Summary
Nagi is curious about Isagi: why is his skin so much softer and smoother than the rest? Why is his waist so slim and yet his hips are anything but slim? Isn't he a beta? Aren't they supposed to be stocker and squared like Zantetsu or that braided-hair guy?
Why is Isagi so different from everyone else?
...
"Oh."
in other words, Nagi discovers the existence of the fairer sex and Isagi is painstakingly dragged to explain how omegas work, and--No, Nagi omegas don't work like that, who taught you these things? AV videos?

Saving my first kiss for the one I love by Incarnadines
Fandoms: Blue Lock (Manga), Blue Lock (Anime)
19 Sep 2025
Tags
Summary
“Stop! If you’re thinking of kissing me, forget it right now.”
Kaiser didn’t pull back, just furrowed his brow and glared. “Huh? So now you’re playing it chaste?”
“Tch…I know you’ll mock me for being childish or a virgin or whatever…but I’m saving my first kiss for the one I love. That’s the one thing I’ll never compromise on!”
A first kiss should involve blushing cheeks, intertwined fingers, and a sweet, candy-like aftertaste, right? Definitely not something to share with a rival bound only by physical desire...
Just a story about kiis going from fwb to lovers!

Summary
Isagi Yoichi is the youngest, most brilliant forensic profiler the bureau has ever seen cold, precise, and terrifyingly good at crawling inside the minds of monsters.
But no one knows that the real monster has always lived inside him.
When the untouchable serial killer known only as "The Emperor" begins leaving taunting clues addressed directly to Isagi, the game becomes personal.
Michael Kaiser is beautiful, ruthless, and impossible to catch. He kills with elegance, leaves roses on his victims, and signs every scene with a crown.“You don’t kill for pleasure,” Isagi tells him the night they finally meet face-to-face.
“And you don’t hunt for justice,” Kaiser replies, lips curling into a smile sharp enough to cut.What starts as a deadly dance of predator and prey twists into something far more dangerous: obsession. Need. Two psychopaths circling each other, daring the other to blink first until the line between hunter and hunted disappears entirely.
They both know how this ends.
One of them will break.
One of them will beg.

Summary
Kaiser and Isagi, Bastard München’s Ace Strikers.
When their rivalry on the field starts drawing interesting media attention, Blue Lock's Higher ups hatch a wild plan: Isagi Yoichi and Michael Kaiser, archnemeses and Bastard München’s top scorers, must pretend to have something between them.
Forced into awkward interviews, staged dates, and too many shared, purposeful moments that make BLTV fans crazy, the line between fake and real begins to blur.
But… this is all business, right? Fanservice? It’s not a big deal.
Besides, it’s not like real feelings will come into play.

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.”

Summary
Isagi might have made the worst mistake of his life during the holidays, but he doesn't have time to dwell on it. There's a tournament to win, a team to fix, and Rin Itoshi standing in his way.
Somewhere between forced training, reluctant teamwork, and a confession he never saw coming, Isagi makes a choice. Maybe it's the right one. Maybe it's not. But in the end, someone was watching him all along.

Summary
Isagi Yoichi came to Blue Lock to find the passion he once had for football. He wanted to feel the way he had when he was younger—ecstatic hearing the sound of the ball whooshing into the back of the net. Everything about football was normal for him now, predictable, structured and organized into his daily routine, and entirely too dull in the suburbs of his hometown. He knew that he could never be the best in the world; it was impossible for someone like him, wasn’t it? Someone who lost their love for football.
To relearn the ability to arrogantly declare that he would be the best in the world—to feel his heart pound erratically as he watched the best of the best in front of him and strive to reach their level, he accepted Ego-san’s proposal. He wanted so badly to feel that way again, but his heart faltered in front of the goal, in front of his… teammates, who he regretfully wished he could confide in like a normal player. He felt like a fraud, taking this spot from someone with more passion than him.
Ego-san promised that this program would give him a reason to play, give him his passion back, and make him realize his own selfish ego, but… what if he’s wrong?

Summary
He thought he was finally starting to get the picture. He was finally starting to see underneath that damn mask, behind those irritating words and actions, the real him. But he was wrong.
So incredibly, painfully fucking wrong.
Isagi isn't only skilled at reading the field—he's always had a knack for reading people too. At least, that's what he thought until he met the most insufferable soccer genius to have ever existed: Michael Kaiser. Kaiser, who's been harassing Isagi and getting in his way since day one; Kaiser, who beyond all doubt could've been nothing more than a simple, arrogant, self-centered asshole; Kaiser, who despite all of that, he can't stop thinking about for some goddamn reason—he can't stop his feelings of hatred, entangling with both awe and curiosity, and he can't stop the chain of events that he set off spiraling out of control, all leading up to a reality darker than anything he ever encountered before: the bitter truth behind the naked emperor.
Canon divergence playing after Ubers. They gotta drag each other through their issues first before they can work them out one by one.

Summary
Yoichi presented as a Prime Omega at 10.
While there has been a lot of progress in the past centuries, Omegas still were viewed as delicate and fragile. Especially in Japan where the percentage of Omegas has decreased. In fact, currently, there is a 88% Beta population, a 10% Alpha population, and a 2% Omega population. Prime Alphas make up 0.05% and Prime Omegas make up 0.001%.
In a world which decides your worth based on a biological category from birth, Isagi can be considered to have won the genetic lottery.
But for him, it's a curse.
