  The Underworld

  The Fabled realm of Devils, Fallen Angels, and a host of supernatural beings. Within a magnifit castle, a young man diligently practiced his swordsmanship in the courtyard.

  "housand, nine hundred y-seven… y-eight… y-en thousand!"

  He lowered his sword, panting, and wiped the sweat from his brow. The sixteen-year-old had silver-white hair and sharp, intelligent glowing e eyes.

  Though his handsome features still held a trace of boyish charm, his demeanor possessed an unusual maturity and resolve.

  "No sg, Roy! You have one huhousand swings to plete today!" a cool, authoritative voice called from behind.

  "Yes, Sister," Roy replied with a resigned sigh. "She's always so serious during training," he muttered under his breath. "Not a shred of ess." He resumed his practice.

  Roy was a transmigrator, the how and why lost to the mists of time. His current name: Roy Lucifuge.

  At first, he'd been doubtful, but after several years in this world, the reality was undeniable. He was living in the world of High School DxD.

  Devils, Fallen Angels, Youkai, Spirits, Angels... even Dragons and Gods—beings of myth and legend were real here.

  The woman who'd just spoken was his older sister, Grayfia Lucifuge. In the inal story, she was Sirzechs Lucifer's Queen, renowned as the stro of his peerage, the Silver-Haired Annihition Queen.

  However, in this reality, things were different.

  Born into the prestigious extra-demon House of Lucifuge, Grayfia's family had served the Old Satan Lucifer feions.

  During the Devil civil war, she'd fought for the Old Satan Fa, eventually g with Serafall Leviathan for the title of stro female Devil.

  Though she didn't win, her power rivaled that of a Satan.

  This elevated House Lucifuge to a position of power within the Underworld, indepe of the Lucifers. However, the war had decimated their ranks, leaving only Grayfia and Roy, the st male heir.

  Roy had initially believed that being born into a powerful Devil family, with such a strong sister, guaranteed him a life of easy power and a harem of beautiful girls.

  Riser Phenex, in that regard, was the embodiment of every Devil's dream. Reality, however, proved harsher. Despite his lineage, Roy cked any signifit talent for demonic power.

  After years of releraining, he was only a Low-Css Devil. His peers, Rias and Sona, had already reached High-Css.

  He'd beeed to give up, but Grayfia's unwavering belief in him pushed him forward. Her strict training regime was a stant in his life.

  Unfortunately, this also earned him a reputation as a talentless failure within the Underworld. He didn't let it bother him.

  "y-housand, nine hundred y-seven… y-eight… y-nine… one huhousand!"

  He finished his sword swings, his arms shaking, s down his face. He was too exhausted to even wipe it away. And this was just the beginning of his daily training.

  "Take a break, Roy. We'll start magic practice soon," Grayfia said, a rare smile softening her usually sterures.

  "Alright, Sister," Roy gasped, colpsing onto the ground.

  After a short rest, it was time fic. Years of practice, hampered by his ck of aptitude, had yielded only a handful of basic spells:

  teleportation, memory manipution, magic bullets, healing, and, most importantly, the tract magiecessary for f pacts with familiars and prospective servants.

  Of course, f a peerage required Evil Pieces, something he didn't yet possess.

  The world of High School DxD was a fasating pce. While humahe majority, true power resided with the Devils and Gods.

  Above even them were beings like Ophis, the Infinite Dragon God, and Great Red, the True Red Dragon God Emperor—entities at the very apex of power.

  In such a world, Roy refused to be ordinary.

  He wouldn't stand idly by while the girls he admired ended up with someone else.

  If he couldn't be ordinary, he would be extraordinary. Lag magical talent, he'd dedicated himself to the sword. While others pyed, he trained. While others rested, he trained.

  His relentless dedication had honed his swordsmanship to an exceptional level. He was fident that no one in this world could match his skill with a bde.

  In his past life, he'd been Regur Joe. But now, reborn into this dangerous aing world, he would achieve his dreams. And to do that..

  He needed power!
