This story starts out with Percy running for his life from some hellhounds, but he was too distracted to notice that another hellhound appear out of nowhere it bit into his shoulder he killed the hell hound, but he wasn't anywhere near water to heal himself, but a certain redheaded well endowed young women was watching. She was thinking to herself he could be a very powerful alley she contacted her childhood friend Sona to teleport him to their dimension there Rias pulled out four of her pawn mutation pieces, and so Percy was asleep when he woke up he found himself in a queen sized bed and he was wearing black running pants with a black tang top he instantly checked his pocket and riptide was in his pocket Percy was thinking to himself "whoever wanted him here wanted to keep him comfy." Rias walked into the room that Percy was sleeping in, and said "oh good morning how did you sleep." Percy being startled reached into his pocket, and got riptide out of his pocket then uncapped it, and then Rias was startled by it she thought "that he was a normal boy, but by the way he carries himself he is very powerful", and Percy said "who the hell are you I was fighting a pack of hellhounds." Rias said "I am Rias Gremory Heiress of the Gremory Clan you are my servant." Percy asked "where are we." Rias said "we are in the underworld" Rias saw Percy's look in his eyes they were bulging, and Percy said "I have been to the underworld plenty of times, and this is nothing like the underworld that I know." Rias asked Percy what he meant, and he said "in the underworld that I know my Uncle Hades, Aunt Persephone, and my cousin Nico demigod son of Hades." So Rias said "My friend Sona and I brought your from your universe into ours." The look on Percy's face was of pure utter joy and happiness, and asked Rias to walk over to him and he said "thank you so much for doing that." Percy then kissed Rias, and she didn't even fight it at all Rias said "that was my first kiss hope you enjoyed it."
Percy was scared because he was starting high school in a different country and different universe, and so Rias asked Percy hold old he was and said "I am 18 years old." Rias said "that would put you in our grade." Soon the new school term started Percy was in the same class as Sona, Rias, and Akeno the teacher said we have a new student starting here so be kind to him.
Percy came in and said "Hi there I am Perseus Thorn Achilles Jackson or you can call me Percy for short." The teacher asked if anyone has questions for Percy and Sona asked "why is your hair a raven black, and your eyes sea green." Rias saw the pain in Percy's eyes Percy said "I got it from my father but after awhile he had another kid, and everything for me went down hill." Sona felt bad for bringing that up, and asked "what club are you in Percy." Percy said "I am in the Occult Research Club also the swimming club, and the kendo."
The week for Percy flew by fast, and it was Saturday Percy asked if he could go somewhere to meet someone she agreed but she had to come along he agreed, and Percy told Rias to close her eyes since Percy was a son of Poseidon/Neptune he could travel by using vapor, and so he appeared in the Olympian Throne Room Rias was hearing shouting but it suddenly stopped and she opened her eyes and said "Percy this is the Olympian Throne Room why would you bring us here." Percy said "You will see Lord Zeus may I talk with you and Lady Hera in private but I want Rias, and her family to listen to this."
Lord Zeus said "Yes she can have her family here Rias used a magic circle, and contacted her family, and her mom picked up" Rias mothers asked "Rias why are you calling where are you we are worried sick about you." Rias said "Don't worry mom I am in the Olympian Throne Room could you bring Dad, Brother, Sister, Millicas, and Sona with you my pawn Percy wants to ask Lord Zeus something." Percy said Lord Zeus the reason I asked for these people I want them to see my past but I don't want it leaving our group could also Lady Hera join us but can it be in private.
Lord Zeus said so why do you want to speak to me and my wife about. Percy said after you look into my memories with these people around I will tell you. Lord Zeus said alright. Both deities, and the guests looked into Percy's memories they where shocked at what happened to this young man, so they stopped and Percy dropped to his knees Rias and Sona both ran to him they just hugged then Percy's emotional dam broke he was crying, and so after an hour of crying he finally stopped then he said "Lord Zeus and Lady Hera the reason why I wanted to talk to you in private is the I want you to adopt me as your son but I still want to be a demi-god." Lord Zeus looked to his wife, and she nodded it was okay then Zeus said "Would you want to be adopted right now or make a big show out of it." Percy said "Lets make a huge show out of it."
When they returned Zeus said I Zeus Lord of the sky lighting winds and the king of the gods hereby adopt Perseus Thorn Achilles Jackson as my son if he accepts. Percy said I Perseus Thorn Achilles Jackson, Son of Neptune/Poseidon, Slayer of Titans, Bane of Kronos, Death of Monsters, Praetor of the Twelfth Legion, Bane of Giants, Killer of Gaia, and Slayer of Medusa, Polyphemus, Antaeus, and the the Minotaur thrice, Killer of the Nemean Lion, Rescuer of Zeus' Master Bolt and Hades' Helm, Leader of Armies, Bearer of the Sky and Achilles Curse, Survivor of Tartarus, One of the Seven, Friend of the Gods, Hero and Savior of Olympus twofold accept Lord Zeus offer. I was in shock as well the rest of the council suddenly my greek form and roman form where in perfect sync for once because of Percy having both greek and roman perfectly in sync with each other.
