Matsushima

Matsushima receives little individual characterization outside his role on Ryuou's baseball team. The story does not establish enough about his private life or temperament to support a more detailed personality description.

Matsushima is a left-handed pitcher. That alone gives Ryuou a tactically useful alternative to its right-handed pitchers, allowing the team to change the angle and handedness presented to opposing batters.

No specific signature pitch, velocity figure or distinctive pitching style is firmly established for him.

Matsushima appears as part of Ryuou's extensive baseball roster. Ryuou is constructed as a deep, high-level program with capable players beyond the stars occupying the middle of its batting order.

His presence contributes to that pitching depth during the tournament competition surrounding Seishuu's pursuit of Koshien.

Takurou Oikawa is another prominent pitcher on Ryuou's staff, giving the school both right- and left-handed pitching options.

Tadashi Shimano is Ryuou's cleanup hitter and one of the principal offensive players supporting the team's pitchers.

Keitarou Mishima is another of Ryuou's leading hitters and plays behind the pitching staff during the school's tournament campaigns.
