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...
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.

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

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.
