Overall, the Death Note Christmas comic could be a festive spin-off that maintains the dark and mysterious tone of the original series while adding holiday elements. It might explore new aspects of the characters' interactions during the Christmas season.
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.
There are a few novels that I can recommend to you. They are all stories about being reborn as a Demon Slayer. The first was "Rebirth of the Sea of Laws, I Slay Demons in the Human World" and "Rebirth of Slaying Demons, I Actually Became a Demon Venerable?" They all focused on slaying demons and told the story of the protagonist becoming a demon slayer after his rebirth. In addition, there was also "Xu Xian's Demon-slaying Daily Life (Demonic Meow)" and "Black Moonlight of the Rebirth of the Demon Lord," which also involved the demon-slaying plot. These novels all have different styles and storylines. You can choose to read them according to your preferences.
Definitely! Demon Slayer started as a manga. It's known for its compelling plot and well-developed characters. The manga provides the foundation for the success of the anime adaptation.
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.
