All Tied Up (It's not as kinky as it sounds)
WARNING: THE GORE IN THIS IS FUCKED UP, READ WITH CAUTION, OR DONT. YOUR CHOICE. GO TO BOTTOM FOR SUMMARY IF YOU DONT LIKE GORE.
When Nagisa got that challenge, he assumed "KIDNAPPERS" was a metaphor for something, but he soon realised it literally meant kidnappers. Him, Karma, Sugino, Kaede, Manami and Yukiko were jumped by the exact same people who decided to fuck with the girls on the train, the exact same people who Nagisa and Karma both tied up so that they wouldn't... Get in the way.
So, yes, it came back to bite them in the ass.
All of those strange looks that Nagisa got when he came out of the bathroom with his hair down, a girls uniform, and a tiny bit of makeup were worth it, and he's never been so thankful of his mother's weird need to dress him up as a girl.
As far as these guys are concerned, the only person they can get revenge on here is Karma, because they don't think Nagisa is here. Cross-dressing really does do wonders.
Karma (obviously) attacks first, because it would be way too out of character for him to not, and then Nagisa sneakily runs up behind one of them and kicks them in the shin (shamelessly). They are quickly outnumbered, but that's to be expected. Nagisa doesn't like the way these guys grab him, but what's a guy to do?
The things he does for his classmates.
Karma falls to the ground after a kick, and Nagisa has to resist the urge to help him out, because Karma is the only person here who isn't a complete idiot. He's much less idiot than everyone else.
Nagisa isn't worried when he's dragged - with the rest of the girls in his group (minus Manami, because she ran away) - to an abandoned-ish warehouse, or whatever this dump is, because he has a plan. And one thing that you should always know about Nagisa Shiota, is that he always has a plan, and it always goes right.
"Kaede, Yukiko, close your eyes, something's coming" And they do, because they think it's Koro-sensei, who, when royally pissed, can definitely kill something. Of, course, Nagisa doesn't mean the useless octopus that a little too much of a show off.
He means something far far worse."Haha, funny, this little girl thinks someone's coming to save them" The leader of the idiots (the term idiot is a spectrum, and unlike Karma, who's quite low down, these guys are the highest form of idiot) grins, and it makes Nagisa pretend gag, because thus guy is fucking ugly.
"So who's coming for you?" Another one says in a mocking tone, and Nagisa smiles. A smile far too wide and far too wrong.
CHALLENGE: KILL THE KIDNAPPERS TO GAIN EXP.
Suddenly, Nagisa isn't tied up in rope any more, and isn't cowering I'm fake fear. He's right next to the obnoxious asshole, hand on his shoulder and face right next to his ear. He whispers, because he doesn't want the girls to hear, thus giving away his little game:
"Me"
The system boosts up again, giving him all the information he needs. EXP LOCATED IN THE LEADERS HEART. He hopes Koro-sensei doesn't come yet, because he really needs, wants, this EXP.
As said before, gathering EXP isn't fun - for normal people. But Nagisa isn't a normal person, he's a monster who's slowly losing his sanity, so he'll savour every plea, and scream and cry for help. Because it's delicious.
He's glad he's been saving up his stamina all day. He sends a kick at the guys ankles, reinforced with a lot of power, because Nagisa has a lot of power. It breaks with an all too satisfying crack, the guy screams like a girl, and the girls wimper from fear, eyes still closed. They better keep them like that if they don't want to be traumatized.
Ankle bent out of shape, the guy deperately tries to crawl away, and Nagisa let's him, for the most part, because false hope is delicious. He moves on to the rest, pulling out his trusty knife. A fresh wave of exhilaration courses through his body as he slices and plunges and stabbed with the knife, loving the metallic scent of fresh blood.
The girls are shivering, but Nagisa doesn't care about how they feel, or how scared they are, no, he only cares about it they are alive, because the inconvenience is too much if they decide to kick the bucket. He almost feels sorry for everyone in this room, apart from himself. Almost.
Once there's a pile of dead bodies, Nagisa turns to where the loud scratches are being made to left of him, and sees the leader if this gaggle of fools trying to escape. How pitiful a sight it is, and Nagisa licks the blood off his hand, like an appetizer, but nothing can prepare him for the meal he's about to have.
The leader squeals like an animal when he sees how close the monster is, his eyes widening with tears flowing out. Nagisa can't blame him for being scared, but he did get himself into this... mess."P-Please, no, I'll do anything" The guy squeaks out, but Nagisa smiles, eerily calm. Not that emotions have ever really gotten the best of him. No, only anger does that.
"Aww, but I need the EXP" He says in a sickly sweet tone, eyes glinting in amusement. The leader cowers further into the wall, as if trying to phase through it. The girls didn't hear Nagisa, so he continues.
"You got yourself in this mess, so, as a special gift just for you, I'll carve out your heart while your still conscious"
He's surprised this guy hasn't literally pissed himself, but he's squealing like a pig, so Nagida can't respect him for it. He brings the knife down, the guy struggling, before bringing it down and cutting.
There's a moment of silence, a beat, a second, and then an ear piercing scream echoes throughout the warehouse, making the girls shake even more, the building shake, and Nagisa smile even wider. Beautiful.
Once he pulls out the still-beating organ, the guy dies, an everlasting look of dread, despair and pain mixed together still on his face. Nagisa loves it. He brings the heart to his mouth and gives it a kick, before biting into it like a peach. Blood dribbles down his chin, his eyes widen, and he giggles.
It's amazing. Delicious. Better than a three coursed meal at a five star restaurant.
DISPOSING OF EVIDENCE IN 3 SECONDS. 500 EXP GAINED.
The game isn't allowed to interfere with the real-world too much, and a bunch of disturbingly cut up bodies to the police would be too suspicious, so they all disappear, leaving Nagisa to tie himself up again, no longer soaked in blood.
So, Nagisa dresses up as a girl, gets kidnapped with the girls, kills all the kidnappers and gains EXP. The girls don't watch, because they think it's Koro-sensei, and he kills people sometimes too, so they keep their eyes closed.The evidence is disposed of by the game, and Nagisa ties himself back up, waiting for Koro-sensei (who they think is already there) and the rest of the group.
