Miraculous: Chloe Bourgeois Time Travel Fix-It Book 1 (On Indefinite Hiatus)

Post season 5 in the story, pre season 6 in real life: After Marinette and Chloe are murdered on the first day of the new school year, they end up in Hell and meet all of the kwamis they knew and didn't know about, including among others Gimmi the Kwami of Reality. Gimmi offers them a deal: Chloe being sent back in time to before her first meeting with her mother when she was 3 years old and allow her to download Marinette's future memories before the Origins episodes as well as a copy of Chloe's memories and the memories of everyone in every timeline of the Miraculous Ladybug Quantic Multiverse -- the information of which would possibly be known to the cast only in watching the show stories -- in exchange for the opportunity to redeem themselves and fix the future while also in exchange for avoiding lengthy punishments in Hell. So, Chloe is in the past with her memories intact, and gradually, everyone on the Miraculous Team is given the same amount of foreknowledge. And as the days wind closer to the Battle of the Scarlet Army on Heroes' Day, Ladybug, Cat Noir, and Thora have to recruit a specific amount of superheroes to help them out in their mission. And even after Hawk Moth, Mayura, Lila Rossi, Alexander Donovan, Tomoe Tsurugi, Robert Roth, Xavier-Yves Roth, David Hood, Shadybug, Claw Noir, The Supreme, Cash, and Techno-Pirate in the canonical timelines are apprehended, depowered, reformed, etc., there's still the matter of whether or not Future Bunnyx will try to interfere with the current timeline to create the "perfect" timeline she may or may not have grown up in, a la Sailor Moon's Crystal Tokyo. But all the same, with threats like Future Bunnyx, Hawk Moth, Dreamcatcher, Mayura, Chrysalis, Tomoe Tsurugi, Time Streamer, Bob Roth, XY, Cash, Techno-Pirate, Ignoblia, Shadybug, Claw Noir, The Supreme, and so forth, will the future of Miraculous Ladybug be truly fixed this time around in some far off corner of the Quantic Multiverse? And if not, what then?
