Tamashii Souto was your ordinary teen. That was until the events with the megahex. After a near fatal wound taken trying to help the heroes and their temporary allies he finds a dropped viral core and somehow fuses to a roimude created by the megahex. Taking the sengoku driver from the statue of Kamen rider baron and finding a way into helheim he gets a lockseed and arrives at yokai academy. The roimude will have to learn what it means to be a hero when it is revealed someone had taken the remains of the battle and plans on using them to destroy the monster world. "It's time for a rampage!"
Pain that was all a young teen could feel as he struggled to stand. It had all started when mechanical beings known only as megahex appeared seemingly having killed one of the famous Kamen riders. He was able to escape the strange transformation that mechanized part of the city but the rest of his family wasn't as lucky. Turned to data and killed by the strange event. When Ryugen destroyed the two kurokage copies the teen had grabbed the only remain intact of the two besides the sengoku driver from the wreckage a indicator that once was filled with a image of a specialize helmet was now blank. Soon though the megahex returned and Ryugen now aided by his brother zengetsu fought the megahex who had revived a old foe of the riders. Sengoku ryouma the creator of the driver.
Then came the revival of gaim and where the teen himself joined the fray gripping a kurokage Lance he grabbed also from the wreckage to help them fight the megahex only for more of the android to appear and reveal that they were just constructs the real megahex was actually the planet they came from itself. Then they androids scattered.
It returned with a new look and came the emergence of a new rider by the name of drive when the megahex had revived a dead rider. Kumon Kaito aka Kamen rider baron. He turned against the megahex and gaim and drive fought against the main unit while the rest joined by three strange characters fought the materialized enemies of invess and roimude as the three allies identified themselves.
During the battle the teen took a fatal wound with a claw destroying a lung and nicked a hole in to the heart. This stopped the heroes in shock that the teen was still alive.
With his weapon he destroyed the foe and was left on the ground when it seemed the foes and baron shut down signaling that gaim and drive did it. Now the teen struggled to stand as the sengoku riders in their celebration forgot the teen only for the one known as chaser to walk by with his two allies and the one known as heart dropped something resembling a silver toy car with a design like a skull right into the teens hand by accident. Once everyone but the teen with blood going out of his mouth and the large wound in his side manage to use his staff to stand and stumble by the baron statue his free hand accidently snagging on the driver and pulled it off with the banana lockseed shattering from the fight and the indicator fell off as the teen struggled to walk before tripping dropping the spear, driver, and blank indicator.
The silver car he gripped glowed as his fall collided his body into a human type roimude statue. Suddenly the teen felt a curious sensation as if his pain was vanishing like water flowing off him. When he stood he found himself healed as he note the roimude had vanished.
"That was weird" said the teen before looking to see he had dropped some items and picked them up.
The spear suddenly was covered in some energy becoming a metal band with a charm of the weapon dangling from the non blade end on a small three to five inch chain. The sengoku driver he picked up and seeing the indicator fit the missing space snapped it onto place and started to move off confused.
Suddenly he felt a ripple under him and looking down found what seemed to be a forest below him. With a yelp the teen fell and landed in the Forrest floor confused as the rift now that he got a good look resembled a zipper closed.
Before him was a face he recognized from the beat rider hot line stresm.
"Sagawara" said the teen confused at the man now in what looked like traveling garb.
"Seems you have been through a rough ordeal. Seems your confused at what happened allow me to explain what happened to you" said Sagawara pulling the teen to his feet.
"I will be frank kid your no longer human but a android. A roimude like those three that helped you and the riders today. What heart the red one dropped was basically their means to revive. A core they can upload their mind into called a viral core. When you collided with that core less roimude copy you were fused with it saving your life. It was reckless of you to join the fight they had it well in hand. This puts you in a odd situation. You have nothing left in our world. Your family killed by the megahex and fought and managed to avenge them but now you got nothing to tie you to our world besides being a roimude.i see you grabbed the driver so at least your prepared just in case. Here I been holding onto this just in case" said Sagawara handing the shocked teen a lockseed but unlike normal lockseeds this one was black instead of silver with the black arm and switch on the side being silver. On the front was a fruit that resembled a mechanical blackberry.
"This is a oddity among lockseeds being inversed in color and if you want I can send you someplace to Start over if you wish. What do you say kid might be worth your while" said Sagawara and the teen looked at his new lockseed and then picked up the driver.
"A new life sounds good but before I head over to the new world I need to learn how to properly use my new body" said the teen.
"That much I can help with so what is your name kid I forgot to ask" said Sagawara sheepishly.
"As a human I was Souto Tamashii but now I'm soul as a roimude. I'll keep souto in the name to remind me I still have my humanity" said the now named soul putting on the driver and the indicator chimed as a image formed. It resembled a silver helmet that was styled like a ninja with a gear acting as a crest with the visor having a rainbow multicolored look. Placing the lockseed on the hook clipped to his belt loop the teen looked to Sagawara.
"A good name fits you so now let's get you used to your roimude form soul you have much to learn about your new abilities" said Sagawara with a nod.
With that it would be a month since soul would arrive to his new home and already got two new lockseeds to add to his arsenal. One was a itchigo lockseed the other was kurokage's pinecone lockseed. With a nod to the man who helped him learn to use his abilities he entered the Crack that was opened and found himself in what looked like the outskirts of a forest. The welcome to sign read yokai academy. Walking in the teen found himself staring at the castle like building that was the local school.
"Yokai academy? Guess I'm in a world where monsters exist somewhat well better enroll and find a place to live" said soul walking in.
