A common theme is the exploration of their dual natures. Since Ichigo has his own powers and the female hollow ichigo has her unique hollow characteristics, fanfictions often play with how these two different yet connected aspects interact.
I'm not sure of the exact name, but there's a fanfiction where female hollow ichigo gets separated from Ichigo during a battle. It then follows her own adventure to find her way back to him, while Ichigo is also searching for her. It's a story full of action and their unspoken bond.
There could be Byakuya. He would be shocked and disappointed by female Ichigo's betrayal as he might have seen her as a promising comrade. Also, Rukia. Since she and Ichigo have a special bond, her reaction to Ichigo's betrayal would be very emotional. And then there's Aizen. He could be the one who tempted or manipulated female Ichigo into betraying, seeing her as a useful pawn in his grand schemes.
One common theme is empowerment. Female Ichigo is often depicted as strong and capable, breaking through gender barriers in the Soul Society. Another theme is self - discovery. She explores her powers and identity.
I'm not sure specifically about 'futa on female Ichigo' fanfics as they might be relatively niche and could involve inappropriate content. However, you can try searching on some large fanfic platforms like Archive of Our Own and filter the results for Ichigo - related fanfics. But be aware of the community guidelines.
One idea could be a story where Ichigo saves a female Quincy from a powerful enemy. They start off as strangers but gradually develop feelings as she recovers under his protection. They then team up to face more threats together, with their relationship growing stronger through shared battles and experiences.
There are quite a few. A lot of fanfiction writers are creative with the concept of a female Ichigo in a lemon - themed story. They might take the idea of her powers and personality and put it into a situation full of twists and turns. For example, in some, she could be in a romantic adventure with other characters from the original series, with the lemon aspect adding a bit of spice to the relationships. It's really interesting to explore these stories if you're into that kind of fan - created content.
One idea could be that the female Zanpakuto has a unique personality. For example, she could be sassy and constantly tease Ichigo while also being fiercely protective of him. In the fanfiction, she might have her own backstory, like being created from an ancient power that was sealed away for centuries until Ichigo awakened her.
The pairing is significant as it offers a fresh take on the original story. It combines two very different characters, Ichigo with his human - like qualities and Ulquiorra with her more other - worldly, often - aloof nature. This creates a contrast that can lead to engaging storylines. It also allows fans to explore gender - swapped versions of existing characters in new contexts.
Well, the relationship in such fanfiction could be full of tension. Ichigo, being the protagonist with his own set of values, and a female Ulquiorra, who might retain some of the original Ulquiorra's traits like mystery and power. Their interactions could be centered around battles, at first, but then shift towards a more emotional connection as the story progresses. Maybe she challenges his beliefs and he in turn makes her question her own nature.
