Harry Potter nor High School DxD belong to me.

English is not my mother tongue.

The pain was unbearable, as if a thousand knives were piercing his body at the same time. Harry knew he was dying. Voldemort's curse had hit him hard in the Forbidden Forest. Darkness enveloped his vision, and for a moment he thought it was all over.

When he opened his eyes again, he found himself in a hazy void, a tall, hooded figure in front of him. The figure emanated an imposing and undeniable presence. Harry knew, instinctively, that he was facing Death.

"Harry Potter," Death's voice was deep and echoing, as if it were coming from everywhere at once. "You have gathered the three Deathly Hallows. You are the Master of Death."

Harry swallowed, feeling a mix of fear and curiosity. "What does this mean? Why am I here?"

Death tilted his head slightly, as if considering his answer. "Your destiny in this world is complete. However, the balance between life and death, light and dark, is an eternal dance across all worlds. There is a place where your presence can bring about significant change, a world where demons, angels, and gods coexist and fight for dominance."

Harry frowned, trying to understand what Death was saying. "And what do you want me to do?"

Death raised a skeletal hand, pointing to a distant point in the void. "You will be sent to a newly reincarnated body in this world. Your skills and knowledge will be needed to maintain balance. Your presence in that world will bring a new level of power and wisdom that is needed."

"What do you mean reincarnated? What does that mean?" Harry asked, dumbfounded.

"Reincarnated as a demon. In this universe in which you will appear, angels, demons and fallen angels fight for power. Angels are creatures created by the Christian god. Fallen angels are angels who sinned and could no longer remain in heaven. The demons, in turn, were created by Lucifer and Lillith, but it is very difficult for a demon to get pregnant, which has led to a drop in their numbers. To solve this, pieces were created that can reincarnate humans as demons. You will understand better when you arrive in your new body."

Before Harry could protest or ask any more questions, Death spoke again. "You will be a demon. Fear not, this is just a different race, not necessarily evil. Demons gain power from sins, especially lust. You will understand this when you feel the influence of those around you."

With that, the void around Harry began to spin and distort. He felt himself pulled into a vortex, and the last thing he saw was the figure of Death disappearing into the darkness.

Harry woke up with a start, but something was wrong. He wasn't in the Forbidden Forest, nor at Hogwarts. The place where he was was completely different. The first thing he noticed was the sensation of a body different from his own. He looked around and realized he was in an unfamiliar room, on a soft bed, with a naked redheaded girl hugging him tightly.

"I must be dreaming," he murmured, trying to make sense of the situation. He tried to get up, but the red-haired girl, who he now knew was called Rias, mumbled something and squeezed him even tighter. Harry felt his face flush.

After a few minutes of internal struggle, Harry looked around the room, trying to find some clue as to what was going on.

Suddenly, memories began to flood his mind. He was... Issei Hyoudou. 

Memories of an ordinary but happy childhood. A friend named Irina, with whom Issei had had deep bonds since childhood. He saw flashes of happy times playing together, and then, the pain of separation when Irina moved away.

More memories came. Issei's adolescence was marked by an obsession with girls, a trait that Harry now felt pulsing within him, albeit in a less intense way. He saw the scene of Issei's death, attracted by a girl who revealed herself to be a fallen angel, killing him without mercy. And then, rebirth as a demon at the hands of Rias Gremory.

Harry took a deep breath, processing it all. He now understood that he was in the body of a demon, who had been saved and reincarnated by Rias. He also felt the influence of lust growing within him as he looked at Rias, realizing that this was a source of power for the demons.

Rias started to move on the bed, and Harry, or rather Issei, didn't want to look like a pervert. But something inside him knew that to survive in this new world, he would have to adapt quickly.

Rias woke up, rubbing the sleep from her eyes. "Good morning, Issei," she said with a sleepy smile, not noticing the confusion on his face. "Ready for another day of school?"

She moved closer to him and Harry felt the heat of her body against him.

Harry swallowed. "Yes...of course, Rias. Ready for another day."

As he snuggled back into bed next to Rias, feeling the warmth of her naked body against his own, Harry felt a strange sense of determination. He might no longer be in the world he knew, but he had a new mission. And, as always, he would do his best to face any challenges that came his way.

With that mindset, hugging Rias from behind, he brought his face closer to her ear, letting one rest on her hip and bringing the other to her breasts.

"Is this what you wanted, senpai? Turn your kohai into a demon, drag him to bed naked and make him appeal to your lust?" He growled in her ear.

Harry wasn't fooling himself. He was popular with the women at Hogwarts, but was always slow to take to the flirtations and looks he received. So, when he woke up with this naked redhead bombshell by his side, he didn't have much to discuss internally. Obviously, if Rias If you objected to any sexual contact, he would back off, but he would take the initiative to see what might happen. After all, Rias Gremory as one of Kuoh Academy's Two Great Ladies, every student of the said school's wet dream.

Long scarlet red hair that falls in soft waves down to her waist, shining like rubies in the light. His eyes are a deep blue, like sapphires, expressive and mesmerizing, capable of transmitting both authority and kindness. Her skin is pale, almost porcelain, contrasting elegantly with the vibrant color of her hair. Your breasts.

Rias moaned, but Harry didn't know if it was because of his words or because he pinched her nipple. "Probably both," he thought.

She pressed her delicious, round ass onto his erection, making Harry moan and squeeze her breasts tighter in response.

Rias then turned around, looking lustfully into his eyes. Harry wasted no time and crashed his lips onto hers, pulling her on top of him, squeezing her breasts even tighter than before.

They separate to breathe and he brings his lips to her pink nipple, massaging her other mound. They were soft and firm, and they were so big they couldn't fit in his hand. They were perfect for him. He lightly nibbled on her nipple, eliciting another moan from her. 

"Ahh, just like that," Rias sighed.

Rias slid her hand down to his shaft and began stroking it, guiding him to his honey pot. Her pussy was hot, wet and tight. 

Rias took the initiative, resuming the kiss and starting to rub against his member. I grabbed her ass and entered her pussy. Rias came down hard, her eyes shining with lust and need. Harry knew he had an above average dick, but she took it all like a warrior, her pussy massaging his member diligently.

She started bouncing and bouncing on his dick, moaning every moment. Her pussy tried to milk Harry with each thrust, and he knew this was the most pleasurable moment of his short life. 

He began thrusting into her from below, meeting her thrusts. When she stopped to twerk, he flipped them over, pinning her beneath him.

Harry looked deeply into Rias' eyes as he advanced his speed, making the bed creak. Rias panted cutely with each meeting of their hips. Seeing that she was getting close, Harry bent down to take one of her breasts in his mouth, while he brought his other hand to her clit, trying to speed up Rias' orgasm as well.

It was instantaneous. The moment he lightly bit her nipple, pinched her clit and thrust deep inside her, Rias arched her back, her mouth open in a silent scream and her pussy squeezed Harry's cock in a surreal and obviously inhuman way. He couldn't do anything, letting out a long moan and cumming inside her for a long time. More than ever before.

After a few moments, he pulled out of her and snuggled next to her, pulling her into a hug, placing a kiss on her forehead as she laid her head on his shoulder.

Harry was lying next to Rias, both of them panting after what had just happened. The silence in the room was filled only by the sound of their breathing as he tried to process not only what he had done, but also the whirlwind of conflicting emotions and memories in his mind.

Rias turned to him, still with a gleam of lust and satisfaction in her eyes, but also with an expression of curiosity. She knew something was different about Issei—or at least what she believed Issei to be. "Are you okay, Issei?" She asked softly, her hands caressing his chest.

Harry looked at her, struggling to find the right words. He knew he needed to tell the truth, but how could he explain something so complex? How to explain that even though he was in Issei's body, he wasn't the pervert she had resurrected?

"Rias..." He began, his voice still a little hoarse. "I... I'm not exactly who you think I am."

She frowned, confusion beginning to form in her eyes. "What do you mean by that?"

Harry took a deep breath, feeling like there was no turning back. "When you reincarnated me... something happened. Something that maybe even you didn't realize. I... I'm not Issei Hyoudou. At least, not completely."

Rias stepped back slightly, surprise evident on her face. "What do you mean, not completely? Who are you then?"

"I am...or was...Harry Potter, from another world." He looked into her eyes, waiting to see how she would react. "I was fighting a battle, and I was hit by a killing curse. When I died, I somehow ended up here, in Issei's body. His memories, his desires, they're all here, mixed in with mine. But, Rias, I'm not the Issei you knew. I'm someone different, with a past far removed from this world."

Rias's expression changed from surprise to a mix of disbelief and fascination. "So...you're telling me that someone else's spirit entered Issei's body when I reincarnated him?"

"That's what it looks like," Harry replied, unsure of how she would react to this revelation.

Rias was silent for a moment, processing the information. Then, slowly, a puzzled smile appeared on his lips. "That...explains a few things. I felt like there was something different about you, but I didn't know what it was." She touched Harry's face gently. "So, Harry Potter... you still have the will to protect and fight, like Issei did. Maybe that's not so bad after all."

Harry relaxed a little when he saw her reaction. "No, I still want to protect those around me. But, Rias, I need to understand what this means for me, for us, and for this new world."

Rias sighed, leaning back on the bed and watching Harry closely. "Now that you have shared your truth with me, Harry, I think it is only fair that I explain more about what it means to be part of my clan and the responsibilities you now carry as a demon."

She paused, choosing her words carefully. "I am Rias Gremory, heiress of House Gremory, one of the 72 families of demon nobility. As part of the nobility, each upper-class demon has their own 'peerage,' a sort of group or 'family' that functions as a team. Each peerage is made up of different members, each with a specific role based on a chessboard. These members are known as 'pieces', and are reincarnated as demons through a set of chess pieces."

She pointed to herself. "I am the King, the centerpiece and leader of the peerage. My orders come first, and it is my duty to protect and guide all members of my clan." Her eyes softened as she continued. "But I do not see my peerage merely as servants or soldiers. They are my family, and I protect them with my life."

Rias then began to list the members of her peerage. "Akeno Himejima is my Queen. She is my closest friend and a powerful magic user, especially with lightning. Koneko Toujou is my Tower, a strong and silent girl, but extremely loyal. Kiba Yuuto is my Knight, fast and skilled with the sword. And finally, we have Gasper Vladi, my Bishop, who is a half-vampire with the ability to stop time in small areas."

She paused, letting Harry absorb the information before continuing. "Now, you, Issei, or Harry, are one of my Pawns. Pawns may seem like the weakest piece on the chessboard, but in truth, they have enormous potential. Just like in chess, pawns can be promoted if they reach the opposite side of the board, becoming any piece they choose, except King. This means that, with training and dedication, you can become much more powerful."

Rias got up from the bed and began to pace the room, her thoughts becoming more focused as she explained the responsibilities he would have. "One of the main obligations of noble demons is Rating Games. These are strategic battles between parties, where we use our pieces to fight on behalf of our family. These battles are more than just displays of strength; they are crucial to gaining prestige, territories and, sometimes, resolving disputes between families."

She looked back at Harry, her gaze serious. "These games are not only a tradition, but also a way of measuring the power and influence of families. Losing could mean losing honor or even territories. But winning can bring us respect and power. You will be expected to participate and fight at my side, just like the others."

Rias then approached Harry, sitting next to him again. "I know this is a lot of information, and that it all must seem strange, coming from where you come from. But I believe you have an important role to play in my peerage, Harry. There is something special about you, something that will other than just being a demon or a human. Let's figure it out together, and who knows how far we can go."

Harry nodded slowly, feeling the weight of Rias' words and the responsibility that now rested on his shoulders. Although the world around him was completely new and different, he felt that with Rias and the other members of his peerage by his side, he could face any challenge this new world brought him.
