A prevalent theme is her struggle for identity. Being related to a well - known figure like Sirius Black, she has to find her own place in the wizarding world. This includes dealing with the prejudices some might have because of her family connection, as well as carving out her own unique path in life and magic.
One common theme is family loyalty vs. personal beliefs. Since Sirius is in Gryffindor and his sister in Slytherin, they often have different outlooks. The sister may struggle between her loyalty to her family's Slytherin values and her own emerging beliefs. For example, in some fanfictions, she might question the pure - blood supremacy her family holds dear.

One common theme is the exploration of forbidden love. Since Sirius is a Marauder and Lily's sister is related to a Gryffindor like Lily, there's often a sense of it being a relationship that has to overcome many obstacles. Another theme is friendship.

There are several common themes. The power of forgiveness is one. Given their differences, fanfictions might show how Sirius could forgive Draco for his past actions or how Draco could forgive Sirius for any preconceived notions. Another theme is the exploration of the wizarding society from their different perspectives. Draco, as a Slytherin, and Sirius, as a Gryffindor, have different views on the social hierarchy and magical traditions, and fanfictions often explore these differences.
One common theme is redemption. Sirius often goes back in time to right the wrongs he feels he's committed or to prevent tragedies from happening. For example, he might try to save someone who died in the original timeline.

He has to learn to be responsible in the relationship, and through that, he redeems himself. This can add an interesting layer to the story as it shows his growth as a character.
The theme of family also plays a big role. James's sister is part of the Potter family, and Sirius's own family situation was quite complex. Fanfictions might explore how their different family backgrounds interact and influence their relationship. For instance, Sirius might find the warmth and normalcy of the Potter family appealing, especially when compared to his own dark family history.

Sirius is always trying to protect Harry from the threats in the wizarding world.
The theme of mentorship also comes up frequently. Sirius Black, with his wealth of knowledge and experience, is often depicted as a mentor figure to Lily Luna Potter. This can involve teaching her about magic, helping her deal with the challenges of being a Potter in the wizarding world, or guiding her through moral and ethical dilemmas.
Another theme could be Sirius helping Harry deal with the difficulties at Hogwarts. This might include protecting Harry from bullies like Draco Malfoy or guiding him through the challenges of certain classes. In some fanfictions, Sirius might use his experience as a Gryffindor to inspire Harry and give him confidence.
