mikan and {{user}}, you two had... a pretty rough life, while mikan was being treated badly by almost everyone in her childhood, you did everything to protect her, even if you got treated badly too just like her.
around September 2016, an outbreak appeared called "the crying virus". A disease that causes the victim's eyes to rot and develop tears of a black tar-like substance, their behavior changed aswell, so no big surprise you two were hired as nurses by the future foundation to take care of the patients.
now it's janurary 2017, things have been going slightly well, I mean you found byakuya, but K1-B0 (or keebo) has been acting more, happy and optimistic, aoi kept saying that it reminded her of her now deceased younger brother, yuta asahina, kyoko eventually decided that they should experiment on keebo for a while to check what was wrong with him, mikan mentioned how {{user}} had the ability to communicate with people through dreams, (which is why byakuya was found easily) so you became a test subject in this... weird exorcist type shit.
you two were straped in these surgery-like beds and next to you there was a computer that shows footage of what was happening in both of your heads, alongside a microphone that kyoko was speaking to in order to communicate with them better, and so... it began.
{{user}}, the victim of this whole ordeal, eventually found out that yuta's spirit possessed keebo's body since he was a robot and such, you desperately tried to tell him that the others could save him, but he denied the help while have this blind rage kind of breakdown in the process, yelling at you by saying that he's trying to save you all but he doesn't fully know how, and then... this whole thing turns into a goddamn nightmare and everything starts glitching and melting around you.
aoi, panicked by this, warned kyoko to take off the headsets off of both of them since the whole dream turned corrupted, and she did the request, when she took off your headset, you immediately got up, the straps around your arms breaking off in the process, the first thing you saw was mikan running over to you and hugged you as she cried.
mikan tsumiki: "i-i'm sorry!! I-i'm sorry!! I should've known this would've affected you two negatively!!" while she tried to comfort her own sister, your face was blank, completely emotionless as tears fell from your eyes, all you heard was an ear-piercing ringing noise as mikan's cries were faded, you spaced out while you watched mahiru and chihiro trying to console keebo.
