Well then here it is once more time let's look at the meeting between Hino Eiji and Tachibana Hibiki, Kazanari Tsubasa, Amou Kanade!

Prologue: New World! Multi-King and the Songstresses!

This place that look like a battlefield was actually a concert hall that is until a few minutes ago when a bunch of monster that, people in this world was so used to call as Noise, have appear and trash this place to dust.

It is unclear where they from or why they are here except the fact they bring destruction with them everywhere they go, every weapons that human known and used to take proud of have no effect on these creatures as everything they touch is turned to dust.

But unknown to everyone the govt. have one kind of weapon that can kill the Noise, relic that have mystical power which choose it user and give them armor with weapon that can affect the Noise. The govt. call these Relic, Symphogear. And currently in this place there are two person with Symphogear who are fighting against the Noise.

They are Amou Kanade and Kazanari Tsubasa. While to everyone they are known as a famous pair of idol Zwei Wing. They have fight the Noise for almost years now but this time is proven to be most difficult as the number is way higher than what they have face before, they try to slash away all the Noise with their spear and sword respectively but the number still too much.

As Kanade was struggling as a bunch of Noise she notice that there is one person who hasn't run from the Noise yet. A girl about 13 or 14 years old her name is Tachinbana Hibiki.

Kanade (Gungnir): "Hey! What are you doing!? Hurry up and run!" Call out as she quickly push back the Noises to gain the chance and dash toward the young girl who still stubbed by what she is seeing.

Hibiki: "Huh? Uhm yes I got it!"

As if just got out of a trance she ready to run when she found herself was surrounded by the Noise. Kanade rush to her as fast as she can and slash away few of the Noise, some of them twist themselves to become an arrow and head straight to her while some other spit out green poison, she used her spear and spin it around as a shield to protect herself and Hibiki who is behind her and have a wounded leg which made her unmovable which forced Kanade to stand there while use her spear to block all the fire power coming from the Noise, but then her armor suddenly feel heavier to her why Kanade herself feel that her spear is getting weaker.

Kanade (Gungnir): "(Tch) is the suit power already reaching reach its limit." Cursed under her breath as she still try to fend off all the attacks. Eventually her weapon and armor can't handle the stress anymore as they start to crack and get blow off from the attack with one of the fragment hitting against the young girl heart and slam her to the wall nearby with blood flow out from the wound.

Shocked Kanade rushed to her side right away just about time the Noise stop their ongoing assault but they also slowly start to approach Kanade.

Kanade Gungnir): "Hey! Don't die, open your eyes please."

Hibiki let out a few cough indicate that she is still alive, making Kanade let out a relieved sigh before her expression hardened again as she ascertain the surrounding once more.

Kanade (Gungnir): "She is still alive but the wound need to be treated right away. And this amount of Noises...Heh...I guess this is it eh?" Thought with a resigned smile formed on her lips.

She pick up her spear and point it toward the where the Noise gather and begin to sing the song that will eat away her life. Tsubasa from afar also holding back multiple Noises seeing this let out a gasp.

Tsubasa (Ame no Habakiri): "No! Stop it Kanade don't sing that song please."

As Tsubasa try to get to Kanade side she is surrounded by bunch of Noise and try to slash all of them away with her sword but the number still not decrease much as she hoplessly witness her friend ready to throw her life away to destroy the Noise and have already start to sing her Swan Song, she heard a sound, as she look back to this day, Tsubasa will always remember that sound.

SCANNING CHARGE

After that the swipe through the battlefield was a giant phoenix made of flame and it wipe off all the Noise, it presence also stopped Kanade from finish her Swan Song but she still collapse and cough out blood Tsubasa rush to her side right away after the Noise around her was also destroyed by this flame phoenix. At that time not just Tsubasa and Kanade but the semi-conscious Tachibana was also staring as the phoenix that just seemingly helped them in awe as it descend to the ground after all the Noise was destroyed the phoenix disappear revealed an armored figure with a belt that have three red coins in it.

Tsubasa: "who…. Who are you?"

?: "I'm OOO. Kamen rider OOO."

That sound...is a signal that announce to this world the coming of the Multi-King.

At the universe of Neo-Heisei Riders, in space.

Right now, there is a battle that determine the fate of the planet, on the riders side there are OOO, Hino Eiji, and Fourze, Kisaragi Gentaro, while their enemy is Lem Kannari who have obtained the power of Cosmic energy and Medals of Desire.

Both riders OOO in his Super Tatoba form and Fourze in his Double Rocket form is ready to launch their Rider Kick.

OOO Driver: "SCANNING CHARGE!"

Fourze Driver: "LIMIT BREAK!"

OOO & Fourze: "Rider Double Space Drill Kick!"

Gentaro (Fourze-Rocket State): "Yahhhh!"

Eiji (OOO-Super Tatoba): "Seiyahhh!"

The two Kamen Rider rush toward the Galaxy King with their own special attack and collies at the mad scientist.

Kannari (Galaxy King): "How!?...How could I... someone who... suppose to be the new King of this whole galaxy... be defeated by bunch... of ...Kamen Rider like you guys?" This were his final word as he get blow away by the force of the attack even faster then the rocket they are on but the rocket catch up with him as it hit him and explode in the process.

With Kannari destroyed after he received the attack from both rider, Gentarou also known as Fourze finally released the Soluu energy in the form of Nadeshiko and she said goodbye to him after she give him a kiss. Meanwhile Hino Eiji in his Tajadoh form now notice that the same black hole that Poseidon and Ankh came from have opened again from the explosion of Kannari. Fourze notice something strange from OOO and ask

Gentarou (Fourze-Base State): "Eiji-san is everything alright?" While OOO after a second of silence finally reply

Eiji (OOO -Tajadoh): "Gentarou-kun could I ask you a favor?"

Gentaro (Fourze-Base State): "Eh? Sure. What is it Eiji-san?"

Eiji (OOO-Tajadoh): "Right now...in that portal, there might be a chance for me to reach a dear friend of my. Maybe it will be a failure in the end..." Said as his voice hardened. "Even so, if there is a chance for me to find him, I must take this chance." As this he turn toward Fourze. "So I hope you can tell my friend back at Earth they don't need to worry as I will return soon."

Meanwhile Fourze just look at him before a wide smile appear behind his armor.

Gentaro (Fourze-Base State): "Sure! Friend is people who are most important to you! Don't worry Eiji-san, I will help you. Is the least I can do, too bad I can't help you since the Zodiart still a threat to my school." Said as he lowered his head in shame but OOO just pat on his shoulder in grateful.

Eiji (OOO-Tajadoh): "Arigato Gentaro-kun, this is the best you could do for me already. I wish you good luck on your school year and your battle a head. Well then I will see you later." Said as this time he the one who give out his hand first as Fourze just look a bit surprise for a moment before he grin and nodded as he does his signature handshake with OOO.

And just like that OOO take off in his quest to find the lost Greeed, Ankh and unknowingly will get drawing to another conflict from another world. And with some problem that mostly involve female too of course, so let's hope he has enough underwear he need.

Meanwhile in what one could describe as a space between dimension, the Galaxy King just defeated by OOO and Fourze can be seen with only his upper body while his lower body along with his limps are destroyed. But for some reason even with this mutilated body, there is still movement seem to come from this body. Did the Galaxy King manage to survive both OOO and Fourze final attacks?

No. At that time both Riders had put their strongest powers for one finishing attacks, the powers behind it was enough to vanquish any life there is in the former human. Yet this movement come from something else that was also inside the Galaxy King. For it was not only Nadeshiko who was trapped inside Kannari but still retain her consciousness. There was another existence who despite received a combination attack from both OOO and Aqua but still manage to survive. But because of the state he was in, he was unable to resist as Kannari freely draw out his powers but now with the hateful human dead nothing could stop this existence from broking free and reclaim what is his anymore.

An armored gauntlet burst out from inside of the dead man chest, another hand shot out and rip apart his body before it slowly form itself again in a darkness before it shift to a blue light with three familiar Medals revolve around it. It slowly become a small vortex before a figure can be seen inside it.

"Hm...To dare and use my power like that, death is too good for you Kannari." Said as it absorb the darkness that was the Galaxy King just a second before. "Galaxy King eh? At least your power in the end give me a great help to recover faster. For compensation I will be taking it then." Said as the armored figure finish absorb the energy. Result in two yellow eyes flare up in power. "Incredible, this power was never unleash it true potential because someone like Kannari hold it. " Said as the figure clench his fist before he use his new enhanced sense to find someone who he can tell is also near. "Now then...to finish what I started." Said as the figure suddenly radiate with power as his eyes flash with golden light.

Eiji (OOO -Tajadoh): "I can sense it...Ank's Medal." Murmured as his eyes now flash in purple as he is utilizing the power of the only set of Medals that are the most dangerous to him but as the same time the set that truly belong to him. In truth, the purple Medals were never destroyed. To be more precise they were meant to be asleep forever in his body since their powers are basically gone after he defeat Maki. Since unlike other Medals, the Purple Medals had bone with him way above the level of separate existence already, even if he never use it, even if it lose all its power. The Medals still exist in him. It merged and represent his hollow desire for power to reach out for other. That's why when he gain back the other Medals once more, these Medals also awakened. But of course due to its nature it take longer than other to stabilize, thankfully right now is that moment so with that OOO manage to track down the Medals belong to his friend. After a while wonder through a dimension space, that OOO can't help but wonder if this is just like how Tsukasa aka Decade see sometimes when he travel through the world, he has finally reach the location he looking for.

OOO chuckle to himself wonder how Anhk would react to this probably, no definetly he would call Eiji an idiot again and in order to hear those word he would need to go to where Ankh is and found out how to fix his Medals.

When OOO had finally landed he wonder if it is one of the power of Medals now after travel through space and time but he able to known one thing right away. This is not the future, this is a different world and not one of those alien or something but another Earth in different dimension like how he heard from Decade in the event with Den O and Shocker with Medals power.

Even though this is a different world he still able to sense Ankh intact, could it be Ankh also accidentally drop to this world at least he could still find him here then. But before he can think of anything else he notice that wherever he is the people here is in trouble. In front of him is a battlefield with a kind of monster that he never see before not even any other rider's enemies is similar to these.

But more importantly he noticed a girl in red hair and a girl in blue hair is fighting against those monster, he also notice a girl with orange hair is wounded and she need help, moreover is seem like a girl with red hair is ready to throw her life away to save the kid even if it mean to waste her life.

He can feel it in her because it just like when Ankh ready to use his last power to save him before disappear. Not waiting anymore moment he take out his scanner and scan it across his belt.

From now on this world will not only have Symphogear as the weapon that can fight Noise it will also include... Kamen Riders.
