力の源、そして物語の源であるワンダーワールドが消えていく。世界から物語が消えていき、世界そのものも消えていく。
ユーリは消えかかりながら前に進む。飛羽真に一目会いたい一心で歩を進めるルナ。最後の力を振り絞る賢人と蓮。そして、ワンダーライドブックが力を失い、ワンダーワールドが消滅する。消える世界。消える飛羽真。
全ては全知全能の書に記された定められた結末へ――。
「あなたには忘れられない物語がありますか?」
The source of the swordsmen's power and the source of stories, the Wonder World, disappears, and as the stories vanish from the world so does the world itself. Yuri advances onwards while faced with his own disappearance, as Luna races to see Touma before it's all over. Rintaro and Kento force themselves forward with the last fragments of their strength. Just then, their Wonder Ride Books lose their power and the Wonder World completely disappears. When that world vanishes, so does Touma. Everything is proceeding as it has been written within the pages of the Almighty Tome. In the midst of the world's greatest crisis, "Do you know a story you can never forget?"
