Eruru

Eruru is a young dragon-clan girl hailing from the ancestral homeland of dragons, sharing a deep childhood bond with Mathew. She joins hero Seiya's party under the humble title of 'luggage carrier,' yet her role proves far more vital — she is the team's dedicated support mage, specializing in speed buffs and magical enhancements. Her past harbors a harrowing secret: she was once fated to be sacrificed in the ritual forging of the world's most powerful holy sword. Rescued by Seiya's timely intervention, Eruru channels that near-tragic experience into relentless self-improvement, ultimately becoming an irreplaceable pillar of strength for her companions.
