Ansatsu Kyoushitsu fanfic [Karma x OC] [On Hold]

Chapter 1

"I knew this is sudden, but you all got a new 'provisional' classmate today. Come on in." As Karasuma-sensei asks me to come in to the class, I opened the door, walked and stopped next where he stands. I turned around and face all of my new classmates. "My name is Yuki Akamaki. That's all."
Siiiinng... (lol sfx quiet like)
"Is that all? You're not gonna introduce yourself properly?" Karasuma-sensei asked me. "Why would I? My name only is enough." I give all of the E Class' students my cold-fiercing-eyes-look. "Hope we can get along well, Akamaki-san.." one of them stand up from his desk and smiled sheepishly at me. He has this two hair antennas and an ikemen-look-like face. 'Get along?' I thought of it for a sec. 'Why? Why would I get along with all of you?'I thought it again. "Isogai-kun, Everyone, like Karasuma-sensei said, Yuki-san is a 'provisional' student in this class. After a semester in E Class, she'll be transferred back to the main building. But, she will join our assasination too because the Head Director said so. And from today on, I'm your teacher, Koro-sensei. Let's have a fun assasination semester together~ Nyurufufufu~" A yellow-octopus-thing-like suddenly appeared out of nowhere and he's now standing next to me. He offered his tentacle-hand-like to offer a handshake to me. I handshaked with Koro-sensei's jelly-like tentacle(or hand lol) and it's actually squishy and soft and... a bit slimy. "And I'm a teacher and a pro assasin also, Irina Jelavic." A blonde-haired woman who is known as 'bitch-sensei' in this class introduces herself for me. And of course, The Head Director, Gakuho Asano already told me everything about Koro-sensei and the assasination attempt of E Class, Karasuma-sensei and Irina-sensei as well. So I'm not really shocked about Koro-sensei and the assasination. He told me to study at E class for a semester too. Why does the Head Director told me so, you ask? Of course, because I'm his spy.
