Natsuhiko Kirishima

Pitcher. First-year student. Left-handed. Jersey number 1.

Ace of Osaka Youmeikan. Younger brother of Shuto Kirishima from Hyoga High School. He has an even sharper tongue than his brother and mercilessly hurls harsh words at defeated opponents. He looks down on his brother, who went to Tokyo after not being chosen by Youmei, treating him as worthless. His free-spirited nature stands out, as he claims that the ace is the most amazing guy and expresses a desire to earn a billion.
