Leon is a passionate, hot-blooded young teenager. He often slacks off from studying and baseball practice; however, his baseball skills were never diminished due to his status as Ultimate Baseball Star. Leon is also very determined to change his current title to Ultimate Musician. In Leon's Free Time sequence, the reason for that determination is revealed: to win a heart of a girl that he happened to meet at the hair salon. Later, Leon himself states that he somewhat missed playing baseball; something that he used to do every day since he was young. He even invited Makoto to play baseball with him once they get out of their current situation.
