The Blue Serpent

The story was set years after the death of Koro-Sensei. Each student has moved onto their own careers. Nagisa chose the assassination business but after years of this job, his new target puts a dent in his reasoning. Can he kill his new target?

Chapter 1


Karma Akabane was once his closest, most loyal friend. Nagisa Shiota valued this red-head more than most. The countless memories they created together in their E-Class adventures were always held dear to Nagisa. Karma was a huge part in the bluenettes decision to choose the assassin way of life; living in various places, never staying in one accommodation for very long. Within this line of work, as the years had trickled by, Nagisa had earned a name for himself. Civilians and clients referred to him as The Blue Serpent. The name was created by his blue hair and the sky-blue eyes that never let a target escape, carrying out each and every task handed to him with the cold, hard nature associated with a serpent.

He had completed endless tasks single handedly, never once failing. When he confronted his target, his eyes were cold and empty, they showed no weakness or emotion as he pulled the trigger or made the final incision with his knife. Each task was swift. This one shouldn't have been any different. He had spent the last few weeks watching his target, effortlessly pushing all emotion and any former bond to the back of his mind. This was his life now and Karma was his next target.


The client that contacted The Blue Serpent barely a month ago had offered a large reward for the task being carried out successfully. The target in question was a well-known government official who was considered manipulative to many people. It wasn't surprising to Nagisa that the client himself wanted the man dead as he knew Karma had defied the wishes of many civilians in order to rise in the ranks. Nagisa remembered reviewing the request with a heavy feeling in his stomach before pushing it aside and destroying the written request for the safety of the client.

During the weeks of observing his target Nagisa has experienced different emotions. He had tracked Karma down and kept his distance as he watched his former classmate carry out his daily routines. The assassin took note of his schedule, eventually learning that the Red-Head would always remain behind at the end of official hours, continuing his work until the night grew dark. Nagisa hadn't noticed anything unusual and perhaps his former classmate's senses had been dulled as Karma didn't seem to notice his presence either.

When he had first laid eyes on his new target the blue haired assassin had felt a rush of emotion cloud his mind. He was slightly confused about the wave of affection and excitement he felt but took no time to question it. As far as Nagisa could remember, he had always felt that way around Karma Akabane, always looked up to him and felt a strong bond, one that many mistook for a stronger meaning. As the weeks passed Nagisa had worked on dulling these emotions, pushing them away and detaching himself whilst carrying out his observations.


Nagisa moved swiftly as he saw the last worker leave the building floor his target was currently occupying. It may have seemed cliché to enter a room through the window but in this case, it was the most viable option. The window was isolated from the open street and faced out onto a detailed landscape. Karma had left the window open for a cool breeze whilst finishing his work. Nagisa waited until the day grew darker and an opening was clear. Once he observed the target move to the bookcase at the opposite side of the room the assassin slipped through the window, gun firmly located in his hand.

He froze.

Nagisa had entered silently and calmly, concealing his presence so effectively that the target who was engrossed in his search through a book had not noticed him. This could have been over so quickly, the silencer on his gun would make it almost silent. The assassin could avoid a confrontation and make an easy exit, so why? Why couldn't he pull the trigger? Nagisa went to retreat but found he could not move as his eyes examined the Red head more closely, tracing the lines of his back, working his gaze up to the man's face. The moment his eyes set upon the man's face he gasped. Only half of the red heads face was visible but Nagisa could tell there was a smile. Karma's usual smirk shone brightly in the dimly lit room as he turned to face the bluenette stood in his office. His face clearly showing that he was expecting the assassin.

How? How did Karma know?


This was my first attempt at an anime fanfiction, i have done others a few years ago based on the show Supernatural. If this chapter gets good feedback i will upload another chapter going into the feelings Karma and Nagisa have for each other and why he couldn't kill his former classmate.

Let em know what you thought in the reviews please, i would really love some feedback.
