Second-year regular and center of the Touou team, Wakamatsu is easily agitated and extremely loud. Being a player of notable stature, he performs commendably on the defensive, and scoops up rebounds with relative ease. He despises Aomine and frequently expresses his distaste for the latter's lackluster attitude and special treatment within the team, both out of personal jealousy and concern for their team's longevity.
