Shin Kyojin no Hoshi

The story is about Hyuma Hoshi, a promising young baseball pitcher who dreams of becoming a top star like his father Ittetsu Hoshi in the professional Japanese league. His father was once a 3rd baseman until he was injured in World War II and was forced to retire. The boy would join the ever popular Giants team, and soon he realized the difficulty of managing the high expectations. From the grueling training to battling the rival Mitsuru Hanagata on the Hanshin Tigers, he would have to take out his best pitching magic to step up to the challenge. (Source: Wikipedia)

One day, at the Giants' Tamagawa ground, Egawa was throwing a simulated game in front of Manager Nagashima, when suddenly a stranger stepped into the box and mowed down Egawa's pitches. His name is Hono Mizuki. He was a player who had to move from one school to another due to his short temper getting into fights, so he never caught the eye of any scouts despite his outstanding ability. Osamu Sawada, a freelance talent scout, was asked by Manager Nagashima to investigate. He tested Mizuki first against Hyuma Hoshi, and then Mitsuru Hanagata and Hosaku Samon both had trouble hitting Mizuki's pitches, showing that he had pro-level stuff. Mizuki's competitive spirit is reignited. Mizuki and his best friend set their sights on joining the ranks of pro baseball together.
