Chapter One
It was the year 2009; Kamen Rider Decade had been awakened by Kiva, Kurenai Wataru. Across the Rider Universe, the once strong pillars holding the individual worlds together have become brittle and are crumbling. In the Kabuto world, a rider was fighting off worms when the ground shook and a seam opened up from thin air. The worms jumped into the seam in an attempt to escape the constant onslaught of attacks produced. However, the rider was too stubborn and chased after them, entering the seam before it closed.
Two weeks after the earthquake that shook, time seemed to go on as per normal. It was late at night on dark alleyway; Nogami Ryoutarou was cycling without a care on his way home, until he was attacked by worm-like beings. At first, they were the usual human beings just passing by. However, Ryoutarou found them rather odd and took a second look which made them transform into humanoid worms. They were dark green and truly a horrendous sight to behold. To Ryoutarou, it seemed like a dream. However, they were worst than the imagins he fought all along.
"What are those things?" He said as the four advanced towards him and got off his bicycle.
'Ryoutarou let me handle them!' Momotaros assured him and entered his body.
"Ore sanjou!" Momotaros declared as he used Ryoutarou's body to fight them.
He punched and kicked but they still kept on coming. It is like fighting something unstoppable, something that is dead.
'What should we do, Momotaros?' Ryoutarou asked as they fully surrounded them, their back against the wall.
Momotaros gritted his teeth and answered uncertain of what to do,
"Like I know!"
"Kameko (Urataros) is flirting with Naomi. That brat (Ryuutaros) will not take anything seriously unless it has to do with nee-chan and Kuma (Kintaros) is still sleeping back in the Denliner!"
They were in dire need of help and even though they can transform into Den-O. It was the fact that they were human, made Ryoutarou reluctant to fight them, putting Momotaros at a disadvantage.
Then, a rider wearing weird robotic armour on a motorbike was heading their way.
"What is that?" Momotaros asked, looking confused.
The Rider jumped off and landed next to them.
"When I give you an opening, get away as fast as you can." The rider whispered to him.
It was clearly a girl's voice and she was a head shorter from the nineteen year old Ryoutarou which made it very clear that she was younger than him. However, Momotaros kicked her back which made her fall onto the hard paved floor.
"What are you saying, you brat!" He shouted out in anger.
'Momotaros, what are you doing?' Ryoutarou asked.
She got up and the worms took a step back.
"I know what I am doing." She replied confidently
"No matter the risk…" and she took out her bow attached to her back which looked like wings.
The rider had an aura. This aura has a rather arrogant and yet a hidden kind intention. Her hand fanned out open and static begin to form upon her finger tips. When she placed her fingers on the bow, four arrows made out of lighting formed. As the rider braced her bow, the insects dispersed in all directions, attempting to escape the rider's attack. She aimed and released the four arrows at once.
"Chase!" The rider exclaimed as recomposed herself to her full height.
And the four arrows pursued their targets relentlessly and destroyed them.
Momotaros and Ryoutarou were in awe as the rider turned and walked off towards the direction of her bike.
"Wait!" M-Ryoutarou said as she mounted on.
She looked at him and her insect like mechanism that was the source of her transformation flew from the transformation belt and into her pocket. She had beyond average human abilities and yet she was covered in cuts, bruises and blood. Her bracing arm (Left arm) had two deep gashes.
'Blood…' Ryoutarou whispered as she looked at them.
The rider started her engine and was about to drive off until she collapsed off her motorbike, onto the ground.
'Momotaros, we have to help her!' Ryoutarou exclaimed.
"Help her? Exactly how are we going to help her?" He replied
'Probably we can bring her aboard the Denliner and treat her there.'
Momotaros gave a puzzled look in reply to the comment that Ryoutarou made and yelled.
"How can we bring her on the Denliner? She's not a singularity point like you in the first place!" he replied as he walked towards the rider.
'I don't know but we can at least try right?' Ryoutarou asked him.
M-Ryoutarou piggybacked the girl, mounted on her bike and rode off towards the nearest door as the time for the time train's usual stop was approaching.
The time was 20.20.20. This was where the Kamen Rider of this world was returning the favour to a Kamen Rider of another. This time was the starting of many other adventures.
