Shirou Hanada

Shirou Hanada appears from the second volume, with his character illustration added only in the fourth.

He serves as a subordinate of Tomoe Minai and is a contemporary of Shingo Fujita.

His real name is Shirou Takiguchi.

In the past, Shirou lost his only family—his older brother—when he was shot dead by the father of Tomoe Minai and Minai Madoka during a criminal case.

Left with nowhere to go, Shirou was later taken in by the Minister of Welfare, Chiba, who led him into the underworld.

Shirou is driven by a burning hostility toward the Minai family, blaming them for his brother's death.

This hatred is especially directed at Tomoe Minai, who followed his father's path to become a detective and survived both the fire and tragedy.

Despite his anger, his time undercover in the First Investigation Division has left Shirou with complicated feelings.

Working alongside Tomoe Minai and Shingo Fujita, he experienced a sense of fulfillment and camaraderie he hadn't anticipated.

Shirou Hanada is the direct perpetrator behind several pivotal events.

He murdered the parents of Tomoe Minai and Minai Madoka.

He also abducted Nagisa Ozaki, leading directly to her tragic death.

These acts were fueled by a desire for revenge and shaped by the trauma of his past.

Though rage drives his actions, the normalcy and sense of belonging he tasted while embedded with the detectives lingers.

Shirou is haunted by the contrast between his vengeful quest and the relationships he formed while undercover.

His inner turmoil makes him both a dangerous enemy and a sympathetic, multi-layered character.

Shirou Hanada is intrinsically linked to Tomoe Minai and Shingo Fujita through both occupation and fate.

His vendetta against the Minai family comes from deeply personal tragedy.

Ironically, the time spent working as their colleague brought him moments of warmth and meaning, complicating his mission of revenge.
