Friendship is a very common theme. Hyourinmaru and Hitsugaya have a special bond as a zanpakuto and its wielder. Fanfictions often explore how this bond deepens over time, through shared experiences and challenges. For instance, they might face a difficult enemy together and their friendship becomes stronger as a result.
Another common theme is loyalty. Hyourinmaru is loyal to Hitsugaya, and vice versa. Fanfictions can show how this loyalty is tested, like when Hitsugaya has to make a difficult decision that might put Hyourinmaru at risk, or when they are faced with external forces trying to break their bond.
Power - related themes are also prevalent. Hitsugaya's growth in power with the assistance of Hyourinmaru is a popular topic. Writers might depict how Hitsugaya learns to master new techniques or forms of his zanpakuto, and how Hyourinmaru guides him in this process.
One common theme is the bond between them. Since Hyourinmaru is Toshiro's zanpakuto spirit, fanfictions often explore the deep connection and how it affects Toshiro's growth as a shinigami.

Through these shared adventures, their relationship deepens, and they rely on each other more, which in turn leads to the development of their romantic relationship.
Another theme is the idea of them being partners in some way, either in battle or in solving problems within the Soul Society or the human world. They might have to rely on each other's strengths and overcome their differences. In many fanfictions, they start off not getting along very well but then gradually develop a deep bond.

It's really interesting to see how they change and grow closer over time.
Some fanfics explore the idea of sacrifice. Given their connection, there could be situations where one has to sacrifice for the other. For example, Toshiro might be willing to risk his own safety to protect Hyourinmaru, or vice versa. And of course, there are fanfics that blend multiple themes together, creating complex and engaging stories about their relationship.

The magical world of 'Harry Potter' has its own culture, and 'Hyourinmaru' comes from a different cultural context. Writers might explore how characters react to these differences.

Often, there can be themes related to the power dynamics. Toshiro Hitsugaya has his own power and status in the Bleach universe, and how that interacts with the OC, especially in an emotional and sometimes romantic context, can be a theme.

For example, the OC might learn more about herself through her relationship with Hitsugaya, and Hitsugaya might also grow in some aspects of his personality. Another aspect could be the theme of secrecy or forbidden love, as Hitsugaya is a significant character in the series and a relationship with an OC might not be something that is easily accepted in the Bleach world.
