One common theme is friendship. Their bond as comrades is often explored, like how they rely on each other in battles. For example, in many fanfictions, Renji is there to back up Ichigo when he's facing a powerful enemy.
Often, there could be themes related to the challenges they face, both internally and externally. Internally, they might have to deal with their own emotions and insecurities. Externally, they could face reactions from their friends, family, or the community within the fictional world. Another theme could be the journey of preparing for the new life that is coming, which includes things like making a home suitable for a baby and getting the necessary supplies.

It could also include themes of protection, with Byakuya being protective of Renji during the pregnancy. And sometimes, there are themes related to the reactions of their friends and the community around them to this unusual situation.
Well, the theme of cooperation is quite common. They come from different worlds (Ichigo from the human world and Rukia and Renji from the Soul Society) and yet they have to cooperate to face threats. Also, the theme of sacrifice is there. In many fanfictions, one of them might be put in a situation where they have to sacrifice something for the others. And of course, the theme of love, not necessarily romantic love all the time, but love in the sense of caring deeply for each other and their shared values.
Well, in fanfiction terms, 'ichigo x hichigo ichigo mpreg' could be a really out - of - the - box concept.

It could be about exploring new relationship dynamics, a different take on the character's story, or just a creative exploration by the fanfiction writer.
One common theme is friendship. Their relationship often starts as a rivalry but then transitions into a deep friendship. Another theme is mutual respect. They learn to respect each other's powers and abilities.
The theme of self - discovery also appears frequently. In these fanfictions, Ichigo and Renji may discover new aspects of themselves through their relationship. For example, they might learn to be more vulnerable or understanding. And sometimes, the theme of sacrifice is there, where one character is willing to sacrifice for the other in the name of love.
A popular 'ichigo x rukia x renji fanfiction' is 'Soul Connections'. It starts with a strange phenomenon in the Soul Society that links the destinies of Ichigo, Rukia, and Renji. As the story progresses, we see how their pasts, especially Rukia and Renji's history together in the Gotei 13, influence their present relationships with Ichigo.
