The Klein Invariant

Please don’t ask me anything about real analysis—I don’t remember. All posts are my own work.

Qifrey is an astronomer, a witch weaving stories about the stars. And his best friend is Olly, bringing those ideas to life as an engineer.

Every week, they visit a restaurant to “review the lemonade.” Olruggio feels like there was another taste just on the tip of his tongue. But try as he might, he can’t get Qifrey to share it yet.

Sequel to Selkie Boy.

There was something undeniably comforting about Olruggio. Even when Qifrey was in pain, paralyzed, and tired, the Watchful Eye could keep his atelier running.

The guilt of erasing his memory next time would be overwhelming.

It’s time to steal an important memory, a real one. Olruggio is going to create it with him, so they can steal a present from the future.

It’s not much. It’s fucked up, and ugly, and frustrating. But it’s real and theirs and just for this moment.

Olly and Qifrey love it.

Takes place between Selkie Boy and Caribbean Blue, as the borrowed lines imply.

Sequel to A Wander’s Work. Qifrey will have to deal with what happens after Coco comes home. Or perhaps, he’ll just have to deal with the fact his Watchful Eye knows what happened there, in that sealed room. But can’t he just have a moment of peace first?

Heyyyyyyy so remember that scene in Ep. 9 where Qifrey gets the shit kicked out of him? Pepperidge Farm remembers.

Anyway, Olruggio hears the sound of rushing water and runs downstairs, only to realize his best friend has done something dangerous and paid the price. Thankfully, he’s alive. And very clingy.

It’s some time after Qifrey is freed from the Silverwood Curse. Or maybe it isn’t, who counts the days they survive after death?

Regardless, Olruggio is forcing him to eat. The way Olruggio always has—convincing him that if Qifrey eats, he’ll eat with him.

If anyone was going to survive a second Great Dying, it was going to be Ishigami Senku. He was stubborn, smart, and most of all, just unlucky enough to be prepared for even the most unlikely of scenarios. But to find himself in a future where he was the only omega alive was a lot to deal with. And then to realize he has to fight an entire empire of only alphas while still having to go through heat every six weeks... it was...exactly what he'd prepared for. But what he didn't plan was one of those alphas /immediately/ defecting without any interest in mating him. That was worth more investigation.

Idol Asagiri Gen has once again forgotten to make his own coffee. Without any choice of where to go or when to be there, it's a miracle he can visit the Coffee Lab twice in a blue moon. Still, the proprietor is the only person who really listens to him. And he may be the last person needed to give him that last little push toward his dreams.

Little does Senku know, a trip to the bar after work will spin into a night of trivia and a drag show. He just wanted to go home and read ArXiv before bed, but now... now he's 11,000 yen poorer with a new friend, or perhaps something more.

Being reborn into a world without alpha and omega dynamics does not resolve the gender issues of the past--if anything, it only intensifies them as fewer members are available to select from. If Senku has the issue that he cannot select anyone, even as he tries to sublimate his newfound alpha ruts, Gen finds he has to opposite--the many alphas of the Empire of Might are drawn to his omega scent like aphids to sap. The solution to both of their problems, however, seems to always lie just out of reach given that the world is over.

I had a funny idea about if the village saw the Northern Lights and all sat around and made sushi. It'll be fun, I thought. And then I had to do a bunch of research to make it work. So here's the end product. Senku and Gen are adorable together. No one falls off the Pegasus. Yuzuriha and Taiju talk. And almost all the science makes sense because I'm an astrophysicist, and I could do no less.

Taiju may not have been in the advanced courses with his best friend. Or felt like his best friend considered him his best friend most of the time. But Taiju knew that he was probably the person closest to Senku before the certification, especially after his father went to space. So it was a little hard to miss when someone else, someone completely different from both of them, was having a positive effect on his best friend. He has to express that in... well, a Taiju way.

After 3000 years, it's a miracle that Ishigami Senkuu can remember which star has precessed to True North. No one has fallen through the cracks, no one is dying. But in just this moment, Gen feels it best to remind Senku just where and who he is.

Takes place right after If You Play God, We're Gonna Crumble One By One.
