Chitose MIHARA

The kind and generous landlady of Kobato's apartment and Sayaka's old classmate. She is married and has twin daughters, Chise and Chiho. Fujimoto also lives in Chitose's apartment complex.
She's a version of Chitose Hibiya from Chobits, but has different last name (after her husband), and her daughters are just like Freya and Elda from Chobits, but they have human ears and probably are not machines.
