Follow the Phantoms as they go on all new adventures and gain new members in their ranks. New faces, new family, old friends, fierce fights, new targets, new assassinations, and new danger. Life is exciting when you're a Phantom Assassin. And (Y/N) and Karma are training six of them. (This is a sequel to my Karma x Reader Red and Black Blood. Go and read that story before reading this one if you are new to the channel. However if you are fimiliar with Red and Black Blood, welcome to the long awaited sequel dear readers.)

Insanity and Bloodlust. Two things famous detective Karma Akabane was extremely familiar with. But no matter how familiar he was with them, in the detective agency they were Taboo subjects around him. After all, talking of insanity and Bloodlust ended up turning into conversations about the detective's, 'past occupation'. Which wasn't pleasant for anyone in the agency. Especially Karma himself. So what if he was an ex-assassin? He wasn't who he used to be! At least, that's what he thought..... Insanity. Pure and utter insanity was all (Y/N) had known in her life. She was born insane. But she never let it take her. She fought tooth and claw against the insanity. But eventually she gave up and plunged into the deep end. Where she found, insanity wasn't bad. It was pleasant. It was empowering even! She adopted the name Joker, and now rules the underground as the head of an organization known as the Dark Knights. The Dark Knights are well known all across Japan. But no one had drawn the conclusion that the murderer known as Joker was related to them. Until the case found itself on Karma's desk. All eyes turn to the battle between the most insane of the insane and the craziest of the sane. Will Karma pull Joker out of the waters of insanity? Or will she drag him down to the bottom with her? Only time will tell....

Basically Red and Black blood only the Koro Quest version.

D I S C O N T I N U E D [Ansatsu Kyoushitsu x Reader] ( • з • ) •~•~•~•~•~•~•~•~•~•~•~•~•~•~•~ "Minna-san, I think this is the new transferred student. Come in now. Nyurufufufu~" Koro-sensei said. However as soon as the door opened, a knife was thrown in a blink of an eye and three shots have been heard. Resulting to the loss of 3 tentacles but Koro-sensei caught the knife with a paper. The class was quiet. Too quiet. I can't believe what this student has done. It's like he or she has been trained to kill him. Seconds later, there stands a (H/L) (H/C) girl but her face shows cold boredom and a glint if mischiveousness. As if saying 'Worth a shot'. Then she smiled, not a real smile. There was a hint of amusement this time but with an emotionless face like her, she masked it. Like she's been doing it for years. "Ara~ I didn't know it will work that easily. But I apologize for my rude behavior. By the way, I am (L/N) (Y/N). Yoroshiku~" She said while smiling but as a blink of an eye, the smile was no longer there. She turned to Koro-sensei and said, "Sumimasen, sensei, I acted in inappropriate way even though I just met you all." Then she bowed. Koro-sensei's face turned into fear and panic, even with his usual face, for a second as he glanced at the girl and the class is still shocked to see how in a few seconds three of Koro-sensei's tentacles were cut. She even beat Karma's technique! This girl... ... I can't even explain it how I felt. She'll make this class a lot more exciting. -------------- Hey guys this is my first fanfiction sooooo, there's still some grammatical errors because I'm not that fluent in English. Also, I will include some of one-shots in here if I had an idea. ~\(≧▽≦)/~ Edited (2024): If you want to adopt this story, you may do so! Just tagged me in your story or in one of your chapters. I do not own Assassination Classroom.

A mysterious girl transfers to E-class, she is almost too good at stealth and close combat. How is this possible? Who is she? And why is she always the first there and the last to leave? Are many questions the students ask each other but only her and the octopus know... Despite how suspicious she is she seems to have taken a liking to Karma, and him to her. This story I think I will make it slightly differ from the original plot, including some bits but making them my own. I will not go with the original ending and it is still yet to be figured out. I DO NOT OWN ASSASSINATION CLASSROOM, I ONLY OWN MY OWN CHARACTERS AND MOST OF MY PLOT.
