Chapter 2: A ring and a duel

Plagg had watched the whole thing go down with Bastion and Lila and he was giggling to himself, he hated Lila, so seeing the brat get busted was fun. He was in the bathroom with Adrien at the moment.

"That guy needs to stop this Plagg, Lila will be akumatized at this rate," said Adrien.

"Who cares, it's not as though it hasn't happened before, besides, she's hurt Pigtails with her bullying, and you haven't done anything about it, some hero you are," he said.

"Plagg, how could you say something like that? I am a hero, if Marinette would just go along with Lila instead of against her things would be ok. But I need to talk to that new guy about hurting Lila's feelings and how he talks to everyone. Who does he thing he is?"

"Someone with the power to stop sausage hair and prove that she's a liar, I wouldn't cross him Adrien, he's probably more powerful than your dad," said Plagg.

"As if. I'm going to talk to him."

"Uh, Adrien, I think that the ring needs a polish, each time I go in there it feels filthy, you think you could spruce it up, like right now?" asked Plagg, he had to get out of here.

"Oh, uh, sure thing, but you've never asked for this before," said Adrien, taking off the ring.

"Hey, even I know when my jewel is dirty," said Plagg with a grin.

Adrien washed the ring and was about to put it back on when there was a commotion outside. He raced out of the bathroom to see Bastion hugging Kagami and Lila was on the floor, Marinette and Chloe were watching in shock and Kagami was holding her sword in one hand. Plagg took the opportunity and grabbed the ring, flying away with it.

"What's going on?"

"She attempted to push Marinette, I lunged at her, shoving her to the ground, using my sword to defend my friend and Chloe saw everything and then I saw Bastion and we hugged," said Kagami.

"Why would Lila attempt to push Marinette?"

"Duh, because she hates her, but Liar-la didn't count on Bastion and I being with her and seeing the whole thing," said Chloe, who was holding onto Marinette tightly.

"I also recorded the whole thing, this proves that this girl is a bully," said Bastion, "I intend to show everyone."

"No, Lila could get akumatized," said Adrien.

"Oh, thank you Adrien and it wasn't like they said at all, I was trying to help Marinette," said Lila, curled up in a ball.

"No, it was like they said, I'll testify as a witness," said Kagami.

"You're a coward Agreste, you can't face the truth." Bastion had his arm around Marinette by now. "No, you're worse than just a coward, you're a dog, nothing but an obedient puppy for his daddy." Adrien turned red with anger.

"Wait, time out! It's not ok for Liar-la to get akumatized but it's ok for Marinette to get akumatized, because that's what you're saying," said Chloe, red with rage.

"You are not the boy I thought you were. Let's go Bastion sama," said Kagami.

"We're right behind you Kagami chan," he said.

"Wait, Bastion, how do you know Kagami?" asked Marinette.

"We knew each other when we were children before she moved to Paris," said Bastion with a smile.

"I thought you didn't have any friends before I looked at your phone, what's going on?" Marinette asked.

"My mother got me a new phone and so got rid of my old contacts and so I really did have no friends," said Kagami.

"Rubbish, you always had me," said Bastion.

"Mother didn't believe that we were worthy of associating with your family," said Kagami.

"Of course, she did," muttered Bastion who sighed and quickly wrote down his number and email for her, "There you go."

"Arigato Bastion sama, you are too kind," she said.

"Kagami chan, I told you, don't call me sama. Kun is fine or even just my first name," he groaned as they all walked away from Adrien.

"I must show respect to my superiors," she said. Bastion groaned and Marinette giggled, asking what Bastion's blood type was.

"I'm the rare AB type, meaning I'm talented, composed, proud, self-centered, charming and creative. Those are just some of the things an AB blood type is," he said. "My dad is A, and my mother is B."

"Oh, that's so cool. Kagami told me that she's an O type, I found out that I'm an A blood type," said Marinette.

"Meaning you're stubborn, responsible, tense, kind, reliable, and a perfectionist," said Bastion.

"Uh, yeah, that's me, among other things."

"What is this blood type thing?" asked Chloe.

"In Japan, blood types are considered an important indicator of a person's personality. It's known as the "Japanese Blood Type Personality Theory," said Bastion. "It's the same as being asked 'what's your sign?" in English."

"Well, that's interesting. One time I was at the doctor's I needed some blood and they said to get O type blood, so what does that mean?" asked Chloe.

"It means you're independent, passionate, jealous, ambitious, ruthless, confident, and energetic," said Bastion.

"That's not what I want to hear," said Chloe, looking down.

"It also means that you're flexible, intuitive, athletic, vain, and a romanticist," said Kagami, "Just like Marinette is wary, nervous, neat and sensitive and Bastion is aloof, mysterious, private, trustworthy and a dream-chaser," she said. "I, myself am an O type, just like you, meaning I am independent, optimistic, strong-willed, and intuitive but also cold, realistic, self-centered, calm and robust."

"Wow, I didn't know any of this stuff," Chloe admitted.

"Let's talk about our birthdays, I'm April 12th, so I'm an Aries," said Bastion.

"I'm the 9th of July, so I'm a Cancer," said Marinette.

"My birthday is November 20th, I'm a Scorpio," said Kagami.

Chloe game her birthday and they finally sat down together in the cafeteria. Everyone stared at the new boy who had the most unusual companions sitting with him. "You know, if we're all, you know…uh, united against that brat Liar-la, maybe we should uh… you know...make a group for us to chat on or…something like that," said Chloe, who was red in the face at her suggestion.

"I like that idea, since you had it, you should start it," said Kagami.

"Uh, I think that Bastion should be the leader, it's because of him that this is happening," said Chloe.

"That's fine with me Chloe, but you'll always have the credit for the idea," said Bastion who created the group on his phone. "Ok, usernames?" he asked.

"Swordswoman," said Kagami, accepting his friend request.

"MDCFashion," was Marinette, with a smile.

"I'll be Deckmaster," said Bastion.

"Um, I would pick Queen Bee but, I…I'm not her anymore," said Chloe, embarrassed, being around Bastion brought out another side of her, a better side, like when they were kids.

"How about SocialPrincess?" suggested Bastion and Chloe loved the name and so their group was made. It was cut short when Lila brought in Mr Damocles and spun her story about Marinette hurting her. Alix frowned.

"Is this true Marinette?" he asked.

"No sir, it's not.

"Damocles Sensei, I have proof that Marinette didn't hurt Rossi at all, Rossi was going to hurt Marinette," said Bastion and he played the video and recording for Damocles.

He watched as Lila came up behind Marinette and shoved her only to be shoved back and held at sword point by Kagami. Then the conversation with Adrien was heard.

"I'm not impressed with the bullying that the students are allowed to get away with. Your school isn't as it is advertised. I'd advise you to do something about it," said Bastion, his arms folded, and Alix frowned even more, edging away from Lila and the rest of the class. With no one noticing she was yanked into a portal.

The Burrow

"What the?" she asked, looking around.

"Hey mini me," said Bunnyx, standing behind her.

"You, you're…"

"Yeah, I know. Listen and watch," she said, showing Alix all of Lila's lies.

"That, that…She turned us against our friend!"

"Can you call yourself her friend?" Bunnyx asked. Alix hung her head. "I'm showing you this because now that Bastion is involved the timeline has changed dramatically. Without him, this would have happened in a week," said Bunnyx and she shows a dead Marinette to her past self. "He saved her life. The future is bright for her now, but she still needs more help. You can help by being a friend and admitting that you were wrong," said Bunnyx.

"I understand, is there anyone else I can get on Marinette's side?"

"Just one for now, simply use your own knowledge to tell Nathaniel about Leonardo not having any kids or even being married, he'll come around, I guarantee it," said Bunnyx with a wink. Alix grinned. "Ok mini me, time to get you back," and she popped Alix back just after she had taken her.

Alix quickly slid over to Nathaniel and spoke quietly to him, he paled, and they both nodded. "Hey, Marinette," said Alix, causing everyone to turn and look at her and Nathaniel who were coming over to Bastion's table. "Marinette, you were right, Lila is a lying, cheating, backstabbing liar and bully and I'm sorry for allowing myself to be taken in by her and I'm also sorry for hurting you," Alix said, she'd taken her hat off and was looking at Marinette with sincerity and there was a sheen of tears in her eyes. "If it wasn't for Misawa sama and his help in exposing her and something bad happened to you, I…" she stopped talking, tears clogging up her throat. "You could have committed suicide!" she shouted, causing everyone to gasp. "I'm sorry, I'm so, so, so sorry, please let me find away to gain your trust back, and then your friendship, because I don't deserve it," she finished, and Marinette stared, and Bastion nudged her. Alix was crying now.

"I can see she's being sincere," he muttered quietly.

"Marinette, I'm sorry I didn't speak up and didn't do anything for you," said Nath, "I was afraid of Lila but that's no excuse for being a bad friend. I understand why Marc doesn't like her now. Alix informed me that Leonardo had no wife or children, making Lila a liar about being related to him and I doubt that any of her other lies were true either. I'm sorry for believing Lila over you. You introduced me to Marc and always tried to encourage me and I was just quiet. I don't deserve a friend like you, but I hope that I can, like Alix, gain your trust back and eventually your friendship, since broken trust is hard to get back. It's like burning the Mona Lisa, it's too priceless to repainted or fixed. I hope in time, you can forgive me," he said, and he had looked Marinette straight in the eye as he said all this.

Chloe, Bastion and Kagami waited with bated breath as Marinette made her decision. "That you so much for your apologies, they mean a lot to me and you're right, I can't give you my friendship and trust back that easily, but I can start forgiving you. Hi, I'm Marinette Dupain-Cheng, nice to meet you both," and she held out her hand. The two smiled and shook her hand. "Is it alright with everyone else if they sit with us?" she asked the others.

"After sincere apologies like that, why not?" asked Bastion and Alix and Nathaniel sat with them, drawing Marc, Aurore, Jean, and Mireille from Miss Mendeleiev's class to join them as well. Bastion was introduced to all of them, and he liked them, and they liked him.

As for Lila, she couldn't believe what was happening, this morning, Marinette had nobody and then some guy showed up and turned her plans to get rid of Marinette upside down. She was given a warning about bullying and a mark on her record for lying to get an innocent student in trouble. She gritted her teeth; she'd get dirt on Bastion and them spread lies about him.

Meanwhile, Adrien was searching frantically for his Miraculous in the bathroom, but it wasn't anywhere and Plagg wasn't responding to his calls at all. He was really worried, but he couldn't ask around or anything, it would give his identity away. He did know that it wasn't that new guy, Bastion, he hadn't gone into the bathroom at all, and he'd been with Chloe, Kagami, and Marinette as well. He sighed, maybe Plagg was trying to find him, maybe he'd taken the ring and was trying to find him right now, but it shouldn't take so long then.

Bastion was in the locker room after school and no one was around, he'd just made a call and what he'd asked for would soon be here.

"Psst!" he heard, and he turned his head to see a floating black cat with green eyes, holding a ring, fly up to him. "Finally, you're alone, here, hold his for me," said the cat and dropped the ring into his hand.

"Parden me but who and what are you?" asked Bastion calmly, he was used to the unusual because of his family.

"I'm Plagg, I'm your Kwami, a Kwami is a divine being and basically a quantic or small god, that comes into existence each time a new concept is born, I represent the concept of destruction, the very first Kwami represents creation, that's when we really came into being. I can grant you superpowers Bastion, as long as you wear the ring and say the activation phrase," he said.

"I see. Why me?"

"Because one, Ladybug needs a cat, two, my old user was becoming unreliable and obsessive and not very useful in a fight. Three, you could say that he was a temporary holder until you came along, you have the soul of a cat, you're the real chosen one to fight alongside Ladybug and help defeat Shadow Moth," said Plagg.

"Your old user wouldn't have been Adrien Agreste, would he?" Plagg's jaw dropped in shock. "As I suspected, both have blonde hair, green eyes, same skin tone and are the same height. Counting the fact that this morning he had a ring on his finger and after he came out of the bathroom and he didn't and you're here now, I conclude he was that useless alley cat, Cat Noir," said Bastion and he slipped the ring on his own finger, it transformed from its natural state to a white ring with a cat's head on the top with blue eyes.

"That's the proof you're the true holder of the cat, only then will the ring transform!" exclaimed Plagg.

"Ok I'll do it, what's the activation and deactivation phrase, and is there anything else you need to tell me now?" asked Bastion

"You get five minutes after using your superpower, Cataclysm, before you power down. Your suit will be based on what you think represents a hero, I have other powers that are accessible through potions, Ladybug is the current Guardian of the Miraculous, Shadow Moth uses the Peacock and Butterfly Miraculous and you can fuse two or more Miraculous together. I also need food in order to recharge, I like camembert as my preference and I can't be seen in photos or video cameras, screens or by robots but unlike vampires, I do have a reflection. I think that's all the important stuff for now. You better get going or you'll miss your duel against that brat," said Plagg.

"Got it all memorized, one question, how will we hide that I'm now wearing two rings instead of one?" asked Bastion.

"Keep it in your pocket until tomorrow, then you can pass it off as a ring your family gave you, after all, it's very different from the form I gave you it in."

"Point," he said and popped the ring into an inside pocket in his jacket before leaving with Plagg hiding inside his pocket as well.

"Oh, Bastion, I thought you weren't going to how up," said Lila, looking terribly upset that he had, she had been prevented from sneaking away by everyone who wanted to see her duel.

"Just psyching myself up to win," he said. "Plus, you will call me Misawa sama as I am superior to you and you do not have my permission to call me by my first name, plebian," he said.

Lila went red with rage and her friends began to speak up for her, but Bastion turned his head to focus on the incoming limo that parked outside the school.

A man with black hair and sideburns, in a suit and glasses, stepped out of the driver's seat and walked up to Bastion with a package, "Bastion sama, the packages you requested," he said.

"Thank you very much Roland san," he said and tossed one of the packages to Lila. "It's a Duel Disk, unopened and as such, I can't be accused of cheating, since I'm also using one," he said, opening up the box and slipping the disk onto his wrist. Everyone was staring, Bastion had a limo! So that meant he was rich.

"How rich are you?" asked Alya in shock.

"I make the Agrestes look like paupers," is all he said as he put the new deck into the disk. "Ok, to be fair I'll explain everything to everyone before we start since it seems not everyone plays Duel Monsters," said Bastion, who quickly explained the rules and about the cards. "We'll start with four thousand life points each and the first to zero life pints loses. Let it be noted that both Rossi and I have brand new structure decks and they are also the same structure deck so no one can call out any cheating. The only thing I have on my side is experience," said Bastion.

B: 4000

L: 4000

"I'll start, I draw, now I'll summon Tune Warrior in attack mode, then I'll place two cards facedown and end my turn. It's your move," he said to Lila. (TW 1600/200)

"I play Man-Eater Bug in attack mode," said Lila. Bastion face-faulted, she was obviously not listening when he explained about Flip effect monsters. (M-E B 450/600)

"You do realize that Man-Eater Bug is a Flip Effect monster and far weaker than my Tune Warrior, right?"

"'It's ok, because I know that since we're friends, you'd never attack me and I'll play this card, Threatening Roar," she said but her duel disk beeps an alarm. "What's going on?"

"You can't use traps from your hand unless it's specified in the card text. You can only play traps facedown and then use them on your opponent's turn and afterwards," said Bastion, he was getting irritated.

"I'll play it facedown," she said and placed it on the monster slot, causing another beep. "Now what?"

"That's the monster zone, the spell and trap zones are the slots in the side of the disk, under the monster zones. Weren't you listening to a single thing I said earlier?!" he asked.

"I'll take another turn then," and she tried to draw a card, but her duel disk shut down. "What now!?"

"That's the third time you've made a mistake and didn't learn from it, it was my move, unless you have a rare spell or trap card that allows you to have a second turn right after your first turn then it's counted as cheating, the duel is over, I win," said Bastion and he took off the duel disk.

"Hold on, Lila, you're a dueling champion, how could you not know this stuff?" asked a confused Alya.

"I…uh…." She was cut off by a man getting out of the limo, along with a woman, four children and another man.

"That's because she's nothing but a liar," said the man who had brown hair, blue eyes and wore a white suit, "I am Seto Kaiba and that was a disgrace to dueling," he said.

"Hello father," said Bastion, and Seto nodded to him as he walked over and took the duel disk back and the deck as well.

"FATHER!" shouted the school, not just Bastion's class.

"Yes, Misawa is just a name I go by in order to try and live a normal life but in circumstances like this, well, the secret is out," said Bastion as he was handed a white trench coat by Roland and he shrugged off his yellow jacket, putting on the trench coat instead. Marinette, Chloe, and Kagami giggled; they'd known the whole time.

Lila couldn't believe it, this guy, Bastion, wasn't a nobody! He was the son of one of the most influential, richest, and famous men in the entire world. That meant that Bastion was, from his actions today, practically trained to spot liars and manipulators and he could get away with insults and such because of who he was as no one was going to risk bringing down the wrath of Seto Kaiba upon them.

"Hello Marinette," said Seto to the girl.

"Hello Kaiba sama," she said shyly, and Chloe and Kagami were also greeted. The three girls were hugged by the other man, whom Bastion introduced as his uncle Mokuba and the woman and four children were Bastion's mother, Serenity, and his siblings, Noah, who had his mother's hair and blue eyes, Usagi and Hikari had their father's brown hair and their mother's green eyes and little Timmy had blonde hair from his mother's side and purple eyes from his father's side. Bastion revealed that Rebecca Hawkins was married to his uncle Mokuba, and they had two kids and his other aunt and uncle were Mai and Joey Wheeler and they had triplets. They were all still in Japan and Mokuba was only here for a few days having wanted to ensure that the family was settled before going back to Japan and running the Japanese branch of Kaiba Corp from there.

Seto invited the three girls back to the mansion and they accepted. Bastion grinned and opened the door for the girls who got in as did the rest of his family. "So, dad, will we be adding Marinette, Chloe, and Kagami to the permanent visitors list?"

"Yes, only they will be allowed into the mansion on a permanent basis unless you make more friends that deserve it," said Seto.

"I think some new friends I made might find their way onto that list," said Bastion and they drove off, making everyone stare after them.

Alix and Nath felt relief that they'd realized their mistake and they went home leaving Lila to stew about how bad her day had been.
