After a two-month hiatus, Re:Zero picks up right where the series last left off: with the aftermath of the attempt to sabotage the wedding of Regulus and Emilia. Now, Team Subaru launches their decisive counterattack. The episode begins with Liliana admiring Princess Priscilla as she dons her battle armor, while Priscilla suspiciously questions Anastasia's ("Fox") intentions.

Wilhelm and Garfiel encounter Capella, but their true adversaries are Kurgan (the blue-skinned giant) and the zombified Theresia. Wilhelm, torn between rage and grief, fights against the desecration of his deceased wife's memory, while Garfiel is haunted by Elsa's ghost. Meanwhile, Julius and Ricardo battle the "Gluttony" Archbishop Alphard, Felt and Otto face off against Lye, and Priscilla—alongside Liliana—confronts the fanatical Sirius.

The heart of the episode is the showdown between Subaru, Reinhard, Emilia, and the unbearably arrogant Regulus. He uses his wives as living shields but offers to release them and Emilia if Reinhard survives an unblocked attack. Reinhard dies briefly but is revived by the Phoenix Blessing and wields Emilia's ice dagger to deliver a devastating blow against Regulus—yet he proves invulnerable. Subaru vows to uncover the secret of his invincibility, while the traumatized women remain trapped under Regulus' psychological control.

The episode culminates in a nerve-wracking cliffhanger: Felix, keeping watch at Crusch's sickbed, is ambushed by the "Sin Archbishop of Lust" Capella, who reveals herself as a threat. Felix must now face the battle alone while simultaneously protecting the defenseless Crusch.
