The plot might also develop through attempts at reconciliation. After initial hatred and conflict, there could be moments where Naruto and Sirzechs start to understand each other better. Maybe through a common enemy or a shared experience, they begin to see that their differences aren't as great as they initially thought, which would be a major turning point in the fanfiction.
The plot could develop with Naruto trying to oppose Sirzechs at every turn. He might gather his friends and allies to form a resistance against Sirzechs' plans. For instance, if Sirzechs is trying to impose a new order in a shared fictional world, Naruto would fight to protect the old ways that he believes in.
The plot could start with Naruto isolating himself from the village. He might go on a journey alone, avoiding any contact with humans. Along the way, he could encounter some non - human creatures who show him kindness, which makes him question his hatred.
One possible reason could be a clash of personalities. Naruto is from a world with its own set of values and power systems, and Sirzechs is from a different fictional universe. Maybe Naruto, in the context of the fanfiction, sees Sirzechs' power or attitude as something he dislikes. For example, if Sirzechs has a very different view on leadership compared to Naruto's idea of it, that could cause friction.
The story could develop with Naruto trying to oppose Makarov at every turn. There might be battles between them or their respective groups.
He could also feel angry. After all, he has fought for his friends and the village. To be betrayed by someone like Sirzechs would make him want to prove his innocence. He might start training even harder to show that he is not the bad guy Sirzechs is making him out to be. And he would likely try to find evidence to clear his name.
It might start by introducing a situation where Naruto and Zeus somehow cross paths. Maybe Zeus accidentally interferes in Naruto's world. Then Naruto, being the headstrong character he is, immediately takes a disliking to Zeus' overbearing presence.
The plot might start with Naruto gradually realizing certain things about his family that make him feel angry or betrayed. For example, he could find out about a hidden deal his family made that he doesn't agree with.
His character might also become more empathetic. As he glares at Sirzechs' power, he could start to understand the responsibilities that come with great power. Through interactions with Sirzechs or observing how Sirzechs uses his power, Naruto might learn to be more understanding of others with great power and the choices they have to make. This could lead to a more well - rounded Naruto who not only has physical strength but also emotional intelligence.
The plot could develop as Naruto tries to expose Ozpin's secrets. He might gather evidence against Ozpin and try to convince the RWBY characters of Ozpin's wrongdoings. This would create a lot of tension and conflict within the story.
The story could develop with Naruto leaving Konoha to find his own path. He might seek out other ninja villages or hidden places to train and become stronger on his own terms, away from the place and the family ties that he resents.
One way it could develop is if Naruto's ninja training and values from his world conflict with the more flirty and forward nature of the female demons in High School DxD. He might see their behavior as inappropriate or untrustworthy, which would fuel his 'hates women' stance.
