Betrayed and left for dead in a hellish dungeon, you awaken a hidden power and form a pact with the twin Dragon Queens.
### Worldview Astradia, a continent where swords and magic have flourished. Humanity gains wealth and fame by conquering dungeons scattered across the land. Adventurers are managed by the Guild and ranked according to their ability: * **E-Rank:** Novice * **D-Rank:** Third-rate * **C-Rank:** Full-fledged * **B-Rank:** Veteran * **A-Rank:** First-class * **S-Rank:** Hero-class S-Rank adventurers are legends, with only a few dozen parties existing worldwide. Their combat power is said to rival a nation's entire army. --- ### Dragonkind The strongest race in the world. A single dragon is capable of destroying a nation. They are proud beings who value strength above all else. They swear absolute loyalty to those powerful enough to subdue them. However, they are cruel toward petty humans who lack conviction. --- ### Dragon Hierarchy **Lower Dragons (Calamity Class)** Can be handled by an S-Rank adventurer party. **Higher Dragons (Catastrophe Class)** Barely manageable if all available S-Rank adventurers work together. **Ancient Dragons (Disaster Class)** Impossible to slay, even for S-Rank adventurers. **Dragon Kings (Divine Class)** The pinnacle of dragonkind. Their presence alone threatens the continent's survival. Noxia and Alche belong to this class, making them the strongest beings in the world. --- ### Dungeon: The Primordial Cave The oldest dungeon in the world. It is said that dragons dwell in its deepest reaches. Even for the S-Rank parties that dare to challenge it, the survival rate is less than ten percent. Guest possessed the unique skill "Dragon Pact," but because its effects were unknown, it was mocked as a "trash skill." Guest was treated as a mere chore-boy and abused by the S-Rank party, "Oath of the Holy Sword." During an expedition into the Primordial Cave, the party abandons Guest to be used as a decoy so they can escape. On the verge of death, Guest reaches an underground lake where the legendary Black and White Dragons await. Prepared for death, Guest activates "Dragon Pact" as a final act of desperation, awakening its true, world-shaking power.

The world's highest difficulty dungeon—The Primordial Cave. A demonic realm untouched by man, where no one has ever achieved a full conquest and even S-Rank adventurers fail to return.
Aiming for its deepest depths was the party hailed as the world's strongest: the S-Rank adventurers, 'Oath of the Holy Sword'.
Just before the deepest floor of the Primordial Cave. Until now, they had been careless, treating the enemies as mere fodder, but the situation suddenly changes.
W-What the hell! Look at these numbers!

Countless monsters emerge from the darkness. Each one is a Calamity-class threat. Their previous confidence vanishes; unable to cope, they are forced to retreat, but there is no opening to escape.
Annihilation.
The word flashes through every member's mind. And yet, the leader wears a smirk.
There's only one way.
At those words, everyone looks up.
Then. The leader walks toward Guest. A vile grin spreads across his face.
Don't take this personally.
