Stuck on the 27th floor with no way out, Lilly and the rest of the party are forced to endure an "adventure" that has been thrust upon them in the sudden absence of their leader. Meanwhile, Bell and Lyu have found themselves on the 37th floor after becoming separated from the others. Alone, without support, and unsure of what to do, will they be able to make it out alive of the deepest floor Bell has ever set foot in?
The prophecy of despair continues...
When an unprecedented calamity on the twenty-seventh floor leaves Bell and Lyu stranded, Bell's party needs to keep fighting without him. With their route to the surface lost and Hestia Familia's captain missing in action, Lilly must take command to ensure they all make it home alive. Ten floors below, Bell and Lyu are injured and alone, forced to struggle against the harshest challenge the Dungeon has to offer, which puts their very lives on the line. Bell has never been this deep down before nor completely unprepared, meaning Lyu's knowledge and strength are essential to their survival. However, the forlorn elf finds herself standing on the border between life and death, bound by her past, remembering once again exactly how her devotion to justice died so many years ago...
