The other Tenshi would be a main character as well. She might bring new powers or a different view of the angelic side compared to what we've seen before in the D.N. Angel series.
A third storyline could be that there is a mystery surrounding the new Tenshi. Dark is drawn into it as he tries to figure out who she really is. Along the way, they encounter various obstacles and challenges, both physical and emotional, that test their relationship and their own identities.
Based on the title, the main characters are likely 'dark' and 'another tenshi'. But without reading the fanfiction, it's hard to say if there will be other important characters that play significant roles in the story.
Well, of course, Dark is a key character. He has his own set of powers and a past that is gradually revealed in the fanfiction. Risa is also central. She's the one who forms a special bond with Dark. In many stories, their relationship is what drives the plot forward. There are also other characters from the Dn Angel universe that might make appearances, but Dark and Risa are the main focus in this type of fanfiction.
Fanfiction about D.N. Angel's Riku and Dark can explore many aspects. It might focus on their complex relationship. For example, how Riku's innocence contrasts with Dark's more mysterious and sometimes mischievous nature.

I think from 'dark meets another tenshi fanfiction', we might see a unique world - building. Since it's a fanfiction, it could take the original concepts related to 'tenshi' and add a new twist with the 'dark' element. It could show how these two elements interact in a fictional setting, like in a magical or other - worldly place.

One common theme is the exploration of forbidden love. Since Dark is a phantom thief and Riku is an ordinary girl in a sense, their relationship is often portrayed as something that goes against the norms. Another theme is self - discovery. Riku may discover more about herself through her interactions with Dark, and Dark may also learn more about his own emotions.
A human character who becomes involved with the dark angel could also be the main character. For example, a young woman who discovers the dark angel and tries to understand it, and through their interactions, she changes and so does the angel.
Start with the basic personality traits of both characters. Dark is known for his mystery and allure. The OC could have a strong sense of justice. Then, put them in different situations. For instance, in a fight scene, Dark might show his combat skills and protectiveness towards the OC. The OC, on the other hand, could use her wits to help Dark out.
