Terror Tower - S1.E18

Twenty Faces and Kouhei go head to head. Twenty Faces manages to distract Kouhei long enough to let Chiko rescue Shunka, only to be captured by the emotionless girl/weapon. Ken and Dr. Kayami meet up and discuss Twenty Face's "legacy" while heading towards Kouhei's laboratory. 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. Until Shunka escapes and creates a distraction, which Twenty Faces uses to blow up the machines. After the rumbling has subsided, Chiko is shocked to see Twenty Faces lying on the ground, unmoving.
