A villain like Shigaraki would likely be interested in the power levels in the MCU fanfiction. He's always looking for ways to increase his own power, and seeing the various powerful artifacts and abilities in the MCU might give him some ideas. He could think about how he could use similar things in his own plans to take over the MHA world.
Sure is! Kakegurui originated as a manga and has since been adapted into various forms like anime and live-action series. The manga provides the foundation for these other adaptations.
Some MHA characters might be flattered. For example, Midoriya would probably be really excited and take it as a sign of how much he's inspired people. He might even look for positive lessons in the fanfiction to improve himself.
If the MHA characters were to react to a Mastermind fanfiction, some would be more accepting than others. Characters like Ochaco might find it really exciting. She's a fan of the heroes herself, so seeing different takes in fanfiction would be like getting a new perspective on the MHA world. However, characters like Shoto, who are more reserved, might be a bit hesitant. He might need some time to process what he's reading. But overall, it would be a very interesting scenario as it would show how the characters view different interpretations of their world.
Some characters would be shocked. For example, if the fanfiction had a really dark and unexpected Mastermind plot, like a hero turning out to be the mastermind of all the villains' plans, characters like Tsuyu would be very taken aback. She'd probably question the motives behind such a plot. Then there are characters like Denki. He might be more into it if it had some cool action scenes in the fanfiction, regardless of how out - of - the - blue the Mastermind storyline was. And Nejire would probably be super curious about the emotional depth of the characters in the fanfiction.
A Cypher Visual Novel is an interesting blend. Visual novels usually tell a story through text and images, often with multiple branching paths based on the player's choices. The 'cypher' aspect means there's something secret or coded in the story. Maybe it's a secret language that the characters use, or a mysterious code that the protagonist has to crack to progress the story. For instance, in some Cypher Visual Novels, you might come across a page full of strange symbols that you need to decipher using clues from the story, adding an extra layer of mystery and interactivity to the overall visual novel experience.
Kakegurui manga is definitely worth a read. It offers a fresh take on gambling-themed stories, and the tension and drama are maintained throughout. The visuals and the writing work together seamlessly to create an immersive experience.
