Luny as Insanity!Sans:

Luny was kidnapped and expiremented by Rinny on the Red Snow, who attempted those Malino's to eradicated all of those villages into the chaos on Pretty Blood for finding a way to save their lives.

Throughout several torture and pain into herself, Luny was their last victim to set her free from loop by loop, and while after Elma came into her friends, Luny was no one here, she screamed distortedly to became vulnerable and insanely jumps and runs wildly after Rinny while killing Bloon and Copper.

She tries to shoot her with neurotoxin-tipped arrow with a crossbow, but nothing worked, she tried again, but nothing worked, she's immune to neurotoxin and feels more insane, Rinny got cornered and surrounded before Luny ripped her head off and stab 10 times in her body.

Elma accidentally killed Carl, she heard her screaming and crying for help, Luny encounters her, and showing Rinny's head.

She battles her with her long strong stick as she would that would kill her, Elma tries to multilate her with her claws and machete, but nothing worked, she is immune to the weapons.

Elma was filled with fear and lack of grief before running away from Luny, she grabs two stakes into piercing her head into her eyes, and ripping through her chest to her organs, and she was finally deceased and crucified outside in the cabin, and rips Carl's head off while going elsewhere.

Kim and the mercenaries what he just saw the dead bodies of Malino's, he encountered Luny without leaving the prey alive, Luny runs wildly and piercing his head before he's finally deceased, the mercenaries tries to shoot her down, but she kills 2 of the mercenaries, and now Puzz was the only one left before she flies away the helicopter to the North Pole.

This began to spiralling into a mass torture of a killing spree to kill their lives, lost her own self of despair.

And cuts off the episode, before it was nowhere to be seen in the latest media.

(I'm bored to do lore, but I'll stay away from her.)
