Author's Notes: This is my first time doing this so I know I'm gonna screw up to anyone reading, but first I don't own High School DxD or other elements I will add in the story, I just own the fanfic after seeing so many good ones on this site. Got my creative juices going. Anyway, OC intro. Update: This update is for what happens after Roxas returns from the Dimensional Gap. I know my character is a Mary Sue, so if you're not interested, don't read.

Sacred Gears: Boosted Gear (Not gonna bother explaining since you should know what it does) and Creation Gear. Creation Gear is a dragon-type Sacred Gear that allows the user to create almost anything based on their imagination, however its size limit is up to 1000 meters, but the Balance Breaker can go up to the size of a galaxy and it cannot create Sacred Gears. In terms of power, the Creation Gear is equal to the Longinus types. It houses the Cosmic Creation Dragon, Andromeda, a dragon that comes from the Andromeda Galaxy. Andromeda was one of the few beings that learned the secret of the begining of the universe and its creation and used those secrets to create her home galaxy. She left to find something interesting to do after spending time in her home galaxy, wandering until she felt a calling to her in the Milky Way. The Balance Breaker is called Cosmic Forgemaster, which allows him to go past his usual size limit to create things, but it exhausts his stamina and magic power to the point he sleeps for days, months, or even years. The purpose of this Sacred Gear is unknown, as it could be used to create a world of its own or if it's the God from the Bible's back up plan if things in the universe leads to destruction. Andromeda is a bit of a prankster as she painted Ddraig white and helped Roxas paint Albion red, but she is kind to others. But she did feel lonely as the only person who possessed her who could communicate with her was Roxas. Her feelings for Roxas developed as she was able to talk to others, and even got a crush on Ddraig.

Bio: Roxas Hyuuga is an American with Cuban and Japanese descent. He lives in South Florida, with his Cuban father, Japanese mother, and two sisters. He learned his skills in guns with his dad while learning swords and hand to hand with his mom. His hobbies in gaming, anime, manga, and robotic engineering gave him an interest in creating games and robots. His gaming hobby has given him a chance to go on pro leagues where he usually win more than $5000. He is a bit socially awkward in conversation since he likes to talk about his own interests with a somewhat profound knowledge, making others think he weird. Even after graduating college with degrees in game design, teaching, and computer programing, he finds difficulty in finding a job. That was until in the mail, he received a letter telling him that his skills are required in Kuou Academy. Thinking that its strange for a letter from Japan to reach him, he looked online to see what the academy was about. If he went, it wouldn't be the first time he went to Japan as he did spend some time there to see his mother's side of the family and go with his dad to Odaiba to see the life-sized RX-78-2 Gundam. After considering the offer, he thought 'What do I have to lose, at least I can go see grandma' and signed up a teacher and tech manager of the academy. That is where this story will begin.

His past is not what many would call happy. He was anti-social and stayed away from others until his best friend, Jack Patton, reached out to him. An incident involving him during his high school years with the death of his friend caused him to go out as the Tricky Rebel, who would fight gangs, thugs, and corrupt cops. When he gets caught, he would hack the police's records and delete his own data. Police are usually baffled as to how they never have any information on him. His Tricky Rebel days were meant to prevent others from becoming him, but it was also a means of revenge against the officer that killed Jack. It gets worse when he's involved in a rescue attempt of the city mayor's son. The commotion of Roxas and the thugs who kidnapped the kid caused the police to show up. An unknown shooter fires his gun and his bullet hits the child which kills him. This caused Roxas to lose control and rampage like a monster, killing everyone painfully and slowly until his mother stopped him. This part of his past haunted him until he was able to confront it after going with his marriage proposal to Rias and the other girls.

He's part of the Hyuuga clan of onmyoji, a secret to him that was kept until his parents told him about it. He was trained by his parents while never knowing the reason why he went through a training regiment that would normally kill a human. But in doing this training, he has gained the use of onmyojutsu, and even practices senjutsu. Thanks to his training, he is able to resist youjutsu to a degree. The question of him practicing it is unknown as he is also learning Norse magic and other magic schools.
