Maroro appears as a supporting character in Utawarerumono: The False Faces. He is a nobleman and scholar who serves as the resident scribe and magician within Ukon's entourage. Physically, he is depicted as frail and often behaves in a comical manner, with a flamboyant appearance marked by ornate clothing and heavy white makeup that evokes the style of a court aristocrat. He speaks in an affected, archaic manner that further emphasizes his pretentious yet endearing personality.

His magical abilities are distinctive and tied to performance: Maroro must execute a lengthy incantation accompanied by a matching dance in order to cast his spells. This peculiar method, while seemingly absurd to onlookers, produces powerful area-of-effect fire magic. Despite his theatrical style, Maroro is genuinely knowledgeable and takes his role as a scholar seriously. His motivations primarily revolve around loyalty to Ukon, whom he accompanies faithfully, and later, after being saved by the protagonist Haku, he develops a strong attachment and gratitude toward Haku.

Within the story, Maroro serves as both comic relief and a source of magical support during battles. He interacts closely with Ukon, Haku, and other members of the group, often providing commentary or getting swept up in the group's adventures. His development is subtle; though he remains largely defined by his eccentricities, he occasionally demonstrates sincerity and courage when his friends are in danger. Maroro reappears in the sequel Utawarerumono: Futari no Hakuoro, continuing his role as a loyal retainer and practitioner of fire magic.
