If you're sensitive to any of this then skip this chapter. Other than that, enjoy!

"Now this is genocide... The monster inside... The voices in your head..." User muttered as she glared at the... the THING that was her and Mentality from AsylumTale. They had come to her au... killed her friends... and SHE was the only one left... to strike them down... She just prayed that someone would come help her... "They're telling you to wash away the crimson stains! To leave us all for dead!" She remembered when she had heard this song, finding it fitting to sing when fighting the manipulative experiment.

Starling's eyes lit up at the others words, laughing their soft giggle that sounded so similar to User's as the other carried on. "I know a way that you can cut at every last tie..." User growled as the experiment giggled, launching forward before resting their knife on User's neck. "The friends you've made... how could you watch all of them die?" They hiss, trying to get into User's head. User growls, shoving the other off of her harshly. "And every world that you destroy will burn as you planned... and in the end they're gonna fall and fall at tour hand!" She yelled, Starling grinning as they stood.

"I see your mind, now it's slipping faster!" User yelled, Mentality's voice slightly slipping into her own. "Kill or be killed, the only thing that matters~!" Starling laughed, their grey eyes glowing as they span their machete. "Across the land, all of their ashes scatter~" they hummed softly, her eyes brightening their glow. They were attempting to use their manipulation powers on User which failed because User was LITERALLY a part of them. "WHO'S THE MONSTER NOW!?" User yelled, eyes glowing. She was panicking, pretty badly at that.

Starling hummed softly, launching at User again before flicking their fingers as a ball of fire flings towards the others chest. "Now this is genocide, the monster inside! The voices in my head!" They giggled insanely, eyes glowing dangerously as User only just dodged the attack they fired. "They're telling you to wash away the crimson stains. To leave us all for dead!" User hisses, bones surrounding Starling.

"No-one told you there's no going back for once you attack, there's no way to prevent every single drop of blood you spill will stain, it's real. For death is permanent..." User growled coldly, bones firing at the other harshly. "You're just a monster..." she growled, a massive cloud of dust firmed as she grinned. "And now you're just a monster..." she hissed, turning her back to form her rest.

The creators eyes widened in surprise at an axe being placed at her throat. Starling... had survived that..? It would've killed anyone else... "And you can see it in my smile and in my eyes. There's no compassion, no, there's nothing left inside!" Starling chuckles into the others ear, slowly bringing their axe down in User's throat. "Over and over, no, I'm never satisfied..." User's eyes flicked open as she heard this line,quickly teleporting out the way. "MADE YOUR DECISION, NOW YOU'RE GONNA HAVE A BAD TIME!" She yelled, Starling peeking up at the other finally seeming to get their fighting spirit.

"I SEE YOUR MIND, NOW IT'S SLIPPING FASTER! KILL OR BE KILLED, THE INLY THING THAT MATTERS! ACROSS THE LAND, ALL OF OYR ASHES SCATTER! WHO'S THE MONSTER NOW!?!" The creator yells, flicking her fingers. She seemed to summon at least a thousand gaster blasters, firing it at Starling. The experiment narrowly dodged, laughing to themself as they wiped sweat from their head.

"Now THIS is genocide... the monster inside... the voices in MY head!" They laughed as they launched at User before their weapons, User having a knife and Starling having an axe, clashed against each other's. "They're telling you to wash away the crimson stains, to leave us all for dead..." User hissed in the others ear before forcing Starling away with her axe, grinning sadistically.

"No-one told you there's no going back. For once you attack there's no way to prevent every single drop of blood you spill will stain, it's real! For death is permanent..." User growled, spinning her axe as she held herself back. She knew Mentality wanted her to kill... She couldn't... She WOULDN'T!... right...? "Heh... you're just a monster..." Starling growled as they stood, harshly twirling their axe as they approached User. "And now you're just a monsteeeerrrr~" they sang, raising their axe above their head. Mentality screams inside User's head for her to focus, User only having a second to look up before the axe was lodged into her forehead. "And now y-you're just a-a monster..." User murmurs before collapsing, dead before she hit the ground.

Starling grinned, pulling her axe out of the others skull before swinging it over her shoulder. She walked forwards, holding the others soul with a sly grin. "Such a shame, huh User? To think that we're one in the same... yet I'M still stronger..." she growled before her gaze casts to the doorway of judgement hall with an eyeroll. "What do you want..." she muttered, clenching her hand around the soul, threatening to destroy it and kill the creator forever as the figure slowly stepped out from the shadows...
