A week after the reveal, and Plagg stealing all of Marinette's attention, TIkki and Adrien both agreed that they needed to keep Plagg away from Marinette at all times. Sadly for them, it was harder than they could have ever imagined, especially if Marinette wanted to be with Plagg. They were sitting in class, listening to Mme. Bustier drone on and on about the tales of the Odyssey.

Said teacher just raised an eyebrow at how her students describe her teaching methods. Every student just looked away and whistled nonchalantly, trying to avoid her gaze.

When Plagg decided on his grand master plan. He liked Marinette, he really did, but the girl was too sweet and kind for her own good. He wanted to show her the best part of life, the good part, the part about mischief. And that was his master plan. He was going to corrupt Marinette Dupain-Cheng.

Adrien gave a very nervous gulp at what his Kwami just said, he loved his pure and sweet innocent girlfriend, but he shudders to think what would happen if Plagg is ever given the chance to corrupt her. Unnoticed by all, Alya is looking at the scene in deep interest, somehow finding the prospect of turning Marinette to the dark side very tempting.

Plagg slithered his way into Marinette's purse, and upon seeing a sleeping Tikki, he took the red bug, and laid her into Adrien's bag. He snuck back into Marinette's purse, and looked through her phone. Her father had recently texted her to ask if she had any plans after school, and if not, if she could watch over the bakery for an hour. Plagg replied for her, saying that she was sorry, but she was going to be busy for a while.

This time Tikki didn't even try to hide the irritation showing on her face, not only did Plagg had the nerve to corrupt her chosen, but he also had the nerve to swap their places again!

'Oh! When that little ink blot wakes up I'm going to shove a whole wheel of cheese filled with orange juice down his throat!' Tikki thought with maliciousness.

When the bell rang, excusing them for class, Plagg was grateful to see Adrien was going to be busy talking to Nino, and Marinette was the first out the door, making her way to the library. Once inside. Plagg zipped out and hugged her cheek.

"Princess!" exclaimed Plagg.

"HEY THAT'S MY NICKNAME FOR HER YOU INK STAIN!" Adrien shouted in irritation, that little devil has some nerve to use his nickname for her.

Marinette squealed lightly and hugged him back, "Plagg! What are you doing here with me instead of Adrien? And – where is Tikki?"

Plagg waved his paw lightly, "Details, kit, mere details. Now, I know you don't have any plans for the rest of the day, sooooooo… I was hoping you would have some fun with me!"

Marinette giggled, "Depends, what does the kwami of destruction and bad luck find as fun?"

Plag snickered evilly, "Weeeell, Adrien's going to be changing for his fencing lessons soon~ Why not start there?"

Adrien felt a chill run down his spine at what Plagg is planning, and what's worse he's using his Lady against him!

Marinette sighed happily at the thought of being able to watch Adrien while he was fencing, but then she froze at the realization that that could NOT be what Plagg meant.

"You're not suggesting we go watch him, are you?"

Plagg snickered and pat her head comfortingly, "More like the complete opposite."

When they entered the boy's locker room, Marinette had Plagg scope it out first, to make sure there were no boys changing yet. Plagg gave her the okay, and they went up to Adrien's locker. Marinette smiled at him, "You know the combination?"

Plagg blew a raspberry, "Combination? Pfft! Get outta here!"

Plagg flew straight into the locker and opened it from inside. When the door swung open, he was floating there, giving a light bow.

"Thank you, thank you very much." (Plagg did an Elvis Presley)

The class chuckled at what the kwami did. Unfortunately (Fortunately for some) their laughter turned into silence as their jaws dropped at what Marinette did next.

Marinette giggled before she reached in and grabbed Adrien's fencing helmet. She then pulled out a picture of herself in a Chat Noir themed bikini. It was from last summer when she and Alya went to a pool party. Alya had worn a once piece that was Ladybug themed, and to match, Marinette went with the Chat Noir themed one. She could have gone with the one piece, but she didn't like the design on it, whereas the bikini was perfect for her. It was small and black, with a transparent green layer on top that had black paw prints and said "Purr-incess~" She handed the picture to Plagg, who didn't even look at it, knowing better.

She handed him duct tape as he taped it onto the inside of Adrien's helmet, that way when he puts it on, it would be all he saw. The 2 put the helmet back inside as the fencers started to pile in. They hid behind the door, waiting for Adrien. When Adrien finally came in, the other fencers were already changed and had left, thankfully for the 4 of them. Marinette and Plagg stayed hidden and started to watch. Adrien opened up his locker and Tikki flew out of his pocket. She looked inside the locker before shaking her head.

Silence once more echoed through Fate's domain as the class could not believe what they had just saw. They never could've imagined their shy and sweet class president could ever wear a bikini, and make it look so attractive to both boys and girls. For Adrien his mind had shut down. He had always pictured his Lady in that red latex suit of hers that hugged her figure quite well to be very provocative on his primal male side. But seeing that picture of her in a very revealing swimsuit with his nickname on said swimsuit made his nose bleed quite a bit as well as feeling a tightening in his pants. To Alya, she was shedding tears of joy, while she loved her pure and innocent girl, seeing her becoming quite daring made her want to turn her universe's Marinette into that universe's Marinette.

"He's not in here. You know what, he's probably with Marinette. That would explain why I woke up inside of your bag."

Adrien nodded and started to get changed (Plagg silently laughed as Mari turned bright red and looked away).

"I hope Mari's fine with watching him. He's lazy and annoying a lot, but for some reason he likes her enough to be nice and caring…"

Tikki giggled, "He doesn't show it till it actually happens, but he actually has a soft spot for babies and human girls."

Adrien nodded and finished getting changed, and Plagg gave Mari the O.K. to look. They watched happily as Adrien closed his eyes as he put on the helmet. When he started to lower his arms though, they froze, and his entire body went stiff. The 2 trouble makers smiled at the sight. His eyes had opened.

Normally everyone would laugh at Adrien's situation, however they honestly can't blame the guy, because seeing that picture of Marinette in a bikini would cause everyone to react the same way if they were in his situation. But Alya's a special case, she didn't hide her enjoyment of the prank much to the blonde's still red face, either from anger or something else.

"Adrien?" Tikki called, "What's wrong?"

A second later, Adrien threw the helmet off and away from him quickly, turning beet red as he backed up quickly to the wall. He pointed at his helmet and started to sputter indignantly.

"T-the- tha-a-at! N-not mine! Nononononono, how did-?! Why?! W-when?! Wha-MEEP!"

Tikki watched confused before she floated into the helmet.

"What the-?!"

She came over to Adrien and held the photo up to his face, while wearing a teasing grin.

"Woooooow Adrien. Didn't know you liked her that much~"

"IT'S NOT MINE!"

"Are you sure about that Agreste?" Alya said not bothering to hide the enjoyment she's getting from Adrien's reaction. Honestly now she knew why Fate put Plagg and Marinette to sleep, oh how she wishes that's not the case.

Plagg and Marinette zipped out to let out their laughter. They gave a shaky high five, as they made their way to the bakery.

Tikki giggled, "I know, just teasing. But who put it in your helmet?"

Adrien stood up slowly and shakily, "I don't know, but they obviously know about my feelings for Mari…"

Tikki nodded lightly, "So it could literally be anyone…"

Adrien sputtered, "W-what?!"

Tikki giggled, "You're lucky Mari's as dense as you. In the past week, you've given Marinette more attention than Chloe could give you in a lifetime. You spend every possible second you 2 have, flirting and touching her. You've yet to realize what you did this morning!"

Adrien gulped as he started to grab his helmet and put it on. "What did I do wrong?"

Tikki scoffed, "Nothing, nothing at all. Oh! But you may or may not have kissed her cheek in front of the rest of the class. I was surprised that Chloe didn't have an aneurysm."

"HEY!" was the response from said Q.B. Blonde. The rest just ignored her just keeping silent in order to not miss any interesting parts.

Adrien was grateful he wore the helmet, otherwise Tikki would see how he had somehow gone redder than her. Right before Adrien was about to close his locker, his phone received a message. Tikki poked her head out.

"It's Marinette!"

Adrien immediately answered, "Hello?"

"How's my knight in shining armor doing?"

Adrien chuckled, "About to head into the gym for fencing. Wanna make sure my skills are intact for when I'm protecting my beautiful Princess~"

"Awww~ that's so romantic~" Rose said dreamily, the rest just nodded along wanting to see more. Meanwhile Fate is smirking beneath his robe, clearly awaiting the moment where everyone would either pass out or their brains would shut down indefinitely.

Back in the bakery, Marinette was laying on her bed, watching as Plagg looked over a list of prank ideas, deciding on what to pull on his chosen next. Marinette pet his head gently.

"Aww, how cute~ speaking of which, I was wondering if you could come shopping with me in an hour. Alya's busy, so I need you to come instead and give your opinion."

When Marinette said that, Alya's scheming brain went into overdrive. If she thinks what Marinette is thinking then boy is Adrien going to be one poor unfortunate soul. And at the same time one lucky son of a gun.

"Sure." He said, "By the way, do you have Plagg with you? I think he switched places with Tikki while in class."

"Yep, he's right here. I'll bring him with me to the store, so we can trade off."

"…Marinette… Did you and Plagg go into the boy's locker room by any chance?"

Marinette tried to hide her giggle and faked innocence, "Why would I do that Chaton? You do realize I'm a girl, right?"

"Yeah, for shame Agreste. Making quite an accusation on your own girlfriend~" Alya teased, relishing the irritation on his face. She has to say she is liking where this universe's headed and if her theory is correct then she will ask Fate if he could make this 'What if Universe' into a definite one.

She couldn't hide her giggle when she heard Adrien sputter something incoherent, before calming down to speak quickly.

"OKAY! I'll c-come by in an hour BYE!"

He hung up, and Marinette burst out laughing. After laughing for a bit, she smiled down to Plagg.

"Made your decisions?"

Plagg nodded excitedly, "I don't know why you're not Chat Noir and Adrien's Ladybug. You obviously take my talents as a civilian, whereas Adrien's so sweet and innocent, his nickname is literally cinnamon roll!"

"Now THERE'S a thought! Just imagine Adrien, you as Ladybug or Lord bug in this case, and sweet and pure Marinette as Kitty Noir in a very tight form fitting black latex suit, that will probably show off her assets~" Alya purred to Adrien, said blonde model is now currently trying to cool himself down because of Alya his brain is now going into forbidden territory. He could only imagine seeing Marinette as Chat Noir, it's leading to a very risqué mindset.

Marinette giggled before looking over Plagg's choices. She smiled at one that Plagg had circled and had arrows pointing towards.

"Looks like we had the same prank in mind as well~"

An hour later, Adrien walked into the bakery, TIkki inside his pocket. Sabine rushed over and hugged him happily.

"Adrien! Just in time too, I just finished a batch of buttery Croissants."

Sabine laughed as she saw Adrien's eyes light up happily, with stars shining brightly. Marinette came down into the bakery a minute later, to see Adrien standing next to Sabine behind the counter, mouth filled with the buttery goodness of her mother's croissants. She giggled and came over. After saying goodbye to her mother, the 2 of them left, to head out to the mall. Once there, Adrien looked around at all the clothing stores inside.

"So, what are you looking for?"

Marinette hummed lightly as she walked ahead, "A new bathing suit~"

Adrien stopped dead in his tracks. Still as a statue, yet red as Ladybug's suit. Marinette looked back to him in innocent confusion.

The same can be said for the present Adrien as well as every male in the group except Fate, once again remembering the picture from earlier. Like the other Adrien he went stiff (In more ways than one) and tried to cool himself down. Alya meanwhile was crying tears of joy, being so proud that her innocent girl is now growing up into a femme fatale that would probably be the one who's wearing the pants in the relationship.

"What's wrong?"

Adrien came back to reality and laughed nervously, "N-nothing! I was just surprised is all I didn't expect you want to go shopping for a bathing suit is all especially with me! W-why do you need a bathing suit?"

Marinette walked up to him and started digging into a bag she had over her shoulder.

"I would normally just wear the one I got last time, but…"

Marinette pulled out the bikini from the photo, and Adrien was certain that he was going to pass out.

"HAHAHAHAHA!Oh my GOSH! She's torturing the poor guy!" Alix laughed out loud, she was clutching her stomach in laughter, some of the others agreed with her and laughed as well. The way Marinette was acting felt like torture to the poor blonde boy.

"The top is too small for me now, and I haven't learned how to correctly design bathing suits, so I can't fix it yet. It's a bummer really, I liked this one a lot. It even has my pet name on it!"

Adrien had missed that in the future, but now he saw it. He saw how his nickname for her was stitched on the bottom piece, and he couldn't take it much longer. Marinette put the bikini back in the bag before shrugging innocently with a shake of the head.

"Well, I guess I'll just have to find a good enough replacement. But don't worry-"

Marinette leaned closer to him, "-I'll be able to fix it soon, and then you can see me wear it whenever you want me to, come this summer."
Welp goodbye world. Adrien's soul died happily and went up to heaven.

The prime Adrien is thinking of joining himself in the afterlife. That Marinette will kill him someday. He clasped his hands together and prayed that his Marinette won't become like that, he loves his pure Angel Marinette. He doesn't wanna die by evil seductress Marinette. Meanwhile Alya and most of the girls in the class were praying in the opposite way, while they love their pure of heart Marinette, they really want to see what succubus Marinette can really do.

The first shop they came upon, was called 'Evengelenes Choice'. When they entered, Adrien looked around at the people there, and he knew what he had gotten himself into. The store was filled only with clothes for females, mainly young women. There were 5 other guys in the store, but they all looked depressed or dead as they carried multiple bags and clothes for their female companions, who seemed to be having the time of their lives. Adrien gulped as Marinette grabbed about 10 different bathing suits, and dragged him towards the changing areas. When she came out wearing the first bathing suit, he had almost died on the spot again when he saw her wearing a tight Ladybug themed one piece. Marinette laughed at his expression before turning to walk back inside the changing room.

"Careful Adrien, it looks like you're getting a nosebleed."

"Too late for that! HEHEHE!" Alya giggled at their Adrien's face or more specifically his nose.

Adrien knew she was joking, but he checked anyways, while he swore he heard Plagg laughing from inside Marinette's bag… inside the changing room. Adrien jolted up and knocked on the door repeatedly.

"Princess open up please!"

A second later, the door opened a crack, and Plagg stuck his head out, with paw in front of Adrien's face like a stop sign.

"Sorry, but the Princess is in the middle of changing. What are you, a pervert?"
Adrien glared at Plagg, "That's just it! Why are you still in there? You're male, and Marinette's in their changing!"

Plagg shrugged, "I'm not even the same species as her for 1, and for 2, and unlike I'm sure you would, I'm not ogling at her naked body while she's putting on a bikini."

"Hmm~ perhaps Adrien was hoping at getting a peeeeeeak~~" Alya said, although Adrien didn't hear for one thing, the way Plagg described about not ogling at her naked body caused his head to go somewhere else.

Adrien turned beet red, causing his kwami to laugh as he floated back in. Tikki flew out and shook her head.

"That idiot…"

When Marinette came out again, she was wearing a violet bikini with white and multi-colored purple butterflies. Adrien made an X sign with his arms.

"Absolutely not. As much as I adore your sense of style, I will never allow you to wear anything with butterflies on it."

"Agreed." Adrien said, agreeing with his other self, as much as he loved Marinette's sense of fashion, he had taken a big disliking on anything with butterflies on clothing.

Marinette rolled her eyes and changed back into her normal clothes, when they left the store not buying anything, Marinette look out a small piece of paper. Adrien looked at the list.

"What's that?"

Marinette looked around for a certain store, "A list of stores Alya told me to search in. She told me to go to one in particular, called 'Laura's Lingerie'. It should be somewhere on the west side of the mall, c'mon.

The moment that name came out of Marinette's mouth all the guys in the room went stiff and red in the face, while the girls except Mme. Bustier started 'whooping' and squealing. Alya most of all started to shout encouraging words towards the screen thinking that the Marinette there would hear her saying 'How proud she is of her', that she's all grown up that she's taking her man Lingerie shopping hoping to get a rise out of him.

The second Adrien heard the name of the store, he went as pale and stiff as a statue, if you don't know why, then read the second word in the store's name. Adrien stared at Marinette with his jaw dropped. Why on earth would Marinette want to go there?! When he followed her into the store, he wasn't surprised that the state of the men here were the same as they were in the last store, the difference being that they were deep red in embarrassment, and were trying to hide their faces. Adrien didn't blame them. He felt even more embarrassed though, due to him and Marinette obviously being teenagers, someone could easily get the wrong idea. Marinette grabbed only 3 bathing suits this time, and led him over to the changing room. When inside, Plagg came out of her purse, the 2 smiled evilly, as Marinette glance at the kwami.

"So far, this is going amazing! Who would've thought he could get even redder than TIkki."

Plagg snickered, "What are you planning on next kiddo?"

Marinette thought with a small hum before a devious smile spread on her lips, "Wait until I put on the first choice, and then watch as he becomes a walking tomato~"

Plagg cackled as Marinette got changed, "I like the way you think kit!"

When Marinette came out, Tikki was floating next to Adrien, while eating a cookie. When they saw Marinette, the cookie fell to the floor, and Adrien was positive his nose started to bleed. Marinette was wearing another Chat Noir themed bikini, but this one was way worse. It didn't even have straps, so it could fall down if added on the pressure, but Marinette had gotten the smallest size, so it hugged onto her, making it unable to budge. The bottoms were WAY too small for comfort, as the sides that went over her hips were just thin straps. The whole bikini was black with neon green frills and neon green ribbons on the middle of the straps of her hips. There was a neon green paw print on both of her nipple areas and on the back, where the top was held together, it was tied by a green ribbon, much like the ones on her hips. She did a light twirl and smiled at the 2.

"Well, what do you think? I, love it!"

Hands down, every single male human being in the whole room just passed out via nosebleed at the sight before them, however for Adrien by some miracle or just sheer will power managed to technically stay awake even though we're pretty sure his brain went into overload causing Adrien's mind to become nothing but a vegetable. The girls were now laughing and cheering at the boldness of the Marinette in that universe. They cannot believe that when sweet and innocent Marinette becomes corrupted she turns into an evil temptress whose hell bent on drowning Paris in the blood of every male and quite possibly some female via severe nosebleeds. Now Alya is determined that this must be their universe as well, imagine the fun a corrupted Marinette can cause, the sheer anticipation of it caused shivers to run down her spine. After they finished watching this she will do everything she can to corrupt Marinette in the proper way.

Adrien started to sputter uncontrollably, unable to make any words, as Tikki fumed in annoyance.

"Absolutely not! You go back inside that room and change into a more covering bathing suit! No chosen of mine is going out there sporting something that could make a woman in only underwear and bra seem decent! You will not take another step forward missy, so change right away!"

Adrien silently thanked Tikki when Marinette entered the changing room with a pout. When inside however, she turned her back to Plagg, and he quickly tied about 5 knots in the ribbon, so that it couldn't come off. Marinette smiled gratefully and opened the door. Plagg flew out and zipped off, causing Tikki to chase after him to make sure he didn't get into trouble. Marinette waved Adrien over.

"Adrien? Can you help me with something?"

Adrien gulped as he came over, "W-what is it?"

"Oh poor boy~ Marinette will eat him alive at this rate!" Alix said with much support at what Marinette was doing. The girls just giggled and looked at their Adrien who was still knocked out of it with his eyes still open.

Marinette opened the door fully, making Adrien grow red again, as she smiled innocently at him.

"Can you get the ribbon in the back for me? I asked Plagg for help, but he just suggested to rip it off."

Adrien gulped and nodded quickly, "S-s-sure! Umm, could you uh, t-turn around?"

Marinette smiled almost evilly as she grabbed his hand and pulled him into the room, and closed the door behind him. She turned her back to him slowly, and pulled her pigtails to lay over her shoulders.

"Hurry though," She told him in a sickeningly sweet tone. "I want to get to the rest of the bathing suits."

Adrien gulped and nodded quickly, which Marinette knew by his reflection in the mirror in front of her. She looked directly into his eyes as he tried his hardest to untie the knots. When he took a glance up, he stiffened when their eyes met in the reflection. Unbeknownst to him, once their eyes met, the knot was completely untied, and he had to let go of it. Marinette however, saw this coming a mile away, and had put her hands to her breasts, to hold up the top. Adrien turned blood red as Marinette winked at him flirtatiously.

"Welp, thanks for the help pal!"

"OMG! She is killing his mind piece by piece, he won't last for long, and eventually he'll be her slave forever!" Alya exclaimed, the girls can only agree and support the idea, because hell 'Girl Power' even though some would say that this is becoming over the top.

Before Adrien could even understand what was happening, Marinette had shoved him out of the closet, and locked the door again behind him. He laid there in the floor, blinking rapidly as he took in what had just happened. Plagg floated down into the stall and smiles as he saw Marinette trying to hold in her laughter.

"I had no idea he could get so embarrassed and flustered!"

Plagg nodded, "Yeah, now what next? Tikki's going to hound me after this no matter what, so let's go all the way here!"

Marinette and he snickered evilly as they planned their next attack.

"Okay! Why don't we take a break and wait for Adrien and the rest of the guys to wake up and possibly make them think that they've been dreaming. Agreed?" Fate said as he paused the screen. Everybody who's still conscious agreed wholeheartedly. Meanwhile Alya is scheming on how to corrupt her best friend in order to torture Adrien until he begs for mercy.
