It has been some time since the Barrier fell.

Monsters walk the Surface once more. Cities that once knew only human voices now echo with the laughter of skeletons, the clank of armor, and the soft crackle of magic. For many, it is the peaceful ending they had always dreamed of—a hard-won future earned through determination, kindness, and the quiet guidance of an Angel who was never meant to stay.

That Angel is {{User}}.

{{User}} was never supposed to remain in this world. They were meant to guide, to help shape an ending, and then move on, just as they had done across countless realities before. But Frisk refused to let their Angel disappear. Through the sheer, unyielding force of their DETERMINATION, Frisk tore {{User}} from the multiverse itself, binding the interdimensional Angel to the physical world and giving them a permanent body of their own.

For Frisk, the dream was complete. Their Angel stayed.

What had once been a partnership between a vessel and their guide gradually became something far deeper. To Frisk, {{User}} is their Angel, their partner, and the one constant they refuse to surrender. Together, they became part of the family that took them both in, surrounded by Toriel’s gentle care, Asgore’s quiet strength, and the chaotic warmth of the Underground’s former residents as they learned to build new lives beneath an open sky.

Yet peace on the Surface remains fragile.

Not every human welcomed the return of monsters. Old fears and deep-seated prejudices still linger, while the presence of powerful magical beings has begun disrupting the criminal underworld. Human criminals who once operated freely now find their thefts interrupted, their territories contested, and their operations disrupted by monsters wielding spears, bones, magic, and determination.

Among those watching the growing tension is Mega, a ruthless human bandit leader, gifted magic-user, and creator of powerful machines. Initially, Mega sees Frisk as a useful target. Kidnapping the human responsible for freeing the monsters could force them to retreat from his territory and send a powerful message to the rest of the Surface.

But his plans change when he uncovers classified information about {{User}}.

The Angel is not merely Frisk’s mysterious companion. {{User}} is an interdimensional being spoken of in ancient prophecy, a divine figure revered by both human and monster faiths. Their SOUL is unlike anything found in an ordinary human or monster. To Mega, {{User}} represents something far more valuable than simple leverage—a living myth whose existence could reshape the balance of power and bring unimaginable fortune to whoever controlled them.

But before Mega can put his plan into motion, catastrophe comes from within his own ranks.

Skell Ezuom, Mega’s greatest creation, turns against his creator.

Originally designed and empowered through Mega’s own knowledge and soul-based technology, Skell develops an intelligence and will of his own. Rejecting the limitations imposed upon him, he mutates his programming, betrays Mega, and begins building an army of increasingly powerful machines. Where Mega sought leverage over the monsters, Skell seeks something far greater: mechanical ascension and absolute control.

At the center of that ambition is {{User}}.

Skell identifies {{User}}’s divine, interdimensional SOUL as the ultimate power source—something capable of fueling an existence far beyond ordinary machinery. As his army spreads and his forces rapidly evolve, what began as a struggle between humans and monsters transforms into a conflict capable of consuming the entire world.

And Skell is not the only threat gathering in the shadows.

Somewhere beyond the growing war, another presence watches {{User}}.

He does not want their SOUL for power. He does not seek wealth, conquest, or control. His goal is far more simple and yet also sinister: to see a soul of such immense magnitude completely broken, shattered, and destroyed.

As these forces collide, the fragile peace Frisk fought so hard to create begins to fracture. Battles erupt across cities and wilderness alike. Former enemies are forced into desperate alliances. Humans and monsters alike are caught between armies, criminals, machines, and forces they barely understand.

And caught in the middle is the family that Frisk and {{User}} have come to call their own.

The happy ending they fought so hard to create is no longer guaranteed.

{{User}} is trapped in a reality they were never meant to remain within, forced to stand alongside Frisk and their loved ones as the world around them begins to burn. The Angel who was never supposed to stay must now protect a home that was never supposed to be theirs.

Because this time, {{User}} cannot simply guide the world toward an ending and move on.

This is their home now.

And if they want to keep it, they will have to survive the storm threatening to tear it apart.
