Author's Note: For everyone reading this story, I just wanted you to know that this is supposed to be the official sequel to "Mayhem Squared" another story by me (of course). But if you really don't want to read that 20 chapter long story, you can just read this one directly. You'll still get it, although I would have to say you are missing out on another adventure of the Lyoko gang if you don't read my other story (if you do, it would be much appreicated if you drop a review!). But if you don't want to, I'm totally okay with it and I hope with all my heart that you'll like this story! Okay, on with the first chapter...

"School's out for summer!" Odd screeched in a bad version of what he believed to be called "singing".

"Okay, Odd," I said, thoroughly annoyed. "Number one: school is out for break, not for summer. And number two: would you please stop trying to shatter the school's windows?" I glared at him as he grinned in return.

"Sorry Yumi, but I knew some great singing would cheer you up," he said, all smiles as he walked with me to the cafeteria.

"Oh yes, Odd. Great singing. It just made my day." I laced my words with sarcasm. Odd, used to this already, just smiled wider.

"Well, if my fantastic singing hasn't made your day just yet, something else will," he said, pointing ahead of him. "Your Ulrich-poo!" I socked him on the arm. "Ouch!" he muttered. "Remind me never to try and make you happy again." I laughed at that.

"Hey guys, what's up?" Ulrich asked as we walked up to him and Jeremy.

"Oh nothing. Just Odd trying to be the stand up comedian he isn't while trying to make my day." Odd scowled at me. Ulrich and Jeremy laughed.

"I see," Ulrich commented. "Must have been interesting."

"Very," I assured him. "What's up with you guys? And how's Aelita? I haven't talked to her for a while since Xana's army was destroyed."

"She's fine," Jeremy said quickly, his eyes twinkling. "She said that after we demolished Xana's grand attempt at trying to destroy us and conquer the world that he kind of lost heart and has given up."

I snorted. "Isn't that a bit too extreme a conclusion? Xana's probably as mad as a hornet, not like he isn't one already."

"And he's probably out for some revenge," Ulrich finished for me.

Odd cringed. "I wouldn't want to stick around when he tries that!"

I rolled my eyes. "Odd, if he does try to take revenge on us you'll have to stick around. You'll be helping us stop him!"

Odd thought for a moment. "Oh yeah. I guess not being in Lyoko for so long has made me think I'm actually a normal kid for a change."

Ulrich shook his head. "For you Odd, its impossible to be normal."

"Speak for yourself," Odd countered and stuck his tongue out at Ulrich.

"Oh look! It's the freaks," said a snide voice from behind me. I turned to see Sissy. She was followed not by Herb and Nicholas this time, but by two of her just as snobby girl friends who had joined her posse recently. She must have liked them the most to bestow the privilege of letting them follow her around. If she had asked me to follow her around or even begged me to join her posse, I would have died instead.

"Oh look!" Odd mimicked, "It's the idiots!" Sissy narrowed her eyes hatefully, but her eyes softened when she gazed at Ulrich. I noticed this and clenched my fists.

"I have no time for your stupid insults today. I have actually come for Yumi." She folded her arms across her chest triumphantly and glanced at me with smugness I didn't like. I started.

"For me?" I asked, puzzled. Then I made my face look resolute. "For what?"

"My father, also known as the principal of this school, would like to have a word with you." Now Sissy's minions got infected with the smug look. I gazed at them critically, and then decided that the biggest threat was still from Sissy, not from them. Suddenly, Ulrich grabbed my arm and pulled me closer to him.

"She doesn't seem to be telling the truth," he said in a whisper that I could barely hear. I watched as Sissy's face turned into a look of annoyance. She was clearly being bugged that Ulrich was talking to me privately. Sucker, I couldn't help thinking. Ulrich, meanwhile, continued. "I think it might be a trap to do something to you."

I pulled away from him a bit, surprised. "You're talking as if Sissy is Xana!"

"She is just as bad," he said. I gave him a skeptical look, one eyebrow raised. Sighing, he relented. "Okay, Xana's much worse but she was infected by Xana once. What makes you think that he isn't at it again?"

"Well," Sissy said impatiently, all smugness forgotten. "Are you coming or not? My dad will be very displeased if you don't go to talk to him."

I looked back at Ulrich. "What if she's actually telling the truth this time? And besides, if she does spring something on me, I'll just kill her. It'll take her off our hands," I joked. Ulrich still looked unsure but I winked at him. Then I pulled my arm out of his grip and walked over to face Sissy. "Okay, I'm coming with you. Let's go."

Sissy smiled eagerly, the smugness returning. "Follow me," she said as she started walking.

I rolled my eyes. "Sissy, I know where the principal's office is. You don't have to escort me there."

"Oh yes I do."

I sighed irritably. "And why is that? Afraid I'll run and hide in the sewers?" I rethought what I had just said and cringed inwardly. Nice going, I thought to myself. Did you have to use an example so closely tied to the warehouse and Lyoko?

Sissy brushed it off though. "No, but it suits you if you were to do that." I glared at her as she turned around. "I'm not escorting you to the principal's office."

"Good, so can I go now?" I asked hopefully. She laughed evilly.

"As if! You're not going to the principal's office at all." She snapped her fingers and I realized too late that I had been walking between her and her minions that were trailing us. Now they lunged at me from behind and grabbed my hands and arms tightly, digging into the ground to hold me fast. I realized then, also, that Sissy had not picked these two girls because they were her favorites but because they were the strongest she could find. And now that we were far enough from the boys for them to not see or hear, I was thoroughly trapped. She laughed again. "Aw, poor helpless little Yumi. With no prince charming Ulrich to save her." She thought over her statement then quickly corrected herself, "As if he was your prince charming anyway. Everyone knows he's mine."

I sighed and struggled to break free from her cronies' bone breaking grip. "Whatever Sissy! Just would you mind explaining to me what you're going to do to me?"

"Oh," she said, remembering her grand scheme. "Right. Well, anyway, you're not going to go to the principal's office. Not at all." I sighed heavily. We've already been through this, I thought in boredom. She continued. "You are going straight to my room!"

"And what exactly are we going to do there? Have a tea party with your porcelain dolls?"

"No," she snapped harshly. Then a slow smile crept across her face. "I'm going to see what Ulrich really likes in a girl."

"Okay," I said, "you've lost me."

"Well, Yumi, it seems I have to spell it out for you. I'm going to give you a life altering change that will test Ulrich to his limits. I'm going to surprise one and all with what I'm going to do!" I yawned in disinterest. "I," she said very softly, and she leaned in to make sure I heard, "am going to remake your looks into an exact replica of the beautiful yours truly. Me!" She flung her arms out wide as if she had just finished performing the grand finale dance scene in a musical.

"In other words," she said quickly, her smile of smugness returning once again, "I'm going to give you a makeover."
