The Devil Duo (Karma x Reader)

Part 25 (Discord time)

The days flew by at lightning speed. So much happened since the summer festival. Kayano's assassination attempt, Itona's detachment from Shiro, the second wager with A-class, midterms, escaping The Reaper, the final exams which Karma placed 1st in and Y/n placed 2nd place along with Asano, and possibly the most heartbreaking thing so far.

Koro-sensei's true backstory...

He had been the original Reaper. The world's best assassin and his one and only student betrayed him. Something that resulted in him becoming an experiment for a mad group of scientists led by Yanagisawa.

Now that everyone knew the truth about what happened to the moon- how Koro-sensei would reach his absolute doom, they were all devastated. He worked so hard for not only 3E but for himself and Aguri Yukimura, Kayano's older sister. He wanted to avenge her for the death that he indirectly caused and pass on her legacy to his students. 

Her precious E-class students.

Even though Y/n had her suspicions at the start that he was some sort of experiment. She never would've guessed that it would've been so brutal and heartbreaking. The reason they had to kill him, their beloved teacher was because of his deadline. 

March 13th... his absolute breaking point. The day where he'd die, and along with his self-destruction, take the whole world with him.

And in some twisted way, that very same date... was 3E's graduation day.

-Time skip- (to after the winter break)

"I want to save him," Nagisa said as everyone stood around listening. "I don't know if it's even possible, but I want to find a way to save Koro-sensei's life."

"Save him?" Takuya asked.

"You mean, you want to find a way to prevent him from blowing up?" Bf/n asked, making Y/n give her a disapproving nudge. The tone Bf/n used was hostile almost.

"But where do we start?" Yada asked as Nagisa lowered his gaze towards the ground.

"I don't know yet, but..." Nagisa said before he was cut off by Kurahashi.

"I'm in! I wanna go looking for more creepy crawlings with Koro-sensei!" She said as Nagisa smiled.

"If you hadn't said anything. I would've. I want to repay him" Kataoka said as she stepped into the light and towards Nagisa.

"Yeah! Let's tackle a new challenge!" Sugino said with a smile, as Y/n looked around for Karma. However said boy was nowhere in sight.

After about half of the class, began to say that they agreed, Y/n registered a movement on the left side of her.

Walking out of the woods was Rio, her face was serious, eyebrows knitted together in a frown. In one fellow swoop, the lone girl managed to shift the whole atmosphere.

"I hate to spoil the mood, but I'm against the idea." One sentence was all it took for the hopeful, upbeat aura, to completely shatter.

"Our bond is that of assassin and target. Koro-sensei said as much. I really treasure the bond we built over the past year." Bf/n said firmly standing beside Rio, as Y/n frowned.

'This is gonna turn ugly' She thought, looking over at the rest of the class, eyes finally landing on a figure in the shadows.

"That's exactly why... I think we have to kill him." Rio said as Bf/n nodded.

Karma was casually leaning against the tree, but to Y/n it was clear that there was more than meets the eye. His golden eyes gleamed with untold emotions. A crude mix of conflicting feelings and opinions.
