The episode begins with a confrontation between Aleister Crowley, Carmilla, and Shizuku. Aleister demands the return of a diamond, which is confirmed to be safely stored in London. Afterward, the focus of the episode shifts to the ongoing investigations.

Shizuku, Vera, and Aya are in the werewolf village of Wolphinhel. Aya announces that she has found the culprit behind the murders in both Wolphinhel and the human village of Heulendorf. She reveals that the true perpetrator is Louise from Heulendorf, who is also known as Nora from Wolphinhel and Jutte. Aya explains how she came to this conclusion, citing as evidence the absence of scales on the victims' bodies, tally marks on the cave walls, and the underground passage connecting the two villages.

Jutte confesses and gives her own account. She explains that she is the daughter of a werewolf named Rosa, who fled to Heulendorf years ago. After being discovered, Rosa and Jutte were burned, but Jutte survived and fled to Wolphinhel. There, she swapped places with Louise, who was also dissatisfied with her village. Together, they devised a plan to pit the two villages against each other. Jutte admits to the murders but reveals that her true motive was to help werewolf girls escape the oppressive customs of Wolphinhel.

Aya corrects her earlier conclusion and acknowledges Jutte's true motives. She decides to let Jutte go, who expresses a desire to "go somewhere fun." The episode ends with Shizuku and Aya discussing their next move, which involves traveling to London to find Aya's body.
