Without having read the 'the last duel original story' in detail, it's hard to say exactly. However, common elements in duel - based stories would suggest that there are at least two main characters who are at odds with each other. These characters could be knights, nobles or any individuals with a sense of pride and honor. There might also be other important figures like the person who called for the duel to be arranged, and those who have a stake in the outcome, either for personal or political reasons. Additionally, there could be characters who try to prevent the duel from taking place, perhaps out of a sense of reason or a different view of justice.
Since I don't know the exact 'the last duel original story', but generally in such stories, there would be the duelists themselves. They are likely to be from different social standings or have some sort of conflict over honor, a woman, or land. There may also be other supporting characters such as their seconds (helpers in the duel) and people in their respective social circles who might have influenced the events leading up to the duel.
