There could also be characters who are initially enemies but later become allies, or vice versa, as the story progresses.

It's possible that there are multiple angels as main characters, each with their own unique type of angel wings. They could be in a conflict or cooperation situation, and the story could revolve around their relationships and how their wings play a role in their interactions, whether it's in battles or in the angelic hierarchy.
The main characters are Tessa Gray, Will Herondale, and Jem Carstairs. Tessa is the girl with special powers. Will is a Shadowhunter, he's quite complex and often moody. Jem is also a Shadowhunter, and he's very kind - hearted.
