Ryō is normally very slow, lazy and gloomy. His general demeanor lacks any sort of interest on what is going on around him, but he remains attentive. He is not shy to speak his own mind or criticize. Ryō has a much more passionate personality that only emerges once he wears his signature bandana. This new demeanor is much bolder, wilder and untamed, akin to a wild beast, fittingly called his "Berserk Mode". Ryō considers all kitchens to be a battlefield with the food a chef makes.
