In the sky of Wonder World, pieces of land were floating in the sky, bubbles in were the air, and Tassel was flying using his umbrella

Tassel: Hi, I'm Tassel! My heart's fluttering with excitement right now! "Why", you ask?

A book opens a pop-up page to show a theater-like scene. Showing what happened from the previous chapter.

Tassel: Unable to transform into Saber due to the seal on his sword, Touma has discovered a hint leading to Avalon. But even if he does reach Avalon... A certain someone lies in wait!

At the Northern Base

Leon was holding two Wonder Ride Books; Peter Fantasista and Tenkuu no Pegasus.

Leon: I'll never give up on myself.

He then walks toward Liberation.

Kento: Leon, what happened out there?

He ignored him and entered Liberation.

Touma: Liberation is some sort of training ground, right?

Sophia: Time flows differently in there, which places additional strain on the body when training.

She said while walking down the stairs.

Kaito: In the worst-case scenario, you may lose your life there.

Emma: Knowing that, he still...

???: His soul is hurting so much. Poor boy.

As everyone heard the small voice, they turn to the stairs to see a small green girl with two horns on her head sitting upon the steps.

Emma: And you are?

Allen: That's Nari. A friend of ours since the time Sword of Logos was built.

Touma was confused about the words Nari said.

Touma: What was it that Nari meant by Leon's soul was hurting?

Nari: My magic can feel the nature of the world and the souls of living creatures. Blades' soul is in pain after his fight against Zooous.

Sophia: There must be something he desperately wants to protect.

Touma: Or wants to gain.

Everyone then stares at Touma for what he said.

Machias: Elliot told me Zooous said that he killed his mother when she was Blades 11 years ago.

Touma: He wants to gain back the pride that he lost when his mother died.

Everyone then looked down from hearing that Leon lost his mother 11 years ago.

Touma: I vow to reach Avalon undo the seal on my sword. To protect the people I love.

Emma then blush after hearing what Touma said. Machias, Jusis, and Fie smirk knowing that she too has a crush on Touma.

Sophia: I presume you've obtained a lead on accessing Avalon?

Touma: Yes. The answer was in your books.

Three books were placed on the table as Touma and Emma debriefed on what they found.

Touma: "As the world come undone..."

Emma: "A dazzling light, accompanied by two dragons..."

Touma: "Will reveal the path to the gap between realms."

Emma: "The king sleeps within a gap in time." These were found in books on myths.

Touma: On the other hand; "When the 13 tales are linked to the blade, the gap between worlds will be unveiled." "The gap between realms".

Emma: "A gap in time".

Touma & Emma: "The gap between worlds".

They looked at each other because they said the same thing at the same time. Which made the three from Class VII laugh. Touma then continues explaining.

Touma: They refer to the same location, despite the differing literature. In short, Emma and I suppose that they're referring to a different realm.

Kaito: Another Realm?

Emma: As for this phrase... "The king sleeps within a gap in time." According to Arthurian legends... King Arthur hoped to escape death by reaching the island of Avalon.

Touma: Simply put, Avalon exists in another realm.

Class VII then changed their faces with shocked expressions that the legends of King Arthur were true with the members of the guild in question about this discovery.

Sophia: Merlin-sama has sent Arthur to Avalon a thousand years ago, since the night he fell, but he had never told me nor Allen nor even any of his students... To this day, no soul has yet to reach Avalon.

Then everyone looked down hearing that comment.

Touma: But... Calibur's likely caught on as well.

Kento then reacted to that comment.

Touma: He's after the great power that rests in Avalon.

Kento: Calibur has...?

Emma: Recently, their two dragon partners reacted strangely to each other.

Touma: "Two dragons". Which is why he wanted Brave.

[Brave: Even though I coming along, I can't fully fight against anyone in the state Rekka is in.]

Kento: Then Alangina and I are coming too. Touma won't be able to face him with his sword sealed.

Icchi: Then I'll-

Kento interrupts Icchi.

Kento: No. This is my duty.

Emma steps in closer to the table.

Emma: Then I should come as well.

Touma: No Emma.

He then turns toward the class president.

Touma: I need you to stay here, because if we don't make it back... you're the only one who also knows how to get to Avalon and save us.

Emma looked down, feeling left out for not going to help Touma in Avalon.

At the Megiddo Base

Calibur opens the book Storious gave him and started reading an ancient language of some sort of spell.

As he was reading out loud he raises his sword in the air and many Alter Ride Books float around him.

At the Northern Base

Touma: This is the method of accessing the other realm, along with this.

As he points at pages of books.

Kento: Ancient sword forms passed down through the generations?

He realized something.

Kento: That's it!

He then transformed into Espada.

Ikazuchi Batto!

Lamp do Alangina!

He faces the first door of the base.

He swings his sword down left, then he swings it down right, he swings his sword horizontally to the right. As he swings his sword Wonder Ride Books started floating around the base.

Emma: The sigil is made of 13 points...

Touma: So by tracing it with sword swings...

Kento swings his sword down left, and four books fly toward the door, then he swings it right up, and more four books flew toward the door, he then swings his sword horizontally to the right, and the final four books fly toward the door.

Touma: "When the 13 tales are linked to the blade, the gap between worlds will be unveiled."

Kento swings his sword up left, then he swings it right up, he then swings his sword vertically down.

The books form a star-like shape as Kento raises his sword. He swings right to left and stabs at the middle of the star make a hexagon with circles surrounding the books and lines connecting each book.

The power from the books caused the door to open with a bright light causing everyone to shield their eyes.

At the Megiddo Base

Calibur continues the spell as the Alter Books form the same hexagon as the one in Northern Base. Creating a bright light in front of Calibur.

He then walks into the light.

At the Northern Base

Touma then walks up to the light.

Touma: Let's make for Avalon, Kento.

Kento: Right.

They walk into the light.

Back to the Story

Touma and Kento were in a void showing backgrounds of all the different realms from; the Fire Realm, to the Ocean Realm, to the Lighting Realm, to the Land Realm, to the Sky Realm, and finally the Mirage Realm.

They then see a light appear from all the illusions.

Touma: "A dazzling light will reveal the path to the gap between realms." That must be it! Let's move!

As they ran to the dazzling light, they had no idea that Calibur was following them.

At the Megiddo Base

Storious: Calibur's on his way to the gap between realms. Isn't it time we accelerated the erosion?

Zooous slammed his claw on the table.

Zooous: Then let me at 'em!

Storious: No. I insist Legeiel take the stage. Along with Bular.

Zooous tch off after hearing the order. Bular grinned that he finally gets to be in action for a long time.

Storious: Don't you think it's about time you showed us your best?

Legeiel then scoffed at the offer.

Legeiel: If you insist-

He opens the Alter Book in his hand to summon the Megiddo.

Medusa Jaden!

Legeiel: Let's try this.

At Thors Military Academy

Alisa and Elliot were walking down the hall of the school.

Elliot looked at the message Touma sent them via ARCUS.

Elliot: Touma said he's going on a field trip to unseal his sword.

Alisa: It's good to hear that. He'll need Rekka unsealed in order to fight. But I'm still worried about Leon.

{Flashback}

Leon: Insta's really useful, isn't it?

(Scene Change)

Leon: This one has to be defeated by my hands!

Zooous: Boring. You're not even worth killing.

{End of Flashback}

Alisa: I wonder if he's okay...

She said concerned.

Alisa: Then we should get some éclairs for him.

To try and be cheerful.

With Leon

Leon was still in Liberation kneeled to the ground with all three slots of his Swordriver filled with blue Wonder Ride Books. He was exhausted from training.

{Flashback}

Leon was an eight-year-old boy in Liberation, training with his mother, the previous Blades.

Young Leon: Can I become a strong swordsman like you, mother?

His mother's name was Asuna Shindo

Asuna: Leon. You're like your father. He too wanted to be a swordsman. The path of a swordsman or woman has no end. Don't ever slack!

Young Leon: Hai!

{End of Flashback}

Leon: I must become stronger to avenge my mother...

He slowly gets up.

Leon: So my father can rest in peace.

Then grabs the handle of his sword and tries to draw it out.

But he was thrown out of balance instead.

He tries many times but never managed to be successful to change.

Leon: I have to master the power of the three books she left me... For my family's legacy.

He slowly gets up to try again.

???: You can not continue like this, Young Master.

Leon then turns around to see a familiar face to him.

Sebastian Michalis: A mysterious butler with an unknown origin.

Leon: Sebastian... How can I become as strong as my mother?

Sebastian: Your mother's strength came from believing who she was. You need to believe who you are, Young Master.

(Scene Change)

Rai was running with Laura and Gaius at his side.

Rai: Daishinji's info would put it around here...

Gaius: Are you sure Rai?

They stopped to see Legeiel and a Megiddo with snakes on her head.

Laura: There they are!

As she ran towards the Megiddo. Rai and Gaius then followed her.

With Legeiel

Legeiel: Now then, Medusa... Dye in the humans in fear.

Medusa laughs with excitement.

Medusa: As you wish.

She opens the blank Wonder Ride Book and the giant book appeared taking the piece of the world away.

Laura, Rai, and Gaius stopped before they could get hit by the forcefield.

Laura: We're too late...

Gatring! Gatring!

Rai picks up his gatrikephone.

(Scene Change)

In the Mirage Realm, many elves were enjoying their time until they felt a tremor in the earth.

At the Northern Base

Kaito was on the phone with Rai.

He then urns to Icchi.

Kaito: Icchi, it's time.

Icchi: Okay.

He gets up and heads towards the door.

Icchi: Leave it to me-

Kaito: Hang on!

He stops the ninja.

Kaito: Something's different. Three locations in three different realms have been teleported!

Everyone in the base was all shocked from heard the report Kaito got.

Sophia: Three, simultaneously...

With Touma and Kento

They were in the gap between the world. Kento and Touma search for the next way to Avalon.

Touma: Kento!

As Touma spotted something.

Touma: We're getting closer! Avalon's just ahead.

As they continue on, Touma felt something behind him. They turn around to see Calibur in his civilian form, but a bright light made it impossible to see his face.

???: I applaud you for getting this far.

He drags Ankokuken Kurayami in the sand.

???: However, do you have what it takes to obtain that power?

He stops walking and brings out his Wonder Ride Book.

Jaaku Dragon!

He opens the cover page.

"Katsute sekai o tsutsumikonda kurayami o unda no wa tatta ittai no shinjuu data..." (It was only one god beast which birthed the darkness that once enveloped the world...)

He then placed his book on the sword's scanner.

Jaaku Read!

Then placed the book in his driver.

He lifts his sword up.

???: Henshin!

He used Kurayami to press the button on top of the driver. Opening Jaaku Dragon.

Ankokuken Kurayami!

He slashes his sword vertically downward before Jaaku merges with him.

Get go under conquer than get keen. Jaaku Dragon!

Kurayami Honyaku! Hikari wo ubaishi shikkoku no ken ga, reikoku mujou ni ankoku ryuu wo shihai suru! (Kurayami translation! The jet-black sword that robs the light ruthlessly rules the dark dragon!)

Touma: I knew he'd come!

Kento then ran in front of Touma.

Kento: I'll defeat him!

He placed both his Wonder Ride Books in his driver. As Espada transformed, Calibur walks up to the swordsman of lightning.

Espada: I'll take Jaaku Dragon's Wonder Ride Book from him!

He takes his Gatrikephone

Gatrike Phone!

Espada: Touma, you go on ahead!

He fold his phone and threw it behind him as it transform.

Ride Gatriker~!

Scene Change

As Elise was in Wonder World where a part of the city was taken. She was cautious in the area.

While Rai, Laura, and Gaius were scouting the area for the Megiddo. Icchi then came to the scene with Machias, Jusis, and Fie behind him.

Everyone: Ogami-san!

Rai turned around to see the four teens.

Rai: Hey!

Everyone then sees that the people of the city were turned to stone.

Rai: What the-

They hear gunshots and see a soldier shooting his gun at the Megiddo.

Soldier: Stop! Don't harm these citizens!

As the Megiddo changed targets, her eyes glow red and the soldier turned into stone.

Rai takes out his Wonder Ride Book.

Genbu Shinwa!

Rai: Henshin!

Icchi takes out his Wonder Ride Book.

Sarutobi Ninjaden!

Icchi: Henshin!

They merge with their Spirit Book partners and transform into their Kamen Rider Forms.

Dogo! Dogo! Dogouken Gekido!

Fuusouken Hayate~!

They all charge at Medusa.

Buster: Make sure you don't stare at its eyes!

Laura: I'll make sure of it, Uncle Rai!

Kenzan: Don't wanna turn to stone after all!

Jusis: I don't plan on being a noble as a statue!

Machias:  I don't plan on losing to you!

Buster slammed his sword at Medusa as she got pushed back a few meters. Gives Machias a chance to shoot at her with his gun. But he hit the Megiddo's chest and she stumbled back again, then Kenzan came in from the right and Gaius came from the left.

Medusa tried to slash at Kenzan, but luckily he jumped over the Megiddo and strikes her as she turned around and Gaius stabbed her in the back with his spear.

Then Buster and Laura slash their swords horizontally at Medusa. The Megiddo then rolls to the ground.

As Buster continues the attack, Zooous came out of nowhere in his monster form. Kenzan was going to attack as well but stopped as Zooous appeared.

Legeiel was watching from the distance along with Bular and they decided to join in the fun.

Legeiel was the first one to jump off the bridge and he transformed into his monster form.

Bular followed him.

Kenzan then turned around to see Legeiel and Bular.

Kenzan: Two more big strong-looking ones here!

Buster: Legeiel. Bular.

He said in a familiar and angry way.

Gaius: Rai-san, who are they?

Buster: Legeiel, the ruler of the Phantom Beast, and Bular, Son of Gunmar, the Gumm-Gumm Prince.

[Genbu: They have slain many of our past swordsmen for generations.]

Buster: And now... I'm going to return the favor to my ancestor!

He charges at them. While Elise was watching from behind a water fountain.

Elise: What's going on? This all looks like it's getting worse...

Unknown to them. Storious was behind her with an elf hostage in his hand.

With Touma

Touma gets on the Ride Gatriker, as he was about to ride, he thought of an idea.

(Scene Change)

Espada charges at Calibur with his sword in front of him but the Swordsman of Darkness blocked his attack and threw him off.

The Swordsman of Lightningturns around to attack again but Calibur blocks then threw Espada's sword and strike him in the chest.

Espada gets back up and tries to strike him but he dodged quickly and strike through Espada's chest again.

They clashed against each other.

???: Kento!

Espada quickly rolls to the ground away from Calibur as he got hit by Touma on the A-TV.

Touma stopped the vehicle and turns to Espada.

Touma: He's following us to Avalon regardless. Let's settle thins there!

Espada: Alright!

He pressed the gold book in the left slot of his driver.

Lamp Do Alangina!

Then his magic carpet appears and he flies with Touma riding the A-TV toward Avalon.

Calibur gets up and follows them.

With Rai

Buster was clashing with Bular when all of a sudden Desast jumped him. Luckily Buster quickly blocked his attack and Bular backed away.

Desast randomly swings his sword at Buster.

Desast: I knew things were getting fun!

He then clashed his sword with the King of Parenting.

Then Kenzan noticed he was alive still.

Kenzan: Hang on, didn't I already beat that one?

Buster: These guys are annoying because they don't just die like that!

He pushed Desast back, then Legeiel came in, but Buster kicks him away. Desast taps him with his spike sword then Buster turns around and clashed his sword with him.

Kenzan: But hey, this situation's super exciting though!

Zooous then charges at Kenzan with Legeiel behind him. Kenzan somersaults to block Zoous and tries to hit Legeiel, but Legeiel dodged the attack.

Gaius and Laura clashed with Bular holding him back.

Gaius: It's not about how exciting it is!

Laura: It's about saving people!

They pushed Bular away then Machias and Fie hit him with their guns. Buster threw Desast off and Kenzan kick Legeiel's sword away. Legeiel tries to hit the green ninja, fortunately, Kenzan dodged and strikes Zooous.

???: Sorry to spoil the fun, but here's where it ends.

They turn around to see Storious had Elise in his grips along with a fire elf.

Named; Azari Firedancer

Machias: Elise!

He said recognizing one of the hostages.

Gaius: You know her?

Machias: Elise is Touma's little sister.

Everyone was shocked after hearing what Machias said.

Laura: Oh no.

Elise: Sorry, he got me...

At the Northern Base

Kaito was sitting on a chair at the table. Sophia came up to him with Allen behind her.

Sophia: Slash...

He looks up at her.

Kaito: I need a bit more time...

Scene Change

His sword kept beating. Making a sound like it had a heart.

Scene Change

All of a sudden the doors to Liberation open with Leon exhausted. Kaito turned around to see him on the floor.

Kaito: Leon.

He slowly gets up and weaves on the walls.

Tenkuu no Pegasus! (Heavenly Pegasus!)

At the Gap Between Worlds

Touma and Espada continue running to Avalon. They were under a light.

Touma: We're here!

They look around to see if where they got to is Avalon.

Touma: This is Avalon...?

Unknown to him Calibur was about to strike at Touma from behind, but luckily Espada pushed his best friend aside and the transformed swordsmen clashed their swords.

Espada: No you don't!

He pushes Calibur away from Touma.

Touma: Kento!

Calibur threw Espada off him.

Calibur: Get out of my way!

He then strikes him horizontally on his chest.

Espada rolls on the sand dune. Calibur take out his Wonder Ride Book and placed it on the scanner.

Hissatsu Read!

He placed the book back into the driver then presses the trigger.

Kurayami Hissatsu Geki! Shuutoku Issen!

Calibur slashes at Espada as Jaaku came out of the sword and charges at Espada.

But he uses Alangina's power to black the attack but was unable to and flew a few meters backward.

Touma: Kento!

Calibur turns towards Touma.

Calibur: Now hand him over! Give me Brave Dragon!

He charges at Touma.

As Touma gets ready for the attack, his swordriver glows bright red, as well as Jaaku Dragon Wonder Ride Book as they were going to clash, both Brave Dragon and Jaaku Dragon came out and flew in circles around the light.

[Brave: Jaaku!]

[Jaaku: Brave!]

Touma: The dazzling light and two dragons are overlapping!

The light and the two dragons flew down to the ground and the light became brighter and transformed into a door.

Calibur: The door to Avalon has opened!

He then walks up to Touma, but Espada came in and holds him back.

Espada: Go, Touma!

Touma: Okay! I promise I'll come back!

Touma runs to the door. Calibur breaks out of Espada's hold and strikes him on his arm. Espada then swings his sword, but Calibur dodged and strikes his chest again.

Scene Change

Touma runs through the doorway and has made it to Avalon which was a bright area. White as far as anyone could see.

Touma: Is this Avalon...? There's nothing here!

He continues looking around until he heard a voice.

???: There is nothing if you believe so.

He turns around to see a monk with a hood on.

He couldn't see his face. It was all a bur because of the brightness in the realm.

???: There is something if you believe so.

Touma: Who?

???: Stop seeking the great power.

Touma: I need that power!

???: Stop searching. Stop looking. Stop-

Touma: I want to save the world! To do that, I have to restore this sword to normal!

???: Stop searching!

He kept on saying it again and again.

Touma: Where is it?! Tell me where!!

He charged right at the monk.

With Kenzan and Buster

Zooous strikes him on his head than two times on his chest, as the final blow, he threw an uppercut and threw toward the fountain.

He then walks up to Storious with the girls.

Zooous: I don't need your dirty tricks to beat them!

He grabs the girls with his claws.

Zooous: Might as well gobble them up.

???: Not the blue hair girl. Just the redhead.

Bular came in a took Elise out from Zooous' claws.

Bular: I'll keep this one as bait to bring Saber to us.

The two Megiddo leaders looked at Bular and Storious smiled from hearing his idea.

Storious: Excellent.

He turns to Zooous while he holds Azari.

Storious: Zooous. Lunchtime.

Zooous nods from the comment and threw Azari in the air.

Buster swings his sword at Desast and saw the elf in the air.

Buster: No!

Zooous looks up and Storious faces Zooous as he's ready to eat.

Storious: Help yourself.

He walks away as Azari falls as everything began going in slow motion.

Inner Azari: "Farewell... Everyone..."

As she continues to fall Zooous open his mouth as wide as he can. Then all of a sudden Leon came in his Blades form and slashes Zooous on the side and caught Azari bridal style.

She then saw she was alive and faced the man who saved her.

Blades: Sorry to keep you waiting, Azari.

She then slowly smiles at her hero.

Azari: Leon...

Buster threw Desast off him and sees Blades.

Buster: Leon!

Then Kenzan popped out to see Blades as well.

Kenzan: Leon!

Zooous came back up and saw Blades.

Zooous: You know you stand no chance of beating me!

Blades placed Azari down on her feet.

Azari: Thank you so much! And it has been a while, Leon!

Blades: Of course. Leave the rest to me. Elliot, Alisa!

Elliot and Alisa came in after saving Elise from Bular.

Elliot: On it! The rest is up to you!

They took Elise and Azari to a safe place.

Blades then turn to Zooous and brings up two of his Wonder Ride Books and opens their covers.

Peter Fantasista!

Tenkuu no Pegasus!

He opens the cover page.

"Katsute souhaku no tsubasa o motsu shinjuu ga ten-kara kagayaki maiorita..." (There once was a God Beast with pale wings that shined down from the sky...)

Leon: Pegasus... Please lend me your power as you did for my mother.

[Pegasus: Of course, Leon. As Asuna was your mother, she was my best friend... She was the first female elf to hold a Holy Sword and for that she became famous. Now it is your turn to follow mother's footsteps.]

As he nods at the Navy book, he placed the two books in his driver, and then he drew his sword out.

Nagare Batto!

He was then taken to his water-surrounded library as three giant books behind him opened and the final two Spirit Books merged with him and Senki.

Aoki yajuu no (Aoki Yajuu no!) tategami ga (Tategami ga!) sora ni nabiku! (Sora ni nabiku!) Fantastic Lion! (The mane of the blue beast flutters in the sky! Fantastic Lion!)

Nagare Sansatsu! Konpeki no tsurugi ga kiba wo muki ginga wo seisu! (Nagare; Volume 3! The azure sword turns its fangs and controls the galaxy!)

He has transformed into Fantastic Lion.

Blades: Ikouze, Min'na!

[Senki: Yeah, Aibou!]

[Peter: This is going exciting!]

[Pegasus: This moment will make us legendary.]

Leon: In the name of Suiseiken Nagare and my partners Lion Senki, Peter Fanasista, and Tenkuu no Pegasus I shall defeat you!

Azari then became shocked by Blades' quote and hearts started forming around her.

Zooous charged at Blades and swings his swords left and right. Blades swing his sword in a circle to block the attacks and strikes him down vertically then horizontally. Making Zooous stumble backward.

Blades then pressed Pegasus's Wonder Ride Book then jumps and does a backflip then charge right at Zooous with water jets.

Their swords clash with each other and water forms around Blades he slashes through Zooous and the water has gone through him as he turns back to normal.

Buster and Kenzan saw the power Blades used as they were fighting Desast and Medusa.

Buster & Kenzan: He's strong!

Zooous was so frustrating that he ran away.

With Touma

He continues arguing with the monk.

Touma: Where is it?!

???: Nowhere if you believe it so. Somewhere if you do.

Touma: Where?!

As he charges at the monk.

He then stopped and realized something the monk said.

Touma: It will be there if I believe it so...

He then closed his eyes and the area became pitch black.

As his eyes were closed, Wonder Ride Book appeared flashing gold and disappeared in front of him. Then it did the same thing but behind him.

Inner Touma: Right there!

He reached his hand out and as he opened his eyes, he saw a Wonder Ride Book in his hand.

King of Arthur!

???: Now begins the trial as to whether you're truly worthy of it!

Then he was teleported to a cave.

He turns around to see an army behind him.

They charge right at Touma.

With Leon

Blades was facing Legeiel and Medusa at once.

He blocked Legeiel's sword coming in from the right and then pushed him away and went for Medusa. He strikes her on her chest vertically.

Kenzan and Buster were both chasing after Desast.

Kenzan kicked Desast on his chest and Buster slammed his sword on top of Desast. Kenzan tries to hit him with his sword on the side but Desast blocked it.

Blades now clashes with Legeiel. But unknown to him Medusa was preparing to turn him to stone.

Medusa: Time you went rigid with fear!

Her eyes glow red at Blades.

Luckily he uses the water like a mirror and then she has gone blind after seeing her own eyes.

Blades: By my pride as a swordsman, I will protect this world's balance!

He place his sword in the driver and pressed the trigger.

Hissatsu Dokuha!

He then drew his sword out

Nagare Batto!

Pegasus! Lion! Peter Fan! Sansatsu Geki!

Leon/Senki/Peter/Pegasus: Hydro Vortex!

W-W-W-Water!

Medusa tries to whip at Blades, but luckily he blocks them as his sword charges with water covering upon the blade.

He then sends a geyser and lifts Medusa into the air, he jumps and slashes through her and lands on the ground.

An explosion of water accrued behind him as the Megiddo was destroyed.

The piece of the city returned to the original world and the people who were turned into stone reverted back to normal.

As the Riders were finally back to their civilian form.

???: Leon!

He turns around to see Azari rushing to him and by surprise, she jumped on him with her arms around his neck hugging him.

Azari: You did it, Leon! Thank you! Yayyyyy!

Leon: Azari! Please...

Everyone looked at Leon and watched Leon get his reward for saving a girl.

With Touma

A soldier caused Touma to jump to another part of the cave. He turns around to face them and opens the Wonder Ride Book in his hand.

"Toaru kishiou ga furi orosu kanzen chouaku no hitotachi..." (A certain knight king swings down the sword of poetic justice...)

He placed both Wonder Ride Books in the driver's slot and finally, he drew his sword out and opened the books.

Rekka Batto!

Touma: Henshin!

He then makes his flaming X slash and fire burst out as he transforms.

Nisatsu no hon o kasaneshi toki seinaru tsurugi ni chikara ga yadoru! Wonder Rider! (When two books synthesize, the sacred sword is infused with power! Wonder Rider!)

He transformed into the Wonder Rider; Dragon Arthur.

Dragon! Arthur Ou! (Dragon! King Arthur!)

[Brave: Touma! You did it!]

Touma: No the time to celebrate just yet partner.

[King Arthur: He is right. It is time to see if you're worthy of my power.]

As a dozen soldiers charged at him, Saber used Kingexcalibur to slash at the incoming soldiers.

Jakīn!

Then more came and he used Kingexcalibur again and slash at more incoming soldiers.

Jakīn!

And as the final wave came he spins around and Rekka started to glow and use both of them to strike them down.

Hissatsu Dokuha! King Slash!

The entire army was defeated by energy slashes.

With Tassel

Tassel: Touma and Leon have each achieved a major goal respectively! But what might this "beginning of the trial" be?

He turns around to look at the distance of Wonder World.

Tassel: Isn't it just exciting?

With Touma

Touma was reverted to his citizen form and was exhausted from using the power of the Wonder Ride Book.

Inner Touma: I managed to use King Arthur's power... But-

(Flashback)

???: Now begins the trial as to whether you're truly worthy of it!

(End of Flashback)

He continues looking at the Wonder Ride Book wandering about its power.

Ending Dance Time

Shows three riders clashing their swords on top of each other.

(Instrumental) Touma and Class VII, point at the camera and hold their Wonder Ride Books, and they started dancing.

(Michi naru mono ni nomikoma reru toki) The teens raise their arms up in the air. Then it shows Saber practicing his swordsmanship with Brave next to him.

(Yami wo kirisaku no wa hikari ka tamashii sa) Then shows Emma taking the lead, then moves to the back while rolling her arms before Leon takes the lead. Changes to Blades practicing his swordsmanship with Senki next to him. As everyone explores the museum. Then back to the gang dancing.

(Mazu jibun jishin wo kaero!) They swing their right arms down and swing back before spinning around.

(Henshin!) Pages fall to the floor. As for acting like they drew their swords out.

(Aijou koeru youna seijitsu-sa de junan no hate mi ni kizamu) Two riders were riding on their bikes in Wonder World.

(Fumetsu no kokoro wa kokoda to) They continue riding their bikes.

(Kakikaero yume wo monogatari no ketsumatsu wa kimi ga kimeru) The gang was hiding in the museum behind the big sculptures, before they pop out from their hiding spots with goofy smiles.

(Kamen Rider Saber!) Saber then slashes his sword, as it changes to Touma and the others slashing their pens down and lifting their right hands in the air. As they smile putting their hands over their head throwing out, before rolling their hands, and they the kicks and punches, as they're stances. Then it shows three Kamen Riders, each in three different worlds.
