Harry Potter and High School DxD do not belong to me.
English is not my mother tongue.
Harry woke up in his room, in Issei's body, feeling even more confused than the previous day. Issei's memories and his own seemed to constantly clash, fighting for space in his mind. He knew he had to adapt quickly, but the sense of strangeness persisted.
After getting ready, Issei went downstairs for breakfast. His parents were in the kitchen, and although the interaction was cordial, he felt disconnected. "They really don't realize that something has changed," he thought, as he left the house and walked toward the school. But his mind was elsewhere. Would the magic he always used still work in this new body? And how would it integrate with demonic powers?
Arriving at the school, Issei went directly to the Occult Research Club, where Rias and the rest of the peerage were already gathered. When he entered the room, everyone greeted him with nods and smiles. Rias, sitting in her usual chair, seemed to be waiting for him.
"Good morning, Issei," she said with a welcoming smile. "Come, sit down. We have a lot to discuss today."
Issei approached and sat in one of the chairs in front of Rias's desk. "Rias, I need to better understand how things work around here. I... I'm still adjusting."
Rias nodded, understanding. "Of course, Issei. There is much you need to know. First, let me explain something important about our school and the city."
She paused, ensuring she had Issei's attention. "Kuoh Academy, and the city itself, are under my protection and that of Sona Sitri, whom you may know as Souna Shitori, the student council president and, like me, a high-class devil. We both work together to maintain peace and protect this territory from potential threats, whether they be angels, fallen angels, or other devils."
Issei nodded, trying to absorb the information. "So, Sona is also a devil? And she is responsible for security along with you?"
"That's right," Rias confirmed. "We share the responsibilities but are always in contact to ensure everything is under control. Keeping the school and the city safe is one of our top priorities."
"I see," said Issei, as his mind wandered to the matter of magic. "And what about devil magic? How does it work?"
Akeno, who was beside Rias, intervened with a gentle smile. "Devil magic is a combination of three main factors: imagination, willpower, and demonic power."
She paused, letting Issei absorb the words before continuing. "First, imagination. It's the ability to shape magic according to our creativity. The more vivid your mental image, the stronger the magic. Imagination is the key to shaping your magic."
"Then comes willpower," Rias continued, leaning closer. "The willpower you put into magic is essential. If your willpower is weak, the spell will be weak. The stronger your determination, the more powerful your magic will be. A devil with a strong willpower can use their magic in more complex and powerful ways."
Koneko and Kiba observed the explanation, nodding when appropriate. Akeno added, "Finally, demonic power. This is the source of energy that fuels everything. The more demonic power you have, the greater the reach of your magic."
"So magic is shaped by imagination but fueled by willpower and demonic power?" Harry asked, trying to connect the concepts with what he knew of magic from his world.
"Exactly," Rias confirmed. "Besides the three pillars, we use magic circles and pentagrams to increase the precision, power, and stability of spells. They function as focal points to channel and amplify our power, making spellcasting more efficient. They are generally used for teleportation. In some cases, we use command words or incantations to shape the magic or invoke specific effects. For more complex spells, rituals are needed, involving creating specific environments, offerings, or the presence of certain elements that strengthen the magic."
Issei absorbed all this information, feeling a bit overwhelmed but determined to learn. "I see. So demonic magic combines imagination, willpower, and demonic power and uses tools like magic circles and pentagrams to enhance the spells."
"Exactly," confirmed Rias. "With time, you'll learn to control and harmonize these elements. At first, it may seem complicated, but with practice, you'll adapt."
Issei nodded, feeling grateful for Rias's patience and clarity and the other members of the peerage. "Thank you, everyone. I'll practice and try to understand how I can use this magic in the best way possible."
After the explanation, Issei decided it was time to test what he had learned. He left the club and went to a more isolated area within the school, where he could practice without interruptions. He sat on the ground, crossing his legs, and closed his eyes. He took a deep breath, trying to feel the magic inside him. For years, he had learned to access his magic through a wand, channeling his energy through that instrument. But now, without a wand and in a new body, he needed to find another way.
As he thought about this, he began to analyze his current situation. He had been Harry Potter and had also been just Issei. Now he was a mix of both. Obviously, it would take time to adapt, but he started to understand that he was not just Harry in Issei's body. He was both Harry and Issei. So he decided, even though it might not seem so important, that he would think of himself as Issei Hyoudou. It was confusing. Maybe he should try to learn Occlumency again.
Focusing, Issei returned to his original task and tried to cast a simple "Lumos," imagining the tip of his wand lighting up. To his surprise, nothing happened. Frustrated, he tried again, this time raising his hand and focusing on the sensation of his magic flowing through his fingers. Again, nothing.
"Well, magic works differently here," he thought, reflecting on the differences between his original world and the one he now found himself in. Issei then remembered Death's words, about how he had been reincarnated and how his soul had merged with Issei's. "What if magic is tied to the soul, not the body?"
This idea seemed plausible. If his soul carried the essence of his magic, perhaps he could access it in a different way.
Determined to try again, Issei closed his eyes, concentrating on what he had learned from Rias and Akeno. "Imagination, willpower, and demonic power," he repeated to himself, trying to organize his thoughts.
First, he focused on his imagination. He visualized the light of a Lumos. He closed his eyes tightly and imagined the light emerging in the palm of his hand, vivid and bright, as if his wand were there.
"Now, the willpower," he thought, channeling his determination to perform the spell. He felt the burning desire to see the light shine in his hand. At the same time, he tried to feel the demonic power within him, an energy different from the magic he knew, but equally potent. This energy, though different, also had certain similarities to the magic of his old world. Here, Issei theorized that demonic power and the magic from Harry Potter's world had combined when he was reincarnated, likely as a result of the souls merging.
To his surprise, the tips of his fingers began to glow faintly. A small light, weak but clearly present, flickered for a moment before disappearing. "I did it," he whispered, feeling a wave of relief.
The feeling of accomplishment was momentary, but he knew there was still much to be done. The spell was weak and unstable. "I need to master this. I need to better combine these three elements."
Issei spent the rest of the afternoon practicing. With each attempt, the light became a little stronger, and he began to understand better how his imagination, his willpower, and demonic power combined to create magic. He started to feel more confident, realizing that this new kind of magic could indeed be more powerful than he had imagined.
"This is just the beginning," Issei thought, knowing that he was only scratching the surface of what was possible in this new body and with this new power.
The day had been long and exhausting for Issei. He had spent hours experimenting and practicing, trying to master the new form of magic that now flowed through his body. Although he was used to magic in his old world, the combination with demonic power brought challenges and possibilities he had never considered before. However, after numerous attempts, he finally managed to control small spells, feeling more confident in his new reality.
Later, while still in the Occult Research Club, Issei approached Rias, who was reviewing some documents. He hesitated for a moment, but then decided.
"Rias," he called, and she looked up to meet his gaze. "Would you like to spend the night at my house?"
Rias raised an eyebrow, surprised, but soon a smile played on her lips. "Are you sure about this, Issei?"
Issei nodded, feeling more secure in his decision. "Yes. I want to talk to you, and... I think we need some time alone."
"I accept," replied Rias, her voice soft and laden with an implicit promise.
Shortly after, the two left the school and headed to Issei's house. His parents were home, but he knew that if he was careful, he could take Rias to his room without them noticing. When they arrived, he signaled for Rias to wait outside while he made sure the coast was clear.
With everything in order, he discreetly led her to his room. Once inside, Issei closed the door behind them, and Rias looked around with curiosity.
"It's a pretty normal room," she commented with a playful smile.
"It is," Harry replied, laughing lightly. "Quite different from what I was used to at Hogwarts."
Rias sat on Issei's bed, looking at him with interest. "You mentioned that you were someone else before, but you never told me many details. Who was Harry Potter?"
Issei took a deep breath, sitting beside her. "Harry Potter was a wizard," he began. "I grew up in a world where magic was everywhere, but it was very different from the magic that exists here. I went to a school called Hogwarts, where we learned to control and use our magic through wands, spells, and potions. I had to face many challenges, including defeating a very powerful dark wizard who wanted to take over the world."
Rias listened attentively, her eyes fixed on him. "You were very powerful, then," she commented, impressed.
"I was considered skilled, yes," he replied humbly. "But power alone was never enough. I always needed my friends and allies to win battles. I used to lead, but always as part of a team. Here, I'm beginning to learn to use a new kind of magic, and it's been a challenge, but I'm adapting."
To demonstrate, Issei extended his hand and made a ball of light appear over his hand, something simple but effective.
"You are already adapting very well," Rias said, surprised by how quickly he had learned to use his new magic.
Issei smiled at her. "I think I'm beginning to understand how things work here."
Sitting on the bed, after he shared part of his story, Issei hesitated for a moment before touching on a subject that had been bothering him since he arrived in this world.
"Rias, there's something I've been feeling since I woke up in this body," he began, looking at his own arm. "There's a presence, a kind of power that seems to be dormant here. I can feel it, but I'm not exactly sure what it is. It feels… different from demonic power."
Rias frowned, curiosity and concern mixing in her expression. "You feel a presence in your arm?" she asked, leaning in a little closer to examine Issei's arm. "It might be related to the Boosted Gear."
"Boosted Gear?" Issei repeated, trying to recall Issei's memories that were still confusing.
"Yes," Rias replied. "The Boosted Gear is one of the Thirteen Longinus, extremely powerful sacred artifacts. It houses the spirit of the Red Dragon Emperor, Ddraig. Issei, or rather, you, have that power within you. What you're feeling might be Ddraig, who is still asleep. With time and training, you'll be able to communicate with him and unleash his true power."
Issei reflected on what Rias said, feeling a mix of relief and anxiety. "So, this presence… is a dragon? And you think it will awaken if I manage to connect with it?"
"Exactly," Rias confirmed. "But that's not something that happens overnight. It takes time to master a power like this, especially for someone who is adapting to a new body and a new reality. But with patience and practice, you'll get there."
Issei nodded, feeling a bit more prepared for what lay ahead. "Thank you, Rias. It's good to know what's really going on."
"Don't worry," she said, her expression softening. "I'm here to help, and together, we'll discover what you're capable of with the Boosted Gear."
She moved closer to Issei, placing a hand on his face. "You're truly impressive, Issei… or should I say Harry? Regardless of who you were, you're someone special to me now."
Issei felt his heart speed up at her words. The closeness of Rias, the warmth of her hand on his face, all of it made him want to get even closer. Without saying anything else, he leaned forward and captured her lips in a gentle but full of feeling kiss.
Rias responded to the kiss, her hands sliding up to Issei's neck, while he pulled her closer. The connection between them was undeniable, and the desire they both felt grew with each passing moment. Issei's hands gently explored her back, feeling the softness of her skin through her clothes, while Rias pressed him against her.
With a delicate move, Rias pushed Issei back, making him lie down on the bed as she stood up and slowly undressed, putting on a show for him. Her eyes were gleaming with a mix of desire and affection. "Let's continue what we started," she murmured with a seductive smile.
Issei nodded, watching the spectacle unfolding in front of him. Rias was almost perfect. Her breasts were beautiful, large, with small, perky pink nipples, which seemed unusually firm despite their size. It was probably due to the physiology of a devil.
Rias finished undressing and approached Issei again. He tried to use his magic and, surprisingly, his clothes came off his body and appeared beside the bed.
Willpower, indeed.
Rias's pupils dilated with lust at the casual display of Issei's power. She positioned herself over him, her face close to Issei's shaft, and lowered her already dripping pussy onto his face.
Issei was amazed. Rias's pussy had plump, rosy lips, and its scent beckoned him. He wanted to feast on her honey pot so much. And so he did.
Issei gave a long lick to Rias's pussy and realized he would have to eat her out very often. Her taste was sublime. He didn't know if all devils were like this, if it was something specific to Rias, or if it was because she was his king. He didn't care. He just wanted to continue his work.
The boy shuddered when he felt her hand wrapping around his shaft, and her breath on the tip of his penis made his heart race, which only increased when she licked the head of his cock.
Issei leaned in, running his tongue along her slit, making Rias shudder and moan, taking the head of Issei's penis into her mouth.
He hissed as her tongue swirled around him. Issei began to circle her clit with his tongue while inserting two fingers inside her hot, tight tunnel. She moaned at the intrusion, taking more of Issei's cock deeper into her mouth.
Rias started using her tongue on the underside of Issei's cock while she took almost all of his length. The grip of her throat nearly made him cum instantly. Issei knew he would have to improvise to make her finish before he spilled his seed down the devil's throat.
Issei had never given oral sex before, but as a good pervert, he had always read a lot about it. He lifted the fingers inside Rias's pussy, searching for the spongy flesh of her G-spot. At the same time, he placed his lips over her clit and began to suck hard.
Rias bucked and moaned around Issei's cock as he continued to press her G-spot. Now it was a race to see who would make the other come first. Rias took what was left of Issei's shaft into her tight mouth while caressing his balls and humming, increasing the pleasure he felt.
Issei moaned at this and felt his balls tighten, making him fight not to cum. He inserted another finger into her pussy and began licking her small pearl. In a desperate measure to make her cum along with him, Issei imagined a snake and tried to hiss at Rias's little clit.
It worked. Rias bucked violently on top of him and arched her back, trembling hard. She moaned wildly, with Issei's cock lodged in her throat. The vibrations of her throat, along with its grip and heat, were too much for Issei, who emptied his balls directly into the bombshell redhead's stomach.
He feasted on her juices pouring over his face, still somewhat dazed by the force of his release.
When Rias recovered, she got up from the bed and snuggled next to him. "What was that thing you did at the end?"
"Did it work, then?" Issei asked, a mix of amusement and pride for the state he had managed to leave her in.
"Yes." Rias said. "Whatever you did drove me crazy. I was already close, but when that started, it was… I can't explain. It was too much." She continued happily, leaning in to kiss Issei.
Issei hugged her, pressing her body tighter against his. "When I was Harry Potter, I had the ability to speak with snakes. This ability makes my tongue constantly vibrate. I suspected I wouldn't have this ability anymore, but I'm glad to find out I was wrong."
Rias purred as she rubbed her breasts against Issei's chest, making him hard again.
He turned, pulling Rias into a lascivious kiss full of tongue, taking the opportunity to pinch her nipples, making Rias moan into the kiss.
Issei pulled away as Rias opened her legs for him, revealing her dripping pussy. Issei climbed on top of her, resuming the kiss as her breasts pressed against his chest. He aligned his cock and slid effortlessly inside her.
Rias's pussy remained as tight as the first time. It seemed to suck his cock as he tried to control his thrusts. Hot, wet, and tight. It was made for him. Issei was sure of that.
"Ohh fuck! Harder, Issei," Rias moaned.
Issei obeyed her orders.
He leaned over her and started hammering into her. Each thrust was stronger than the last, making Rias moan and throw her head back.
The scene was very sensual, and Issei began to lick and bite her neck. Rias crossed her legs behind his body, pulling him even deeper inside her.
Issei pinched Rias's nipples, pounding his cock into her with fast and deep strokes. Her pussy tightened more and more around his cock, feeling like a scorching vise.
They continued like that for a few minutes, moaning and looking into each other's eyes. Occasionally they would kiss and moan into each other's mouths.
It couldn't last forever. Issei felt her pussy tighten even harder and bit her neck forcefully, but without breaking the skin.
The effect was immediate, and Rias moaned gutturally, her pussy tightening and contracting around his cock in a shattering orgasm. It was too much for Issei, and he shot deep inside Rias's tunnel.
They stayed there, embraced, with Issei buried inside Rias, as they recovered from the intensity of their orgasms.
After catching their breath, they looked at each other for a few moments, the comfortable silence between them broken only by the soft breathing. Finally, Rias snuggled next to him on the bed, and Issei wrapped an arm around her, feeling the tranquility take over them.
"Good night, Rias," he murmured, closing his eyes and enjoying the peace her presence brought.
"Good night, Issei," Rias replied softly, as both let themselves be carried away by sleep, with the certainty that they would face the challenges ahead together.
