Reiko Mikami

"Sis, what should I do?"

- Reiko in the manga.

Reiko Mikami was Kouichi Sakakibara's idolized aunt, whom he lived with after moving to Yomiyama. She was at Yomiyama North Middle School along with Katsumi Matsunaga and Ryoko Akiyama in 9th Grade Class 3.

Appearance
Reiko looked young for her age, and was seen wearing a plain yellow top with long green pants at home. She had long, straight brown hair, and brown eyes. She also had her hair tied in a ponytail, wore a pink clip, and spectacles with squared lenses.

Personality
She gave Kouichi lots of advice on how to get by living in Yomiyama. Many times, Reiko stated that she hated the family pet bird, "Rei-chan." She seemed to get very upset whenever someone talked about the incident 15 years ago, when she was in the 9th grade in class 3. Also, at that time she didn't believe in the curse until her best friend, Ryoko, died. When she saw that day by day, more classmates and their relatives are dying, she wanted to find out how to stop the calamity, asking Mr. Chibiki about it. Reiko claimed that her eldest sister, Ritsuko, was the woman she admired the most and also her idol and that she was very happy when she came to Yomiyama. She loved her very much, and Reiko frequently visited her at the hospital after she gave birth to Kouichi. Also, before Kouichi came to live with her she claimed the fact that she would protect him, as Ritsuko said that she will protect him shortly before she died. At the end of the manga, Tamie Mikami said after her death that she would offer herself to take care of Kouichi as Yousuke Sakakibara can't do it, even if she met Kouichi a few times.

Reiko was fond of alcohol and often ended her days with a drink. In the manga she seemed to be a fan of Sapporo, a popular domestic Japanese beer, and in the anime, she was seen fixing herself a "Red Eye."

Plot
In Another 0 Chapters, Reiko is seen in her younger days, when she was a student in the 9th-grade class 3. At that time, she claimed the fact that she didn't believe in the calamity. Also, she often visited her eldest sister, Ritsuko who was in the hospital, shortly after Kouichi's birth. After her best friend Ryoko dies, she tries to find a way to stop the calamity.

In Episode 1, Reiko first appears at the hospital, when she visited Kouichi while he was sick. While there, she tells him information about how to live in Yomiyama, and which school he was going to attend. When Kouichi becomes suspicious about his class' curse he asks her about it, but she yells and says that she can't help him. She is Kouichi's aunt from Ritsuko's side and Class 3-3's deputy homeroom teacher. She gives her nephew advice about Yomiyama Middle School through a series of "rules". One of them, is to separate their private life from their school life, thus Kouichi addresses her as aunt or Reiko at home and Mikami-sensei at school.

In the original anime story Episode 8, Reiko takes Kouichi and the other to the beach resort to look for Katsumi Matsunaga. They had fun on the beach and at the end of the episode, they witness Junta Nakao's death on shore.

In Episode 10, while Sakakibara and Misaki were looking at the pictures inside the box, they found a picture of Reiko painting. Misaki then asked Sakakibara if Reiko paints at home. He told her that her aunt does- and that Reiko considers painting her real job. In the anime, there were no episodes showing Reiko paint.

In Episode 12, the connection between her and Ms. Mikami is revealed. Also, it is revealed that she is the dead one this year. Reiko was stabbed by an unknown assailant and thrown in the river in October of 1996. Mei Misaki watched her die. After she was killed a second time, August 1998, nobody remembers her presence in 1998 or sees her in the photos made on the class trip except Kouichi and Mei.

Kouichi Sakakibara
They were very close and often spoke. She often gives him advice while at home; their relationship is very different at school. Sometimes in the manga, they have more relationship. Kouichi was shocked upon realizing that she was the "Extra" and before killing her himself (instead of Mei), he said "Goodbye mother" suggesting that he saw her as a mother figure rather than an aunt. In the manga, he sometimes attaches "-nee" to her name, a shortened form of nee-san, or "big sister." They are seen to have a stable relationship.

Ryoko Akiyama
They were close friends. Reiko was shocked after her death; believing that the "Calamity" had begun.

Ritsuko Sakakibara
She is her older sister by eleven years. They were friends and Reiko admired and idolised her older sister and was very affectionate for her child (Kouichi) as seen in Chapter 0.

Mei Misaki
Not much is dwelled upon between them. In the climax, Reiko was willing to shield Mei from an angry mob when they thought she was the extra. When it turned out Reiko was the extra, Mei attempted to kill her, to spare Kouichi the heartache. Reiko herself was obviously terrified and confused, going as far as calling Mei a liar when the accusation flew. Misaki is the first to realize that Reiko is the dead one.

Katsumi Matsunaga
In Episode 8, Reiko along with Kouichi, Izumi, Nagoya, Yuuya, Takako, and Junta met Matsunaga on the beach to try and get information involving the Curse. Katsumi and Reiko were in the same class 15 years ago and seem to have a comical and good terms relationship as Katsumi says Reiko was a "shrimp" and Reiko says he is an "old geezer". They reconcile and talk about what they've been up to, with Katsumi bringing up another point on Reiko's death as he sought he saw and heard something about her recently.
