A/N Another crossover between Miraculous Ladybug and Vocaloid. The song that inspired this is the Synchronicity trilogy

Chapter 1

An unknown, unseen realm covered in darkness, where the only light comes from the crystals set around the cavern. The guardian Kwami stands alone, listening to the sorrowful prayer being sung within, doomed to guard the lair of a dragon. To calm the soul of the powerful and merciless dragon all divas, young women who have been taken from their homes, never stopped singing until the bitter end. Many Divas have lost their lives, their last thoughts of nothing. While listening to the prayer the present Diva sings, the song dies off and a dull thud is heard past the large doors, followed by a roar, and thus history repeats itself.

Elsewhere

"ADRIEN! Where are you?" running through the halls is a young french-asian girl in a simple white under dress and pale maroon vest and skirt with apron. The front of the vest and apron covered in flour from helping her parents within the mansion's kitchen. Her family has joined the work staff when the wife of the aristocrat visited their bakery once long ago, and fell in love with the pastries the family made there. Later asking in they would come work in the mansion's kitchens. Since then Marinette and the youngest son of the family, Adrien, have been best friends.

Once she spots the boy in question she slows down when she spots the boy's father beside him. The two once shared the same bright blonde hair until the older man's turned grey. The boy who has been her friend since the two have met inherited his mother bright green eyes, his clothes are black tights, white collared shirt, and forest green vest. Marinette keeps her distance from the two to avoid the older man, knowing he doesn't approve of her heritage, or friendship. She hides behind a nearby corner to avoid detection.

Once Adrien's father leaves his son alone, Adrien turns and spots one of Marinette's blackish-blue pigtails behind the corner, and makes his way over. Upon hearing the slight steps approaching Marinette looks to see her friend making his way over. Getting up, and dusting herself off to the best of her ability she stays where she is to avoid being seen by Adrien's father should he return. "Hey Marinette, I heard you were looking for me. I'm sorry I couldn't come sooner my dad had to give me my daily lecture."

knowing all about the lectures Adrien gets she responds "I hope it wasn't about me again, I only wanted to give you this." Reaching into her pocket of her apron Marinette pulls out a little pendant carved into the form of a cat. The fur area burned to give it a more black like appearance with a hole in the arch of the back for the simple string allowing it to be worn around someone's neck. Placing it around Adriens neck she watches his reaction to see if he likes it. "I remember how you liked the black cat that used to come by for food. I tried to get it as close as I could, but I didn't want it to bring you bad luck."

Adrien takes to newly adorned pendant in hand to get a closer look at it. Once he places it back down to rest against his chest he pulls out another wooden pendant from his vest pocket. The pendant like the first one is carved out of wood in the shape of an insect, this one a ladybug. The black spots are also burned to give it more character. The hole was placed at the top. "I didn't know what to do for yours, until a ladybug landed on the piece of wood I was carving from. I remember that my mother once told me how a ladybug stands for luck, but I can't remember what for." Placing the pendant in Marinette's hand the two than go off to play, unknowing of those who watched from the building.

Inside

The guards escorting and messenger from the king were talking to about a maiden to replace the recent Diva, who Gabriel knew all too well. As the walk down a corridor they look out to spot two children. Their attention going to the girl, who even with the shabby clothes shown just as brightly as any of the past diva's "Excuse me, but who is that girl out there playing beside your son?" The messenger asks Gabriel Agreste.

The Master of the Mansion looks out the same window to see his son playing with the kitchen help once again. Looking to the Messenger and his two escorts an idea suddenly arrives. "That girl is the daughter of some of the kitchen staff we have here. My late wife hired them, but the daughter reminds me too much of her." 'As well as why she is gone.' He thinks to himself. The escorts and messenger than converse amongst themselves until finally turning back to Gabriel "The girl is much older than we would like, but we think that she would work for the next Diva." Mr. Agreste pretends to think about it until finally he says "I will allow you to take the girl if you allow my sons to be suitors for the king's daughter when they come of age."

The three visitors go back to conversing once again shocked by the mere prospect of the agreement Mr. Agreste has proposed to them. After thinking about it they agree, and say they will be back tonight for the girl. Gabriel goes back to looking out the window, once the distraction and reminder is gone, perhaps his son can finally be useful to him again.

That Night

The Dupain-Chengs just finished their responsibilities in the kitchen, and head toward the exit to see their daughter waiting for them at the door. Each taking a hand, they begin the track back to their home above the bakery they used to run. Once the building is in view they spot the messenger and escorts that their employer was talking to before. Getting in front of his wife and daughter Tom Dupain looks to the three men, focusing on the one he believes is in charge. "If you are looking for some pastries, I'm afraid you'll have to look else where. We no longer run the bakery here."

The leader shakes his head and looks down at Marinette peaking out behind her father's leg. "I'm afraid that is not what we are here for. The last Diva has passed on and we found the next one in your daughter. So if you could get out of our way, we'll let you get on with your day." Sabine hugs her daughter close as Tom moves to protect them. "I didn't know you started taking 5 year olds now with out their parents consent."

"Yes well, desperate times call for desperate measures. Now hand the girl over or we'll be forced to make you, even at the cost of your lives." Before Tom can say anything else his daughter moves between them and spreads her arms out. Trying to seem as big as she can. "If I go with you, you have to promise to leave them be" She said. The messenger nods his head, and holds out his hand. Marinette walks up to take it. offering her parents one last look. With that she gets in the carriage and the parents are left alone in a house that will seem too empty without their little girl's laughter.

The next morning when they arrive at the mansion the son of their employer spots them without his friend. "Where's Marinette, is she sick?" Before either of them can mentally prepare themselves, tears come to their eyes unwanted. They later go to Mr. Agreste to say they will not be coming by anymore, that they will be going back to the bakery after that day. He doesn't question them when he already knows the cause, and sends them on their way.

All throughout the days that follow, the only comfort that Adrien had was the wooden pendant made by his friend. When he attended a meeting with his father he would mess with the pendant hidden in his pocket to avoid it being confiscated. That was his only comfort through the years, when he and his twin went to the palace to meet the king's daughter. The wooden cat in his vest pocket or under his shirt was the only thing that made being around the spoiled girl bearable.

Back in the Cavern

The guardian of the dragon can't help but think that fate can be cruel, it separated the friends who were actually meant to be together. the new Diva was at a much younger age than the past chosen, but still older than those before, so they had memories that tied them to the outside world, just not many. As time passed on those began to fade, all but the memories held within the little pendant of the bug around her neck. The Newest Diva has learned many prayers to sing, and the dance to go with them, all while unaware that her friend was in the same building. Once she came here, the door of a new adventure opened.
