EDIT: Updated the story pic so it's not so ugly! Drawn by yours truly ;D

(A/N: Okay, so there are a LOT of Percy's twin sister stories out there, no? So, I decided to take my own...um...take...yeah...

I'm not sure if you could call this parodic or not. I guess it's the middle ground? The characters are SUPPOSED to be in character, except for Percy a few times, because he's an idiot in this. Yes, he is an idiot, but in this, he's more of one than usual. Otherwise, if you find any of the characters OOC, it will be because of the lack of skill I have. I know, I'm not good at humor or romance. -_- The "funny" parts are just there to make the story more "colorful". (And to imitate Mr. Riordan's style more). Please point out anything I should improve on! :D

Rick Riordan obviously owns the series and characters. (Except the "mysterious girl". Yeah, I won't put that burden on him.))

Before we start, I swear on the river Styx that I usually don't attack old ladies.

Anyways, everything was going great until the week before we would be released for Holiday Break. There were no signs of anything to do with Greek mythology as I strolled through the gold and purple themed hallways that were illuminated by the florescent lights (which I really hate). Of course, it could've been the Mist just tricking me, but I decided to let myself enjoy the bliss of actually having a normal high school experience.

Today we got our new classes for the second semester. It was kinda weird that we went into the next semester right before we went off for Holiday Break. Not to mention that we did this on a Tuesday, not a Monday. But hey, whatever works. As soon as I stepped into my new physics class, my grins and dreams vanished. Chills overcame me, and my stomach dropped. I felt like I was going to puke all over the grayish purple carpet. Something definitely was off.

"Perseus Jackson!" my teacher snapped in a shrill voice. "You are tardy! On the first day of this class! How careless! You should be ashamed of yourself!" She punctuated every syllable of the last sentence.

"I...erm...uhhh...," I stammered. I didn't even think I heard the bell ring yet.

I nervously scratched the back of my neck, which was coated in cold sweat, and looked up at my teacher. She was an old, lanky woman who wore a shade of a deep reddish eggplant lipstick and a little too much eyeshadow in a matching color. Her hair was a dull brown and pulled into a tight bun.

The sound of the bell echoed though the silent hallways.

"What are you doing, just standing there? Do you want to be even more late, Perseus Jackson?" she croaked.

"But, I was already in the classroom when the bell rang!" I protested.

"It does not matter!" she snapped, "You were not in your seat yet! And you are still not!"

In a way, she reminded me of my former algebra teacher, Mrs. Dodds, who turned out to be one of the Furies. That didn't necessarily mean that she was one of them. So instead of judging her as one and running off, which would probably get me into trouble, I glanced at my classmates. All of them were staring at me, and most were either outright hysterical or giggling. With burning cheeks, I took my seat in between two girls, which was unfortunately right in the front. The teacher started lecturing about classroom etiquette or whatever. It was basically common sense and unimportant, so I lost interest and started playing thumb wars with myself.

SLAM! I jumped and looked up. My eyes were staring into the furious ice blue eyes of the teacher. I swore I saw the veins pulsate in her eyes. Some were also twitching on her neck. The florescent lights, which started to give me a throbbing headache on my temples, made her wrinkles and bags have her look even older. Did I mention I hate those lights? Well, I do.

"Perseus Jackson! Pay attention!" she screeched with pure fury. She was holding a meter stick, so she probably used that against my desk. However, with her anger and pose, it looked like she was going use that as a weapon against me instead.

Once again, most of my classmates laughed. My cheeks weren't just burning anymore, my whole body was. Right then, I wished I could disintegrate into golden dust like a defeated monster, or at least shape shift into a bird and fly out the window. But being a child of Poseidon, all I really wanted to do right then was to plunge into the nearest body of water and sit on the bottom all alone.

Anyways, after staring me down for few, she went back to lecturing us. I pretended to listen by looking at the blackboard. The combination of her shrill voice and the strain on my eye trying to make out the faint chalk on the blackboard-especially with dyslexia-made my headache even worse. You might be wondering why someone with the Curse of Achilles could experience a headache, because it's pain, right? The curse only protects you from external pain, unfortunately. Anyways, I made out the teacher's name on the blackboard. It was Ms. Aima, which means blood in Greek. Great.

I heard giggles coming from either side of me. They were still laughing at me? I gave a death glare to the girl to my left, who had curly caramel hair, tan skin, and brown eyes. She gave me a pearly, flirty smile and wave to me, which I didn't give back. Awkward. I jerked my head to my right to look as far away from her as possible. The moment I layed eyes on the other girl, I felt nauseous and a chill ran up from the core of my spine. She was also giggling at me, but in more of a mocking way. She had long, jet black hair and sea-green eyes. There was something different, yet familiar about her. I didn't recognize either of them though, which wasn't surprising. Goode is a pretty big school.

In the middle of Ms. Aima's tirade, the girl with the black hair raised her hand.

"What is it, Pearlcilina?" Ms. Aima asked.

"May I use the bathroom?" responded Pearlcilina.

"Yes, but be back in five minutes! If you are not back then, I will give you detention."

I had an anxious feeling, as if Pearlcilina was in trouble. I didn't know why, but I had a strong urge to protect her, even if I just learned her name.

"Ms. Aima?" I asked about seven seconds after Pearlcilina walked out.

"What?" she croaked. "Do not interrupt me in the middle of the lecture I am giving you! And you must raise your hand before you talk to me!"

So I raised my hand.

"What?"

"I have to go to the bathroom really bad."

"No! Only one person goes at a time! Besides, I am lecturing you!"

"But I have to go really bad. If I don't go to the bathroom, I'll go on one of your chairs!" I desperately protested, ignoring the laughs.

"Perseus Jackson! You are not going to the bathroom right now, and if you go on one of the chairs, I will send you home!"

I kinda figured that she wouldn't let me go anyways, with the possibility of being one of the Furies. So I did what any crazy person would do. I bolted out the doors.

"Pearlcilina!" I shouted when I saw her figure near the end of the hallway. I sprinted as fast I could up to her, while she looked at me like I was a freak.

"What the heck? What's wrong with you?" Pearlcilina irritatedly questioned.

"Uh..."

I had no idea what to tell her. Ironically, it was Ms. Aima who saved me from looking like a complete idiot. Or maybe not.

"PERSEUS JACKSON!" Ms. Aima hollered in her all-becoming familiar voice as she quickly marched down the hall.

I turned around to face Pearlcilina and said, "Don't worry. I got this." Her arms were crossed, and her face remained skeptical. I wasn't sure if she was amused, annoyed, or both.

Ms. Aima was almost to us. When she crossed the drinking fountain closest to us, I felt a familiar tug in my gut and let all the water out. She then slipped and fell on the ground. As I maneuvered my way towards her and then uncapped Riptide, she was sopping wet and shrieking like crazy. When I was close enough to her to see her features, I saw that her reddish eggplant lipstick and eyeshadow were running down her face and that some her hair was plastered to it. Her vessels in her neck, eyes, and a bunch of other places were pulsating more than ever, and her face was scarlet with rage. She sure looked like a monster, but she wasn't. At least not yet, anyways. I didn't wait for her to make her transformation. I took advantage of this and rashly slashed Riptide at her. Instead of disintegrating into golden dust, Riptide went through her.

I reasoned it was because she was still in her human form, until she exclaimed, "Do not dare to use your pen on me as a weapon!" And then it hit me. Ms. Aima was mortal after all! I guess some teachers are just naturally sadistic. Well, this was sorta awkward.

"Oh...um...sorry...I thought you were a monster or something," I muttered as I gingerly offered a hand to help her up, but Ms. Aima only gave me a well-deserved death glare.

I turned around, as I was alarmed from some cackling laughter that came from behind me. The laughing belonged to Pearlcilina, whom must have snuck behind me while all of this was happening.

"A pen? I'm pretty sure that's a sword he has there," Pearlcilina told her. She then bore her sea-green eyes into mine. "How did you turn your pen into a sword, anyways? It this some stupid metaphor involving pens being mightier than the sword or something?"

After her annoying, sarcastic remark, I heard more laughing coming from behind me. It obviously wasn't from Pearlcilina, and it was too juvenile to come from Ms. Aima. I turned around once again and faced the owner of the mocking laugh.

"What's up?" the girl with caramel hair who was hitting on me earlier asked. She flipped her hair and waved her sickly green bony hands with sharp, perfectly manicured claws. Then she gave me yet another flirty smile, which was full of rows porcelain razor-sharp teeth. How attractive.

Ms. Aima must have seen the girl's monster form at least partially, because she screamed in terror and cowered into a ball.

"Now's really not the time to flirt," I snarled.

She slowly approached me with legs that now appeared as python tail trunks, which meant that she was a Scythian Dracaenae.

"You think I still want to flirt with you after you mistaken the monster for a mortal teacher? Why is it always the teacher? Your mind is so clichéd and minuscule. Even after defeating the Titan army, you still wouldn't know a Dracaenae if she sat by you, which I did! l won't take pride in eating you anymore just for that, Perseus Jackson. I will tear you in shreds instead to end your pitiful existence. Then, I will snack on you anyways, because I'm hungry!"

"Lovely," was my witty response.

"You're an idiot," the monster growled.

One by one the sprinklers went off, quickly followed by the shrill ring of the fire alarm. Don't look at me- I didn't cause it! It obviously wasn't my mortal teacher or the Scythian Dracaenae, either. I shot a glance at Pearlcilina.

"What?" Pearlcilina indignantly asked.

Luckily, there were no extra witnesses from the students rushing out, since we were in an isolated section of the hall. I sighed with relief as the cool, relieving drops made my headache flow out of my temples and my body surge with energy. With these advantages, I took the initiative.

I charged and feigned a slash at the monster's abdomen, knowing that she would strike back in that direction. Then, I dived into a crouch and struck her serpent trunks with Riptide. Obviously not too excited about this, she smacked Riptide out of my hand and violently clutched my upper arm with her razor claws.

Her cold eyes gave me a paralyzing stare, but I snapped back into reality when I hatched a plan, remembering that Riptide always appears back in my pocket. Feeling the familiar tug once again, I made the water burst from the drinking fountain even more and go in our direction. Hopefully Ms. Aima panicked away from the drinking fountain. The immense pressure of the water slammed the Scythian Dracaenae and me against the lockers. Overwhelmed by the force, she lost her grip on my arm. With some struggle, I slipped my hand into my pocket and retrieved Riptide. Then, I swung at her abdomen for real this time, and she quickly disintegrated into dust.

Just when I thought I would catch a break, the windows shattered into a million pieces and made a loud crash.

"P-Percy!" Grover desperately bellowed while crashing through the windows on Blackjack.

"Grover? What, um, are you exactly doing here?" I asked, very confused, while struggling to not groan. Usually, I don't like it when people other than me ride Blackjack, but I guess it was okay this time. Grover was my best friend, and this was kinda an emergency.

"I sensed danger coming for you! You know, the empathy link?"

"Ahem? Hello?" Pearlcilina chimed in. "A weird guy with merman powers I saw on TV attacks our teacher and a snake lady, there's a random fire alarm, and a goat boy crashes in while riding a unicorn. Yet, nobody explains what the heck is going on!"

"Actually," I intellectually responded, "it's what the Hades is going on."

"I'm a satyr!" Grover cried. "And Blackjack is a pegasus!"

"Huh?" she asked.

"No time to explain," I solemnly said. "Just get on the pegasus!"

After Pearlcilina found a spot on Blackjack, I went up to him and petted him.

Hey Boss!

"Hey, what's up, man?" I smiled. "Thanks for coming to the rescue."

Watch out!

Huh? He started to kick his legs in the air and freak out. I glanced up to Grover and Pearlcilina for reassurance for whatever the Hades was going on. That didn't work, though, because they were staring at me, horror-stricken. Wow, thanks guys.

"What?" I anxiously exclaimed.

I thrust my hands out to put more emphasis on my confusion, and I realized I hit something with Riptide. I guess I forgot to recap it. When I turned my head to inspect what the Hades I hit, I discovered that I just accidentally severed the head of the Scythian Dracaenae, who was right behind me. Hey, didn't I just kill her? Monsters reform, but not that quickly.

Before the monster could reform again, I slid on Blackjack.


While we were riding on Blackjack, Pearlcilina randomly brandished out a deck of cards. "Anybody want to play?" she inquired.

"Right now? We're kind of riding...on a pegasus...," Grover expressed.

"Whatever."

Hey Boss, can I just kick that bratty girl off my back? She's really annoying.

I widened my eyes. "No!" I loudly insisted. "That's terrible!"

But, Boss, how do we know that she's a half-blood? What if she's just a random mortal?

"We don't know, but if that's the case, we can manipulate the Mist," I reassured.

"Why is the merman dude talking to a horse?" Pearlcilina flatly asked.

Are you sure you don't want to-

"Yes, I'm sure," I interrupted before I could change my mind.

The rest of the way to Camp Half-Blood, Grover explained Camp Half-Blood and all that. Poor guy, it looked like she was going to beat him up the whole time.
