Toki resides at the Local Senior Center in a coastal town, sharing her days with fellow seniors Noriko and Yoshie. She crosses paths with the story’s central characters during their visits, notably meeting Sōsuke when he eagerly presents Ponyo—still in fish form—to the elderly group. Toki dismisses the creature as underwhelming, her sharp critique provoking Ponyo to retaliate by spraying her dress with water, which sends Sōsuke scrambling to defuse the tension. When a storm fueled by magical chaos batters the town, Toki and the others briefly receive aid from Lisa, Sōsuke’s mother, who ensures their safety amid the turmoil. Known for her no-nonsense attitude, Toki openly doubts Sōsuke’s tales of Ponyo’s enchantments, even as her peers react with amusement or intrigue. Yet a quieter exchange reveals unexpected warmth: Sōsuke gifts her a meticulously crafted paper replica of his father’s ship, a small but earnest overture that softens their earlier friction. Her presence weaves through pivotal moments, such as a chaotic chase where Sōsuke and Ponyo vault past her, leaving her comically drenched—a playful nod to the ripple effects of magic. Through these interactions, Toki’s steadfast pragmatism and occasional candor underscore the story’s themes of generational bonds and communal endurance, anchoring her as a subtle yet enduring fixture in the narrative’s tapestry.
