After the incident few months ago, the moon suddenly explode and it turn into cresent shape. Something or someone have turned the moon into that like it was nothing. The culprit is best of the best.

Somewhere else...

The city is busy like always. With many cars, lights, people, except for the higher buildings. It shines with lights that can be seen from bellow. Under the moonlight, a figure is standing on top one of the tall building and then the figure disappear from the sight.

Inside the building...

The figure is shown a person. He's wearing a ninja outfit with other features. He have helmet with two strand of tied hair at both sides, two large orange eyes, green belt with pink lever and a game like cast at it and orange highlight, grey-black and white ninja outfit.

???: Let's see. My target this time is in this building.

Then the visual shows heat signature of the people inside the building. He walk quietly while looking around.

???: Now... Where are you?

As he walk past the hallway, two guards come out from a room as a pixelette gun appear in his right hand. He come out from behind the wall and shoot them. Both of them down, but not dead, just fallen asleep due it's not a real bullet.

???: Sleep tight there.

While walking, he keep shooting the guards that are guarding the area. Then he reach an elevator. He press the button and wait for the elevator to arrived. As the door opened, he enter the elevator. He press the top floor button and the door closed, as it moved upward. He take out a game console and start playing games while waiting.

???(In mind): I wonder why my target this time is a bit weird? But using a child in my age for weapon... That is one thing I can't forgive!

Without him knowing, dozens of guards are waiting in front of the elevator at the top floor, ready with their guns and tazers.

"This is where he'll end up dead."

"If I remember, that assassin that came here is only target corrupt, bad, evil and false using power people. I wonder why he target out boss?"

"Well, our boss aren't that good person. He did many things that involved high crimes and the latest one is more like bad enough."

"Who cares about that. If our boss died, who'll pay us money?!"

They all ready themselves as the elevator arrived. As the door opened, the person isn't even in the elevator at all. Only the game console he played is on the floor.

"Huh?"

"Where did he go?"

A guard went into the elevator and look around before grabbing the game console from the floor. He turn it on and a word shown at the screen.

"Look behind."

"Look... behind?"

The guard turn around and saw the person is standing right behind all the guard.

???: Hello.

"There he is!"

"Shoot him! Shoot!"

???: *sigh* Here we go again.

(Short Time Skip)

After some shooting and slamming sound, it went quiet. In this huge room/office, a man is sitting at the table. He's clothes is all white along with a mask like hood, with only small opening that show his eyes. The man is Shiro, the target. As the door opened, it shows the person comes in. All the guards behind him all down as he closed the door.

Shiro: I impressed that you able to beat my guards in such short time.

???: They're not even that challenging.

Shiro: I see.

???: Now, let's get back to business.

The gun disappear from his hand and replaced with a ninja sword with an inserter at the middle part. He walk slowly toward Shiro until he reach and stopped.

Shiro: I never expected that I'm going to become the target of the famous assassin...

As the cloud clears, the moonlight slowly shows the assassin that targeted Shiro.

《Kamen Rider Fuuma》

Shiro: The Gaming Ninja, Fuuma.

Fuuma: I was called that all the time when I was about the kill my target. But why are you so calm?

Shiro: Is it wrong?

Fuuma: No, it's that my target always begged for their lives before I kill them.

Shiro: Well, I'm not one of them because... *snap his fingers* I have something they don't.

Suddenly, something really fast hit Fuuma before he can react and sent him skidding away a bit far from Shiro's table.

Fuuma: What the?

Shiro: Ho? I suprised you can handle that.

Fuuma: Who... are you?

Shiro stand from his table and went in front of it. A boy that look like in the same age as Fuuma is standing beside him. The moonlight shines behind him so he can't see how the boy looks like. But he can see four light blue tentacle on top of the boy's head.

Shiro: My finest creation.

Fuuma: What?

Shiro: Do it.

The boy move in high speed toward Fuuma but he able to react in time and deflect the tentacle from hitting him. Fuuma barely able to deflect the tentacles from hitting him but the last one hit him hard and sent him at the wall. A crack appear behind him as Fuuma fall to his right knee.

Fuuma: *panting* What is... with that tentacle?

Shiro: Suprised? Like I said, this is my finest creation.

Fuuma: Really? Tentacles?

Then they heard sirens. Shiro look from the glass window and saw some police cars and trucks just arrived. Then he turned back to Fuuma who is standing properly.

Shiro: I apologize, it's look like we have no time to chatting. Unfortunately, I'll be taking my escape. Let's go.

Then the boy swing his tentacles around and slam the floor causing some dust cloud. As the dust disappear, it shows Shiro and the boy is gone.

Fuuma: Geez... It's look my job here isn't really done. I'll definitely find you.

He move his hand and press the button at Kimewaza Slot at the right side of the belt.

-Stage Select-

He disappear into pixels, and teleport away from the area before the police find him.

(Time Skip)

At Japan Ministry of Defense...

The people are having a meeting about the incident that happened. The moon change into cresent shape and the shocking encounter of the culprit himself.

"So, how was the assasstination of that creature?"

"It seems that the students are still having hard time on trying to kill it. How can we deal with the something like this?"

"After looking at the data of many assassins, I think we have the perfect one to do that job. Show it."

C. Programmer: Yes, sir.

Then it shows the data of Fuuma. All the target he killed, his skills and the video of all security camera at the place where he kill his target.

C. Programmer: Here's the data, sir.

"Who is this?"

"The famous game assassin, Fuuma."

"Fuuma?! Why would we should asked the help of someone like that?! He's completely the enemy of society himself!"

"No, that is what some people wanted us to see. Here, take a look of these."

One of the member put some papers on the table. The others look at the papers and the one that written on the papers are about Fuuma's target.

"I can't believe. He only target those who involved in crimes."

"Some of his target was part of the government but the people hate them. So he deal with the corrupted people in the government."

"That is why I think he's the best person to go and kill that creature."

C. Programmer: Here's more about him, and his personal data.

"We've been keep on eye on him. His real name is Aizawa Tsurugi, and he's a junior high schooler. He's 15 years old so he does fit with the job, and it also can help him with his education."

"Can we trust him?"

"Of course. Ever since we've been watching them, we did make some deal with him about assassinating anyone that was should be killed. He's more to a normal teenage boy than cold blood killer."

"Right. We'll accept that opinion."

"Tell Karasuma to meet with Fuuma and tell him about his next job."

C. Programmer: Yes, sir.

(Time Skip)

At Tsurugi's house...

Even after fail at his job, he didn't felt down at all. He easily cheer up when played game. After taking a bath, he change into his casual house outfit. His house is a normal two floor house. The decoration in his house mostly about ninja, games and animes.

Aizawa Tsurugi has spiky purplish-dark blue hair with bluish-green eyes and always wear headband with game badges. He is very skilled assassin but still have a normal live and he's a junior high schooler. He's a genius so he can easily pass exam. He also the champion in both national and international solo gaming tournament.

Tsurugi: *sigh* I can't believe I fail in this job...

He take a can of soda from the fridge and went to the living room as he sits on the sofa. He open the can and drink it. While drinking, he heard the door bell. He put the can on the table as he went to the door. When he opened the door, it was Karasuma. Karasuma Tadaomi is an adult middle aged man with spiky black hair and black eyes. He mostly seen wearing suits.

《Karasuma Tadaomi》

Tsurugi: Karasuma-san.

Karasuma: Tsurugi, do you have time.

Tsurugi: Yes.

Karasuma comes in and Tsurugi serve him a cup of coffee as they sit in front of each other.

Tsurugi: So, why are you here? Is it something with my last job?

Karasuma: No, it's about the cresent moon incident.

Tsurugi: If I remember, something destroyed part of the moon, turning it into cresent shape.

Karasuma: Well, you're right about that. I'm here to offer you another job.

Tsurugi: What kind of terrorist boss you wanted me to kill now?

Karasuma: It's not terrorist boss, it's the one that blow up the moon.

Tsurugi: You guys found the culprit already?!

Karasuma: It's more like he reveal himself to us. *give Tsurugi a picture* Here is his picture.

Tsurugi take the picture and examine it. It was the picture of hige octopus humanoid with yellow body and wearing gradution outfit.

Tsurugi: What is this? Somekind of octopus or alien?

Karasuma: He told that he was the one that destroyed part of the moon. Also, he's not an alien, he's live and raised here, on Earth.

Tsurugi: It almost doesn't make any sense at all.

Karasuma: Well, you did make some things that doesn't make any sense either. Create weapons and power based on your favourite game.

Tsurugi: Well, that is who I am. So what is his demand?

Karasuma: He said that he'll destroy Earth in the next March. Also, he wanted to become a teacher.

Tsurugi: A teacher?

Karasuma: We don't know what is his real motive. But we come to agreement that he won't harm the students. Also, the students are giving weapons are harmless human but can harm that octopus.

Tsurugi: In other word, they get the chance to kill that octopus teacher in extremely close range, huh?

Karasuma: That's right. And the reward of success is... ten billion yen.

It makes cashing sound. Tsurugi's mouth open wide as his eyes change into golden yen symbol.

Tsurugi(In mind): With that money, I can buy almost all games in the world! No, wait! I have money because the government pay me and the bounty money as well! *shake his head* Just forget about that money! It can help others that needing it!

Karasuma: So, do you agree with this job?

Tsurugi: *nod* Yes.

Karasuma: That's right. You need to transfer to the school where he teach, and at the same time graduate junior high from there.

Tsurugi: I'm just fine.

Karasuma: You just genius than normal student would be.

Tsurugi: Which school I supposed to attend in?

Karasuma: Kunugigaoka Jr. High School, third year, Class 3-E.

Tsurugi: *irritate* Tch. That school, huh? Things just make my life even worse than before.

(Time Skip)
(Next Day)

At Kunugigaoka Jr. High...

Tsurugi, in his new school uniform, is standing in front of the school. Just hold his school bag at his right shoulder. Unlike the school he from, this school is the last place we wanted to be at.

Tsurugi: The worst school over...

He walk at the school. He walk past the school ground and walk into the village part of the school where it was outside the school satellite.

Tsurugi: I can't believe that they make the worst student come here.

As he arrived, he saw an old campus like old wooden building with no air conditioning and all old school items. The only place where the worst students will go when they fail just even once. Class E is located in the mountains one kilometer away from the main campus.

Tsurugi: At least these guys here know about friendship. Then... here comes my new life in this school.

At Class E Campus...

The huge yellow octopus, Koro Sensei, is teaching the class about the current studies.

Koro Sensei: Before we continue, I have a good news for you guys.

Yuma: News?

Koro Sensei: We'll have a transfer student joining our class today.

The whole went silent before they all become excited.

Everyone: A transfer student?!

Yuma: Who is this tranfer student?!

Hiroto: It's a girl?!

Rio: Will it be a boy?!

Taiga: I hope it's a cute girl!

Hinata: I'm hoping a hottie!

Ryoma: Heh, who cares about transfer student.

Kaede: Hey, Nagisa.

Nagisa: Yes?

Kaede: Who would transfer to this class? Everyone knows that Class E is the worst.

Nagisa: I don't know. Maybe the transfer student is the same as us, a failure.

As the door opened, they all look at the door. Tsurugi comes in with usual face and normal smile as he stops and look at the class.

Tsurugi: Nice to meet you all. I'm the transfer student, Aizawa Tsurugi. Just call me Tsurugi. I hope we able to get along.

Koki: He's kinda look... cool.

Yuma: Is this guy a game freak?

Tomohito: Stil... he doesn't look that bad.

Koro Sensei: Nice to meet you, Tsurugi-kun. I'm the homeroom teacher of this class, Koro Sensei.

Tsurugi: Nice to meet you, Koro Sensei.

Everyone(In mind): He just act casually?! He doesn't even suprised seeing our teacher is not a human?!

Tsurugi: Right, Sensei.

Koro Sensei: Yes?

Tsurugi: Look out.

Koro Sensei: Hm?

Suddenly, in just a blink of eyes, Koro Sensei's left tentacle was cut with Tsurugi hold the anti-sensei knife.

Koro Sensei: Huh?

Tsurugi: I told you, look out.

Koro Sensei(In mind): I didn't even see his move! He's fast like they always said!

Tsurugi: Sensei's speed is Mach 20, along with shedding skin ability, change colors, and bulletproff. It's better to attack when you don't move!

Koro Sensei: Interesting, come at me!

He move in high speed as the students cover their face with their hands. Tsurugi's eyes keep glancing around the class for Koro Sensei as he take out an anti-sensei BB and put it between his fingers. He point and a direction and flick his fingers as the BB hit Koro Sensei's right tentacle when he stops.

Koro Sensei: Kyahh!

Tsurugi: Sorry, Sensei. But when look at your speed, if I predicted the timing when you stopped I can hit you.

Nagisa(In mind): Wow! Just one look at Koro Sensei, he able to hit him! He's the first one, the first one that ever hurt Koro Sensei!

Then Koro Sensei's tentacles grows back.

Koro Sensei: That was an impressive move, Tsurugi-kun. I expected that the Ministry of Defense transferred you here.

Tsurugi: Well, I got a job I can do all the time.

Koro Sensei: It's because you fail to assassinate your target yesterday, right?

Tsurugi: *suprised* How do you know that?!

Koro Sensei: This is how.

He take out a tablet and show the security camera of Tsurugi as Fuuma. The camera is damage a bit so it only show Fuuma. Shiro and the boy aren't visible so they don't know how they look like.

Koro Sensei: Well, you're still young and there's a lot more to learn from here, Tsurugi-kun. No, or I should say, one of the best and the youngest assassin ever, Fuuma.

The students look at each other as they confused.

Koro Sensei: This is time for class, we can continue later outside.

Tsurugi: *smirk* Oh? Sensei is more interesting than I expected.

(Time Skip)

After the class, it's lunch break. Koro Sensei went off to somewhere else. The students just having their lunch like always while they look at Tsurugi. He didn't even do anything after he hurt Koro Sensei.

Tomohito: Hey, Nagisa, he didn't even do anything.

Nagisa: Yeah.

Kaede: Koro Sensei said that Tsurugi is the youngest assassin, but he looks normal to me.

Nagisa: I think so as well.

Tomohito: He don't have that blood thirst and dark nature.

Tsurugi: I won't show that unless I'm doing my job.

Nagisa/Kaede/Tomohito: He can hear?!

Tsurugi: Sensei is late, despite he move that fast.

Nagisa: *went to Tsurugi* U-Um... Tsurugi, right?

Tsurugi: *look up* Yes?

Nagisa: Are you really an assassin like Sensei said?

Tsurugi: Yes, why?

Nagisa: I mean, you're not look like a killer at all. You look like a normal boy.

Tsurugi: That is what you see me like this. I'm only kill when the right time. *give Nagisa a small notebook* Here.

Nagisa: *take the notebook* What is this?

Tsurugi: My kill list.

Nagisa: Your what?!

Tsurugi: Just read it, and you'll know what kind of assassin I am.

Nagisa: O-Okay.

Taiga, Yuma, Hiroto, Kaede and Yuzuki look from his shoulder. Nagisa look at the list one by one and suprised about it.

Nagisa: Th-These guys are... Corrupted people, those that use their power falsely, terrorist... You really are Fuuma!

Yuma: Fuuma?

Kaede: Tsurugi is Fuuma? But I don't know who Fuuma is...

Nagisa: The gaming killer, Fuuma. Your target is only people that trying to destroy the weak, and you're know for playing games during you do your job.

Tsurugi: That's right. Because what kind of assassin won't have fun. Assassination means to be proud of what you did.

It makes them remember what Koro Sensei said before when they use the suicide assassination that they tried.

Tsurugi: Now... *stand up* It's time for the hurricane to rise.

(Time Skip)

After Koro Sensei back, the all gathered at the field. Koro Sensei and Tsurugi stand in front of each other as the others went to the safe distance.

Koro Sensei: *grin* Now, shall we begin?

Tsurugi: Heh, just fine with me!

Pixels appear at his waist and form the Gamer Driver, making the others suprised. Tsurugi take out a gashat and press the button.

-Hurricane Ninja-

The game screen appear behind him as the game area generates and Tsurugi take a ninja stance.

Tsurugi: Henshin!

He spins the gashat twice and insert it into the belt and open the lever.

Gashatto! Gachan! Level Up!

White wind formed a hurricane around Tsurugi as strong wind start blowing.

Maki Maki! Tatsumaki! Hurricane Ninja!

As the wind disappear, it shows Tsurugi in his Rider form. In this look, he us known as Kamen Rider Fuuma.

Fuuma: Now, Koro Sensei. Let the assassination, begin.

Koro Sensei: Show me your skills, young assassin.

-Gashacon Katana-

Pixels appear at Fuuma's right hand and creates a katana. He take a sword stance while looking at Koro Sensei.

Fuuma: En garde.

Both of them make their moves. Fuuma keep trying to cut Koro Sensei but he able to dodge with his speeds.

Fuuma: Fast as always. Then...!

He take out a small yellow coin item. He throw it up and it become big as Fuuma touch it.

-Speed Up-

Fuuma glows in yellow as he dash even faster than before. He keep jumping around and try to hit Koro Sensei until he able to cut one of his tentacle.

Kaede: Amazing!

Taiga: He cut Koro Sensei's tentacles again!

The fight keep getting even more faster as Koro Sensei keep dodging while Fuuma able to cut some more of Koro Sensei's tentacles. Fuuma keep chasing him but his still slower then Koro Sensei making him land on his right knee and panting because of tiredness.

Fuuma: *panting* Sensei is just too fast....!

Koro Sensei: Should we stop now?

Fuuma: No, there's just one more thing!

He throw his sword weapon away and pull the gashat from the belt.

Gashoon!

Fuuma: Feel my hissatsu!

He insert the gashat at the Kimewaza Slot and press the button.

Gashatto! Kimewaza!

Fuuma's body shines in white-grey light and it all went to his right leg as he press the button again.

Hurricane Critical Strike!

Fuuma jumped as he rotates abd create a small storm. Then he burst right toward Koro Sensei in high speed. As the hissatsu hits, it create explosion and cloud of dust.

Tomohito: Wh-What happened?

Yuma: Did he win?

As the dust clears, it shows Fuuma's right feet is near Koro Sensei's face but he get tangled around the tentacles.

Fuuma: Tch! Damn it! Very close!

Koro Sensei: That's right, Tsurugi-kun. So close, but so far. There's more for you to learn.

He put Fuuma on the ground as the other students went them.

Koro Sensei: *look at others* It's true that Tsurugi-kun is an assassin, but treat him well. He really needs a real friends.

Everyone(Except Ryoma's group): Yes, sir!

Koro Sensei: Now, I have some books to check. *walk away* So, go back to your class.

Then Fuuma turn to his classmates as he sigh.

Fuuma: I fail... Sorry, guys.

Nagisa: Don't worry, we didn't able to hit him at all.

Tomohito: Since we have you, we can kill Koro Sensei!

Fuuma: Don't depend on me too much. Also, if we can kill Sensei, you guys can have the money.

Everyone: Seriously?!

Fuuma: Yeah, don't think that I get money just because of assassination I did. I'm great in games.

He de-henshin and talk with his classmates while they heading back to their classroom. When they get to know him, Tsurugi is more kind and caring person than an cold blooded killer. Tsurugi finally have some real friends here. They must kill Koro Sensei before next March or Earth will be history.

To be continued...
