History Characters / ShimejiSimulationShijimaTsukishima

* AndIMustScream: Being trapped and isolated while with her simply dreaming endlessly about Majime is an {{Understatement}}. She's essentially still ''alive'' after a millennium has passed and as TheHermit it did no favours for her. She's repeating it every single day within those thousand years, which is a much worse fate than death, and it's clear that she feels a strong pang of loneliness ''every'' time she wakes up from her dream.

** In the one-shot Mina (another inspiration for Shijima) is friends with Yocchan whom she was romantically in love with and had a [[BleachedUnderpants sex scene at one point]], before her untimely death led her to become a social recluse. The sex scene and her relationship to Yocchan was completely omitted, leaving only the recluse part transplanted onto the current Shijima's backstory.

** Invoked in Chapter 43, where after a rather [[BleachedUnderpants risqué]] scene with Majime, she forcibly kicks Majime away from her, fearing that she would slowly disappear. [[BeCarefulWhatYouWishFor She gets her own wish...]] At the expense of now being sent to a deserted, chaotic part of the world they were in where Majime is nowhere to be seen and with their house gone from sight.

** She appears [[BleachedUnderpants in a slightly risque oneshot]] as Mina, where part of her depression is caused by a female friend, Yocchan, who she has sex with committing suicide. The backstory and Mina's character design was carried over to the current Shijima albeit with some BroadStrokes, such as the omission of the risque moment as well as her backstory with Yocchan.

* IWillFindYou: Her final goal is to reunite with Majime once again as shown in Chapter 48 where she rides a train before departing to Majime's world at the final panel.

* MergerOfSouls: Almost in one scene where she was having a suspiciously romantic interaction with Majime, before it suddenly goes [[MoodWhiplash completely nightmarish]] when she goes into a FreakOut moment over being closely merged by her. She doesn't take it well and resorts to threatening her to stop it.

She's essentially still ''alive'' after a millennium has passed and as TheHermit it did no favours for her.

* TomatoSurprise: Shijima's past is completely unknown where the only thing that was even mentioned about it was her time as a recluse, at first... Until the big reveal shows that Shijima knows her true origins as a creation of the simulation all along, a fact withheld ''by herself'' for the past 45 chapters. Since the entire world is simply a simulated reality and not real, it makes sense.

* WalkingSpoiler: She's the protagonist of the story, but talking about her gives away immediate spoilers. Even mentioning the very quote she speaks in ''[[FirstEpisodeTwist the first chapter]]'' during her looking at the mirror gives away a heavy {{Foreshadowing}} about her true nature as an ArtificialHuman. Her TomatoSurprise moment also spoils the main reveal that Shijima and Big Sis are not {{Self Made Orphan}}s.

* WhoWantsToLiveForever: By the time 1400 years have passed, Shijima's fate is infinitely worse than death when she becomes immortal, unable to die at all but to think of Majime, sleeping every single day with each passing dream, while her loneliness continues to sharpen further. And she does it ''every single day''.

Trapped and isolated while simply dreaming endlessly about Majime is an understatement. She's repeating it every single day within those thousand years, which is a much worse fate than death.

* DivergentCharacterEvolution: Before the manga existed, Shijima is basically a transplant of her two previous incarnations who both each have different personalities of their own. The current Shijima is much more divergent than the previous, who has developed an entirely different character that is a mix of her previous versions with various changes to it, as well as a much more developed backstory, personality and appearance.

* CallBack: One of Shijima's shimeji mushrooms grow larger during Chapter 22 when it was snowing after Majime wished for it. It grows yet again in Chapter 45 when it was ''also'' snowing, only this time it was done due to the collapse of the simulation's order.

** Similarly, they're also alive by their prolonged existence. Unlike Chito who is dead and has been a living soul for a thousand years without ageing, Shijima is chronologically a thousand years old and is still alive without any change to her appearance.

Due to Shijima's nature of being a WalkingSpoiler character, every single tropes about her will be [[Administrivia/SpoilersOff unmarked spoilers]]. Administrivia/YouHaveBeenWarned.

Over the course of the story, Shijima gets involved in Majime's antics, as well as others including her sister and the members of Hole-Digging Club including Mogawa and Sumida. However, she is later involved into a much bigger mystery surrounding the true nature of her world. As well as the revelation of her true nature as [[ArtificialHuman a creation of the simulation]] along with her sister and countless others within it.

* SelfMadeOrphan: {{Subverted}}, as she and her sister had no parents at all. They're both ArtificialHumans who were both created by the simulation along with others.

** While Mina in the one-shot manga becomes a recluse due to the death of her friend Yocchan, Shijima in this manga becomes a recluse where she hid herself after an incident regarding an unknown friend of hers. It is heavily {{Broad Strok|es}}ed because her slightly risqué moment with Yocchan was completely omitted, leaving only the part where she becomes a recluse, which was eventually carried over to Shijima's own backstory.
