Description
Ugaki is a detective in the Demi-Human Crimes Division, specializing in cases involving succubi and incubi whose abilities risk manipulating others’ free will. He investigates incidents where their innate powers lead to unintended harm or deliberate exploitation, confronting ethical dilemmas when interrogating demis preemptively treated as suspects. This duty weighs heavily on him, particularly when addressing victims who endure harassment only to face societal victim-blaming.

His decades-long bond with Sakie Satō, a succubus math teacher, reflects a paternal dynamic rooted in mutual trust. Having guided her since childhood, Ugaki provided stability surpassing her biological father’s support, even advising her hesitant pursuit of romance with Tetsuo Takahashi. He reassures Sakie despite her miscalculations about Tetsuo’s immunity to her supernatural allure.

Professionally, Ugaki navigates the intersection of law enforcement and demi-human integration, observing how rising social acceptance reduced overall demi crime rates. Succubi-related incidents, however, remain fraught due to their involuntary influence on others. His duties involve proactive dialogue with succubi communities to mitigate risks and uphold public safety—a role he finds both necessary and emotionally draining.

As a mentor to junior detective Kurtz, Ugaki balances authority with camaraderie, coaxing compliance through light bribes like takoyaki while shielding Kurtz’s impulsiveness with stern oversight. This protective instinct mirrors his guardianship of Sakie, underscoring a broader tendency to nurture those under his care.

Past interactions with Sakie hint at his involvement during her struggles with societal rejection tied to her succubus nature. Though specifics remain unspoken, flashbacks imply Ugaki helped her navigate periods of isolation and power-related crises. His discussions with Tetsuo underscore his pragmatic view of societal adaptation, advocating equilibrium between public welfare and demi autonomy.

His surname—combining characters for “eaves/heaven” and “fence”—symbolizes a guardian role defined by vigilance and boundaries, mirroring his dual mandate to protect society while mediating the fragile coexistence between humans and demis.
