From Madurai, Arjun is the sole breadwinner who uses a blunt, often brutal sense of justice to curb crime. He partners with Sophia to crack the case and confront the criminal network, facing demotion and higher-stakes danger when his family is threatened. Arjun's moral code is tested as he balances duty with empathy for those he loves.

Sophia is Arjun's cybercrime-savvy partner who helps uncover the network's use of the dark web and stolen bikes. She provides technological leverage and sharp investigative instincts, aiding the police with digital forensics and strategic planning. Her collaboration with Arjun strengthens the team’s ability to connect disparate crimes.

The mastermind behind Satan's Slaves, Naren indoctrinates unemployed graduates and orchestrates the gang's operations from behind a veneer of legitimacy. He is cunning, ruthless, and capable of manipulating others to achieve his aims, including using Kutty to expand his reach. His charisma masks a calculated, dangerous ideology.

Arjun's unemployed younger brother, Kutty is humiliated by in-laws and drawn into Wolfranga's orbit. His trajectory shows the vulnerability of youth to criminal influence, and his eventual conflicting loyalties create personal and familial turmoil. Kutty's path underscores the film's themes of belonging and repercussions.

Arjun's mother, Lakshmi's unwavering care anchors the household. Her lines of love and sacrifice motivate Arjun's actions and provide emotional grounding amid the chaos of the investigation. Her presence highlights the human cost of crime and the hope for safety in the family.

Sarah is Wolfranga's girlfriend whose fate intersects with the protagonists' mission. Her role underscores the personal casualties of the gang's war on the city and the high stakes of loyalty within the criminal circle. Her arc contributes to the film's emotional intensity.

The city commissioner who entrusts the case to Arjun, Vijayakumar embodies the political and bureaucratic pressures that frame the investigation. His leadership is tested by the case's complexities and the public demand for results. He represents the expectations of authority in a crime-heavy metropolis.

A figure of power who is secretly aligned with Wolfranga, Rajangam undermines the investigation from within. His betrayal illustrates the pervasive corruption within the system. His actions escalate the stakes and complicate Arjun's pursuit of the truth.

A high-ranking officer who also serves Wolfranga's interests, Arasu contributes to the web of complicity that hinders justice. His presence highlights the theme that power can corrupt the enforcement apparatus. Arasu's moves push Arjun to push harder for accountability.
