A fanfiction could blend the two in terms of the themes. The friendship and loyalty seen in Harry Potter could be paralleled in the group dynamics in Highschool of the Dead. Also, the power struggles in the wizarding world could be compared to the struggle for leadership and resources in the zombie - filled high school. It could be a really interesting exploration of two very different but equally engaging fictional worlds.
It could be really interesting. Maybe the magic from Harry Potter could be introduced into the world of Highschool DxD. For example, the wizards could use their spells in the battles that happen in Highschool DxD. The characters from both universes might interact in unexpected ways. Harry Potter characters could be shocked by the different types of beings in Highschool DxD, while the characters from Highschool DxD could be fascinated by the magic of Harry Potter.
Well, it might be a very dark fanfiction. Since 'Love Me Dead' sounds rather gloomy. In the story, the magic from Harry Potter and the supernatural elements of Twilight could be combined in a twisted way. The characters could be constantly struggling between their normal feelings and this 'Love Me Dead' influence. Like Harry Potter might find his magic being affected by it and the Twilight vampires might find their thirst for blood changing because of it.
Well, one possible plot could be that Naruto's ninja skills come in handy in the zombie - infested Highschool of the Dead world. He might team up with Rika to protect their classmates. Maybe Naruto uses his shadow clone jutsu to create distractions while Rika, with her own unique skills (which could be developed specifically for this fanfic), helps to find supplies and safe zones. They could also face challenges within the group, like dealing with classmates who are too scared or those who try to take advantage of the situation.
One possible plot could be that Naruto, with his ninja skills and indomitable spirit, finds himself in the world of Highschool of the Dead. He teams up with Saya, who is known for her intelligence and combat skills in that universe. They could be on a mission to find a cure for the zombie outbreak. Naruto's shadow clone jutsu would be very useful in distracting the zombies while Saya uses her firearm skills to take them out from a distance.
It could be a very different take on the Harry Potter universe. Without emotions, the characters might seem robotic. For example, Harry's fight against Voldemort could be more like a strategic battle without the emotional drive of revenge or protecting his friends. It would be a cold, calculated world where magic is just a tool and not something that is tied to the characters' feelings.
It would probably be really wild. Picture Harry Potter in the Highschool DxD world with all its unique characters and concepts. Maybe Harry would have to deal with the devilish and angelic beings in a whole new way, using his magic skills from the Potterverse.
Well, it could be about Harry and his friends having to journey into the Land of the Dead to retrieve a powerful magical artifact. Maybe they need it to defeat a new dark wizard who is using the power of the dead to gain strength.
One possibility could be the magic systems interacting. In Harry Potter, magic is more about spells and potions, while in Highschool DxD, it's more about the power of Devils and Angels. If they were in a crossover, perhaps the characters from Highschool DxD could learn the structured magic of Harry Potter, like Hermione teaching Issei how to brew a Polyjuice Potion. This would create some really fun and chaotic situations.
Well, in this 'Harry Potter King of the Dead' fanfiction, it could be that Harry Potter is transported to a realm where the dead are ruled. He then has to navigate this new world, facing challenges that are unique to this death - centered place. He might encounter dead wizards and witches from the past and has to prove himself as the 'King of the Dead' perhaps by solving ancient magical mysteries or battles against dark forces that lurk in this realm.
The magic system in Harry Potter could be integrated by having characters from Highschool DxD learn spells. For example, Issei could learn the Wingardium Leviosa spell to lift objects during battle, giving him an unexpected advantage. The Portkey concept could also be used to transport characters between the two worlds quickly.
