It's hard to say whether it's popular or not. There are so many fanfictions out there. If this one manages to create a unique and engaging story by bringing Naruto's power into the Highschool DxD world, it could attract fans of both. However, if it fails to do justice to either of the original works or if it has a lot of plot holes, it won't gain much popularity. For example, if the power scaling in the fanfiction is not well - thought - out and Naruto becomes too overpowered in a way that breaks the Highschool DxD setting, it might turn off readers.
I'm not sure if it's a popular one. It could be popular if it combines the cool elements from Naruto and Highschool DxD well, like Naruto's powerful jutsus in the Highschool DxD universe. But it might not be if the writing is bad or the combination feels forced.
Naruto himself is often very popular. His energetic and determined personality makes him stand out. He can bring his ninja skills and positive attitude into the Highschool DxD setting. Also, Issei from Highschool DxD is commonly included because of his central role in his own series and his unique relationship with the devils and other supernatural beings.
It's hard to say for sure, but Alucard has the potential to be extremely powerful. His vampiric abilities like regeneration, immortality, and the ability to summon his army of familiars give him a huge edge. He can take a lot of damage and keep coming back. In a fight against Naruto's ninjutsu or the various powerful beings in the DxD world, he could be a force to be reckoned with.
Naruto is often a very popular character in these crossovers. His strong - willed nature and powerful ninja abilities make him stand out. He can bring a new level of action and adventure to the Highschool DxD setting.
Another common pairing is Sasuke and Akeno. Sasuke's brooding and powerful nature might attract Akeno, who is also quite powerful and has a bit of a mysterious side herself. They could bond over their shared power levels and a mutual understanding of what it means to be different from the norm in their respective worlds.
The crossover element itself is a huge trope. Combining the unique worlds of Naruto, Highschool DxD, and the concept of ghouls allows for all kinds of interesting scenarios. Such as when the different magic systems and ninja techniques interact. For instance, a character might try to use a jutsu in the world of Highschool DxD or combine a devil's power with a ghoul's ability.
One popular crossover might be the exploration of the unique powers. For example, Naruto's jutsu in the Highschool DxD world could create interesting scenarios. His shadow clone jutsu could be used in battles against the devils or fallen angels in the Highschool DxD setting. Another aspect could be the character relationships. Naruto's friendly and determined nature could form unique bonds with the characters in Highschool DxD like Issei. This could lead to new storylines where they team up to face common enemies or help each other grow in power.
A powerful Naruto Highschool DxD fanfiction often has a well - thought - out plot that combines the two universes seamlessly. For instance, it should explain how Naruto's abilities work in the Highschool DxD world and vice versa.
Well, in some fanfictions, Naruto's Nine - Tails power is integrated into the Highschool DxD plot. This can lead to some really intense storylines. Imagine the Nine - Tails' chakra being mistaken for some sort of extremely powerful demonic or angelic energy. It would cause a stir among all the factions in the Highschool DxD world.
There are fanfictions where Issei leaves to protect others. He might learn of a great danger that is coming and decides that the best way to keep his friends and loved ones safe is to remove himself from the situation. So, he leaves, hoping that the enemy will follow him instead of targeting those he cares about.
Issei is extremely popular in highschool dxd fanfiction. He's the main character in the original series, and fanfiction writers often like to expand on his adventures, his relationships, and his growth as a character. They might give him new powers or put him in different situations to see how he'll react.
