Kouichi, of course, survived, and Mei later went to see him at the hospital, explaining no one remembered Reiko anymore.

Troubled by Mei but drawn to her, Kōichi asks Sanae Mizuno, a nurse at the hospital, about a girl who may have died on the night of his discharge. In Episode 9, Mei is walking along with Kouichi behind Tatsuji Chibiki who asks them about the behaviour of Nakao the day he died. The sisters take a ride on a Ferris wheel, but a bird strikes the glass and causes Misaki to fall out. Nightmare Fetishist: She finds things that any other person would normally find weird and ugly "cute". Turns out she's a living human girl and her classmates just have to ignore her because they don't know who is the real ghost in the class.Stoic Spectacles: In the manga, she wears glasses during work and her behavior at work is more professional and serious than her outgoing personality outside of work. After Misaki's death, Mei was angry, upset and devastated as she lost her best friend and twin sister. He has never been in Yomiyama since he was a child and knows nothing about the rules and dark secrets of his new school, particularly the class 3-3 where he's assigned. He finds Manabu Maejima, who was badly injured and discovers that the dining room is on fire with the manager dead inside. After, it is decided there should be a contest to see who can catch the most ingredients to make lunch, Mei shows Kouichi a starfish and a pufferfish, but he tells her that they aren't edible until she finds an octopus, which latches onto her.

New Transfer Student: He recently transferred to the Yomiyama North Middle School because his father is working in India and sent him to his grandparents' home. Once Mei realized Reiko was the dead one, she attempted to kill her at the inn, only to be stopped by Chibiki, who wanted answers regarding the curse he believed he'd started. Though she ignored Mei with the rest of her class, once it became clear this hadn't worked, Takako was the first student to welcome Mei back into the fold, a fact which irritated Kouichi, who felt the class was pretending nothing had happened. In the manga, she briefly appears talking with Mei; and in the novel, she always stays in the company of Izumi's group. Not because she might be the Extra; just because her best friend wouldn't help her instigate a witch hunt against their classmates.Replacement Goldfish: Yukiyo made a doll which resembles Mei to create a duplicate of the child Yukiyo lost during her pregnancy.

Kouichi says something similar to this to Izumi in Episode 10, when she tried to place the blame on Mei. The sheer despair of losing her sister has apparently rendered Mei null to any other trauma, as she doesn't even flinch at Shoji Kubodera killing himself in front of the entire class. Since he'd already met Mei once before, he thought nothing of approaching her and starting a conversation, inadvertently violating the conditions of the charm and bringing doom to everyone.Later on, Izumi learns how to break the curse from Tomohiko, which leads her to stab Takako in the throat, believing she was the extra. As such, she starts to become very protective of her whilst going to an amusement park the next day. Another S is a side novel set in the same time period, an adventure of Mei Misaki during summer vacation. Misaki told Mei that she found out they were twin sisters before Amane (their grandmother) let it slip, because they looked alike. She tells Kouichi about how she can see things that should remain unseen, stating that she can distinguish the color of death by uncovering her left eye and determine whether something is alive or dead.

Doom Magnet: Because she's the dead person, her presence in the class 3-3 brings about the Calamity which kills the class members and their direct family. Tranquil Fury: In the anime, he acts completely stoic when killing the other students to determine who the extra is.This eventually makes him a "sacrifice" as well, but he doesn't mind since he can still hang out with Mei. No one could identify who it was, and the deaths began, year after year, with no one remembering the "extra" after graduation; they would disappear.
