Synopsis
Takeru, who has obtained his third Eyecon, is told by Sennin that the fourth one, Oda Nobunaga, is not going to be easy to obtain. A new client has come to the Strange Phenomenon Laboratory. Kuroda, the president of the Sengoku Corporation, has suddenly become cold and tyrannical and things have been seen floating around at the company’s headquarters. Could this be the work of a Ganma? Takeru starts investigating. Clues include the letter from a famous Japanese general and the suspicious behaviour of Sakuma, one of Kuroda’s assistants.

 * The Sengoku Corporation is a reference to Kamen Rider Gaim, as the titular Rider used a Sengoku Driver to transform and had the Sengoku War as a theme in the show.
 * , being a historic figure of great importance in Japanese culture, was referenced in the Kamen Rider series twice already in two Movie War films, both involving Kamen Rider OOO. Once in the Kamen Rider OOO portion of Movie War Core as a villain and the other in The Fateful Sengoku Movie Battle as the Warlord of the OOO Army. Also, Nobunaga Oda's armor is a motif of Gaim's Kiwami Arms.
