A long time ago... There were Ancient Heroes in part of a guild known as Sword of Logos, the defender of the World. They use the power of books known as Wonder Ride Books.
11 years later, the enemy known as Megiddo was coming alongside Kamen Rider...
Tassel was still flying with his umbrella as he approaches his house.
Tassel: It's me, Tassel! Right now, I've got eyes peeled on Kamiyama Touma!
A book opens a pop-up page to show a theater-like scene. Showing what happened from the previous chapter.
Tassel: Touma has obtained the King of Arthur Ride Book from Avalon. But what's this "beginning of the trial"? Seems like Arthur might still have another little secret.
With Touma
Touma: I managed to use King Arthur's power... But-
He looked down at the Wonder Ride Book, in wonder.
Touma: Has he really deemed me worthy...?
Then all of a sudden a silver Wonder Ride Book flew at Touma.

He caught it in his hands and saw that it was bigger than a normal Wonder Ride Book.
???: It's up to you to draw on his true power.
Touma looked at him in question.
With Kento
Espada rolls on the ground struggling from defeat. Calibur goes up to him, preparing to stab his sword through Espada. Until he felt a disturbance in the force.
Calibur: Seems like it's time to leave.
Espada: Answer me! Why did you betray your comrades 11 years ago?! Answer me!
Calibur started walking away from Espada.
Calibur: You'll see soon enough.
As Calibur walks off. Espada reverted to his civilian form as he struggles to get up.
Touma came out of nowhere to find Kento.
Touma: Kento!
He continues calling out his childhood friend's name as he turns around and saw him laying on the sand.
Touma rushed to Kento and kneels to his level.
Touma: You alright, Kento?
Kento continues to struggle on getting up.
Kento: Have you unsealed your Holy Sword?
Touma nodded 'yes' and helps Kento get up and places him on a sand dune. He then goes deep in thought. Kento noticed the look on Touma's face.
Kento: Touma, did something else happen?
Touma: No. It's nothing.
{Flashback}
???: Let us meet again, once you have unlocked his true power. As for now... Hold on to this.
He brings out something in his robe and it reveals...
