And so I'm back with another story. This is the outcome of the request Elements1999 (please check out his stories as well by the way) and it's another crossover! First of all, there are ZERO crossovers for Percy Jackson and Free!IH and I don't know how this will be taken, but I always love different things. This will be a three-shot and it takes place in the college years of Percy and let's say he is older than Haru by 4 years. Enjoy!

Disclaimer: I don't own anything and if I did, oh all the gay stuff that would happen *evil laughter*

It all started when Dad came over on a whim while I sat on the beach after my no-class-day wake-up time. Yes, Poseidon, the all-powerful-god-of-the-seas Dad. Summer has just began, and college classes in New Rome were postponed until a week later to give us a time-off. It actually meant to me as, and I quote, " ALL THE TIME IN THE WORLD WITH THE SEA!"

Annabeth slapped me on the head after I said that.

I mean who can blame me? I inherited my sea-loving genes from the god of the seas after all. There's noway that I wouldn't love the sea. Or bathing in it, or splashing in it or swimming in it or playing hide and seek in it with all the fishes, or - ah, I'm straying from the point again. Back to 'when dad came over'. Oh yeah, it was quite a surprise. I shouldn't have been, because I was simply sitting by the sea. And the god of the seas was bound to be there. But it still surprised me. No demigod gets visits from their godly parents so often, which is both a bad thing and good thing. Anyway, as I sat there thinking of what to do for the rest of the week, in the blink of an eye, he sat there, in his fishing chair, with a fishing rod, and a line which seemed to disappear the farther it went.

And then, I realized he was still a god, apart from being my father.

I scrambled to my knees in an awkward, two-knees-kneeling bow. "Father," I say in the most not awkward way I can.

He only chuckled in my state. "It's okay Percy, sit down, otherwise you look ridiculous," he said. Those are wise words of a god.

I sat back down, breathing in smell of the sea, the water gently lapping around my feet. I looked so calm, and I felt so proud. But then, holy cows what now, another prophecy? Another quest? This can't be happening, I'm finally living a nice happy life that's a bit more monster-free than usual. Oh gods, I promised mom I wouldn't get into anything dangerous so suddenly. And Annabeth told me not to do anything reckless, or decide anything for that matter. Oh gods, what am I going to tell them-

"Really, son, stop overreacting, there is no danger right now, except for the storm you would be brewing, literally, with your thoughts," he remarked, with a funny look and a quirked eyebrow. Well then.

"Yes, father. Forgive me. You merely surprised me." More like scared the wits out of me.

"Uhuh, I did, didn't I? Anyway, I have a quest-" I groaned in protest.

"Man-up, boy. I'm doing this quest with you." Oh, really?

"In fact, your mother approved." She did?

"And your bags have been packed. It's waiting for you in your dorm." Fast work.

"Annabeth has been informed as well." Wait, what?

"And we leave in about an hour, sponsored by Aeolous Airways and Zeus's consent. Oh we're going to the New York airport by the way" WAIT, WHAT?

"So if you have any questions, ask them now because after I answer, we leave for the air port." WAIT WHAT?!

I gulped, suppressing everything I want to say, and trying to pick my words in my head. "Where are we going? And how long are we staying there?" I asked, thinking those were good questions. Annabeth would be proud of me for thinking first!

He chuckled. "Japan. And about a week, give or take. I'll tell you all about it on the plane," he said.

Of all places, somewhere across the world, in the middle of the ocean, with the most renowned Tokyo Tower (I have Annabeth again to thank for that piece of information) and the land of the rising sun (more of Annabeth's information) and the land of anime and Hello Kitties (as seen through TV). And also, an awesome Ocean. I guess it won't be that bad.

"But mom-" I start to say.

"Will call us as soon as we arrive," he replied, tugging a bit on his fishing rod.

"But Annabeth-" I start to say again.

"Personally asked me to tell you to bring pictures regarding all sorts of architecture there. I have a disposable camera in your packed bag," he interrupted me yet again.

Doesn't leave me much of a choice now? This is happening in all sorts of fast.

"Lets fly to Tokyo then."

The flight itself was uneventful. Most of what happened involved sleeping and snoring, even though I'm ADHD. And did I forget to mention the flight was exclusive and first class? For a moment, I forgot my fear of of being on the air. And then a small turbulence happened. Dad sat upright looking around, as if the plane may fall any second. Then he sat back down, a vein pulsing on his forehead.

"Whatever, brother," he muttered.

Half-way through the non stop flight, I began to wonder why were we going all the way to Japan for? (Not that I mind. Japan has a freaking ocean!). Dad did say he would explain why. So-

"Dad, if you don't mind me asking, why are we going to Japan?" I said, sounding like a little boy.

"I did say I would explain. So here it goes. You already know the whole thing gods going to Earth and falling in love with mortals and having children-" Percy raised both eyebrows in surprise. Could it be… "And I know my personal life is my personal life, because you kids these days love 'privacy'. I'll get to the have a brother, four years your junior." Called it.

"Okay. So we are going to Japan to see my younger brother," I said trying to get used of the idea, and the way it rolled off his tongue. Younger brother. I have a younger brother. Yes, just repeat it all over again in your head.

"He could use some parental support, you know. He is in high school, about to graduate. He has a competition somewhere. Nationals, apparently. His mother invited me to see him swim at least. She says he is very good! And we actually get to meet him! Pretty exciting huh? Oh and his mom said something about him having a bit of a girly name. Hara, Hana, something." Poseidon said excitedly, probably dreaming up some awesome buff swimmer in his head. Now, I'm pretty curious. I can't exactly, delve into my father's personal life. But four years my junior? When I was four years old and that old prophecy was still taking place, he was stalking off in Japan? I don't even want to think about it.

Then again, he is my younger brother. And besides, swimming? Oh, we are going to be the best of friends!

"Afterwards, we can go around Tokyo. Kill a monster or two. Eat Blue Takuyaki. Probably visit my underwater villa and stay there for a bit. Play a little water hockey," Poseidon said casually, as if we did such things everyday. With a younger brother, no less.

Though it sounded kind of nice. Blue Takuyaki, sounds delicious. I don't know what it is but it's giving my stomach the Growl.

"Sounds like a plan, Dad," I said looking out the window, silently enthusiastic.

A younger brother. What's he like?

There are two sides to everything, just like how there are two sides of a coin. Being in a country, half way across the place you actually live in seems to sound so cool. In fact, standing in the Tokyo International Airport right now, call me the sap queen, but it's beautiful. Seriously, even I love the architecture.

"Dad, where's the camera?" I asked, apparently after looking around, to a person who wasn't there. This is the other side. Getting lost in the airport of a country you just arrived in, with nagging jet lag and a messed up time.

"Dad? Dad? Come on!" I looked around frantically. It's not that I am particularly worried. It's just he is a three bazillion year old god (maybe older, no?) who still has it in him, and quite literally, to have children with pretty women. Okay, I'm stepping over the line, forget what I just said.

"Oh gods, dad, of all times," I muttered, trying to find the exit from the international gate, while turning my head a round like an ostrich looking for my father with my bag in tow.

Now, see here, this was how I got into my first mishap of the day. Night. Whatever. Anyway, do you remember those cliche moments where the guy and the girl of the love story bump into each other and they both tumble to the floor in each others arms? I can't say I'm in a love story right now, because I already am in one way back before now, with Annabeth. So it happened like this.

Because of my being an ostrich in this foreign airport, I can't actually see the way I was going and ended up bumping into two people who also came rushing from the international gate. Down we go, with me facing the cold marble ground, and two heavy bodies on top of me. A few seconds later the two people stood up, and I sat up from my position, groaning because of my back a bit. Gods, that makes me sound old.

"Gomen, gomen. Daijoubudeska?" A guy with red-ish (kind of pink?) hair said, a hand held out for me to take.

I took the hand with a firm grip. "Daijaba the hut what?" I said, in confusion. French was not my favorite class, and I certainly did not take Japanese as well. French is hard enough as it is.

The guy laughed. "I see, you don't speak Japanese. I'm so sorry. Are you okay?" he said in perfect English with a Japanese accent. I breathed a sigh in relief, although I can't be too relieved now can I? For all we know, he could be a monster in hiding, though my senses aren't tingling.

"I'm alright. Thank Pete, you speak English. I'm sorry I didn't see where I was going," I said. For the first time, the red-head guy's companion. He had black hair, and that type of cool aura around him. At the same time, he was silent as he looked at my exchange with the red-head.

"No, no. It was our fault too. But, you do look a bit lost, Mr…?" he said, the last part trialing off in question.

"Percy, just Percy please." I said, filling in the question.

"Percy-san-" San? "-you look a bit lost. Are you looking for someone?" he said, nodding when he said my name, the 'r' rolling a bit.

"Ah yes. I actually am. Have you seen a man in khakis and a Hawaiian polo? A bit heavy , also has a beard?" I asked, hoping they saw him.

"Ah, yes I think. He left through the gate earlier. He was heading for the Takuyaki store," the red-head said.

The Takuyaki store. Figures.

"Oh, thank you so much for your help, Mr…?" I said, the last part trialing a bit in question like what he did.

He smiled. "Matsuoka Rin. This is my friend, Nanase Haruka."

"He-hello," Haruka, the black-haired guy said in a struggle and a heavy Japanese accent.

"He's not very good with English. Though, show him a pool and you'll be out of words. Anyway, we'll walk with you through the way out," Rin said, smiling politely. Swimming huh?

"Thanks. Nice to meet you, Rin, Haruka."

And that my friends is the first chapter of the three-shot. If you need any clarifications about the time setting as well, this is set around the last episode Free! Eternal Summer (season 2 if you haven't watched it) after Rin and Haru arrived at the airport. Apparently, it was around the same time Percy and Poseidon arrived as well ;) I actually like this idea. Again we have Elements1999 to thank for this request. Go check his stories out as well. See you all in the next chapter! (which I will be working on right now but I don't think I can't post until Friday night to Saturday morning-ish)
