Himeji's mom. 41 years old, but looks only slightly bigger than Hazuki and can be mistaken for Himeji's younger sister.
She recognizes Akihisa as "the one on Himeji's cushion and bedsheet." She is apparently perfectly fine with talking about her husband's and daughter's underwear in public and has weird taste (she bought her husband kitty boxers that "got lots of weird looks from his colleagues at his workplace.")
She says that Akihisa should come over to their house someday so she can show him Mizuki's embarrassing photos. She appears at the end of Volume 9, alongside her husband.
