Extra Demon: Sacred Academy of Light

"Why are you running, damn coward!" Leslie exclaimed angrily, looking around. In her hand was a large, slender sword, almost as big as her body, surrounded by yellow lightning. She walked with a scowl, scanning her surroundings, only to find grass with some roses of various colors. It was a meadow, the place where she was supposed to fight the demon—or so she thought. "Why are you hiding! Aren't you supposed to be a man?" She was beyond irritated, having spent four hours chasing the damned demon who kept running from her.

The demon was about the size of a child, no taller than 1.45 meters, but had a deep voice and a proud demeanor. The wretch even dared to look at her with disgust, which led her to cut off one of his arms. After that, he somehow managed to escape her sight and hadn't reappeared, leaving her frustrated after four hours of searching since their initial encounter.

Looking around, she sensed something strange. She clearly felt the demon's presence close by, but at the same time, it seemed far away. Because of this, she never dared to lower her guard, though her patience was wearing thin. Closing her eyes, she took a deep breath. A moment ago, she had an idea that might eliminate the feeling of being followed, but the problem was... "I'll hurt myself too..." she thought to herself. The skill was basically... an explosion. A complete madness—an explosion of lightning around her. She had practiced this skill specifically for this event. What she had previously been doing was imbuing her sword with lightning, as well as her whole body, which was too easy; she managed it in under an hour. It left her unsatisfied, leading her to attempt something else.

She even unlocked a new skill:

[Blazing Explosion]

[Description: A powerful and destructive skill that combines the speed and power of lightning with the force of an explosion, generating a quick, bright burst of electric energy that extends in a significant radius.]

Looking at her newly created skill...

"What are you doing here?" The Seraphim's voice resounded behind her. Leslie turned toward her, frowning. "Looking at my skill?" She tilted her head a little. Wasn't it obvious? It's easy for someone to see the skill they generate and create on their own; you just enter your soul, and you'll see it clearly.

"Hmmm... I see, nice skill... I suppose. But," the Seraphim said with a proud smile, "my skill is much more powerful!" She shook her head. "You don't have the maximum control over lightning; you're still at the most basic level."

"Yeah, yeah, whatever you say. Let me think for a moment..." Leslie waved her hand dismissively. She knew that what the Seraphim said was true. After all, yellow lightning is the most basic, and she's still not able to wield the red lightning.

"Having trouble with that little demon?" she asked with a slight smile. Leslie glanced at her from the corner of her eye and nodded. "It's a bit confusing."

"I see... well..." The Seraphim gave an awkward smile and looked to the side. "Actually, he's been behind you the whole time. He transformed into a fly and has been following you for the past four hours. For some reason, he can't attack you, but I guess that's the limit of his transformation."

"..."

"Kid... you have a peculiar scent," the man in front of him said with a hoarse voice. His eyes couldn't be seen as they were covered by a hat. The man was nearly two meters tall, thin, dressed in a black suit with some bloodstains, a red tie around his neck, and white gloves on his hands. The demon stood calmly in the middle of the forest. The skies were gray, silently weeping, and the ground was dirt, forming mud beneath them. In the demon's right hand was a scythe as tall as his body, made of gleaming black stone. The demon looked forward with bright eyes. The young man, in particular—black hair, blue eyes—had something strange about him, something very familiar yet distant. Blood calls to blood, but...

Arthur took a deep breath, his eyes also fixed on the demon in front of him. He could feel it—the demon was of a lower rank, clearly, but his aura and presence told a different story. He seemed like a mid-level demon, or so it seemed from his attacks. Looking at the superficial cuts on his chest, it was clear he wasn't the only one wounded. "Too difficult," he thought to himself, gripping the blue flame chains in his hands tightly. He was nervous, unable to calm his racing heart, trying to suppress his anxiety. The demon in front of him... was no ordinary creature, by any means. He wasn't a nobody; just by his attire alone, it was evident. This demon was a follower of the Sin of Wrath.

The Sin of Wrath is well-known for its followers dressing as elegantly as possible, in black suits. Every one of them who has sworn loyalty has the obligation to dress in black suits. And this demon before him... Alisar, the Patient, is one of them. Although his power is low, when he uses his demonic transformation, he rises to a mid-level. At his peak, he could match a high-level demon...

"I can't believe it!" he cursed in his mind. At first, he had only minor suspicions, unclear. But... looking again at the scythe in his hand, especially the hand holding it... there was the symbol of the Sin of Wrath. A circle made with needle-like shapes around it, and on one of them, a small red drawing of a dog with its mouth open, so small it was hard to see clearly...

BOOOOMMMMM!!!

The earth shook violently... Raising his gaze quickly, the gray sky had turned a blazing red... Flames shot up into the sky as if trying to pierce the world itself. These flames formed a mushroom cloud, as if a nuclear bomb had just been dropped on the world. Even the cold rain evaporated completely, and a hot wind swept through everything around them...

Looking with sad eyes... "It's awakened... The Seraph of the End... has descended."
