Dr. Over makes Ligon swallow a train near Lake Biwa to kidnap Suzuki, one of the passengers and head of the Kyoto Branch of Unicorn Organization. In the headquarters of BF Syndicate in the bottom of lake, Suzuki sees Over and Black Dia, new head of the Japanese Branch of the Syndicate. Azuma thinks that Over has killed Suzuki, for he is in charge of the conference of Unicorn leaders of the world which is going to be held in Kyoto. Under Azuma's orders, Daisaku (Johnny Sokko) and Minami go to Kyoto carrying the important papers concerning the conference. Over and Black Dia try to steal the papers, but they fail. Over changes Suzuki into a cyborg by performing an operation on him.
