After 200 years of living in their own bubble, humanity was finally dragged back to Yamani due to their own negligence. Without their knowing, they are returned to the order of life of their ancestors. Humans are back to being slaves who can be enjoyed by all kinds of creatures. One year later, they realized that they were a small part of the humans who lived in that layer of soil, while the rest were still living safely on Earth. The announcement from the Queen awakens the fighting spirit of the old soldiers who want to return to their sins and save humanity. Without being able to realize that all of that is part of the great destruction that will come to them. The battle within the seven layers of hell has finally begun.
A long time ago, when humans were first transferred to Yamani, in the early decades they were completely consumed by the creatures in Yamani. The kidnapping of humans, the most innocent beings in Nirvana, had occurred tens or even thousands of times since that day.
All creatures began to revere humans, considering them the most luxurious meal they had ever tried and wanting to make humans their main source of consumption. Whereas so far, the culture of cannibalism has not something bad and has never been considered excessive to the point where they only want to eat certain races, others are starting to be forgotten.
However, the effects that humans bring are inversely proportional to all kinds of creatures arriving in the subsoil. Especially when one day, they started making special areas for humans, promising them heaven, letting them live in the top layer of soil, the part closest to Nirvana and making them seem close to gods.
