Undertale: Fallen Angel

Unwinnable

Looking into the soulless intensity within the demon child's gaze makes Frisk realize they never truly escaped. As is the nature of a restless spirit, Chara continued to exist in different planes- including but not limited to their victim's consciousness, nightmares, and most worriedly, their SOUL.

Evil never truly dies. But without a compliant host, it can do nothing but sleep... and wait. 

The hellish red fades from Chara's eyes, leaving nothing within them but pitch-black darkness, not unlike the surrounding void. Frisk wouldn't be surprised if the void IS Chara and the form greeting them is a mirage trying and failing to imitate something alive.

"You don't seem confused," Chara observes with a hint of curiosity. "Only afraid."

"We've met before," the teen says, turning away. "But you already knew that."

Nothing recently has gone Frisk's way, but at the very least, they can deny their former partner the satisfaction of being feared, however artificial the brave facade may be. It doesn't appear to work, since when they look back at Chara, a wide crooked grin meets both ends of the demon's flushed cheeks.

"Then why so unnerved? None of this should be new. You're... different than the others."

"Whatever," Frisk says, still avoiding eye contact. "All I care about is getting back home."

This isn't the first time they've seen Chara visibly baffled, as that had been on their second Genocide run. But Frisk is still surprised to see the demon's signature smugness disappear.

"Home?" They echo. "Not the term I'd use. Especially given your unfailing ability to destroy it."

"That's not me anymore," Frisk argues. "Hasn't been for seven years."

Chara's bafflement has now evolved to full-blown bewilderment.

"Impossible," they hiss. "Our deal..?"

"Broken," finishes Frisk. "At least in my timeline."

Their legs move on their own, in the direction of the demonic child before them. In three steps, Frisk hovers over the source of their neverending dread. But they don't see it. They fail to see the unfathomable monster that tormented their dreams; the one that lingered with every hopeful thought of a better tomorrow. 

All they can see now is a bully that's been outgrown.

"No matter how much I begged, no matter how many times I apologized, it was never enough," their hands ball to fists. "With every reset, you'd watch me do everything I could to make things right just to kill everyone and everything I ever cared about. Every. Single. Time. I'd even do it myself so we could speak only to be ignored. So if I couldn't get what I want... then neither could you."

A sudden realization flashes across Chara's face.

"You waited me out?"

"I STARVED you out," Frisk clarifies. "At the start, right on your grave, I'd rest, I'd grow hungry, and I'd die, over and over; however many times it took for us to reach a new compromise."

Even if they don't want to admit it, Chara is clearly impressed, which shocks Frisk due to it being an emotion other than sadistic glee. 

"For our new deal, I got my SOUL back, along with a chance to do it all again," they continue. "Then, once it's all over, we'll destroy everything and finally move on."

"But that's not your intention, is it?"

"No," Frisk confirms. "Once I die, there will be no more resets. Everyone will have the chance to continue living their lives, and I won't come back. And even if I do, you will never hurt anyone ever again."
