In Tokyo, I draw cards and become a big demon

Uesugi Tetsu traveled to Japan and discovered that he could draw cards to transform into demons and ghost stories in historical legends.
Moreover, all the evil spirits and monsters in the world can turn into ashes after death, providing assistance for his next card drawing.
【Laughing Prajna】
[Onmyoji's evaluation: This little demon scares children for fun. His only strength is his physical body. Not worth worrying about.]

【Hundred Eyes Demon】
[Onmyoji's evaluation: He has a hundred eyes, and although his illusions and dreams can capture people's imaginations, his physique is not strong enough. He poses little threat.]

【Guhuo Bird】
[Onmyoji's evaluation: A nine-headed monster whose fire can burn everything. It can transform into a human and enter the world! It poses a very high threat!]

[Onmyoji's evaluation: ...]
The ordinary world that fell into the abyss thousands of years ago has surfaced and merged with the human world again. This was originally a golden age of demons and ghost stories.
The hegemons of the times since ancient times are eager to try - the Twelve Crowns are ordered to travel the world; Shuten-doji brings thousands of miles of rivers and mountains; Qingxuande tries to set off the Night Parade of One Hundred Demons again; the Warring States Daimyo raise their flags to mobilize the army...
Unfortunately, Uesugi Che, who also possessed numerous demonic talents, opened his eyes and separated the yin and yang.
He shook his head and sighed:
"You only know how powerful I am now."
"But I don't know——"
"How many good brothers turned into a handful of ashes and fell on the road I came here."
