The Kingdom of Light, which had lost its plasma spark, fell into a huge crisis. In order to save the frozen Kingdom of Light, Mebius, who had escaped from the disaster, found Leonix of Earth, Lei, hoping to use his power to save the Kingdom of Light. However, he suddenly encountered violent space turbulence on the way back. In order to protect Lei, Mebius burned all his light power, but the two were eventually swept away by the torrent of time and space.
When consciousness returned, Mebius lost his giant power and turned into a human body, Hibino Mirai, wandering alone in a strange and alien world. In order to save his frozen hometown and find the lost Lei, he immediately embarked on an unknown road of search.
