The manga does not shy away from the cruelty of the human body. We see Ojisan struggling to recover from matches, realizing that a technique he could pull off five years ago is now a liability. His victories are not triumphant; they are desperate, ugly, and exhausting. He wins not because he is stronger or faster, but because he knows exactly where to stand, exactly when to strike

The narrative follows a middle-aged man who finds himself in deep financial trouble after guaranteeing a friend's failed business. To settle his debt, he accepts a high-paying, secretive job offer from Seika School.
