Raelza is a warrior clad in heavy armor and wielding a large broadsword designed with holes for back-carrying. She possesses long dark brown hair, amber eyes, and a facial scar from a past goblin encounter that fuels her self-consciousness. Despite projecting a stoic and intimidating presence, Raelza is fundamentally shy and timid, easily flustered in emotionally exposing situations, especially around Saitou. An intense fear of long, slimy creatures like eels severely hinders her combat effectiveness against such foes. Orphaned young while living in the wilderness, Raelza survived with a wolf pack until the mage Morlock discovered and adopted her. This forged a deep, familial bond; she regards Morlock as her father despite frequently managing his dementia-induced scatterbrained behavior. She later formed an adventuring party with Morlock and the fairy Lafanpan, which Saitou joined after arriving in their world. As the party's primary tank, Raelza specializes in defensive combat using her armor and broadsword, though she is also proficient with daggers and hand-to-hand fighting. Her battle reliability starkly contrasts with her vulnerability during equipment mishaps, such as the extreme embarrassment when metal-eating slimes disintegrated her armor. Saitou subsequently enhanced her gauntlets with concealed blades for emergencies, increasing her versatility. Raelza harbors a romantic interest in Saitou but struggles to express her feelings due to shyness, often blushing and covertly watching his interactions with other women. Jealousy surfaces when figures like Mevena or Gible show interest in him, sometimes prompting protective or possessive reactions. Her self-consciousness extends to her femininity, fearing Saitou might not see her as a woman, leading her to avoid removing her armor in his presence unlike before. Her character evolves from reserved warrior to one more openly reliant on her party, particularly Saitou, whose critical support role became evident during his absence due to illness. She trains Saitou in basic combat, aiding his transition from non-combatant to capable adventurer. Private discoveries about Saitou's physical attributes, such as his "half-Maderaca" size, cause persistent flustered reactions she keeps to herself.
