On a day at the beach, Ashura kidnaps Sayaka and threatens to publicly humiliate her by cutting off her swimsuit if Kouji and Mazinkaiser do not surrender. Kouji is brought aboard the submarine Salude, but manages to escape and rescue Sayaka with Boss' help. Venus and Mazinkaiser make short work of the submarine. This episode is somewhat infamous for its crude sexual humour and fan service nudity.
