Samon Takamizawa is the chef and proprietor of Trattoria Samon, a popular Italian restaurant situated next to the Asagiri household in the lunar-Earth diplomatic city of Mitsurugasaki. His cooking keeps the restaurant consistently popular. He employs his daughter Natsuki Takamizawa, his son Jin Takamizawa, and Tatsuya Asagiri as waitstaff. Samon runs his staff fairly and considerately, though he maintains a stricter approach with his son Jin, deducting the cost of any restaurant damages from Jin's salary.

With brown hair and brown eyes, Samon sports glasses and a hat fitting his role as an adult restaurateur. His family operates the establishment together; Natsuki works alongside Tatsuya and Princess Feena Fam Earthlight during Feena's homestay on Earth. The trattoria serves as a recurring setting where interpersonal dynamics unfold among the staff and patrons.
