Aaron Adams is the father of Nathan "Nate" Adams and the husband of Lily Adams, and the son of Nathaniel and Lucy Loo. His first appearance occurs during an argument with his wife over pudding, a conflict instigated by the Yo-kai Dismarelda. The disagreement is later resolved when the Yo-kai Happierre inspirits the couple, leading them to apologize and reconcile. On another occasion, Aaron and Lily discover Nate and his friends watching a late-night show, though Aaron displays little reaction to the situation. His relationship with his son is average, while he and his wife share a notably affectionate dynamic. This positive relationship is observed by the Yo-kai Whisper to have made Dismarelda envious. In a future timeline where Nate is an adult with children, Aaron is not directly mentioned. It is noted, however, that Nate retains his average personality and haircut after thirty years.
