I'm not too sure what kind of relationships to include in the story yet. Obviously, Percabeth is here, and Thalia won't be in any kind of ship since I don't plan on having her break her oath as a hunter. I'll take suggestions for ships, interactions, and friendships that could happen during the story! I'm open to quite a lot of ship ideas, so go ahead!

I don't think Clarisse's age was ever mentioned, but I assume that she was fourteen in the first book, which would mean that she's two years older than Percy and eighteen in this fanfic. Nico is twelve, Annabeth and Percy are sixteen, Thalia is almost eighteen, but she looks sixteen, and Luke is twenty-one.

I always love reading reviews, and I read every single one, so thanks to the people that have been reviewing! It means the world to me.

Chapter 3 - Nico

Nico stayed silent as the older demigods spoke in hushed voices, Annabeth leading along on the plan they were currently making. The heroes; Midnight and All Might, had left to speak with some higher-up called Nedzu or something.

"I think we should prepare for some kind of test when we're all better. Nico, Clarisse, and Percy, you're all gonna be off the IV soon, so try to hit the hospital's gym as soon as we have permission to do so. I don't want to try sneaking out only to get in deeper trouble in a completely unknown space, so that's the best excuse we'd have to explore this place a bit," Annabeth said, crossing her hands over one another on her lap.

"Yeah, it's a good idea. Besides, my muscles have been aching for a good workout lately, and it'd be fun to have a little match with bathroom boy over there," Clarisse said while looking pointedly in Percy's direction with an animalistic glint in her eyes. Percy tensed a bit and laughed nervously.

"Sure, okay, no weapons though. We could have an endurance competition on the treadmills and stationary bikes though," He suggested, with Annabeth smiling proudly beside Clarisse on the daughter of Ares' bed.

They had learned the hard way that their bracelets weren't stopping them from getting off their beds, just from leaving the room.

The hard way being when Percy fell off his bed when he was sleeping, and they all woke up thinking for a horrible second that he had gotten shocked so hard by it that he blacked out.

Thankfully he woke up when Nico turned the light on, sending relieved sighs through all the demigods when he stood up, completely unhurt. They should have all thought about it, considering they would have to leave their beds to enter the bathroom whose door was just beside the empty bed within their room.

On their last day attached to the IVs, Nico got sick of waiting for Annabeth to bring up the incredibly important information topic, so he did it himself.

"What are we gonna do when those heroes come back? Tell them the truth? Or keep lying until they find out that we're liars? Cause I doubt they had that conversation with us only to leave and not come back."

They all stared at Nico for a moment before the first audible noise was Annabeth's deep sigh.

"We can't tell them what we are. The mist will just cover it up anyway, so it's seriously no use. Besides, they already believe that our demigod powers are just quirks, so it's easy to keep on going like this. What I'm most worried about are our origins. How do we explain certain things? Our scars, for example, as well as some of our traditions could make some questions arise. I doubt that people around here burn half of their food, and I don't think we can just pretend that it's an American custom," She said while rubbing her temple with her right hand, grey eyes disappearing behind her now closed eyelids.

"We could say it's our religion? That's basically what it is anyway, so we wouldn't really be lying," Thalia said, looking up from the magazine in her hands.

Nico did a double-take as he saw the magazine, then looked at Thalia.

"Wait..! When did you get a magazine? Isn't that the perfect way to collect information about this place?" He said before looking around the room for any kinds of books. There weren't any, unfortunately.

"I asked a nurse for it last night – you were all asleep, but I woke up in the middle of the night and wasn't able to fall back to sleep. You could just ask the next nurse that comes in for some books or newspapers," She said nonchalantly, shrugging before she then returned to her magazine.

At that moment, it was safe to say that everyone else in the room was surprised and suddenly much more hopeful, with that simple but incredibly helpful information. It wasn't suspicious to ask for a newspaper, which meant that they could easily learn much more without making shaky hypotheses.

It was only a week later that the heroes returned to them, two weeks after their first meeting. This time, four people walked inside the room. The first two were the same as last time – Midnight and All Might. The two others were strange – one of them was a black-haired man covered in bandages, and the other looked like a humanoid mouse. They were respectively introduced as Eraserhead and Nedzu.

Eraserhead looked incredibly annoyed, probably having been brought to the hospital against his will. Though Nedzu seemed ecstatic, from what Nico could tell based on an animal's facial expressions.

They all stood in silence, Percy having just left the bathroom and froze mid-step when he noticed the newcomers, while Clarisse had been in the middle of performing a dare from Thalia ('I bet you can't stand on one leg for a whole hour').

The awkward, uncomfortably suffocating silence was interrupted by Nedzu, who perked up and ended up sitting on an incredibly reluctant Thalia's bed.

"Hello! You may be wondering why I happen to be here, today when you don't even know me. I may not be a pro hero, but you're lucky to come face to face with someone better than a hero!" He paused for a moment. Dramatic flair, maybe? "That's right, I'm the principal!"

"…That's it? What; is your punishment for us just to send us back to school? That's kind of lame, man," Percy said as he walked over and sat down on his bed, crossing his legs while he stared down at Nedzu.

The heroes gave each other some nervous, knowing glances before looking down at the principal, whose expression hadn't changed from its previous relaxed one.

"Something like that, yes. We can't have some possible villains running around Japan when we could've easily taken care of them, but at the same time, we can't actually arrest you, since you haven't actually done anything particularly villainous in any camera footage or witness reports, aside from trespassing. Because of this, our next best option is to keep a close eye on you. The best way to do this without accidentally spreading this information across civilians and other heroes is to have you go to my hero school, where you'll be watched almost 24/7."

Clarisse let out a low, surprised grunt at the new information, nearly setting her foot down on the floor before she regained her balance, "What, so we're just students now? I skipped high school for a reason..! And besides, we're all different ages; you can't seriously place us in the same school when we're so far apart in age. Or, well, me and Nico are far apart."

Nico huffed, crossing his arms tighter across his chest as he stared at the adults. Smiley was clearly bothered by something if the sheen of sweat on his forehead meant anything. The lady was quiet with a small smirk on her face, and Bandages was obviously excited to leave.

"Now, you will be staying here for only today and tonight and will be escorted to the school tomorrow morning. You will be spending the day with our first-year classes, so be prepared. As for where you will be living, you will be sent to stay at certain pro heroes' homes. You'll find out who tomorrow," With that, Nedzu got off of Thalia's bed, dusted off his pants, and exited the room, followed by the heroes.

They seemed to be excited to get out as if the teenagers would attempt to jump three grown adults and a sociopathic mouse. Nico snickered to himself as he watched them leave and close the door behind them

"So, I guess we should prepare for what will happen. It seems we'll be separated, at night at least. We should be prepared for what that entails," Annabeth said, already getting down to business. She only had a simple strip of stretchy black fabric over her left arm, where she had been poisoned. None of them were on the IV anymore, and Thalia was due to get her braces removed in about a week – they hadn't been able to use ambrosia since all of their things had been taken away before being brought into the hospital room.

"Considering the current situation, we could ask for phones. I mean, we might end up attracting monsters, but it's better to keep in contact when we can't," Thalia said, her eyes not breaking away from Clarisse's leg, which was still not touching the floor.

Annabeth nodded slowly and crossed her arms, "That's understandable. I already have my own cellphone, but our things were taken away when we were first brought here, so we'll have to wait until tomorrow. You all already have my number, so try to call me if you get access to a phone."

All the demigods nodded at the same time, eyes burning with determination.

The rest of that day was spent with them planning for whatever situations could be thrown at them, and the evening was calm and silent. Clarisse and Percy had gone off to the gym, while Nico decided that he'd wander around the small shop and dining area a bit further down from his room. He knew he was being followed by one of the guards that had previously been in front of their hospital room, but Nico paid no mind to it as he stared helplessly at the menus – all written in Japanese.

Okay, so it looks like we can understand Japanese when spoken, but not when we read it. That's kind of obnoxious – how are we going to explain that?

He grabbed a bag of chips and bought it with the small amount of money they were given to splurge on whatever they wanted, as long as it wasn't a weapon. Nico then left the store and walked back to their room, dumping the chip bag onto his bed.

"We can't understand the writing," He said simply before opening his bag and starting to snack on what he bought. Annabeth had perked up from the book she had been reading, before sighing and looking back down at it.

"We can say we only took the time to learn the spoken language and not their alphabet. We're clearly foreigners, so it probably wouldn't be hard to believe. Speaking of foreigners, we should say that we're Greek. I don't want them to give us things in English, only for our dyslexia to get in the way," Annabeth said calmly, not looking up from her book as she spoke. Her quick thinking skills were thankfully very helpful.

The rest of the night passed without any disturbances, thankfully. The only event that happened was the removal of Thalia's leg braces, where she had immediately jumped up to her feet, clearly glad to finally be able to move around.

The next day, they were all woken up at around 6 am by none other than Eraserhead, who was still completely mummified by his bandages. He had arrived with, not only their things but uniforms and book bags, all filled with school supplies.

Nico was used to school uniforms, thanks to the Westoverhall, but it was funny to watch the other demigods (namely Percy and Clarisse) struggle with their ties. Annabeth ended up helping them out, and soon the five teenagers were dressed, with their weapons and magical items all stashed in their bags with their gym uniforms and books – save for a few exceptions, like Riptide and Nico's skull ring.

They were all ushered into a black SUV, with Eraserhead at the wheel. He spoke in a monotone voice, telling them his name and talking about school rules or something of the sort. Nico wasn't sure since he was quick to drown out the sound of the teacher's talking with his own thoughts.

It took about two hours for them to finally arrive at the school, a huge building with large windows all along the walls, and a big gate in front of the entrance. It was, in one word, extravagant.

And the demigods certainly were not ready for that.

"Woah, it's huge..! And clean!"

"Is there a pool? I can tell there's at least one pool."

"Damn, I can't wait to get in there"

"Percy..! Look at the architecture on that thing! It's so beautiful!"

"Annabeth, are you crying?"

"What? N-no… You didn't see that!"

As Annabeth wiped the obvious tears from her face, the car came to a halt in front of the school's entrance.

Eraserhead turned to look at the new students and passed them each a card.

"Those are your temporary student IDs. Don't lose them, if you try to walk in the school without them, the security system will go off. You'll get the permanent ones when your pictures are taken."

They all grabbed one and left the car one by one when the hero disembarked. The driver left them, and Eraserhead walked towards the building without turning to check if they were following.

Annabeth was the first to react, jogging towards Eraserhead and the school, a huge smile appearing on her face as they approached, allowing her to inspect the architecture from much closer.

Over the course of the hour they were given to explore the school and have their pictures taken for their official student identification cards, more and more students were seen entering the grounds and walking through the halls.

The first time they'd seen a mutated student, all of them had gone to pull out their weapons – Annabeth and Clarisse being the exception since they'd both lost their own weapons in the war. They had been prepared to kill the stranger until Annabeth pointed out that the person was wearing a school uniform, and was clearly not interested at all in the demigods.

That second point was enough to prove that it wasn't a monster, considering the combined smell of the three children of the big three would have been irresistible.

Soon, Eraserhead led them towards a classroom, a huge door with the code '1-C' on the front, and opened the door.

"Chase, this will be your classroom. As your quirk isn't actually fit for combat, we can't let you enter the hero course. The general course will be good enough. Your teacher is Snipe, you can greet him yourself," He said in his usual monotone voice, and then continued on without saying another word to Annabeth. The blonde stared at them as they left before she walked into the class.

Next, they arrived in front of a door with '1-B' written on it. Eraserhead opened up the door and walked inside, quietly greeting the teacher with a nod of his head.

"Di Angelo, Larue, this will be your class, and your teacher, Sekijiro Kan, or Vlad King. Introduce yourselves to your classmates, I have my own class to get to," Eraserhead once again left them alone, and Nico had to watch as he walked away with Percy and Thalia.

They entered the class and came face to face with the tall and muscular teacher – Sekijiro. He looked somewhat normal if you ignored the tusks sticking out from his mouth and his spiky white hair.

"Welcome, please introduce yourselves to the class," Sekijiro said in a deep, gruff voice, but with a kind smile on his face. Nico went first, looking at his future classmates as he spoke softly.

"My name is Nico Di Angelo, but please call me Nico. My friends and I are all here from Greece," He said, then glanced over at Clarisse.

He knew it was very obvious that they were both not the correct ages to join the class, and some students were very noticeably confused.

"Yo, I'm Clarisse Larue. Yeah, we came here from Greece, so please take care of us," The eighteen-year-old stated in a somewhat bored voice before turning her head to look at Sekijiro.

"Right, both of you, please go sit at whichever empty desk you find fit. We don't have any announcements this morning, so go ahead and get to know each other," The teacher said gruffly as he grabbed his papers and started for the door, allowing his students to chat.

Nico went to the back and sat down at a window seat, behind a tall guy with what looked like a speech bubble for a head. Clarisse walked to the other desk and sat behind a redheaded girl that had a gentle smile on her face.

Nico was silent, and Clarisse was chatting it up with the visibly stronger students, a small smile on her face as she spoke with them.

His silence was interrupted, however, by a blonde guy dragging a chair over to Nico's desk and sitting on it, his piercing blue eyes boring into Nico's own, dark eyes.

"What do you want?" Nico said sharply, glaring darkly at the stranger. Instead of being scared, the blondie laughed softly and waved off Nico's question.

"So, kid, what's your quirk? It has to be pretty strong if someone your age was let into the hero course," The guy said in an incredibly annoying tone of voice. Nico sighed and stared at him in full silence for a moment before speaking, still sharply.

"I can control shadows and use them to travel. Now can you have the basic decency of telling me your name, rather than immediately showing off how much of a prick you are by only caring about my quirk?" He said, trying his best not to have too much of an edge in his tone of voice. The guy only smiled wider and placed an open hand in the middle of his chest.

"I'm Monoma..! The best member of class 1-B, and the guy that's going to finally push class 1-A off of their high horse..!" He said as if it was his role or something.

"Okay then, why don't you leave me alone? I don't feel like talking to pretentious assholes, Monoma," He growled out, and nearly laughed when Monoma's previously dreamy look turned into one full of spite.

"Hey, don't talk to your seniors that way. You're lucky that I'm nice enough not to beat you into a pulp," Monoma said, frowning deeply. Nico only laughed when a shadow drew over the blonde.

"Hey, kid, what do you think you're saying to Nico, huh?" The memorable voice of Clarisse called as she leaned over Monoma, much taller, bigger, and stronger than him. The two demigods grinned evilly when their classmate quickly walked away after muttering several apologies to them.

"Nico, come hang out with me and the others. I can easily make you an honorary Ares kid, don't worry," She said, dragging him up to his feet and taking him over to the strong students. One of them was the ginger from before, along with a buff guy with white hair and a tall, brown-haired guy with glasses and a beard.

With that, Nico smiled as he spoke with his classmates, who turned out to be much nicer than Monoma.

Percy looked around at the halls, taking in the sight of the surprisingly clean school. They soon stopped in front of the last door, and most likely Aizawa's class. The teacher pulled the door open and walked inside, followed closely by Percy and Thalia.

The talking immediately stopped, and the students all ran back into their seats as soon as they entered. It was pretty obvious that Aizawa was a strict teacher, much to Percy's annoyance.

"Hello, class. I know school hasn't been going on for very long, but we have a group of five transfer students coming in today, two of which are in this class," He said, motioning to Thalia and Percy.

Percy hesitated, his mind had wandered a bit when he had noticed several students turning to look at the two new desks in the back of the class, obviously meant for the new students. He jolted out of his thoughts when he heard the daughter of Zeus speak in her usual commanding voice.

"My name is Thalia Grace. I'm a transfer student from Greece. The guy to my left is my idiot cousin, so don't mind him too much. Oh, and just call me Thalia. I hate my last name," She said before slapping Percy's back, obviously because it was his turn to speak. He gave her the stink eye before speaking up as well.

"Hi, my name's Percy Jackson. Also from Greece. I'm not as stupid as she says I am, so don't think much of it," He said as he scratched the back of his head. Aizawa was obviously sick of their introductions because he simply motioned for them to go sit at the empty desks.

Percy took the desk to the left, just behind a short, brown-haired girl with bright pink cheeks. Thalia sat on the other side of the room, behind a tall girl with long, black hair tied in a ponytail.

Aizawa droned on about things that Percy didn't really understand well, before simply leaving the class and allowing his students to mingle before their first real class.

The girl in front of Percy turned around to look at him as soon as the door closed behind the teacher.

"Jackson, right? Nice to meet you! I'm Uraraka!" She said in a bubbly, happy voice.

Percy laughed softly before responding, "Uh, just call me Percy. It feels weird to be referred to by my last name. And… it's nice to meet you too, Uraraka," He said awkwardly with a small, nervous smile.

He had noticed some blonde guy glaring at him from across the room but didn't get to confront him about it, considering people kept on walking over and speaking to Percy.

"Hello! My name is Iida, I hope we become good friends, Percy"

"Hi Percy, you can call me Tsuyu, if we're going on first-name basis."

"Yo, Percy! Hopefully, we can be good friends! You look really manly."

The conversations were interrupted by a loud THUNK, and the sound of something hitting the floor.

Percy frowned and turned his head, only to see a little kid with purple hair sprawled on the ground, a seething Thalia standing above him. He paled and shot up to his feet, walking over to Thalia.

"You okay? What happened?" He asked, genuinely worried for both her and the kid – he looked almost dead.

Thalia's electric blue eyes turned from the kid to Percy, nearly burning a hole into his head.

"That- little- shit- decided that a proper question to ask a new arrival in his class is 'What's your cup size?'. So, I answered him with a boot to that little perverted skull of his," As if to prove her point, Thalia ground her heel into the back of the kid's head, which must have hurt quite a bit, considering those were her combat boots.

Needless to say, it was a somewhat eventful morning.

Annabeth strode into the classroom, a bit awkwardly at first before the teacher waved her over. He was tall, with most of his body and face covered. All she could tell was that his skin was a bit tanned and that he had black dreadlocks spilling from under his cowboy hat.

"Hi, you must be Chase. Please introduce yourself to your classmates, then go sit in the back there, beside Shinso," He pointed to a gloomy, purple-haired guy that was sitting in the back, beside a window. Annabeth nodded before turning to look at her new classmates.

"Hello everyone, my name is Annabeth Chase. I'm a transfer student from Greece and came here with four other people. It's nice to meet you all, and I hope we can all get along," She said, before giving them a small, curt nod and walking towards the seat beside this Shinso guy's desk.

Annabeth sat down and placed her bag on the hook on her desk, then turned to look at Shinso once the teacher was done talking.

"Hi, you're Shinso, right? It's nice to meet you," She said, giving him a small smile and waiting for him to respond with what Annabeth would hope to be something friendly.

He sighed and looked at Annabeth, he looked incredibly exhausted, even more so than when Percy had the curse of Achilles.

"Yeah, that's me. I'm guessing your friends are all in the cooler courses? Probably the hero course," He said, obviously annoyed already. Annabeth forced herself to look at him with a sweet smile.

"I mean, they're in the hero course, but I can understand why I wasn't let in either. My quirk isn't exactly good for fighting, unfortun-" She was interrupted by his tired voice.

"No need to act like it's fine, I can tell you're pissed about it. The same thing happened to me," Shinso said in a bitter tone, looking at Annabeth with- was that pity?

"Hey, wait, you're not allowed to pity me. If we're in the same situation, don't you dare look at me like some abandoned puppy, got that?" She said, for once not thinking about what she was saying before saying it. Shinso smiled when she said that, his eyebrows raised.

"Wow, I already broke your nice act? That was easy," He said in a calm, controlled voice. Annabeth stared at him, first in surprise, then smiled widely and laughed.

"Oh- wow this is awesome. I can't believe that this is what you do with a person you just met for the first time..!" She said through her laughing fit, "You're so weird..!" Annabeth exclaimed.

Somehow, with their little interaction, Shinso suddenly looked like he got a full night's sleep.

"I'm glad I can suddenly make good friends this fast. Wait, no, that's just cause you're as weird as I am," He said softly with a small snicker.

Annabeth grinned at Shinso, "So what's your quirk? I bet it's actually something really good," He seemed to tense up a bit at her question but responded nonetheless.

"It's called brainwash. I can control anybody, as long as they've talked to me before I activated my quirk," He said, looking down at his desk in what looked like… shame..?

"That's a really cool quirk! How did they not let you into the hero course with a quirk like that? It's so helpful!" She said, letting her shock come out.

"You… don't think my quirk is a better fit for a villain?" He asked, to which Annabeth scoffed.

"It doesn't matter what the quirk is. Can a quirk be evil? Can a quirk be good? It's the person that decides, not the power. Honestly, a healing quirk could be as villainous as your quirk if it were used by a villain. It seriously doesn't matter," She said, leaning her head into her open hand.

"Okay… in that case, what's your quirk?" Shinso asked, a bit more confident and obviously surprised by her statement.

"Oh, I call my quirk 'Improv', I'm able to adapt to different situations and take in minor details to form a bigger picture, which helps with strategizing and improvising in stressful situations. Like just now, I could tell your quirk is something you're somewhat ashamed of, since you never once asked me what mine was even if I mentioned it, and you looked away from me when you told me what it was," She said with a small grin, " I guess my quirk could also be considered villainous"

With that, Shinso grinned. Annabeth was happy to speak with him, as he was obviously quite intelligent. They talked to each other about everything and anything, until the bell rang, indicating the start of their first-period class.
