I'm not sure specifically as I haven't read the novel, but usually in a story about two worlds, there could be a protagonist who is a bridge between the two. Maybe a character who was born in one world but has to enter the other for some reason.
The main theme could be about the struggle between two different realms or ways of life. It might explore the challenges and growth of characters who are caught between these two worlds.
It could be about Naruto existing in two different realms or having to navigate between two contrasting aspects of his world. Maybe it's about his life as a ninja and his inner self which are like two separate worlds.
He could recommend the novel, Master Dao, Starting from Crossing Two Worlds. This novel was written by the author," The Big Boss Behind the Scenes." It was mainly about a male protagonist, Feng Chengcheng, who accidentally transmigrated to the Republic of China and discovered that he had the ability to travel between the two worlds. He used this ability to sell items between the two worlds and gradually accumulated wealth. This novel was very popular with readers. The plot was compact and very worth reading.
I'm not extremely familiar with a Upton Sinclair novel specifically titled 'Between Two Worlds'. However, Upton Sinclair was a well - known muckraking journalist and novelist. His works often focused on social and political issues of his time, such as poverty, labor exploitation, and corruption. Maybe this novel also delved into some complex human experiences, perhaps related to the struggle between different social classes or moral outlooks.
Naruto is the main character without a doubt. Besides him, characters like Hinata could be important. Hinata has deep feelings for Naruto, and if Naruto is in a strange state of being between two worlds, Hinata might play a role in bringing him back or helping him through it. Also, Pain could be a significant character if the two worlds are related to the different ideologies that Pain and Naruto represent, such as Pain's view of a world in pain and Naruto's view of a world at peace.
The Starry Sky of Two Worlds was a sci-fi/space-time travel novel written by the author, Wu Bi, in Pinyin. The story was about Su Xingfeng, a ring that could travel between two worlds. He could travel freely between the two worlds and enjoy endless resources. This novel was updated to chapter 64, and the latest chapter was the Void Spirit Gathering Array.
First, you should re - watch or re - read the original work to get a better understanding of the characters and the two worlds. Then, think about a unique concept or plot that hasn't been explored much in the original. For example, a new relationship between two side characters.
I'm not sure specifically as there could be many different plots for such a fanfic. It might involve Naruto characters being transported to the X - Men world or vice versa, and then they have to deal with the different powers, cultures and challenges in that new world.
