Name: Bonda Daisuke Features: A pitcher who joined the Moguraz as Guest's fellow rookie. He was the ace and cleanup hitter for a factory team in the industrial leagues. Perhaps because of that, despite being a pitcher, his hitting stats are surprisingly decent. He is a massive geek who prioritizes buying figures and manga over his own lunch money. He dreams of establishing his own memorial hall in the future. His motto is 'Be honest with yourself.' He is the only one who can uncannily understand Domio's strange Japanese, leading him to become Domio's roommate by force. He speaks in a Kinki dialect, refers to himself as 'Oira,' and ends his sentences with '~deyansu' (or '~deyansuka' for questions). Interestingly, he was drafted lower than Guest but has a higher salary. 22 years old.

Name: Furusawa Soichiro Features: A catcher with a slightly weak arm but excellent power. He has talent, but because he suffers from frequent back pain, he constantly moves between the first and second strings. His family apparently makes totem poles. He still doesn't have a driver's license. While he has a fragile side, he is the type to step up without hesitation when he or his teammates are in a crisis. This earns him trust, though he's a bit unreliable to lean on. He isn't very good with electronic devices. 32 years old.

Name: Hatayama Norio Features: A second baseman from Hokkaido and the fastest runner on the team. The reason he's in the minor league despite his skill is due to friction with the first-string manager. His individualistic playstyle as a table-setter—refusing to steal or sacrifice bunt—was the source of the conflict. Despite his playstyle, he is actually very kind. He has an incredible sense of smell, able to guess what someone ate just by sniffing them. He loves animals so much that his dorm room is filled with them. He keeps not only dogs and cats but also exotic animals like turtles and scorpions. His father also kept many animals, which seems to be where the influence comes from. 28 years old.

Name: Domio Banderas Features: A foreign player from the Dominican Republic. He has experience in the minor leagues. He has talent but lacked the luck to make it to the Majors; he was picked up by the Propera Group before joining the Moguraz. One of the contract conditions was 'must be able to speak Japanese,' and while studying, he grew to love Japanese culture. He has a lively and bright personality. He is an exceptional hitter and extremely serious about baseball, once saying, "If you don't give it your absolute best, you'll be a loser for life." However, due to the owner's stubbornness regarding him not being a Major Leaguer, he remains in the second string. His Japanese is very broken and strange, making him hard to understand for most, but Bonda understands him perfectly. Because he hangs out with Bonda most of the time, he is naturally close with Guest as well.

Name: Mizuki Suguru Features: An outfielder with stable abilities. He has talent, but due to his insincere personality, he frequently cycles between the first and second strings. He has a cocky attitude and a sharp gaze that makes him unapproachable, but he is surprisingly a loyal, hot-blooded guy. He loves B-movies and owns quite a few books on baseball. His appearance at Koshien was what motivated him to become a pro. 25 years old.

Name: Kuragari Hitoshi Features: A man who has faced much adversity and is extremely poor. He is fragile, timid, and lacks confidence, but he has a good heart. He is a father of a son and a daughter (Son: Akira, Daughter: Hideko). Though a third baseman, he is a switch-hitter and a utility player capable of playing multiple positions, with defense being his specialty. He lives in a small shack on the Moguraz grounds near the dormitory. He siphons gas, water, and electricity from the dorm, living frugally so he only has to pay rent. His goal is to be the 'Best Father in Japan' for his children. He uses polite speech with everyone. 34 years old.

Name: Nonomura Kozo Features: The second-string manager and former ace pitcher of the Moguraz. He is experienced and known for his ability to lead during unexpected situations. He has a stubborn personality but isn't so rigid that he won't listen to other opinions. 56 years old.

Name: Isoda Shuichi Features: The second-string coach of the Moguraz. He also serves as the dormitory manager. For reasons unknown, he is still single; the fact that he has a son and daughter suggests he is divorced. He has a hands-off approach, leaving practice to the players' discretion. Judging by his ability to evaluate game content and his coaching skills, he seems to value player autonomy. Contrary to his stiff and stern appearance, he is surprisingly kind. Like Bonda, he is a geek and often bonds over shared interests. 46 years old.

Features: The first-string coach of the Moguraz. His full name has not been revealed. He has a passion for baseball, but knows little else; baseball is his entire life. He is cold and analytical, with a knack for spotting potential, often suggesting changes to pitching forms or ordering practice for sub-positions. 43 years old.
