My own blood. Charon's demonic blood, offered to push my energy beyond the limits of sanity, sprayed from the nerve endings in my arms and head. The hot liquid blistered upon contact with the vacuum air of the shrine clearing, creating a thick, reddish steam. I no longer felt human; I felt like a killing machine in the middle of a total overheat.
The sound of my blades clashing was no longer just a roar. It was a resonance. The vibration was so powerful that the ground beneath my feet cracked, and the bamboo trees at the edge of the clearing began to shake violently. This noise was no longer a pure sound wave; it was a physical manifestation of rage and the life-and-death contract between myself and Charon.
In front of me, the Demon of Silence stood tall. Its body, half-frozen by its own black fluid, began to evolve. The thousands of white ribbons that had previously formed rotted wings now compressed, merging into a single giant spear blade ten meters long. The red mantras atop the ribbons glowed brightly, pulsing to the rhythm of the demon's invisible heart.
"Woi, Aqua! You idiot! Don't charge in alone, you fool!"
That voice belonged to Kageyama. I could see him out of the corner of my eye. He stood gasping for air, clutching his greatsword with trembling hands. His face was deathly pale, but his gaze showed not a shred of doubt. Beside him, Natsu was hunkered down, clutching her chest as it rose and fell rapidly. She looked exhausted, having spent too much blood to fend off the demonic minions earlier.
"Hey, Grumpy Senpai! It's moving toward us!" I shouted.
The Demon of Silence attacked. The ribbon spear lunged with a speed that surpassed visual perception. However, in my eyes—now glowing a deep, solid yellow—the movement looked slow. Not because the spear was slow, but because my demonic resonance accelerated my perception of reality.
CRAAAAASSSSHHH!
I slammed the spine of my blade directly into the tip of that massive ribbon spear. The impact didn't produce an explosion, but rather a painful, high-frequency static. Superheated sparks sprayed in every direction. The heat was so extreme that the stones of the ruined shrine began to melt into magma beneath my feet.
"Damn... so heavy!" I growled. My right arm began to creak. The pressure from the spear felt like it wanted to bury me alive into the Earth's core.
"I won't let you die before you pay back your debt to me, Aqua!" Kageyama roared. He reached into his pocket and threw something at the feet of the Demon of Silence. "Summon. Sanbi!"
Sanbi. The Three-Tails. Kageyama's contracted demon lunged into the silence between us.
The head of a giant wolf demon emerged from the darkness, but this time it didn't attack directly. It simply clamped its jaws onto the ground beneath the enemy, causing the Demon of Silence's balance to falter for a split second.
"Now, Natsu!" Kageyama commanded.
Natsu stood up with her signature wild smirk, despite the blood trickling from her nose. "Hah! Watch closely, you low-life demon! Behold the power of nobility!"
Natsu slammed her hand onto the ground. The blood that had sprayed from my wounds and Kageyama's was not allowed to go to waste. The crimson liquid moved like snakes, crawling rapidly across the earth, then suddenly froze into pillars of crystal thorns that locked the Demon of Silence's legs in place.
"Aqua! Use my blood on your blades! Burn it all!" Natsu screamed.
I understood. I pushed my speed to the absolute maximum. Natsu's blood coating my blades began to boil, creating an unstable yet highly destructive aura vortex. The giant ribbon spear began to crack. The red mantras upon it faded, scorched by the heat of the resonance.
"JUST DIE ALREADY, YOU BASTARD!" I screamed, channeling every remaining memory of Charon into my swords.
With one brutal jerk, I cleaved the giant ribbon spear in two. The force of my slash was so immense that the Demon of Silence was blown backward, crashing into the walls of the ruined shrine.
Now, my path to the old peach tree behind the shrine was wide open. The small bell buried in its roots—the heart of this silence—vibrated faster and faster.
"Hurry, Aqua! Before it rises again!" Kageyama warned. He coughed up blood, his body reaching its limit from summoning too many subordinates in a single night.
I leaped. The wind whipped against my face, carrying the scent of iron and death. But just as I was about to touch the bell, the Demon of Silence did something unexpected. It no longer used physical force. It released all the silence it had stored for thousands of years in one single psychological shockwave.
Silence.
My world suddenly went empty. Not just sound was gone, but sight, smell, and touch. I couldn't feel the air on my arms. I couldn't feel the ground beneath my feet. I couldn't even feel the presence of Kageyama and Natsu behind me.
Aqua-kun...
Sumeragi's voice sounded incredibly distant, like a star in another galaxy.
This is true emptiness, the Demon of Silence whispered inside my mind. Here, nothing is real. Everything you see is fake. Everything you feel is a lie. There is only you, and nothingness.
I felt myself starting to dissolve. My memories of breakfast with Kageyama, of stupid arguments with Natsu over the last piece of meat—all of it began to fade into a blinding white.
"Am I... dead?" I thought.
Then, in the midst of that void, I heard something impossible. Not a sound, but a vibration.
Thump... thump... thump...
It was the sound of a heart. But not mine. It was Charon's heartbeat resonating with the heartbeats of Kageyama and Natsu. Even though my world was silent, I could feel their presence through the blood bond we had just shared on the battlefield. Natsu's blood, still flowing on my twin blades, provided a "warmth" that refused to be erased by the silence.
"Damn it..." I muttered internally. "You two are really noisy, aren't you?"
I could feel Kageyama's invisible hand pushing my back. I could feel Natsu's laughter mocking me for being weak. This silence was nothing compared to the noise of the life I lived with them.
"Sorry, but... I WILL NEVER BE ALONE!"
I screamed. A scream that shattered the demon's psychological vacuum. The sensation of the swords in my arms returned with a surge of agonizing pain, but I welcomed it because it meant I was still alive.
I swung my blood-crystal blades downward, straight at the small bell in the tree's roots.
CRASH!
The bell shattered into a thousand pieces.
Instantly, the "dam" of silence holding back the world collapsed. The sound of the bamboo forest returned with full force. The sound of the night wind returned. And most importantly, the sound of my roar thundered across every corner of Kyoto.
The Demon of Silence exploded, its body disintegrating into black ash that drifted away on the night breeze.
I stood in the ruins, my body smoking. My demonic energy slowly receded back into my skin, leaving behind scars that were still hot to the touch. I panted, feeling my heart beat in sync with the lingering energy around me.
"Aqua... good job, you moron." Kageyama walked over, his steps unsteady. He leaned his body against the now-withered peach tree.
"Of course he succeeded! Didn't I tell you? It's because I'm the one who gave him the stage!" Natsu arrived, wiping her nose, though her face looked immensely relieved. She tried to punch my shoulder but almost fell over herself from weakness.
I looked at the two of them. Kageyama, who was always stiff, and Natsu, who was always selfish. We were a strange, broken team, and we probably wouldn't last long in this crazy world. But tonight, under the bleeding Kyoto sky, we were the only real thing.
"Kageyama, Natsu..." I called out softly.
"What?" they asked in unison.
"I'm hungry. Let's go home and eat something good."
Kageyama let out a long sigh, a rare, faint smile appearing on his face. "Yeah. Let's go home."
Above us, a black crow watched for a moment before flying toward the horizon. This physical battle might be over, but I knew the chains binding us, whether from Sumeragi or from fate, had just been pulled tighter. We survived today, but the world was still thirsty for our blood.
Well... as long as there's spicy curry and those two being noisy, I'll keep enjoying moments like this a little longer.
