Mr. and Mrs. Asami
Tatsuya's father Wateru Asami who is the chairman of the largest business corporation in Japan known as the Asami Group. Wataru is a cold-hearted individual who was only concerned with business matters and tried to control Tatsuya's life believing that Tatsuya was only meant to follow in his footsteps. Wataru also set the City Guardians as a means of protecting the city from the Londarz Family. He eventually found out that his son was TimeRed when his mask was broken during battle. Wataru eventually agreed to allow Naoto Takizawa to become the leader of the City Guardians after he gained control of the V-Rex and tried to recruit the other Timerangers into the City Guardians but was turned down. Eventually Wataru was hospitalized during Gien's attack on the City Guardian headquarters. In the finale he decides to allow for Tatsuya to live his own life.

Domon tried to set up Honami with Ayase, and in the end Honami's misunderstanding was cleared up when Domon was willing to protect her from a bomb. They started dating by the end of the series, Homani has a child named Domon Junior but she never told the father.
