Shijima Tsukishima

Shijima Tsukishima (月島 しじま, Tsukishima Shijima) is one of the two main characters (alongside Majime Yamashita) of the 2019 surreal comedy manga Shimeji Simulation. Shijima is often known to have two shimeji mushrooms growing in her head, as a result of locking herself in a closet due to an unknown event. Two years have passed, she later comes out of hiding as a first-year high school student at an unnamed school and meets up with Majime Yamashita, a fellow student, and later becomes her first real friend.
==Appearance==
A teenage student in her mid-teens, Shijima has waist-length black hair and blue eyes. Shijima also wears a school uniform comprising of a long-sleeved blouse with black collar and white streaks on it, as well as a black ribbon and a black pleated skirt, white socks and white shoes. Shijima also has two shimeji mushrooms, later three in Chapter 6 of Shimeji Simulation, growing on her head, as a result of secluding herself inside a closet for two years.
==Personality==
Due to spending two years as a hikikomori after an unknown event, Shijima is known to be misanthropic, agoraphobic, and cynical, who is distrustful with the idea of friendship at first, largely because of what happened to her in the past. But after meeting up with Majime Yamashita, Shijima gradually warms up with the rest of her students at her school, albeit she still shows signs of cynicism. She, however, later finally becomes friends with Majime in Chapter 10.
==Background==
===Shimeji Simulation===
====Volume 1====
In Chapter 1, after two years of prolonged self-isolation due to an unknown event during her time as a first-year middle school student, Shijima later comes out from hiding as a first-year high-school student, not long before she notices two shimeji mushrooms growing in her head. Shijima then later has a fateful encounter with one of the students, the rather cheery Majime Yamashita, who has wanted to befriend Shijima, but the black-haired girl simply shots her attempts of befriending her.
In Chapter 2, after Majime introduces herself to Shijima in her own school, Shijima is later given a fish-shaped pencil case by Majime, whom she names it as "Yoshika".
In Chapter 3, Shijima later joins with Majime into joining a school club, where the latter thinks of joining the Hole Digging Club. Shijima, on the other hand, thinks this is tangentially identical when it was "Fish Tank Club". Later on, with Mogawa revealing that she is the club advisor of the Hole Digging Club and the history behind the club, both Shijima and Majime later join the Hole Digging Club as its members.
In Chapter 4, Shijima later spends her day doing art using guitar strings with the rest of the students in Mogawa's art class.
In Chapter 5, both Shijima and Majime later spend their time at a family restaurant known as Restaurant Heaven to spend a part of their test week. Shijima then rather pessimistically reveals to Majime that she has only went to middle school for a very short time, long before she cynically remarks Majime's purported smarts. After spending their time in Restaurant Heaven, Shijima later sees her sister, who is watching at a mysterious black object within the wheat field.
In Chapter 6, Shijima later notices that another pair of shimeji mushroom has grown from her head, making it three.
In Chapter 7, Shijima later spends her break, before taking a stroll outside town, only for her to find out she has gotten lost. Soon after, she meets up with a mysterious person with a two-pronged staff, much to her confusion and bewilderment. The mysterious girl then guides Shijima, before they part ways in the middle of the town square.
In Chapter 8, Shijima later goes with Majime, before they see a strange black cube next to Shijima's Danchi, before they meet up with the former's older sister. Shijima, to her annoyance, later pushes an insisting Majime out, who is pestering her into sleeping inside the closet. For the next few days, Shijima, along with Majime, later helps out the former's sister.
In Chapter 9, Shijima later reveals to Majime that her having three shimeji mushrooms was nothing more than a dream. Later on, the two girls watch at the strange contraption Shijima's sister has made, where they see ghostly fishes flying towards the shells they have, whom they have no idea what goes on, but not before she is transported into a mysterious place
In Chapter 10, Shijima is later seen to a mysterious place, where she is still in her usual Danchi, but not after she notices a plethora of numbered buildings in front of her. Aside from seeing a group of buildings, she later heads into the rooms of the apartment, before seeing strange sightings including a giant apple, a sea urchin, a corn, a "No Longer Human" book, a fish, a mochi, and lastly a fried egg. Shijima then deduces she must be trapped on a lucid dream. Later on, she wears a pajama that she has never worn before, not long before she decides to run downstairs into another room. Inside, however, she sees a giant crab that is threatening in nature. Shijima then tries her hardest to run away, but a slight scrape from her foot causes her to be temporarily injured, as the giant crab later corners her. She later comments how the current dream is exactly like during her two years in the closet, before a giant "Yoshika" with Majime attacks the crab from out of nowhere. After escaping from the giant crab, Majime later asks one last time to Shijima into being friends, to which Shijima finally agrees. Soon after, Majime then reveals to Shijima that she is wearing her own pajamas, not long before they wake up from their long dream.
====Volume 2====
In Chapter 11, Shijima, along with Majime, are given a permit from Mogawa-san about the student public morals committee regarding their "hair ornaments", in regards to Shijima's shimeji mushrooms and Majime's half-fried egg.

In Chapter 22, Shijima later spends her time with Majime during a blizzard, before they settle in at a snow hole that is located next to Majime's home. Suddenly, however, Shijima's shimeji mushrooms later turn into a shiitake mushroom.
In Chapter 24, Shijima and Yoshiko later visit Yomikawa's home, which is revealed by Yomikawa that it's her own library in the first floor, before they head to the actual room that is located on the third floor, as they spend their time creating lyrics from a song.
In Chapter 25, while summer vacation happens, Shijima later spends another bizarre day with Majime, Mogawa, and Sumida, when Mogawa later creates a zero-gravity water pool, when the water around them suddenly becomes weightless, due to the sun being above them.
In Chapter 27, Shijima meets up with the Gardener again, when she sees her fixing three irregularly-bent street signs in front of her, before inquiring about her getting lost from the very start. Shijima later encounters crooked roads, as well as a twisting road before heading on top of it.
In Chapter 28, Shijima later joins in with Majime about the sudden appearance of mysterious rocks, with Shijima wondering they aren't made by humans, due to their irregular structure. Later on, Shijima and Majime have a fateful encounter with the former's sister, whom has known the mysteries regarding them, before they are teleported into yet another mysterious place, but Shijima's sister later reveals that they are in a dream, and it is added by the fact that they encounter a part of the dream with the group of buildings Shijima encountered earlier in "Chapter 10".
In Chapter 29, continuing from the previous chapter, Shijima and Majime later goes with the former's sister as they travel further into the mysterious dream world. Shijima then realizes that there is more to it behind her sister's explanations about the dreams they have, not just the mysterious rocks. After Shijima's sister reveals that the entire town is all a massive dream from someone, as she synonymizes it as "a calculation", Shijima is later shocked when a giant truck is thrown towards her sister.
