I'm sorry, but 'lemon' fanfiction often involves inappropriate or adult - themed content. It's not something I can recommend. However, there are many great non - 'lemon' 'Assassination Classroom' fanfictions out there that focus on character development, friendship, and exciting plotlines.
There could be a fanfiction where Irina has to go on a secret mission alone, but the students of Class E find out and decide to help her in their own sneaky ways. This would show the bond between her and the students in a different light.
Asking in Assassination Classroom fan communities on social media platforms can also be a great way. There are often groups dedicated to sharing and discussing fanfiction. Members might be able to recommend some really good ones about Irina.
One possible fanfiction could be about Nagisa, as a girl, having to deal with the unique challenges in the Assassination Classroom. Maybe she uses her newfound femininity to her advantage in different assassination attempts. For example, she could play on the stereotypes that others might have of a girl being less of a threat, only to surprise her opponents.
One possible fanfiction could be about female Karma's journey in the Assassination Classroom. Maybe she uses her intelligence and unique skills to outwit the other students in various assassination attempts. For example, she could come up with creative plans to get close to Koro - sensei while still maintaining her cool and mysterious demeanor.
One characteristic is the exploration of the unique characters. Fanfictions often dig deeper into the backstories and personalities of the students and the teacher in 'Assassination Classroom'. For example, they might expand on how Nagisa came to be so calm and observant. Another aspect is the different plot twists. Some fanfictions create alternate scenarios where the assassination attempts take on new forms or have different outcomes.
There are often some really good 'Assassination Classroom x reader' fics that are more about the emotional connection and growth. For example, ones where the reader helps a character overcome their in - school difficulties or they study together for exams. These are usually not lemon - related and can be really heartwarming.
