Kamen Rider Fourze: Infinite Cosmic Kita!

(Unknown Location)

I stalked through the shadow, making sure not even an inch of me stepped out of it as I moved along the walls. Despite my title, my stealth skills were second to none. Minutes later, I started to hear voices. There were five of them, all men.

"…and I hope you'll choose wisely, or else we can't guaranteed your brother's safety." One of the voices spoke. Peeking my head out, I saw the five men gathered in front of a screen. On it was none other than the strongest IS (Infinite Stratos) user, the Brunhilde, Chifuyu Orimura. And right before the link was cut, I saw that the woman's expression was one of extreme rage. I could relate.

Quickly, I went back into the shadows and searched everywhere for their captive hostage.

Now, I bet you're all wondering at this point, 'what the hell is going on?' Well, to explain, I was on my way home back from school when I saw men entering a house. And it wasn't the normal kind of entering; it was the breaking in kind of entering. Quickly, I hid and in the next few minutes, I saw them leave with a kid. Naturally, being the good guy that I am, I followed after them and see that they had just talked with the Chifuyu Orimura and based on what I heard, it didn't take a genius to see that the hostage was Ichika Orimura, the younger brother of the Brunhilde.

Now I can guess a number of reasons why these men are doing this, but with today's society where women had the most power in society, I can guess that someone doesn't want Chifuyu to win this year's Mondo Grosso, an International Tournament that is held every three years that's kind of like the World Cup in a way, but for IS. And to do that, they kidnapped her brother and are forcing her to quit the tournament.

This is what I told Ichika once I found him. What, you think I was just standing around and telling you my monologue? Someone needed saving, I don't have time to stand around.

"Time we get you out of here, kid." I said as I finally untied the rope around him. The rope had been tight enough so that someone Ichika's age couldn't break through, but for someone like me, they were no problem.

…

…

…

Okay, I lied. I just used a knife and cut the rope around him. Happy?

"Who are you?" The young Orimura asked me. But before I could say what my name was…

"Hey!" I turned and saw one of the men at the door. God dammit. "Who the hell are you!?"

Instead of answer, I threw my knife at him where it struck him in the knee. I quickly ran up to him and kneed rush him in the face before he could scream out in pain. He flew back and hit a metal pole, knocked out.

"Okay, I think it's time we left, kid." I said as I quickly went back to the boy, grabbed his hand, and ran. But not before I checked the man and took a gun from him. You can never be too safe.

Of course, getting out was not easy. The other men heard the commotion and went to see what had happened. Since I had abandoned stealth, they obviously saw us. As quickly as possible, me and the kid took cover the minute they started hailing us with bullets.

"Haru Yamamoto." Ichika looked at me in confusion as I took out the gun I snatched earlier. "My name. Telling you in case we don't make it out of here."

"In that case, I'm Ichika Orimura." Ichika smiled despite the fact we were being shot at. Either he's very brave or very naïve. Maybe it's both.

I smiled at Ichika before the bullets stopped pelting us, meaning that they ran out of bullets. Quickly, I stepped out from the cover and landed three head shots. In the famous words of Darth Vader: All too easy.

"So, you're what's causing us all this trouble." The fifth and final man appeared, arms crossed behind him as his face was filled with arrogant confidence despite the fact that he was alone and I still had belts left to use. He's got something planned out.

I pointed my gun at him. "Who ordered you to kidnap Ichika?"

"Do you really expect me to tell you that?"

"Point taken." I said. "My guess is that it's one of the contestants in the tournament or maybe is a supporter, who knows. But I will find out once we get out of here."

"Ha!" he laughed. "You really think you'll get out of this place alive?"

"Uh, I have a gun. I assumed."

"Well then, allow me to enlighten you." The man said before took out…oh you have got to be kidding me.

A Zodiart Switch. He pulled out a Zodiart Switch. Well, at least I have a new lead now.

The man pressed down on the red button and in a blast of dark cosmic energy, in place of the man was the Hound Zodiart.

Ichika gasped and froze in fear, but he didn't scream. Got to give props to him. Kids his age would be screaming at this point.

"So, you're a Zodiart, huh?" I said as I threw away the gun. It wouldn't help anyways.

"So, you know what I am. That's surprising. Tell me, who are you and why are you trying to help the kid? I know for a fact that you two have never met until now."

"I'm just helping him because I want to. As for who I am…" I pulled out the one thing that could help me and strapped it to my waist. The belt materializing and wrapping around me. I then flipped the red switches.

3!

The Zodiart and Ichika looked at me in confusion.

2!

I placed one hand on the lever and placed my other arm front of me.

1!

"I'm the guy who's gonna kick your ass! Henshin!"

I pushed the lever and raised my right hand in the air as steam or smoke suddenly blasted out of my Driver, almost blowing Ichika away. Then two hologram metallic circles appeared below me and above and the next thing I knew is that I'm in an all too familiar outfit for me. I've watched to show so many times that I memorized what I was wearing to heart. I was wearing a sort of white space suit on. I had on a helmet that was shaped like rocket and the lenses were orange. I had an orange circle on my right arm, a black square on my left arm, a blue X on my right leg, and a yellow triangle on my left leg. I also had a jet pack on my back which is neat! I have become Kamen Rider Fourze!

"Whoa~!" Ichika looked at me in awe with stars in his eyes.

"What the!? What the hell are you!?"

"Me? The names Kamen Rider Fourze." I said. "Let me tell you. Being a Kamen Rider is not easy. You chase after an evil organization and the next thing you know, you're in place you don't know. But enough talk. Let's settle this one on one! Oh and before I forget."

I crouched down, clenching my fist before I shot up and raised my arms high in the air as I yelled out.

"Uchu KITAAAAAAAAAAAAAAAAAAAAAAAA!"

And done! Well, there you have it. A Fourze and Infinite Stratos crossover. I had a difficult time thinking of what to crossover with Fourze until a fellow author gave me the idea. Look out for this story in the future. Until then, this is Ashbel Longhart, signing out.
