Rukia could be in the harem. She has a connection with Ichigo already and her strong personality might be drawn to the power and mystery of Hollow Ichigo. Orihime is also a likely candidate. Her kind and loving nature could be what makes her want to reach out to Hollow Ichigo and be part of his harem.
There might be such a fanfiction out there. However, the term 'lemon' often implies adult - themed content. If you're looking for non - adult content related to Ichigo's harem in a godlike setting, you should be more specific in your search terms and look for family - friendly fanfiction platforms. They may have stories that focus on relationships and adventures without the inappropriate elements.
Friendship is also a big theme. In many Ichigo harem fanfictions, the relationships start as friendships. For example, Ichigo could be friends with a group of people, and as the story progresses, some of those friendships turn into romantic feelings. Another theme could be the power dynamics. Given Ichigo's abilities in the original story, how he relates to those in his harem who may or may not have similar powers can create interesting plotlines. The harem members might look up to him, or they could be equals in terms of power, and this affects how their relationships develop.
One great 'bleach ichigo harem fanfiction' is 'A New Destiny for Ichigo'. It takes Ichigo on a journey where he has to deal with multiple female characters in unique ways. Another good one could be 'Ichigo's Harem Adventures' which has an interesting plot filled with action and some light - hearted moments among the characters in the harem.
One common theme is the power - up. Just like in games, Ichigo often gains new abilities or levels up, which helps him in both the gaming aspects and in winning over his harem. Another theme is the exploration of relationships. Since it's a harem genre, there are multiple love interests, and the story usually focuses on how Ichigo navigates these complex relationships.
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.
Romance is also a prevalent theme. The fanfictions often explore the romantic feelings that Ichigo and the members of his harem have for each other. It can be a slow - burn romance, with lots of blushing and shy moments, or it can be more passionate and intense, depending on the writer's style. There are also sub - themes within the romance, like jealousy among the harem members or the struggle to express true feelings.
Obviously, Ichigo is a central character. His female companions in the harem, like Orihime and Rukia, are likely to be common characters as well. They could be the ones who are pregnant or are involved in the events related to the pregnancies.
One great 'Bleach Ichigo Crossover Harem Fanfiction' is 'Ichigo's Multiverse Adventures'.
