Another theme is mutual understanding. Despite their different personalities, they seem to understand each other on a level that others don't. Fanfics often play on this, showing how they can communicate without words at times. For example, in some stories, Levi can tell when Hanji is about to do something reckless just by a look in her eyes. And Hanji can sense when Levi is more stressed than usual. This mutual understanding forms the basis of many emotional and plot - driving moments in the fanfics.
Another one is 'Hanji's Perspective on Levi'. This fanfic is unique as it is told from Hanji's point of view. It gives readers a different look into how Hanji sees Levi, their quirks, and the special connection between them.
It's fairly common. Fans often look for more content related to their favorite shows. Since 'Attack on Titan' has a large and passionate fan base, there are a lot of fanfics available. 'Aot' fans might watch (read) these fanfics to explore different scenarios that the official story didn't cover. For example, they might want to see how a certain character would react in a different situation or what would happen if a major plot event had a different outcome.
There could be various fanfictions. Maybe some that focus on alternative endings, like ones where certain characters survive who didn't in the original. For example, a fanfiction where Erwin survives and leads the Scouts in a different way.
It could mean that a person who is a fan of 'Attack on Titan' (AOT) is reading or watching fan - created fictional works related to AOT. Maybe they are interested in seeing different interpretations or storylines that fans have come up with.
One way is to check on popular fanfiction websites. Look for ones with high ratings and a lot of reviews. For example, Archive of Our Own (AO3) has a large collection of AOT fanfictions. You can search for the most popular ones there.
The world would be in shock. The media would be filled with reports of his death. Civilians who had always seen him as a symbol of safety would feel vulnerable. There would be mass mourning in the cities he had protected.
Ryuk would probably just be amused. He is a Shinigami who has seen a lot in his existence. Fanfiction is just another strange human creation to him. He might chuckle at some of the more outlandish ideas in the fanfictions, like a character having superpowers beyond the Death Note.
Naruto could see death magic as just another form of power that can be used for good or evil. If he witnesses it being misused, he would be angry and try to stop those using it in a harmful way. He might also try to befriend those who use it for good and learn from them. He would adapt his fighting style to incorporate defenses against death magic, like using his shadow clones to test its limits without putting himself in too much danger at first.
