Darkness Breathing Demon Slayer Novels & Stories

My heart is pounding but I can already hear his heavy breathing, he’s fallen asleep. But he’s left me feeling like a mess of nerves. Goddess… I can feel his inner turmoil, feel the lingering darkness at the cusp of his aura as if waiting for the right moment to poison him. I shudder and close my eyes, taking deep steadying breaths, letting my aura swirl around us, repelling the darkness. But what will happen when I fall asleep? His mind is in turmoil… the darkness is relishing in it…

“We need to train you more, Isadora. Things are going to get worse before they get better.” Silas inclines his head, the movement smooth as falling dusk. “You’ve felt it too. The pressure.” My throat is dry, but I nod. Silas begins. Shadow-work. His voice is low as midnight tide. “Breathe. Don’t fear the dark; invite it. It will answer.” I draw in air that tastes of iron rain. Close my eyes. The darkness inside me stirs, velvet and cold. A curl of shadow leaks from my palms, alive.

The room begins to fill with darkness, all candles fizzling out. “From a book. Azazel sound familiar to you?” No more whispering. The entire room is filled with cowering fear. “You are playing with my patients little girl.” The darkness begins to engulf people as well, absorbing their screams of terror. “Good.” The wind behind me sweeps the darkness from my feet. “Because your time is also running out.” The Daemonium growls at me and a new wave of darkness attempts to crash over me but the wind forms a swirling vortex around me.

Now, when I looked into it, I saw only stars. I knelt beside the water and whispered, “It’s over.” The reflection rippled once—just once—and then stilled. I knew he could still see us through the world, but he couldn’t touch us. Not through dreams. Not through fear. Damon’s mind was his own now. The next morning, Lucas found us in the garden. Damon was practicing his breathing again, golden sparks flickering gently from his hands without burning the grass. “He’s in control,” Lucas said quietly, awe threading through his usually stern tone.

Exposed. Dante stepped into the sliver of neon light. His skin was translucent, showing the pulsing gears of a machine beneath the muscle. He pushed her back onto the bed. The weight of him hit her like a falling mountain. It was a 3D pressure that crushed the air from her lungs, grounding her in a reality that was falling apart. "Am I the demon, B?" he whispered, his teeth grazing the shell of her ear. "Or am I the only thing keeping you from drifting away?"

The Darkness he respected moved on its own! Darkness vanished within the shadows. And he reappeared in front of this white-haired animal. "Echolocation!" Darkness used his howl. *bam! The two powers collided yet... It was a tie! The Hells Breath was blocked equally. Of course, that was Darkness! Butt! God of Night! Darkness Butt! Of course, Butt didn't use his all in that attack, if he did then this Demon King would really die. Their enemy is the Demon King who uses Hell's Breath!

The demon turned his head with a scowl when his left eye twitched, “What the heck is this now…?” A blinding light burned the night as if it was day. All eyes watched in awe as the demon's shadow was consumed by the light. The demon narrowed his eyes with annoyance and raised his hand to summon his shadow. ‘THUMP! THAP! THWACK!’ They both fell on the debris a second later. Laylin's eyes were fixed on the moon and then fell on her husband's trembling body but the demon was too enraged as he flailed about trying to summon his shadow in vain

Energy whips through me, crackling over my skin and churning my blood as I chant silently into the night. “What…?” Amos gasps. His hands loosen around my neck. Greedily sucking in the heavy night air, I take the opportunity to speak the incantation aloud. The syllables slide out in a coarse whisper, echoing across the water in terse ripples. “​​From light to shadow, from stone to bone, I send you back to the void you’ve known. By earth, by sky, by sea, I proclaim, Be gone, demon, in darkness remain.”

"Look at me. You've learned control, you can teach him. I know you can." His voice cut through the panic trying to climb up my throat. I focused on him, on the steady way he was breathing, on the absolute certainty in his eyes that I could do this. The wild thing inside me that wanted to burn and rage and destroy slowly quieted. I turned back to Dante. "Follow my breathing. In and out, just like that. Feel the power but don't fight it. It's part of you now." He stared at me for a long second then matched his breathing to mine. In. Out. In. Out. The silver glow leaking from his hands started to dim. The fire that was crackling around us receded inch by inch until it finally disappeared comple

Darkness spilled from him, thick and writhing, wrapping around his body like smoke searching for form. “I am a god!” he roared. “I am Erebus the demon of darkness!” The sword left my hand. Not hurled. Released. It cut through the air with ruthless precision and struck his chest. His scream split the space, raw and inhuman, echoing until the walls trembled beneath it. Then nothing. The darkness tore away like it had never existed. His body hit the floor. Kael lay there still, human, broken. The power vanished as quickly as it had come. My legs gave out, and I collapsed, the breath torn from my lungs as weakness flooded in.
