With no actual Island Challenge on Poni Island, Ash decides to battle Island Guardian Tapu Fini in place of the Challenge, so he and Kiawe rush to the Ruins of Hope. However, when Tapu Fini does not appear, Ash and Kiawe decide to battle to pass the time. Tapu Fini is angered by this and captures Ash and his Pokémon. A mysterious old man tells Kiawe that in order to free Ash and appease Tapu Fini, Kiawe must get an item from Tapu Lele on Akala Island and return with it to Poni Island before a certain time limit expires.
