The main characters would likely be the dark angel, who is at the center of the story due to their unique nature. And then there would be the love interest. If it's a story set in a fantasy world, there could also be other supporting characters like other angels, demons who might oppose the relationship, or mortals who are affected by the dark angel's actions in the name of love. For instance, if the dark angel is protecting their love from some threat, those who are involved in that threat or those who are helped by the dark angel could also be considered important characters in the story.
Since I don't know the exact 'Dark Angel Story', it could have a main character who is the dark angel itself. There might also be some humans or other supernatural beings that interact with the dark angel, like a wise old wizard who tries to guide the dark angel towards the light, or a demon who tries to tempt the dark angel further into darkness.

In a dark angel love story, perhaps the concept of love is not as straightforward as in normal love stories. The dark angel could have powers that are both a blessing and a curse in the context of love. They might be able to protect their loved one in extraordinary ways but also bring danger because of their dark nature. It could also explore themes like sacrifice, as the dark angel may have to give up something fundamental about themselves to be with their beloved.
The main characters include Otonashi, a boy who has lost his memories, and Angel, who is in charge in the afterlife world at first. There are also other students like Yurippe who leads the group against Angel.

It really depends on the specific fanfiction. However, it could potentially include Naruto himself, as he is a central character in the Naruto universe.
