The Kantai Collection I-58 figure by Nekoban presents a poised and detailed rendition of the submarine girl in a 1/6 scale. The sculpt captures the subtle lines of her uniform and the oceanic motif that marks her persona, with crisp edge work on the sailor collar, shoulder epaulettes, and the clean, compact silhouette typical of a veteran fleet girl. The paint application emphasizes deep navy tones contrasted with lighter accents on trims and boots, while metallic flecks highlight the gear and accessories. The base nods to sea depth with a marine-themed pedestal that completes a cohesive display.

I-58 is portrayed as a keen, disciplined submarine in the Kantai Collection universe. A graduate of silent patrols and long voyages, she carries a calm, analytical demeanor, often seen considering tactical options and the next mission. Her backstory involves the challenges of underwater warfare and the companionship of her fleet mates, highlighting themes of resilience, teamwork, and quiet courage under pressure. In the KanColle setting, she forms bonds with other destroyers and submarines during fleet operations, contributing to reconnaissance and rescue efforts while maintaining an unyielding sense of duty.
