Ritos Tortilla is the younger twin sister operating the Tortilla Company in Ert'Aria with Salsa. Their business focuses on acquiring rare crystals valued for Ale energy, obtained during explorations where they often cross paths with the Oasis adventurer clan.

A calm, reserved exterior cloaks Ritos's mischievous nature. She routinely engineers situations to Salsa's detriment by withholding critical plan details, leaving Salsa facing blame, traps, or injuries while Ritos escapes unscathed. This manipulation includes falsely accusing Salsa of mishaps and twisting Salsa's words when retelling events.

Ritos exploits Salsa's romantic feelings for Leicester Maycraft. She deliberately employs suggestive language and innuendo around Leicester to provoke reactions from Salsa and others, despite her own lack of romantic interest. Notably, she arranges private meetings between Salsa and Leicester, hinting at underlying care for her sister's happiness.

Her comedic role frequently involves the "boke and tsukkomi" routine with Salsa, Ritos acting as the deadpan instigator of misunderstandings. Physical comedy unfolds when her deliberately delayed hazard warnings trigger mishaps, sending Salsa and their golem companion tumbling into swamps or off cliffs.

Ritos contributed to the golem's programming by installing Leicester's supportive personality traits, enabling it to comfort characters like Chelsea Arcot in distress. This programming also causes the golem to blush in Leicester's presence.

Her narrative prominence peaks during a dedicated episode focused on the Tortilla sisters and their golem, featuring a special opening theme specific to their storyline.
