ییویوهایی ازیوما

Yuuhei was brought over to Seishuu High School by Coach Daimon to play in his first-string team. He is an excellent batter, so he is the current cleanup hitter at Seishuu. He has trouble recalling other people's names and faces, stating that he only remembers people that are worth caring for, but he apparently remembers Kou Kitamura.

[Spoiler: He has lost some of his confidence in Coach Daimon and the baseball team at the end of his first year, but seeing Kou's abilities during the practice game convinces him to stay in Seishuu after Daimon is sacked.

Yuuhei's obsession to reach Koushien is due to his guilt toward Junpei Azuma, his older brother. Junpei injured his leg, ending his rising baseball career, while saving Yuuhei from falling down a staircase. The guilt of ending his brother's career turns his desire to reach Koushien into obsession. Also, since then, Yuuhei has been very sensitive toward children who are playing around stairs and matters of when a person's recklessness effects more then themselves. Because of that, he is shown initially to be very cold and uncaring toward people around him, as he is only concerned with reaching Koushien. He gradually begins to enjoy the game more, becoming less stern on outcome and more on performance, and make friends as Junpei's happiness becomes more sincere throughout the series; turning Koushien more and more to a personal dream or goal rather then a amends to his brother. He has stated that he has romantic interests in Aoba.]
