It could be about Naruto characters in a high - school - like setting during a zombie apocalypse. Maybe Naruto uses his ninja skills to fight off the zombies and protect his friends. For example, his Shadow Clone Jutsu could be used to distract the zombies while he rescues someone.
Obviously Naruto would be one of the main characters. He's the protagonist of the Naruto series, so he'd likely be at the center of the action in this fanfiction too. He'd be using his ninja abilities to combat the threats in the high - school - turned - zombie - land.
Naruto's experience in dealing with tough opponents in his own world would help him in the zombie - filled Highschool of the Dead. He would be able to quickly analyze the situation, figure out the weaknesses of the zombies, and come up with effective plans. His friendship - first approach might also lead to some interesting relationships with the other characters in this new and dangerous world.
One possible aspect of such a fanfiction could be the combination of Naruto's ninja skills in the zombie - infested world of Highschool of the Dead. For example, Naruto's shadow clone jutsu could be used to distract the zombies while the characters from Highschool of the Dead search for supplies or a safe place. His ability to move quickly and stealthily like a ninja would also be a great advantage in that dangerous setting.
Well, first of all, the writers often take the unique elements from each universe. From Naruto, it's the ninjutsu, kekkei genkai, and the concept of the ninja villages. From Highschool of the Dead, it's the zombie apocalypse and the school environment. They then find ways to make these elements work together. Maybe a character with a Sharingan from Naruto can use its powers to detect zombies from afar. Also, they might use the character relationships. A Naruto character could form a team with some Highschool of the Dead survivors to face the challenges together. And they might also play with the different values of the two universes. For example, the loyalty in Naruto and the survival instinct in Highschool of the Dead.
Well, without actually reading the specific fanfiction, it's hard to say precisely. But generally, if Akatsuki is dead, it could mean that Naruto's world has lost a major source of conflict. Naruto being 'broken' might refer to him being physically or emotionally damaged in some way. Maybe he lost some important people during the fight against Akatsuki and it shattered his spirit or his ninja way.
Yes, there are likely some available. You can try searching on fanfiction websites like FanFiction.net or Archive of Our Own. Just type in the relevant keywords, and you might find some interesting stories that combine the elements of Naruto, a godlike Naruto in this case, and the Highschool of the Dead setting.
One great Naruto and Highschool of the Dead harem fanfiction is 'Naruto in the Dead World'. It combines the action - packed elements from both universes really well. The story has Naruto suddenly finding himself in the world of Highschool of the Dead, and as he tries to survive, he also forms interesting relationships with the female characters. It's a really exciting read that keeps you on the edge of your seat.
The broken nature of the fanfiction might introduce new and strange plot twists. Maybe there are alterations to the normal power systems of both series. In a typical Naruto story, chakra is the main power source, and in Highschool DxD, it's about devil powers and sacred gears. In this fanfiction, these power sources could be mixed up or modified in a way that creates a whole new dynamic for the story.
Obviously Naruto would be one of the main characters as it's in the title that he's 'broken'. And since Akatsuki is dead, they might still have an impact on the story through flashbacks or the consequences of their actions. Other characters like Sasuke could also be main characters as he's often closely related to Naruto's story.
