I'm not entirely sure specifically what a 'doppio senso novel' is. It could potentially be a novel that has a double meaning or two different levels of interpretation. But without more context, it's hard to be definite.
Sorry, as I'm not sure exactly what a 'doppio senso novel' is, I can't recommend any. But if it's about novels with dual meanings, you could start with some works by Franz Kafka like 'The Metamorphosis'. It has a literal story of a man turning into an insect, but can also be seen as a commentary on alienation and the human condition.
The 'Scythe' novel is set in a future world where death by natural causes has been conquered. Scythes are people tasked with the job of culling the population to maintain balance. It's a thought - provoking story about mortality, power, and ethics.
The theme of 'Scythe' could be mortality and the power of life and death. It explores how the concept of immortality changes human behavior and values.
Perhaps it was a weapon created by a rogue ninja with unique powers. And for some reason, it found its way to Naruto in Wave. It might also be a weapon that was enchanted by a sorcerer long ago and has special abilities that Naruto will discover as he uses it.
He might use a scythe with a chakra - infused blade. This would give it an extra edge (literally) in combat, allowing it to cut through tougher materials. The scythe could also have some sort of sealing mechanism on it, similar to his kunai, so he could store small items or even chakra - based attacks within it for surprise strikes.
The origin could be some ancient, long - forgotten magic. Maybe it was created by a powerful and now - extinct clan. They might have imbued it with a spirit or some form of intelligence for a specific purpose, like protecting a hidden treasure or an important location.
One potential character could be Sasuke. Imagine in a dark, alternate universe fanfic where Sasuke, instead of using his sword, wields a scythe. It could be a symbol of his more menacing and reclusive nature. He might use it with his Sharingan abilities, making his strikes not only powerful but also unpredictable as he can anticipate his opponents' moves.
The scythe often has a back story related to farming and harvesting in many cultures. It was a crucial tool for reaping crops. In some mythologies, it might be associated with figures like the Grim Reaper, symbolizing death and the end of life's cycle. But originally, its main use was in agriculture to cut down grains efficiently.
