The strongest warlord is the central figure. There may be some side characters that are crucial to the story. For instance, a group of students who form a sort of 'gang' in the school and initially oppose the warlord. As the story progresses, they may become his allies.

And there could be teachers as well, such as a strict teacher who has a hard time controlling the warlord in class, or a wise teacher who sees potential in him.
I'm not sure about the exact plot as I haven't read this novel specifically. But generally, it might be about a powerful warlord who enters a school environment.
