Plot
As Ritsuka and Mash Rayshift to the final Singularity, they both see a vision of someone speaking of how they cannot bear the endless suffering of humanity, which they are subjected to due to their clairvoyance exposing them to all the horrors of the past and future. They decide that the only way to rectify the repulsive state of the world is to destroy humanity, and that to achieve this, everything must be redone and perfected from the beginning, from true nothingness. Their plan is to recreate the planet from its very origin, which requires the massive amount energy generated by incinerating all life across 3000 years.
Waking up from the vision, Ritsuka and Mash find they have arrived at Time Temple. Leonardo da Vinci reports a Beast is detected throughout the entire space. Lev Lainur Flauros appears before them, commending their efforts but still determined to stop them. Flauros then transforms into his Demon God and along with the other seventy one Demon Gods, attacks Chaldea. When it appears Chaldea will be destroyed, Jeanne D' Arc suddenly arrives, using Ritsuka as a beacon to summon an entire army of Heroic Spirits to aid him. The Heroic Spirits successfully open a path for Ritsuka and Mash, and as they head towards the Throne, Romani reasons that Solomon cannot be a fake, as the Time Temple was created from Solomon's Magic Circuits, and instead deduces something inside Solomon's body is controlling his corpse.
