Godzilla: Tokyo S.O.S.

In 2004, Kiryu undergoes repair and modifications after its battle with Godzilla one year earlier,[a] while its remote pilot Akane Yashiro is sent to the United States for further training, with Kyosuke Akiba taking her place should Godzilla return while she is away. However, the Shobijin warn the Japanese government that Godzilla continues returning to the country because they used the original Godzilla's skeleton in Kiryu's construction. If they return the bones to the sea, Mothra will take Kiryu's place in defending Japan. Due to Mothra attacking Japan in 1961,[b] Prime Minister Hayato Igarashi refuses, but agrees to discontinue Kiryu once it kills Godzilla. Godzilla and Mothra fight, but the former has the upper hand. With the repairs finished, the government deploys Kiryu, but Godzilla knocks both it and Mothra out.
