End of the line. (Karma x Reader x Nagisa)

Poison

The day was insanely fun. You played in the ocean with your class, mostly Nagisa and Karma. However, you did play chicken with Sugino and Kanazaki. Before the assassination plan of course. That would happen at night. You had a special role, While everyone was shooting Korosensi with BBs you would be acting almost like a piranha and jumping up cutting off his lower tentacles.

Korosensi set up a "cave of courage" you refused to go in, as well as karma, later Nagisa pushed you two into the cave pouty from having to go with Kaede and not you.

After the long day you sighed and sat down ready to eat with everyone. A waiter placed a note on your table.

"Told you!" You laughed looking to Nagisa and Karma, but when you opened the note your heart dropped.

It was covered in what looked like blood, It was definitely assigned to you. There were a couple definable words, Poison, Jokes on you, Can't do amything.

"Th-this..." Your eyes teared up. "This isn't from Asano... This is scary.."

"What the hell?!" Karma looked so concerned at the note.

"What type of creepy stalker wrote this...." Ms. Jelavic said.

"It's not Asano's handwriting.. the pencil scratches.. The blood is really thick, it's almost creepy that it didn't go through the envelope." You mumbled. "Unless this is someone from m-"

You paused your eyes widening in some sort of twisted fear. "What is it?" Korosensi asked. "Do you have any idea who this might be?"

You pulled out an old letter from your ex boyfriend laying it next to the new note. You threw up, you literally had to rush to the nearest trashcan to puke.

"Y/n... Who is this?" Korosensi asked.

"Um.. before I transferred schools I had a very mentally unstable boyfriend... But-" You heard someone hit the ground and fear coursed through you. "Maehara! Maehara!!" You rushed over helping him up. "Holy hell! He's burning up!"

"He's also bleeding." Nagisa said creeped out. You kicked your bag over and your blanket rolled out. You handed maehara to karma making a temporary bed for him. You laid him down and saw the amount of your class mates that had hit the ground.

"Oh god... This is all my fault.." you said fearfully. You looked at the note again, some blood had dried and revealed a couple more words.

Dear y/n,
Hey there... Remember me? Doesn't matter if you don't.... I poisoned you and your classmates, you can't do anything about it, jokes on you, you should have...dhu- ue.jwkkfbdjlansvfeijfkclnsnkxkdndbdkfknfndjdokdndbdjdjjd.
Sin.kserly,
Fjjejsii.

"None of this is your fault y/n... It couldn't have been organized by just a mere 3rd year." Karasuma said.

"...He said he poisoned me." You said confused. "...He is well aware that most poisons won't work well on me due to my immune system..."

"Than the other person isn't actually aiming for you." Korosensi said. The TV turned on and suddenly and a voice changed man begun speaking.

You couldn't focus much you were busy helping the poisoned students.

"What do you mean I can't kill anyone boss!?"
