Chapter 1
Nagisa's POV
'The Tentacles ask me what I wanted to be.'
And I answered 'I want to be with Karma and save our teacher'
But it's useless now.
Because I feel I'll lost control on my pain.
But I can't lose now.
Or rather mom will be killed by him.
Flasback :
On my way home, I'm walking alone because Karma still having lecture from Koro-sensei
While I'm walking I lost on my mind that wondering what's Karma doing right now or what will I do once I go home
And didn't expect that Shiro appear in front of me all of sudden and kidnapped me.
"Well Nagisa-kun-"
"You'll come with me or your mother will die on my hand as a lab rat" said him while he show Nagisa his mother's photo at her workplace
I'm just froze on my standing place
And feels that he's jab on my back before I lost my consciousness
Not long when I'm waking up, I feels pain crawling so much on my back
I'm screaming and realize that both my hands and legs are in chains.
"Nagisa-kun"
"Now you have to join on my plan"
"If you failed,.....-
-I'll kill her without hesitation"
I feel warm water cover my eyes and cheeks and I've forced to nod
'Why I can't do something' I feel guilt cover my heart
"Sorry all" and I'm crying with all my might
"Ah, also Nagisa-
-I already put bracelet on your right hand, if you want to do any harm to me, it'll inject some poison that maybe could kill yourself, it's smart-bracelet so be careful okay~"
End of flashback
Now I'm sitting in class with over-pain-of-sudden cover me. All I can do just ask for permission to going to the bathroom and crying slowly there. And inject pain-killer that Shiro give to me; he said that I permitted to use this when the pain goes roughly.
3 hours 'till Koro-sensei's death by me
Neutral POV
Karma feels something isn't right from his crush. Everything start when Karma playfully joke with Nagisa and pat his back, it's not a hard pat but Nagisa in slight shows pain and paled of sudden.
"You okay, Nagisa?" Said Karma worriedly
But Nagisa back on his usual smile and said,
"Of course Karma" "why?"
Karma just blushed slightly and shaking his head. "Nandemonai~"
'I know you hide something, Nagisa' Think Karma
Now Karma back to his senses and realize he have to do something to his beloved crush
His second suspicious is when Nagisa seems act when he's ask going to the bathroom more than thrice a day. No matter what, Nagisa never go there that many before. Even normal person do.
Something is wrong with him.
But before he could doing act on Nagisa
It's a little bit late now
On lunch time, right after the bell rang, Nagisa ask Koro-sensei to go to the field now
Koro-sensei also feel like Karma and just follow Nagisa worriedly
As they're both on field, Koro-sensei ask Nagisa "what is it Nagisa-kun? You call sensei all of sudde-"
Koro-sensei couldn't finish his sentences because now he feels 6 of his tentacles is missing and he looks in front of him Nagisa lured out his cry slowly but his eyes shows no mercy.
"I'm sorry, Koro-sensei"
Nagisa hurriedly cut all of Koro-sensei's tentacles
"Nyuya!!!"
As he keeps attacking, he didn't realize that all of his friends already watch them and gasped in their inbelieved
"Eh?"
"What happened?"
"Nagisa?"
"Tentacles??!"
All of his classmates ask in their inbelieve
Karma couldn't take it anymore
"Nagisa!" and run to him
Nagisa stopped his movement to Koro-sensei "get away from me" and he's getting away with a weak Koro-sensei on his clench of the pair tentacles
"I have to do this..." As Nagisa ready to stab Koro-sensei's heart, he lower his guard a bit and don't know when Karma already beside him, tilt Nagisa little bit and kiss him softly. Nagisa surprised. "Calm down, Nagisa" said Karma with his soft smile, not his chesire-smirk. Nagisa somehow become calm but suddenly he feels the tentacles beating painfuly on his back and gasped for breath. As he's doing so, he push Karma away and his tentacles goes wild. His bloodlust wash away by Karma's kiss.
Once Koro-sensei healed slowly and could take an action, he takes Nagisa's tentacles when it's calm a bit. But the tentacles is unusual, when it's pull out from his back, it's growing again. It looks like it's endless.
Nagisa screaming painfully and gasped for air. Nagisa curled up his body and cough harshly until he choked some blood, "NAGISA!" Karma lift Nagisa in a bridal style, feeling Nagisa trembilng hardly on his arms "Hurry up Koro-sensei! Can't you do something on him?!"
As Karma and all of 3-E panicked, Shiro chuckled slowly from the shadows, far away and watching them
"Well, you failed, Nagisa-kun" said Shiro, he smirk happily, his plan work well after all~
