Youkai Gurentai

In the shadow of Mt. Fuji, a mysterious castle suddenly materialized, unleashing a horde of Youkai upon the world. As Japan's population continued to decline, the government was forced to confront the reality of a dwindling workforce. In an effort to address the labor shortage, they implemented a radical plan to integrate the Youkai into human society. However, this integration led to a surge in conflicts between humans and Youkai, as the two species struggled to coexist. In response to the growing tensions, the Japanese Self-Defense Forces (JSDF) took it upon themselves to establish a special task force, the Tachikawa Task Force, with the aim of resolving the issues arising from this new society. As a covert operation, the Tachikawa Task Force would employ "tactical solutions" to address the various problems that had emerged from the integration of Youkai into human society. Their mission was to maintain order, protect human interests, and prevent the resurgence of conflicts between humans and Youkai.
