Known as "Keita's Father" in Japanese media and Aaron Adams in localizations, he is married to Lily Adams and father to Nate Adams (Keita Amano). Aaron presents as a calm, caring salaryman dedicated to his family. Secretly exceptional at work, a promotion in *Yo-kai Watch 3* required relocating the family to BBQ (St. Peanutsburg). His apparent fluency in the local dialect stemmed from being inspirited by the Merican Yo-kai, Lionguist. After Nate befriended Lionguist, Aaron lost this fluency, struggled with communication, and was ultimately recalled to Springdale. In the anime, he debuted in Episode 001 arguing with Lily over yogurt while inspirited by Dismarelda, a Yo-kai feeding on marital discord; reconciliation came with Happierre's inspiration. Episode 006 showed minimal reaction to Nate and friends watching a late show. His devotion was evident in Episode 090 when he resisted the Yo-kai Lazy Sundae's influence to abandon his family for his boss. Within the games, when Nate is the protagonist, Aaron serves as the player's father. In *Yo-kai Watch* Chapter 2, he argued with Lily over chores due to Dismarelda. Nate defeated Dismarelda with Jibanyan and reunited her with Happierre, prompting Aaron and Lily to apologize, commit to mutual respect, and share a family dinner. His role diminishes if Katie is the protagonist, though he remains present at Nate's house. The BBQ job transfer is a key element in *Yo-kai Watch 3*. His parents are Nathaniel and Lucy Loo. His relationship with Nate is described as average compared to Lily's more emotional interactions. Whisper noted that Dismarelda's initial envy stemmed from Aaron and Lily's loving marriage.
