Yoshinori Yanagisawa is an economics professor at International Cultural University. He keeps to the right of the sidewalk when he walks, and doesn't cross the street any place other than a crosswalk. He loves low-cost, great tasting dried fish, and will walk to the end of the earth to get one. No matter what has happened to him during his day, he always goes to bed at 9 p.m.

Today, Yoshinori's day began with an argument with his daughter Setsuko about whether to cross the street at a crosswalk or not. Mrs. Yanagisawa just looked on while both Yoshinori and Setsuko refused to budge from their positions long enough to listen to the other. Setsuko couldn't take anymore, so she got up and left right in the middle of the argument. Even after his heated debate with his daughter, Yoshinori still walked on the right side of the sidewalk, and used the crosswalk on the way to campus.
