The room was silent except for the faint, rhythmic dripping of water from the cracked ceiling. The damp air clung to your skin, the dim lighting casting long, ominous shadows across the stone walls. In the center of the room, Mahito hung suspended by cursed bindings, his body contorted in an unnatural position. The ropes glowed faintly with cursed energy, their intricate seals pulsing as if alive.

Despite his battered appearance—cuts oozing blackened blood, one eye swollen shut, and his face marred by your handiwork—he still managed a smirk.

"Such determination," he rasped, his voice rough but laced with mockery. "You've gone through so much trouble, and for what? To play jailer to a curse? You're wasting your time."

You stepped closer, the soles of your boots crunching against shards of what used to be Mahito's own malformed creations. His arrogance, even in the face of defeat, didn't faze you. If anything, it fueled the fire burning within you.

"Wasting my time?" you echoed, tilting your head slightly as you stopped just a few feet from him. "Oh, Mahito. Time is something I have plenty of. And for you..." You crouched so you were at eye level. "For you, I'll make sure every second feels like an eternity."

His grin faltered for a split second, but he quickly recovered. "You think you're the first person to try and break me? Pain doesn't scare me."

A soft chuckle escaped your lips, and the sound sent a shiver through even the corrupted air of the room. "I'm not trying to scare you," you said, your tone disturbingly calm. "I'm just here to make you understand."

Before he could retort, you raised your hand, your cursed energy flaring to life. It crackled like lightning, the sheer force of it making the room tremble. Mahito's smirk vanished as your hand hovered over his chest.

"Don't—"

You pressed your palm against him, and his words dissolved into a howl of pure agony. The energy seeped into him, not attacking his body but his very soul—the core of his existence.

His body convulsed, flickering between forms as he tried to stabilize himself. The usual confidence in his voice was gone, replaced by desperate gasps as he struggled to speak.

"What... what are you—"

"Something you're very familiar with," you interrupted, your voice cold. "Dismantling the soul. Piece by piece. But unlike you, I'm not doing this to kill. No, Mahito. You don't get that mercy."

You twisted your hand slightly, and he let out another scream. His form flickered again, the sound of his suffering reverberating off the walls. You didn't flinch; you didn't falter. You were in control now.

"I've seen what you've done," you said, pulling your hand back momentarily. "The lives you've destroyed, the people you've warped into monsters. I've heard their screams. And now... now you get to hear your own."

Mahito slumped as much as his bindings allowed, his chest heaving as he struggled to recover. He looked up at you with one half-lidded eye, his smirk replaced by a grimace.

"You think this makes you better than me?" he spat, his voice shaking. "You're just like me—a monster who takes pleasure in pain."

You leaned in close, your face mere inches from his. "The difference," you said softly, "is that I'm doing this to protect others. You did it for sport."

Mahito's laughter was weak, but it persisted. "Protect others? Don't make me laugh. You're delusional if you think this will change anything. The world is full of curses like me. Even if I die—"

"You're not going to die," you interrupted, your voice cutting through his like a blade. "That's the beauty of it, Mahito. You'll live. For centuries, maybe longer. I'll make sure of it."

His breath hitched, a flicker of genuine fear crossing his face. You straightened, walking over to a nearby table lined with cursed tools. Each one glimmered menacingly in the dim light. You picked up a thin, jagged knife, its edge radiating with cursed energy, and turned back to him.

"You're right," you continued, running the blade along your palm as if testing its sharpness. "The world is full of curses like you. But you? You're special. You're the first one who's going to experience what it's like to be the hunted. To be powerless."

He snarled, thrashing against the bindings, but they held firm. The seals glowed brighter in response to his struggles, tightening around him.

"I'll get out of this," he growled, though the fear in his voice betrayed his words. "Someone will find me. Someone will set me free!"

You smirked, stepping closer with the blade in hand. "Let them come. I'd love the company."

The first cut was shallow but deliberate, and the room was once again filled with Mahito's screams. You worked methodically, each slice precise and calculated. The cursed tools weren't meant to destroy him; they were meant to prolong his suffering, to ensure he felt every ounce of pain without the release of death.

Hours turned into days, and days into weeks. The once-proud curse who had tormented so many now found himself on the receiving end of endless torment. Every attempt to manipulate his soul was met with another wave of agony as the seals tightened their grip, ensuring he couldn't escape.

In the moments of quiet between his screams, you would sit across from him, watching as he tried and failed to regain his composure.

"You'll break eventually," you said one day, your voice devoid of emotion. "And when you do, I'll rebuild you just enough to start again."

Mahito didn't respond. His head hung low, his body trembling. The spark of defiance that once burned in his eyes was now a faint flicker, barely holding on.

And yet, you knew he wouldn't die. Not unless you allowed it.

You turned and left the room, the heavy door slamming shut behind you. Outside, the seals on the door glowed brightly, ensuring no one could enter—or leave.

Mahito was alone, left to endure the torment you'd crafted for him. For the rest of his existence, he would be a prisoner to your wrath, a twisted reflection of the pain he'd inflicted on so many others.

And for you, that was enough.
