Sailor Trinitya (Takoka Minami) transformed into Sailor Trinitya using the power of the legendary treasure Master Force passed down from the ancient civilization of Lemuria to protect the peace of the streets. Around that time, Kurosawa Fumihiko, also known as Dr. Dokuro, planned to steal the source of Trinitya's power, Master Force, to transform into Zettsurin Kamen by absorbing the energy of super heroines. Using Minami's classmates, Dr. Dokuro set a trap for Trinitya and began brainwashing the students with Trinitya's training. And then... [BAD END]
