Mikami-Sensei

"You can't kill your own classmate!"

- Ms. Mikami  

Ms. Mikami is the assistant homeroom teacher of 9th Grade Class 3 at Yomiyama North Middle School. She is also the art teacher at the school and presides over the art club. She later takes over as homeroom teacher of 9th Grade Class 3.

Personality
Ms. Mikami is shown to have a different personality when she's at school. She is described as a beautiful teacher and was dubbed the 'killer type'. Many students wanted her to be their homeroom teacher instead of Mr. Kubodera. Yuuya seemed to have a crush on her.



Appearance
In the anime, she has long brown hair that is slightly wavy and brown eyes. Mikami is usually shown wearing a black blouse with a white sweater, a white medium skirt and white shoes. In the manga, she has black hair, black eyes and wears spectacles. Also, her hair is shorter and it is tied up in a ponytail. Mikami wears the school standard uniform.

Plot
When Mr. Kubodera committed suicide in front of the classroom, Chibiki told  Ms. Mikami to call the police and an ambulance. She then runs out of the classroom, shocked and scared. She was also present at Nakao's funeral along with Chibiki in Episode 9.

In Episode 11, after hearing Takako's broadcast, she went out the hall and saw the students trying to kill Mei since they were thinking that she is the dead person. Ms. Mikami went forward to stop them, but Yukito refused to listen and charged towards Mei with a broom. She rushed to Mei, taking the hit for her and fainted, and lost some blood from her head, but not enough to kill her.

In Episode 12 it's revealed that Ms. Mikami is actually Reiko. Mei revealed to Kouichi that Mikami is the extra in Class 3, the source of the Calamity. In a flashback, Reiko originally drowned a year and half ago, when she was stabbed and pushed by an unknown student and Mei witnessed what happened. After Kouichi kills her, nobody in the school remembers her or see's her in the photo made in the class trip except Kouichi, Mei and Chibiki.

Trivia

 * Although not immediately obvious, Ms. Mikami and Reiko are the same person. Kouichi behaves differently around her whether she is at school or at home.


 * Although in the manga (and live film), she has her hair down and doesn't wear glasses as Reiko, and ties her hair up and puts the glasses on while teaching as Ms. Mikami, in the animated version these were switched. So anime-Reiko has glasses and tied-up hair while anime Ms. Mikami has no glasses and her hair down.


 * Like her character Ms. Mikami, the voice actress Miyamaki Misayo is also "The Other". Cleverly, to throw off viewers, they created a fake voice actor name for Ms. Mikami and even a fake webpage. Miyamaki Misayo does not exist and if you rearrange the "ki" and "yo" in her name, it's "Yomiyama Misaki." The real voice actress is of course the same as Reiko, Naoko Sakakibara, which is revealed in the credits of Episode 12.


 * In the original novel, the revelation of Ms. Mikami and Reiko's connection occurs at the climax of the story. Ms. Mikami was not killed by a student, although her body was found in the river, thought to be an accidental drowning. Mei did not witness her demise either.
