Without having read the specific 'Obito Story Ligth Novel', it's difficult to say for sure. But generally in stories related to Obito from Naruto, themes like redemption, love, and the consequences of war are common.
Naruto could be one of his allies. Naruto has this knack for seeing the good in people and would probably be willing to give Obito a chance to redeem himself. Also, Sakura, with her skills as a medic - ninja, could be an ally. She might help heal Obito if he was injured during the war and see the potential in him to be a force for good.
I think the main theme of 'death's door novel' might be the transformation that occurs at the threshold of death. This could involve not just physical death, but also the death of ideas, relationships, or old ways of life. The novel may show how characters are forced to change when they are on the verge of losing something completely, and how this change can be both terrifying and liberating.
Well, the reborn character could explore Obito's Sharingan powers in new ways. Instead of using them mainly for combat like Obito did in the original story, they could focus on using the Sharingan to understand the emotions of others. For example, they could use it to detect lies and hidden motives, which would be a unique twist on the power.
Death in novels is sometimes a tool for character development. When a character experiences the death of a loved one, it can change their personality completely. In 'A Tale of Two Cities', Sydney Carton's sacrifice, which is a form of death, shows his ultimate transformation from a rather aimless and self - loathing man to a hero. It also reflects the social unrest and the cost of revolution at that time.
Their friendship in fanfiction could be really interesting. Maybe they start as rivals but then realize they have a common goal. For example, protecting the Hidden Leaf. They could learn from each other's jutsu. Naruto could learn about space - time ninjutsu from Obito while Obito could learn about Naruto's positive attitude towards life.
Yes, there might be such fanfiction. In the Naruto fan community, fans often create various imaginative scenarios. Given the popularity of the characters Sakura and Obito, it's not unlikely that someone has written a fanfic where Sakura is Obito's sister. This could open up new storylines and character relationships, exploring different aspects of their personalities and how they interact within this new family dynamic.
Obito's influence would likely make Naruto more aware of the darker side of the ninja world. Naruto is usually very optimistic, but with Obito's guidance, he would see the hardships and betrayals that can happen. For example, Naruto might become more cautious in his trust of others.
In contemporary women's novels, the theme of death can be portrayed in various ways. Sometimes it is used to symbolize the end of a relationship or a phase in a woman's life. For example, in some novels, a character's death might represent the death of her old self, allowing her to be reborn into a stronger, more self - aware person.
It can be quite challenging. You need to approach it with sensitivity and a well-thought-out plot. Maybe build up the character and their relationships first to make the impact more meaningful.
