In the games
Jason Forester first appeared in Yo-kai Watch. If Katie is picked as the main character, Jason will be the player's father.
In the second chapter, when Katie returns home after first acquiring the Yo-kai Watch and meeting Whisper, she finds his parents having an argument over the housework. Rebecca accuses her husband of not helping her with it at all, leaving her to do everything.
Katie soon discovers the reason for their sudden irritation at one another is Dismeralda, who has inspirited both of them.
After being freed from the Yo-kai's influence, Katie's parents apologize for their behavior, promising to help and respect each other more from now on, and the chapter ends with the entire family preparing dinner together.
If Nate is picked as the main character, Jason's role is much smaller, but he can still be found in Katie's house and can be talked to.
Katie is his daughter.
Rebecca is his wife. They're shown to be very affectionate with one another, usually. Whisper notes that they're so loving, its no wonder Dismarelda became envious of them.
