I randomly saw this pic in my files cause I thought it was funny and I forgot her name o.o The chapter that she shows up in will help too.
She's the hostess of the Sohma family's onsen (hot spring) and the monkey (Ritsu)'s mother. She constantly apoligises becuase she feels like she's doing things wrong all the time and freaks out over everything.
