The mansion is inhabited by a variety of eccentric and supernatural characters, including a vampire, a werewolf, and a ghost, each with their own quirks and personalities. Luchika’s primary role is to maintain order and cleanliness in the mansion, but her duties often extend to managing the chaotic and unpredictable behavior of its residents.

The narrative unfolds through episodic vignettes, with each episode focusing on Luchika’s interactions with the mansion’s inhabitants and the challenges she faces in her daily tasks. Despite her small stature and seemingly meek demeanor, Luchika is resourceful and determined, often finding creative solutions to the problems that arise. Her interactions with the other characters highlight her patience and adaptability, as she navigates the absurd and often humorous situations that occur within the mansion.

The series balances lighthearted comedy with moments of subtle tension, as the supernatural elements of the mansion occasionally lead to more serious or eerie situations.
