Hello! I am absolutely in love with your Designation: Miracle series. They are the best stories I've ever read for KnB. I kind of have this headcanon for them, though, that while we know the Miracles are super protective of their own human partners, they are also protective of *each others* human partners. So I was wondering if you could do something like that maybe please? If you don't want to, that's fine, you're still amazing and I love you :)
Kasamatsu has never spent a great deal of time with the other Miracles, despite the fact that he’s known them all the longest. He understands now that had been entirely Kise’s intent, and he thinks it’s a good sign when Kise suggests they go shopping with Aomine and Momoi. It means that the other boy has finally accepted that Kasamatsu isn’t going anywhere, that he doesn’t need to be so possessive of Kasamatsu’s time, that he doesn’t have to view everyone as a potential threat who might take Kasamatsu’s attention away from him. Kasamatsu definitely approves of all the implications of the progress Kise has made over the years.
He just wishes Aomine wasn’t so damn weird.
‘Weird’ might be the wrong word, he thinks. Unsettling is probably the more accurate description. Kasamatsu has often thought Aomine is like a wild animal on the court—all instinct and agility and fierce power. Aomine is loud on the court—not vocally, but his presence shouts at everyone who watches. He’s someone you pay attention to, whether you want to or not.
Now they’re not on the court, they’re hanging out in a shopping mall plaza. Momoi and Kise are cooing over some magazine and Aomine is just staring. Watching, silently, the people who are around them, watching anyone who approaches, watching Kasamatsu.
It’s like he’s on the alert. Quiet, and stealthy, like a hunter.
And it’s very unsettling.
He gets up to buy a drink, mostly to catch his breath more than anything else. He likes all the Miracles, but they can be intense, even when they’re just out having fun.
When he turns to head back someone bumps into his shoulder and says, “Watch it.”
“Sorry,” Kasamatsu says immediately.
“Oh, you’re sorry?” the guy says, and his two buddies snicker. “If apologies were enough we wouldn’t need the cops.”
Kasamatsu blinks because it’s just so stereotypical it’s absurd. He’s never had much use for overt displays of machismo, and has no desire whatsoever to engage. “I am very sorry,” he says, mildly. “I’ll be more careful next time.”
“Hey, you think—”
Something slams on the table next to them, causing everyone to jump. It’s Aomine, suddenly there, bristling and so obviously ready to fight. “He said he was sorry. You have a problem?”
And Kasamatsu will say this for the guys, they clearly recognize the bigger threat.
Kasamatsu would laugh at how quickly they exit, if he wasn’t so thoroughly confused.
“Are you protecting me?” Kasamatsu exclaims.
Aomine’s scowl is more petulant than threatening. “Yeah, so?”
So you’re my junior, Kasamatsu thinks, so you don’t even go to my school, so I barely know you, so I don’t need protecting and definitely not from you. All of those things seem a bit too harsh to say. He does say, “Why?”
“Do you even understand what would happen to him?” Aomine says, his whole manner shifting and the anger in his voice gives Kasamatsu goosebumps. He is once again reminded of a predator. “If anything happened to you, that would be it for him, you get that, right?”
Sometimes, it still makes him uncomfortable. How much he means to Kise. It scares him sometimes. Not because he doesn’t reciprocate, but because it’s slightly terrifying being that important to anyone. He is, perhaps, a bit wary against being someone’s all. And. Well. He does know. He saw a bit of what Kise would be like, when they went to Iwatobi.
“I do get it,” he says, his voice gruff. “But you don’t have to treat me like glass.”
Aomine narrows his eyes. “I don’t think you do. You have too much power over him. I wish I could have stopped it before it got this far. If you ever hurt him…”
“Wait,” Kasamatsu frowns, “Are you protecting me or threatening me?”
“I can do both,” Aomine says. “You’ve always been Kise’s biggest weakness and his biggest threat.”
Those are, Kasamatsu thinks, both roles he very much does not want to have in Kise’s life and he scowls at the Miracle for saying it. It also distinctly chafes to hear this from Aomine. He pulls himself up straight and raises his chin (not that it makes much of a difference, since Aomine is taller than him) and he refuses to show any kind of submission to a kid two years his junior. “I would never hurt Kise,” he growls, and if Aomine were anyone else Kasamatsu might be holding him by his collar. “And I don’t need to you to keep me in line or protect me.”
Aomine, to his surprise, just smirks and slings an arm around his shoulder in a friendly manner. “Sure, sure, senpai, whatever you say.”
“Hey!” Kise says when they get closer to the table. “No touching Senpai, Aominecchi! Only I get to touch Senpai, those are the rules—ow!”
“Shut up, brat,” Kasamatsu says. The tap against Kise’s head is barely a flick. He thinks Kise’s “ow” is mostly reactive, part for show, just like Kasamatsu’s tapping is a show. (He could never actually hurt Kise.) When he sits down again, he takes Kise’s hand in his under the table, and his skin grows warmer when Kise looks at him in that intensely-focused Kise way.
Even though he’s not looking in their direction, he feels Aomine and Momoi’s gaze, and thinks probably all the Miracles are watching him and watching out for him, and it’s a strange feeling, but not a bad one.
A/N: That is so kind of you to say, thank you, anon-friend! Headcanon 100% accepted!!! I absolutely feel like the Miracles would also be protective of each other’s significant others. (I picked one in particular, and it got longer than intended, but I do think all the Miracles would feel the same way about the other’s significant others). I decided I wanted to focus on Kasamatsu and Aomine, and then also remembered it would work well with a request by @angelsdontflytheysoar who wanted to see someone warn Kasamatsu about hurting Kise. So thank you, friend, anon-friend, hope you enjoyed!! =D
