A monster named Xibalba appears in the city. Then a boy named Frey appears and summons Heart Roidmude. The next day, Takeru and Makoto appear to the scene and encounter Frey and Heart Roidmude. Takeru and Makoto transform into Ghost and Specter respectively and take on Heart Roidmude.

At Takeru's place, Freya tries to convince Takeru and others that she's on their side, but they remain skeptical, still wary about Freya's unknown origin and her true intentions. Eventually Takeru persuades them that they should trust Freya for now, pointing that without Freya's help, he wouldn't be able to get Drive's Eyecon and defeat Heart Roidmude. Meanwhile, Frey summons Terror Dopant while voicing to himself the question of what Freya will do.

Frey summons Lord Baron and Sagittarius Nova and orders Lord Baron to fight Ghost. Lord Baron appears before Takeru and Akari and Takeru transforms into Ghost to fight Lord Baron. During the fight, Lord Baron asks Ghost why he fights.

Takeru and Akari return home only to bump into Freya. Takeru asks Freya what those monsters were talking about but she refuses to answer. Meanwhile, Makoto and Onari are about to come back but Sagittarius Nova appears and attacks them. Makoto transforms into Specter and fights Sagittarius Nova.

Takeru and Makoto asks Freya and her brother Frey what they are after. Turns out that Freya and Frey are working together. Frey tells Takeru that he'll explain if he can defeat the monsters that Frey summoned.

As Specter holds off Xibalba, Wiseman resumes his magical assault against Ghost who, realizing that Wiseman is meant to give him power, asks why they need to fight. Wiseman maintains that no one can escape the fate of despair, daring Ghost to show his determination if he wants to stop it.

Having been entrusted with the Kamen Rider 45 Ghost Eyecon by Freya, Takeru walks with Makoto, pondering Freya's words that the "true enemy" is coming. The pair are interrupted by the sight of something descending to the Earth, and move to face it.
