He often uses harsh words, but they are intended to stimulate player growth. Characterized by his bowl cut and stubble, he radiates a somewhat unhealthy aura. He always prioritizes data and theory, sometimes rejecting traditional training methods for the sake of victory. He is depicted as one of the most intellectual characters in the series.
