Output (English): After conducting a praying ceremony, the three oldest children of the alien Fog Mother hunt for an ideal human to feed to their newly hatched siblings. They find Kana, the younger sister of environmentalist reporter Kouji Segawa, when he is investigating pollution at the lake. Protecting Kana from the villains as they escape, Kouji is thrown over a cliff by the reptilian Agito and dies; Kana is taken by the insectoid, Zu. Kouji is resurrected by the Earth Spirits as Kamen Rider J to fight the Fog Mother with the Earth Spirits emissary, Berry, as his guide. With Fog Mother sensing Koujis presence, Agito tries to finish the job and is killed by J. Kouji enters the Fog Mothers domain, facing Zu in her true form. J kills Zu as they crash into the fortress which is Fog Mother. After Zu dies, Kouji learns about Fogs intention to let her new brood devour humanity as Garai completes the ritual, sends Kana to the hatching chamber and manhandles Kouji. Berry intervenes to free Kana from Fogs spell before he is struck down by Garai; Kana is sent down to her death, and Fog Mother begins attacking a nearby city to prepare for her childrens awakening. J fights Garai in his true form Cobra Man in a heated battle. After he kills Garai, J is digested by Fog Mother as he tries to save Kana. Absorbing the life energy around him, J kills Fog Mothers newborn offspring, escapes from her bowels and assumes the Jumbo Formation. After ripping Kana out of Fog Mother, J kills the monster. Escaping Fog Mothers destruction, Kouji brings Kana to a peaceful place as Berry watches from a distance.
