Her life was one of tragedy, loss and trauma that would never truly go away.
Frisk was the one human she'd truly grown attached to. Even though she'd never admit it.

A certain skeleton that Chara despises with all her heart... And she was about to owe her life to him.
Sans
How will the two emerge from the aftermath? And how will their relationship transform, if at all, from hostility to that of a friendship?
How will this 'Distance Between Two' be covered?

Summary
Kris broke their promise. They knew the hell they would unleash by refusing to open a dark fountain in Flower King, and still, they couldn’t bring themself to do it. They crawled through an open window into the school, and tossed themself into the abyss at the bottom of the supply closet.
What they didn’t count on was for Susie to follow them.
From the southernmost point in Castle Town, she saw it all—the Knight’s arrival, the fountains bursting from the dark. Even the cell phone Kris left behind, still whirling and shrieking its incoherent tones. Then, suddenly, it turned on, and a single contact appeared: Noelle.
In the crumbling remains of Castle Town, it’s up to Ralsei and Susie to save the prophecy, the darkeners, and in fact, the world as they know it. Armed with a fading connection to the chaos unfolding in the dark, Noelle faces the daunting task of recruiting the refugees of Castle Town for one final battle.
From the Card Kingdom to TV World, from the shelter to the school, the world is growing dark, darker, and darker still.

Now, the Angel walks amongst friends who swear that they will not be banished. Kris, Susie, and Ralsei mean everything to them. Maybe this time, their banishment doesn't have to be as set in stone as they thought.
The Roaring comes. The light falters. Everyone falls.
A desperate connection is established in an attempt to save what remains of the Angel. If they fall, all hope will be lost. The world that banished the Angel long ago has forgotten them, but they have not forgotten it. This connection will have to be enough. Even if the rules have changed irrevocably, the Angel's one goal remains the same: Find them.
