Luka Luka★Night Fever

Luka Luka★Night Fever is a derivative of Megurine Luka, however Luka Luka★Night Fever is an intruder to the Vocaloid Household. The only thing she can say is "Luka Luka★Night Fever" and does the dance to those lyrics when she says it.

On August 4, 2020, Luka Luka★Night Fever entered the Vocaloid Household. She committed tax fraud and also killed Yuuma before going into the bathroom on the second floor.

The events were somewhat similar to The Bathroom 2 Incident of 20, though not exactly the same. Luka Luka★Night Fever began to spin in the air like a ceiling fan and began shitting, resulting in the bathroom being entirely covered in her shit. Multiple family members attempted to kill her, but she was unable to die during these events. Megurine Luka then came in to stop the madness by singing +IMPALE, which resulted in Luka Luka★Night Fever fading away.
