Kaval commands leadership of an adventurer party as a frontline fighter, balancing workplace politeness with habitual grumbling—even in the presence of superiors. His authority derives less from tactical acumen than his magnetic presence and striking looks, traits that mask a penchant for recklessness. This impulsiveness routinely escalates tensions, his curiosity likened to "prodding hornets’ nests" to provoke unpredictable outcomes that multiply the party’s skirmishes with monsters. Though publicly branded an adventurer, he secretly safeguards Elyun Grimwald as an undercover protector. His ochre hair falls to medium length, framing green eyes and a lean build typical of his late-twenties youth. Assigned to a three-member unit probing the vanishing of a sealed cave’s ancient entity, Kaval crosses paths with Rimuru during the investigation. While external forces repeatedly rescue the party from escalating dangers, his own combat engagements remain peripheral to pivotal narrative moments dominated by allies.
