Ritsuko Sakakibara is Kouichi's deceased mother, Reiko's eldest sister, and Yousuke's wife. She only appears in the school graduation album and the old Sakakibara family pictures. She went to Yomiyama North Middle School in 1972 and was in the same class with the dead Misaki Yomiyama, 9th Grade Class 3.


Kouichi's father mentions that she is a very special lady, and has a great taste in men. She is also a supporting sister. Reiko mentions that when her father went against Reiko's decision to attend art university, Ritsuko is the only one who stood up for her and supported her. Also, in the manga, in Another 0 chapters, Ritsuko is shown as a kind-hearted, calm, kind and peaceful woman, as she says that she will protect her younger sister after Reiko yelled at her. Reiko claimed the fact that she admired Ritsuko the most and she was her idol. Also, she was very happy when Ritsuko came in Yomiyama to give birth to Kouichi. Ritsuko was shown to be a loving and caring person.

She has brown hair, as well as brown eyes in the anime, and has brown hair and black eyes in the manga. In her middle school days, she wears a ponytail in the anime, where in the manga, her hair is shoulder length and her hair is worn down. Also, she is seen after Kouichi's birth in the manga wearing her hair tied in a pigtail.

In the manga, she appears also in Reiko's flashback. After Kouichi came to live with Reiko, she is seen standing in front of Ritsuko's altar, talking to her. It is unknown whether she died while giving birth to Kouichi, or if she died shortly after his birth. In chapter 10, it is hinted that her death was in that class, because of the calamity. And it was also confirmed that she is actually The Death Of May of the 9th Grade Class 3 in 1983. In Another 0 chapters, it is shown that she died shortly after Kouichi's birth. Also, Misaki Yomiyama enters the room, Ritsuko calls his name and then dies. The cause of her death is unrevealed. After her death, her father (Kouichi's grandfather), is always seen sitting in front of her altar, probably still depressed about her death, claiming that he is sick of funerals (including Reiko's). Also, Rei-chan (family's pet) always repeat the phrase "Poor Ritsuko, poor Reiko". In Episode 5, when Kouichi was looking at his mother's class picture, the librarian, Tatsuji Chibiki came to him and asked about his mother. Tatsuji is shown to know about his mother since he was the homeroom teacher of class 3-3 in 1972. In Episode 10 Kouichi had shown Mei some old pictures with Ritsuko in her teens.
