The 40th entry of Toei's long-running Super Sentai series, following Shuriken Sentai Ninninger. The central story of Zyuohger revolves around the conflict between the Zyumans of Zyuland, humanoids with animal features, and their enemies, an alien force known as the Deathgaliens who use Earth as the field for their 100th Blood Game. Four of the Zyumans have protected their kind as the Zyuohgers, but when the human Yamato Kazakiri finds Zyuland, and accidentally separates the Zyumans from their people on Earth, Yamato joins Sela, Leo, Tusk, and Amu as the fifth member of the Zyuohger team to protect Earth from the Deathgaliens.
