Title: Death's Champion Reborn: Rias Gremory's Awakening


1. Prologue: The Last End and Rebirth Setting: After a thousand years of life as the Master of the Deathly Hallows, Harry Potter has seen the rise and fall of countless civilizations. He has mastered death itself, transcended time, and walked the realms of the living and the dead.

Event: Eventually, Harry decides to release himself from the burden of immortality, having lived far beyond the natural course of life. But instead of passing on, his soul is reincarnated into a new world—a world of devils, demons, and supernatural power. His new body is that of a young Rias Gremory, an heir to the Gremory family, though the memories of his previous life are sealed within her soul, hidden from her for now.

Conflict: Though Harry's soul is reborn into Rias, the experiences and weight of his long life as the Master of Death are buried deep within her subconscious. This creates a disconnection from Rias's current life—one filled with the politics and drama of the Underworld. The moment of his (her) rebirth sets the stage for a grand internal struggle: to balance the power and wisdom of the ancient past with the life that Rias Gremory is destined to lead.


2. A Promise Broken: Rias's Engagement to Riser Rias's Engagement: The Gremory family arranges Rias's engagement to Riser Phenex, a proud and powerful devil. For Rias, this announcement is more than just a political arrangement—it is a deeply personal betrayal. She has no interest in Riser and is deeply conflicted, knowing that she has no true say in the matter.

Harry's First Awakening: Just before the engagement is formally announced, Rias begins to feel a sudden surge of memories—fragments of a past life that do not belong to her. Memories of Harry Potter, his experiences as the Master of Death, and the weight of his responsibility begin to resurface. The connection to death is undeniable, and Rias (now Harry) struggles to come to terms with her new identity.

Confusion and Revelation: As Rias's engagement to Riser becomes the center of attention, Harry's memories become clearer, and she starts understanding the gravity of her reincarnation. She recognizes that she is no longer the girl she was—she is someone who has lived for millennia, someone who has touched the very essence of life and death. These realizations cause a deep internal conflict, as Rias must now deal with the trauma of her past while trying to navigate the challenges of her new life.


3. The Unfolding of Powers and Wisdom The Deathly Hallows Influence: As Rias regains more of Harry's memories, she discovers that she retains the powers and knowledge of the Deathly Hallows, albeit in a different form. The Hallows are no longer just relics—they are part of her very being, affecting the way she perceives the world around her. She can see death, manipulate souls, and understand the deeper workings of life and fate. These powers are ancient and dangerous, though Rias isn't yet fully aware of their full extent.

Struggling with Control: As Rias's memories of being the Master of Death flood back, she struggles with the temptation to use these powers. The ability to bend death to her will is intoxicating, and part of Harry wants to reignite that power to fight against the forces of destiny. However, Rias (and Harry) has learned over millennia that such power comes with heavy consequences. She feels the weight of her past decisions—choices she regrets and battles she fought in the name of controlling life and death.

New Life, Same Old Challenges: Despite the growing power within her, Rias (Harry) must navigate the complexities of her new life as a devil. She is now a young devil with the legacy of her family to uphold, a leader who must deal with the politics and schemes of the Underworld. Her newly awakened self brings a new level of wisdom, and she begins to see through the illusions of the devil world—its games, lies, and ambitions. But even with her knowledge, she is still bound by the expectations of her family.


4. Rias's Peerage: The Foundation of Loyalty and Trust Akeno as Queen: As Rias regains more of her memories, she begins to realize that Akeno—her most trusted companion—will eventually become her Queen. Akeno is not just a powerful devil; she is also someone with deep emotional ties to Rias, someone who understands her more than most. The relationship between Akeno and Rias takes on new significance as Harry's wisdom begins to influence her actions and decisions.

Growing Affection: As Rias becomes more attuned to her new self, the relationship between her and Akeno starts to shift. Akeno feels an odd mix of familiarity and awe toward Rias as the latter begins to tap into a level of wisdom and power she's never known. Harry's past self is drawn to Akeno, who shows loyalty and understanding, while Rias herself feels conflicted about the romantic implications of their bond.

The Rest of the Peerage: Kiba, Koneko, and the others also begin to notice subtle changes in Rias. The once carefree and somewhat naive Rias now possesses an aura of ancient wisdom and calm strength, and the members of her peerage find themselves looking to her for guidance more than ever. They begin to realize that Rias is more than just a princess of the Underworld—she is a force in her own right.


5. The Challenge of Fate and Family The Riser Problem: The engagement to Riser comes to a head as Rias (Harry) refuses to go through with it. The tension between the families escalates as Riser, in his arrogance, challenges Rias to prove her worth. This creates a situation where Rias must face Riser not just politically, but with the full force of her newly awakened powers. However, this is not just about Riser; it's a battle for Rias's autonomy, her right to live life on her own terms.

Confronting Her Family: The Gremory family, particularly her father, is unhappy with Rias's defiance, as they were counting on this engagement to secure alliances with the Phenex family. Rias must confront her family and the social pressures of her world, questioning the very system that binds her and her future. The battle becomes not only one of love and defiance but also a rebellion against a predetermined fate.

Emergence of Death's Champion: As Rias faces these challenges, the full weight of her powers emerges. She begins to understand that her purpose in this life is not to play the game of devils but to break free from the chains of fate. She realizes that the powers of life and death she controls give her the ability to change the world, but only if she is willing to accept her responsibility as a force of balance in the universe.


6. The Final Decision: Love, Death, and the Future Choosing a Path: Rias (Harry) must choose how to balance her immense power with her desires for love and freedom. Her deepening bond with Akeno leads to a powerful emotional climax, where Rias must decide whether to embrace her past as the Master of Death or forge a new path in this life with the people she's grown to care for.

Romantic Resolution: The romantic aspect between Rias and Akeno blossoms into something more profound. They understand each other on a level that transcends normal love—it is a bond of trust, loyalty, and shared understanding of the burdens they both carry. Whether they will become lovers or continue as close companions, the connection is unbreakable.

Endgame: Rias faces the future with new resolve—no longer just the heir to the Gremory family, but the Champion of Death, ready to confront whatever challenges come her way. She will redefine what it means to be a devil, reshaping the Underworld and perhaps even the very fabric of existence, all while navigating the complex relationships with her peerage, family, and the greater supernatural world.


7. Epilogue: A New Champion of Death Resolution: Rias, now fully aware of her past, uses her ancient knowledge and newfound strength to carve her own path in the supernatural world. She remains a force to be reckoned with, but she also becomes a protector—one who guides her peers and allies toward a future free from the constraints of fate.

Akeno's Role: Akeno, as Rias's Queen, will always stand by her side, perhaps even becoming her closest confidante. Their journey together has only just begun, and the love and trust they share will be the foundation of their future adventures.
