The theme of adaptation is quite common. The OC has to adapt to the strange and often dangerous DxD world, and Ganriel helps in this process. Additionally, the theme of loyalty often plays a part. Their relationship is tested, and they show loyalty to each other in different situations, which is a key aspect in many DxD Ganriel x OC fanfics.
