Another excellent one is 'Beyond the Notebook'. It explores an alternate timeline where Light doesn't find the Death Note right away. It shows how different the story could have been and how the characters' lives would have unfolded without the immediate influence of the Death Note. The author does a great job of building up this new narrative.
Another great one is 'Beyond the Notebook'. It explores what could happen if the Death Note had different rules and powers. It's really interesting as it twists the original concepts in a creative manner. There are a lot of unexpected plot twists that keep you hooked from start to finish.
One great 'Naruto and Death Note' fanfiction is 'The Shinobi's Death Note'. It combines the unique power systems of both universes really well. The story has Naruto stumbling upon the Death Note and trying to figure out how to use it in a way that aligns with his ninja values.
One great 'Death Note Male OC Fanfiction' is 'The Unseen Hand'. It has a really interesting male original character who has the ability to predict minor events related to the Death Note killings. This adds a new layer of mystery to the story.
One great 'Death Note' Mello and Lemon fanfiction is 'The Unlikely Bond'. It explores a unique relationship between them that goes beyond the typical dynamics in the original series. The story is well - written, with detailed characterizations that make you feel like you're truly seeing a new side of Mello and Lemon.
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.
Misa would likely be excited. She is a big fan of Light and the whole 'Kira' concept. In fanfiction, if there are scenarios where she has more power or a closer relationship with Light, she would be all for it. However, she might also get jealous if there are other female characters getting too close to Light in the fanfictions.
I really like 'Near and Mello: A New Beginning'. In this fanfic, it starts with them having to re - evaluate their views of each other after the events in the original 'Death Note' story. It's interesting to see how they slowly build a new kind of relationship, not just as rivals but as something more like partners in a strange new world order. It's a short but engaging read.
