Lily Adams, mother of Nathan Adams, has brown eyes and long brown hair, usually seen wearing glasses. Her typical outfit consists of an orange scarf with white polka dots, a pale yellow rolled-up long-sleeve shirt, light gray denim shorts, dark brown tights, and yellow ballet shoes. She wears an apron for housework and a purple leotard with yellow leggings and lavender leg warmers for workouts. Her personality blends kindness with strict discipline. She shows devotion by cleaning, buying rare snacks, or baking homemade cookies for Nathan. Disobedience, however, triggers intense anger, humorously called "Monster Mom" in the Yo-kai Medallium. Nathan once claimed he'd prefer confronting the Oni Yo-kai Gargaros over his angered mother. Despite this, she maintains a loving and soft side. In the first game, she cooks meals for Nathan when interacted with during afternoon hours. A key story involves her arguing with husband Aaron Adams over neglected housework, later revealed to be caused by Yo-kai Dismeralda. After Nathan defeats Dismeralda with Jibanyan's help, and Aaron is inspirited by Happierre, they reconcile, commit to mutual respect, and prepare dinner together. If Katie Forester is the player, Lily remains in Nathan's house with reduced interaction. Her role continues: In *Yo-kai Watch 2*, she argues with Aaron over Spirit or Soul Donuts, winning in *Bony Spirit*. This conflict becomes optional in *Psychic Specters*. She still cooks afternoon meals. In *Yo-kai Watch 3*, she moves with the family to St. Peanutsburg, loses her glasses (later found on a fire hydrant), and prepares a celebratory meal for their new home. In the anime (debut EP001), she argues with Aaron over yogurt due to Dismeralda, resolving when Happierre inspirits them into apology. Later episodes show her discipline: EP004 – Orders Nathan to clean his room and scolds disobedience; EP018 – Tasks Nathan with awaiting a delivery, becoming enraged when he leaves and returns chased by Gargaros; EP062 – Repeats the delivery instruction, warning against prior mistakes, and plans to ground him after he disobeys again. Her relationships reflect care and authority. With Nathan, frustration over disobedience mixes with underlying affection; he calls her his "best mom ever" (EP003, EP038). With Aaron, their bond is typically affectionate, noted by Whisper as so loving it incited Dismeralda’s envy. In the *Shadowside* timeline (30 years later), she is Nathan's mother, though her status is unspecified. Nathan and Katie mention Aaron in SS044, but not Lily. Trivia notes her similarity to *Doraemon*'s Tamako Nobi as a glasses-wearing, strict yet loving mother. Her Japanese name, "ケータの母" (Keita no Haha), translates to "Keita's Mother"; "Lily Adams" is the English adaptation.
