The 'deku texting story' could potentially revolve around Deku's internal thoughts and struggles as he communicates with others via text. Since Deku is often seen as a determined and kind - hearted character, the texting story might showcase his efforts to support his friends, like when they are facing difficulties in their hero studies. It could also depict how he uses texting to get advice from his mentors, such as All Might. Through these text exchanges, we might get a deeper understanding of Deku's character growth and his relationships in the story world.
No, it's not appropriate. Deku is a character with his own depth, goals, and story within the MHA universe. Fanfic should aim to explore his hero journey, his relationships in terms of mutual respect and support, not create content that focuses on inappropriate or disrespectful ideas like this.
In the 'deku texting story', Deku is the central figure. However, considering his world in My Hero Academia, other characters who could play major roles in the texting story are numerous. His friends from Class 1 - A would be prime candidates. They are constantly interacting with Deku in the original series, so it makes sense for them to be in the texting story. Additionally, any heroes or sidekicks that Deku looks up to or works with might also be main characters. Their wisdom and experience could be shared through texting, and they could offer guidance to Deku during his journey to become a great hero.
Often, the theme of growth is present. Deku is constantly growing as a hero, and Midnight could play a role in that growth, either by inspiring him or directly training him. And there could be a theme of the unlikely pair, as they are quite different in age and personality, which makes for an interesting dynamic in the fanfics.
One popular Midnight x Deku fanfic might be 'Midnight's Guidance'. In this fanfic, Midnight could be portrayed as a mentor figure to Deku, guiding him in ways that are different from his regular teachers at UA. She might use her unique quirk knowledge to help Deku enhance his own quirk.
One common theme is mentorship. All Might is Deku's mentor, so a lot of fanfics explore how he guides Deku, like teaching him how to use his power effectively.
