Chapter Text
Kasumi Yoshizawa & Sumire Yoshizawa
They are both 16 years old gymnasts and...ghosts? It's complicated (see Yoshizawa incident)
~Yoshizawa incident~
As in canon Sumire and Kasumin are twins who are well on their way to become professsionl gymnasts and Japan's future stars (Kasumi more so thatn Sumire) until Sumire, due to her feelings of inadecuacy overall low self esteem and self hatred, attempts to kill herself jumping in front of a car resulting in the death of Kasumi when she tries to save her.
Except not only Kasumi is unable to move on but once she goes searching for the hospital room where Sumire is being held she finds out Sumire is also a ghost and her body is in coma state.
Kasumi then begs and pleads for Sumire to return to her body as the more time she is outside the more the body deteriorates but most of the time Sumire is unresponsive and the few times she isn't she flat out refuses.
Eventually Kasumi grows desesperate watching her parents suffer and frustrated with her sister until one day the doctors come and tell their parents theres nothing else they can do, every day their daughter's condition worsened and it was time to let her go and when they are about to dissconnect her Kasumi jumps into the body and reanimates it.
Everybody thinks it's a miracle and although her parents are extremely confused (Why is suddenly Sumire acting so much like Kasumi?) they cant complain. They have their daughter back. They wouldn't be able to bear losing another one.
Meanwhile Kasumi is... conflicted. She is alive! She is breathing! She didn't want to die, no one does.... BUT THIS IS NOT HER BODY and now Sumire feels like talking?! WHAT DO YOU MEAN THIS ISN'T YOUR BODY BUT MINE?
In reality Sumire was unable to return to her body, she tried to before Kasumi appeared but she JUST.COULDN'T! So the moment she sees Kasumi so easily slip into her body it occurs to her...maybe that's not his body... maybe Kasumi is the one who should live... it was her fault she died afterall (Yep, she knows that's her body but she is very plagued by survivors guilt and evrything she was already carrying)
Kasumi won't tolerate this. The doctors said it was she who died and that's it! (but...she wants to live...she didn't want to die...she cant help the seed of doubt taking place)
Their parents are very concerned hearing Sumire bicker alone in her room. She has to stay a lot of time at the hospital.
Eventually the girls learn to switch places but Sumire cant stay for long inside the body, as if the body was rejecting her so Kasumi occupies it most of the time, slipping inside as easily as Sumire abandons it the moment it happens, only furthering their parents concern.
They hate seeing their parents suffer so the girls start to plan Sumire's return to normalcy, or as normal as it can be when two ghosts have to share a body.
But Sumire doesn't want Kasumi to let her dreams go so she has decided to become the gymnast start her sister was meant to be. Kasumi is absolutely opposed to this idea. The body is in no condition for that.
Cue they meet the Phantom Thieves.
As you can see this fic takes place after all this hospital arc when they finally meet the Pt who will help Kasumi and Sumire resolve their strange situation, starting with the who is alive and who shouldn't.
Sumire is and they have to help her regain control of her body.
Why is it rejecting her? well, Sumire herself is the one who deep inside of her doesn't want to go back. She not only wanted to die but now she feels guilty for getting her sister killed. Her sister who is better than her and deserves to live more than her. Besides she enjoys being a ghost
Unlike Kasumi who wants to live and thus hates being a ghost and enters more easily into the body.
Also them being twins and being in the same place, extremely close when they "died" (in Sumire's case abandoned her body) is why they can share so seamlessly.
There's also the issue of why hasn't Kasumi moved on? At first they believe it's Sumire who due her feelings of guilt is holding her back and not letting her go but the better Sumire gets the more they realize it's Kasumi the one who doesn't want to move on.
She died watching her sister trying to kill herserlf. She is terrified of leaving her alone. Of not being there to take care of of her. Of what will be of Sumire once she's gone.
So like in canon the PT will help Sumire to confront her issues by becoming her friends and supporting her as best as they can and Kasumi with accepting her death and moving on.
Aka Sumire's prologue and Kasumi's epilogue...
Maruki...I'm still unsure of whether to include him in this or not (and how the fuck his dreamworld would fit into this) but if i were to....OF COURSE HE WOULD BE A GENIE
A well-intetioned genie passing as a doctor in certain hospital where....well, someone had to teach Kasumi and Sumire how to swith bodies right? ;)
