A Mother's Love

(Inspired by The Land of Rest, by DancingInTheStorm)

Something is stealing the children.

All across the world, parents and families are sending in reports of their children going missing, either in their sleep or right in front of them. No one knows where they're being taken or why, but by the time that the entirety of hero society has begun to scramble into life, tens of thousands of children have been taken.

And now, whatever force is stealing away the children has come for U.A. as well, as one by one, the students inside the halls find themselves being taken away with no warning or ability to stop it, going from the general education to management to support, and finally to the hero course.

One by one, the students are stolen away in bright flashes of light...

Until eventually, it is Izuku's turn.

When he awakes, he finds himself in a soft bed, in a room so fanciful that it might've been mistaken for royalty.

When he gets out, he finds a new set of clothes on his side, but when he scrambles out of the room in a panic, he enters into an unfamiliar hallway filled with unfamiliar people.

The children that have gone missing, now together and being herded around by women dressed as angels, all with wings on their backs and halos over their heads.

Izuku runs, ignoring the cries of the missing children and the angels. He tries to fight back against them, but finds that he can't.

He is powerless. One for All is gone.

He runs and runs and runs, until he finds a way out of the building and pushes through...

To find himself in a veritable Garden of Eden. An alien world of endless green plains and forests, crystal buildings, floating islands in the sky, and an endless rolling clear blue sky that shimmered with unfamiliar constellations and nebulas past the cerulean cover above them.

Izuku is shocked, confused, and utterly uncertain of where he is and what to do. He tries to access One for All again, but he can't. It's like his quirk is just... gone. Removed from him.

He's quirkless once again.

And then, he hears a voice calling out to him, and finds a group of children approaching him, and telling him that the angels had removed his quirk, as it was a parasitic element that was polluting his body unlike all the other children who had been born with their powers, to which Izuku is horrified and filled with feelings of worthlessness once again.

The children introduce themselves to him as the group designated as Unbound Heights, composed of the designated group leader Ashla, a mechanic known as Semper, the anxiety-ridden young girl called Keller, and the twin sisters Bella and Donna.

However, these children don't call Izuku by his name. They instead call him Orion, and tell him that he's part of their Unbound Heights unit, which the angels would've told him if he hadn't run out in a panic like he had.

And as they hand him the clothes that he was supposed to put on, he sees the designated tag on them as reading Orion of Unbound Heights.

The group, known as Unbound Heights, is taken away by the Angels to a massive crowd of new arrivals, and Izuku can see that they've all had their quirks suppressed as well. Izuku is split off from his new group and led into the crowd by the angels. There are so many fellow children there that he cannot see his own classmates.

Then, the crowd is shushed, as a single figure, a woman, looms over them.

She calls herself the Mother, and she welcomes the children to heaven.

According to her, humanity is dying. The quirk singularity is taking effect, and the world will soon be destroy itself through the arrogance of their forebearers. More and more conflicts and battles between hero and villains will rise, and the Earth will soon reach its end through the hands of man and the unholy powers that have touched them.

But the Mother tells the children not to panic. She and her angels have saved them from this fate. They have been spared the destruction of their world, and now they have the chance to become something new. They have the chance to become a new humanity, right from scratch, all without the horrors and fears of the mankind that came before.

They have been brought here so that they may start again.

The Mother and her angels have kidnapped thousands, perhaps even millions of children from across the globe because of quirk singularity. They intend to let humanity destroy itself completely, before allowing their new humans born from the children that they stole away to claim what's left of their world once more, with new names and new faces and new purposes.

They intend to rewrite humanity from the ground up, stripping them of their old names and identities and instilling into them something new.

But that is not all that they want.

And so, Izuku Midoriya is let away from the crowd by the angels and dumped back in his his group, the Unbound Heights section, where he begins to learn a few things about his new environment:

One, Izuku and millions of other people are trapped in an alien landscape. Whether it is by a quirk or something else, Izuku doesn't know.

Two, the children have been spread out into a regimented caste system by the Mother and her angels, and with their quirks suppressed, they've been shunted off to different sections of the landscapes and given tasks that suit their skills, regardless of their former quirks.

Three, everyone has been spread out across the lands and divided up so that no one could talk to anyone that they previously knew, isolating them and forcing them to rely on their new assigned groups and the angels for guidance.

Four, everyone else in his group has been in the Mother's and the angels' care for longer than he has, with Ashla, the group leader, being one of the first to arrive.

Five, they've all come from abusive and destitute homes, or not even a home at all, and have no intention of returning to their old lives if they have the chance.

Six, everyone in his group is also formerly quirkless, and they've been put together with a few other groups due to how rare quirkless children have become.

Seven, in a stunning reversal from their old lives, quirkless children are considered by the angels to be part of the highest and most privileged caste amongst the children because their DNA has not been altered from the base human genome to handle a quirk. They are considered to be vital to the Mother's plans, and as such are constantly being monitored by the angels and taking daily doses of blood from them.

Now, Izuku must figure out where his friends and classmates are and how to connect to them, where he himself is and why they truly have been taken, and what's more, what the Mother's plans truly are and how to stop them.

But he has little time to prepare. By this point, all the children of Earth have gone now, and the rest of the Earth has been thrown into a frenzy. Various cases of quirk evolutions are beginning to emerge in the panic, and the world is inching closer and closer to utter annihilation.

Whatever the Mother's goals really are, all of mankind is now at risk.

But Izuku must tread carefully, for the Mother has power beyond that of any human being that has ever been seen...

And with One for All now in her possession and her endgame coming closer and closer because of it, she may very well be unstoppable.
