Unable to leave you (Nagisa x reader)

Season 2 part 11

Two green tentacles rushed towards me. I closed my eyes in fear and then I felt Itona hugging me. I heard gun shots firing and then silence. I opened my eyes I saw Kayano's body laying on the ground and blood was coming out of her. Nagisa was covered in Kayano's blood and so was Karma, Teraseka, and Isogai. "Oh dear" said Koro Sensei. "Koro Sensei don't even bother to heal her, after all I'll just kill her again" said Nagisa as he bends down and stick his knife into Kayano's head. "Now Itona could you let go of (y/n), that would be very appreciated" said Nagisa. His eyes looks dull like there was nothing left in him. "I realized that I can't have anyone protect (y/n) from me, so I'll do it after all being with me is both the safest and not" said Nagisa as he loads his gun. "Karma what now?!" Isogai said quietly. Karma's POV: Tch It's either we stand here and let him kill us or we give (y/n) to Nagisa. What to do, what to do, what to do! Wait there's still that option but (y/n) will be sad. No, it's fine this will protect her. "We kill him"

Your POV: "Alright let's do it" said Isogai as they grab they're guns from they're pockets. "Itona you're up" said Teraseka. Itona nodded and then he got up. His tentacles appeared once he took off his bandana. "Oh? So you think you can kill me Hehe...hahahahahahaha ahhhh that's funny" said Nagisa as he runs towards Teraseka. Terasaka quickly dodged Nagisa and then kneed him in the stomach. Then Karma shot Nagisa in the back but missed his heart because Nagisa threw his knife into Karma's arm. Itona shot his tentacles into Nagisa's body as blood spew out of him. "NO STOP" I shouted as I run towards Nagisa but then Isogai grabbed onto me pulling me back. "NO LET GO OF ME! YOU CAN'T KILL HIM" I shouted as I struggle in Isogai's arm. "(Y/n)! Calm down. It's for your own good" Said Karma as he walks towards me. "NO IT'S NOT! PLEASE DON'T KILL HIM!" I shouted as I continue to struggle. "It's all right~" Karma said as he kissed me on the lips. Then I felt him injecting some kind of liquid into me. "No....stop....." everything turned black.
