Reborn as Rias Gremory with a Multiversal System
Reincarnated as Rias Gremory, the fiery crimson-haired heroine of High School DxD, she quickly realizes that life inside her favorite ecchi anime is far more dangerous than it ever appeared on screen.
Behind the glamorous façade of an elite devil princess lies a web of looming threats. The remnants of the Old Demon Faction coil in the shadows, the Calamity Group begins to stir, and catastrophic forces such as the Evil Tree and the Beast Emperor 666 threaten to plunge the world into chaos. Worse still, in the distant future stands a monstrous evil god powerful enough to overwhelm even the True Red Dragon God Emperor in mere moves and the mysterious Three Pillars, whose existence alone could shake the foundations of the underworld.
And then there’s her own humiliating fate: reduced to a provocative title and treated as little more than a background fantasy for others.
Refusing to remain a pawn in someone else’s story, Rias resolves to seize control of her destiny. No longer content with being a decorative “Switch Princess,” she sets her sights on absolute strength. Through strategy, alliances, and ruthless ambition, she will carve her own path, one of conquest, dominance, and survival.
In a world where gods, dragons, and devils collide, can Rias Gremory rise above her predetermined role and become the strongest being in existence… or will the weight of prophecy crush her before she ever has the chance?

I have a suggest if you want to make about Riser again. Someone reincarnated as Riser in the wedding day. He don't have a choice to accept Issei's challenge like canon. So he will make a condition for the duel, Rias's peerages will be his toys if he win. In the end, he can kill Issei. Riser's new life, he will be gantle to his peerages and cruel to Rias and hers in bed. Asia's sacred gear is having ability to heal, so I have a though that Riser will make her to use her ability to maintain the virginity of Rias's peerages (cannot use it in Riser's, because I think there's a long time that they're not virgin).
