Ariel

Ariel may appear as a young girl, but beneath that guise lies the founding ancestor of all spider-type monsters and the current Demon Lord—an entity known as the world's oldest divine beast. Once an adversary who hunted the protagonist to protect her kin, she underwent a profound transformation through exposure to the protagonist's parallel-mind fusion, emerging as a bold and indomitable ally. Together, they now pursue a shared mission: to topple the arch-nemesis Potimas and liberate the goddess Sariel.
