The significance of the 'te doy la vida full story' would depend on its context. In a cultural context, in Spanish - speaking cultures, such a statement is a very powerful expression of love, loyalty, or sacrifice. In a literary or cinematic context, it could be used to drive the plot forward, create conflict, or resolve a complex situation. For example, if it's a story of war, it might be a soldier's last words to his comrades or family, representing the highest form of heroism.
A'resumo novel' could be something new in the literary world. It might be a novel that is created with the intention of being easily digestible for modern readers who have less time to devote to long, complex novels. It could also be a form that combines elements of summary and novel - writing, perhaps starting with a summary of the overall concept and then delving into the story in a more traditional novel - like way, but still keeping things relatively brief and to the point.
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'm sorry, I'm not sure specifically which 'te doy la vida' story you are referring to. It could be a very specific narrative from a particular book, movie, or personal account. Without more context, it's difficult to tell the full story.
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.
