I don't know as I haven't read it. It could be a character named Icarus or someone related to his story.
Since I haven't read the 'flight of icarus light novel', it's difficult to say for sure. But it might have a protagonist who is inspired by Icarus. There could also be other characters like a mentor figure who tries to guide the protagonist away from the same fate as Icarus, or perhaps a villain who tries to push the protagonist into making the same mistakes. Maybe there are characters that represent different aspects of the Icarus myth, such as a character symbolizing the sun's allure or the wax that held Icarus' wings together.
Not having read the novel, I can only speculate. There could be a central character who is on a quest similar to Icarus' flight. This character might be a young and ambitious person, full of dreams and desires. There could also be side characters like a wise old man or woman who has knowledge about the dangers of the journey the main character is about to embark on. And perhaps there are some characters who are envious of the main character's courage or naivete, which could add to the complexity of the story.
