I don't know for sure as I haven't read it, but I assume there would be a character related to the bird, like a bird - keeper or someone who can communicate with the bird. And then there would probably be a character associated with the sword, perhaps a knight or a warrior.
Since I'm not familiar with these novels, I can only make assumptions. There could be a hero who is on a quest related to the sword, and during this quest, he meets a girl who has a special connection with the bird. These two could be the main characters. There might also be some secondary characters like the hero's comrades - in - arms who don't understand his fascination with the bird at first but later come to see its importance in the story, or the girl's family members who are either for or against her relationship with the hero.
As I haven't read the 'the bird and the sword romance novels', it's hard to say exactly. However, it's likely that there's a protagonist who is drawn to both the bird and the sword for different reasons. There might also be an antagonist who wants to use the power of the sword for evil or harm the bird. There could be other supporting characters like a wise old man who gives advice about the bird and the sword, or a young girl who helps the main character on their journey.
Since I haven't delved into these novels, I can only guess. Maybe the bird is a messenger of love or a key to unlocking a mystery related to the sword. The romance in the novels could revolve around the adventures that the characters go through while trying to understand the significance of the bird and the sword. It could also be that the sword has a curse or a blessing, and the bird is there to guide the characters through the consequences of this, and during this journey, a romantic relationship is formed.
In 'the girl and the bird story', the primary characters are the girl and the bird. The girl could be of any age, from a young child to a teenager.

Their personalities and the roles they play in the story will be crucial. The girl might be the one who initiates the contact with the bird, or the bird might be the one to approach the girl first. Their relationship will be developed as the story progresses.
