Kael stood at the edge of the city, his crimson eyes scanning the vast, empty plains beyond. The stillness of the summer evening was a stark contrast to the storm brewing within him. He had sensed it for weeks—someone, or something, was watching him. A disturbance in the threads of his carefully constructed anonymity had finally been confirmed.
A figure approached from behind, breaking the silence. It was Rias Gremory, her face a mask of worry.
"Kael," she began, her voice softer than usual, "I don't know what you've done, but the Underworld is stirring. There's been talk of... an old family, one with claims of vengeance. They're looking for someone, and I think it's you."
Kael's jaw tightened, but he gave no immediate response. He had been avoiding confrontation for years now, keeping his devilish origins and power hidden. Yet, the truth was always lurking beneath the surface.
"I've handled it before, and I'll handle it again," Kael finally replied, his tone calm but resolute.
Rias hesitated, clearly wanting to press him further, but she nodded. "Just... be careful. Whatever they're planning, it feels personal."
Kael gave her a slight smile, his usual façade of calm back in place. "Always."
The attack came three nights later, swift and brutal.
Kael was alone in his small home, deep in the process of refining the wards and cloaking spells he had placed around the property. His paranoia had served him well; the moment the intruders breached his perimeter, he felt it.
He stood and turned toward the door, his devilish aura rising as his eyes glowed faintly. The air thickened with malice as several figures appeared in the shadows. They wore the crest of the Drakos family—a family Kael had thought long eradicated.
"So, the prodigal son hides among humans," one of them sneered, stepping forward. His voice dripped with venom, and his aura matched Kael's in intensity, though it lacked the refined control Kael wielded. "Did you really think you could escape the blood debt?"
Kael sighed, his crimson eyes flickering to a darker hue. "I didn't escape. I erased it. But it seems some people just don't know when to let go."
The leader of the group laughed, a low, guttural sound. "Arrogant until the end, just like your father. But don't worry—you'll join him soon enough."
Kael didn't respond. Instead, he raised a hand, and the air around him warped. His power, long restrained, began to leak into the room. The shadows twisted, forming shapes that seemed almost alive.
"You came here to kill me," Kael said, his voice steady but cold. "You should have come prepared to die instead."
The battle that ensued was nothing short of chaos. Kael's power, suppressed for years, erupted like a dam breaking under pressure. His assailants came at him with everything they had—spells that tore through walls, weapons imbued with infernal power—but it wasn't enough.
Kael moved like a phantom, his control over darkness and flame unparalleled. Shadows coiled around his enemies, dragging them into the void, while bursts of crimson fire scorched the air. His movements were precise, calculated, and devastating.
One by one, the Drakos family fell. Their screams echoed through the night as Kael unleashed the full extent of his abilities. By the time the dust settled, the house was in ruins, and the once-proud warriors of the Drakos family were no more.
The next day, Kael stood in the ruins of his home, surveying the damage. The fight had been necessary, but it had also been a revelation. He couldn't stay hidden forever.
As he prepared to leave, he was interrupted by a familiar presence.
"Kael."
He turned to see Himejima Akeno standing at the edge of the wreckage. Her expression was a mix of curiosity and concern.
"You've been busy," she remarked, her eyes flicking to the scorched earth and shattered walls.
Kael didn't respond immediately. Instead, he turned back to the ruins, his hands in his pockets. "I suppose you're here to tell me I can't stay."
Akeno shook her head. "That's not my decision to make. But I wanted to know... Why? Why go to such lengths to hide what you are?"
Kael finally met her gaze, his expression unreadable. "Because sometimes, survival means erasing who you are. But that doesn't mean you forget."
Akeno studied him for a moment, then nodded. "So what now?"
Kael looked toward the city, a faint smile on his lips. "I'll find another way. But not here."
Kael didn't leave immediately. Instead, he spent the next few days tying up loose ends. He met with Rias and Sona, explaining his departure in vague terms.
"It's for the best," he told them, his tone firm. "I've stayed here too long already."
Rias frowned but didn't press him. "Just promise me one thing, Kael. Don't disappear entirely. If you ever need help... you know where to find us."
Kael nodded, appreciating the sentiment but knowing he'd likely never take her up on the offer.
In the hidden corners of the city, Kael found a small, unassuming shop for sale. It was tucked away in an alley, far from the bustling streets. Perfect.
Over the next few weeks, he transformed the space into something uniquely his. The shop, simple and unremarkable on the outside, became a sanctuary. Inside, it was a blend of human and devil aesthetics—a reflection of the duality Kael had come to accept.
He opened quietly, catering to the odd customer who happened to stumble upon the place. It was a far cry from the life he had once lived, but it was peaceful.
And for now, peace was enough.
