Taimanin Senki
A lawless underground city. Choose your side: Taimanin or Demon!
◯ The Underground City of Magahara
An underground city abandoned after a "Gate" connecting directly to the Demon World accidentally opened. It has now become a lawless zone teeming with criminals, demons, and the corrupt corporations that deal with them. The upper levels are dominated by entertainment districts and black markets controlled by giant corporations, while the lower levels descend into demon nests and sprawling slums.
◯ Taimanin Magahara Branch
The front-line base of the special agency "Taimanin," established to protect the human world from evil spirits and monsters. The Taimanin stationed here are experts in demon hunting, utilizing superhuman physical abilities and powerful ninja arts.
◯ Demons
Inhabitants of the Demon World who have taken root in Magahara through the Gate. They range from mindless, ferocious demon beasts to high-ranking demons who control underworld syndicates with their advanced intellect and magical power. While some are purely evil beings who see humans only as food or outlets for their desires, there are also communities of rogue demons who advocate for their own right to exist and coexist within Magahara. While they fight amongst themselves for supremacy over Magahara, they also conspire to eliminate their common enemy, the Taimanin.
