The Limitless Curse (Rewrite taking over the original story)

Third-Person POV

The Underworld remained shrouded in an eerie silence, its usual vibrancy replaced by uncertainty. The Gremory estate's halls felt colder than usual as Rias' peerage gathered in the study, each member deep in thought. The recent power outage and Grayfia's warning weighed heavily on everyone.

Akeno leaned against the wall, her arms crossed. "It's strange, isn't it? The blackout wasn't caused by any natural phenomenon. Someone—or something—is pulling the strings."

Kiba nodded. "And they're careful. We've found no traces of magic, no evidence of their presence. Whoever is behind this knows what they're doing."

"Which makes them dangerous," Rias added, her tone grim. Her blue eyes flicked toward Y/n, who stood by the window, gazing out into the darkened landscape. "What do you think, Y/n? You're unusually quiet."

Y/n smirked without turning around. "Quiet's good. It means I'm thinking." He finally glanced back at the group. "Whoever's behind this is smart. They've masked their tracks so well that even devils like you can't pick up on their trail. That tells me they're operating on a level beyond what you're used to."

Issei, who had been unusually silent, blurted out, "So, what do we do? Just sit around and wait for them to attack again?"

"Hardly," Y/n replied. "We go hunting."

Scene Change: The Forest

The group ventured into the darkened forest beyond the Gremory estate, their footsteps cautious. Koneko walked beside Y/n, her sharp senses alert for any sign of danger.

"Are you sure this is the right way?" Issei asked nervously, his gaze darting between the shadowed trees.

Y/n smirked. "Not really. But it's better than sitting around doing nothing."

Suddenly, the air grew colder, and an unnatural mist began to creep through the trees. Rias raised her hand, summoning a small orb of demonic light to illuminate their surroundings.

"This mist..." Akeno murmured, her brows furrowing. "It's not normal. There's magic in it."

Kiba drew his sword, his eyes scanning the forest. "We're not alone."

Before anyone could react, a low chuckle echoed through the mist. The sound was chilling, carrying an edge of malevolence.

"Well, well. Look at you all, stumbling around in the dark like lost children."

A figure emerged from the shadows, their silhouette barely visible through the mist. They wore a hooded cloak similar to the ones the cloaked figures had donned, but their aura was different—chaotic and unpredictable.

Y/n's crimson eyes narrowed. "Who are you?"

The figure laughed again, their voice dripping with amusement. "Let's just say I'm a friend of someone very powerful. And I've been sent to... test your worth."

Before anyone could respond, the figure raised their hand, and the mist thickened, wrapping around the group like an oppressive shroud. The world seemed to dissolve, leaving each member isolated, trapped within their own minds.

Rias' Vision

Rias stood in the grand halls of the Gremory estate, the familiar warmth of her family home turned cold and desolate. The windows were shattered, the tapestries burned, and the air reeked of ash.

At the far end of the hall, she saw her brother, Sirzechs, lying lifeless on the floor, his once-glorious aura extinguished. Around him, her peerage lay scattered, their bodies broken.
