Description
Keisuke Sudou is a central character who holds a supervisory position in a professional workplace, where his strict management style and exceptionally high expectations have earned him the intimidating nickname of demon boss. He is 31 years old and stands 180 centimeters tall. Despite his fearsome reputation at the office, Sudou possesses a complex personality that reveals unexpected warmth and kindness in his personal life.

In his role as a superior, Sudou is portrayed as someone who is extremely earnest and dedicated to his work. This serious approach to responsibility defines his character, as he commits himself wholly to any task he undertakes. However, this professional rigor forms a notable contrast with his private conduct. This duality becomes apparent when he encounters his subordinate, Saki Watase, in a vulnerable state after a company drinking party. Demonstrating a sense of duty that extends beyond office hours, he escorts the intoxicated Saki home safely, an act that sets the stage for their personal relationship.

Sudous motivations are deeply tied to his sense of dedication and a growing personal interest in Saki. When he discovers she is participating in a part-time job testing XL-sized condoms to help with financial difficulties, he does not react with judgment. Instead, he reveals his own physical compatibility with the products and offers his assistance with the evaluation process. This offer, which blends practical help with a clear romantic and physical attraction, showcases his proactive and possessive nature. He becomes invested not just in the product testing but in Saki herself, approaching their intimate relationship with the same thoroughness he applies to his career.

Within the storys narrative, Sudou serves as the primary love interest and a catalyst for the plot. His role involves navigating the transition from a professional superior to a romantic partner. The relationship faces external challenges, particularly with the arrival of a rival named Riku Narita, who also develops an interest in Saki. This creates a competitive dynamic that tests Sudous resolve and possessiveness. Throughout these personal developments, however, his professional competence remains consistently high, and his core personality traits of strictness and dedication do not fundamentally alter. The story shows that beneath his harsh exterior lies a person who is capable of deep commitment and, in an ironic twist, proves to be genuinely kind and supportive.

Keisuke Sudou possesses several notable abilities and traits. He specializes in cooking, indicating a domestic skill that contrasts with his demanding professional persona. His physical stature is a key aspect of his character, as his XL size is not just a personal attribute but a plot point that directly facilitates the central premise. His most defining ability, however, is his meticulous nature. Whether managing a team or participating in Sakis product testing assignment, he applies a level of detailed scrutiny and earnest effort that defines all his actions.
