Souma is a rather energetic child who has the constant drive to move forward with his cooking, mostly due to his rivalry with his father. Due to his drive to move forward Souma is willing to try odd things with food including "Grilled Squid Tentacles Dressed in Peanut Butter," though these dishes usually don't go over too well. It is because the will of Souma to try to move forward, his dishes are often considered as creative and innovative by some peers and lecturers; leading his rivalry with all the students in the Tootsuki Culinary Academy. Through all this, Souma maintains a laid back attitude towards just about everything but cooking.

Unlike most student whom used lavish ingredients, Souma didn't care about the classes of the ingredients which he claimed that it wasn't expensive ingredients, classy backgrounds, nor fancy techniques made the food better, but rather it's the wise usage and alternatives made the food interesting, and the customer's satisfaction about the food that matters. Further more, he also claimed that undefeated food in just the looks and taste in regal made him bored, which the boredom would made the chef stop improving their dishes. To eliminate such boredom, Souma continued to search for different styles of cooking around the world in order to improve his cooking skills.
