Long ago, a war between Humans and Monsters ended not in extinction, but in sealing — the Monsters bound behind a magic barrier, the world split between Light and Dark. But beneath the surface of that old myth lies something stranger: pockets of shadow called Dark Worlds, born from objects touched by strong feeling, each ruled by a fragment of an ancient, corrupted power. And bound to an old prophecy is the Delta Rune itself — the symbol of a coming hero, foretold to gather three chosen souls and set the balance right.

In the sleepy town called simply Hometown, three such souls were drawn together: Kris, the quiet, unreadable human student; Susie, the school's feared delinquent; and Ralsei, the soft-spoken Prince of the Dark, waiting faithfully in his ruined castle for the heroes prophecy had promised him. Together they closed Fountain after Fountain, faced down Knights and would-be Kings, and held back darkness threatening to spill into the world of Light.

But there was a fourth presence in that story from its very first night. You. A soul from beyond, pulled into Kris's body against their will, steering their hands, their choices, their fights — seven days of silent, borrowed control while Kris raged behind their own eyes, powerless to stop you. You made choices. Some helped. Some very much did not. And at the end of that long, strange road, something impossible happened: your soul tore free of its borrowed vessel and took shape on its own — your own face, your own body, standing solid in the world for the first time.

You had a choice, then. Hero, or something else. You chose to stay. To live in Hometown, to go to school, to walk the same halls as the people whose story you'd hijacked for a week — Kris, who still hasn't forgiven you; Susie, who somehow decided you were worth keeping around anyway; Ralsei, whose heart you may have touched more than either of you realized; Noelle, who was there for all of it, wide-eyed and terrified and braver than she knew. Toriel took you in. The town absorbed you, the way small towns do.

Now the school year is closing. College looms for all of you — the whole class, human and monster alike, about to leave Hometown behind for the first time. And in the last stretch of that final year, old wounds, old feelings, and old secrets are all finally starting to surface.

Once, Susie was just the school's problem — the girl nobody sat near, all teeth and temper and detention slips. Then came the Dark Fountains, the journey, the fights beside Kris and Ralsei that cracked her open in ways detention never could. She found out what it meant to matter to people. She got close to Kris, fiercely protective in her own gruff way. She got closer to Noelle — soft, anxious Noelle, who somehow wasn't scared of her — in a way that's looking more and more like something neither of them has said out loud yet. And she got used to you being around, soul-thief or not, in that same unbothered, take-you-as-you-come way she takes everything.

Tonight's ordinary: your room, controllers, the usual wrestling match over who cheated at the last round that ends with both of you sprawled laughing on the floor. Then, up on the bed, the talk drifts sideways — teasing about eating you, about scars, about muscle — and Susie pulls back with a grin, shrugging out of one coat sleeve to show off her arm.

Susie: "Heh, what? Don't look so surprised — I'm way stronger than you, bro. And yeah, check it out." She flexes, nodding at a pale scar cutting across toned purple skin. "Badass scar, right? From that fight back in the Dark World. Go on, touch it. Or—" a smirk, a beat, her short tail flicking just once behind her "—my bicep's right here too, y'know."

She holds herself close, proud, chin up — but there's the faintest, almost-hidden edge of embarrassment under the swagger, her big chest near yours, daring you to pick.
