She is Flan's grandmother. Despite her caring greatly for him, Flan callously commented that she made awful bento lunches.
Flan's grandmother appears to be very kind, as she offered to give Mammon milk and dutifully cares for her grandson Flan.
Flan's grandmother is elderly, her hair having gone gray, which she pulls into a bun. She is seen wearing a long, brown dress. She has wrinkles on her face due to age and is rather short.
