Storious creates the Grimoire Wonder Ride Book using Legeiel, Zooous, Isaac, Tassel, and Charybdis' powers along with the Tome of Omniscience. Moreover, he reanimates the Sword of Logos' Four Sages. Meanwhile, despite struggling to stop Wonder World's collapse, Touma and his fellow swordsmen must face Storious if they hope to save the world.

One by one, the swordsmen fall for one reason or another as Storious overwhelms them. Touma attempts to face him alone, but learns a horrible truth regarding the Almighty Book. Meanwhile, as Wonder World vanishes and Earth collapses, a vanishing Mei reaches a decision as she attempts to reach a similarly vanishing Luna.
