Kyutaro is an experienced operative in the criminal underworld, known for his role in coordinating assassination jobs and facilitating interactions between clients and trusted hitmen. He uses his pub as a front for his dealings, managing it as a seemingly mundane establishment while operating a far more dangerous business behind the scenes.

Though little is revealed about his past, it is implied that Kyutaro has been in the business for years and has likely seen the rise and fall of many operatives. His calm demeanor and strategic thinking suggest a deep understanding of how the underworld works and how to survive in it.

He has worked with Kazuki and Rei for a long time, acting as their handler, fixer, and source of information. While he often appears exasperated by their behavior, especially Kazuki’s emotional volatility, he values their skill and loyalty.

Kyutaro is a middle-aged man with a broad, athletic build, neatly combed black hair, and a trim beard or stubble that adds to his rugged charm. He often wears bartender attire a dress shirt, vest, and apron maintaining the illusion of a regular pub owner. His sharp eyes and serious expression give him an air of quiet authority.

Despite his outward professionalism, there is a laid-back quality to his movements, reflecting his experience and comfort within the dual roles he inhabits.

Kyutaro is calm, calculated, and businesslike, rarely letting his emotions interfere with his decisions. He values efficiency, discretion, and control, especially when dealing with unpredictable elements in the criminal world. He often appears cold or indifferent, especially when giving out missions, but his actions reveal a more nuanced personality one that includes concern, loyalty, and subtle protectiveness.

He is particularly aware of the risks Kazuki and Rei take by involving a child like Miri in their lives and voices concern over their declining focus. However, he never outright condemns their choices, instead offering stern advice and occasional quiet support, indicating that he cares more than he lets on.

• The Handler
  Kyutaro’s main role is to coordinate assassination jobs, provide intel, and manage logistics for Kazuki and Rei. He acts as their contact for most of their missions and keeps them informed of targets, conditions, and safe houses when needed. His pub serves as a low-key meeting place where business is discussed discreetly.

• Observer and Advisor
  As Kazuki and Rei’s lives begin to shift with Miri’s arrival, Kyutaro becomes a silent observer of their transformation. He warns them about the dangers of mixing personal life with work but ultimately allows them the freedom to make their own choices. His commentary on their evolving family dynamic serves as a pragmatic counterpoint to the emotional core of the story.

• A Man with Limits
  Despite his composed exterior, Kyutaro is not without lines he won’t cross. When jobs or clients become too volatile, he takes steps to protect those under his care. While he may not be a father figure like Kazuki or Rei, he represents the harsh but steady reality of the underworld they inhabit.
