Seven Layers of Hell
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.

The seven gates lead to the same world that Tirta had previously traversed. Everything points to L-02 at the end of L-03; actually, it's quite easy to get there on a normal day, though they still can't reach the castle at L-02 without permission from the Queen. However, because this was the recruitment period for Candrasa's men, they had changed their route to L-02 through the gates in L-03.
They wouldn't be able to get to L-02 through anywhere but the seven-gate passage. All areas above and below the gate have been marked; they have everything under control. The only safe area on L-03 now is in the Hanging Gardens, where they have come and been rounded up.
Because once they enter the gate, they will not be able to get out again. The choice is to go inside the walls and win or be killed.
