Just before the Druidon returned to invade Earth, three masters took much care in assessing their successors-to-be. Isuka, confident in her strength, could not accept Master Pink’s favoring Asuna. Her impatience was felt by Master Blue as well. At this time, a Minosaur suddenly appeared. This Minosaur used techniques similar to the ones Isuka had just learned. Could it have been born from her? And what is the secret behind Hana, the mysterious girl who appeared before Master Red?![4] This web series serves as a prologue to the TV show, taking place shortly after the events of 4 Week Continuous Special Super Sentai Strongest Battle!! (as The Director's cut version) and before the events of episode 1.
