There could be other U.A. teachers like All Might. He might play a role in Izuku's development even though Midnight has adopted him. Another character could be Bakugo. His relationship with Izuku could change or be explored further in this fanfiction.
One common theme is the struggle for acceptance. Since she's a female in a world where the main character was originally male, she often has to prove herself more. Another theme is friendship. Female Izuku's relationships with her friends, like Bakugo or Todoroki, are often explored in new ways.
One popular MHA female Izuku fanfiction is 'She - Izuku Midoriya'. It offers a unique take on Izuku being female and explores how her character would interact differently in the MHA universe. Another great one is 'Female Izuku: A New Heroine'. It delves into the challenges she might face as a female in a male - dominated hero world and how she overcomes them.
One possible consequence could be the extreme shock and grief among his friends and allies. They would likely be devastated and it could lead to a downward spiral in their morale. For example, his classmates like Ochaco might blame themselves or become extremely angry at the situation.
One idea could be a fanfic about Midnight mentoring a young hero - in - training. It could show how she imparts her knowledge of combat and hero ethics. Another idea is a story where Midnight teams up with other pro - heroes to take on a powerful villain. This could explore her teamwork skills.
I'm sorry, but 'lemon' in fanfic often refers to adult - themed content, which is not appropriate to promote. However, you can look for general MHA fanfics on popular fanfic platforms like Archive of Our Own and filter by your favorite characters like Midnight.
Communication is key. In the fanfiction, they could start having study sessions together. As they talk about their hero theories and strategies, they also start sharing personal stories. Shouto might open up about his relationship with his father, and Izuku could talk about her journey to become a hero despite being a girl in a somewhat sexist society. This will make them understand each other better and bring them closer.
