Senichi Sasaki

Senichi Sasaki, Chiho's father, holds the rank of police lieutenant at the Nishi-Shinjuku Station. He was the very first human being the Demon King and his subordinate encountered upon arriving on Earth, and he willingly offered them assistance when the two were injured. Though an ordinary human, his warm and conscientious nature made him an indispensable guiding presence during the Demon King's initial days in the human world, and he remains a quietly supportive figure in his daughter's life.
