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. I wanted to try out a fanfic after getting some help and wanted to do this myself.

Sacred Gears: Boosted Gear and Blade Genesis. Blade Genesis is capable of creating a sword with any ability and/or property, being able to break the normal logic of reality of certain properties. The Balance Breaker, Graveyard of Swords, projects his inner world of a field with swords impaled on the ground for him to use against his foes. Blade Genesis takes on the appearance of a gold bracelet with sword motifs and a large diamond gem, making it indistinguishable from crafted jewelry.

Bio: Katsumi was born and raised in Japan by his parents who are Dragons, taking on human form. Around the age of 8, he went on a school field trip, which will be the point that his life changed. Dragon Slayers went to his home and killed his parents for nothing more than wanting to kill Dragons. Katsumi received a call and heard the news, opting to return home. He comes back to see the police closing up the crime scene. Tannin, who he sees as an uncle, was there in his human form to see what happened and told him about the Dragon Slayers. With no one else to turn to, Tannin adopts him and allows him to live with him in the Underworld until he was old enough to be in high school. From that day, Katsumi hated anything that had to do with Dragon Slayers. He returns to Japan around the start of his high school years after spending some time with Tannin to start his now soon to be hectic high school years.
