Definitely Naruto and his sister. As for the harem, Anko Mitarashi could be an interesting addition. Her wild and free - spirited nature could be intrigued by Naruto's unique personality. Kurenai Yuhi could also be part of it. Maybe she sees Naruto as a new hope for the future and her feelings gradually turn romantic. And let's not forget about Shizune. Her loyalty and kind nature could make her develop feelings for Naruto, especially with his sister being in the mix as a way to bring them closer.
Well, obviously Naruto himself would be a main character. His sister could be an original character created just for the fanfiction. In terms of the harem members, Sakura could be one. Even though she has feelings for Sasuke in the original series, in this fanfic she could see Naruto in a new light. Hinata is also a likely candidate as she already has deep feelings for Naruto. Another could be Ino, who might be drawn to Naruto's growth and newfound confidence in this alternate scenario.
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.
Obviously, Naruto himself as the lycan. Hinata could be one of the harem members as she has a long - standing crush on Naruto. Sakura might also be part of it, adding some tension due to her previous relationship with Sasuke. Then there could be Ino, who is strong - willed and could have an interesting dynamic with Naruto in this context. And Tenten, with her skills, could also be a part of the harem.
It's also possible that some non - human characters could be part of the harem. For example, some of the tailed beasts in human form (if that's possible in the context of the fanfiction). They would bring their own set of powers and a very different kind of relationship with Naruto compared to the human characters in the harem.
Well, Naruto himself is obviously a main character. As for the servants, Sakura could potentially be one. She has her own skills and a relationship with Naruto already in the original series that could be developed further in this fanfiction context. Hinata is also a likely candidate, given her long - standing feelings for Naruto.
Tenten could potentially be in the harem. She is a strong - willed and capable kunoichi. Her presence in the harem could add an element of action and adventure. Maybe she initially tries to fight against the evil Naruto but then gets drawn into his world and eventually becomes part of his harem.
There could be some original Arrancar characters created specifically for the fanfiction. For example, a young and curious Arrancar who is new to the ways of her kind. She meets Naruto and is immediately fascinated by his different appearance and abilities. And then there's a more experienced Arrancar who has seen many battles. She initially sees Naruto as a threat but then realizes his good intentions and slowly falls for him, becoming part of the harem.
In the Naruto world, Sakura could be a potential character in the harem. She's strong - willed and has her own set of skills. From the Yugioh world, Anzu could be part of it. She's kind - hearted and often supports the main characters. Another from Naruto could be Hinata, who is shy but also very loyal. And from Yugioh, Mai Valentine, as she has a bold and confident personality.
Obviously, Kankuro could be a main character as he is a well - known puppet master in Naruto. For the harem members, it could include some of the female ninjas like Temari, who has a strong personality. Another could be Sakura, as she is a main female character in the original series and could be part of an interesting dynamic with the puppet master.
Well, in addition to the ones mentioned above, Ino could be part of Naruto's harem. She's confident and has her own charm. Then there's also Temari. She's a strong - willed and powerful kunoichi from the Sand Village. Her relationship with Naruto could develop in an interesting way in a harem fanfiction. And don't forget about Karin, who has had some interactions with Naruto and could potentially be in the harem.
Well, obviously Naruto himself would be the central male character. For the female characters in the harem, Sakura could be one. She might start to see Naruto in a new light when he overcomes his blindness with such tenacity. Hinata could also be part of it. Her shy and loving nature could be a great contrast to Naruto's more outgoing and determined personality in this scenario.
