Movie
Description
Nat, a Red Whistle delver residing at Belchero Orphanage, shares quarters with fellow orphans Shiggy and Kiyui. Born in the Wharf Quarter’s poverty, he found refuge at the orphanage following his older sister’s death, which stranded him on the streets. His blunt exterior veils a deeply caring core, often concealing vulnerabilities through teasing or irritation—particularly toward Riko, whose choice to descend into the Abyss he fiercely resists, torn between fear for her safety and unspoken affection.

Aspiring to earn his Moon Whistle rank, Nat strives to establish a sanctuary for Wharf Quarter children, fueling his relentless drive as a delver. Though he views himself as ordinary next to prodigies like Riko, his resilience shines through as he mentors novice delvers and uplifts companions during trials, such as steadying Dorothea upon discovering a lost peer’s remnants.

Nat plays key roles in critical moments: shielding Reg’s mechanical identity by crafting a cover story drawn from his past, and smuggling Riko through Wharf slums for her clandestine departure. Their parting strains his emotional resolve, leaving him tearfully resigned to their separation yet skeptical of promised letters from the Abyss’s unfathomable depths.

His bond with Riko weaves camaraderie with protective friction, clashing against her recklessness yet rescuing her from a Crimson Splitjaw’s jaws. Beyond Riko, he channels loyalty into rallying fellow orphans—urging support for Tiare and orchestrating communal joys like the Birth Festival, though his mischief often draws humorous scoldings.

As years pass, Nat retrieves Riko’s inaugural mail balloon from the Abyss’s upper strata—a fragile token of their bond. Subsequent silences reinforce the chasm between their worlds. While advancing through deeper layers himself, he trails Riko’s team, pledging to bridge the gap without abandoning his orphanage charges.

Nat’s journey orbits perseverance and muted heartache, honoring his sister through his orphanage dream. Though blunt edges and fleeting jealousies spark tensions, his bedrock compassion and steadfast commitment cement him as the narrative’s resilient anchor.
