I don't own Fairy Tail or Kamen rider Build.

Chapter 2 : A world of unknows and excitement

/- Near Hargeon -/

Pain. It seems to be the only thing Sento Kiryu could feel right now. He could easily guess that he was on the ground, a mossy one at that. He could feel it at touch, as it was the only one of his 5 senses that seems to be working at the moment. He got up with difficulty, trying to straighten himself before opening his eyes. When he had finally stand up completely, he immediately notices something weird around him : he was no biologist, but he was intelligent enough to know that half of the plant around him seems to be out of this world, or out of HIS, to be more precise.

Finding his bag a few meters away, he noticed that his bag was open, and seems pretty empty. Rushing to it, he looked inside and found : his Build Driver, his Build Phone, the Rabbit Fullbottle, the Tank, the Lion and….

Nothing else.

- "WHERE ARE THE OTHER FULLBOTTLES ?!", he shouted "MY SPARKLING BOTTLE ? MY HAZARD TRIGGER ?"

Sento start to feel bad. He was in this world since less than 2 minutes, and he has already lost 98 % of his possessions.

- "This sucks.", moaned Sento. In the other hand, seeing how I arrived, it was to be expected.

Indeed, when Sento jumped in the portal, there was 2 things he didn't think of. First, the fact that going through this portal would be the same as being stuck inside a washing machine. Second, the exit. He was literaly expeled of the portal like a bullet out of a gun. And of course, the exit was high in the sky. With everything, the fact that his bag opened and scattered his content across this place. So now, he had 2 missions : find Shocker AND find all his scattered devices.

- "What a nice start.", said Sento in a sour tone.

Deciding not to let himself be defeated, he straightened himself and saw a port city quite close to him.

- "Well, I have to start somewhere", he said before going to the city.

/- Hargeon Train Station-/

- "E-Excuse me, sir ? A-are you okay ?"

It was a train controller. He was speaking to a young who, obviously, was in a bad shape. Dressed with some large white pants and an open vest, revealing a tone and slim body, this salmon haired guys, named Natsu, was sprawled on the ground, sickly pale and breathing heavily.

- "Aye. It happens all the time.", answered Happy, a blue talking cat.

- "Impossible, I'll never ride a train, ever again.", said Natsu while getting up… before turning to the window, feeling nauseated again.

- "Let's go. If the info we got is correct, Salamander should be in this town.", declared Happy while getting off the train… forgetting Natsu inside when the train started to leave the station, taking him along.

- "Ah… it departed already." Happy just said, watching it leave. "Hum ? What is that ? "

His eyes were laid on something, just outside the station near the rail. It was a really small bottle, white and kinda transparent, with some kind of design on it. It has a small cap, with the letter H on a white background and a S on a red one. Finding this thing kinda cool, he put it in his bundle and take off to get Natsu.

/- Hargeon's streets -/

- "Tch, he only gave me a 1000 jewels discount." Complained a blonde haired girl with brown eyes named Lucy. "IS MY SEX APPEAL ONLY WORTH 1000 JEWELS !? »

She just had bought the silver key of the canis minor constellation, and her attempt to seduce the seller didn't worked as much as she hoped.

The young mage then noticed a large crowd of girl forming on the other side of the street.

-" Hum, what is happening over there ?", she asked herself

- "A famous mage is in town ! It's Salamander-sama ! ", she heard some girls running beside her.

- "Salamander ?", she repeated before beginning to smile widely. "You mean the mage who control a kind of fire magic that you can't learn in books ? I wonder if he looks cool."

Having said that, she started to approach the crowd. When she was faced with Salamander, she started to feel her heart beat faster and the heat rise to her face.

- "W-What is happening to me ?", she asked herself.

Like drawn by some kind of invisible force, she then started to approach him when …

- "IGNEEL ! "

Lucy instantly snapped out of her "trance". Natsu, who just came back from his second train ride, had jumped out of the crowd, searching for Salamander. But when his eyes met Salamander's…

- "Who are you ?", he simply asked.

He then leaved, not even letting Salamander introducing himself, which made the fangirls catch him, dragging him back to excuse himself to their idol, who instantly calmed down when Salamander asked them to, making them swoon at him, right in front of a Lucy, who grew more and more suspicious. Salamander finally leaved, using a cloud made of some kind of crimson fire to fly away.

- " What is he ? ", asked Natsu to no one in particular.

- "He is really disgusting. ", ansxered Lucy, forcing Natsu and Happy to turn to her. "Thanks for earlier."

/- In a restaurant -/

- "Yhurr ah naiz burrzon. (You're a nice person )" said Natsu while engulfing inhuman quantities of food.

- "Ah ah, so you're Natsu and Happy, right ?", said Lucy, being splashed with sauce, thank to the way the two were eating. "I understand you, so just eat slowly."

- "That Salamander guy was using magic called charm.", explained Lucy. "It's a magic that attracts other people's heart to the caster and it was banned many years ago. But trying to get girls attention by using this magic… How disgusting. Though, thanks to you, charm on me wore off."

- " I see ", simply said Natsu

- "I may not look like this, but I'm a mage, too.", she continued, the other two not really listening. "I'm not a member of any guild yet, though. A guild is an association for mages where they manage jobs and information for mages. But there is so many guild all over the world~, and it's hard to get into the popular one. Many great mages will gather in the one I want to get into."

At this point she seems lost in her own world, not noticing Natsu and Happy who were looking at her like she had 2 heads.

- "Ahh what should I do !?", she continued. "I want to get in, but I bet It'll be hard… Ah sorry, you wouldn't understand a story from the world of mages, would you ?"

She stooped herself and said, calmly this time.

- "But I'll surely join that guild. I bet I can get many big jobs there."

- "I.. I see…", said Natsu, still shocked by Lucy's monologue

- "You talk a lot", said Happy aboveboard.

- "By the way ", said Lucy, ", aren't you guys looking for someone ?"

- "Aye. It's Igneel."

- "I heard that Salamander is coming to this town.", explained Natsu "So we came, but it was the wrong person."

- "This salamander didn't look look a salamander.", noticed Happy

- "How could…a human look like a salamander ?", questioned Lucy, clearly not understanding.

- "Hrm ? Igneel is not human.", answered Natsu like it was normal. "Igneel is a real dragon."

Lucy reacted in a pretty normal way, considering what she just heard : she flipped out, eyes bugging out of her head and jaw falling.

- "THERE'S NO WAY SUCH A THING WOULD BE IN THIS TOWN !", shouted Lucy, and judging by their reaction, Natsu and Happy just realized something. "HEEY ! DON'T TELL ME YOU ONLY JUST NOTICED !"

Calming down, she stood up, ready to leave, but not without leaving a little money to them.

- "I guess I better get going… but go ahead and take your time."

Seeing her actions, Natsu and Happy, tears in their eyes, threw themselves on the ground and start bowing to Lucy, embarrassing her. Then Happy got an idea. He took the strange bottle out of his bag and gave it her.

- "Here, it's to repay you for your kindness.", ha said handing the bottle.

- "Hum, thank, i guess.", she said. As she leave the restaurant, she looked at the bottle. This might be a rare magic item, i've never seen anything like this before. She thought. Well they were nice, kinda, so I'll keep it to remember them I guess. With that, she smiled and walked away.

/- Timeskip. Evening. Hargeon's streets -/

- "It sucks."

That was basically all that Sento was saying for the whole day he was in Hargeon. It's not that everything was bad : people were talking in the same language and the food and beverage (offered by some kind people) while being strange, were really good. But that was it for the good point. He had no money, or at least nothing usable in this world, so he couldn't buy anything. He tried to understand how this world was working, if there was a president, king or anything like that but he wasn't a big fan of politics and was completely lost. But what bring him down the most was the fact that this world was not a world of science or technology like he hoped, but a world of magic. He, Sento Kiryu, the greatest genius ever (according to him), was stuck in a world were his knowledge is unusable. Now that it was night-time, he was starting to think that he will have to sleep outside.

- "If only I had brought a tent or something.", he complained.

Having reached the coast, he sat down on the sand and stared, not knowing what to do, a position he never experienced before since he always had a plan for something. That when he saw something, a boat who was heading to the beach he sat on at great speed, propelled by a giant wave.

- "…Wait ? WHAT !?", he realized just before running to put himself to safety when.

*CRAAAACC*

The boat landed in a deafening crash on the sand, getting the attention of everyone in the city. Sento watched the boat and saw something that made him go wide eyed : a mermaid, carrying some sort of vase, before disappearing in sparkles of light.

- "What the hell was that ?", he asked to himself.

He looked again at the boat. His hero's instinct asking him to go check if someone need help, and so he go to the boat. Using the Rabbit Fullbottle power, he climbed the boat and head straight to the cabin. He just had time to look inside when he saw a man throwing fire to a younger man, setting him on fire.

- "Natsu !", a girl shout but was held back by a blue cat with wings

A blue flying cat, thought Sento, well I just saw a mermaid so why not. But I have to help this guy.

- "Awful."

Hearing this single word, everybody stop and turned… to the burning guy who was standing like he was perfectly fine. And he was.

- "What is it ? Are you really a fire mage ?", asked Natsu. "I've never tasted such awful 'fire'."

Much to the shock of Sento, that was actually EATING the fire. "What kind of monster his this guy ?" thought Sento, "is that how magic work here ?" Turning his head he saw that everyone was as shocked as he was. "Apparently not." He deduced.

Just after eating this fire, Sento saw Natsu taking a big inspiration while pulling his head back and knew that something bad was coming.

- "Bora-san ! I've seen him before !", said a thug to his boss. "Rosy hairt and scales-like scarf.. There's no doubt he his…the real."

He never finished his sentence since Natsu, putting his hand in front of his mouth had shouted, like a war cry.

- "Karyuu no hokou !"

And then, a stream of fire came out of his mouth, destroying the room and knocking out all the thugs, except the boss, who seems ready to piss himself.

- "…The real Salamander." Concluded Lucy.

Then, after knocking down the boss, Natsu kept knocking bad guys after bad guys. Sento was captivated by the way Natsu was fighting, but he then heard the end of Happy's explication about Natsu's power.

- "Dragon slayer ! Igneel taught Natsu this.", he finished

- "It's weird that a dragon taught someone a dragon interception magic, isn't it ?", said Lucy and seeing Happy's face, continued, "But you didn't doubt it at all, huh?"

"A dragon taught someone how to kill a dragon ? With every seconds that passes, I'm sinking in weirdness here."

He looked again at Natsu and immediately noticed something : he had beaten everyone, but destroyed half the port while doing it.

"Does he even know how to restrain himself?", he said to himself

But then, the boss, Bora or something like that, stood up, rushed to Lucy and took her in a strangle hold, taking her hostage. Lucy started to fight back and Sento was ready to jump in but he then saw something strange, but also familiar. Some kind of whitish energy came out her bag, covered her back and then…

*SHING*

Needles came out of that energy, piercing Bora. It doesn't killed him, but let go of Lucy with a cry of pain. Bora then tried to run away, but Sento, sensing that this guys wasn't a beginner in the bad guy world, knew he had to jump in now. "This girl, she just used Harinezumi ? Well, for the moment I have to catch that guy. How can I call myself a Kamen Rider if I let that guy leave, I already let to many things happen."

He took out the Rabbit Fullbottle, shook it and, harnessing the power from the bottle, rush at a blinding speed to Bora, knocking him out in an instant.

But then, he saw some kind of army coming his way. Normally, seeing law enforcer wouldn't be a problem for a hero like him, but he saw that the blonde girl, the pink haired guys and the blue cat were fleeing the scene. He then remember that this girl had the Harinezumi Fullbottle, so he had to follow her to get it back, but he also realized something that made his hair rise up in excitation and a wide grin cover his face : if a girl with magic power could harness the power of the Fullbottles, then there have to be a way to understand magic by approaching it like a science. Excited by all the possibilities it could bring, and the ways it could help him in his mission of finding Shocker and his lost equipement, he then bring out his Build Phone, put the Lion Fullbottle inside to form the Machine Builder and speed out to follow the three mages.

So, second chapter done ! I hope you'll like it. As I said in the first chapter, it's my first story and I'm kind of building it on the moment. SO if you have any advice or remark, please review to help me. In the next chapter : Sento met up with Natsu and Lucy. The Rider enter the guild. Will they help him ? And where is Shocker exactly ?
