Uchi no Shitsuji ni Negattanaraba 3 (Kadokawa Bunko)

[Machine Translation] Six servants gather at the Karasuma family's villa in France. At the suggestion of Vaz, who once served as the substitute butler of the Karasuma family, the servants of each family exchanged their skills, but then someone broke into the underground vault. The culprit is cornered in a cul-de-sac, but it is only five servants other than Korozuki who are there. Who planned to break into the safe? In addition, the news of the sale of the Karasuma family came to Hana-Ying upon her return to Japan. Hana-Ying, who had lost everything, was told by Korozuki ("I am the butler of the Karasuma family") that he was the butler of the Karasuma family.
