DxD: Lost in Time

A young woman stood amidst a devastated forest, her sharp, piercing gaze locked onto a massive white creature with a hole in the centre of it's chest, thrashing within a containment field.

The glowing sigils of her summoned magic circles pulsed with power, faintly illuminating the scarred earth. Her long black hair cascaded to her waist, its silken strands shifting slightly with the wind.

Her attire, a high-collared battle dress woven with enchantments, reflected her position as a battle-hardened warrior, its dark fabric trimmed with silver.

The creature she restrained was monstrous, standing nearly twelve feet tall. Its wings, leathery and jagged like those of a bat, flapped violently against the restraints, sending shockwaves through the surrounding air.

A bone-white mask shaped like a grotesque skull covered its face, its sharp, menacing teeth grinning through the dark.

The hollow pits of its eyes glowed with a hellish red light. Its roars reverberated through the barrier, shaking the air like thunder, forcing the woman to hold her ground firmly.

"A Mid-High Class...and it's still growing stronger," muttered Serafall, her voice a mixture of disbelief and grim resolve.

"What kind of child possesses such unrelenting killing intent?" Her violet eyes narrowed as she surveyed the beast, sensing the malice radiating from it.

An aura steeped in years of war and slaughter, utterly unbefitting someone so young.

The ground beneath her cracked, the remnants of trees reduced to splinters from the sheer pressure of its presence.

Suddenly, the beast halted. Its chaotic aura vanished, leaving a deafening silence.

CRACK! CRACK! CRACK!

Fissures formed across the white armor covering its body. Shards of ivory-like material fell to the ground, revealing the silhouette of a boy hidden beneath.

The woman watched intently. As the final pieces of the beast's armor shattered, a faint figure emerged.

A young boy, barely in his teens. His face was obscured by strands of messy blonde hair. For a brief moment, he seemed human, fragile and almost pitiable.

But that moment passed.

The boy's head lifted, revealing eyes burning red, the sclera around them pitch black. An unholy energy erupted from his body, the crimson glow tinged with an almost sentient malice, a manic smile plastered on his face.

'Is that truly Hisashi?' Serafall's breath caught in her throat as she beheld the boy before her. The warmth and earnestness she had seen in him earlier were gone, replaced by an overwhelming aura of malice.

His eyes burned with a crimson intensity that seemed to pierce through her, their once-human light eclipsed by unrelenting rage. This was no longer the boy who had smiled shyly just hours ago. No—this was something far darker and sinister.

"RAAAAAAAH!"

A cataclysmic shockwave blasted outward, throwing dirt, shattered rock, and chunks of debris into the air. The earth trembled beneath the force. Serafall instinctively leaped back, her feet skidding across the fractured ground.

"This power...it's uncontrollable," she muttered under her breath, her gaze unwavering.

The boy's aura darkened further, coalescing into a fluid, bone-like substance. It crawled across the right side of his face, hardening into a jagged mask.

The mask bore the same malevolent grin as the creature he had been moments before, its broken edges flaring upward like a crown. [A/N: Ichigo's hollow mask but with a red Crescent Moon on his right eye.]

In his hand, a weapon materialized. A katana forged of black crystal, its surface flickering with ghostly red energy.

A wicked grin split his face.

"Finally... I am free baby! Feels good." he whispered, his voice echoing unnaturally. His laughter soon followed–cold, wild, and utterly devoid of humanity.

The air thickened with tension, and then, chaos.

He vanished.

SWISH!

A fountain of blood sprayed into the air as he reappeared behind a devil soldier, the katana slicing clean through the soldier's armor.

ZOOM! ZOOM! SWISH!

Each sound signaled another life taken, another body falling to the ground. His movements were blindingly fast, a blur of red and black weaving through the battlefield like a phantom of death.

"Shit! Retreat—ARGH!"

One of the commanders tried to shout an order but was silenced as the boy's hand punched through his chest. The boy grinned, his hand soaked in crimson.

"When was the last time I had this much fun? A decade...?" His voice rang out, sharp and mocking.

The battlefield was a sea of blood, the remaining devils retreating in a panic. But he wouldn't allow it.

With a flick of his wrist, a ball of condensed red energy formed in his hand.

One devil, desperate to save himself, tried to escape. But the boy appeared before him in an instant, driving his blade into the devil's chest.

"So, you were willing to abandon your comrades. Understandable but cruel, even

by my standards," the boy said, his voice dripping with mockery. "Any last words?"

"You–"

"Cero," he intoned.

A massive explosion ripped through the area. Trees were uprooted, and the ground cracked under the force. Serafall shielded herself from the devastating blast, her eyes narrowing.

*This child… he's dangerous.*

She considered intervening, perhaps even taking him under her wing for the upcoming war. But she hesitated.

'He still needs to grow,' she thought.

The boy turned his attention to her, the mask and katana radiating power. "Who are you?" he demanded.

"Who I am does not concern you. I'm just a monster who currently owns this body."

"Where is Hisashi?" Serafall asked cautiously.

"Recovering," the boy replied nonchalantly.

"If you want to see him so badly, fine. Nothing fun is going on anyway."

**Hisashi's POV**

My consciousness stirred, an oppressive weight pressing against my mind.

Flashes of the battle earlier surged through my thoughts like a storm. Chaos,destruction, and a cold, wicked laughter that wasn't my own.

I groaned, my body feeling heavy, as though it were submerged in a viscous liquid. Slowly, I opened my eyes.

The first thing I noticed was the warm purple glow of light streaming through a window. The air carried the faint scent of lavender, calming yet unfamiliar.

I sat up abruptly, my instincts flaring to life. My surroundings were unfamiliar. A room furnished with dark wood and royal blue curtains.

The bed beneath me was soft, far too soft for someone who had just waged a battle.

*Where the hell am I?*

Memories of the fight clawed at the edge of my mind, the vivid image of that monstrous mask forming over my face. The weight of the katana in my hand, the crimson Ki radiating with every attack... it all came rushing back.

My chest tightened as I clenched my fists, the power I had wielded still faintly humming

within me.

'I lost control again. Dammit.'

My senses heightened. I could feel several presences outside the room, their

energies sharp and focused. Surrounding me, no doubt.

*Hostiles? No… observers.*

Grinding my teeth, I threw the covers off and swung my legs over the edge of the

bed. My feet met the cold wooden floor as I rose to my full height. My muscles

were stiff, but my instincts were sharp.

In a single motion, I dashed toward the door, wrenching it open with a controlled but forceful grip. My hand shot out, wrapping around the neck of the first figure

standing in my path.

"Don't move," I growled, my voice low and threatening.

The woman I held stiffened but didn't resist. Her fiery orange hair was tied into a

neat bun, her piercing blue eyes wide but calm despite my grip.

She wore a traditional French maid's uniform, the pristine fabric clashing with the chaos of the situation.

"Who are you? Where am I?" My grip tightened slightly, though I was careful not

to harm her.

Her voice was steady, betraying no fear. "My lord, you are in Sitri territory. Lady

Serafall brought you here after you collapsed during your battle."

"Sitri territory?" I echoed, confusion and unease settling in. Her words unlocked a torrent of memories—the battle, the devil soldiers, the hollow's laugh echoing in my head.

The hollow.

The mask.

That destructive power.

My breathing quickened, panic threatening to overtake me. I forced myself to focus, releasing the woman and stepping back.

"Battle…" I muttered, my mind racing to piece everything together.

*I used the hollow mask. I… let him take control. He had full reign over my body, and I couldn't stop him.*

Forcing the memories to the back of my mind, I turned to the maid. "Where is Serafall?"

"Lady Serafall is currently attending to matters outside. She asked me to inform her the moment you woke." She bowed slightly, her calm demeanor unnerving.

I took a deep breath, running a hand through my hair. The situation was dire, and I had no time for pleasantries. "Fine. Take me to her."

The woman nodded, stepping aside to guide me. But as I followed her, my thoughts were elsewhere.

'I've temporarily lost authority over my own body.'

'This is my fault. I need to become stronger. Strong enough to crush him. Strong enough to never lose control again.'
