This is an anthology story, which tells about the adventures of 3E in the 15 years of time gap between the my main story, 'My Sensei is an Assassin' and after the assassination of Koro sensei.
This story will tell you about their school life, personal life, formation of their undefeated team.
If you are a reader of my other story, then this will help you, and if you aren't, then it will only confuse you more. The timelines are jumbled together because I get good ideas very late.
I do not own Assassination Classroom or MHA. All rights go to their respective authors. I am just a fan of their work.

The Hero With Many Faces. (My Hero Academia) [Discontinued]
Salazo Nautali graduated from Kunugigaoka junior high by killing his teacher; Koro Sensei. After being recommended to U.A. by Mr. Karasuma, he starts his hero education. His "quirk" is something even he can't explain. It caused problems for him in the past, and is still causing problems now. The only thing he can call it is a mental disorder. Salazo hopes to be a hero even with this setback. So many secrets he's hiding. What could they be? What happened in his past? What is his quirk? Why were three students accepted into 1-A based on recommendation? [The story is now discontinued. It was the first thing I wrote for Wattpad so it's not the best, but it will forever hold a special place in my heart. I'm sorry to anyone if still cared about the story] Sorry in advance for any typos. I only own my characters, the story and 99% of the characters don't belong to me.Complete

When a revenge plot, gone wrong, drags the entire class into the problem how will they overcome it? Especially since the plotter won't rest till the student is suffering. Find out now! ... This story is set before Koro-Sensei is killed, so after season one and before he is killed. Sorry I can't be more specific. Also, aplogies if it's quite slow at times or through out, I kept having ideas and then loosing them and I also have a tenancy to babble and add much detail when it might not be needed. Note: There is KarmaxNagisa hints and moments in this fanfiction. Disclaimer: I do not own any of the characters or rights to this anime.Complete

This work is not related to my other work, Assassins and Heroes: The Field Trip. I mean, it might when we get going, but still. It'll probably diverge so like yeah.

And What relationships lay ahead? Will she be able to assassinate her target? Read to find out Also, this story is going to follow the same E-Class time line but I will be changing slightly and they are going to be in high school so around the age of 18 I'm also in the processes of editing this story again, as I am cringing as I read through. originally I had planned on not removing the story while editing, however, what I have edited has changed this story significantly from the original. So in order to not confuse any new readers I have removed the unedited chapters as the transition between new and old would not have made any sense. I also do not own any images or videos unless stated so in the chapter. ⚠️ TRIGGER WARNINGS ⚠️ STRONG LANGUAGE! ⚠️ ABUSE/VIOLENCE ⚠️ GRAMMAR ERRORS Last edit - jun 25th - sept 20th 2019 New edits - Sept 15th 2022 - presentComplete
