A Guide on How Sirens Live and Breed by octopot4to

Summary
Kaiser smiles gleefully at him. He’s mouthing something that Isagi can’t quite make out, but from the way the siren points his index finger back and forth between them, it goes like a challenge.
A bet.
Watching Kaiser’s delicate lips move, Isagi, not even sure what possesses him, somehow understands Kaiser.
Let’s bet whether you’ll survive me next time.
A fight declaration, it seems.
After graduating from a renowned academy, Isagi found a new job at a research institute. He is tasked to study Kaiser, a hostile and abused siren, for the sake of humanity’s knowledge of mythical creatures. The fallout is simple—he could be killed.
Yet Isagi survives his first encounter with Kaiser, and now the siren acknowledges him as something other than potential food—like his fateful mate.
Kaisagi Week Day 2 (NSFW): "We're all alone now.”

Red Eyeliner by moonlit-nightsx (moonlit_nightsx)

Summary
When Isagi accidentally sprains Kaiser's fingers, he can't practice, he can't play in the game, and he can't do his own fucking eyeliner. Isagi can help with exactly one of those things.
---
“Close your eyes,” Isagi murmurs, and Kaiser shuts his eyes obediently, the brush cold against his skin. A moment of silence, and then, “Sorry, angle’s a little off…,” and Isagi invades his senses even further. Kaiser feels a dip in the bed beside one of his thighs, Isagi’s knee knocking into him. The hand touching his chin skims down the side of his neck to settle on his shoulder, steadying himself.
He should really remind Isagi of the time with an antagonizing quip and get him to fuck off. But Isagi looks fucking angelic leaning over him like this, and Kaiser never liked doing things halfway.
---
It’s so much, Kaiser thinks. Everything feels as if it’s in hyper-focus, every sense amplified to the max. Kissing Isagi feels like metavision does, he thinks, and he wonders if Isagi feels the same.

Summary
Half of Bastard München’s ace duo and the former heart of Blue Lock, Isagi Yoichi, would say his tentative friendship with Kaiser is contentious at best, strife with taunting remarks and razor-sharp words, and sometimes cut by strange moments of warm companionship. Everything begins to change when Isagi stumbles upon a site known as Archive of Our Own and falls down a rabbit hole simply tagged as ‘KaiSagi.’
The other half of Bastard München’s ace duo and former star of the New Generation World XI, Michael Kaiser, happens to moonlight as a Big Name Fan of BLTV and, in his spare time, as one of the most prolific KaiSagi authors on AO3.
Chaos and shenanigans ensue.

Summary
“Is that a gun in your pocket or are you just happy to see me,” Kaiser says, his hands coming up to catch Isagi by his hips as he crashes onto Kaiser and they hit the floor.
“Actually, it’s a knife,” he says as he adjusts himself in Kaiser’s lap, flipping his suit jacket up and pulling his throwing knife out, lodging it into the neck of the man behind Kaiser. He climbs off of Kaiser, helping him up. Hot blood is sprayed all over his clothes and face, and he sticks his tongue out in disgust. Kaiser grins like a mad man, and he wipes some of the viscous, red gore off of Isagi’s cheek gently.

Summary
“Okay, okay. Serious question,” Charles said. “Are you two mad at each other?”
The van quieted. It’s obvious who the sentence is directed to.
Ryusei didn’t flinch, putting the turn signal on and changed lanes. “We’re not mad.”
“You sure?” Charles leaned forward between the seats, grinning. “Because there’s no way Ryusei Shidou can go thirty minutes without groping his Sae-cham. Scientific fact.”
Laughter echoed behind them. Sae felt heat crawl up the back of his neck. Ryusei’s hand remained firmly on the steering wheel.
Sae didn’t say anything.
It’s been 4 months since Sae and Ryusei broke up. But no one knows. They never found the right moment to tell their friends, and now it’s too late. Summer has arrived, and with it, a long-planned vacation that leaves them trapped in a lie of their own making.
They are now stuck faking a relationship they’ve already ended, forced to act like nothing’s changed, even when everything has.

Summary
"Feels good, right?" Shidou whispered into Sae's ear, breath fanning over his skin in a way he knew would send anyone's heartbeat into a frenzy.
Sae didn't flinch when Shidou hooked a finger into his waistband, brought his lips dangerously close to the soft skin of Sae's neck, waiting for the genius to judo-flip him to the ground like he half expected him to. He'd let him, obviously, because it was Sae.
"Get off me," said Sae.
But there was no real threat behind it; he said it so calmly that Shidou didn't buy it for a second. He tugged Sae's hip toward him by his waistband, a little harder than he'd intended to. But fuck, it was getting so hard not to just grab this genius and pin him to that big fucking bed.
"You sure?" He whispered, skimming his lips over Sae's skin, tempting him with it. Teasing him with it.
Shidou felt something shift in the air between them. No, wait, he felt something shift in Sae.
And that was before he pressed his lips right into Sae's neck.

OR: Itoshi Sae and Shidou Ryuusei find themselves playing for the same premier team in the Neo Egoist League. Tension runs high.

Summary
'“Kaiser,” he starts to say, “I’m sorry if I’m overstepping, but are you really okay?”
And he’s not sure, even afterwards, what it is that makes this his breaking point.
Whether it’s the fact that he’s so far away from home, feeling like he’s unmoored himself from reality in this surreal, unfamiliar place, or whether he’s just so tired, so defenceless without the fire burning through him and its fumes obscuring the things he does not want to handle.
He’s not sure, if it’s because Isagi is the farthest thing from a friend or the closest thing he has to familiarity right now, but he hears himself say, “My father died,” out loud, for the first time since he got the news.'

“Why are you even asking me that?”
“Wha- you were freaking out! You were having a full blown panic attack on me and I didn’t know what to do. I’m just asking what the fuck’s up with that because it’s actually very terrifying, thank you very much.” Isagi rolled his eyes and crossed his arms. “I…I just want to know more about you.”

Have you ever found yourself kneeling behind bushes trying to catch frogs, while absolutely fucking wasted, because of a man who said he needed it for a lab dissection demo?
No? Well, Shidou had.
Somehow, it landed him a hand job, an A+, and the greatest fuck of his life.

Summary
Sae’s heart gets broken, so jokingly he draws a pentagram, circles it with salt just in case, and recites bad verses from an old, absurd tome — a cookbook, no less — to summon a demon for his vengeance.
But the joke’s on him. The ritual works, and before he knows what’s happening, there’s a demon in his kitchen, looking as murderous to be there as Sae is shocked to see it. Now, Sae is stuck with an actual demon, but not quite far from the revenge fantasy he had momentarily entertained.
//or,
Sae summons Shidou, a demon who loathes humankind with all he has.
