One interesting plot idea could be a pre - apocalypse story within the Highschool of the Dead universe. Maybe showing how the relationships between the main characters were developing before the zombies showed up. For example, Rei and Takashi's friendship turning into something more complex as they dealt with normal high school drama.
A cool plot idea might also be a time - skip fanfic. After a few years of surviving in the zombie - infested world, the group has changed a lot. Some have become more hardened, while others are starting to lose hope. The story could explore how they deal with new threats, like a group of raiders, and also how they try to rebuild some form of civilization within the ruins of their town.
Another plot could be a side story focusing on a minor character. Say, we follow the journey of a teacher who was initially overlooked. This teacher could be trying to gather supplies and students who were left behind in a different part of the school during the chaos. It would give a different perspective on the whole apocalypse situation in the school.
One idea could be a crossover with a superhero universe. The students from 'Highschool of the Dead' could gain superpowers and have to use them to fight the zombies while also dealing with the typical superhero drama like secret identities and rivalries. Another could be a crossover with a post - apocalyptic fantasy world. They might encounter magical creatures in the midst of the zombie apocalypse and have to figure out how to co - exist or fight them. Or a crossover with a sci - fi space adventure, where they find a way to escape the zombie - infested Earth in a spaceship and face new threats in space.
One idea could be a crossover where Naruto characters are suddenly thrown into the Highschool of the Dead world. They could use their ninja skills to fight off the zombies. For example, Naruto could use his shadow clones to distract the zombies while others find a safe place. Another plot could involve a Highschool of the Dead character getting ninjutsu powers and having to learn to control them like a Naruto character. Maybe they accidentally use a fire - style jutsu in the middle of the school, causing chaos among the survivors and the zombies.
One idea could be to explore the backstories of the minor characters in more depth. For example, the story could focus on a side character's journey before the zombie apocalypse and how they've changed since then. Another plot could be a survival story that takes place in a different location than the original, like an isolated island where they have to deal with not only zombies but also limited resources.
One idea could be that Naruto's immortality gives him unique abilities in the high - school - during - the - zombie - apocalypse setting. For example, he could use his shadow clones to distract the zombies while he and his friends find a safe haven. Another plot idea might be that Naruto discovers a way to cure the zombie virus using his chakra, but he has to face many challenges and enemies who want to use the cure for their own evil purposes.
A plot idea could be that a group of students suddenly develop Rinnegan powers during a zombie outbreak in their high school. They must then figure out how to use these powers to not only survive but also find a cure. Another idea is that a Naruto - like character from another dimension arrives in the Highschool of the Dead world with Rinnegan and tries to teach the survivors ninjutsu to fight the zombies.
One idea could be a fanfic where Shizuka uses her medical knowledge to create a makeshift hospital in the post - apocalyptic world. This could show her as a strong and resourceful character, and how she interacts with other survivors who come to her for help.
Yes, there could be. For example, it might combine the unique ninja abilities from Naruto with the high - tension survival situations in Highschool of the Dead. Maybe Naruto characters have to use their jutsus to fight off zombies in a high school setting.
One idea could be creating an OC who is a master hacker. In the chaos of the 'Highschool of the Dead' world, this OC could use their skills to hack into security systems, gather information about the zombie hordes or even try to find a possible cure. For example, they might hack into a military base's communication system to see if there are any rescue operations planned.
One plot idea could be that Saeko and Takashi are separated from the group during a zombie attack. They have to rely on each other's skills to survive. Saeko's sword - fighting skills and Takashi's leadership come together as they find a safe haven. Along the way, they might discover a hidden place filled with supplies and clues about the origin of the zombie outbreak.
One idea could be a group of survivors who find an abandoned military base and have to deal with both the undead and the secrets it holds. Another could be a story focused on a character who has a special ability to communicate with animals in the post - apocalyptic world, and how that helps the group survive. Maybe a fanfic about a community that tries to build a self - sustainable farm while fending off walkers.
