What could be the plot of a 'Majora's Mask crossover Highschool DxD' fanfiction?

Issei could be the main character. He is already used to dealing with supernatural situations in Highschool DxD. So when faced with the strange world of Majora's Mask, he would be in a position to adapt and try to find solutions. His perverted nature might also add some comical elements as he reacts to the new and different characters in the Majora's Mask world.

One interesting concept could be the combination of the unique and often dark atmosphere of Majora's Mask with the high - energy, supernatural world of DxD. For example, the masks in Majora's Mask might have different effects when used in the DxD universe, like the Deku Mask giving a character plant - based powers in the context of the devil - filled world of DxD. Another concept could be the interaction between the characters from both. The protagonists of each might form unexpected alliances or rivalries. Maybe Issei from DxD could be intrigued by the power of the Fierce Deity Mask and try to find a way to use it for his own battles against the devils and fallen angels.

Issei would probably be one of the main characters as he is a central figure in DxD. He might be the one to first encounter elements from Majora's Mask. Link could also be a main character, bringing his skills and knowledge of the Zelda universe. Rias could be involved too, as she is an important character in DxD and her leadership skills and powers would be relevant in a crossover. And maybe Skull Kid, from Majora's Mask, could play a significant role, causing chaos with the power of Majora's Mask in the DxD world.

Well, a great plot for such a fanfiction could be a crossover with the Sonic the Hedgehog series. Sonic's speed could be a useful asset in the time - constrained world of Majora's Mask. He could help Link quickly reach different areas of Termina to complete his tasks before the moon crashes. Also, a crossover with the Metroid series might be interesting. Samus could arrive in Termina, and her advanced weaponry and suit could help in the fight against the monsters there. And perhaps Link could learn some new skills from Samus, like better ranged combat.

The plot could involve Ben's aliens having an unexpected effect on the magic in the Highschool DxD world. His alien DNA might interact with the devil or angel powers in strange ways. For instance, if he transformed into Heatblast near a magic spell, it could cause the spell to go haywire. And his presence could also disrupt the power balance between the different factions in the DxD world, leading to new alliances and rivalries.

Well, it could be about Ranma getting transferred to the Highschool DxD world. Maybe he'd get involved in the supernatural battles there, using his martial arts skills. He might team up with Issei and the others, and his unique curse could add an interesting twist to the story. For example, his transformation between male and female forms could lead to some comical or strategic situations during fights.

A plot could revolve around a spell gone wrong that merges the two worlds partially. Saber finds herself in a strange new world filled with devils, angels, and fallen angels. She might initially be confused but quickly adapt. Her presence could disrupt the balance of power in Highschool DxD. For example, the devils might see her as a threat or an opportunity to gain more power. And Saber would have to navigate this new world while trying to find a way back to her own world.

One possible interesting plot could be Sasuke arriving in the Highschool DxD world during a time of chaos. Maybe there's a new threat that neither the devils nor the other factions can handle easily. Sasuke's ninja skills and Sharingan would give him an edge in combat. He could form an alliance with Issei and his group, teaching them some ninja techniques in return for learning about the supernatural powers in their world.

Well, a cool plot might involve Issei from Highschool DxD being sent to the Naruto world. He could learn ninjutsu there and then bring some of those skills back to his own world. He might befriend Naruto and they could work together to fight a common enemy that has somehow crossed between the two worlds, like an evil group that wants to take over both the ninja world and the world of devils and angels.

The plot could involve a group of Star Wars characters finding their way into the Highschool DxD world. For example, a Jedi and a Sith could end up at the school. The students at the school would be both fascinated and confused by their lightsabers and the Force abilities. And the Star Wars characters would have to deal with the devils, angels and other supernatural beings in the DxD world. There could be battles where the Jedi's lightsaber skills are pitted against the devil's powers, and alliances could be formed in the most unexpected ways.
