The Mystery of the Black Digicores! Taichi Kamiya Turned Back into a Kid?!


This is Earth, our home. Things have been pretty peaceful for the past five years and why shouldn't it? Ok, maybe a few conflicts in the world but that's never stopped us from moving on with our lives. By the way, my name is Tai Kamiya. I'm about to turn thirty in several months. Even at such an age, I still crave for more adventures.

Ever since we defeated the D-Reaper, each of us has managed to move on with each other's lives. But for me, it was just another new beginning. I wanted to go out and get some exercise and what a better way to do than to watch my son, Max, and War Greymon spar in one on one combat.

The skies were as beautiful as ever and the landscape was just as quiet. But that soon was not to be as several scatter shots came showering down from the skies. A armored digimon came soaring over the skies. He was equipped with gauntlets and his aura was glowing like never before.

This is War Greymon, the mega level form of Agumon. He's improved in his fighting abilities five years later. But he's never met a opponent as he's facing right about… now.

Suddenly, a young boy came flying out of nowhere as he started throwing punches at War Greymon. He had red eyes and a mixture of brown/auburn hair. Even an experienced fighter, such as War Greymon, was having a bit of a hard time keeping up with this resilient boy.

And this little guy is my son. His name is Max Tajiri Kamiya. Much like myself, he loves to fight and has a heart of courage. But much like his mother, his love helps guide him through battles.

Max jumps up and stares War Greymon down in mid-air. War Greymon raises his arms and forms an orange sphere. Max was prepared for the digimon's next attack.

"Terra Force!!"

As soon as War Greymon threw the energy ball, Max held out his hands and started to push back on the Terra Force. Tai looked on with encouragement from the top of a nearby rock cliff.

"You can do it, Max! That's the way!"

With a new surge of energy erupting from within, Max screamed out and pushed the energy ball into the air. War Greymon watched as it came hurtling towards him, and quickly materialized out of the way. As soon as he looked down, he saw that Max was nowhere to be found. Just then, he felt a light tap and found Max on top of his head.


"Again?! Man, I'm getting too old for this," muttered the mega digimon.

"Way to go, son! You're getting better at this. I can't believe how much your speed has improved. But you're a Kamiya."

"And a Kamiya never quits."

War Greymon and Max came hovering down to the ground as Tai came walking up towards them. Tai gave Max a light tap on his arm and commended them both for their impressive practice spar.

"Can we do this again tomorrow, dad? I think I'm getting the hang of this!"

"We'll see. You're already the strongest kid in the world. Soon, you might as well become the strongest human in the world by the end of the year."

"Aw, c'mon. You're just saying that dad."

"Hey, I'll tell you what. You're a lot stronger than any digimon were during our old days."

"Really? That's great hearing that from you."

"Yeah. Now what do you say we get back to meeting with the others. My stomach is calling out for a buffet!"

"I'm going to out eat you, dad!"

"Oh yeah! I'd pay to see that any day!"

Just then, a strange hovercraft came landing by. It was metallic blue with a glass covering on the front, but it seemed tinted. Tai and Max couldn't tell who would have been inside.

"I wonder who that is," Max said, "I can't sense anything from it."

"I don't know, but I'm going to check this out," said the Destined leader.

As soon as he was about to approach the hovercraft, a side door opened up and out came a very familiar face. It was none other than Koushiro Izumi, better known as Izzy.

"Izzy?! What are you doing here?"

"Ah! I'm glad I've found you, Tai! Did I just interrupt your training session?"

"No, no. We just finished up and getting ready to head off back home."

"Yeah and I'm going to out eat dad! How you doing, Izzy?" Max said.

"I'm doing just great, Max. Thanks for asking. Tai, there's something you should take a look at. Its something Talley and I have been constructing for nearly a year."


Just as Tai said that, a shorthaired blonde came walking out. She came waving over to Tai and Max.

"Yeah, that's Izzy. He's been dating Talley, one of Yamaki's loyal Wild Bunch crewmembers. They've been working on this project together that might help increase a human's lifespan. Don't ask me how these two did it, but they have used technology to create themselves a real-life fountain of youth. That's a scientist for ya."

"So, show us this gizmo of yours, Izzy," Tai said, "I bet its something worth to look at."

"Oh you'll see."

Izzy went inside of the hovercraft and picks up a device much similar to that of a blender with a lava-lamp on the top. Tai and Max's eyes widened in utter shock as they witnessed the device that Izzy had been working on for a year.

"That… That's the experiment you two have been working on. Man, how hi-tech are you Hypnos geeks," Tai asked.

"What he said," Max replied.

"Well, we managed to put together a real life fountain of youth. We gathered up as much energy electrons from the former Juggernaut program. Then instead of it deleting digital beings in the process, we altered its process and we wanted to see if we could use its energy to lengthen a human's lifespan and help retain their youth."

"Um, he's talking all this techno crap too funny, dad," said Max.

"Speak English, Izzy," replied War Greymon.

"Don't mind him," said a funny voice.

The group turned to see Tentomon walking out of the hovercraft. The insect came flying over the machine.

"It's just as he put it out. Its a real life fountain of youth, with a few modifications to it."

"Right and we collected the last of D-Reaper's energy to help speed up the process," said Talley.

"Now you guys just stay here for a second. Talley, lets go get the manual to this thing," Izzy said.

The two bio-engineers went back into the hovercraft to grab the manual. Tai and Max examined the device with awe looks on their faces.

"So, dad. You think this thing can actually make a person's life longer and keep them from getting old at the same time. I don't buy into any of this."

"Well, let me tell you something about these scientists. Some are just too whacked to even give us any proof over this sort of thing. But I am a little curious."

"I wonder what's keeping them so long," Tentomon said, "I better so see if they misplaced that manual."

But just as Tentomon was about to fly towards the hovercraft, one of his legs accidentally tipped over the device. Tai and Max looked on as it fell to the ground. Izzy came walking out and tried to catch it. But it was all but too late. The device hit the ground and a green blast came shooting out. It nailed a direct hit on Tai and the young man's body was covered in a green column.

"Dad! What's happening to you?!"

"Tai!" War Greymon exclaimed.

"Oh no! I was afraid something like this would happen," Izzy said.

As soon as the light faded away and the green column disappeared, Tai stood with a dumbfounded look on his face. But he was different. He had shrunk down to about the size of a boy and his manly features had all but disappeared.

"Hey, what just happened to… Oh crap!"

Max, Izzy, Talley, Tentomon and War Greymon all gave shocked expressions on their faces. What they were seeing before them was the younger version of Tai. He looked about eleven years old. He was now the age of when he first visited the digital world.

"Tell me that I'm dreaming. Tell me that this just didn't happen."

"Tai. You better take a look at yourself," Izzy said.

Tai walked over towards the hovercraft's front window and looked at his reflection. His first reaction was something that managed to echo throughout the whole island. A horrifying scream was that very sound that shook the island.

"Dad! You're a kid again! Looks like that thing does work! You could be a millionaire, Izzy! Now change him back."

"One problem. I can't. It fell and it's broken."

Tai and Max gasped in shock with Tai falling down unconscious.

"Oh boy. What am I going to tell mom about this? She's going to freak when she finds out," Max said.

"Don't worry. We'll tell her everything and I'm sure she'll understand."

"Believe me. She won't," said Tai, who just reawakened himself.

"Don't worry, dad! At least, you're young again!"

"If only, you're mother could say the same thing."


Shibuya Park

The busy city of Shibuya looked very beautiful from a further location, but it was simply another hellhole once approached. Traffic was just as horrible on the usual working days. However, it wasn't as bad as Tokyo or New York City. Those are even worse.

Luckily there were a few who took advantage of this hectic day and decided to take a nice stroll through the park. There were many couples finding refuge to get away from all of those busy schedules. The same couldn't be said for a certain pre-teen boy and a girlfriend of his.

The boy was wearing a green cap, which of course was backwards. There was a pair of goggles on that cap. His shirt is yellow-orange with an emblem logo on the front. Around his shirt were a red vest and a pair of gloves on his hands. His pants were brown cargos and his shoes were a mix of red and orange with white laces in between them.

The girl was wearing a light lavender hat with blue streaks at the bottom. Her shirt was striped with a mix of blue and white. Her vest and shirt were the same color as her hat. Her shoes were a mix of light lavender, blue and white. Her hair is blonde and was coming straight down past her shoulders. Her green emerald eyes were locked towards the heavens.

"Isn't it just beautiful, Takuya?"

"Sure is if you like red and purple. The sun is about to set."

"What? You want to go home already?"

"No, it's not that."


"Zoe. I need to ask you something."

"What is it, Takuya?"

"Do you ever miss being a digimon?"

"Kind of, why do you ask?"

"No reason. It's been almost a year since we've been to the Digital World and saved it from Lucemon."

"Yeah, but look on the bright side, at least we stopped a maniac from destroying our home."

"Yeah, but who would have forgotten what happened five years ago."

"Our planet was destroyed and we were all revived back. It was as if a miracle had just taken place. I'm grateful. Now I was able to fully mature into the cute blonde girl you see today."

"You sure love being so full of yourself, do ya?"

"Not entirely true. I'm just proud of who I've become. Remember, I was the legendary of mind. Thank you, very much!"

"Yeah? Well, I was the warrior of flame."

"Big difference. So, what do you think about me?"


"Yeah. You can be honest. I swear I won't get mad."

"Really? You're not too sensitive about these things? I've never really been on a date until a few months ago."

"I wouldn't really call it a date, just a get together."

"Same thing."

"Whatever. So, what do you think about me?"

"Well… I…"


Takuya looked deeply into Zoe's eyes and was slightly blushing from her cute face. The boy gulps and felt rather edgy. A girl like Zoe before has never approached him. Clouds began to cover his mind and he couldn't think of anything that would sound pleasing to a girl.

"What am I suppose to tell her? It's too soon. She knows that. I know that."

"I'm waiting, Takuya Kanbara."



"I think you're a really cute girl with a good sense of humor and pretty eyes. There…"

"Is that all?"

"Well, what am I supposed to say? You want me to get into further detail?"

"No, you don't have to if you don't want to. I won't hold anything against you. I completely understand."

"What was I supposed to say anyway? I've been in tighter spots, but this one's a toughie."

Unfortunately, the sun was ready to set and dusk would soon break out. Curfew for Takuya and Zoe was about to begin within another hour or so. They made a good decision to leave the park a little early to go about the market squares to pass the time.

Takuya and Zoe were walking alongside each other, but were sort of turned away. They didn't even make eye contact with one another.

"Maybe it was a little too soon," Zoe thought.

"Man, why am I so edgy with Zoe? I can't even express my feelings for her. No, because I would sound like some stupid, hopeless romantic."

Unknown to Takuya, his cell phone was emitting a faint red aura and an incoming message was coming from an unknown source. The message read You must return to the Digital World. It's urgent. Takuya took notice of his cell phone and pulls it out.

"Hey, Zoe!"

"What is it?"

"I think you should check this out."

The goggle boy handed the blonde his cell phone and she gasped slightly.

"You don't mean?"

"It looks like it, Zoe. We were needed back again. I knew it was too good to be true."


Odaiba. Taichi & Sora Kamiya Residence


The entire house shook under its core as Sora's eyes widened. She looked down at her husband, who was now twice as younger than she was. Max stood next to him. TK and Kari had just arrived as they peered down at the youthful Tai. Their kids, Tike and Kara, were over in the other room playing video games and cursing as usual.

"Shit! I can't believe you beat me again!" Tike exclaimed.

"It's not my fault I'm that damn good," said Kara. "Want me to kick your ass again?"

"This time it's going to be you that gets their ass kicked!"

"I've really got to do something about those potty mouths," TK thought.

"Look on the bright side, mom. At least, you have two kids."

"Oh no! What are we going to do when the whole Digi-Destined gets here?! Today is the reunion dinner!"

"It's today?!" Tai, Max and Agumon asked in unison.

"You three forgot? Oh, what am I going to do," Sora said.

"Don't worry, Sora. Since it was an accident, I'm pretty sure Izzy will tell everybody about it," Biyomon said.

"You're right. I was just overreacting just a bit there. Sorry. Ok, this dinner is going to still going to take place. Now, you three better be on your best behavior. You know what. I might actually like this, Tai. But, at the same time, I won't."

"Don't worry, Sora. At least the other guys will get jealous when they get a look at the new and improved me!"

Keke is coming to the dinner! I can't wait to see her!"

"So, tell me, Max," Tai said nudging his son's shoulder. "You got a crush on her?"

"Huh? What are you talking about?"

"Oh don't play dumb, Romeo. You go all goo-goo eye over that girl. Just say that you like her."

"Ok! I like her! And maybe I do go goo-goo eyed for her!"

"Now, see? You didn't have to hide it. But remember, in order to get the lady to like ya, you have to stay on her good side and let her know how you feel about her."

"Dad?! Shut up! You don't think I'm going to do that?!"

"Hehe. I don't know. By the time this dinner is over, you'll be Max 'The Playa' Kamiya."

"Dad! I'm only five and a half!"

"And growing up quickly. C'mon you gotta take a chance on her."

"Well, ok. I'll give a shot! I'm The Playa!"

"That's my boy! So, what do you think, Sora?"

"Tai, if he ends up like you, I don't know what I'm going to do with myself."

"Then again, we could always use the digicores to restore you're age, Tai" Kari said. "You know you probably wanted it this way. You are going to turn thirty within the next few months."

"Well, I really did like being an adult, but I get a kick for being a kid again. I can spend more time with Max!"

"Yeah, it's be nice if we were kids again, Kari," TK said.

"No kidding. That would be so awesome."

"Ok, so we'll go to the Digital World and borrow Azulongmon's digicores," Tai said. "It's a piece of cake."

"I'm afraid not, Tai."

Everyone around the room were stunned by the sudden voice and looked around to find the source of that loud voice. Tai easily recognized the voice from none other than X himself.

"Hey, X! How's everything been?"

"Nothing much. We're just chilling out and watching you're world. Everything's been cool, but I did notice you had a 'little' accident."

"Yeah, but we're planning to go to the Digital World to borrow the digicores."

"I'm afraid I have some bad news to report. As of today, Azulongmon has informed me that the digicores have become inactivate. Every thousands of millennia, these digicores are said to lose its luster unless they are recharged."

"So, we can't use the digicores? That really bites ass," Tai said.

"How long does this recharge period take?"

"Well, TK. I was told they would recharge for one full earth year."

"What?! I have a whole year to remain as a kid? Well, at least I have more time to spend with Max. That means no more work! Whoo hoo!"

"But I have a solution to this problem," another voice responds.

"Shintomon! It's also good to hear from you," Agumon said. "How's the planet doing?"

"Well, everything is still pretty much finished. You guys pretty much trashed up our planet when you battled the D-Reaper. Now we realize the problem of you're situation and there is a way to restore you're age Tai."

"Really? How?!"

"There are another pair of digicores and they're found within the Western sector of the Digital Universe. We've found the pinpoint location and this is the sector we thought was destroyed altogether. There is one planet left in that sector and it's been reformatted since a year ago."

"So, there's only one planet in that sector?" asked Kari. "Wait, I remember you said that one sector was completely wiped out and this one's it?"

"Yes, Hikari. We were very fortunate to know that a planet remained. We know for a fact that the black digicores are there. You guys are to meet me back on my planet, but I'll come to you in a short while. Now listen, this is very important issue and it concerns these digicores. They are called the Black Digicores. They are to be collected at once and here's the kick. If you use up a wish from these cores, they must be returned to that exact same planet before the year expires. If they are not returned to the planet they were used, then that planet will go off with a bang and I mean LITERALLY go boom."

"Whoa! That's not good," said TK. "Well, Tai. We've got our hands full."

"Don't worry. We'll get these digicores," Max replied. "You can count on it."

"Thanks, Max. All right, Shintomon. X. When shall we begin?"

"We'll let you know on further detail. Until then, enjoy a relapse of childhood,"X replied.

"Well, gee, thanks a lot. Well, guys. We're dealing with another new adventure."

"I'm all up for it, dad!"

"The sooner the better, guys. Then again, I can relive my childhood memories and spend time with Max. Another adventure! Wow! I can't wait to tell Takato about this. He'll flip!"


Shibuya Train Station

Takuya and Zoe were replying to Ophanimon's messages through the cell phone. She had already informed them on the same Black Digicores.

"So, we're to find these Black Digicores and bring them to you?"

"Yes, Lucemon had scattered them many, many millennia ago in hopes of ridding anyone's chances of using them to destroy him. Now, with Lucemon gone forever, we'll need the Black Digicores. Unfortunately, higher beings like ourselves can't touch them or we'll die. They are not meant to be touched by being such us ourselves. We would really appreciate it, legendary warriors. I shall inform the other children about this. We'll be looking forward to seeing you once again. Fare thee well, children."

Takuya looks over to Zoe and nods his head. The girl replied with a smile.

"You know what this means do ya?" Zoe said.

"Yep. It's back to the Digital World we go!

With Tai reverted into child form, he and his friends have been informed about the Black Digicores. They are to enter the Western Sector and retrieve them. However, they'll more likely have a little competition. Ophanimon has now informed Takuya and Zoe of the situation concerning the Black Digicores. Just whom are the cores really meant for? Tai's unfortunate regression or the holy angel's wishes?

[Digimon Frontier ending theme "Innocent -Mujaki na Mama de-"]


Tai: Hiya! It's me, Tai! Shintomon has summoned myself, Max, Keke, Takato, Rika, Kari and Davis to the Central Planet. Looks like we're hitching a ride on a spaceship! Man, I'm looking forward to this trip!

Takato: Hey, does this ship come with a portable refrigerator?

Tai: You'll get to see some familiar faces along the way and several new faces. Just who are these kids with Takuya and what purpose do they serve in this Digital World?

Takuya: It's back to the Digital World, guys! Let's move out!

Kari: Next time on Digimon Fusion Frontier, episode two!

Blast Off to the Western Sector! Introducing the Frontier Digi-Destined!

Max: Don't you miss it!


SSJ4T: That was a short chapter but that's a little prologue of what to expect for the next chapter. The season will get better as the chapters pass through. Originally, I was going to have Dimitri go with them, but I chose Keke in order to keep max company. Besides, he'd feel lonely without her. Oh and don't expect any fusion warriors for a little while either. I want to try to keep the power levels balanced between our groups.

Coral: I can't wait until Tai's group eventually meets with the Frontier gang.

SSJ4T: It'll be interesting to see which side do the Black Digicores really belong to. We might see a little quarrel over the Black Digicore possession. Anyway, be sure to also check out the second chapter of my YuGiOh/Digimon fic. Until then, we're out of time!

Coral: So you guys peace out and take it easy! Ciao!
