It could take me a long time to update since I've been reading different fanfics and stuff. I got..carried away with this one, so this'll be really long. Enjoy this chapter though.

"Look closer!" Adrien demanded.

"Dude, I don't even see anything!" Leroy hissed, glaring at the ball.

"Don't you see Plagg lazing around inside?"

"Nah, it's just a solid black ball to us." Leo retorted, tapping the black ball that layed on the desk.

"Hey, stop. Four-Eyes." Plagg lazily said, closing his eyes. "I'm a delicate ball right now, handle me with care."

"See?! He just spoke!"

"I don't hear anything," Leo said. "We don't hear or see anything."

Adrien sighed, "but he really is in there!"

Marinette clamped her hand at his shoulder, "look, Adrien. It's not like we don't believe you, we're just being sincere that we can't see anything." She worriedly said, "maybe it has to do something with your connection to him?"

"That is quite true," Abigail said. "No matter what happens, he's still the chosen one and he's still connected with Plagg."

"So..what do we do to bring him back?" Leila queried.

"Adrien, you can hear his voice, right?" Marinette asked.

Outside, Leo raised a saw. He rolled up the sleeve of his suit's jacket, "either way. If the man of Sloth can't get out of the ball, we just have to break this black ball, right?" He cracked his knuckles and held the saw, "this is just another warm up for me then.."

"L-Leo! Careful not to hurt him!" Adrien freaked, "Plagg is very sensitive!"

Plagg took a scared stare at the saw as Leo's saw touched it, he blinked twice and began uncomfortably whimpering, "uhh.. uhh.. uhh.."

"Plagg, tell us if it hurts!" Adrien said, thus this made Plagg literally freak out.

"GHINYAAAH!!!~~" He cried out.

"Plagg, we haven't even done anything yet!"

"Wait! Leo, stop!"

"Huh?"

"That's not it.. this isn't the right way to get him back," Adrien said.

"What do you mean?"

"Adrien..?" Plagg stunned.

"Thinking simply.." Adrien snatched the saw from Leo, "I should be the one who'll do it!"

"Sure thing. Always nice to have back-up," Leo pulled out a large hammer that he carried behind his shoulder.

"I-I'll do it!" Adrien enacted a scene, "I'll do it with my bare hands!"

"That's not really the point here.." Plagg shrieked, trembling majorly.

Suddenly, screams were heard from Plagg. Afterwards, he ended up laying inside the ball in a prostrated position.

"Well, that didn't work." Leo sulked shamefully as he held his broken hammer,  "my hammer even broke."

"Well, maybe we're going about it wrong..?" Adrien scratched his nape.

"Maybe so.." Leo shrugged, "you can leave now if you want. Renartha probably has ideas, she can help you."

"Thanks, dude!" Adrien brought a fist out, preparing for a fist-pump.

Leo glanced at it and gladly smiled, "you're welcome!" He fist-pumped with him, but his ring abruptly flashed and caused Adrien to pounce away.

Adrien crashed on the bushes, (yes, they're in the garden. 😊) "A-Adrien, you alright, dude?!" Leo dashed to him, "I am so sorry! Now get up before Abigail kills me!" He pulled Adrien's leg and dragged him from the bushes.

"LEEOOO!!"

"Meep."

°•○°•●°•○°•●°•○

"Man, I hope the place is easy to find." Adrien said, riding on a subway to the destination.

Plagg yawned, "look, you don't have to worry about anything. I'm sure the place will be nice and comfy!" He oozed, dreaming of Camembert. "And with cheese!"

"We're going there to get you back! Not for cheese." Adrien snapped, shoving the ball into his bag.

Marinette who ate at the dinning room with the others, sighed. I wonder when's Adrien's gonna come back, I hope he's alright..

Just then, she realized the others staring at her with confused and shock faces. She blinked, "what?"

Leo stifled a laugh, covering his face with a hanky. "Nothin',"

Everyone there were holding their laughs as much as they can, Abigail tried to eat, but just ended up giggling. Followed by the others laughing as well, leaving Marinette instilling confusion.

"Seriously, what?"

"You miss Adrien already?" Leroy chuckled, "your thoughts are way too loud."

Abigail nodded, "yeah."

Marinette blushed, "why did it have to come to this?"

Adrien took a weird stare at the place, it was nothing but a normal apartment-like building. He reached his hand out for the door's handle, but it opened by its own, revealing then a voice that Adrien wasn't familiar with.

"Welcome back, Rena-Rena! I have something important to report to you, Renartha. I broke one of your precious, precious dolls, you see." The door eerily opened, "but that's because...I keep telling you not to leave your things where I can reach them."

A dark and purplish dressed up headless doll was shown from the door, making Adrien squeak. "Seeeeeeeee? Look! Her head...popped cleeeeean off, didn't it~?"

Adrien gulped in fear, this guy is crazy! Of all things, this is the guy who actually runs this store?!

"But it's all right.. because I melted her head into a special juice for you!" The door slammed open as it abruptly pushed Adrien, making him fall down the staircases and land his butt on the floor.

It revealed a lofty man who had dark blue hair, wearing a unique black labcoat. He had a straw clinged in his mouth, holding both of the doll and a pink purplish liquor stored in a beaker in his possessions.

"Now you can be one in both body and soul with her!! Cheers!" The guy laughed crazily, freaking Adrien out.

This guy losted his buttons!

But once he looked down to see Adrien, he paused, still offbeatly grinning. "Who the hell are you?" Both of them simultaneously said.

The guy yawned as he took off his labcoat, revealing him wearing a black bolo tie with a vintage porcelain of a black swan netsuke, (the black swan miraculous!😀) and white dress shirt with rolled up sleeves, black dress pants and dress shoes.

"I wasn't expecting costumers or visitors today, Renartha must be lucky.."

"This place is more like a general store than an antique store." Adrien looked around, everything was normal. Nothing antique or ancient at all. There was no specialties for kwamis.

Is this really the place I'm looking for? Adrien thought and stared at the guy who observed the liquor he possessed, so he's not the one? Thank god, I never liked these types.

"Um, is this place, well.."

"Renartha isn't here right now. She's busy doing something with her collection of dolls or whatever." The scientist said, not bothering to make eye-contact.

"Renartha? Oh,"

This is the place. He thought.

"Uhh, by any chances, are you..uhh, a friend of hers?" Adrien awkardly asked.

Thus the scientist turned, "huh? Me? A 'friend' of that gal?" His face turned sour, "that is so gross.."

"Huh?"

"Well, how about you?" The scientist asked, "are you another one of her servants?"

This made Adrien's blood boil, "I am not!!" He then calmed down, "I am just an acquaintance of hers named Adrien Agreste, I..sorta bumped into her. although, if I told you how, you wouldn't believe me."

"Alright, alright. I don't even mind a person's suspicions," the scientist said. "So, Sammy Haphelle--"

"Who?! My name is Adrien Agreste! Every syllable was wrong!"

What is wrong with this guy? Adrien thought. He's way too weird. Yet he seems familiar.. could he be..? No, he seems untrustworthy. He won't be a guardian if he's that frolick.

"Hm? Adrien.. Agreste..?" Suddenly, the scientist rummaged into a pile of papers or files from a desktop.

Then he swiveled around with a gleeful face, "Welcome! Welcome to my research laboratory!" He forcefully dragged Adrien and pushed him down a seat. "Now, now! sit down, Mimir Rozen!"

"My name is Adrien Agreste!!"

"It's time...for the doctor...to perform...a little experiment." The scientist grabbed another liquor stored in a beaker from behind, throwing another beaker to Adrien.

He luckily caught it, or else he'd be the one paying for it. He sighed in relief, but alas, that sentiment of relief couldn't last long.

"Here, have some tea!" The guy giddily poured the liquor on Adrien's empty beaker.

"What in the world is happening?" Adrien was so confused, he was sulking pretty bad.

"I welcome you, Chat Noir!"

"Now you remember my name?!"

"Nah, I just saw it on Rena's agenda!" The scientist took a sip of the laboratory tool with his straw that usually hangs in his mouth.

"Agenda?"

"Rena keeps a list of her acquaintances and friends." The incredibly tall guy retorted.

Please don't tell me this Renartha-girl forgets people's names as well! Adrien thought.

"Now, now! Cheers, Breonna Dantés!" The guy banged his beaker onto Adrien's.

"Dude, that's a girl's name!"

The guy sighed despondently as he had a numb impression plastered on his face, "hmm, I'm not good at remembering people's names. There's not much meaning to it." He pulled out a marker from his coat's breast pocket, he sighed. "This is a dark day for America.."

"What in the world are you talking about?! We're not even in America! This is France for pete's sake!"

"hmm.. Adrien Agreste, huh?" The guy then started to write something on Adrien's forehead, "Well, that sounds the familiar."

"H-Hey! What the hell are you writing?!" Adrien freaked. "More importantly, what do you think you're doing?!"

Soon, after it's done. The guy cackled, "there we go!"

"He wrote on me?! What the..? Did you just.. write my name on my forehead?" Adrien pushed his bangs up to see the writing using a mirror, "how the heck am I supposed to hide this from Marinette? She'll definitely laugh at me at this rate.."

"Welcome, Adrien Agreste! Ahaha hahaha!" The guy laughed.

Adrien pushed his bangs down and turned to the scientist, "hey, aren't you..the guy who said to eradicate me?"

The guy swiveled around and slithered a smirk, "Réne Jekylland Rousseau, Black Swan of the Guardian Council. Currently 23 years old.. I'm sort of a scientist. Sort of a scholar. sort of a researcher. But I'm a philosopher! My specialties are kwamis." He enthusiastically blared, "Réne Jekylland Rousseau. That's my name, boy! You know, my label. Call me Doctor...or Réne...Ren. Jekyll. Reny. Whatever you like, really. Those are the symbols that denote me as an individual.. or at least the others other than the abbreviated ones, of course."

"Wait, weren't you the serious type?"

"Nah, I just acted all serious and impassive, 'cause Renartha would've broke me if I didn't stay silent."

"Why? I mean, she's your twin, isn't she?" Adrien concerned, "she wouldn't do that, right?"

"Well, yeah. She could. I mean, if you had a girl twin, wouldn't ya be bullied by her?"

"What are you saying?! I do have a girl twin! And her name's Abigail!" Adrien freaked, "she's actually one of your associates!"

"Yeah, yeah. But more importantly--"

"Reny!" A voice called as they turned to see Renartha, having a kind smile, resting herself on the stairs' hand drills.

"Welcome back, Rena-Rena!" Réne waved.

As soon as Rena jumped down, Adrien expected them to have a warm welcome of a family reunion to each other. But Renartha suddenly kicked Réne's butt, but he just smiled happily.

"You idiot! I told you, I told you a hundred times! Don't come in without permission!" Rena's blaring eyes didn't seem to frighten her brother, "and where the hell did the head of my dear Violeta go?!" She pushed the headless doll onto Réne face.

Réne chortled as usual, "I'm not even gonna try bringing to you this, but it's your fault for putting something you value in my reach.. you always knew that I have spare keys back at home," he laughed, "nice doll collection by the way!"

Renartha was about to release a wave of madness in her, "you...idiot!! Shut up and die 'till you die and 'till you die!" She tried to kick her brother several times, but he kept dodging it. "Once I tell mom of what you've been doing, barging in someone's property, you are so dead!"

"Uhm, are you..Renartha?" Adrien queried, interrupting the scene.

Rena turned, "Renartha Aurea Rousseau, White Swan of the Guardian Council." She glanced right back at her brother, "who's this?"

Please don't tell me she's another sociopath!

"I dunno. Another random kid. ha! Just kiddin' this is...uhh, Adrien Agreste!"

"The Chat Noir? One of the Twin Hearts? This is Abigail's brother? He's short."

"Who're you calling short?! We have the same height!"

"So Chat Noir, what business do you have in my store?"

"Well, I--"

"Well, I, what?" Réne interrupted, "Doesn't matter of what's the purpose he has to come to your store." He slammed his hand on the desktop of the counter and leaned closer to Adrien. "We obviously already know the answer, he wants something. Soooo, it doesn't matter... cauuuusee..."

Suddenly, he jumped in, tackling over Adrien. "NOW, HURRY!! HURRY!! HURRY!! LET ME TOUCH YOUR KWAMI!! LET ME EXAMINE IT!! LET ME EXPERIMENT ON IT!! GIVE ME A SPECIMEN!!" He exclaimed, "WHERE IS HE!!? HE'S THE SLOTH, ISN'T HE!? THE BLACK CAT!! THE LEGENDARY BLACK CAT OF SLOTH!! WHERE?!"

"Uhm, uhh.. well.."

"WHERE IS HE!!? WHERE!!? WHERE!!? WHERE!!? WHERE!!?"

Once after Adrien showed him Plagg, who was in the same black ball as usual. Réne blinked, "THIS IS HIM!!!???" He pointed as he freaked out.

Renartha held her chin, "Whoa, I've never seen this before.."

"Uhh, we're..finding a way to bring him back to normal," Adrien awkwardly said. "He's been through a lot, that's why I came here to ask for your help.."

"My help? Heh, I don't really know how to fix one of these." Renartha said, "but I guess brother and I'll give it a try."

"Oh, I have tons of ideas!" Réne exclaimed, "I AM SO GRATEFUL FOR THE WORLD'S MYSTERIES!! NOOOWWW!! NOOOWWW!! GIVE HIM TO MEEE!!"

"I COULD BREAK THE BALL WITH A HAMMER!!"

"Uhh, sorry. We already tried that.."

"THEN I'LL USE A WRECKING BALL!!"

Adrien blinked, "haaah? N-No! Plagg's inside the sphere! He could get hurt!"

"OR I'LL USE 10,000 DEGREES OF HEAT TO MELT THE BALL!!"

"Hinyaah~~" Plagg fainted with a faint voice.

"G-Gah, hang on there, Plagg! I swear I won't let him do stuff like that!" Adrien stammered.

Réne then grabbed Adrien head, "come on! Into the laboratory!" He threw him over to the mirror, Adrien expected him to crash on it, but he ended up passing it like an evolving door.

"Huh?" Adrien blinked and turned, "an revolving door?!"

Réne appeared with menacing eyes from the evolving door, "now, now.. who wants to play with the doctor..?"

Adrien shrieked, but Rena pushed him down. Causing the male to land in front of Adrien in a prostrated position, "you idiot! Stop freaking him out! Treat him with kindness!"

"Alright! Alright! just don't keep stepping on me!" Réne stubbornly recovered, "yeesh! What is wrong with you?! You treat me like Leo or something!"

"THAT'S BECAUSE YOU'RE OVERLY DRAMATIC!!" Rena screamed.

Adrien plugged his fingers on his ear holes, "uhm, can we..get to bringing back my kwami?"

The Rousseau Twins glanced at each other and blinked, "Y-Yeah,  yeah. We should." Rena awkardly recovered.

Réne did as well, "right.. forgot all about Sloth," he walked to some test tubes and mixed them up in a beaker.

"So your kwami got trapped inside a ball?" Rena asked, reading a book as her doll-like kwami rested on her shoulder. "How?"

"Uhm, long story. I didn't quite noticed his actions before, but due to his words.. he said he was exhausted and can't fight on," Adrien said.

"Did you fed him?" Réne asked, stiring the beaker with a random teaspoon.

"Yeah. Just yesterday," Adrien said. "He had like..three wheels of Camembert. Although, he seemed to be quite tired before eating that.. after he ate it, he just said he was hungry as usual and went back to sleep. Yet, he did say that he's still exhausted."

The Rousseaus glanced at each other, "tummy ache?" Rena implied, referring to her brother.

"Maybe," Réne shrugged.

"Whether if Plagg doesn't come out of the shell, Paris will be in danger." The kwami from Rena's shoulder said, "the prophecy of the Twin Hearts won't be fulfilled with that way."

A black kwami, with feathers popped out of Réne's back collar. "Plagg is broken if we don't get that fixed," he sighed. "Ladybug and Tikki won't be able to hold it long.."

"What do you mean?" Adrien queried.

"If one of the Twin Hearts' miraculouses are broken, such as yours. The other one will get weak and die. That means, your Buginette will die." The kwami ate a juice box from Réne's pocket, "it's just like the bond between the kwami and the wielder."

"I don't really apprehend with any of this,"

The kwami sighed, "you want a demonstration?" Strings came out of Réne's back collar and snatched Adrien's ring from him.

"H-Hey! What're you doing?!" Adrien cried out as the strings placed down the ring gently on a chair adjacent to them.

"Réne, do it as you please, with all your might." The black swan kwami implied, pointing at it.

Réne stared down at it with a decurved position, "what's on this little thing anyway? Does it have black substances or something?"

"Whoa, what are you trying to do?!"

More strings came out of Réne as they wrapped around the Chat Noir miraculous, he raised it and threw it down. Emitting a boom as it crashed on the chair.

Adrien blinked, so did Plagg, they were both sweating rapidly. The miraculous was still functional, there was no scratch at all, not single one. But the chair is very broken and there was even a large dent on the floor.

"I knew it," Plagg lazily muttered, unfortunately, Adrien heard him loud and clear.

"Liar! You were scared as me!"

"See? If the chain of trust is breaked, then the item would be easier to break. If the seal breaks, The wielder will begin to experience abnormalities on their bodies such as numb limbs, palpitation, shortness of breath, nausea, dizziness, headaches, stomach-aches, dry eyes, and dry skin. After all those conditions, the wielder will eventually die."

"Belk, watch what you're saying.." Réne said, prompting a honed glare at his kwami.

Belk, the Black Swan kwami nodded, "yes, Master."

"S-So.. Marinette, will die..?" Adrien's eyes fell and then had a serious face in him, "how do you release Plagg?"

Réne blinked, "oh my god, you really are in love with her." He handed him the beaker, "stop thinking. Drink this juice and relax for a bit,"

Adrien took it, "thanks. I needed to cool down a bit," he drank his juice.

Réne sat in his chair, mixing other liquors together in a beaker.  He sighed, "I'm not sure how to get Sloth back, but I guess it's worth trying out this method on you.."

"Huh?" Suddenly, Adrien's vision became blurry as he spaced out. "Wh-What did you make me drink?"

Réne swiveled and insanely laughed, "just a drink that would make you enter your kwami's mind! Haha haha! "

Adrien fell on the floor in a prostrated position, Rena sighed. "You're as rough as usual, brother.."

"Not rough. Just wanted to help him," Réne said, picking Adrien up and placed him on a chair. "He should wake up after five hours, close the store already. We don't want costumers to freak out to see a man like him all asleep, they might think of us of something."

"Good point,"

Rena surged her ankle on the ground as piano tiles appeared. She stepped on tiles, playing a song as the store's doors and window closed. The store's ceiling lights and lamps closed, the store's general supplies morphed into antique supplies. Once Rena stopped playing, she took her foot off of the tiles as they disappeared without a trace.

"You seem quite good today, have you been practicing?" Réne queried, pulling strings as if they were a violin's form of strings.

The beakers and test tubes flowed and returned back to their rightful places. "I didn't. I always play the piano, I'm just trying to get used playing the tiles on ground than an actual grand piano.." Rena said.

Réne chuckled, "now who wants to play surgery? I'll be the doctor and you'll be the pa--"

"No,"

"Such a killjoy like Abigail and Dante, the operation of seeping the Chat Noir in the mind was a success.." Réne grinned and raked at Adrien, who was fast and asleep.

"If only you were as effective with a scalpel on normal humans, you idiot." Rena said.

Réne turned with a smug face, "in that case, can I practice on you like back in the old days?" He pulled out a scalpel, having a menacing aura.

"Quit digging up the old trauma!"

Back in the Pierre Manor, Marinette was asleep too. She figured if she has nothing to do now, she has to sleep. Marinette.. Marinette.. Marinette.. she heard Adrien's voice in her mind, she gripped on a pillow.

Help.. help.. she then jolted up, screaming.

"What's going on here?" Abigail barged in the room and crawled up to Marinette.

"We heard screaming," Leo said. "This is the second time already," he sighed. "I don't bother using my Sun Authority now."

"What happened? Did you have a nightmare?" Abigail asked.

"N-No. I just.. I just heard Adrien's voice in a dream. Everything was dark and empty, but I could hear his voice. He wanted help," Marinette retorted.

"Do you suppose it's a connection between the Twin Hearts?" Leila queried, "your souls and dreams are connected."

"Did Renartha did something wrong?" Leroy asked.

"No, that's impossible. Renartha has her responsibilities," Abigail said. "Although, if Ren was there.. he'd.." she raked behind to exchange glances amongst the guardians.

"It's Ren, isn't it?" Leila said.

"Well, that guy does the craziest things.." Leo said, "he's obsessed with magic and kwamis. But, I don't think he'd do something bad."

"Should we come and get Adrien?" Marinette asked.

"I don't think so," Leroy said, "well. I guess we should, but I just feel that something's wrong about that."

"Marinette, you come after him." Abigail demanded.

"What?"

"As a Twin Heart, you should go! Go save your husband!"

Marinette blushed, "b-but I'm all alone! Tikki and I won't be able to find the place on time."

"Leo, you come with her."

"Haaah?"

"Leo will be your bodyguard, he's always the bodyguard material anyway." Abigail said, "plus, he knows the address more 'cause Réne and him were childhood friends."

"Ohh, You have babies, I love gravies, Who has rabies? Rena-Rena has rabies~~" Réne sang playfully while pouring different types of chemicals in a beaker.

Eventually, Renartha stepped on his head. "Who the hell says I have rabies?!"

Réne moved his noggin away and sat up, "well, seeeeeeee yooouuu!" He opened the entrance door, peeking Rena at the door before leaving. "I have to buy something from the groceries! So don't worry about meee, Rena-- agh, oww!"

Rena thrown a book over her brother's head, but so, Réne laughed. "Like I care, go disappear!"

Done! Pretty sure you guys didn't like it that much. You guys want more Adrienette, do ya? *sigh* I can't really think of something nowadays.
