"Undead Girl Murder Farce Episode 2: Vampire" begins with Godard, a vampire, and his son Raoul in the woods, where they are hunting a deer. Although Godard attempts to kill the deer with a rifle, he ultimately resorts to using his vampiric abilities to do so, highlighting his struggle with human norms.

Upon returning home, they are met with a grim sight: Godard's wife Hannah is found dead, presumably staked. The family resides in a large mansion, and the murder appears to have taken place in a room with a locked door, further deepening the mystery.

Aya and Tsugaru arrive to investigate the murder. They discover a bloodstained silver stake near the corpse, an empty bottle of holy water, a bloodstained coat, and a book left open on a specific page.

During the investigation, Godard is seen interacting with human reporters. One reporter stands out: a young girl with red hair who also appears in the series' opening sequence, hinting at a possible connection for future plot development.

Back at the mansion, Godard's youngest child, Charlotte, is seen playing with a dollhouse resembling her family. The positions of the dolls do not match any scene from the episode, creating an intriguing puzzle.

By the end of the episode, Aya and Tsugaru discuss the peculiarities of the case: a dusty container, an unlikely cause of death, and a series of events that don't quite add up. The open book near Hannah's corpse contains a poem that may hold a clue to the murder, but its meaning remains unconfirmed.

The investigation continues, and Aya and Tsugaru are close to solving the case. The episode ends with many unanswered questions, setting the stage for the next installment.
