Title: Opposites attract

Summary: Tsuna and her friends had saved the world from Byakuran and are finally home. With the danger now gone though, she had to deal with the fact that in that future she had become a mafia boss and Reborn is as unrelenting as ever with taking the choice from her and insisting she becomes the boss. But! She didn't want to be one! It was then that the brunette received a curious message on her phone which will, unknowingly to her, lead her to the chance to get to know herself.

Pairing: fem!Tsuna x Koji

A/N: Age: Tsuna 14 – Takuya 14 – Koji 14 – Zoe 14 – JP 15 – Tommy 12 – Kouichi 14

Disclaimer: Digimon Frontier and KHR don't belong to me, but the plot does.

…do you want to start or not start? Yes/No…

"Yes." …What am I doing?! This totally screams suspicious! "Tsunayoshi, the game which will decide your destiny has begun. Take the train from Shiogaoka to Shibuya at 17.45."

Tsuna stared at her phone display with wide eyes. How does it know my name? She felt uneasy and decided to just ignore the message and forget she ever received one…and couldn't: The brunette felt her intuition spike and urge her to do as is written, that it was important for her to do so. Damnthe Vongola Hyper Intuition! "Why me?" she whined, though no one could hear her as the street she currently was in was empty. The girl was alone, a rare occurrence with the kind of friends she had. Her shoulders slumped in defeat she checked the time and stilled. "Shit!"

Giving no thought to the fact that she had cursed, the brunette wasted no time in slipping her gloves on and entered HDWM. Once she did that, she immediately did a powerful jump and used her flames to fly towards her destination as fast as she could. It was currently 17.00 o clock hence the rush. Tsuna only had 45 minutes to board the train which would have been enough time for anyone else but her. Whythe hell isit Tokyo?! I'm not in Tokyo, I live in Namimori! How do they expect one to get from Namimori to Tokyo in 45 minutes?! The only reason I could possibly make it is because of my flames! As the mafia boss-to-be flew at top speed and mentally ranted to herself she completely forgot the little but important fact that no one knew about her departure and thus would think her missing or kidnapped.
.

.
When she finally arrived over Tokyo Tsuna searched for an empty alley way near Shiogaoka where she could land unnoticed and then came out of her HDWM. Pocketing her gloves she hurriedly ran towards the train station but halted at the ticket machines. Now that she was there, the brunette remembered that because of her unexpected leave she didn't take any money with her. The girl sank to her knees in failure and cast a contemplative glance through her bangs at the gates, playing with the thought to just jump over them but then shook her head. She couldn't do that. Besides with her clumsy nature the personnel would catch her before she even made it. Tsuna didn't know what to do, though maybe the situation wasn't as bad as it seemed since she didn't even want to go in the first place. With that thought she stood up, set to go back home and may have even succeeded if it weren't for the fact that her foot slipped (she didn't even know how, since it was not like the floor was wet thus slippery) and she collided with the ticket machine she had sat next to. In response the brunette suddenly heard noise and looked up to see the machine conveniently spit a ticket out. That can't possibly be coincidence. The young Decima skeptically eyed the ticket, hesitating to take it. Although all indecision left her when she saw the time and instead of thinking, the girl just did. Grabbing the ticket she hurriedly passed the gate and entered the train she was instructed to take. Once inside she took a seat and sighed in relief. However any relief left her as she realized what she had just done and sank her head. Why did I do that? Aahh! Stupid Hyper Intuition! After she finally lifted her head she unconsciously searched her surroundings for any threats but stopped once she realized what she was doing. Nooo, she whined mentally, I said I didn't want to be a mafia boss! I don't even want to think about what Reborn would do if he ever finds out that his lessons stuck with me. Tsuna then heard her phone beep only to discover another instruction:

"Change-over in Shibuya and take the train at 18.00 o clock."

Since the brunette couldn't see the time on her display because of the message she had to ask the person next to her only to freeze in shock at the answer. She only had six minutes left until the stated time!
.

Tsuna was already standing by the door when the train arrived in Shibuya and exited as soon as the door slid open. Searching the signs for the right way the girl finally spotted the elevator she had to take only to panic as they began to shut. However her panic didn't last long as quickly determination settled in with her eyes narrowed in concentration and then she started running with all that she had. Out of the corner of her eye the brunette saw she wasn't the only one desperate to make it to the elevator. Her intuition notified her that the boy running slightly behind her was somehow involved with whatever was awaiting her and thus important. Because of that she held her hand out between the closing doors for him to take. She saw his face show surprise at her action but took her hand nonetheless and then she pulled with all the strength she could muster while at the same time he leaped towards her. He was hardly inside when the doors finally closed behind him, though due to the combined strength of her pull and his jump the momentum was too great for him to stop and the boy crashed with the girl who lost her footing so her back painfully collided with the wall. Tightly pressing her eyes shut, Tsuna bit back a scream. She didn't want the boy to worry or feel guilty for something that was the result from her own idea and since she was used to stronger pain. After the two of them stood back up and the boy turned to her person, the pain was already hidden.

The boy before her had lightly tanned skin, brown eyes and hair over which he wore a light khaki colored cap with a pair of goggles. He wore a yellow shirt with a black symbol printed on the chest area underneath a red jacket, khaki Bermuda and orange-red sneakers with white socks and soles. "Are you okay? Sorry for uh crashing into you and thanks for the help," he said with a sheepish smile while scratching the back of his head with a gloved hand. "Yeah I'm fine." Tsuna smiled reassuringly, not showing any indicator to belie that statement. "You're welcome and there's nothing for you to be sorry for, it was my idea after all."

"Did you also get some weird message on your phone?"

Before the brunette could answer someone else did… well kind of. The only response was an annoyed "urgh" as the person turned his back to them. Because she hadn't noticed another person present, the girl startled slightly. The other boy seemed to be the same age as the goggle-head and herself. A blue-gray camouflage bandana covered black hair pulled in a low ponytail with two strands framing his face. He wore gray ankle length pants, blue socks, white-blue sneakers and a yellow T-shirt underneath a blue jacket. Also the fleeting view of his front was enough for her to know that his eyes were the color of dark blue.

"Hey, I asked you something!" Turning her attention back to the cap wearing brunet she answered his question with a positive one, not wanting them to fight. Suddenly the elevator sped up and beeped at supposedly passed floors that weren't registered. In response Tsuna tensed in preparation for whatever was to come. Could this be a trap? No, my intuition would have warned me. The girl shot a quick glance towards the goggle-head when he exclaimed: "Oh man! How far downwards does it get?"

.

"Uh! That sure was no soft landing…" the brunet trailed off when the doors slid open to reveal another station with no ceiling, a round platform and several different colored and shaped trains with many more children already there. "That is mind-blowing."

"Yeah," agreed Tsuna quietly. "Do you think they all got the same message?" The brunette asked but received no response. She lifted her phone and looked at it when she heard a feminine voice coming from it. "You have to make the choice now. Do want to go on or rather go back home?" Looking up she saw the boy in blue clothing already heading towards a train while boy-in-red seemed to be slightly confused. Feeling her intuition push her towards an earth colored train she turned to the person still next to her. "We should go too, it's almost time." Together they started towards the train she earlier had felt a push to. When they were almost there, the doors one after another closed and the all trains started moving. "Wait!"

The two of us were running now; this time Tsuna was behind the boy. She heard him curse. Then he succeeded in grabbing the rail and with a jump he was on board. When the brunette shot a quick glance forwards, her eyes widened. The platform ended in a few meters which meant she had to hurry or she wouldn't make it. "Hey!"

The boss-to-be turned to the goggle-headed boy was surprised to find him grinning at her, one hand holding the rail while the other was extended to her. Grinning in return she put more effort in her sprint and grabbed his hand. When she reached the finishing point of the platform she leapt as hard as she could. The girl was terrified when it seemed she wouldn't make it but then she felt him pull and the next moment Tsuna found herself safe in the boy's hold around her. Once she regained her breathing she couldn't stop herself from laughing in relief and heard him chuckling with her. He let go off her and smiled.

"That was close."

"Yeah, I was scared I wouldn't make it. Heck, I wouldn't have, if you hadn't pulled me in the last second. That was scary, thanks." Tsuna knew her voice was slightly shaking and was glad he didn't comment on it and just lead her inside. The first wagon they went in was empty, the next one wasn't. There were 3 people each sitting on a bench for themselves. One was a plump boy with short auburn hair, wearing a blue jumpsuit with yellow accents eating a chocolate bar. Another boy, this one short and probably younger than them had short brown hair which was covered with an orange balloon-like hat and had his head lowered dejectedly. He wore a white T-shirt with yellow pants. The last person was a girl like herself. She had blonde straight hair which fell to mid-back and green eyes. She wore a pink beanie, a pink skirt with a matching vest and underneath a white and blue striped shirt that went to her elbows and showed her belly. Only the blonde and the auburn-haired one turned to the two of them when they entered the wagon.

The goggle-head next to her showed them his phone as he asked if they also received the message to head to that station. After he spoke his question out loud, the auburn-haired boy turned away from them while the blond answered that she did receive a message on her own phone. The blonde looked towards the other occupants in the wagon and then back to them. "So with the two of you we are a group of five."

"You're right." Goggle-head started to walk towards a bench and Tsuna followed him as he spoke again. "But I don't understand. Why did you all decide to go on board? Tell me." At the last part he looked at the boy in the jumpsuit who had lazily one eye closed his unfinished chocolate still in hand. "Why do you ask? As if I had a reason for everything I do."

"Yeah, but…" The auburn-haired boy now sat with his back straight and both eyes open as he told him to go first. "Why did you go on board?"

In response the goggle-head sighed. "Well, I don't know," he averted his eyes for a moment before looking back at the boy before him. "I suddenly had this weird feeling and I just knew I had to do this!" His expression turned sour when he heard the blonde behind him giggled.

"Well, I decided to go because I thought this might turn out to be fun."

After she told her reason to be here, the boy in the jumpsuit leered at her for a moment before grinning. "Is that true? Because I thought the same." Suddenly he leaped out of his seat to which the goggle-headed boy had to step aside. The auburn-haired one pointed with on finger at himself and excitedly introduced himself to the blonde.

"Hehe, I'm J.P. Shibayama and what's your name?"

"My name is Zoe Orimoto." Goggle-head then took a step forward and introduced himself as well. "And I'm Takuya Kanbara, nice to meet you."

Deciding it was her turn, the brunette stepped next Takuya and smiled at them. "Hi, I'm Tsunayoshi Sawada but call me Tsuna. It's nice to meet you as well." The look J.P. gave her when he noticed her creeped her slightly out so she took one more step to be nearer the one she was most familiar as of yet: Takuya. When he then the name of the last one asked they all turned their attention to the small boy as well. The reply they got was a quiet one.

"My name is Tommy Himi." The way in which he curled into himself worried the young Decima so she neared the boy. "Hi Tommy."

"Actually I didn't want to go." His shoulders shook and the brunette took another step towards Tommy while the others continued to watch. "I didn't want to… I didn't want to go…I – I – I didn't want to board the train." The boy sniffed and then finally he turned his tearful face to them. "They just shoved me inside!" As soon as he said that, Tommy felt himself embraced in the arms of the girl who introduced herself as Tsuna. Said girl was about to say something when the train entered a tunnel and the lights turned off; it was dark. All of a sudden the train jerked which caused them to fall to the ground. The mafia boss-to-be strengthened her grip on Tommy and took brunt of their fall. She opened her eyes when she felt her body pulse but as abruptly as it came the feeling was gone.

Seeing something glow the brunette turned to the source and watched as amazed as Takuya as his phone changed shape. "What you are holding in your hand is called a D-Tector. Welcome to the DigiWorld," they all heard the familiar feminine voice from their messages.

"Welcome to the DigiWorld?" Tsuna questioned and heard Takuya do the same.

The next moment they left the dark behind and the lights turned back on. They all slowly stood from the ground and the brunette turned to the boy in her arms. "Are you alright?" she asked him softly and when he replied in the positive she relinquished her hold on him. Once she did that the two of them turned to look a t their own D-Tectors like the other three were already doing. Her own had a silver colored main body while the grip was a light aquamarine. Then they all put their hands on their ears in pain when they heard a loud howl. Once it died they released their ears. "Did the train cause that? That's horrible!" The others said nothing but definitely agreed with the sentiment. The next one to speak up was Zoe and what she said had all their attention to the windows.

"Look, what are these weird things?"

"That are birds or not?"

"Birds? I don't think so."

There out the window they could see the sky and out there floated a group of white blobs with faces. When one of them pressed themselves to the glass they watched in fascination as its cute face turned into a grimace which had Zoe screaming. After that the beings went away, though a question remained: "Where are we?"

Takuya was the one who voiced it out.
.

The train finally came to a halt and when the doors opened they came face to face with a group of grey beings with two long and limp ears like a hare's with really creepy expressions. Or maybe it's just me? The brunette turned to her companions. Nope. No, it's not just me. She turned her attention back towards the creepy things when they spoke up. Huh…they can speak…somehow I think I should be more surprised than this. Well, nothing one can do with talking and gun wielding babies, not to mention time-travel and dying will flames.

"What are those...I think that are humans…look…look…"

Suddenly the group of five felt pressure on their backs and before they could do anything they were tossed out of the train. "Or did you want to stay inside forever?"

They all lay on the floor of the platform and turned their heads in amazement. "That is crazy, the train can talk!" Tsuna only nodded in agreement.

"I'm no train. I'm a digimon and my name is Trailmon. You are now at the Flame Terminal which is a digimon town." The young Decima tilted her head in question as she repeated what they have just learned. In response to her action the group of creepy digimon surrounded them while agreeing with the statement that this place was a digimon town.

The five of them grew uneasy with the situation they were currently in and the fact that Trailmon had just left them wasn't helping either. When Tommy started crying the brunette took him into her arms and backed away from the crowd to Takuya's side. There she tried to quieten the boy's cries but before she could say anything he got out of her grip and ran towards the train tracks. "Tommy!"

"I want to go home! I want to go home!"

The moment the boy ran Tsuna and Takuya had stood up and were right behind him, trying to get him to stop. When Tommy went on the tracks she saw Takuya stop, instead opting to shout. Tsuna however didn't and without a second thought joined the distressed boy on the tracks in the balancing act.

"Be careful! Tommy stop! Alright! If you want to go home so badly then I will bring you home!" She heard him yelling from behind her and saw that it had the reaction they wanted: he stopped. "You heard what the Trailmon said, didn't you? We have to find the spirits, then we're able to go home!" Finally the boy turned around. "Really?" They anxiously waited as he tried to walk back but then watched in fear as he lost his balance and began to fall. "Tommy! Tommy!" The two of them cried in alarm. "I'm okay," he nervously answered the pair and they both let out a breath they didn't know they had held in relief. The brunette was already halfway to the boy but was distracted with the commotion she heard from her right. Turning her head she watched in horror as part of Flame Terminal went up in sickly green flames.

A pair of two digimon then came running towards Takuya in full blown panic and ran him over causing him to fall on his behind. She didn't hear what was said but didn't need to, to understand the situation when she saw another more vicious looking digimon walking out of the flames. Once it started spewing flames out of its mouth to attack Takuya she didn't waste another second and hurriedly went to where Tommy still was. When she reached him she immediately held him to her and looked back to Takuya only to see him running towards the two of them who as he arrived on their spot held onto them both. The two digimon she saw earlier were currently settled on his shoulder yelling something aubout fractal codes that she didn't understand.

What she did understand was that part of the land, in fact the one connected to train tracks they were standing on, was disappearing. When it was completely gone the track tilted over causing them to lose their halt and with that they were falling. They could hear J.P. and Zoe calling for them but couldn't concentrate on that. Luckily for them their fall wasn't that deep so they weren't really injured, maybe some bruises but nothing serious.

During their landing Takuya's D-Tector had fallen from his person on the ground and began to glow. They watched on in wonder as a beam lead to the flames in front of them. When the beam faded the red flames turned into a blue colored pillar with something appearing inside it. "That…that is a spirit," one of the two digimon with them exclaimed and they all stared in amazement at having found one.

"So that is one of the spirits." Takuya's expression turned to one of determination. "I will get it." He stood up. "Then I can bring Tommy home!"

Tsuna smiled at the reason and let him take care of their situation. Besides she had a feeling this one truly belongs to him. "I found one finally! I finally found a spirit!" Turning around they were alarmed to find Cerberusmon running towards them. Takuya who was the only one currently on his feet took glance at the trembling Tommy in her grasp and that was all the motivation he needed to pick up an iron rod that was lying around and confront Cerberusmon. "I won't let someone like you have the spirit."

When the digimon got past him he quickly grabbed onto its tail and thus landed together with Cerberusmon in the pillar of flames though while those burned the digimon who jumped away due to that, they didn't burn Takuya.
.

"Execute – Spirit Evolution! …Agunimon!"

"That's impossible; a human doing a digivolution?" Cerberusmon exclaimed. Looks like it, thought Tsuna, a wide grin on her face. From above them she could here J.P. and Zoe. "Takuya turned…"
"…into a digimon," finished the blonde while next to the brunette the white digimon who she still didn't know what he was called with, searched something in that book of his that she didn't know from where he took it. After a while he seemed to find something because there was a sound of triumph coming from him though what he said next was interesseting to know. "Like I thought, he is one of the ten legendary warriors: Agunimon. He is the warrior of fire."

Chapter 1 : end.

Well, yeah, I know I left the fight out but personally that wasn't important for me. This story as a whole won't have a plot with many details. I will mainly concentrate on the things which are the reason I decided to write this story in the first place: Tsuna x Koji. Another reason is that those that are reading this story should already have seen Digimon Frontier so most is self-explanatory; also if something is left out like the fight in this chapter then you can assume that it went like the one in canon. So if you are to leave comments regarding those points then leave it, cause I won't change that and if you don't like that, then don't read it.
