Background & History (Other details will be added later on in the story): Tatsuya was born with immense powers as two of his grandparents were gods and the other two were powerful beings of power. He also holds the lost spirit of the Ice Dragon King, Isreel in his blood after the dragon king sealed himself into a human body for eternal slumber until someone, powerful enough to reawaken him again. He lived peacefully until the age of 6 when he lost his parents and his powers awakened. He used his powers to kill the killers of his parents and after that he decided to train himself to become a stronger person so he can find the one who sent the killers and kill him. He went around and met each of his grandparents and asked them to train him. They did and in less than 5 years, he learned all of the skills and techniques that they all taught him. After learning these skills, he went around the world, doing mercenary work and bounty hunting while honing his skills and practicing and learning new techniques. He met various people and helped them while trying to find the true culprit behind the deaths of his parents. During his travels he became fascinated with weapons, mainly swords so he began collecting them. He has participated in the Devil Civil War and fought alongside with Sirzechs Lucifer and the other Maous against the Old Satan Faction. Not only that he also participated in the Heaven rebellion and fought with the Seraph against rebel Angels and the Grigori revolt where he fought together with Azazel against rebel Fallen Angels, causing him to be well known by the leaders of the three factions. He later joined the Underworld's Special Forces, Cero who are known for doing mercenary work for various supernatural factions while allied with the Underworld. There he gained the codename 'Alpha', given to the strongest member and leader of the group. Due to a certain incident, he left the group and began traveling around the world again. After traveling for a some time, he decided to settle down in the same city where he was born in Japan.

Norse Magic: Magic of the Norse Mythology. The spells of the Norse Magic are divided into four groups depending on the number of seals needed and the strength of the spell. The four groups are 1 seal, 3 seal, 9 seal and 27 seal. However the 27 seal is a group of forbidden spells because of its destructive nature and the amount of magic power it uses is off the charts and therefore is only allowed to be used by the Norse Gods, mainly Odin. However as his grandson and because of his high magic power, Tatsuya was able to learn some of the most powerful 27 seal spells and all of the 9 seal, 3 seal and 1 seal spells.

- Draupnir: A ring that creates originally 8 new rings every nine days. Originally has no purpose but was modified by Odin to hide his Norse powers and his True Norse Form. It was also modified by Odin to make sure it would not make any new rings until the current rings were broken. Tatsuya is able to destroy one ring or multiple at a time which allows him to slowly unlock his Norse powers. The ring is numbered 1 to 8 and is located in 8 different places in the body and must be broken in order. The order is right wrist, left wrist, right shoulder, left shoulder, right leg, left leg, brain and lastly the heart. Rings 1 and 2 unlocks his 1 seal Norse magic spells, rings 3 and 4 unlocks his 3 seal Norse magic spells, rings 5 and 6 unlocks his 9 seal Norse magic spells and finally rings 7 and 8 unlocks his forbidden 27 seal Norse magic spells and his True Norse Form.

- Colada and Tizona: Twin swords belonging to the Spanish Hero, El Cid. They have the power of frightening opponents and confusing them depending on the strength of the user.

- Excalibur (8th fragment): The 8th and lost Fragment of the Excalibur. Also called the "Forbidden Fragment" of the Excalibur. Created from the original hilt of the original Excalibur with a new blade made by Hephaestus. It has all of the same powers as the 7 fragments (not as strong) with the added power of not bleeding or fainting from critical damage when using the sword. However because it's too powerful, the blade cannot withstand the use of the power and so after extensive use, the blade cracks and could break. This causes Tatsuya to frequently ask Hephaestus to strength the blade.

- Muramasa: A Japanese demonic sword known to be cursed and bloodthirsty. There were many Muramasa swords but Shinto Faction destroyed most save a few. The blade is hungry for blood and must draw blood before it can be sheathed again. Overuse of the sword causes the wielder to become bloodthirsty. Tatsuya can suppress this blood thirst for at least 15 minutes before succumbing to it.

- Different types of weapons from normal swords to unique weapons like shurikens and Chinese hooked swords and magical weapons. (Names of magical weapons will be added later on when they appear) Weapons appearing so far: Kophis, Rapier, Twin Scimitars, Multitude of swords.

Harem: Raynare, Kalawarner, Mittelt, Gabriel, Tomoe Meguri, Serafall Leviathan, Kuroka, Xuelan, Karlamine, Mira, Yasaka, Murayama, Katase, Yubelluna, Ravel, Xenovia, Kunou, Inari, Kuraokami, Uka, Rossweisse (WIP)

This is my OC profile for my first fan fiction. I will try to update it regularly whenever I can. I hope to have the next chapter done in the next 2-3 weeks. (fingers crossed)

I wanted this OC to have no sacred gear and just rely on powers that he gained through training and through the blood of the different beings in him and although he might seem pretty strong already from the beginning, he will be facing lots of powerful OC characters and of course characters from the light novels.

Issei's Harem will still be the same ones from the book: Rias, Akeno, Asia, Koneko, Irina, Ravel, Ophis. (May expand his harem to include other characters like OC's, Tsubasa Yura, Rossweisse, Isabela, Kunou and Kiyome Abe).

I hope this will interest a few of you. If you have any suggestions or ideas for Harem's, abilities or OC characters, please feel free to send me a message or a review. Thanks :)
