Reiko Mikami

"Sis,what should I do?"

- Reiko in the manga.

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

Personality
She gives Kouichi lots of advice on how to get by living in Yomiyama. Reiko states that she hates the family pet bird "Rei-chan." She seems to become very upset when someone talks 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 firiend, Ryoko, died. When she saw that day by day more and more classmates and their relatives are dying, she wanted to find out how to stop the calamity, asking Chibiki-sensei 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 in Yomiyama. She loved her very much and Reiko frequently visited her at hospital after she give birth to Kouichi. Also, before Kouichi comes to live with her she claimed the fact that she will protect him, as Ritsuko said that she will protect her shortly before she died.

Appearance
She looks young for her age and mainly wears a yellow top with green long pants at home. In the anime she has long straight brown hair, and brown eyes just like Kouichi. She also wears her hair tied in a ponytail, a pink clip and spectacles with squared lens. In the manga, she has long black hair and black eyes.

Plot
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, or 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 Reiko at home and Ms. Mikami at school. In the original anime story Episode 8, Reiko takes Kouichi and the other to the beach resort to look for 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 apparently Reiko paints for a living. In the anime, their were no episodes showing Reiko paint. In episode 12 the connection between her and Mikami-sensei it is revealed. Also, it is revealed that she is the dead one this year. Reiko originally drowned a year and half ago, when she was pushed by an unknown student. Mei watched her death. After she was killed, nobody remembers her or sees her in the photo made in class trip except Kouichi, Mei and Chibiki.
