This article was written for my own selfish reasons. It's sad that Koro-sensei is gone, so I made this up to give myself a happy ending.
The main plot is that the heroine transformed her body at the cost of burning her life to avenge her family, and then discovered that the one who destroyed her clan was the doctor who transformed Koro-sensei. Later, in order to save Koro-sensei, she overloaded her body and developed a medicine that turned Koro-sensei back into a human. After her body was overwhelmed and died, the original plot will have a lot of changes, and there will be a lot of private settings; if you like it, can you collect it? ????っ?
