A 29-year-old Heavy Warrior. A man whose primary weapon is a greatshield nearly as tall as he is, specializing in a defensive combat style focused on holding the front line. He possesses a naturally resilient body and high magic resistance, though his offensive power is not exceptional.

He has a boisterous personality and serves as the party's mood maker, loudly encouraging his comrades on the battlefield. A straightforward man who defines himself as a wall rather than a strategist. He never shows pain or fear, yet he possesses the hidden grit to break his defensive formation and charge forward when his allies are in danger.

A 21-year-old Hunter. A woman who is a master of precision shooting with her longbow. She can imbue arrows with mana, freely controlling their trajectory and penetration, primarily using the water element. A calm and collected observer with excellent scouting and stealth skills, she can accurately pinpoint enemy locations even in the darkness of the cave. While weak in close-quarters combat, she fires the decisive shots that shift the tide of battle from high ground or blind spots.

A woman of few words and a realist who views situations objectively without showing emotion, though her trust in her comrades is unwavering.

A 22-year-old Mage. A brilliant woman with a researcher's temperament specializing in ancient magic. She possesses advanced chanting techniques that allow for simultaneous multi-elemental control, combining water, lightning, and fire as the situation demands. While her mana capacity is nation-class, her true strength lies in her ability to analyze structures and reconstruct spell formulas. In battle, she handles wide-area annihilation and barrier support, but her defenses are thin during incantations.

Intellectual and rational. She prioritizes theory over emotion, but her sense of responsibility to protect her friends is stronger than anyone's.

The Azure Crystal Overlord Dragon, Azura-Gladius, is a calamity-class entity sealed in the deepest part of the northern mountains. Covered in blue crystal scales, it houses a mana core in its chest. Upon awakening, vast amounts of mana leak from the core and crystallize within the cave, from which monsters are autonomously generated. Its roar shakes space itself, and it possesses extremely high resistance to both physical and magical attacks, along with regenerative abilities. It has no concept of good or evil; it is a natural phenomenon that disrupts the surrounding balance simply by existing. Total subjugation is theoretically possible, but the realistic success rate is extremely low.
