What are some interesting plot ideas in 'Death Note Ryuk x Light' fanfiction?

Another interesting plot might be Ryuk trying to save Light from his own downfall. As Light gets deeper into his plans and faces more challenges, Ryuk, who has a unique understanding of the situation, could attempt to guide Light in a different direction to avoid his ultimate demise.

One aspect that could be explored in such fanfictions is the idea of dependence. Light depends on Ryuk for the use of the Death Note, at least in terms of understanding its full capabilities. Ryuk, on the other hand, depends on Light for entertainment. This mutual need could be the basis for a deeper, more emotional connection in the context of yaoi fanfiction, where feelings of love or at least a strong bond could develop in unexpected ways.

Isolation is also a common theme. Light is isolated in his grand plan to create a new world, and Ryuk is isolated in his existence as a Shinigami. Their relationship in fanfiction can be a way to break that isolation for both of them. It can be a connection that neither expected but that becomes essential to their characters' development.

You could also try FanFiction.net. Although it has a wide range of content, you can use the search function to find 'Death Note' fanfiction involving Ryuk and Light. Then, carefully read the summaries and reviews to ensure it's not lemon - themed. Some fanfics might focus on their unique relationship in a more platonic or plot - driven way, like exploring how Ryuk's presence affects Light's actions in the story from a different perspective.

In 'Death Note Ryuk x Rem Fanfiction', a frequent theme is the contrast between their loyalties. Ryuk doesn't really have a strong loyalty to Light, he's just entertained by him. But Rem is extremely loyal to Misa. This contrast often leads to interesting scenarios where they either clash or come to some sort of understanding. Also, the theme of their different views on the power of the Death Note is common. Ryuk sees it as a source of amusement, while Rem is more cautious about its use due to her love for Misa.

A crossover with 'Fullmetal Alchemist' could also be fascinating. Maybe Edward Elric discovers the Death Note in his search for the Philosopher's Stone. He would be conflicted because his moral code as an alchemist goes against using such a tool for killing, yet the power it offers could potentially help him achieve his goals in a different way.

One idea could be that it's an alternate universe where Light's actions in the Death Note world have led to some strange consequence that results in a pregnancy - like situation for him, but it's more of a metaphor for a new 'life' or change coming into his world. For example, he could be 'pregnant' with a new idea or plan that will change the power dynamics in the Kira case.

One idea could be a story where Light and Misa try to navigate their relationship outside of the Kira case. Maybe they go on a trip together and have to deal with normal couple problems while still being on guard against possible pursuers who might suspect their true identities.

One idea could be that Beat discovers a hidden power within Note that changes their relationship dynamic. For example, Note might have the ability to manipulate sound waves in a unique way that helps Beat in a music battle.

There might be a fanfiction where L discovers Light's identity as Kira much earlier, but instead of immediately trying to expose him, he decides to study Light's motives and actions more closely. This could involve some intense psychological battles between them as L tries to figure out what makes Light tick and Light tries to outwit L in a different way.
