Using the power of the Mark of the King, Yamato and the four Zyuman transformed into the Doubutsu Sentai Zyuohger! Even though they defeated Deathgalien's first attack, the Zyumans lost one of the six Mark of the Kings needed to open the portal back to Zyuland.
Now stuck in the Human World, Yamato feels responsible for what happened and takes care of the four Zyumans and have them stay with him in his uncle's place. Sela, Leo, and Amu accept the offer, but Tusk refuses and goes off alone. Concerned about Tusk, Yamato goes after him only to encounter a new Deathgalien.
