OVA
Description
Kazunobu Chiba serves as a police detective in the Tokyo Metropolitan Police Department’s Second Violent Crimes Investigative Division, Section 3, balancing routine tasks like gathering evidence and briefing superiors with occasional independent casework. His stout build and sharp, tousled black hair frequently punctuate scenes with comedic undertones.

A Teitan Elementary alumnus, Chiba co-created the tokusatsu film *Kamen Baiya* as part of the broadcasting committee, fostering a bond with childhood friend Naeko Miike. Before her family relocated, he confessed his feelings via a love letter. Years later, aided by the Detective Boys, he unearthed Naeko’s covert reply on a VHS tape in the school storage room—a sweat-revealed message affirming her reciprocated crush. Unaware of her identity during their adult reunions, he inadvertently inspired her career as a traffic officer through his unwavering respect for the law.

Chiba’s jovial demeanor masks a rigid ethical compass, prioritizing legal procedures over personal ease. His fondness for burgers and sodas pairs with a tokusatsu figurine collection (*Kamen Yaiba*, *Gomera*) and a meticulous habit of rewinding VHS tapes, inherited from his brother’s video-store tenure. He nurtures a steadfast friendship with Wataru Takagi, urging him to pursue Miwako Sato while sidestepping divisive office politics like Shiratori’s romantic meddling.

In *The Miracle of Excalibur* OVA, Chiba aids Takagi in probing a jewel heist, tracing a buried baseball bat initially linked to the crime. Conan later exposes the bat as part of an unrelated motivational ploy for a young athlete, underscoring Chiba’s methodical approach to legwork and deference to sharper deductive minds.

His narrative arc weaves reliability and protocol-driven diligence with gradual professional autonomy, transitioning from background roles to leading investigations. Lingering romantic tension with Naeko echoes their shared past, while childhood passions for tokusatsu and broadcasting subtly shape his investigative instincts and personal pursuits.
