Saiga Matsushiro had been discarded into a dungeon, left for dead. Against all odds, he had defeated a monstrous Hydra by unlocking the hidden potential of his mysterious skill, **[None]**. The beast was slain, but his journey was far from over.
As he lay resting, a voice interrupted his thoughts.
_"Wake up, boy. Wake up, I say."_
The voice was neither distinctly male nor female, but it carried an eerie authority.
_"You're not dead, are you? Get up, boy."_
Groaning, Saiga slowly opened his eyes. He sat up, confused but alive. _Yeah, I'm still alive._
_"Over here, boy."_
He glanced around but saw nothing except the remains of the Hydra. Then, his eyes fell upon something strange.
_"A treasure chest?"_
Sitting where the Hydra's corpse had been was a large chest, its polished surface gleaming. Saiga's curiosity got the better of him, and he opened it. Inside lay a dark coat and a sword.
_"What the hell? A coat and a... sword?"_
_"That's no ordinary sword. It's a cursed blade."_
Saiga flinched, the voice returning. But it wasn't coming from anyone around him—it was coming from the sword.
_"No way... are you talking?"_
_"Indeed. It seems you are worthy of wielding me."_
This world, it seemed, had even stranger surprises than he imagined. A talking sword.
_"What are you?"_ Saiga asked, lifting the weapon from the chest.
_"I am the cursed blade known as **Shichifukujin**."_
_"Shichifukujin? That's... a surprisingly lucky-sounding name for a cursed sword."_
_"Luck had nothing to do with it. I was once a master blacksmith. When I forged this blade, my soul was devoured by the very sword I created. Now, I am bound to it for eternity."_
Saiga hesitated. _A sword that consumed its creator's soul? This thing is dangerous._
_"Wait, boy. Don't be so quick to abandon me. You survived the Hydra's venom. That means the cursed poison that flows through me will not harm you."_
_"And why should I believe that?"_
_"The poison that Hydra used—it came from me."_
Saiga blinked. The sword explained further, claiming that the Hydra itself had been created from **Shichifukujin** and another artifact—the black coat lying beside it.
_"Monsters like the Hydra form around powerful objects, drawing energy from them. The Hydra's poison came from me, as I was the core of its being. But you, boy, seem immune to that poison."_
It began to make sense. The Hydra's venom had been linked to the cursed sword all along.
_"Take me in hand, boy. I will be of great use to you."_
Saiga paused. _This sword is... too friendly._
_"Why are you so eager to help me?"_
_"Because I'm interested in your skill—**[None]**. I want to see its true potential, and I can guide you. Having a companion in this cursed place wouldn't hurt, would it? After all, no one likes being alone."_
Saiga narrowed his eyes. _I've been alone my whole life. That doesn't bother me._ But having a guide in this world—a world he barely understood—did make some sense.
_"Fine. I'll take you with me."_
With that, he activated his skill, evolving **[None]** into **[Poison Immunity]** once more. Carefully, he reached for the cursed blade.
_"Ha! As I thought! You are immune to my poison! The deadliest venom in this world has no effect on you. Fascinating!"_
_"Yeah, yeah. Calm down. Now tell me about this... coat."_ Saiga picked up the black garment.
_"That is **Yogasa**, a cursed armor in the form of a cloak. It's lightweight, but incredibly durable. It can protect you from most attacks, but beware—anyone who wears it without poison immunity will be crushed to death by its curse."_
Saiga eyed the coat suspiciously. _Another cursed item._
_"So... it's deadly unless I wear it. That's reassuring."_
_"Don't be so grim, boy. You've already proven you can resist its curse. You're practically invincible when it comes to poison and curses!"_
_"What exactly are cursed items?"_ Saiga asked, slipping the coat over his shoulders.
_"Cursed items possess immense power but come with significant drawbacks. But thanks to your **[None]** skill, you won't be affected by the curses."_
Saiga frowned, still skeptical. _This is all starting to feel like a cheat code._
_"Shichifukujin"_ continued, its tone gleeful.
_"This sword can produce any poison you can imagine—acid, paralysis, sleep venom—you name it. Normally, it would take over the wielder's body and consume their mind. But not you, boy. You're different."_
_"And you're just telling me this now?"_ Saiga grumbled. _What's the catch?_
_"No catch! You're immune to the curse. That makes you special. With me and this cloak, you could become the strongest being in this world."_
_"And how, exactly, do I do that?"_ Saiga asked, intrigued despite himself.
_"Your skill—**[None]**—has limitless potential. With time, it can evolve into something far more dangerous. You could even erase your enemies from existence. Try it. Evolve **[None]** into **[Void].**"_
_"Erase someone from existence?"_ Saiga's heart skipped a beat. _Could that be possible?_
The same voice returned to his mind: **"Would you like to evolve [None] to [Void]?"**
_"Yes."_
**"Skill [None] has evolved into [Void]."**
_"Go on, boy,"_ the sword urged. _"Try it out."_
Cautiously, Saiga raised his hand and focused on the stone wall before him.
_"Void!"_
With a soft **whoosh**, a massive section of the wall vanished into thin air, leaving behind a gaping hole as if the stone had never existed at all.
_"Incredible,"_ Saiga whispered, staring at the void in the wall. _"I can make things disappear."_
_"Yes! You're extraordinary! You've only just scratched the surface of your power, boy. With me and your **[Void]**, you'll become unstoppable!"_
The possibilities swirled in Saiga's mind. **Poison immunity, wound immunity, and now... void.** The cursed items posed no threat to him. He was immune to every poison and curse this world could throw at him.
_"Shichifukujin, tell me... can I kill a god?"_
The sword chuckled darkly.
_"Ah, now we're talking. Yes, boy. With that power, you can kill anyone—even a god."_
Saiga's grip tightened around the blade. The image of the goddess who had abandoned him flashed in his mind. She had condemned him to die in this dungeon, thinking him worthless.
_"Then that's what I'll do."_ Saiga's voice was low but firm. _"I'll kill the goddess. I'll kill her for what she did to me."_
_"Good. Very good."_
He wrapped the black coat around himself, the weightless armor feeling like nothing more than a cloak. The cursed blade hummed with energy in his hand.
_"Let's go."_
_"Yes... a journey to kill a god! I can't wait to see how this unfolds!"_
And so, with the cursed blade **Shichifukujin** at his side and the limitless power of **[Void]** in his grasp, Saiga Matsushiro left the dungeon. He was no longer the weak, discarded boy he had once been.
Now, he was a force of destruction—destined to seek revenge on the very goddess who had cast him aside.
A journey of vengeance had begun.
