There are a few niche English novels that I can recommend to you. First of all, The Catcher in the Rye was a classic novel that told the story of a teenager's growth. In addition, 1984 was a novel with a literary foundation. It described the terrifying reality of a dictatorial society. In addition," The Wife Between Us " was a mystery novel with many plot reversals. These novels were all niche but well-received works, so he could consider reading them.
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.
Oh, for sure! Death Note is considered a masterpiece in the manga world. Its unique concept and the way it unfolds make it a must-read. The characters' development and the moral dilemmas presented make it stand out from the crowd.
