The protagonist of this work, Mihashi Ren, is a boy who hopes to become the ace pitcher of his team. In junior high school, it was believed that he could become the ace pitcher of the baseball team of the school because his grandfather was the operator of Sanxing Academy. Therefore, his teammates had a great aversion to Mihashi. As a result, not only did he have difficulty winning in three years of junior high school, but he also became cowardly, inferior and withdrawn. He even considered giving up baseball. After graduating, Mihashi decided not to go directly to the high school department of Sanxing Academy. He transferred to Saitama Prefecture to apply for a high school and entered the prefectural Nishiura High School. He wandered around the club exhibition, and then went to the baseball club with the mood of just taking a look. Unexpectedly, he was semi-forced to join by coach Maria Momoe. He was the only player in the team who had been a regular pitcher. Naturally, he became a pitcher of the baseball team of Nishiura High School. All members of the baseball team of the school are freshmen, and they have just switched from soft baseball to hard baseball. Under the guidance of catcher Abe Takaya, Mitsuhashi displayed his extremely precise ball control skills that he had trained hard for. Through game after game, rigorous training that took into account both technical and psychological aspects, and close interaction with teammates, Mitsuhashi gradually found self-confidence and trust among friends, and the whole team worked together to move towards the goal of winning the Koshien. 【STAFF】Original work: Higuchi Asahi "Raise Your Arms High" (serialized in Kodansha's monthly magazine "AFTERNOON")Director: Mizushima TsutomuSeries composition: Kuroda YosukeCharacter setting: Yoshida TakahikoGeneral animation director: Takata Akira, Taniguchi JunichiroAction animation director: Taniguchi JunichiroMusic: Hamaguchi ShiroMusic director: Kikuta HiromiAnimation production: A-1PicturesProduction: Daishin Production Committee【CAST】Mitsuhashi Ren: Yoronaga TsubasaAbe Takaya: Nakamura Yuichi Hanai Azusa: Taniyama KishoTajima Yuichiro: Shimono HiroOki Ichito: Sato YuDaieguchi Yuto: Suzuki ChihiroSuzuyama Naoji: Homura MakotoMizutani: Kaku KenichiroIzumi Kousuke: Fukuyama JunNishihiroTatsutaro: Kimura RyoheiChiyoko Shinoka: Fukuen Misato Mariya Momoe: Hayami LisaRyoro Hamada: Shichiichi Jun
