It could be about Naruto somehow getting the power of Ryuk. Maybe he finds the Death Note in his ninja world and has to deal with the moral implications of using it, like Light did in Death Note.
I'm not sure if there is such a specific 'naruto is ryuk fanfic' out there. Fanfics can be found on various fanfic websites like Archive of Our Own or Fanfiction.net, but you'd have to search specifically for it among the countless Naruto and Death Note crossovers.
A theme that often pops up is the idea of companionship in an unlikely duo. Despite their differences, in many fanfics, they develop a strange sort of bond. It could be a grudging respect or a more complex emotional connection. Also, the theme of fate is explored as they are intertwined in this strange situation due to the Death Note.
Perhaps Ryuk has to venture into a dangerous place or solve a difficult puzzle to lay his hands on the apples. The possibilities are endless based on the author's imagination.
One idea could be a story where Ryuk and Rem are forced to team up in the Shinigami realm to solve a mystery that threatens the balance between the human and Shinigami worlds. Another could be a fanfic exploring their relationship in an alternate universe where the rules of the Death Note world are slightly different.
First, you should familiarize yourself with the characters of Ryuk and Rem from the Death Note series. Know their personalities, motives, and how they interact with other characters. Then, come up with an interesting premise, like what I mentioned before. For example, a situation that brings them together in an unexpected way.
Sure. One popular 'ryuk x light fanfic' is 'The Unlikely Alliance'. It explores an alternate scenario where Ryuk and Light form a more complex relationship beyond their typical cat - and - mouse dynamic in the original story.
Ryuk doesn't have any instances of eating apples in the manga. The story doesn't feature such a detail about him and his eating habits.
Ryuk plays a crucial role in the manga. He influences the main character's actions and decisions. His interaction with the human world creates interesting storylines and conflicts.
Ryuk comics are funny because of the unique art style and the hilarious dialogues between the characters. Also, the absurd situations they get into add to the humor.
I wouldn't recommend such comics as they often contain inappropriate or adult-oriented content that may not be suitable for general consumption.
