A/N: After such critiques from, "Heiji and KID VS Black Star", I decided to do a remake and delete the original because it has been hated. Well, anyway, let's just say that, I'll try doing the 'improved' version of the fanfic. Whether if it improved or not, I hope you will like it.

Heiji and KID VS Black Star: The Remake

Chapter 1: The Preparation

It was another fine Saturday afternoon in Beika. It was 11: 30 am, and nothing much has happened recently. People were the same as usual, wondering along the streets going somewhere. Other people just stayed in their homes because they were bored. And one of those 'other people' was seven-year-old Conan Edogawa.

He was lying on a couch in the living room of the Mouri Detective Agency. Apparently, there was nothing to do. Detective Kogorou Mouri went somewhere, saying that he will be 'investigating a case' while Ran Mouri was at the kitchen, preparing for lunch. The boy didn't plan to eat lunch, anyway. He isn't starving for food, he is starving for cases, even if it is only a simple case. Until suddenly, the door creaked. Conan stood up and looked at the door's direction. Much to his surprise, there stood a 17-year-old tanned teenager. He was wearing a gakuran and he brought a blue shoulder bag with him. That teenager was no other than Conan's best friend and rival: Heiji Hattori.

"Oi, Hattori!" the boy exclaimed in an annoyed voice. "What are you doing here?"

"Yo, Kudo!" the teenager greeted as he putted his shoulder bag on the table and sat beside the boy. "I've came here 'cause there's somethin' interestin' that I am goin' to tell ye."

The boy raised and eyebrow, "Interesting?"

Heiji nodded, "But, before I start discussin' about that, do ye know Kaito KID?"

Conan became surprised as he heard the name, 'Kaito KID'. Yes, that is name of the famous phantom thief that Conan wanted to catch.

"'K-Kaito KID'!?" Conan exclaimed in surprise. "Of course, I know him! Since I've been going to his heists so that I can catch him, I know him very well."

And with that thought, something flashed into Conan's mind that made him surprised. "Don't tell me that-!"

"Yeah, ye got it, Kudo," Heiji said. "He sent a notice to the Osaka Police Department. Accordin' to the notice, he is after the jewel called, 'Sapphire's Tears'."

Conan became excited as he heard the information. "Heh? So, he's after another jewel again, huh?", he thought. He then, looked at Heiji with a smirk in his face. "What did he say in the notice?"

The teenager noticed the boy's expression. He knew that from that boy's expression, the boy wanted a very interesting case for some time and now, he found one. He smiled and said, "I think it went something like this:
"Tonight, when the full moon appears, all the petals will fall.
"And, by that time, I already have, the tears of the sapphire.
"I wish that that person will come here to catch me but, I don't think he'll be alone. If that person has a companion, I will gladly meet them face-to-face.
-Kaito KID"

Silence occurred after Heiji memorized the phantom thief's notice. He looked at the boys who was thinking deeply after he memorized the notice.

"What do ye say, Kudo?" he said in a cheerful-like voice. "Isn't it interestin'?"

"Yeah," the boy replied with a smirk in his face. "I'm turned on."

"Actually, I also have another reason for comin' here all the way from Osaka." the teenager said as he rested his back on the backrest of the couch and crossed his arms. The boy raised an eyebrow from the high school detective's statement.

"Eh?" Conan muttered.

Heiji looked at ceiling with a confused face. "It was the last verse, Kudo."

"What about it?"

"It triggered me."

"Huh? What do you mean?"

"It's just I don't get what it meant by, 'If that person has a companion, I will gladly meet them face-to-face.'."

Conan smiled at his best friend's statement. "You're thinking too much, Hattori," he said. "He is referring to me, as 'that person' and you, as the 'companion'."

Heiji raised an eyebrow with confusion in his eyes. "How come?"

"I was famous here in Tokyo for being the 'little detective' who tries to capture KID in his heists and the one who protects the jewels from getting stolen," Conan explained. "And, since the next target is in Osaka, I guess that that thief knows you, being the 'Detective of the West'."

"I see..." Heiji muttered. "Then, could that possible mean-!?"

"Yeah, KID knew that we will be guarding his next target, thus, the last verse of the notice."

"As expected from Kudo! Ye really are famous for being the 'little detective' here in Tokyo!"

As Heiji said so, he tousled the boy's hair, which annoyed Conan.

"Pssh! Shut up, Hattori," Conan said in an annoyed voice as he fixed his hair. "Anyway, the second verse was also easy but, we need to solve the meaning of the first verse. Say, Hattori, what time would the full moon appear?"

"Hmm?" Heiji muttered as he did a thinking face. "If I am correct, the exact time was on 7:48 pm."

Suddenly, something flashed in Heiji's mind which surprised him and made him stood up. "Does that mean-!?" he said as he looked at the boy.

"Yeah, that's right." Conan said with a smirk in his face. "That's the time KID will appear and steal the jewel. I just hope that the police, especially Inspector Nakamori, will come to Osaka."

Finally, Heiji sat back on the couch and rested his back at the backrest of the couch. "Ah~! And with that, everything is now clear. As expected from the two of us. Our minds always sync with each other."

"Now that I think about it, what will be our next move, Hattori?" Conan asked, still in his somewhat deep adult-like voice.

"Hmm? Of course! We're gonna go to Osaka and check the jewel!" Heiji exclaimed as he clenched his fist.

"Eh!?" the boy exclaimed, now in his child-like voice. "But-!"

"Don't worry about it, Kudo!" Heiji winked at the boy. "I'm gonna tell Neechan about it! Just wait here."

And with that, Heiji went to the kitchen and leaned against the wall, with Ran not facing him because she was busy cooking.

"Say, Neechan," Heiji began.

Ran heard Heiji's voice and turned around. "Ah! So, it really was you, Hattori-kun!"

Heiji raised an eyebrow from the brunette's statement. "Hmm? What do ye mean?"

"Well you see, I kept hearing some chatting going on at the living room. I thought it was some client talking to Conan-kun but, when I heard a lad spoke in Kansai-ben, I thought it was you."

"Oh...Is that so?" Heiji muttered as he scratched his head. "Well, anyway, the thing is, can I bring the brat with me to Osaka?"

"Eh? Why is that? Lunch is almost ready!"

"Well, it's just that I haven't talk to this brat for a few weeks! Also, no such case has been goin' on lately here in Tokyo. So, I decided to bring 'im with me to Osaka."

"What about his lunch?"

"Don't worry about it, Neechan! I'm gonna treat him some! Trust me!"

"W-Well, OK. But, you two better be careful. If something happens to Conan-kun, call me, OK?"

"Yeah, sure! Don't worry! Since he's with his master, I won't let my student get harmed!"

"Very well then, Hattori-kun. I'm counting on you. How long will he stay there, by the way?"

"I guess by tomorrow? I'm not sure."

"OK, then. Just make sure you take good care to Conan-kun. If you arrived at Osaka, please say hi to Kazuha for me."

"Sure! I'll do that! Well then, I'll be off with the brat now."

"OK. Take care."

Heiji went back to the living to tell the good news to the boy. Conan looked somewhat annoyed, probably because he thought that Heiji used some sort of excuse.

"So, what did she say?" Conan asked.

"It's a yes from her! She said that I should take care of ye. And since it's almost lunch time, I'm gonna treat ya some okonomiyaki once we arrive there.

"Heheh...Oh, really?" the boy thought annoyingly with an annoyed smile across his face.

"Well then, let's go!" Heiji said as he grabbed his shoulder bag.

"Fine." Conan said with a sigh. "Ran-neechan, we'll be leaving!"

"OK, be careful!" Ran replied from the kitchen. "Geez, those two!" she thought. "Will they really be alright?"

Meanwhile, outside the detective agency, the two rode on a taxi on their way to the train station. Once they arrived at the train station, Heiji got tickets for the two of them and went for the train to Osaka. While they were still on the train, on their way to Osaka, those two kept chatting about their lives, the on-going case and their plans.

Finally, after a long trip from Tokyo to Osaka, the two young detectives arrived at their destination. While walking on their way outside the station, Conan finally noticed something that bothered him for quite a long time on their way to Osaka.

"By the way, Hattori," Conan said. "Why are you wearing your school gakuran?"

"Oh, you mean this?" Heiji said cheerfully as he looked at his outfit. "It's just that I really want to meet you that I hurried and forgot to change clothes."

"Oi, oi." the boy simply muttered.

"Oh yeah! I almost forgot! I gotta treat ye some lunch today!" Heiji exclaimed. "Ye're lucky today, Kudo, because ye're goin' to taste the best okonimyaki every in Japan!"

"Oi, quiet down, you idiot! We're in public!" Conan warned Heiji with a quiet deep voice.

"It can't be helped, Kudo," the teenager snapped back with an annoyed face. He then, looked excited. "Anyway, let's get goin'! To the okonomiyaki restaurant!"

Conan just sighed annoyingly and facepalmed while the crowd giggled silently in Heiji's behavior. "You gotta be kidding me!" Conan thought annoyingly.

And so, the two headed off to the okonomiyaki restaurant which Hattori claimed to be the best restaurant ever in Osaka. They hailed a cab and it took 15 minutes for them to reach the said restaurant. Finally, they arrived. As they entered the restaurant, the owner greeted Heiji happily.

"Irasshai! Ah, Heiji-kun!" the owner greeted happily. "What are ye doin' here? And who's that kid?"

"Ah! This little kid?" Heiji said as he lifted Conan and pointed at him. "He's my lil' assitant."

"Woah! So, ye got yerself an assistant! And, a very young boy!"

"I know. But, he has a mind of a detective. Right, K-K-Conan-kun?"

"Oi, oi." Conan simply thought to himself as he smiled annoyingly.

"Anyway, Occhan," Heiji said as he faced the owner. "I'm plannin' to have my lunch here."

"Oh! OK, then. Take yer seats!"

Heiji and Conan sat beside each other as Heiji told their order, "Two okonomiyaki. One medium-sized for the kid and one big-sized for me!"

"Right away, Heiji-kun!" the owner replied as he started cooking some okonomiyaki for the two. While cooking, the two have a light conversation.

"The owner seems to be nice," Conan commented. "It seems that you two are so close with each other."

"Of course!" Heiji said happily as he grinned at the boy. "That's because I am his regular customer! Oh, and also Kazuha!"

"Eh...?" Conan simply muttered as he watched the owner cooking the okonimyaki. After a few minutes, it was ready to eat.

"Here! One medium-sized for the kid and one big-sized for Heiji-kun," the owner said as he putted two plates of okonomiyaki on the table.

"Woah! It looks delicious! Thanks, Ossan!" Heiji thanked the owner happily.

"Enjoy yourselves!" the owner finally said as he left the two boys eating their lunch.

When Conan took his first bite, he was wide-eyed with a wide smile in his face. "Wow! The okonomiyaki here is more delicious than in Tokyo!"

"See? I told ye so!" Heiji said happily. "After this, we're off to Mr. Hiroshi Maru's hotel!"

"'Hiroshi Maru? Who is that?"

"Oh, I forgot to tell ye about it! He's the owner of the targeted jewel, 'Sapphire's Tears'."

"Oh...And, you know his address?"

"Of course! Because I want ta solve this case with ya!"

Conan was surprised from Heiji's statement. It was the first time in his life Heiji told something like that to Conan. "Hattori..." he simply thought.

"Oi! Stop day-dreamin' and finish eatin'! I swear, I should have order a small-sized okonomiyaki for ye instead," Heiji said with a somewhat annoyed expression.

"Eh? Ah, sure," Conan muttered.

Finally, the two finished eating their lunch. When they were about to leave the restaurant, the owner said, "Thanks for comin'!"

Heiji waved back, "Yeah, Ossan!" He then, looked at the boy, "Let's get goin', Kudo!"

"Yeah, sure." Conan said as he smirked once again.

And so, the duo headed-off to their next destination, which is...Heiji's house?

"Wait! Why are we going to go to your house!?" Conan exclaimed in surprise.

"Aho! (Fool!) I know a shortcut to the hotel. Because of that, we're gonna use my motorcycle!"

"Are you serious!? You're only wasting money!"

"Not for now!"

Conan, once again, facepalmed at Heiji's statement. When they arrived at Heiji's house, Heiji quickly got his motorcycle at the garage. When Heiji arrived outside the house, he tossed a helmet to the boy.

"Hop on, Kudo!" he said as he quickly grabbed the boy's arm and they went on their way to the hotel. And as Heiji said, he did knew a shortcut to the hotel. They passed some alleyways on their trip. Then, there was a metal fence on the way.

"Hold on tight, Kudo!" Heiji exclaimed as he started to speed up. Then, they jumped on the metal fence and went straight to the main road.

"Jeez, Hattori! Is this how you drive whenever you have someone with you!?" Conan exclaimed.

"Of course! Even Kazuha doesn't actually mind!" Heiji replied back.

Finally, they arrived at Mr. Hiroshi Maru's hotel, which is Koheiki Hotel. Heiji parked at parking lot beside the building. He and Conan removed their helmets and checked the building. It was a very tall building, probably 20-30 floors. As they entered the hotel, they searched for Mr. Maru's room number which was, Room 141.

"I think it was around this floor." Heiji said as he and Conan wondered around the 20th floor. Finally, they found the room. Much to their surprise, they noticed some police gathered around the room. They saw Inspector Nakamori, a man in his mid-thirties, and a teenager who is around the same age as Heiji. As the two approached the room, everyone heard their footsteps and looked at their direction.

"Ah! He is the one! That kid! He will keep the jewel!" the man in his mid-thirties exclaimed as he saw Conan. The man was wearing a beige coat over a pale green polo shirt, beige pants, and black shoes. He has brown hair, brown eyes, peach skin and wears glasses. He is normally build, a little stout, quite tall and has shaved beard.

"Eh!?" Inspector Nakamori muttered as he looked around and found Conan. "Huh!? C-Conan-kun!? What are you doing here!?"

"I heard from Heiji-niichan that KID sent another notice here in Osaka!" Conan said in his childish voice.

"'Heiji-niichan'?" Inspector Nakamori raised an eyebrow as he looked at Heiji. "Oh...You must be Heiji Hattori, the son of Heizou Hattori, I believe."

"Ah, yeah," Heiji replied.

"Oh? So, that's the famous Detective of the West," a voice rang out. It was the teenager that Heiji and Conan saw. He was wearing a black blazer over a black turtleneck, black pants and black shoes. He has short straight black hair with one side of hair dyed with yellow. He has emerald eyes and a peach skin. He is normally build, quite thin, and is as tall as Heiji. Because of the sudden appearance of the young lad, Conan and Heiji's mind synced.

"Who the hell-", Conan first thought. "-is that guy?", Heiji thought then.

Then, their thoughts interrupted when they heard Inspector Nakamori cleared his throat.

"Well then, let me introduce to you to these people," Inspector Nakamori said. "This is Mr. Hiroshi Maru, the owner of the KID's targeted jewel, the 'Sapphire's Tears'."

"Pleasure to meet the two of ye," the man greeted the two.

"While this young gentleman is Kuro Maborshi," Inspector Nakamori said as he pointed at the teenager. "He will be the one who will capture KID."

The statement made the two detectives surprised. "Eh!?" they exclaimed.

"W-W-Wait a sec, Kebu-han!" Heiji exclaimed. "I don't understand! I thought, I'll be catchin' that white thief with this kid!"

"Just, calm down," Inspector Nakamori told Heiji. "This young man, actually knows black magic and sorcery."

"'Black magic'?" Conan thought surprisingly.

"'Sorcery'?",Heiji muttered. "Ya mean that forbidden magic that witches and wizards use, right?"

"Correct," the young lad replied. "I learned some of them. My father taught me. He was a sorcerer, after all."

"Ye've gotta be kiddin' me! There are no such things as black magic and sorcery right now in the present!" Heiji thought to himself as he turned to Conan. He sat on his feet and whispered at the boy's ear. "Oi, Kudo!"

"Yeah, I know that already," Conan said in his deep adult-like voice. "I'm having a bad feeling about this...But, yet, this will be interesting, right?"

"Kudo..." Heiji thought to himself as he saw the boy's confident face. The boy had a smirk across his face once again. Heiji simply smiled. "Yeah, ye bet! This will be a battle between darkness and light..."
