Without having read the 'the challenger light novel', it's difficult to name the main characters. But in a typical light novel, there's often a central character who drives the story forward, which in this case is the challenger.

And there could be other supporting characters like family members or comrades who add depth and complexity to the story, but until we read the novel, we can't be sure.
It could be the challenger themselves. They are usually the central focus, with their own personality, goals and dreams. Maybe they have a rival who is also a main character, constantly competing with them.
