Middle school misaki gets sent to the future cause ya know strain and sceptre 4 find him and think it's best to keep him under their roof because he keeps getting panicky over the whereabouts of saru. Ahh and angst on saru's end, saru snapping at small misaki and bringing up how they're not even friends anymore, then small misaki runs away bumps into current misaki and cue confused awkward 3way angst
Ooh I can see Fushimi snapping at him too, like the strain of trying to pretend that nothing’s wrong while he’s got middle school Yata right there with his bright eyes and his firm belief that Fushimi is awesome and Fushimi with the knowledge that none of that is going to last and finally he can’t take it anymore and yells out something he’s going to regret. Like say there’s a Strain issue and Fushimi gets called into Munakata’s office, he’s dumbfounded to see small confused Misaki sitting there leaning against the wall. As soon as Misaki sees Fushimi he gets this wide smile like ‘Saruhiko!’ and then he pauses, wondering if Fushimi got taller and why’s his hair like that. Munakata explains that this seems to be the result of a Strain power and that Awashima contacted Homra to confirm that the ‘real’ Yata Misaki is still there and unharmed. Middle school Misaki is all confused by what that means, Fushimi ignores him and asks what exactly Munakata called him here for. Munakata just gets this mysterious smile as he says he thought it would be best to keep Misaki here for the time being with Fushimi as his caretaker, as it seems that so far Misaki’s been getting anxious as to where Fushimi’s whereabouts were and they want to make sure he stays safe because who knows how the Strain’s powers work, like if Misaki gets killed here will that affect future Yata and change the timeline and who knows what.
Fushimi reluctantly takes Misaki in, complaining the whole time and trying to ignore the pained feeling in his chest every time Misaki calls him 'Saruhiko’ and asks him about why his future self isn’t here with Fushimi. Fushimi just tells Misaki to shut up and not cause trouble, saying that he’s busy and doesn’t have time to play with him. Misaki’s a little hurt and confused but he’s like fine, whatever you say Saruhiko and then he promptly gets all excited over Fushimi’s sword or Fushimi’s powers or just a variety of things. He keeps calling Fushimi 'cool’ and Fushimi keeps gritting his teeth and scratching at his burn scar. Then say Fushimi has to leave Misaki for a bit and go out on a mission, during which he runs into Yata (using 'Yata’ for normal Yata here and 'Misaki’ for the middle school version). The two of them fight like always and maybe Mikoto intervenes to tell Yata to cut it out and come on, Yata stops fighting and follows Mikoto like a dog wagging its tail while Fushimi grits his teeth and can’t do anything. When he gets back to the dorm he’s all pissed off and it doesn’t help that there’s Misaki all bright-eyed asking him questions again, wondering when he’s gonna meet his grown up self and wondering if he’s as cool as Saruhiko is and finally Fushimi just snaps, stating that Misaki’s older self isn’t here because they aren’t friends anymore. Misaki stares at him, all shocked and heartbroken by the revelation and probably not even completely believing it and Fushimi gets this twisted smile on his face as he starts mocking Misaki a little the same way he would grown Yata, like are you that stupid to think we would still stay together after everything. Maybe he tells Misaki that this is all his fault too, like this broke because of you and Misaki can’t take it and just runs off, calling Fushimi an asshole.
Misaki runs out of Scepter 4 and he’s wandering the streets all lost, not sure what to do or where to go. He wonders if maybe that wasn’t even Saruhiko at all and then thinks again that he needs to find him, to see where the real Saruhiko went because of course they should be together. That’s when he literally runs into his older self, Yata’s all shocked to see what appears to be his little middle schooler self standing there in front of him crying. Yata tries to calm him down and that’s when he hears Fushimi yelling his name. Fushimi comes storming up, not having even noticed Yata because he’s focused on little Misaki, muttering that Misaki’s an idiot and he can’t just wander off or the Captain will have Fushimi’s head. Yata’s like 'Saruhiko…?’ and Misaki looks up and suddenly it’s very awkward between them. Misaki grabs Yata’s arm and asks if it’s true, that he and Saruhiko aren’t even friends anymore, and Yata just stutters and tries to find an answer because he doesn’t really know what to say, having his younger self here and so obviously distraught and Yata himself hates saying it, doesn’t want to be the one to confirm that the friendship he thought would last forever has broken.
