A/N: Another prompt for Tumblr where someone wanted Chat to learn about the events of Chat Blanc through X, consequently causing him to get akumatised into Blanc again and thus Marinette has to roll up her sleeves. Here's the aftermath~

"Named emotions are so free
Look, they've changed completely.
With the trigger of my sins seemingly about to melt away
There's no way the meaning of those blood-covered days will go away, is there?"

Signal - Toru Kitajima - Ling Tosite Sigure

"Why...why aren't you running away from me!?"

.

Though he snapped out of Le Papillon's control earlier on, he still gravely struggled with the ferocious power of destruction that threatened to ooze out of his fingertips and cause more calamity in their city and continue to make the death toll rise. The only emotions that ransacked throughout his body and mind were immense fear, raging anger and continuous self-loathing after the things he's seen...

...and the things he's repeated.

All while trying his everything to battle his internal war where the rampaging rogue akuma within ordered him to "destroy", like sharp nails scratching on a blackboard and building up his foreign craving for bloodlust and decay. What little sanity he had left was merely a sluggish dam against the waterful of hysteria that was ready to devour him in the worst way possible.

It was ironic honestly; towards the end, he became what he strived not to be.

And now he was going to end up killing the love of his life all over again.

"...R-Run...please..." Chat Blanc begged, claws digging into the crumbled, concrete floor where he was kneeling with an agonising grimace. The pulse of eradication clenched his entire being like a chain, demanding to be let out and wreak even more havoc, unsatisfied with only pummelling half of the city into nothing.

"More! Destroy more!" It demanded like a viral entity, coursing more anguish through the poor boy's veins and forcing him to collapse on the floor and scream in even more pain. Quite similar to an absolutely, frightened creature being brutally tased to death. "DESTROY THE CITY! DESTROY THE WORLD!" The poor hero was now clutching his head, sinking his lethal claws through his scalp and then blood started to pool from the wounds, staining his pure white locks in a horrific crimson tinge.

.

"If you think I'm going to run away, you have another thing coming!" The sound of Marinette's determined voice broke him out of his violent stupor, the scarily resilient girl marching towards him and gracefully avoiding all the obstacles in her way, ranging from dangerous building residues to razer sharp debris.

The corrupted hero gaped at her momentarily, his ice-blue eyes constricted and his muscles tensed whilst her sky blues shone with conviction, her deep black hair flying around behind her, courtesy on the wild wind that shot through her direction.

Her hair was down just like...that timeline.

Except, everything was also so very different.

And suddenly, he felt a small ray of hope bloom in his chest.

"No matter what happens, no matter how many times that despicable, cowardly man forces you to do his bidding, I'll always be here to save you, Chat Noir!" She vowed without any hesitance, boldly getting down to his level and heaving him up to his knees by the arms with a strength that could rival her masked alter-ego.

Despite her torn, tattered clothes that hung limply off her frame, despite the numerous lacerations and cuts and bruises she received prior whilst trying to help him as Ladybug, despite the fact that she's ended up facing him as an akuma twice,

Never has she looked stronger than she did now.

"So please, come back to me, mon Chaton,"

Her beautiful smile was like the cure to his disease, her presence was like innocence in the blighted city and her touch, oh, when she cradled his hands so wonderfully and brought them against her chest, he felt purified.

"I...I...I don't want to hurt you...not again..."

"You won't,"

"Marinette..."

"Adrien,"

Before he could even blink...

...She kissed him.

And everything went black.

.

The sound of Parisians celebrating and crying with joy and the warmth of another body holding him against them was what roused Chat Noir awake.

His eyes flickered open, revealing soft, emerald greens that reflected the face of the person he loves more than life itself. His lips parted, as if he couldn't tell whether he was dreaming or not, a timid, clawed hand coated in black, reached for her face, grazing his fingers against her jaw with awe.

The awe then turned into a brilliant smile, tears of joy pooling in his eyes and a quiet laugh breaking out of his lips,

"Marinette...you did it...you saved us...you saved us all..."

"Only because you came back to me,"

A/N: Oh wow, I think this is the first mariblanc prompt I wrote with a happy ending. I'm getting too soft man.
