Definitely Hinata. Her love for Naruto is well - known, and in a post - apocalyptic world like Dead Rising, she would be by his side. Sakura could also join the harem. She has a complex relationship with Naruto and this new setting could change things. Then there's Temari. She's strong and independent, and in this new world, she might find herself drawn to Naruto. Karin, with her unique abilities, could also be part of the group of female characters in the harem.
One plot idea could be that Naruto finds himself in a post - apocalyptic world of Dead Rising. He starts to gather survivors and among them are a group of girls who develop feelings for him. Maybe they have to fight off hordes of zombies together while Naruto tries to keep everyone safe. Another idea is that Naruto has some unique abilities in this new world that draw the attention of different female characters, and they form a harem as they rely on him for survival.
In this Naruto - Dead Rising fanfiction, Naruto could team up with some of the survivors in the Dead Rising world. They would be initially skeptical of his strange powers but soon realize his value. Naruto could teach them some of his ninja training techniques to help them better defend themselves against the zombies. And in turn, they could teach him about the unique aspects of the Dead Rising world, like how to find and use the best weapons against the undead.
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.
A good one has to blend the two universes seamlessly. For example, the powers from Naruto like jutsus should fit into the world of Highschool of the Dead without feeling forced. Also, the harem aspect should be developed in a natural way. The female characters' personalities from both Naruto and Highschool of the Dead need to be respected and their relationships with Naruto should progress realistically.
Sakura could be one of the members. In the original Naruto series, she has a connection with Naruto. In this fanfiction, in the high school setting, she could continue to be drawn to Naruto's growth and strength. Another could be Rei from 'High School of the Dead'. She is a strong - willed character, and Naruto's heroic nature might attract her. And then there could be Tenten. Her weapon skills could be useful in the zombie - infested high school, and she might develop feelings for Naruto as they fight together.
In this fanfic, Naruto and Amber could have different goals at first. Naruto might be on a quest to find a way back to his own world, while Amber is trying to rescue her family or something. However, as they face the common enemy of the zombies, they realize that they need to work together. Naruto's chakra - based abilities could be a huge asset in dealing with the powerful zombies. For example, his Rasengan could be used to take out large groups of zombies at once. Amber, on the other hand, could be the one with the knowledge of the layout of the area in Dead Rising 2, guiding Naruto through the dangerous streets and buildings.
Some less obvious choices could be Kurenai. Her experience and calm nature could contrast well with Naruto's more energetic personality. Also, Konan could be included. Her skills and backstory could make for an interesting relationship with Naruto within the context of a harem, and she has a certain allure that would fit in well.
One idea could be Naruto traveling to different dimensions where he meets alternate versions of female characters and they all form a sort of harem around him. Another could be that after a powerful jutsu, Naruto is transported to a realm where the rules of life and death are different, and he has to deal with female characters who have their own motives regarding his presence in this new world.
