A/N: This three-shot idea is more base on Anime in general, mix with Final Fantasy XIV Lore into the PJO universe. I guess pretty much a PJO X FFXIV one-shot with Isekai theme. It does involve Caleo because the first battle will involve both Leo and Calypso. If you don't know the Lore in FFXIV, do not worry, it'll be explained in this three-shot. If you ARE interested, try out the game itself. It's really fun and has such an amazing story for a MMORPG, despite it's long log-in waiting queue.

Anyways, enjoy the story.

Our story begins with a new character, his name is Daniel Cooper. He is just your ordinary guy who loves to read books, play video games and watch anime. He was just on his way to College when suddenly he and he got hit by a big flashing light underneath him. He was blinded for a moment, then ended up falling on a cabin. No idea of where he is, falling from the sky, and an angry teenage girl was the last thing Daniel needed. To make matter worse, monsters went and attack the camp. Daniel and the girl barely made it out alive, but the monsters were still on their tail. Will Daniel have to fight the monsters? Will he ever know what got him into this mess in the first place? And will the teenage girl ever stop being mad at Daniel? Find out now!

At Band Camp

Several cabins were destroyed, a couple were burned. In the center of the camp was a giant mechanical dragon and two teenagers, searching for one of their friends.

"She has to be here, Piper!"

"I know Leo, but-"

Leo kept shouting for their friend.

"Calypso!"

No one replied to his calling.

"Leo!" Piper yelled. "I'm sure she's okay, you need stay calm."

"But Pipes, Calypso could be hurt, kidnapped or..."

Leo hesitated at the last word, fearing it may come true.

"Don't worry, we'll find her. I promise," Piper said as they continue searching for Calypso.

"Please... please gods," Leo prayed. "Not her too. I can't lose her."

Meanwhile

Calypso, the titan goddess, is chilling at a diner with a man who apparently fell from sky, just like her boyfriend, and now are on the run from monsters. She sigh, hoping to have a peaceful summer and eventually come home to patch things up with Leo.

Then this happened.

"So you're telling me, that you have no idea why those monsters are after you?" She asked.

The man shook his head as he was eating a burger at a diner in the middle of nowhere.

"Yep," He said. "I was just minding my own bussiness and heading to class in college, then suddenly a giant magic circle popped out of nowhere under me, then BAM. I'm somehow on the air falling to a cabin. How I am alive, I do not know."

Calypso groaned, for she may not be able to go to band camp ever again.

"Whatever, just tell me about the summoning circle. Was it a Greek-style magic?"

"Nah, looked like your everyday Isekai summoning circle."

"I'm sorry what?"

"Isekai, you know. Your everyday cliche summoning to another world anime?"

"Anime?" Calypso asked confusingly.

"I'm sorry... you don't know anime? What, you been living under a rock?"

Irritated, Calypso replied, "No, I've been living in an island for 3,000 years."

The man snickered, "Okay that was a good joke."

"It wasn't."

He was confused for a moment. "Wait... seriously?"

She nodded.

"So what?" He asked. "Are you an immortal goddess? Powerful witch? Well... least you're not in a child body... we already have enough loli's already."

Calypso is so confused at every sentence he says.

"First off, who are you?" She asked.

"Daniel Cooper is the name. Nothing special about me; I play games, watch lots of movies and shows, mostly anime; read books too, favorite series is the Percy Jackson franchise."

"What?!"

"Ah it's nothing," He said. "Just a long running book series that left me with a bitter-"

"How do you know Percy Jackson?" She asked.

Daniel looked at her confusingly, "I read the books? It's a pretty popular book series, they're even making a Disney plus series about hi-"

He stop mid sentence when he realized something.

"You're Calypso and you were serious about being stuck on an island for 3,000 years, weren't you?"

Calypso nodded.

Daniel was processing everything and put it all together.

"OhmygodIwassummonedintoPercyJacksonworld!"

He suddenly internally squealed.

"This is a dream come true."

"What do you mean?" Calypso asked.

"Well, you see," Daniel explain. "If I was ever summoned to another world. My top five choices, in order, are: Star Wars; Supernatural; Percy Jackson; Dragon Ball Z and then Final Fantasy XIV"

"I'm sorry... why?"

"First off, It's Star Wars."

"I get that," Calypso said. She had time to watch the Star Wars movies, but don't tell Leo. She'll never hear the end of the jokes.

"Second," Daniel continued. "Supernatural is like and grown-up version of Percy Jackson but with family and a sweet ride. Oh, and some emotional family moments."

Calypso was already lost. "The heck is Supernat-"

"And third, Percy Jackson world because... well it's like Supernatural but for kids," Daniel gasped. "Wait! I can be a hunter in this world!"

"Wait hold on a mo-"

"In Supernatural, Hunters are people who go out, saving people and hunting things. The Family Business."

"Stop!" Calypso yelled. "Just stop and listen for a moment."

"I'm sorry! I'm just so excited!"

Daniel was acting like a kid who just made it to Disney World for the first time and just met Goofy.

"Look," Calypso took a deep breath, "Let's just start at the beginning."

Daniel nodded and relaxed for a moment. He explained how in his world, Percy Jackson and his friends are part of a book series, taking place from when he was 12, to the end of Apollo's Trials. He even mentioned stories of heroes from other myths. However, what got Calypso most was the fact that he knows about both Percy's and Leo's time at her island.

"So," Calypso asked. "In your world, everyone knows the tales of Percy and his friends?"

"Yep, from his first quest to the end of Apollo's trials."

"And you know all of his friends?"

"Personally? No. Briefly? Yes."

"But you also know about both Leo's and Percy's time at my island as well?"

"Yeah... there's no sugar coating it. Lots of people knows."

Calypso groaned, "Can this get any worse?"

"They're making a Disney plus Series about Percy."

"Just stop."

"Be cool if it's connected to the MCU."

"Stop!" Calypso yelled. "I need a moment to process."

"Sorry," Daniel said. "I just... I'm also processing this too. I mean, I didn't think being summoned to another world is possible; hell, even if it's real in the first place. Let alone meeting Calypso."

The titan goddess sighed, "I'm sorry, just having a really terrible day."

"I thought you're use to disasters falling from the sky."

Calypso snickered at that comment. "Really?"

Daniel shrugged and smile, "What can I say? Leo's a great role model."

Calypso shook her head as the diner host came and ask if they want refills. While they were eating, they were discussing about the summoning circle that brought Daniel here.

"So you never seen that magic before?" Calypso asked.

"Nope, magic doesn't even exist in my world. It's basically everything that's the mist and that's it. No gods, no magic, no monsters unless you count Reddit mo- you know what I'm just gonna be quiet."

"Best idea yet," Calypso replied. Daniel snickered at the comment.

"See? This is why I think I'd love to hang with you."

"Because of my insults?"

Daniel scoffed. "Please, if words can kill, I'd be dead the moment I stepped into high school. No, I just love you snarky sassiness; reminds me of TFS Alucard, just less bloodshed."

"Who's Alucard?"

"A perfect being for another time. Anyways, the magic circle was definitely not Greek-origin nor Rome. In fact, I don't think I ever seen such symbols on it before."

"Ancient?"

"No, more like, not from our world. Well... both our worlds."

Calypso was very confused but replied, "Let's just put a hold on this conversation until we get to Camp Jupiter, the others would want to hear this. They might be able to help you get back home."

Daniel nodded. "Sounds good to me. But anyways, how's it going so far?" Daniel asked.

"I'm sorry?"

"You know, being free from your prison? I mean, being isolated and imprisoned for 3,000 years can take a huge toll on your mental and social state.

Calypso scoffed. "That's an understatement."

"What do you mean?"

"I take it you know the issue with me and Leo?"

"Oh... yeah..." Daniel said. "Sorry..."

"It's fine, once I get home, I'm gonna talk to Leo about us and work it out. He's an idiot, but I love him."

"Good... that's good," Daniel said.

"You were worried there, why?"

"Well, remember when I said that in my world, people read stories about Percy and his friends?"

She nodded.

"Well, when they read about Leo falling to your island, most thought, 'Oh boy, here we go again. Leo's gonna try to charm another woman.'"

Calypso laughed while Daniel was smiling at his memory of when he read that part.

"But then, something happened none of us has expected it."

"And what's that?" Calypso asked.

"You..." He answered. "You opened his heart. You made him fall in love. It... it shocked me. More than Percy and Annabeth ever did, and I read about FIVE books in less than a year," Daniel chuckled. "But you and Leo? God, I prayed for a happily ever after for you two. I mean, two heartbroken people, looking for a counterpart; looking to make a connection. It... I never felt such strong dedication to a fictional relationship before OR since."

After he stopped talking, he took out his phone.

"What are you doing?" Calypso asked.

"Let me see if... YES!" He yelled and gave his phone to her.

"Look, I'm still connected to my world! Of course, I still have no phone service so I'm gonna try that phone station there. But look!"

On the phone was pictures and texts about both Leo and Calypso, being happy; being angry; being sad; just being themselves. This put a small smile on Calypso.

"Wow, I can't believe many actually care about us."

"Of course, you both suffered too much. You both deserve happiness. Anyways," Daniel stood up from the booth and put down his burger. "I'm gonna try that phone station and see if I can contact any of your friends. Do you by any chance have Annabeth's number?"

Calypso nodded and gave him her number. Why she doing this? Call her crazy, but she felt like she can trust this man. Even if he is a little hyper and weird.

"Thanks, keep looking at Tumblr, but not too much. There's... not every post are good things."

Daniel waits as the phone was ringing.

'Please work, I need to explain everything to them! Hopefully we can find out what's going on and maybe bring me back home.'

As much as he loves to stay and have adventures in this world. He has a life back home, even if it's dull and repetitive. He has friends and family that cares about him. No tragic backstories or any traumatic losses. His life was normal, but the people in his life are too precious to let go.

Finally, the phone answered.

"[Hello?]"

"Yes, hello? Is this Annabeth Chase?"

"[...Who is this?]"

"My name is Daniel Cooper, I have a lot to explain. But first, I'm with a young girl from ba-"

"[Calypso?! Is she safe?!]"

"Y-yeah, she's safe, we got attacked by monsters and are heading away from Band camp. We're at a diner nearby heading down to the nearest city. I was hoping if you and your friends can come pick us up?"

"[Are you a demigod?]

"No, I'm 100% a mortal. I can see the monsters but... it's a lot to explain at the moment, but I'll talk about it when we're safe."

"[...Okay. I'll trust you for now. Keep going down the street, you'll be at a small town. Leo and Piper are out there looking for her. I'll let them know and they'll come pick you guys up.]"

Daniel sighed relief. "Good, I'll go tell Calypso and-"

As he go look at where Calypso was sitting, she was gone. He dropped the phone and ran toward the booth. Everything was still there except Calypso. He started freaking until he looked at his phone.

"Crapbasket," He said. He ran back to the phone on the wall.

"Hello?"

"[What's going?! Is Calypso safe?!]"

"I don't know, I'm going to find her. She just ran off."

"[Why? Is there a monster?"]

"Worse... she looked at the recent posts."

After he explained the situation to Annabeth, he went out to look for her. She shouldn't have gone far since we're at diner in the middle of a forest. Luckily, he managed to pay off our food at the diner with the cash he had in his wallet (his card doesn't work in this world unfortunately). As Daniel ran out to find her, he heard a small whimper behind the dumpster. He ran towards it and found her, crouching on the floor, crying.

Daniel apologized.

"I'm sorry, Calypso. But I did warn you."

"...You said people cared about me and Leo."

"And I meant it."

Calypso stood angrily and looked at him with tearful eyes.

"You call that caring?!"

"Calypso, listened-"

"No! This isn't about me, understand? I knew from the moment Leo saved me from my island, people would have a negative opinion about me. I knew... But what hurts me the most..."

Calypso was about to cry again before she can speak, but held together.

"But what hurts me the most is what they say about Leo."

"Leo?...Oh..." Daniel said.

"They said that he should've never landed on my island. That I wasn't necessary; That I should've been a villain or get beaten up from Leo's friends... That..."

Both were quiet, because they knew what she was gonna say.

"That I was just a mistake."

Calypso sat back down and cried on her knees as she said that.

Daniel sighed. He hoped that Calypso wouldn't look at the posts recently. He knew that the two were going through a rough patch. He was scared that their relationship was gonna fall apart. Like...

"Calypso,"

"Just go... Tell the others they don't have to bother with me. I won't do anything rash. If I just ran away, maybe that'll make everyone happy. It might make Leo happy."

Daniel stood quiet for a moment, then sat next to her as she cry out her sadness.

"Look, Calypso, we both know that people are ALWAYS gonna hate other relationships. You think Percy and Annabeth are popular? Trust me, I've seen people talk crap about them online. Hell, People been writing fan stories about Percy joining Chaos because everyone abandoned him for a younger Son of Poseidon; even Annabeth. First of all, that's stupid idea of a story. But, I won't judge; I'm a writer myself so I respect their devotion to such a story, even if it's not such a fun idea for me."

Calypso was still quiet about that comment but had a small smile.

"And then another popular story idea, Shipping Percy with Artemis!"

"I'm sorry, Artemis?" Calypso said as she was drying up her tears. "She hates men."

"EXACTLY! Yet, because she actually respected Percy, people are now shipping them! I mean, why?" He said with a confused look. "But, like the Chaos story, I respect their opinions and devotions. But, it's just not my cup of tea. Percy loves Annabeth and is too loyal to abandon everything. He denied immortality for Annabeth, he fell down to Tartarus for her, he dreamt a future with her."

Daniel looks at Calypso.

"And you know what? Back at Camp Jupiter, when Leo met up with everyone. He had a worry look. He was worried about you."

"Me?"

"Yes, even when you guys fought, he misses you."

"Why?!" Calypso yelled. "Why does he care so much about me?! I pushed him away, denying his promise to return! I argue with him nonstop! I always get angry with him! So why?! Why does he love me?! Why do you care about me?! Why do I deserve all of this?!"

"Because Calypso," Daniel replied calmly. "Just as Leo does, we both believe you deserved happiness."

Daniel patted her head, as if she was just a child being bullied. Not a goddess who was entrapped for 3,000 years on an island or a fictional character that is being hated by fans.

Just a normal 16 year old girl, suffering for internet slanders.

"Listen, no matter how much you tried, you can't make everyone happy. I should know..."

Calypso froze when he landed his hand on her head, trying to comfort her. It helped if only a little.

"Instead of caring what random strangers say online. You should care about what your friends think. Do they hate you? No. Why? Because right now, Leo and Piper are out there looking for you."

"What?" Calypso said.

"Yeah, when they heard your band camp got attacked. Annabeth said that they're both out there looking for you. Everyone is worried sick about you."

Daniel stood up from his spot.

"Listen," he continued. "Don't let other people's opinion get to you. Only care about the ones YOU care for.

He reached out a hand to her, to help her get up.

"It's your life, Calypso. Live the way you want to."

Calypso looked up at him and sat there for a bit, contemplating on his advice.

She took his hand.

The drove on down toward a small town after they finished up their food from the diner. How they got a car? Calypso learned a trick or two from both Leo and Annabeth.

Daniel never stole anything in his life. So he was feeling really bad about it.

But, you gotta do what you gotta do.

"Feeling better?" Daniel asked as he drove. He was above driving age AND has a license.

"Not really, but I'll manage. I just... I need to... I don't know."

"If it makes you feel better, I got a unique quote to haters or bullies that'll make you feel so much better."

"What's that?" she asked.

"Sword Art Online Abridged Episode 11 Timestamp: 12:44."

"W-what?" she said confusingly.

"It's on YouTube. Leo or Piper can find it for you. Quote's in there."

"Then why can't you just say the quote?"

"Who knows, someone out there could be reading about us. I wanna make it more difficult for them," Daniel said with a smirk.

Calypso sighed at his foolishness. Reminds her of Leo.

How much she misses him. How much she needs him now more than ever. Truth be told, she's still hurt at the posts from his world. But the fact that they talk about Leo is what got to her the most. Before meeting Daniel, she met up with Annabeth for forgiveness and advice. The posts on Tumblr only strengthen her point about being nothing more but a mistake and a burden to Leo.

She needs to see Leo as soon as possible. She needs to know if she was ever worth saving.

"Hey Calypso?" Daniel responded.

"Yeah?"

"It's summer, right?"

She nodded. "Yeah?"

She looks ahead and see why Daniel asked.

"So then why is this town having a snowstorm?"

TO BE CONTINUED

A/N: Hope you enjoyed that, even if it was just crazy talk at the beginning. This was supposed to be a One-shot, but the story expanded into being a crazy anime arc that I decide to do it as a three-shot instead. Right now it's just about how Calypso would react to her haters. And probably how my OC would try to comfort her, tell her that no matter what, Leo still loves her. Like I said with both fanfics of Chaos!Percy or Pertemis, I respect those writers ideas and devotion, but it's just not my style. As for the haters, I respect their opinions and this is just nothing more but a fan story. I will not convert others to love Caleo nor will they convert me to hate it.

Anyways, I'm gonna finish up the DBZ three-shot first and then I'll continue this story. We'll call this AU the Daniel Cooper AU since it's about my OC.

If you also have any questions about this AU, comment or PM me and I'll answer to the best of my knowledge. Until next update.
