ok lets first start off with me saying I was forced to be here by the octopus AKA Korosensei, and the government at the time of my arrival just decided to roll along with the punches and threw me into class E giving me a job, said job was simple, be their councillor, that sounded easy right? I didn't think so, OOC SI

The world ends and the clock ticks back. Four children and an AI are sent back to the start. This is their tale of struggles and discovering their true purpose in life, even if that purpose may be killing all those who ruined their old lives. (Spoilers up to 148)

At the very last moment of his breath, they thought it was over; that assassination is done. Or so they thought. What they thought was the end was only the beginning. They had never thought of it up until now. [Time Travel AU]

The first few years everything was alright. Nagisa was leading a happy life, he was a teacher, had friends, his family was coming back together. What could possibly go wrong? Then came the nightmares, the treacherous thoughts. He starts spiraling into depression and no matter how much Akari tries, not even with Ritsu's infinite well of knowledge, can she pull him back. Time-Travel

Someone once asked me what I would change if I could go back in time. My answer: everything. I traveled back 25 years! I guess I got a do-over. Maybe I can be with her now.

The last battle is going terribly wrong. Koro-sensei is injured, and the fatal blow is about to be dealt when the unexpected happens. Four students, Nagisa, Karma, Sugino, and Okuda, rush to Koro-sensei's side. Expecting death, they instead find themselves transported back to the beginning of the school year, when they could possibly change everything...Time Travel

Nagisa Shiota has never enjoyed his life. The only thing stopping himself from death was Karma. Nagisa is unstable and mentally ill and the fact that his younger self and classmates time travelled to his current life is making it worse. Will they get home or will they watch Nagisa slowly die?

It was their moment. Their killing time. It was the story of a girl being reborn as Yukimura Aguri. She had no obligation to do anything yet still did it anyway. She vowed to save the yellow octopus teacher with her own hands. Even at the cost of her own life. OC-is-Yukimura Aguri x Koro-sensei/Former God of Death

Death hurts but reincarnation into the world of assassination classroom is great with my otaku knowledge (First fanfic so please give me some pointers in the reviews if you can) (T for cussing) PS: genres may change PPS: Re editing so please wait for now.

"stranger things happen when one tries to cheat fate." Aomi just wants to get out of class 3-E but apparently she needs to kill her alien teacher— but what do you mean he destroyed the moon? That was when things got personal. [[reincarnated!oc / SI OC]] Originally posted on AO3.

Dying isn't something I thought would be happening to me anytime soon so dying via the most cliche fanfiction way isn't how I thought I'd go. Neither was being tasked with saving koro-sensei and Aguri. Anime Characters. In an Anime. Oh another thing. WHY AM I A BOY! Warning Spoilers, BL, and Crazy-Ness. Please review, I like to have any sort of constructive criticism, good or bad

After dying I didn't expect anything. Maybe even hell, but not a new life. I hoped to enjoy that life to the fullest and not to leave too many regrets behind. Well, I guess killing my own teacher, who planned to destroy the earth in one year, with my best friend was kind of nice too. SI!OC

Words can give you a lot of power. It can cause you to have friends, to lose friends, to gain enemies. It can help you to win through a battle, cause you to lose in a battle. Words can make someone feel like trash, but words can also make someone feel like they're important. Words, can make someone fall in love. (OC Reincarnation fic)

Life is strange. A simple shoujo scenario can lead to you being transferred to your favourite manga. Who knew? Definitely not Aki. -Rated T just in case- I do not own Assassination Classroom.

There was an anime lover girl from the real world. One day, she woke up in Ansatsu Kyoushitsu's world. All of people in Ansatsu Kyoushitsu's world thought she had lost her memories because she didn't recognize them. Actually, she was in another person's body named Miu Yamashita, one of students in Class A. What happened? And suddenly there was a fairy? Then she ended up in Class E?

SI-OC as a student of Kunugigaoka. Will Kotone be in E-class, or will she continue to pursue her dreams? "He was on the other side of the screen and helped me come to terms with a lot of things in the before. It just seems that I have outgrown the need for a role model, a teacher."

Four girls from our world - best friends - ends up in the world of amnesia (anime). Each of them with a chosen path. Now they all must learn to live in this new world and with possible boyfriends. What could ever go wrong? ShinxCiarda(OC) TomaxXaria(OC) KentxNaiya(OC) IkkixKera(OC). I obviously do not own Amnesia.

When Itami and her brother get sucked into the world of Amnesia and Itami manages to fall for one of the boys, Will she want to leave when the time comes? T rated for the moment, but that might change down the line ;}

When Saki Kumo ends up in the game amnesia, she only has a week to find the truth behind her past and get Shin to fall in love with her. And This game she can't afford to lose, for losing mean erasing her very existence. Shin/OC

She wasn't quite sure what to make of her situation. Suddenly appearing in a time that was oddly reminiscent of Feudal Japan and even Ancient China, what was she supposed to believe or do? With talks of mystical "curses" and dragons, and war and death every time you turn a corner, it could almost be considered a nightmare. Rest of summary in story.

When I was born, I dreamed about an odd world with buildings that reached the sky and odd vehicles. I dreamed about a young man who hid behind fake smiles surrounded by those who cared for him, but he didn't care for them. I was different from him, I have people I care for. I'm female, a sister, a daughter, and cherished friend. Oc Male to Oc Female. Oc POV
