Kishin Corps

In the tumultuous backdrop of October 1941, as World War II escalates, an unexpected threat emerges from the stars—an alien invasion. While the conflict between the Axis and Allies continues to rage, a glimmer of hope lies in the hands of the Kishin Corps. Armed with colossal Geo-Armor Robots, or Kishin, crafted from the technology of a downed extraterrestrial warrior, they stand as humanity's last line of defense against impending doom.

At the heart of this struggle is Taishi, a teenager who unwittingly becomes embroiled in a high-stakes battle for a mysterious black attaché case left to him by his father, Professor Tokamura. This case holds the key to controlling one of the mighty Geo-Armor Robots, drawing the attention of the Japanese Kanto Army, the alien forces, and the Kishin Corps alike. As spies and armies converge, Taishi must navigate a perilous landscape filled with intrigue and danger, embarking on an extraordinary adventure that will test his courage and resolve.
