The Bnha universe's reaction would be mixed. Those who are into complex stories, like Todoroki, might study the relationships in Hamilton fanfiction. But others, like Mineta, might not be interested at all because it doesn't have much to do with his usual interests. Overall, it would depend on the individual characters' personalities and interests.
Chuuya is not dead in the manga. The author has kept him alive to drive the story forward and create interesting developments. His presence adds a lot of excitement and intrigue to the plot.
Some would be inspired. Characters like All Might might see Peter Parker's journey as similar to his own in some ways. Both are trying to do good in a world full of challenges. All Might could appreciate Peter's determination to protect his city despite having a normal life outside of being a hero.
For heroic - centric fanfictions, they would likely be disdainful. Since they oppose heroes, seeing stories that glorify heroes would annoy them. They might scoff at the idealized versions of heroes in those fanfictions.
It's not okay. Such content can make people uncomfortable and can have a negative impact on the overall image of the fan community. Fan fiction should focus on positive aspects like character development, new storylines within the boundaries of propriety, rather than delving into erotic themes.
Chuuya is a popular character. In chuuya and oc fanfiction, the original character (oc) often interacts with Chuuya in unique ways. It could be a story of adventure where the oc teams up with Chuuya to face various challenges. For example, they might battle against powerful enemies in a fictional city. This type of fanfiction allows fans to explore different relationships and storylines that are not part of the original canon.
Sure. Chuuya has made appearances in certain light novels. These appearances often add depth to his character and contribute to the overall storylines.
Chuuya survives throughout the manga. The storyline doesn't involve his death. Maybe you got some wrong information or mixed it up with another character.
Rather than erotic fan fiction, you can create a fan fiction about Enji's past. Explore his childhood, his family relationships, and how those experiences shaped him into the character he is today. You could also write a fan fiction that focuses on his career or his role in the fictional world, highlighting his achievements, his failures, and how he overcomes obstacles in his professional life.
