A long time ago, Gabriel Agreste gave his body and soul to revive Emilie and cure Nathalie, thus costing his own life. With him gone, every alliance ring were removed and all miraculouses were restored to their original forms, being kept with their rightful holders as well. The Butterfly brooch is currently in the possession of Cerise, aka Lila Rossi and while she plots her next move, there was another danger coming to Paris.
It cuts to the lovely pair of Marinette and Adrien walking through Paris, both were extremely happy at being officially together now and with no one in their way. Adrien was happy his mother was back but that his father now is gone, though he was relieved he won't obey him anymore or being slaved around.
"Isn't it a beautiful day Adrien?" Marinette asked Adrien.
"Huh? Yes of course" Adrien snaps out of his thoughts.
"I thought to, it's been a month since the threats are over" Marinette said.
"Yes, no Monarch around and no akumas" Adrien said. They soon noticed a poster of an upcoming event at the Louvren.
"What's this?" Marinette took a closer look at the poster.
"Come see James Murphy's latest discovery at Louvren" Adrien read the poster.
"James Murphy? The James Murphy?" Marinette wondered.
"Yes, It is said he found the remains of Atlantis" Adrien said.
"Really? Well lets find out" Marinette said and they all headed to Louvren.

Once they arrived, they saw a tall caucasian man with black hair and goatee standing near an artifact that supposedly came from Atlantis. It had the symbols of a shark, an octopus, a dolphin, a crab and even a seal. Adrien and Marinette were about to take a closer look when they bumped into someone.
"Mom?" Adrien saw it was his mother.
"Adrien? What are you doing here?" Emilie asked her son.
"Well Marinette and I wanted to see the exhibition" Adrien explained.
"That's right, Emilie" Marinette replied. Just then the man telling about the artifact came near them.
"Well if it isn't Emilie Agreste" He said.
"That's right, And you must be James Murphy" Emilie said.
"Yes, but call me Jim" James said and sees Adrien and Marinette.
"This is my son Adrien" Emilie said.
"Pleasure to meet you Mr. Murphy" Adrien shook hands with him.
"Adrien huh? I've heard about you being a model" James said.
"Well was. This is my girlfriend Marinette" Adrien introduced Marinette to him.
"Marinette Dupain-Cheng" Marinette shook hands with him.
"Nice name. As you can see I found this relic from one of my expeditions at sea. From 2000 below the surface I finally found the location of the sunken city of Atlantis and some evidence, scientists say this is 100% real" James said.
"Incredible. And I thought it was a myth" Marinette said.
"Hmm, Many thought so until an disaster struck and sunk it" James replied. Adrien's eyes widen, Plagg once told him he sunk Atlantis due to too much cheese.
"Ah, Is that so? Well that's horrible what happened" Adrien scratched his neck.
"Unfortunately, But there are urban myths something might be able to rise it up" Jamed replied. Adrien nods and Marinette looks at the relic, something hitting her in mind.

Much later, Adrien checks through info about Atlantis on the computer with Plagg munching on cheese nearby.
"Tell me Plagg, are you hundred percent sure you sank it due to too much cheese?" Adrien asked him.
"Yeah but I couldn't control it" Plagg replied. Then Adrien checks the spell book and after a couple of pages he finds one of the Miraculouses of the sea.
"The sea miraculouses were all lost when the city of Atlantis sunk 9000 years ago. None has been able to find them for millennials." He read the page.
"Oh dear" Plagg read as well, feeling guilty at what he has done.

Somewhere else, a dark figure stood inside some hotel room, looking at his watch.
"The time has almost come to take down this so-called Cat Noir." Said a small raspy voice similar to Imperfect Cell.
"Patience Chompp, We'll right at the right moment he's vulnerable without Ladybug" Said the mysterious figure.
"Precisely. I've waited a long time for this moment, Plagg will suffer for destroying my home!" Chompp reveals himself as a shark-like kwami.
To be continued.
