In the present, the only surviving Yokai, Kappa, tricks Sarutobi Sasuke and Kirigakure Saizo's descendants, Sasuke and Saizou, into releasing the Yokai by opening the "Seal Door". Now these two, joined by three other descendants of the great ninja, become the Kakurangers to fight the Yokai, with the aid of the Three God Generals.
