One reason could be more intense battles. For example, in a fanfiction scenario, if certain key battles like Stalingrad or Normandy had been even more fiercely fought. Maybe the Axis powers had stronger defenses or the Allies had less effective strategies initially. Another aspect could be the introduction of new and more deadly weapons earlier in the war. This could lead to higher military casualties on both sides.
One reason could be the alteration of major battles. For example, if in the fanfiction the D - Day invasion fails catastrophically, it would lead to a huge number of Allied deaths and a shift in the war's momentum towards the Axis. This would likely cause a domino effect, with more battles resulting in heavier losses as the Allies struggle to regain the upper hand.
The post - war world would be much more devastated. Economically, more military deaths would mean a greater loss of human resources. Countries would have a harder time rebuilding as there would be fewer able - bodied men (and women in some cases) to contribute to the workforce. For example, the rebuilding of Europe would be far more challenging.
The post - war world in such a fanfiction would likely be more devastated. Economically, it would take much longer to recover. With more deaths, there would be a shortage of manpower to rebuild industries and infrastructure. For example, countries like Germany and Japan that were rebuilt after the real World War 2 might struggle even more in this fictional scenario.
Maybe it's because of some dangerous environment or traps in the comic. Or maybe there's a villain causing it.
One reason could be that he feels burdened by the expectations and the weight of his newfound peacekeeping role. He might want to escape the constant pressure and find himself. Another possibility is that he discovers a new threat during the post - war reconstruction and decides to go into hiding to investigate it without causing panic. Maybe he also has some personal issues related to his relationships, like feeling estranged from his friends who have changed after the war, and he needs time alone to sort things out.
One possible reason could be political. After the war, the villages might be restructuring and Naruto, with his great power, could be seen as a threat. Another reason might be related to the secrets he knows. Maybe some powerful figures don't want him to expose certain things. Also, his Jinchuuriki status could play a role. People might still be fearful of the power within him even after the war.
One possible reason could be the trauma they both endured during the war. Ginny might be frustrated with Harry's withdrawn behavior as he tries to deal with his own demons. Maybe he's been neglecting their relationship in his post - war self - reflection.
One possible reason could be a misunderstanding over a shared resource. For example, if there's a new chakra - rich area discovered on the border between the two villages, both might claim it as their own, leading to conflict. Another reason could be due to the actions of a rogue ninja who frames one village against the other. Maybe a Leaf ninja is made to look like they attacked Sand shinobi, sparking anger and calls for war.
Maybe he has friends or relatives in America who can offer him a place of refuge. In fanfiction, it's common to create new relationships for characters, and he might be running towards those connections. Also, the wizarding community in America could have something unique to offer him, like a different approach to magic that he wants to explore.
If Ezra were to hate fanfiction, it could be because he values the purity of his own story and the official Star Wars narrative. He might see fanfiction as a distortion of what he and his friends have actually been through.
