became the Lord of the Eternal World in Tokyo.

In the bustling city of Tokyo, Uesugi Tetsu discovers an extraordinary ability to draw cards that transform him into demons and ghosts from historical legends. With each transformation, he gains access to their unique powers and strengths. Moreover, whenever these creatures perish, they turn to ashes, providing him with assistance for his next card draw, allowing him to tap into a vast array of legendary entities. As the boundaries between the human world and the realm of demons begin to blur, a thousand-year-old world rises from the abyss, reconnecting with the mortal realm. This marks the beginning of a golden age for demons and ghost stories, where powerful rulers from throughout history seek to exert their influence. The twelve crowned kings are dispatched to roam the world, while Shuten-dōji arrives with a vast empire, and Aoandon attempts to unleash the Night Parade of a Hundred Demons once more. Meanwhile, the warlords of the Warring States period mobilize their armies, setting the stage for a grand conflict. However, Uesugi Tetsuya, possessing unparalleled demonic talents, awakens to sever the ties between Yin and Yang, potentially disrupting the delicate balance of power in this newly interconnected world.
