Kouhei seems to have the upper hand as he unleashes his human experiments on both Chiko and Twenty Faces. He succeed in inserting the parameters he needed and 3 large towers appears in the center of Tokyo. Restrained by the children, the two can do nothing but watch as the city starts to be consumed by the light.
