.

"Alright, talking cat or whatever your name is-"

"Shihoin Yoruichi."

"What are those monsters?" Heiji asked.

"They're evil spirits known as hollows. The hollows attack both the living and the dead to feast on their souls."

"Was it a good idea for me to leave Osaka?"

"Yes. The hollows might have attacked you when you least expect it, they even kill their own family and friends." This made Heiji panic.

"Crap! Kazuha is-"

"Very safe at the moment."

"How do you know?" Heiji demanded, worry filling his voice.

"Call her." So he called her and finds out she's okay, but does have a few choice words for him.

"Where are ya, ya ahou?"

"I'm visitin' da kid. I thought tha' I would drop by an' say hello."

"WHAT? You left without me! I wanted ta' see Ran-chan."

"It's okay. Maybe ya can come up 'ere next time right." There was a long pause.

"Heiji, what is really going on? A few days ago you passed out and then you keep getting beaten up somehow… What's going on?"

"Nothin' fer ya ta worry 'bout, it's just a case I'm workin' on. Look I gotta go, see ya."

"Wait-" Heiji hung up and sighs sighed.

"Trouble at home?"

"Yeah, my parents saw my wounds a few days ago an' my mum freaked out about the burn on my side. and The same with Kazuha, but my old man didn' say a thing..." Heiji explained and showed Yoruichi the burn.

"I know someone that can heal you. Come here by five o'clock."

"Okay, so what should I do until then?" Just then, there was another roar.

"Great, these things are gonna run me ragged." Heiji muttered, gripping his charm.

"You'll get used to fighting them soon."

"Why's that?" Heiji asked, confused.

"Because the hollows have deemed Beika their new feeding ground." Yoruichi gravely informed the Osakan.

"As if Kudo didn't have enough problems already." The teen gave a light laugh.

"Don't worry. There is a shinigami here that will take care of the hollows."

"A shinigami?"

"Ah! You're about to meet him." Out of nowhere, a teenager in a black kimono and bright orange hair appeared out of thin air.

'What the- How did he get here so fast?' Heiji thought. The teenager draws drew his sword from his back and brings the blade down, cutting the hollow in two. 'Whoa! He killed it in one blow! This guy must be strong, but I wonder how strong?'

"Well, that takes care of that."

"Not bad. So your you're a shinigami?" Heiji questioned, impressed.

"You can see me?"

"Yep, plain as day. So what's your name?"

"Kurosaki Ichigo."

"Hattori Heiji. Nice ta meet ya." Heiji nodded. "You must be the strongest of your group, right?"

"Well, I am I'm one of the strongest, but I don't bring out my true power unless I need it." Ichigo modestly informed the detective.

'One of the strongest! How much power does he have? and That sword is huge!' Heiji thought.

"Well, I gotta go back to my body. I'll be back in a few seconds." Ichigo disappeared.

"WHOA! How he do that!"

"It's called shunpo." Yoruichi explained. A few moments later Ichigo returned in his human body.

"Alright Hattori, let's talk."

"About what?"

"Like how you have reiatsu." Ichigo said. "It's weak, but it's growing stronger."

"So you can sense it?"

"Yeah, I can sense it. Once you start training more, your power will manifest properly."

"I see... I guess Conan doesn't have any power right." Heiji said.

"Actually, Conan or Shinichi-Kun has a lot of dormant power. All he needs to do is to find a way to unleash his reiatsu." Yoruichi said.

"I see... So when do ya think his power will awaken?"

"Who knows-" Just then Ichigos cell phone goes off.

"Hello?" Ichigo answers the phone.

"Kurosaki! I need help!" A teen said over the phone.

"Who is this?"

"It's Shinichi. Kudo Shinichi!"

"...Wait what!"

"I don't know how this happened. I was attacked by one of those hollows and then I transformed. Look I'll tell you later, I'm on my way to my house." Shinichi hangs up. After a few minutes a young man runs up to them.

"Hey guys, it's me Conan."

"What the- Kudo did you take one of those antidotes?" Heiji asked.

"Hattori! What are you doing here?"

"I thought I would be safe here from those monsters at beika but nope, I just walked into the fire." Hattori said.

"Yeah... Hard to believe that ghost are real." Shinichi said. After that the small group went inside the Kudo house in the living room.

"Alright Kudo-Kun, tell us why your you again."

"Okay, here's what happened."

Flashback

School ended rather well for Conan and his friends. The school was talking about the explosion and what might be causing them. The kids wanted to investigate the cause of the explosions but they were forced away by the police, sometimes it really sucks being a kid.

"Aww man! They won't let us investigate!" Genta complained.

"Yeah! It's not fair!" Ayumi pouted.

"Their's no helping it. I guess we should go home." Ai said. With that the Detective Boys went back to their homes. Conan was walking back to the agency when he felt something in the air, something that was evil and it was coming his way and Every fiber of his being tells him to dodge. Conan dives out of the way and rolls just when the stop he was standing at explodes. The boar like hollow growls at Conan with its red glowing eyes.

"Dammit! How am I suppose to fight something that can kill me in one blow- WHOA!" Conan dodges another attack from the hollow. "I hate is little body, I can't runaway from this hollow with these short legs of my." Conan thought. Just then a surge of power courses throughout Conans body and he became surrounded by a blinding light. When the light fades away Conan felt taller and stronger. He looks at himself and realized that he wasn't a child anymore.

"What the- how did I change!" Shinichi looked at himself. He was wearing a dark blue long sleeve shirt with dark blue pants and a white button down shirt under the blue long sleeve. Shinichi didn't have time to look at himself, he had a bigger problem and the hollow was making the another attack.

"I might be myself, but how I'm suppose to kill it." Shinichi jump over boar hollows attack, but its other arm grabbed him and threw him in the sky, and he crashes on a roof a of a building.

"Dammit- wait... Shouldn't I be dead. The speed that I was going and with the force of the impact I should at least have a few broken bones." Shinchi looks at the clothing he's wearing. The shirt was torn on the back, just then the suit repairs it self in matter of seconds. "What the- the shirt repaired itself but-" Just then the hollow jumps to the roof. "Crap! What do I do? I can't just kill it with my bare hands!"

The hollow then grabbed Shinichi and pulls him to its face and opens its mouth. "I am NOT gonna die like this!" Shinchi gets his arm free and punches it in the eye as hard as he can and the left side of the mask breaks, this made the hollow roar in pain. "Hey, I can do this!" Just then energy collect in his arm and goes into his hand. He thust his fist towards the hollow and unleashes a large blast of energy. The impact of the energy blast kills the hollow and Shinichi is safe.

"How did I do that?" Shinichi sighed.

"Hey! Did you hear that!" Someone said.

"Yeah! It sounded like an explosion!" Another person said.

"Crap! I got to get out of here!" Shinichi said and he made his escape.

End of flashback

"After that I met with Urahara-San and he gave me Ichigos cell number and I came here." Shinichi said.

"I see... It is a rather interesting power, but I think that you should return to your smaller form. Your using up all of your spiritual energy." Yourichi said.

"Did that cat talk?"

"Yes I did, but first you have to change back to your smaller form." Yourichi said.

"How?"

"Concentrate and think of yourself as Conan." With that said Shinichi concentrates and thinks about being smaller. Shinichi body soon becomes surrounded by light and becomes Conan.

"Hey! Your back ta being short." Heiji said. Shinichi looks at himself and he's Conan again and everything is accounted for, good thing he's not "exposed" that would make things awkward. "If you master your transformation power you won't need the antidote."

"You think so?"

"Your power is almost like one of my abilities. So you know, I can transform as well. Behold, my true form." The black cat becomes surrounded by smoke and the cat grows and take the form of a woman. This left Conan and Heiji shell shocked at what they saw, a cat turing into a woman. A woman that happened to be "exposed."

"ARGH! Put some clothes on!" Ichigo yelled."

"Your still acting like that. I thought you've gotten use to it by now." Yourichi said, and looks over to the others. Both young men were red in the face and bleeding from the nose. "I haven't seen that reaction in a long time." Yourichi laughs.

"Can ya get some clothes on, its awkward looking at ya naked." Heiji said as he mended his nose and covered his eyes.

"If you need clothes I'm sure my okaa-san left something here." Conan said as he did the same thing as Heiji did. after getting dressed in a short sleeve shirt and some black pants Yourichi looked at the clock, it was five minutes to five o'clock.

"Conan, it's almost five o'clock. Go to your room and open your window." Yourichi said.

"How did you-"

"Kisuke told me." After that, everyone followed Conan to Shinichis room. Conan then opened the window and waited.

"I wonder why Urahara-San wanted me to do this." Conan remembers his words again. "He reminds me of someone I don't want to talk about." Conan said with half moon eyes. He looks out of the window and notices the nice breeze, the sun was setting and in a hour it will be dark. Just then something moving at high speeds closes the distance and slams on the wall in the room. The ball splatters a red fluid all over the wall and slides down.

"Wh-what the hell!" A message appeared under the red paint.

-Urgent. Cometh to Haido city, warehouse number 15-

Seeing the message made Conan rub his forehead with two fingers and Heiji freaked out.

"This had better come out of my wall..." Conan said.

"What the hell! It like a dying message written in the victims blood!"

"Yeah. This happened to me to, you get use to it. Wait, there's more."

-P.S

If you think that this is some message written in the blood. Then you're a mystery otaku-

"That asshole!" Heiji said clenching his fist.

"I get enough of that from Ran." Conan said.

"Okay you two, don't want to keep him waiting. Let's go!" Yoruichi said. The group of four goes outside and Yoruichi punches Heiji in the gut.

"What the-" Ichigo picked up Conan. "Hey!"

"Don't worry, we're going to get you both there in a flash." Yoruichi picked up the unconscious Heiji. "Ready Ichigo?"

"Yeah."

"Ready for what-" In a blink of an eye the group was gone.

To be continued...

A/N- I got a Beta reader now, which is a big help. She did take her time but balancing school and Fanfic must be tough. I also have the problem with random story ideas popping up in my head. Here one for you Akako fans, what if there was a witch hunter, a legit hardcore witch hunter that's immune to magic, and it's up to Kaito and Saguru to set a side their differences to protect Akako. Just a idea of mine and it's up for grabs. I don't have time to write it.
