The long-awaited digitization of the original baseball manga by Takeshi Furushiro, who worked on many of Ikki Kajiwara's originals, such as "Ore to Kaneyan", "Fukeyo! Kamikaze", and "Hiko Densetsu". Sansei Tenma Ryuhei, a Japanese Brazilian from Brazil, is extremely weak when it comes to alcohol and women, but he has an outstanding sense of pitching. He needed 10 million yen to help a woman he met by chance. Therefore, Tenma joined Keio Phoenix, a weak professional baseball team, in order to receive his contract money. He's about to face his first fight.
