Story will not be based around Percy. It will be based around my OC (Yes, it has a self-insert. Get over it). Story may stray from the original plot. Character is a Shinto Demigod, but also falls under the jurisdiction of Greece and has a chance for the great prophecy (will be explained at a later time). I'm not sure about the pairing just yet. PercyXAnnabeth definitely. Starts at the beginning of the Titan's curse.

Chapter 1: Middle School Dance

Reiji was wandering through the halls of Westover Hall, humming a tune as music played. He stopped in the entrance hall and leaned against a pillar, yawning lightly as he closed his eyes and listened to the music. He had always liked music, rock, dubstep, classical, anything. It always had a calming effect on him, even if it was an incredibly insane song. Of course he had songs he didn't like, but most music calmed him.

Reiji was always different from other kids at his boarding school. The first thing was his name: Reiji Sakazuki. He was born in an area near Japan, so his mother had given him a Japanese name. He never knew his father, which annoyed him to no end when people bullied him about it. It sure as hell didn't help that his mother had died 2 years before, when he was 12. Honestly the only people he connected with were the Di Angelo siblings: Bianca and Nico, who didn't know their parents either, and his friend Grover.

Another thing that made him different was that he could...sense a person's presence. He could tell what a person was kind of like or what they best related to just by being near them. For example Nico, even though he was always smiling, gave off the presence of death itself, but not in a bad way. It was a happy death, as if the person were finding peace. Meanwhile Bianca gave off a presence of darkness, but again, not in a bad way. It was a comforting darkness, like when you went to sleep and the darkness helped you.

The next thing were his looks. He has spiky black hair that covered his eyes and reached just below his shoulders. When people could see his eyes, they were a deep crimson that seemed to stare into the soul. Bianca and Nico didn't mind this. Nico thought it was pretty cool while Bianca said it made him unique. He was also paler than a normal person, not too much, but just enough to notice. His clothing consisted of a black pair of jeans, white sneakers, a black shirt and a black leather jacket with a hood. Around his neck was a necklace with a storm symbol. He also wore earrings, the one on his right ear with a moon symbol, and the one on his left ear with a sun symbol.

He had gotten his jewelry a few years before, when he was 10. He had just received a letter from his apparent father and his aunt and uncle. The only words written on it were: 'Be ready.' He didn't really get why he received the letter, but the jewelry was pretty cool, so he wore it. He also wore a silver ring on his index finger, another gift from his father.

That day his hair was tied back in a pony tail, his hair still spiky, just collected together. But while it was in a pony tail you could actually see his eyes. He usually tied his hair back at Bianca's request, because she preferred to talk to him when she could see his face properly.

He kept humming along with the music, enjoying the peace and quiet, when he heard the oak doors groan open. He heard a voice go, "Woah." He cracked open an eye and looked at who had just entered. It was a group of three teens: two girls and one boy.

The first girl he saw was, in his opinion, kind of cute. She had black, spiked up hair and electric blue eyes. She had freckles across her nose, but it just made her seem cuter in his mind. She wore punk style clothes: a black jacket, torn black jeans and a black T-shirt. On her wrist was a silver bracelet. Her presence was like raging thunder, ready to strike at any minute, easily prone to anger. However there was also a gentle breeze, which told him that she was also kind.

The other girl looked pretty, but wasn't Reiji's type. She had curly blonde hair that was tied back in a pony tail, and stormy grey eyes. She wore an orange T-shirt that read 'Camp Half-Blood', which raised one of Reiji's eyebrows. She also wore a pair of blue jeans and had what looked like a Yankee's cap stuffed in her back pocket. He could see something was hidden on one of her pockets, but payed it no mind. Her presence was like gears turning, which told Reiji that the girl was clever, but he also sensed their was one gear bigger than the others, doing most of the work, which told him that she was somewhat arrogant.

The boy was pretty cool looking in Reiji's mind. He had shaggy black hair and sea green eyes. He wore the same T-shirt as the blonde haired girl, but also wore a black jacket over it, along with blue jeans. He was definitely the one that had gone 'Woah' just a moment ago. His presence was like the sea, calm and gentle. But ready to crush any that deny the tides. This told him the boy was kind, nice to his friends, but ready to jump into battle if anyone messed with him.

Overall Reiji thought they would not act well together. He moved into the shadows nearby and watched, listening to what they said.

The blonde girl started to say, "I wonder where-"

The doors slammed behind them, and Reiji's eyes narrowed. That was not natural.

"Oo-kay," the black haired boy mumbled. "Guess we'll stay awhile."

The music shifted at the other end of the hall. It sounded a lot more like music you'd dance to now.

The three teens put their bags behind a pillar, as if hiding them, and started to walk down the hall. Reiji followed silently. The group didn't make it very far before Reiji heard footsteps on the stone floor, and a man and woman- Dr Thorn and Ms Gottschalk- marched out to intercept them.

They both had short gray hair and black military-style uniforms with red trim. Ms Gottschalk had a wispy mustache, and Dr Thorn was clean-shaven, which definitely should have been the other way around. They both walked stiffly, as if something were attached to them and keeping them standing straight.

"Well?" Ms Gottschalk demanded. "What are you doing here?"

"Um…" the black haired boy muttered. Reiji quickly understood they were not supposed to be here. Then he grew suspicious as to why they were here. The black haired boy kept speaking, "Ma'am, we were just-"

"Ha!" Dr Thorn snapped. "Visitors are not allowed at the dance! You shall be eee-jected!" Oh yes, Dr Thorn had a French accent, so his J sounded like he pronounced Jacques. Dr Thorn was really tall and menacing with his hawkish face. It did not help that his nostrils flared when he spoke and his eyes were mismatched: one brown, one blue.

Reiji was ready for Dr Thorn to chuck them out, but the black haired girl stepped forward and snapped her fingers. The sound was sharp and loud. Reiji shivered as he felt a gust of wind rip across the room. Suddenly he had the distinct impression the three had been students here for a long time...then he frowned. No that wasn't right. They had only arrived a few minutes ago.

"Oh, but we're not visitors, sir," the black haired girl said. "We go to school here. You remember: I'm Thalia. And this is Annabeth and Percy. We're in the eighth grade." Reiji's eyes narrowed. There was something off about these teens. And he didn't like it.

Dr Thorn narrowed his two-colored eyes. But something strange was happening. Dr Thorn seemed to be hesitating, as if trying to remember something like Reiji just had.

He looked to his colleague. "Ms Gottschalk, do you know these students?"

The woman blinked, like someone had just woken her up from a trance. "I… yes. I believe I do, sir." She frowned at them. "Annabeth. Thalia. Percy. What are you doing away from the gymnasium?"

Reiji glanced and saw Grover running over. He expected Grover knew them, so he made his move. He ran out. "Yo! Thalia! Percy! Annabeth!"

The three looked to him in surprise, as did Grover and the two teachers. He stopped in front of the three. "I told you three not to wander too far from the gym! You nearly got in trouble!" He sent the teacher's an apologetic look.

Thalia, Annabeth and Percy tried to hide their shock, with varying degrees of success. He turned back to the three. "Come on! Let's get back before Grover starts wondering where we disappeared to!"

Ms Gottschalk nodded, and Dr Thorn looked at Reiji with sympathy, as if he had just been caught under a spell. "Yes, run along." Ms Gottschalk said to them.

With a chorus of 'Yes, ma'ams' and 'Yes, sirs' along with a few salutes, the group walked away. Heading towards Grover.

Once they had gotten far enough, Reiji glanced at Grover. "G. Are these the friends of yours you told me so much about?"

"Ah, yes!" the boy said. "Percy, Thalia, Annabeth. This is my friend, Reiji Sukazuki. Reiji, these are Percy, Thalia and Annabeth."

Reiji nodded and looked at them. "You owe me."

Thalia's nostrils flared. "Excuse me? We had that under control!"

Reiji rolled his eyes. "Yeah, of course. Oh, and pigs fly, the sky is purple, space has oxygen and the Greek gods still exist." If he didn't turn he might have noticed them stiffen. They arrived at a door that had GYM written on the glass. "Now, if you'll excuse me, I'm gonna go hang out with Nico and Bianca." Reiji looked at Grover. "I want an explanation later G." Before he could receive an answer, he opened the door over to the siblings.

Nico and Bianca were standing in a corner, just talking. Reiji arrived. "Hey you two."

Nico smiled. "Big bro!" He tackled Reiji in a hug and he smiled.

"Hello Reiji," Bianca said with a smile.

Bianca was wearing a floppy green cap, like she was trying to hide her face. Nico was obviously her little brother. They both had dark silky hair and olive skin, and they used their hands a lot as they talked. Nico was shuffling his Mythomagic cards. Bianca seemed to be scolding him about something. She kept looking around like she sensed something was wrong.

"Why are you two just standing here? Why aren't you partying?" Reiji asked.

Bianca raised an eyebrow. "I could ask you the same."

"Touche."

Nico smiled. "Hey big bro! Can we play Mythomagic?"

"Eh sure," he sat at a table, and Nico sat opposite. "Oh! And here little man, I kinda missed your birthday last time, but I got you a present." Out his pocket he took out a figurine and handed it to him.

Nico's eyes widened. "Y-You got me Hades? But he's one of the rarest ones! How did you get him?"

"I went to a tournament over the summer and the reward was Hades." Reiji explained. "And I remembered you, so I decided to enter. Anyway, I managed to win and voila."

Nico smiled widely. "Thanks big bro!" He looked to his sister. "Isn't this great Bianca?"

Bianca smiled. "It sure is Nico," she looked to Reiji. "Thanks."

"Hey no prob, we're friends after all." Reiji said with a grin. "So, we gonna play?" Nico nodded and they set up the table. They played 3 games, and the results were fairly even. Reiji won the first game, with Nico winning the second. They ended up drawing on the third.

Just as they were about to begin the fourth game, Dr Thorn went up to them. "Excuse me," he said. "Are you having fun?"

"Yes sir," Nico said with a smile. Bianca nodded in agreement, though Reiji looked at him with caution. He had never really trusted Thorn.

"Good," the teacher said. "Could you two please come with me?"

"Why?" Nico said worried. "Did we do something wrong?"

"No, no, no," Dr Thorn promised. "I just need to speak with you and your sister. In private."

Nico nodded, collecting all his stuff and stood up. "Bye big bro."

"Goodbye Reiji," Bianca said politely.

"Yeah, bye," Reiji waved as the siblings left with Dr Thorn. As soon as they left, Reiji stood up. He looked across the floor and noticed that Annabeth and Percy were looking in his direction urgently. Reiji watched with suspicion. Why were they interested in him...no...not him...Bianca and Nico. The two disappeared into the crowd. Reiji quickly ran through the place Bianca and Nico had disappeared to. And his blood ran cold.

Bianca's cap was laying on the ground. Some of Nico's cards were on the floor, scattered (but thankfully protected with card sleeves). He looked around and saw Dr Thorn leading the two away by the scruffs of their necks. He glanced over and saw Percy was looking at him as well. Then he looked at where Thorn had disappeared to with his friends. Reiji growled. He quickly picked up Bianca's cap and Nico's cards, and hurried after Thorn. Percy seemed to hesitate when he ran off, but he quickly followed.

The door led into a dark hallway. Reiji heard sounds of scuffling up ahead, then a painful grunt. Reiji, subconsciously, clutched his necklace, as if it would somehow help in. He heard the sound of a pen lid being taken off and glanced back. His eyes widened. Percy was standing there, a bronze sword that seemed to glow pointed at Reiji's back.

"Don't move," Percy warned. "Why are you following Thorn and the siblings?"

Reiji turned with surprising force, which made Percy jump. "Why wouldn't I run after my friends when some Psycho is hurting them?" He said in a harsh whisper before he turned away and hurried down the hall. He heard footsteps behind, indicating Percy was following him.

The twp jogged down the corridor, but when they got to the other end, no one was there. Reiji opened a door and found himself back in the main entry hall. Reiji's blood ran cold. He saw both Bianca and Nico standing on the other end of the hall looking at him and Percy in horror. Where was Thorn?

Percy didn't seem as worried as Reiji was. He advanced slowly, lowering the tip of his sword. "It's okay. I'm not going to hurt you."

They didn't answer. Their eyes were full of fear. Reiji's mind was moving at a hundred miles an hour. Nico and Bianca weren't afraid of him. And they certainly weren't afraid of the sword in Percy's hand. They were looking somewhere else...behind them.

"My name's Percy," the black haired boy said, trying to keep his voice level. "I'm going to take you out of here, get you somewhere safe."

Bianca's eyes widened and her fists clench. As if following his instincts, Reiji ducked as Percy turned. Something went WHIIISH! Percy yelled in pain. A huge hand yanked him and slammed him against a wall.

He slashed with his sword, but all he hit was air.

A cold laugh echoed through the hall, Reiji shivered.

"Yes, Perseus Jackson." Thorn's voice echoed, his accent causing him to say Jackson in a slightly different way. "I know who you are."

Percy tried to free my shoulder. His coat and shirt were pinned to the wall by some kind of spike—a black dagger-like projectile about a foot long. It had grazed the skin of his shoulder as it passed through his clothes. There was a mild green liquid and Reiji quickly understood exactly what the problem was. Poison. Percy had been hit by poison.

Percy's face was struggling with concentration, as if staying conscious were incredibly difficult.

A dark silhouette moved forwards, Dr Thorn stepping into the dim light. He still looked human, but his face was ghoulish. He had perfect white teeth and his brown/blue eyes reflected the light of Percy's sword.

Reiji wanted to scream, but he didn't trust his voice.

"Thank you for coming out the gym," Thorn said. "I hate middle school dances."

Percy tried to swing his sword again, but Thorn was just out of it's reach.

Reiji's eyes widened and he moved out the way. A second projectile shot from behind Thorn, as if something invisible were standing behind him throwing knives. Reiji had just barely avoided it. Bianca screamed.

He turned and ran to his friend. The second thorn had impaled itself in the stone wall, half an inch from her face.

"All of you will come with me," Dr Thorn said. "Quietly. Obediently. If you make a single noise, if you call out for help or try to fight, I will show you just how accurately I can throw."

Reiji spoke just quietly enough for Thorn not to hear. "Mother and father in heaven...please watch over me...I am about to do something stupid again..."
