Description
Riko is a 12-year-old orphan raised at Belchero Orphanage in Orth, the town encircling the immense Abyss. Her mother, the legendary White Whistle cave raider Lyza, vanished on a final dive to the Abyss's depths when Riko was two. Riko's own birth occurred under extraordinary circumstances within the Abyss's fourth layer; initially stillborn, she was revived using the Curse-Warding Box relic. This event left her with chronic poor eyesight, requiring glasses with crystal lenses to prevent headaches. Her identity as Lyza's daughter was kept secret for protection. Studying cave raiding techniques, she earned a Red Whistle, permitting independent exploration of the uppermost layers. Her journey commenced upon discovering a note from Lyza stating, "At the Netherworld's bottom, I'll be waiting," alongside a sketch resembling Reg, a robotic boy she later found. This prompted her secret descent into the Abyss with Reg, aiming to become a White Whistle and reunite with her mother.
She possesses blonde hair, typically in long pigtails, green eyes, and signature square glasses. Her appearance changes during her journey; in the sixth layer's Village of Iruburu, she trades her hair for "Value," resulting in a short cut mirroring her father Torka's style. A prominent scar on her left arm marks an emergency amputation to save her from venom in the fourth layer, leaving limited sensation. A smaller scar on her right cheek resulted from the Abyss's curse in the fifth layer. Her standard delving attire includes a delver jacket, leotard, stockings, climbing harness, and helmet, supplemented by a green overcoat and earmuffs in the fifth layer. Casual outfits feature a white dress with a leather seat and multicolored boots.
Her personality blends energetic curiosity with resilience. Under pressure, she exhibits a rational, observant mindset, devising survival strategies or documenting Abyss ecology. Her enthusiasm for exploration often leads to impulsive actions like tasting unknown substances or handling relics without caution. She prioritizes her goal of reaching the Abyss's bottom over conventional morality, rationalizing antagonists' actions if they align with her view of true adventure. Despite physical fragility, she displays mental fortitude, enduring extreme amputation pain without losing composure. She forges strong bonds, showing loyalty and caretaking tendencies, notably through her cooking skills, crafting palatable meals from Abyss flora and fauna.
Her abilities focus on knowledge and adaptability. She memorized extensive relic catalogs and Abyss lore, enabling identification of artifacts, creatures, and hazards, aiding navigation and problem-solving like using cave raider whistles against sound-sensitive monsters. After losing mobility in her left hand, she relies on a support device crafted by Nanachi. Her culinary ingenuity sustains the group, though consuming risky ingredients often endangers her. Quick decision-making helps her survive lethal situations, like directing Reg during the amputation or leveraging the Curse-Warding Box when poisoned.
Key relationships define her journey. Reg serves as her primary protector; she named him after a childhood dog and studies his robotic capabilities. Nanachi joins after healing her arm, providing medical expertise and deeper layer guidance. In the fifth layer, she befriends Prushka, Bondrewd's adoptive daughter, whose transformation into a White Whistle enables Riko's descent. Her reverence for Lyza evolves from familial longing to ideological emulation, though she gradually prioritizes her own curiosity over merely finding her mother. Interactions with cave raiders like Ozen or Hablog reveal surprise at her determination despite her youth.
Her development reflects increasing physical and ideological sacrifices. Early layers establish her determination, but the fourth layer marks a turning point: surviving the amputation hardens her resolve, and Nanachi's aid solidifies their trio. In the fifth layer, she receives Lyza's relic, Blaze Reap, though combat limitations persist. Witnessing the destruction of Lyza's favorite eternal fortune flower field symbolizes separation from her mother's legacy. Prushka's sacrifice—resulting in Riko's White Whistle—cements her irreversible last dive, as ascending would now be fatal. By the sixth layer, trading her hair for "Value" signifies further bodily compromise. Across all media, her motivation shifts from seeking Lyza to embracing the Abyss's mysteries for their own sake, affirming her identity as an autonomous adventurer.
