Miraculous Ladybug AU Idea
Manon: the Little Ladybird
Right. I had another idea.
It’s a reveal fic. Kinda.
The gist of it is that Darling Marinette gets found out.
But it’s not her parents. It’s not Alya, it’s not Adrien.
It’s Manon. Adorable, bratty, Manon.
It can be before the Puppeteer episode or after (in my head it isn’t).
Bloody Manon.
How I see it Manon is waiting in Mari’s room to apologize for what she did while akumatized. Mme. Chammack is arranging a catering event with the Dupain-Chengs at the station as a small apology of her own to her coworkers, and they’re so busy that they don’t notice that Manon sneaks upstairs to see Mari, even though they told her not to go up because Mari had to do some studying for an important test.
But Mari isn’t there. The room is empty with Jagged Stone playing softly and the repaired dolls are sitting on the desk, with a few papers with sketches of the other akumatized forms of people. There is a quick one of her on the bottom of the stack. On a sticky note next to the dolls is the reminder to make a new pair of Chat Noir and Ladybug for Manon, but she doesn’t see that.
Manon picks up the Chat Noir and Ladybug dolls and plays with them nervously for a little while; after all just a few days ago she had used these to cause a lot of problems. Manon is sitting by the chaise, so she can’t be seen from the skylight.
Which leads to Ladybug soaring through her skylight, bouncing off her bed and popping up in the middle of her floor. Manon is stupefied, and before she can call out to her idol and rescuer, there’s a flash of red light and Marinette is standing where Ladybug once was and smiling at a red creature that was giggling happily.
Manon stands and stares.
Tiki see her, squeaks, and attempts to hide.
Marinette freezes and then slowly turns around to peek at who finally found out her secret.
After a suitable amount of Freak Out™ Manon promises to keep her secret and is the proudest seven to eight-year-old in the world when she’s told she’s the only person Mari’s ever told.
She starts to ask to spend more time at the Dupain-Chengs with Marinette, who kinda adopts her as her little sister/protégé.
She learns all about fashion at the hip of Marinette and all about duty from Ladybug.
(Manon is the only one who sees how exhausted Marinette is after her patrols as Ladybug, is the only one who knows how many injuries she’s bandaged over and the scars that mean Mari will never again wear a midriff bearing top, seen Marinette soak her twitching hands in water after hours of pinning, and sewing, and hand embroidering the clothes that will make her future.)
Manon blooms with her newfound sense of responsibility and after a few months her mother gifts her with a phone with four numbers programmed in: her mother’s, the station, the bakery, and Marinette’s personal number.
She adds Ladybug’s compact number the moment she alone with an Ladybug emoji in the name slot. It’s set as her number three speed dial.
All of a sudden Ladybug knows where all the shit is going down because Manon has her on speed dial and an alert on the Ladyblog.
Not only that but she has the schools number and she can call and get Marinette out of class by stating that she needed Marinette to come and get her, she didn’t know where she was and her mom was at work.
(She only does this if it’s really bad though.)
In an interview with Alya, she asks what the secret to her new response time to danger.
Ladybug winks, puts a finger to her lips, and declares “I have a little Ladybird helping me. She’s slowly earning her spots.”
After this Manon demands that her number be given to Chat Noir, and Marinette agrees. So the next time they get together before a patrol and before he can ask any questions she opens her compact to make a call, the only identifier a small red ladybug with no spots, before a voice chirps out a greeting and asks for his number.
After coming to terms with their off-screen sidekick, he gives her the number to his personal phone with the understanding that she was only allowed to text, and not call, that phone.
(Manon low-key ships LadyNoir, but that’s mostly from Him always saving her big sister than any real idea on their relationship.)
Adrien is a sad kitty one day and shoots a text to her on accident.
He immediately gets a response and they become bros.
Manon is now determined to play matchmaker because this guy is the perfect guy for Marinette, and much better than that Model that never pays attention to her.
Insert Classic LadyNoir love square happenings complete with Marinette getting over Adrien (painfully) and Adrien noticing that “Wait. Dis a Boss-@ss-B*tch.”
Then BLAM: Manon is being chased around Paris because if Akuma (no she was not found out, just reasons okay?) and in the midst of saving her Ladybug becomes injured and Manon is the one who directs Chat Noir (Ladybug in his arms, Ladybird-known-as-Manon on his back, no problem.)
On the roof of the Dupain-Cheng bakery.
Where Marinette lives.
Ladybug turns into Marinette right after they drop onto her bed.
While Chat gapes in stunned awe, Manon is on the move pulling the first aid kit out and after having Tikki ensure her that she could be woken “It was just the pain that knocked her out.” Mari is summarily shaken awake and handed the muscle relaxant cream that she immediately spreads on her shoulders and sides with Manon deals with the big one at the small of her back.
Chat is a sad-ashamed kitty, but Marinette is okay with it, as long as he doesn’t reveal his own identity. Her family and friends had just been put in danger, she refused to put his in danger too.
Marichat occurs intensely and mild pre-Adrienette colors school hours and group projects with adorable littlesister!Manon as a constant no matter what side of the mask.
That is all my brain has.
It is dry now.
Whyyyyyyy?!
Someone has to come and help.
Please.
