In Jamanga's Base, Thunder Key with the strongest magic was fused with a part of the body from Jack Moon, and the clone, Elemoon was born. Elemoon is on the mission of defeating RyuKenDo and is rampaging by shooting lightning everywhere. Kenji and Fudou are powerless against the power of thunder. Devices in S.H.O.T.'s base are also short-circuited due to the influence of overcurrent, and Commander Amachi will carry out unprecedented ground operations. It was a strategy to hunt down Elemoon and capture it in an armoured tank!
Yack Moon revela estar com a posse da misteriosa Chave Trovão, usando-a para criar um clone seu, Elemoon. O clone do espadachim ataca Akebono, forçando Ryukendo e Ryugan'o a entrar em ação para pará-lo. Quando a Chave Trovão se mostra muito poderosa para o falso Moon, Kenji e o vilão verdadeiro se enfrentam para obtê-la. *Parte chave deste capítulo: A Chave Raio, é um complemento que precisa ter muito cuidado ao usá-la.
