Would You Kindly Slay the Demon Lord? (Konosuba X Male Reader)

Episode 38

We see an alleyway of a random city, as Y/N walks through it, struggling to keep walking after getting his energy drained away by Kazuma in the altercation that took place a couple hours ago.

He takes support of the wall, as he tries to keep moving.

Darkness: We're a mess, Y/N.

Y/N: Stop it..!

Darkness: But we're your mess.

Y/N: I said... Stop...!

Darkness: And you're ours.

Y/N: Shut up!

The voice from the void comes back in his head.

You pushed them away... When you knew they just wanted to help you.

Y/N's eyes widen, as he scowls.

Y/N: You...! What do you want from me?! 

What do I want? No, no, Y/N. The question is... what do you want from me? You called for me, remember? When the pain was too much. When Malceron broke you. I was your answer.

Y/N: You lied to me. You tricked me into-

The void cut him off, its tone shifting to sharp derision.

Tricked you? Oh, Y/N, you wound me. I gave you what you wanted. Strength to tear through your enemies. You were magnificent. But now... look at you. Weak. Alone. And whose fault is that?

Y/N stumbled, nearly collapsing, but caught himself on the wall.

Y/N: You don't know anything. They cared about me. They wanted to help!

The void's laugh was ice-cold, slicing through the fragile armor of his words.

Did they? Is that why they cornered you like a pack of wolves? Is that why they didn't trust you? Face it, Y/N. They're afraid of you. You terrify them, and rightly so. Because deep down, you know you're not one of them. You never were.

Y/N: *growling* Shut the fuck up...!

But the voice continued.

You know what I think? You should thank me, Y/N. Without me, you'd have been nothing. A weak, helpless fool, trapped in an endless cycle of being killed by the same six-armed vassal over and over again until either your spirit or your mind broke.

Y/N: No...! I...

And if it weren't for me, you'd still be trying to fight Malceron, let alone even dream of reaching Skarathor and fighting him. Let's say you didn't need me against Malceron. You really think you could have gotten out of Skarathor's grasp and killed him if it weren't for me? 

Y/N: Just shut up!

The void's laughter grew louder, echoing in Y/N's mind as though it was coming from every direction at once. It felt like the walls themselves were closing in, the alleyway stretching endlessly into darkness. He gritted his teeth, clutching his head as if he could physically wrench the voice out of his skull.

Shut up? Oh, but you don't want me to, Y/N. If I shut up, what will you have left? You need me, even if you hate me. You've built your strength on my whispers, your victories on my power. Without me, you're just...broken.

Y/N's knees buckled, and he slumped against the cold brick wall, panting heavily. His hands shook as he pressed them against his ears, futilely trying to block out the voice.

Y/N: through gritted teeth You're wrong... I can... I will fight without you.

The voice's tone shifted, its mockery replaced by icy menace.
