Well, many 'Naruto half ghoul fanfiction' stories share the theme of isolation. Naruto may feel isolated due to his half - ghoul nature, being different from everyone else in the village. Another theme is the search for a cure or understanding. He may be trying to find out how he became a half - ghoul and if there's a way to reverse it. Additionally, the theme of power corruption can be present. As Naruto gains these new and potentially dangerous powers, there's a risk that they could corrupt him, and the stories often explore how he resists or succumbs to that temptation.
The combination of two very different universes. Naruto's world is full of ninjas, chakra, and village politics. The world of ghouls is dark, with the concept of hunting and being hunted. When these two are combined in 'naruto ghoul fanfiction', it creates a whole new set of stories and possibilities.
In 'naruto ghoul school fanfiction', a recurring theme is the exploration of the unknown. Naruto is constantly exploring the mysteries of the ghoul school, like its hidden rooms and the secrets of the ghouls' powers. Another theme is the fight against prejudice. Since Naruto is different from the ghouls, he has to deal with the prejudice some ghouls have towards him, and he also has to overcome his own prejudices about the ghouls.
There could also be new characters created specifically for the fanfiction that are related to the ghoul bloodline in some way, like a family of ghoul - blooded ninjas who have their own goals and motives within the Naruto universe.
I'm not sure specifically as it's a fanfiction and can vary greatly. But it could potentially have Naruto characters like Naruto himself or Sasuke, combined with some Tokyo Ghoul characters like Kaneki. Maybe there are also some original characters created for this fanfiction.
Obviously Naruto would be the main character. For the harem, it could include Sakura. She is strong - willed and her medical skills could be interesting in relation to Naruto's ghoul nature. Hinata is also a likely candidate. Her gentle and loving nature could contrast with Naruto's more dangerous ghoul side. And then there's Tenten, who could bring her weapon - using skills into the mix.

Well, perhaps the ghoul gamer could have special abilities from the game world that they bring into the Naruto universe. They might use these unique powers to fight against the Akatsuki or help the Leaf Village in some way.
One possible plotline could be fem Naruto struggling to hide her ghoul identity in the Naruto world. She has to deal with her newfound hunger for human flesh while still trying to maintain her relationships with her friends like Sasuke and Sakura.
If Naruto had ghoul powers in fanfiction, it would change the story drastically. For one, his combat style would be very different. Ghoul powers involve using kagune, which are like weapons made from the ghoul's body. Naruto's usual ninjutsu and shadow clone jutsu would be combined with these new powers. He might be able to use his chakra to enhance his kagune attacks. Also, his relationship with his friends could change. Some might be afraid of his new, more monstrous side. And his role in the ninja world would shift as he'd have to hide his ghoul nature from those who would hunt him if they knew.
