Strange Steel Fairy Rouran

In the bustling metropolis of Tokyo, a clandestine group known as Shiromorishuua unleashes a colossal creature, threatening the city's safety. The peacekeeping organization ASY responds with its own formidable creation, the Gousen, a metal fairy designed for combat. After an intense battle, the Gousen successfully drives the monstrous threat into the depths of the ocean. However, the victory is short-lived as a mysterious girl named Rouran appears, suspended in midair and radiating light. With the ability to unleash powerful beams, she strikes unexpectedly, leaving everyone—especially herself—wondering about her true nature.

Haunted by questions regarding her identity and purpose, Rouran grapples with her transformation into a vengeful force whenever she encounters the Gousen or reanimated beings known as Kyoushi. In the midst of her uncertainty, she finds solace in the company of Tetsuya, who offers her support in the unconventional community of Tokyo Arcadia. Here, amidst a gathering of expatriates and those seeking refuge, Rouran navigates the complexities of her existence while uncovering the secrets that bind her to the ongoing conflict.
