12 Hours of Slave Labour (JP: Prison Camp Guardian Heroes Unite!) is an anime film based on Supernanny: The Theory Animated.


The Shōwa Prison Camp was known by many names "Supernannya Auschwitz", " Unit 731 of Supernannya ", The prison guards are mostly children, forcing their captives into 12 hours of hard slave labour.

One of them is a sadistic North Korean male guard named Ri Dae-Jung, a brutal female North Korean guard named Ri Min-Li, a sadistic Japanese doctor named Toshio Samo, a male South Korean guard named Park Young-Soo, a brutal Chinese female guard named Mei Cloud, and a female South Korean named Park Su-Hyun.


  • The title seems to be a loose pun on the Australian band 5 Seconds of Summer, but probably unintentional.
