The M135 Frogman was an underwater construction labor produced by Hishikawajima Heavy Industries. The airtight Frogman was capable of working underwater at depths of up to 50 meters. Thanks to its large air tank, the Frogman had a longer operation time than other labors that performed underwater work. When the Tokyo police’s SV2 labor unit deployed to the Ark factory to thwart a plan to cause all the city’s labors to go berserk, many Frogman units activated on their own and attacked the police.
