Consequences of Killing Him
Characters: Shiota Nagisa
When Nagisa killed his beloved sensei, Koro-sensei, that night, he thought he will only carry the burden of a memory, the dreaded memory of Nagisa delivering the final blow in their beloved teacher who truly cares and loved them with all his heart.
He was utterly wrong.
For he had forgotten one thing, the forbidden rule that actually exists in their world.
Imagine the look on Nagisa's face when he woke up looking at a bunch of people with sophisticated high tech gear. Nagisa, being a perceptive person, could infer they were archeologists because of the clothes they are wearing.
They found him.
After a thousand years.
Nagisa cursed under his breath, as he looked at the curious archeologists looking at the cave he was trapped in, then to himself.
He never planned to spend a thousand years, still alive and kicking, just because he killed his precious teacher.
Who happens to be a the former legandary assassin called the God of Death, who happens to kill a THOUSAND people before being caught, being experimented, and becoming the greastest teacher Nagisa and his classmates ever had.
He had remembered what Karma had said to him thousand of years ago.
"I wanted to be the one who killed Koro-sensei, but that rule. Koro-sensei is still an assassin, a killer, even though he is changed. We can't change the rule, Nagisa. Call me a coward, and I don't want you to suffer, but we leave no choice."
"If you kill a serial murderer, because of that rule, you may live longer than any creature here on Earth, possibly forever, unless someone will kill you in special circumstances. You can't kill yourself, you can't be killed in an accident or illness."
"Some of his victims may have a longer lifespan, if Koro-sensei never assassinated them. Those lifespans transferred to him, and eventually to you when you killed him."
"You wanted to carry his legacy, right? You got it, Nagisa. You carried his burden."
"You killed a serial murderer, but you suffer the consequences."
"We will die, but you will live forever."
Prompt:
When you kill someone, their remaining lifespan is added to yours. Archeologists have just found a cavern, apparently sealed off for thousand of years, with a single person living inside.
A/N: I am back here with a new prompt-based fanfic featuring our favorite bluenette!
When I first red it on Writing Prompts Facebook page, I immediately remember Nagisa, so this idea was born.
By the way, I will be trying my best to update some of my stories, but because of writer's block, it will be a little while to update those.
I hope you will all be safe and sound in this ongoing pandemic!
