Shido is shocked when Mio tells him that all the Spirits are dead. Stunned and unable to move, Mio nearly wipes his memories as Shido, but there is still one Spirit who's survived.
Shido is flooded with memories as the girl named Mio Takamiya stands before him. She was the person with whom Shido once shared his feelings when he was Shinji Takamiya. Meanwhile, Kotori and the others learn of Reine's true identity.
A full-scale confrontation between Shido and his friends Ratatoskr and DEM has begun. Kurumi and her clone, AST led by Ryoko Kusabe, join them, and as the battle intensifies, Shido confronts a horde of pseudo-Spirits, Nibeelcole.
Kotori and the others gathered on the bridge of Fraxinus learn that Kurumi has traveled back in time over 204 times to try and save Shido. Shido also tries to search his memories to learn who Mio Takamiya is, but.
As Shido rushes to the Spirits' side, Westcott blocks his path. Meanwhile, Tohka and the others find themselves overwhelmed and powerless before Mio's manifested Angel, Ein Sof Ohr.
A certain time, a certain place. Shinji Takamiya encounters a spatial earthquake, but finds a girl at the scene. She remembers almost nothing. Shinji gives her the name Mio and she goes to live with him and his younger sister, Mana.
The crew of Fraxinus sets about preparing for their battle against DEM with haste and high morale. The Spirits work hard to prepare snacks in order to encourage Shido and everyone else as the decisive battle draws closer by the hour.
