Some popular themes could be the exploration of Kagome's darker side. Maybe her struggle with newfound powers that have a 'dark' element to them. For example, she might have to deal with powers that are a bit more aggressive or uncontrollable compared to her usual abilities.
Another theme could be the relationship between Dark Miko Kagome and other characters. It might show how her darker nature affects her interactions with friends like Inuyasha. For instance, they could be more cautious around her or she might push them away because she's afraid of hurting them with her new powers.
The theme of redemption could also be present. Kagome could be on a journey to overcome her dark side and find a balance. This could involve facing her inner demons, perhaps in the form of past traumas or mistakes that led to her becoming a Dark Miko in the first place.
Inuyasha can be really interesting in this context. His reaction to Kagome's transformation into a Dark Miko would be complex. He's used to the normal Kagome, so seeing her change might make him both worried and a bit on edge. He could try to bring her back to her old self while also being in awe of her new power.
