I do not own Kamen Rider Den-O or Assassination Classroom.


Assassination Den-O

A young man was walking to school. He had black hair that covered his ears, black eyes and he wore the Kunugigaoka Junior High School uniform. His name is Jikanmaru Nogami, but people call him Jikan.

Just a few days ago, he met Momotaros, via possession, and witnissed him scaring some people from the main building of his school. He learned about the Imagins and what they do along with DenLiner. In return, he told them about the permament cresent moon and Koro-Sensei, who is the one who caused it.

Needless to say, Momotaros got annoyed by him and tried to slash him with an Anti-Sensei knife.

Jikan is now climbing the stairs to his school, which is on a mountain, and it was a pain to just climb up the stairs.

'Just my luck.' he thought before Momotaros possessed him.

"Jikan! There's an Imagin near your school!" M-Jikan said before he ran torwards to where the Imagin is at.

"Aw man! I just hope Koro-Sensei won't be there!" Jikan yelled in his mind.


M-Jikan ran to the location and he sees a three Mole Imagins.

"Three huh?" M-Jikan smirked and he got his Rider Pass in one hand and a belt in the other. The belt had a red, blue, yellow, and purple next to a circle that had a T with a tip pointing to the right. He placed the belt on and pressed the red button which soon played an electric keyboard kind of tune.

"Henshin!" M-Jikan announced as he swiped the Pass over the circle.

"SWORD FORM!"

Red pixels came out of the belt before forming up on M-Jikan. M-Jikan was now donned in a black bodysuit with a chest plate is black and white with the white parts higher up with a silver line in the center that looks like train tracks. The helmet has a silver line running down the middle with a silver mouth plate and black eyes. This is Kamen Rider Den-O Plat Form.

Soon red pieces of additional armor then appeared on his shoulders and chest as well as black armor trimmed in yellow snapped to his back. A red metal peach slid over the helmet and snapped onto the front before splitting in two, the points extending to become antennae and the two halves of the peach now resembling eyes. This is Kamen Rider Den-O Sword Form.

"Ore…Sanjou!" Den-O SF announced while doing his pose.

"Den-O!" one of the Mole Imagins growled. Den-O SF simply scoffed before grabbing the DenGasher and formed it into a sword.

"Let me tell you guys something. From start to finish, I'm at a climax!" Den-O SF announced as he pointed his sword at them.

"Ikuzo, Momotaros!"

"Ikuze, Ikuze, Ikuze!" Den-O SF said as he charged at the Mole Imagins. He slashed a couple of them before defending himself from the third one's claw before being slashed by his axe hand twice.

"Teme!" Den-O SF exclaimed before he slashed him ruthlessly, making it cry in pain. Den-O SF then slash one of the Mole Imagins, who tried to do a sneak attack.

"Momonoji! Let me fight!" Kintaros said before possessing Den-O SF.

"AXE FORM!"

Just then Momotaros was ejected out of the body while the light on the belt turned from red to yellow. The visor disappeared and the armor rearranged itself. The backside armor soon switched to the front and red to the back. Just then an axe with yellow sides slid down the silver line on the helmet. Soon the yellow pieces opened up and went down to the eyes, becoming the new visor. This is Kamen Rider Den-O Axe Form.

"Ore no tsuyosa ni… omae ga naita!" Den-O AF announced, with Kintaros' voice and cracked his neck.

"Don't do that so suddenly you dumbass bear!" Momotaros exclaimed.

"Sorry for suddenly possessing you." Den-O AF apologized.

"It's okay. Let's just beat them and go to class." Jikan said.

"Hai!" Den-O AF said before fighting. He slashed two of the Mole Imagins just as ruthlessly as Momotaros with the DenGasher, shaped like an axe, before he picked one of the Mole Imagins up by the foot and threw him torwards the other two.

He then dived into the pile of three Mole Imagins and began fighting them as if he was wrestling them before he grabbed one of them and slashed him.

"Kuma-chan! I want to play too!" Ryutaros said in an excited tone.

"No wait! Ryuta-!" Den-O AF was interupted when Ryutaros possessed him.

"GUN FORM!"

The yellow armor went back to its original position but the red chest plate folded out and turned inside out before being attached on. Just then the axe visor disappeared leaving room for a new one. Just then the head of a purple Chinese dragon appeared down the railing of the helmet before parts of it unfolded turning it into a V shape visor. This is Kamen Rider Den-O Gun Form.

"Omae taosukeba ii wo ne?" Den-O GF asked, with Ryuutaros' voice, as he did a little dance jig before spinning around once and then pointing his hand at the Mole Imagins like a gun. "Kotae wa kiitanai!"

"Don't get cocky!" Den-O GF turned to see a Rabbit Imagin coming his way.

"I'm guessing those bullies from Class-D wanted to get back at me for when you guys met me." Jikan said.

"I'm still surprised that you look exactly like a younger Ryotaro." Kintaros commented before Den-O GF formed the DenGasher into a gun and shot two of the Mole Imagins.

He dodged the Mole Imagins, who maged to reach him, in a dancing manner before shooting at them with bullets. He jumped on one of the Rabbit Imagin and started spinning around while shooting at the same time. He jumped off and shot the Rabbit Imagin before he effortlessly shot all the Mole Imagins.

"You guys are really annoying." Just then Urataros spoke up.

"Ok then, switch!" Urataros jumped into Den-O, ejecting Ryutaros out.

"ROD FORM!"

Den-O changed again and this time the red armor parts went back to the rear, the yellow pieces spilt apart and became shoulder pads, and a blue chest plate was left on. The Gun visor disappeared and a blue turtle with orange lenses took its place. The head and legs folded while the arms are moved upwards forming the new visor. This is Kamen Rider Den-O Rod Form.

He rearranged the DenGasher in the form of a staff and laid it on his shoulder.

"Omae, boku ni tsurarete miru?" Den-O RF said in Urataros' voice.

The Mole Imagins charged at him, but Den-O RF simply either dodged their attacks or blocked their attempts. He slashed two of the Mole Imagins simply before blocking the third ones axe hand and slashed him. He then threw his DenGasher like a javelin at the Rabbit Imagin, he rushed to the him and pulled the DenGasher out of him then kicked him away before swipping his pass over his belt.

"FULL CHARGE!"

Blue electricity went to the tip of the DenGasher before Den-O RF swung his rod and blue energy balls went towards the Mole Imagins and they exploded on contact, leaving the Rabbit Imagin left.

"Don't hog my climax!" Momotaros then jumped into Den-O.

"SWORD FORM!"

Den-O quickly went back into his Sword Form as Urataros landed to the side.

"Sempai!" Urataros cried out.

Den-O SF looked at the Rabbit Imagin while transforming the staff back into a sword.

"You bastard!" the Rabbit Imagin growled before charging

"Now to take my climax!" Den-O SF announced as he got his pass and placed it in front of his belt.

"FULL CHARGE!"

Red energy flowed from it and into the sword. The blade then flew out of and floated in the air.

"Hissatsu! Ore no hissatsu waza! Part 2!" Den-O SF then swung the bladeless sword towards the Rabbit Imagin. The floating red blade followed its arc and put a large cut onto the little yellow machine. He did it one more time before doing an overhead slash destroying the monster. And with that the Imagin exploded.

Den-O SF took off his belt, which turned him back to Jikan, with Momotaros going back to DenLiner.

"Alright. We won!" Jikan cheered with a fist pump before…

"Top of the morning to you Mr. Nogami!"

Jikan's jaw comically dropped and he slowly turns around to see…

"G-Good morning Koro-Sensei." Jikan nervously said to his octopus teacher.

"I went to look for you because you never came to class on time, but I saw that fight earlier. And I must say I'm impressed!" Koro-Sensei said as the red circle appears on his skin.

"Well uh… that's an audition for a new TV show!" Jikan said and he hopes that he'll believe it.

"Well if you need proof then don't worry because I recorded the entire fight at Mach 20 speed at different angles!" Koro-Sensei said as he showed a video of the fight on an IPad, which he took out of nowhere.

"Aw come on!" Jikan said before Momotaros took over his body.

"You've been filming the entire thing!?" M-Jikan exclaimed.

"Why yes I did!" Koro-Sensei nodded as if it's no big deal.

"Teme, Tako-Sensei!" M-Jikan took out his anti-sensei knife and made attempts to slash him, but as usual, the teacher dodges at Mach speed.

"I expect an explanation when we get to class." Koro-Sensei said. "Also, I just e-mailed the video to your classmates."

"SERIOUSLY!?" M-Jikan yelled while Jikan yelled in his mind comically.


Two black hooded figures watched the whole thing and they seemed interested.

"Wow. Dark Decade wasn't kidding when he said that teacher is an octopus that can move at Mach 20." one of them mused.

"So this world that he sent us to is Den-O's? But not just an AR Den-O but OUR Den-O. I feel that this is our lucky day." the second one said with the other nodding in agreement.

"Indeed, finally we may be able to have our revenge. But it will have to wait. Let's go, Yuuki." the first one stated before walking away.

"Right behind you…Gaoh. I can't wait to see the look on Negataros's face when he hears this."


Done! I hope you enjoyed the Assassination Den-O trailer! Oh and for those who are wondering who Jikan is, think of him as an AR version of Ryotaro Nogami since he's just as unlucky as he is.
