Hello guys, this is my first fanfic here. This is an alternate universe of Highschool DxD. I do not own these characters except for the OCs.


Chapter 1: Prologue


Purple flames and ashes were the only things he could see. The burning ceiling and walls resulted in a cloud of smoke, blinding him to his surroundings. How could this happen? Things were perfectly fine a moment ago. He was having dinner with his mother when suddenly, an explosion occurred.

"Mother! Mother! Where are you?!" A young boy yelled out to his surroundings. This boy appeared to be 10 years old, with light-blonde hair with crimson eyes. He placed his arm in front of his eyes, trying to block the smoke that enveloped his surroundings.

The explosion sent him hurtling to the other side of the room. His ears hurt… His body aches… His figure was bloodied due to the explosion. Hell, it was a miracle he was still alive.

"Tristan! Are you okay?! Are you hurt?!" A voice came from behind him. He immediately turned around and saw his mother's figure amidst the smoke cloud. He released the breath he had been holding. He felt relieved to hear the voice of his mother.

"Mother!" The boy known as Tristan rushed to his mother, not caring about the pain and heat surrounding him. He saw his mother at a short distance when suddenly a light emerged near her. In an instant, a breeze of wind swept through the room, dispersing the smoke and allowing him to see his mother clearly, without the smoke's presence disrupting his vision.

'What was that? What is that light? How the heck did the smoke disappear in an instant?!' Amidst the chaos, many questions erupted from young Tristan's mind.

"Damn her! I thought we were out of the radar… that old bitch! It's been ten years, nothing has been going on ever since." His mother's anger was visible to the naked eye. He had never seen his mother like this; he had never heard her swear in his life. Even when something upset her, she never got mad. His mother was the gentlest and most caring person he ever met.

"Listen, Tristan, I need you to run and never look back. No matter what you hear or see, never stop running. I'll find you when this is over… okay?" His mother told him. But before he could respond, laughter echoed through the house.

"HAHAHAHA! Do you know how hard it is to find you? It's like finding a needle in a haystack." and all of a sudden, a figure emerged from the purple flames.

"Augusta! How dare you! You attacked my child, my home, and destroyed my house! I swear by my name, I'll kill you!" His mother yelled out, with malice in her voice. The witch known as Augusta glared at his mother. Augusta is an elderly lady, who wore a purple witch robe and a pointy witch hat. The purple flames danced on her hands, and if looks could kill, his mother would be dead.

"Alyssa, Alyssa… Do you realize that I could easily kill you and the brat easily? With a flick of my finger, your body would be engulfed by my holy flames, and only ashes would remain! So, don't make any empty threats, would you? Or perhaps, I could kill the brat first? Surely, his agonizing scream when the holy flames burn him alive would be splendid to hear." Augusta smirked. Her gaze now landed on Tristan. Making both Tristan and his mother's eyes wide, the former paled at the thought of burning alive.

Tristan was scared, no, he was frightened by the scenes displayed in front of him. Who was this Augusta? What is going on? How could she control those purple flames? What is going on?! Several questions popped into his head.

But his thoughts came to a halt when his mother suddenly attacked Augusta with magic.

The unexpected attack from Alyssa surprised Augusta. She took the attack head-on, having no time to react at all, let alone, create a defense barrier. A small explosion erupted from the place where Augusta stood at. The smoke clouded Tristan and Alyssa's vision.

"How dare you… How dare you raise your magic to me… HOW DARE YOU, ALYSSA AMBROSIUS! I am Augusta of the Purple Flame! The wielder of the Incinerate Anthem! For that I shall burn you both alive! Nothing will remain after that!" Augusta screamed. Her face was a bloody mess due to the magic that Alyssa casted onto her. Suddenly, spears made of purple fire emerged from the smoke, heading to Tristan head-on.

The revelation of the unexpected attack from Augusta made his brain shut down. He couldn't move, only waiting for the inevitable. He closed his eyes, waiting for the pain that would come when the spears reached him.

A second.

Two seconds.

However, the pain was never felt by him. So, he reluctantly opened his eyes. And what he saw, made a memory that would be forever etched in his mind.

"Mother!" In front of him, is his mother, with the spears impaled in her body.

"T-Tristan… You need to survive… L-Listen to me…." Even though there were spears embedded in her body, she still managed to speak. She grabbed his head and put their forehead together.

"AHAHAHA!" Augusta's wicked laugh echoed to his ears. Tristan peeked to the direction of the witch, and what he saw made him gasp. The purple flames danced on her hands, growing larger and larger by the second.

"You are so weak compared to your former self! The current you, will never defeat me! OHHH! The thoughts about burning your son alive make me feel alive! What a waste! For the descendant of the flower mage to be so weak and ignorant!" Her sadistic smile was visible on her face.

"F-Flower Mage…" Amidst the chaos, the sudden revelation regarding his lineage made his mind astray. Seeing the confused state the boy was currently in, Augusta's smile grew wider. Her sadistic smile is present on her face.

"My, my… Did you not tell the brat, Alyssa? Did you not tell him about his lineage? You, brat, have the blood of the Flower Mage, Merlin Ambrosius, coursing your veins…" Her statement made Tristan shocked.

How could he not? He was the descendant of Merlin. The strongest mage. The advisor of King Arthur Pendragon. The Court Magus of the Kingdom of Camelot. He always thought that the stories that his mother told him were only a fairytale, a fiction, but after seeing Augusta's capabilities to summon the purple flames, he doesn't think Augusta's words were lies. Seeing his mother's face, full of regrets and sorrow, confirmed his thoughts.

"I'm so s-sorry… I don't want you to know about this now… I have planned t-to tell you when you're older. I w-want to keep you away from the supernatural world as long as possible… I'm so sorry, T-Tristan… I wish we had more time together…" His mother's hand was on his chest. He was confused, how could he not be? What in the hell is going on? He didn't realize that drops of tears were starting to fall from his eyes. He grasped his mother's hand.

"M-Mama…" He said weakly, not having the power to speak.

"He will tell you e-everything… You must know that I will always be in your h-heart… and I-I will always love you, My Little Flower." Alyssa said while she coughed up blood, the leaking trails of blood tainted the beautiful face she had. With the last ounce of her strength, she whispered ambiguous words, which seemed to be an unfamiliar language to Tristan. Out of a sudden, a bright light emerged from beneath Tristan.

"BURN TO ASHES!" With Augusta's scream, the purple fire launched toward the mother and son duo.

"W-WAIT! What are you do-" He yelled to his mother. But it was too late; the last thing he saw was his mother's beautiful smile, and then the light engulfed him.


"-ing?!" He blinked his eyes. The loss of blood and the throbbing headache strained his body, casting a wave of weakness over him. Each blink felt heavy, as if the world around him blurred with each passing moment.

"W-Where am I?" He asked no one, his voice resonating in the empty room. He took a sluggish step, the strain in his body making it harder for each step. His vision slowly adjusted to his surroundings, and he realized he was standing in the midst of a laboratory. The stark contrast between the burning house and this laboratory left him bewildered. The air felt different–clean, devoid of the acrid scent of smoke. His senses, still recovering from the previous ordeal, struggled to comprehend the abrupt change of scenery.

Questions swirled in his mind. How did he end up here? What happened to his mother? The memories of the old witch and the menacing purple flames haunted him.

"M-Mother…" Tristan whispered, reaching out into the empty air, hoping that his mother would come to rescue him and assure him that the previous encounter with Augusta was only a nightmare – an event that had never unfolded in reality… He waited desperately, but to no avail. The soothing words of his mother never came, only the haunting silence greeted him.

Tristan took another sluggish step as he cautiously explored the laboratory, discovering that it was filled with unknown devices and technology. Screens on the wall displayed complex data, while holographic projections danced in the air. A seat surrounded by many screens and technology beyond what he had ever seen. Lastly, in the middle of the room, a chess piece rested on top of a pillar.

The sight of the laboratory amazed Tristan's young mind, leaving him both fascinated and unnerved.

Tristan's eyes fixated on the chess piece – a symbol of strategy and calculated moves – perched atop the pillar in the center of the room. The juxtaposition of the surreal surroundings and the mundane object intrigued him. With each step towards it, the strain in his body lessened, and a newfound strength emerged, fueled by an innate curiosity.

The holographic displays around the room flickered to life as Tristan approached the central pillar. Information scrolled through the screens, diagrams, and equations that seemed to dance in a language he couldn't comprehend. The chess piece, a king, emanated a faint crimson glow, drawing him closer.

As Tristan reached out to touch the chess piece, the sound of a door opening stopped him. He immediately retreated and hid behind the hologram projector. The projector concealed his existence, shielding him from view.

"I told you already, Grayfia. I have no interest in giving Rias the Evil Pieces now. She is still too young and hasn't reached the standards to be eligible for the Evil Pieces. So, you can tell Sirzechs that no matter how much he tries, Rias will still receive them at the qualified age. You know that I can't show any act of favoritism, even if she is my best friend's sister. And besides, I already have many problems to deal with." A male voice echoed through the laboratory, the sound of footsteps coming closer each step towards Tristan's hiding spot.

"Haaa… I know about that Ajuka. It's just that you know how much he spoiled that girl. He even ditched his duties as a Maou to spend time with her… I didn't understand why Sirzechs asked me to ask you this… Rias is still 7 years old. She is not ready to be the king of her peerage. Even if, Sirzechs said otherwise." The voice, supposedly belonging to a woman, sighed tiredly.

Right now, the two unfamiliar figures were near Tristan's hiding spot.

He held his breath, not wanting to reveal his existence to them. He didn't know who they were. Are they his mother's friends? Or are they a bad person, like that old witch?

The thoughts about the witch made his body shiver. He has difficulty breathing now. The memories of the recent events still haunted him. Her wicked laugh, her sinister smile, and those… Those purple flames will be forever etched in his mind.

Tristan strained to listen to the conversation between two strangers. His young mind grappled with the complexities of their brief discussion. The terms "Evil Pieces" and "Maou" swirled in the air, evoking a sense of intrigue. His mother always praised him for the curiosity he held for the unknown.

How ironic, he always thought that he was knowledgeable and smart. Yet, he only discovered the existence of the unthinkable moments ago.

The Purple Flames,

The supernatural,

The existence of magic, and

The identity of his mother.

These things still clouded his thoughts. Who was his mother's real identity? Why didn't she tell him about his lineage? What is the relationship between his mother and that old witch, Augusta? Where is his mother? I-Is she even alive? These questions brought a pang to his heart. The possibility of his mother being alive is pretty slim due to the conditions his mother was in the last time he saw her.

He, unconsciously, held the silver necklace circling his neck. This necklace was a gift from his mother when he was four years old. Oh, how much he wants to return to the days when he and his mother could live their lives normally. Now, his world, once filled with the warmth of a loving mother and the simplicity of childhood, burned in an instant.

As the conversation continued between the two, Tristan's curiosity overpowered his fear, and he cautiously peered from behind the projector to catch a glimpse of the speakers. The first figure, identified as Ajuka, is an attractive young man appearing in his early twenties, with light blue eyes and green hair that is slicked back. He wears a green robe that reaches his foot. He seemed to be preoccupied with various technological projects, his attention focused on the screens and devices scattered across the laboratory.

The woman named Grayfia, however, took his breath. She wore an air of sophistication. Her aura suggested authority. She is a stunningly beautiful woman appearing to be in her early twenties with back-length silver hair that features a long braid on each side with small blue bows at the end, while the rest is let down which ends in twin braids. She also has crimson eyes, like Tristan.

The two figures conversed about responsibilities, obligations, and the potential involvement of "Rias" in matters beyond her years. Tristan's young mind struggled to comprehend the significance of their words, but he sensed that these strangers held pivotal roles in a world intertwined with magic and power.

Unbeknownst to Tristan, his presence had not gone unnoticed. Grayfia's keen eyes scanned the room, and although she had not yet seen the hidden boy, she noticed the presence of an unknown individual in the laboratory. She sensed the unknown individual presence, the moment she walked into Ajuka's laboratory. Like Grayfia, The green-haired man also noticed it from the beginning.

Both of them looked at each other, nodding.

"Show yourself!" Ajuka demanded.

Tristan's immediately shrunken back to his hiding place. He panicked, not knowing what to do. Many scenarios ran through his mind, he didn't expect to be found so soon. He gulped and prepared to face the two. With his courage mustered, he stood up, revealing himself to Ajuka and Grayfia.

"A boy? A human boy, nonetheless?" Grayfia spoke. With a certain amount of shock evident in her tone. Ajuka were different. He didn't speak what was in his mind. He saw Tristan with a calculated look as if Tristan was a puzzle and he was solving it.

'A human boy? Are they not humans?' Tristan said in his mind.

"Who are you? And how did you get in here?" Ajuka asked with authority. This resulted in Tristan taking a step back, fear present on his face.

He debated himself about what he should do. Should he tell the truth about his identity? Should he tell them about the events that occurred moments ago? The event that made him separated from his mother?

'I have nothing to lose…'

"My name is Tristan, Tristan Claudius Ambrosius. As to how I got here, I still questioned myself. I don't know how I got here, the last thing I knew was that a light appeared beneath me and it engulfed me whole. The next thing I know, I am here." Tristan spoke to the adults in the room. Looking towards the expression of the two, he was surprised to see the shocked look they both had.

"Ambrosius…" Grayfia muttered. While Ajuka, seemed to be the more surprised one between the two.

"Are you Alyssa's son?" Hearing the name of his mother shocked him. He ran forward towards Ajuka and asked.

"How do you know my mother?! Where is she?! Who are you?! What is going on?!" Questions were flying towards the green-haired man. Ajuka noted that there was a desperation in his tone.

"I have a pact with your mother, Tristan. There is a pact between myself and Alyssa, a pact between a devil and a magician. Currently, I don't know the current location of your mother, it's been six years since the last time I saw her. I am Maou Beelzebub, Ajuka Beelzebub… I believe you were sent here by your mother by teleportation. Could you please tell us what happened?" Ajuka stated.

With Ajuka asking for an explanation, Tristan began to tell him about the events that occurred moments ago.

After hearing the story from the young boy, Ajuka cast a spell. A spell that could find the presence of the magician. He tried to find it several times, but all his efforts left him unrewarded. This spell should work every time, with the requirement that both he and Alyssa are alive, if one of them dies, this spell would be worthless.

Ajuka's head drops down. A tear started to drip on the cold floor, visible to the eyes of Tristan.

"A-Alyssa faced a formidable foe, Augusta of the Purple Flame. The situation became dire, and in an act of sacrifice, she teleported you here to ensure your survival." Ajuka said, with grief and pain visible in his voice.

"N-No way…" Tristan kneeled, holding his body, trying to ease the pain in his heart due to the sudden revelation regarding his mother's state. His mother had sacrificed herself to save him. His mother was dead. He gripped the necklace, clutching onto it for dear life. Tears are pouring on his face.

Grayfia winced due to the pain that was evident in the boy's crying voice.

The atmosphere was heavy with the weight of loss and uncertainty. Ajuka and Grayfia exchanged glances, silently acknowledging the tragedy that had befallen Tristan. The young boy, overwhelmed by grief and confusion, looked up with tear-streaked eyes.

'W-Why did this happen?!" Tristan's voice trembled with a mixture of pain and confusion.

Ajuka, struggling to find the right words, sighed and began to explain. He delved into the complexities of the supernatural world, the existence of magic, the existence of supernatural beings such as devils, angels, fallen angels, gods, and much more. He also explained about the pact between a devil and a magician, a pact that he shared with Tristan's mother, Alyssa Ambrosius. The revelation about Tristan being the descendant of Merlin Ambrosius, the flower mage, added another layer to the already intricate narrative.

As Ajuka spoke, Tristan's mind wrestled with the newfound knowledge. Ajuka's revelation opened a Pandora box of emotions within Tristan. The world he once knew was shattered in an instant, replaced by the intricate tapestry of the supernatural world.

"So, my mother was involved in this supernatural world all along, and I have the blood of Merlin, The Flower Mage, flowing in my veins?" Tristan muttered, his voice steadier than before. The truth brought light to him.

"Yes, your mother used to be involved. She left the supernatural world when she received a gift bestowed to her. A great blessing that could not be traded for anything else." Ajuka spoke, receiving a confused stare from Tristan.

"What do you mean?"

"Alyssa left the supernatural world when she found out she was pregnant. You're the gift that she receives. The blessing that was bestowed upon her. No matter what, you are her most precious little flower, Tristan…" Ajuka said, with a small smile adorning his face. This brought tears to Tristan. He missed his mother so much. He wanted to see her. He wanted to say that he loved her too.

He cried even harder than before, clutching his necklace as if his life depended on it.

Tristan's expression shifted, absorbing the weight of his mother's sacrifice. The guilt and sorrow mirrored in his eyes, but beneath that, a determination born within.

Grayfia, sensing Tristan's distress, approached him with a gentle expression. She extended a hand, and with a comforting touch, she reassured him, "You have our condolences, Tristan. Losing a loved one is never easy. But you are not alone. There are me and Ajuka that will help you."

Tristan, still grappling with the pain of loss, looked up to Grayfia. A mix of emotions played across his face – grief, confusion, and a hint of determination. He wiped away his tears, took a deep breath, and nodded to her.

"Augusta… She was after me and my mother, right? What makes me so special?" Tristan's voice trembled with a mixture of fear and curiosity.

Ajuka exchanged a somber glance with Grayfia before continuing, "Your lineage is unique, Tristan. You have the most potential to be the strongest mage out there. Many factors led the descendant of Merlin to be so feared. You are a descendant of one of the most revered magus in history. This is only a speculation, but I think that Augusta tried to kill you to prevent you from being a magus that could jeopardize her plans."

As the layers of his identity unfolded, Tristan's mind became a battlefield between grief and newfound purpose. The realization that his mother had kept the supernatural world hidden from him became a haunting truth, but it also fueled a desire to understand his heritage and seek justice for his mother's sacrifice.

"I won't let Augusta get away with this. I'll find her and I'll kill her for what she did. I swear by my name!" Tristan declared, his eyes reflecting a determination that surprised even Ajuka.

Grayfia, silently observing, nodded in acknowledgment. She saw glimpses of the strength within Tristan – the strength to confront the harsh realities of the supernatural world. But one thing is for sure, Grayfia believes that the future of Tristan Claudius Ambrosius will be interesting.

Ajuka sighed, understanding the gravity of the situation. "Tristan, you are still young, and the path ahead is perilous. But if you choose to tread it, know that you won't be alone. I will assist you in unlocking the potential within you, and together, we may uncover the truth behind Augusta's motives."

"Thank you…" He whispered, acknowledging the support from them. The tales ahead were unknown, but Tristan, with newfound strength, vowed to have his revenge.

And so, the tale of Tristan Claudius Ambrosius unfolded – a tale of a boy who emerged from the ashes of tragedy to embrace his destiny in a world where the supernatural, magic, and mystery collided.
