Walker is
Goh's father. His wife is
Camille. He lives on the 7th floor of an apartment complex in the Kanto region within a bus journey of the Cerise Laboratory. His mother-in-law,
Halta, lives with him.
Camille is a programmer and
Walker is a systems engineer. They work on their own business called Go-Go Systems and whenever there's a systems emergency, their expertise is in high demand. They often stay at the office late, so
Goh can't just show up at home out of the blue. He makes sure to call his parents ahead of time.
