At night in the boiling isle's.
Apollo was in His room, he put a posters of kame riders Ryuki, he was now sitting on his bed with a box and he opens it, it has the all of the kamen rider decks from Ryuki including even Abyss deck along with Alternative and Zero, on the top of the lid is the buckle with the Alternative decks next to it, he was happy to have them since he was a huge fan of Ryuki so having them along with the Alternative decks made him so happy.
"I'm glad to have these and good thing I got this box that can hold them all."Apollo said and then he closes it.
Apollo then sees a shooting star and made a wish:"I wish I can be a Kamen Riders."then it twinkled and he was covered in a blinding light.
Apollo opened his eyes to see he was in a alley with his box next to him and a duffle bag with clothes in it and he said:"where am I?" he then notices a note and picks it up and reads it:"dear Apollo, you wish is granted now you have a chance to be a kamen rider in this world, you have access to all of the decks along with the Advent Beasts but don't worry they won't be needing food since their more docile in comparison but have their own will, along with mirror world not being harmful so good luck."Apollo was in shock, he has the Advent Beasts that are now more like Dragon Knight and he has Mirror World.
He then notices a broken mirror and when he looked at it he saw all of the Advent beast's looking at him, he then picks up the box and back pack and jumps in, when he entered mirror world he saw all the beast's looking at him, they nodded and made noises to tell him that he was welcomed, Apollo was so happy and he got excited.
then one of the Gigazelle approach him and gave him a card, he takes it and it said Shuffle vent with the image being the rider symbols spinning around and the symbol on the corner has all of them except Alternative."Shuffle vent I guess it means I can swap the deck in the middle of a figtht, well thanks you guys." Apollo said and the beasts roared in happiness.
Then they heard a sound and Apollo runs to another part with the beasts following him, when he arrived at a garden and noticed the Eiffel Tower and said:"okay I'm in Paris,he then looks to a window and saw a guy wearing a top hat with a moon on it and a suit and his face was pale.
He was next to the tower and said:"Now I the great Magician of Misfortune shall make the Eiffel Tower disappear."
"Not today."Apollo said, he then opens the box, the belt was gone and he takes out Ryuki's Advent deck, he could feel the weight and the material, it was different now, he points it at the reflection and then the buckle appeared and went to his waist."Henshin."then slots the deck in the buckle, then three reflections came to him and formed the suit transforming him into Kamen Rider Ryuki.
When the Magician of Misfortune was about to make the tower to vanish with a wand he then heard a voice:"hey magic man."he turns back to see Ryuki jump to the air and land in front of him.
"Who are you, your not Ladybug or Cat noir?"Magician asked confused seeing him.
On the other side of the garden was a little girl watching it, she has messy dark brown hair pulled back into two ponytails, golden-brown eyes, and two upper front buck teeth, she was amazed at seeing the new hero.
"Manon."she looks to her right to see Alya who goes up to her."it's dangerous to be near the supervillains, if your mom finds out Marinette will be in trouble."
"But theres a new hero."Manon said.
"Wait, what?"Alya said surprised and sees Ryuki."Oh my gosh, a new superhero."she then takes out her phone to film the fight.
"I am Kamen Rider Ryuki."Ryuki said while doing a pose, he didn't know who Ladybug or Cat noir are they must be the heroes of this city.
"Ryuki, well not matter it seems before I do my most amazing act I must take you out."Magician said.
"Oh yeah."Ryuki said and then he charges at him.
Magician uses his wand to make chains to appear and sends them at Ryuki, Ryuki stopped to see them and rolls to the side to avoid them but they came back.
"Let's kick it up a notch."Ryuki said then he takes out a card for Sword vent, he opens the Drag visor and places the card inside and closes it.
SWORD VENT
Then a sword came from the sky and Ryuki grabs it, it was the Drag Saber and Ryuki cuts down the chains making them vanish surprising the magician, Ryuki then goes after him and engages him in close combat using the sword only to counter his magic, Ryuki throws a couple of punches at Magician who was able to dodge a few but then Ryuki does a spin kick sending him to the ground.
Magician got up and said:"I will not allow you to ruin my show."he then uses his wand and makes multiple knifes appear around Ryuki.
"Woah."Ryuki said then he takes out another card and puts on the visor.
GUARD VENT
His shield appears on his arms and he used them to block the knifes as they rained down at him, when they stopped Ryuki got up and he was fine.
"Nice try, now magic man I'm going to my own magic act, I will make a dragon appear."Ryuki said.
"What?"Magician said confused.
Ryuki takes out a card for Advent and puts it on the visor.
ADVENT
A mirror like portal appear next to Ryuki and then came Dragreder roaring surprising everyone, it then hit Magician sending him away and knocking him on the floor.
"He has a dragon, that's so cool."Manon said excited.
"This is so amazing, what will he do next."Alya said.
"Now let's end it here."Ryuki said and he pulls out another card with his symbol on it, he places the card on his visor.
FINAL VENT
Dragreder goes to Ryuki and flies around him, Ryuki goes into a pose while preparing himself, he then jumps into the air with Dragreder flying around him, he then goes to a flying kick position with Dragreder behind him, Dragreder then shoots a fireball sending Ryuki flying towards Magician with a fire kick.
"Rider Kick."Ryuki said.
Ryuki then hits Magician causing an explosion to appear, Magician was then sent flying to the ground again, he was fine despite the explosion only having a few burnt marks, his wand falls to the floor and Ryuki picks it up, Ryuki then snaps it into two and to his surprise a dark butterfly came out of it and Magician turned back to normal.
On top of a building was Ladybug anf Cat noir and they were stunned at what they just saw while blinking.
"Well looks like were not the only heroes around here anymore."Cat Noir said.
"But who is he, later we gotta catch the Akuma."Ladybug said.
Ryuki was looking at the Akuma then a yo-yo catches it, he looks behind to see Ladybug and Cat Noir with Ladybug pulling back her yo-yo to her and she opens it to reveal the akuma was normal again.
Ryuki then, goes up to them while Dragreder went back to the mirror world and said:"hello Ladybug and Cat Noir."
what's your name?"Cat Noir asked.
"I am Kamen Rider Ryuki."Ryuki said.
"Well nice to meet you Ryuki, it's interesting to meet another hero."Ladybug said.
"But you guys know me without the suit it's apollo?"Ryuki said revealing his true identity to the two.
"Wow I can't believe it your a kamen rider just like luz,amity,Anne,Sasha and marcy ."Ladybug said.
"I know right well if you guys need help call the realm defenders."Ryuki said.
"It will be cool to have little help, plus with those moves and that cool rider kick would be interesting to see again."Cat Noir said the he did a karate sound making Ladybug roll her eyes but Ryuki chuckled.
Then their miraculous beeped and LadyBug said:"Well we better go see you next time Ryuki."and they ran.
"Oh yeah, bye."Ryuki said confused."well I better go too."he goes up to the guy that was once the villain."Look I kow you must have been cheated on but doing this won't get what you want, so if you have a dream don't give up on it and just keep trying."
He thinks about, he then nodded and said:"your right, thanks Ryuki."
"No prob."Ryuki said.
He then goes running to a hidding place so he can go to the mirror world.
In nechros's lair, he was angry and said:"Ladybug you might have won this day with a new ally but next time you won't have the same luck and you Ryuki I will find out the secret behind your power."
Apollo opened a portal back to the boiling isle's,Apollo was back in his room, he was now ready for his new journey as a kamen rider starts now he must protect the innocent from e evil all along with his friends the realm defenders.
