Demons...Eight years ago, they invaded our world. All of humanity was on the brink of extinction. Cities fell one after another, turning to ruins. People lost hope. But then came a squad capable of fighting back – the Demon Slayer Squad, or simply DSS. Their sole purpose was to eradicate demons.
Becoming a cadet in DSS isn't difficult; you just have to reach 18 years of age. And today, I turned 18. Why do I want to join? The answer is simple: revenge.When I was a child, I watched as my mother was killed. It wasn't just any demon, but an intelligent one. I remember it in vivid detail:Its eyes were bottomless, like black holes, with crimson rings around the pupils.Its skin was semi-transparent darkness, as if its body was woven from smoke and blood, ever-shifting.Its horns were two sharp white spikes, cracked as though cursed by the gods themselves.Its clothing was a cloak made of living shadows, whispering pleas and screams.Its voice was dual, as though it spoke with someone else trapped within it.Its height was about four meters. Its presence darkened the sky and chilled the blood.I hid under the bed, too scared to even breathe. And I still don't know what my mother felt in that moment. But her last words are burned into my soul:"You mustn't be a hero, son... You must be... free. Free from our lies, from their protocols, from my curse. I betrayed love to save lives. But all I did was ignite a war. Forgive me for the world I brought you into... But it is you who can end its pain. Don't become like me... become better. Break everything — and create it anew. And if you see him... tell him I... still... loved him…"At that moment, the demon didn't just smile — it was something else. Horrifying, otherworldly. Such a smile can never be forgotten.Since then, I have hated demons. I swore to take revenge. As for my father?.. I never knew him. My mother said he left when I was a baby. And you know what? Fine. I've always hated him. I'm sure he's long dead, killed by demons.
Present TimeNow, I stand at the gates of the Demon Slayer Academy. I knocked. A minute later, a man appeared — tall, in a professor's uniform. White hair, icy gaze. He held his hands behind his back, as though everything in this world was under control.He looked at me and asked:"Who are you? Why have you come?"His voice... it felt cold, like a winter storm."My name is Kairon Sage. I've completed the application process. Here's my card," I said, handing over the document.He laughed:"Hah, brave one. You think you'll last longer than a day here?"But, upon seeing my eyes, his tone changed."Fine. Follow me."He led me to the cadet class. I took a deep breath and entered."Hey everyone. My name is Kairon Sage. I'll be studying with you from now on."In response — a deathly silence. All eyes were locked on me, cold as ice, as if they wanted to kill me. I instinctively took a step back.Suddenly, one of them stood up:"Are you here to play? This isn't a place for weaklings like you!"I gave him a deadly stare. He was ready to fight, but suddenly the teacher's voice cut through the air:"Enough. Back in your places!"Everyone quickly obeyed.

The teacher introduced himself:"My name is Hideo Katsuragi. From today, you are cadets of the Demon Slayer Academy. Training and lessons will be difficult. Some of you may die. Let me ask you again: are you ready?"Everyone answered in unison: "Yes!"We were given a tour: dorms, the dining hall, classrooms, training grounds, sparring arenas. But most importantly — the academy archive. Access is prohibited. Violators are either expelled or killed.Naturally, this sparked everyone's curiosity.We all went to our dorms. Boys in one, girls in another.I was about to go to sleep when suddenly Zaiko Ren approached me:"Hey, rookie. Let's have a sparring match with wooden swords."He threw one at me. I accepted the challenge, even though fighting at night was prohibited.The fight was brief...
