Karin and Yuzu, Ichigo's sisters, could be part of the harem in a non - traditional way. Their connection to Ichigo and their own budding spiritual powers could create some interesting family - like relationships within the harem. Uryu could also be there, his Quincy abilities providing a different perspective. And a new original character, an arrancar with a mysterious past, could be added to the harem to stir things up.
Tatsuki could be included in the harem. She's Ichigo's friend from school and her tough - as - nails attitude would contrast with some of the other more spiritual characters. Yoruichi could also be a part of it. Her experience and powerful cat - form abilities would make her a valuable and interesting addition to the harem. And let's not forget Chad. He could be like a protector of the harem, with his own brute strength.
Rukia could be one of the characters in the harem. She has a long - standing relationship with Ichigo and her own strong spiritual powers. Orihime could also be part of it. Her kind - hearted nature and unique abilities would add depth to the harem dynamic. Another potential character could be Neliel. As an arrancar herself, she could have an interesting relationship with arrancar Ichigo.
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.
Obviously, Ichigo would be one of the main characters. And then, there would be the Arrancar characters who are part of the harem. But without more information about the specific fanfiction, it's difficult to name the exact Arrancar characters involved.
Rukia could be one of the characters. Since she has a deep connection with Ichigo already in the original series, it would be easy to develop a more romantic aspect in the harem setting. Orihime is also a likely candidate, as she has strong feelings for Ichigo. And from other animes, a character like Saber from 'Fate/stay night' could be interesting. Her noble and powerful nature would contrast with Ichigo's more rough - around - the - edges personality.
Obviously, Ichigo himself is a central character. From Fairy Tail, characters like Lucy could be part of the harem. Her kind and adventurous nature might be attracted to Ichigo's strength and sense of duty. Erza could also be there, with her strong - willed and powerful personality being drawn to Ichigo's unique abilities. And Wendy, given her gentle and healing nature, might also find herself interested in Ichigo.
A possible plot could involve Ichigo being in a situation where he has to choose between his arrancar nature and his relationships with the harem. His arrancar side might be drawn to power and chaos, but his love for the harem makes him want to stay on a more moral path. This internal struggle could drive the story forward and also affect his relationships within the harem.
Inoue Orihime from Bleach itself could be a part of the harem. Since she already has feelings for Ichigo in the original series, it would be a natural fit. Also, Saber from Fate/Stay Night. Her noble and powerful nature would contrast well with Ichigo's more rough - around - the - edges style. Another could be Rem from Re:Zero. Her loyalty and love - stricken nature could add an interesting dynamic to the harem as she falls for Ichigo.
I'm not entirely sure as it's a fanfiction, but generally in an Ichigo and Arrancar harem scenario, it might involve Ichigo having some sort of relationship with multiple Arrancar characters. However, without reading the specific fanfiction, it's hard to say exactly what the plot is.
In a crossover with Naruto, Sakura could be a potential member. She's strong - willed and might be attracted to Ichigo's power. From Fairy Tail, Erza could also be part of the harem. Her no - nonsense attitude and strength would make for an interesting dynamic with Ichigo. And from One Piece, Nami could be in the harem. Her intelligence and love for treasure might draw her to Ichigo.
Definitely Hinata. She already has strong feelings for Naruto in the original Naruto series. Sakura could also be part of it as she has a long - standing relationship with Naruto. From other series, if we're doing a crossover, Erza from Fairy Tail could be an interesting addition. She's strong, independent, and would make for an interesting dynamic in a harem situation with Naruto. Also, Rukia from Bleach could be another. She has a cool and collected personality which would contrast with Naruto's more exuberant nature.
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.
