[Start of Chapter]

Percy's POV:

I walked down the street, music blaring through my earbuds as I left reality and nodded my head to the beat. Still drowning in music, I took a right onto the final street to reach my family's apartment in Manhattan, New York.

Cars honked from the side, and people bustled about in the midst of the afternoon on a hot summer day. I know I should've been in camp but I decided to take a break and stay with family to heal over what happened in the Giant War. How I lost… I shook my head, before I could reminisce about the life-changing events.

I wasn't wearing anything special, a pair of jeans, with a green shirt covered by an open aqua blue jacket with a pair of darks shades and stylish green Nike trainers. How could I afford that? Blame the gods, they had spoilt me with an infinite amount of money contained inside a credit card for all the help I'd given to them over the years. I had also received other rewards for the wars but I didn't want to list them now.

Picking up my pace, I fast-walked down the street, evading women with pushchairs and men in business suits.

Finally, I reached the bottom of my apartment. Entering the old building I had resided in for most of my life, I walked to the stairs and quickly dashed upstairs, taking multiple steps. I now stood in front of my mom's door and fished for my key in my pocket. I looked at the door carefully, and started remembering the time I tried to convince my mom to get a better apartment, a better life but she didn't budge at all; wanting to 'achieve it herself through her hard work and not from a god, otherwise what's the point of life if I'm handed everything?'

Granted, I understood her point but she should at least get something for everything she had did for me. I would spoil her someday with a house or something like that. Eventually with the the key in my hand, I pulled out my earbuds and tucked them into my shirt collar and pushed my shades onto my jet-black hair. I inserted the key, and rotated the handle and went inside and smelled them.

Blue cookies.

Even now, they made my mouth water and caused me to remember the amazing times I had with my mom causing me to softly tear up but I just pushed it away, not letting the tears start. Instantly, I took off my shoes and shut the door behind me after locking it and dashed to the kitchen. There, I saw Mom and Paul, both having a chat as they helped cook some food.

"Hey Mom, Paul, I'm back." They turned around startled until they realised it was me and just smiled. Paul removed his oven gloves and came to me as I gave him a hug.

"How are you doing Percy? Did the walk clear your head?" He questioned, and I was grateful for his concern but a lot of the time it was dangerous to worry over me.

I nodded my head to calm him. "Mostly, I almost mulled over it until I just ignored it and carried on." I looked down at the floor while I sat atop the counter, rocking my leg back and forth. "But it's not good enough. It still hurts so much." I said depressed.

Mom came up time and lifted my chin and looked me in the eyes and smiled. Just that smile from my mom made my world light up with hope, and I smiled genuinely back. "At least you're improving right?" She said it as more of a statement than question. "That's what matters, just have hope. No seventeen year old child could have endured what you have but you did. You - my son. So you need time."

The happiness lasted only a minute before I killed the nice atmosphere. "But it's so hard while I'm so close to Olympus. So close to the US, North America. Everywhere I go, I remember being there because we travelled across all of America. New York, San Francisco, Alaska." I whined. "I don't remember just about her but the others, I still can't believe she did that." I hopped off the counter and slipped onto a chair. Closing my eyes and leaning back, I finished off. "I just want to leave this world. I know it's harsh to my remaining friends but I can't deal with it and I don't know what I'd do if I lost control of my sadness and hatred. I just want to go somewhere else, and forget about this place like another country." With my speech, I leaned an elbow on the table as mom pulled out a steaming hot tray of blue cookies.

"Well… we might have something already planned about that, son." Paul teased me with a grin I could feel. I looked up shocked, what did they mean? "All we need to get are the tickets." What? They already chose a country.

I stuttered in a hurry to know what they were talking about. "When is it? With who? Is it- I mean where is it?" I wanted to know so badly. I was shaking my leg in anticipation and nervousness. Mom just laughed at me, pulling her head back while Paul released some soft chuckles.

"Calm down Percy. Just grab a cookie and we'll tell you." Mom said to as I resigned to her order and took several cookies, mercilessly eating them all up. I could feel two stares on me, and I was confused until I looked I felt my face which was scattered with lots of crumbs, and my face grew hot.

Paul muttered to himself, which I heard. "I don't get how this kid can eat so much so quickly."

"Hey!" I yelled indignantly. Paul looked at me surprised with a raised eyebrow. "Demigod hearing?" I told him and he made an 'oh' with his mouth. "Anyway, I'm not a kid and it's not a bad thing, okay?" I said while biting into another cookie and relishing the feeling.

Mom interrupted the euphoric feeling I was having, yeah, I know, complicated words all thanks to- I stopped. Not thinking about her, I thought to myself. I looked at my mom as she began talking with some mirth in her eyes. For what though?

"Well, Paul and I wanted to go Japan once again tomorrow," I spat out some cookie at that. Tomorrow? They ignored the mess I just made. "due to how much fun you had last time with the school you went to temporarily, even if you knew next to no Japanese." They both looked at each and laughed, and I could've listened to it forever if it wasn't about me. I blushed to the tip.

"But mom… I did make some friends in my defence." I defended myself to stop them laughing. But it only worked them up even more.

Mom had tears coming out of his eyes while Paul while holding his stomach. Paul pointed at me. "And Percy, what did you do when you met her? You blushed!" I covered my face with my hands, and sighed.

"In my defence, she was really beautiful but I had my mind on someone else." I mumbled into my hands. "You guys suck."

The laughter slowly ceased until Mom placed a hand on my shoulder and shook me. "I'm sorry Percy but it was just too hilarious with how you reacted to the people there." She wiped the final tears from her eyes

I gazed at her and grinned. "I'll forgive you only if you make me some more cookies when we get there?" She was about to deny it until I used my puppy-dog face, and she relented with a sigh.

I decided to continue the conversation and looked at both of them. "So we're going Japan again?" I tried to keep myself from yelling with excitement when the full force of the facts hit me.

"Well, we really wanted to go to Japan so you could attend school there but you couldn't speak Japanese very well the last time we went." She said sadly and I felt guilty for lessening their experience. "So we will probably go-"

"Hey wait!" I interrupted. She glared lightly at me for interrupting but gestured for me to continue. "I can speak Japanese. She taught me since my second year at c-camp and before she left, I had mastered the language." I don't know why she had to teach me a language, she tried teaching me several but I just couldn't learn them and hated them until Japanese came up and it was so cool and interesting.

They both looked in surprise at me. Paul asked me hesitantly. "So you know Japanese?" I nodded.

I sucked in a deep breath and prepared myself to have a full blown up Japanese conversation.

"彼女が私をよく教えてくれたので、ええ。" (Yeah I can because she taught me well).

Paul as quickly and fluently replied. "私はあなたのことを誇りに思っています。" (I'm proud of you Percy).

I puffed my chest up and flared my nostrils arrogantly until I just let out all of my breath and fell into my chair.

Until a memory sparked. "And hey, I wouldn't wanna crush your dreams. I know you guys have been learning the language for a while, and if we didn't go, it'd be a waste of time." I spoke out with a point and a sly grin. "Unless during those lessons you had together, you-"

"Stop right there young man!" Mom yelled at me with a flustered look and red face, while Paul sat there silently with an equally red face. "You don't need to talk about what we do!"

I put my hands up in a surrender motion. "I'm sorry mom and Paul, but I just had to get back at you two for laughing at me." I then devilishly smiled again. "It's not like I would mind another sibling." I grinned hugely at their shocked expressions at how carefree I was.

I turned around and walked to the enter the living room when I sensed a cookie heading my way. I brought my hand up and caught it, and bit into it while snickering. I heard my mom groan in frustration at her failed shot.

"Demigod reflexes, Mom, demigod reflexes." I laughed at her without looking back.

Paul decided to help my mom and said something. "I'll make you and that girl you liked Percy, what was her name, oh yeah, Rias, meet up and you'll be blushing so hard, her hair will become jealous Percy!"

"I do NOT like her Paul, she was just a friend. And anyway, I'm mature now, I'm not going to go red." I waved off sensing my step father's devious smirk.

Not bothering to change or anything, I hopped into the sofa and switched the TV onto a random channel. Distinctly, I heard my mom say while pulling at her hair. "What will we do with that kid?"

I just chuckled to myself lightly and soon, my eyes closed. My mind going on lockdown, exiting the reality and entering the land of the dreams and before I did, I remembered a memory. A girl with crimson red hair and bright green eyes, the vision was too hazy to describe anything else as I saw her meet.. me?! Oh yeah, this was when I met Rias Gremory in Japan. The mist cleared to a world darkness where I was whisked away to the realm of dreams - or nightmares for me.

[Linebreak]

I sat up fully aware, breathing deeply as I calmed myself. The nightmare I had was of… her dying. I didn't want to say it but…

"Annabeth." I whispered to myself in sadness. A few tears leaked out of my shut eyelids, as I silently cried for her. "Why did you have to leave me?" I opened my mouth in a noiseless scream, letting out the agony residing in me. All I ever wanted was peace, but fate was cruel. Throwing me through battle through fights through war.

I wasn't afraid of the horrors, I was afraid of what they did - how I failed to save my friends, stop my friends from doing disastrous things or protecting my family. It struck my heart how I had to let go but it was what Annabeth wanted.

I grit my teeth to control myself but my body was on autopilot, letting tears freely fall and my body shake in uncontrolled sorrow. All I wanted to do was scream to my heart's content but that's not what Hazel would've wanted, Frank nor Annabeth.

"Why did it have to be her?" I mumbled through the tears.

After several minutes, my breakdown had stopped, as I wiped the tears off my face with my sleeve and widened my eyes to get my tiredness out. Thankfully, no one had woken up to which I sighed in relief at.

I twisted myself and put my feet on the floor as I sat on the comfortable sofa. Snapping my fingers lazily, the water molecules around me condensed to form water (courtesy of my own private training) which flew into the glass which stood still on the oak table in front of me. I reached my hand out and brought it up to my face, I had a few sips - after purifying the liquid - which rejuvenated me and then tiredly, splashed the rest over me. I dried myself after I was now full of energy with a click of my fingers.

I got off the sofa, and noticed the simple clock with digital time hanging on the wall.

'5:57am'.

I groaned at how early it was and decided to pack my bags for whenever we were going to Japan. Trudging to my bedroom, I opened the door and entered. It still looked the same as last week - sea green walls I painted, a nice aqua shade on the carpet. My bed sat in the furthest corner to my left, with a window gazing out over Central Park. In the furthest corner to my right was a cupboard which sat there with some dust on top of it. Residing next to it was a basket with clothes supposed to be in.

I honestly tried to be as tidy as I could to be helpful to my mom but it was difficult. Bits of litter poked out from the few clothes which lay there. My bin to the right next to the door was tipped over, garbage all over the floor. Over on my left was a cardboard box full of old toys with a rip on its side letting several toys fall out. On the very left in the corner was a drawer which held several other things like images and spoils of war. Next to it was an abandoned chair which had my clothes I wore regularly such as my hoodies. Finally, next to my amazing bed was a desk with a lamp on it for working.

My mind wanted to recall memories but I was stronger. I was going to the stronger. For Annabeth. For Frank, Hazel, Mom, friends and everyone that depend on me. I clenched my fist as I embedded this into my mind. Cutting that line of thought, I kneeled down to pull out my suitcase which I used during the summer before the Battle of the Labyrinth when I had a holiday Japan. It was a simple blue with black outlines as I preferred it simple but no, life just had to be complex for me.

I lifted the suitcase and dropped it on my bed, dust waves releasing from the landing which I waved away or I'd be in for a coughing fit. I unzipped it and left it open.

What would I take to another country? I didn't know if I wanted to stay so I just decided to take everything I had, even unnecessary things like my spoils of war. It didn't really matter to me as it was a gift from Hermes with each pocket able to hold infinite storage; I smiled at that, even if they didn't show it, the gods did care, well, some of them. I snorted at these thoughts.

Testing out Hermes' gift of profound speed, I used my energy zipping through everything in my room and shoved it under various pockets in my bag.

When I was done, I wiped my hands together at how quickly I did it. And then I realised, I still had a lot of time till my parents woke up; I should've taken my precious time. I huffed in annoyance.

Off to the side, was my old pair of clothes which I hanged out of. Quickly, I did the same thing with them and zipped it away.

Releasing a breath I didn't know I was holding, I opened the curtains and let the heavenly sunlight fall into my room. On my cupboard was a mirror which I stepped in front of.

I studied myself, wondering if I looked good. I had a dark blue pair of jeans, a buttoned up loose long-sleeved shirt without collars that was a nice shade of blue, lighter than my jeans, with wavy white lines falling down it. Over this was a bright blue puffer vest with a pair of Nike black and blue trainers. I had some shades tucked into the neck of my shirt while I smiled at my appearance. It's not that I wanted look amazing to society, it's just I didn't want to make a bad first impression I guess.

I patted my pockets to make sure I had my keys for my vehicle thanks to Apollo. My pen was also in my left pocket as always incase we ever ran into danger. My back pocket held my wallet with several different cards I didn't really need except one. And finally in my right was my space grey (I think it was) iPhone 6 Plus, given to me by Hephaestus so I couldn't be detected and cool features installed onto it, with some earbuds in the smaller pocket inside it.

I even decided to gel up my hair for once so it would stay in one place instead of flying about. Not bothering for the style I wanted, I settled for an easier one; all my hair spiked to one side with my sides flat and the direction was to my left.

I sat down on my bed as I finally had finished my getting ready for our trip out of this-this place. Even if it was my home, it held too many memories - good and bad - to endure for the rest of my life so I need some time and space away from the greek mythological world.

Pulling out my phone, I looked at the time and it was only 6:42am. I groaned in absolute boredom until I pulled myself together to make some breakfast.

On my way there, I saw Paul groggily enter the living room on this nice Saturday morning and we greeted each other with a polite 'good morning'. That was when he quizzically gazed me up and down.

He scratched his head. "Why are you ready?"

I looked at him confused. "Aren't we going to go before noon?" I asked him.

He then laughed slightly at me until the words he spoke made me cry in my mind. "You know we aren't going on our flight till the evening, right Percy?" He said as if confirming from me but he knew that I didn't know.

I just dropped onto the couch next to me instantly, free time meant catching up on sleep and who wouldn't want that? My eyelids dropped as I heard Paul mumble about 'demigods' and chuckle to himself which made me smile. Eventually, I entered the realm of Morpheus'.
