Location: Winter Bluffs

Date: October 6th, 2021

It cuts to a youth in school, wearing typical Japanese school-boy attire. He had black hair with purple at the roots, and deep green eyes. This was Kamui Takigawa, a young man on the autism spectrum.

"Mr. Takigawa?" said the teacher, catching the boy's attention "Could you please tell us who the first black samurai was?"

"The first black samurai was an African man who was given the name 'Yasuke'." said Kamui, sounding like Nobuaki Kanazawa from King's Game "He arrived as a slave of the Itallian Jesuit missionary Alessandro Valignano. He was one of several Africans come to Japan, during the nanban trade, and the first African that Nobunaga saw."

"Correct." said the teacher, taking note of the young man. Kamui sat back down, reading some manga he checked out

Kamui's POV

"My name's Kamui. Kamui Takigawa. I'm an autistic college student living with my older brother and sister ever since the deaths of our parents. I live a somewhat normal life with my friends and family, but...what I didn't know, was that something big was heading this way, and my life was about to change forever in more ways than one."

Chapter 1: The Beginning

It cuts to Kamui at the local community center, training for an MMA match, so he can use the prize money to save the community center from being destroyed. He was landing blow after blow on a speedbag, wearing a tanktop, shorts, and sandals.

"You can do it, Kamui!" said Taiga, one of Kamui's friends, cheering for Kamui, as he was busy training

"Kick some asses!" said Kasumi, a friend of Kamui who secretly harbored feelings for him. Kamui kept punching away, and he decided to lay down for a bit

"Phew." said Kamui, wiping some sweat off of his brow, as he took a swig of Powerade "That was an intense workout session."

Meanwhile, an alien spaceship was entering Earth's orbit. It resembled the Crisis Fortress from KR Black crossed with the Free Joker from Goukaiger. This was the Nightmare Fortress, owned by a race of aliens known as the Giganoidians. The Giganoidians were composed of the warlord, Giganidas, the swordsman, Zankrod, the general, Meverak, the assassin, Kamdor, and the jester, Girax.

Giganidas looked like N-Daguva-Zeba from Kamen Rider Kuuga, but his head was a hybridization between Overlord Inves Baron from Kamen Rider Gaim and Darrgon from Ultraman Trigger. He had the forearms of Monster Form Basco ta Jorokia from Gokaiger, and the face of Perfect Cell from DBZ, the horns of Vasto Lorde Ichigo Kurosaki, the dreadlocks of a Yautja from AVP on the back and sides of his head, and the wings of Goldar from MMPR. His skin was dark green with gold accents and his eyes were blood red with purple sclera and slitted pupils.

Zankord looked like DeluKnight from Akibaranger, with the head of Kamdor from Operation Overdrive, with an open faceplate revealing a face similar to Overlord Inves Baron.

Meverak resembled Damaras from Goukaiger crossed with General Schwarz from Toqger and Wreckmate from Power Rangers Dino Fury

Kamdor resembled a sci-fi version of Deathstroke from Injustice: Gods Among Us

Girax resembled Reala from the NiGHTS games franchise crossed with Laughing Jack from Creepypasta.

"Report, Girax." said Giganidas, sounding like Baron Draxum from Season One of Rise Of The Teenage Mutant Ninja Turtles

(Author's Note: Giganidas' voice actor is John Cena, a former professional wrestler and actor.)

"Looks like we're in Earth's orbit as we speak, milord." said Girax, aknowledging his master.

"Excellent." said Meverak, wringing his hands together "Soon, that insignificant ball of dirt will be under the control of the Giganoidian army!"

"Now, which Darkmare shall we send to terrorize the populace of Earth?" said Zankord.

"How about..." said Girax, as he used his Monster Gene Splicer to combine genes from an Aracnea Worm and the Mole Amazons in it's Evolved Form. The next thing anyone knew, a monster that resembled a fusion between the two emerged.

"Introducing, Mogurachnid!" said Girax, revealing the monster to his fellow villains.

"At your service, milord." said Mogurachnid, kneeling before Giganidas and his forces.

"Mogurachnid, I want you to go down to Earth, and cause some havoc amongst the Humans." said Giganidas. With that, Mogurachnid was beamed down to Earth, and started to attack people left and right. Meanwhile, a scientist was holding a box.

"I need to find someone with a caring heart who can stop these monsters." said the scientist. As he raced to find someone.

Later, Kamui was later seen exiting the youth center with his friends, and was hanging out at the local smoothie shop, just relaxing.

"Man, this is life." said Kamui "I mean, my brother is working as a security guard, and my sister is an E-Sports FPS master."

"Cool." said Kasumi, suddenly, they noticed a group of people running, and they saw why. Mogurachnid was causing a panic amongst the people. Kamui felt a little scared, and he and his friends made a run for it.

Later, Kamui ran into the scientist.

"Kamui Takigawa." said the scientist, facing Kamui "I've been looking for you."

"Who are you, and how the hell do you know my name?" said Kamui, curious on who the man was.

"My name is Dr. Charles Anderson, I'm a multiverse researcher who believes that good should always triumph over evil." said the scientist. Kamui noticed that the scientist's side was bleeding.

"Sir, you're hurt!" said Kamui, facing Dr. Anderson with a concerned expression on his face.

"Kamui..." said Dr. Anderson "You must become the hero that the Multiverse is looking for. You must become...Kamen Rider Millennium."

"Me...?" said Kamui, surprised to hear this news.

"The Giganoidians are planning on controlling the Multiverse, one world at a time." said Dr. Anderson "It's up to you to stop them."

"If it's to save our world and others like it from complete and utter destruction...I'll do it." said Kamui, determined to save the world from evil.

The next thing anyone knew, Mogurachnid arrived, chuckling darkly.

"So, the goody-two-shoes doctor chose a mere child to protect the Multiverse?" said the monster "I'd like to see you try!"

"I'll do more than that, asshole!" said Kamui, as he opened the box, revealing a belt similar to the DecaDriver, but colored white, gold, and silver, with the emblems for various Riders from Showa, to Heisei, and then Reiwa. With that, Kamui slapped on the belt, causing the straps to appear

[MILLENNIUM DRIVER!]

Kamui then took out a card with an image of a Rider's helmet on it.

"Henshin!" said Kamui, as he inserted the card into the belt

[KAMENRIDE: MILLENNIUM!]

With that, Kamui was clad in white, gold and silver armor with a barcode motif. He looked like Decade, but was colored white, gold, and silver. He had cyan colored optics, too. He had a weapon similar to a Drive-Defender from Power Rangers Operation Overdrive holstered onto his belt.

"What!?" Mogurachnid gawked, backing away in shock "How is this possible!?"

"What's possible is possible, pally." said the transformed Kamui "I'm Kamen Rider Millennium, and I'm here to stop you!"

"God damn you...!" growled Mogurachnid, until "ZOMBORGS!" the monster bellowed, as a squadron of grunts arrived. They resembled X-Borgs from PR Super Megaforce crossed with the Battle Magia from KR Zero-One. Millennium then took the weapon on his belt, and converted it from gun mode to sword mode, and started slashing away with it. He then converted the weapon back into gun configuration, and shot at the lesser monsters. Mogurachnid got angry, and fought Millennium, who punched, kicked, and slashed at him. Mogurachnid was getting weakened with every attack.

"Who...who the Hell do you think you are!?" said Mogurachnid

"In the words of Tsukasa Kadoya, AKA Kamen Rider Decade: "I'm just a passing-through Kamen Rider. Remember that." said Millennium, as he inserted another card into his belt

[FINAL ATTACKRIDE: MI-MI-MI-MILLENNIUM!]

With that, energy constructs of cards appeared, with Mogurachnid being caught in between them.

"The bloody Hell!?" said Mogurachnid "I...I can't move!"

With that, Millennium then jumped into the air, and did his own variation of Decade's Dimension Kick, which was a flying kick, and once the attack connected, it was a permenant job.

"DAMN IT AAAAAAAAAAAAAALLLLLLLLLLLLLLL!" Mogurachnid bellowed, before he exploded. Millennium then raced to his friends

"Did you guys see that?!" said Millennium, with an excited expression on his face "I kicked that monster's ass!"

"Yeah, you did, Kamui." said Taiga, smiling a little. Millennium then took out another card on his holder, and inserted it into the MillenniumDriver

[ATTACKRIDE: MILLENNIUMLINER!]

With that, a futuristic bullet-train with a KR-Decade esque motif appeared from a dimensional vortex, and it came to a stop. The door slid open to reveal a robot similar to Alpha-7, but different.

"Hello there, everyone!" said the robot "I am Alpha-10, the cybernetic assistant to Dr. Anderson."

"Hello there, Alpha." said Kamui, as he and his friends walked inside of the MillenniumLiner. Dr. Anderson then faced the teenagers

"I leave the rest to you guys." said Dr. Anderson, as a portal opened "I will return to my home dimension for medical treatment."

With that, he went through the portal, and dissappeared.

"Looks like our first stop is the world of Rosario+Vampire." said Kamui, as he walked into a room containing a motorcycle similar to the Machine Decader, but in his style. And just like that, the MillenniumLiner went through a dimensional portal
