Summary
Izuku was still only a baby when his sister was born, so he had never really known a world without her. The only evidence he had ever been an only child at all was a single album of baby pictures, ended with one of a 14 month old Izuku wearing a onesie that said ‘best big brother.’ To Izuku, the world had never existed without Frisk.
So when she suddenly vanished years later, it took everything in him to not let the world shatter.
+x+
Izuku Midoriya was born without a quirk, later he came to the conclusion that it must be because it would be unfair. That someone had to be quirkless to give Frisk such an amazing power. A power to return to the past to change the future. A power that even supersedes death. His knowledge of that power is what he clings to, because his sister is not dead. She can't be.
Frisk Midoriya was born with quirk that scared her. Sometimes she wished her brother had gotten it instead, he was so much better at adapting. So when her untimely fall puts her in the position to save an entire kingdom, she steps up to be a hero just like Izuku. Even if it kills her- even if kills her over, and over, and over again.

Summary
Two years after the events of the true pacifist ending the player did something incredibly risky. With Chara's assistance, they were successfully able to reestablish a connection with Frisk, but this had unexpected consequences. It caught the eye of a threat far more dangerous than anything Frisk, Chara, or the Player had ever seen before. It captured one of them, and gave the other two a choice, save their friend and convince them to change their mind, or watch as the entire universe is annihilated.

Summary
Frisk has been through a lot. The Underground was quite the journey, with a race of monsters that wanted them dead and an unknown malicious entity that had possessed them, and after a run they'd rather forget the entity is gone. Now, they and Chara are busy trying to help monsters integrate with humanity.
However, there is a reason Humanity doesn't know about magic, and that reason is keen to keep magic away from Humanity, with the belief of the ends justifying the means.
Opposing secret organizations, overseers with plans of their own, finding themselves in a situation where a single kid overturns the status quo that has reigned for decades. A kid that simply breaks all previously known rules.
However, every will can be broken, no matter how strong. So, the Willbreakers lock and load and are sent to handle the threat, with the goal of eliminating the anomaly. And so far, they have done a good job of keeping Frisk firmly in step one.
However, in a distant universe, a human has made a promise to an entity that wishes to compensate for its actions, and through the creation of a Dark Fountain they are now here.
This wasn't how anything was planned, but it will surely be very, very interesting.

Summary
Tiresias has seen the future. The future holds many strange inventions, including a new medium of storytelling called "video games".
Polites, new to the Underworld, finds an ominous cliff with a new friend looking out over the sea of ghosts- a friend with a story to share with him.
In the great tradition of spooky ominous prophets, Tiresias jokes and foreshadows and waltzes around spoilers, while Polites beats Undertale's True Pacifist route thousands of years before computers were invented. Partly based on my own experiences of showing my friends my favorite media and saying cryptic things in an attempt not to spoil it.
