Mao

Mrs. Mao is an inhabitant of Elmo Village.

She's the owner of the Maple Leaf Inn, a hot spring hotel that is the village's main tourist attraction, and she's the closest thing Elmo has to a village elder. She was born in a country to the east, but she and her family moved to Liberl when she was very young and she presumably met Professor Russell soon afterwards, as Mrs. Mao mentions she and Russell have been friends since they were "knee-high to a grasshopper".
