Without having read the 'free as the wind novel', it's difficult to say exactly who the main characters are. However, it's possible that there is a protagonist who has a special connection to the wind, perhaps a magical or spiritual connection. There might also be antagonists who try to restrict this character's freedom, creating conflict in the story.
Since we don't have any information about the 'free as the wind novel' itself, it could have a main character who is a rebel. This rebel might be fighting against a repressive system and is inspired by the freedom of the wind. There could also be a sidekick character who supports the main character in their journey towards freedom.
There might be a wise old mentor who guides the protagonist in their journey related to the wind sword. And perhaps an antagonist who wants the power of the wind sword for his own evil purposes.
