List of Ace of Diamond characters

The following is a list of characters that appear in the baseball manga and anime, Ace of Diamond.

Characters

Eijun Sawamura

Position: Pitcher

Voiced by: Ryōta Ōsaka

Eijun Sawamura (沢村 栄純, Sawamura Eijun) is the main character. Eijun is a left-handed pitcher who has extremely erratic throwing motions. His body is naturally flexible with supple joints, allowing him to immediately change the pitch’s direction. Because Eijun has been playing baseball without proper instruction, his pitches normally change direction right before the batter hits the ball. However, this makes catching the ball difficult, as most catchers cannot predict where the ball will end up. He was initially unaware of this quirk in his throws. His knowledge about baseball is mediocre at best, but he strives to improve his skills and become Seidou's ace player.

Eijun comes from Nagano where he played baseball in his middle school. His team was below average, often making mistakes during critical moments and losing almost all matches. However, Eijun has an extremely strong spirit which, no matter how hopeless the situation got, inspired his teammates to continue playing their best. His childhood friend, Wakana, was the baseball team manager. Initially, after Eijun had been scouted by Seidou, he had planned to refuse because he wanted to keep playing with his friends in the same high school. However, his friends encouraged Eijun to go to Seidou despite their reluctant feelings because they felt as if they were holding Eijun back. Eijun eventually goes to Seidou and boldly declares that he will become the team ace.

Eijun’s strong points are his infallible spirit, bunting, infield defense, and his idiosyncratic pitches. His weaknesses are control, outfield defense, and batting. His personality is hotheaded and loudmouthed, often causing his teammates exasperation because of his stupidity. He has a rivalry/friendship with Furuya Satoru, a fellow first-year pitcher. Because his middle school team was so weak, he is extremely level-headed in critical times.

The main balls are "numbers". Because he can throw various balls of change only by changing the hand grip of the ball, he named the changing balls "numbers"

Satoru Furuya

Position: Pitcher, Left Fielder

Voiced by: Nobunaga Shimazaki

Satoru Furuya (降谷 暁, Furuya Satoru) is Eijun’s rival, Furuya is a right-handed pitcher with extremely strong fastballs and forkballs. Furuya’s pitches are so strong that no catcher in Hokkaido was able to receive them. As a result, he became alienated from his middle-school team because he was far above them in ability. After hearing about the genius catcher, Miyuki Kazuya, he applied to go to Seidou high school to play baseball with him, and immediately took respect when Miyuki easily caught his pitch. During the game of first years versus second years, Furuya jumped from the second team to the first team after only one pitch. After playing his first official game against Yokohama, Furuya became a living legend within the high school baseball world and is often described as a monster rookie.

Furuya’s strong points are his incredible pitching, outfield defense, and batting. His weaknesses are stamina and control which he refers to as "stamina roll". Furuya’s pitches are so powerful that they cause damage to his fingertips so applies nail polish to make the nails sturdier. Since he is from Hokkaido and not used to the summer heat in Tokyo, stamina becomes an issue so he cannot pitch for very long. He is stoic and unsociable with a cool demeanor and often has an expressionless face. However, his aura completely changes while pitching, once being described as "a wild wolf who wants to pitch some balls". He dislikes all other aspects of baseball besides pitching. However, he is surprisingly humble, once mentioning that he never thought himself better than Eijun. He respects Eijun to a certain point and often accompanies Eijun to do extra practice at night. Because he was an outcast in his middle school, he is happy about but unused to the Seidou upperclassmen’s friendly but bossy treatment towards him, being content when he was ordered to fetch them drinks and uncomfortable when they excessively praise him. He also likes taking advice. He gets bored easily, disliking it when he cannot play in a match, and often falls asleep when he isn’t playing, or when he wants to ignore somebody.

Kazuya Miyuki

Position: Catcher

Voiced by: Takahiro Sakurai

Kazuya Miyuki (御幸 一也, Miyuki Kazuya) is a brilliant second-year catcher with an easy going yet twisted personality to draw out the full potential from the pitchers. He is the main catcher in Seidou High School, making smart and bold gameplays. Miyuki has a great respect for Chris as a catcher, as he was on the team that Miyuki couldn't beat. He was voted as the new captain after the third years retired. When he was young, he was always harassed and bullied -to the point that he was beaten up- by his baseball teammates in his junior high, resulting in him to push others away from his personal life. It is also shown that he isn't very much close to his parents. Miyuki is perceived as manipulative and nasty personality wise. He does not open up to people or talk about his past with other people. In all actuality he is pretty closed off with himself. He is one of the few players whose room is often flocked to by other members. He is later injured during one of the plays in the semi-final game against Seiko in the Fall Tournament, but kept it to himself so he could still play finals. His injury was stated as "pulled side abdominal". He wasn't allowed later on to play at the Jingu tournament given the doctor's advise of three-week recovery period. Within that time, all he did was to look after the team and specifically comment on the sense of unity of the pitchers which he finds sickeningly well to his taste. After that 3 weeks, he started some light exercise like running and hanging out with Chris at their training center. He came back completely recovered to the team for the hellish Winter camp.

Haruichi Kominato

Position: Second Baseman

Voiced by: Natsuki Hanae

Haruichi Kominato (小湊 春市, Kominato Haruichi) is a first-year second baseman of the team, Haruichi is a naturally talented, all-rounder baseball player. Despite his small stature and frail appearance, he has pinpoint precision while batting the ball, able to hit it as wide and as far as he pleases, and control where the ball lands. He also is extremely talented at defense, able to catch a ball in the air and throw it while still floating. He is often noted to have amazing baseball sense, able to decide in a split second where to hit the ball, what to watch for, and when to steal. His ability in baseball exceeds his older brother’s, Ryousuke Kominato, who is first-string player and also a second baseman. The only thing lacking is his stamina, which he works hard on improving.

Born in the Kanagawa Prefecture, he is a very calm and quiet person, often acting as tsukkomi to Sawamura Eijun’s boke. He has a habit of saying things bluntly and often praises either Furuya or Eijun, causing them to compete against each other frequently. He plays reserve in the first-string team and occasionally feels envious of Eijun and Furuya for being able to play in a match. He is very small compared to other boys and it has been noted that he looks a bit like a girl. He is easily embarrassed, especially when praised. His relationship with his brother is slightly strained because they play the same position, but he still admires him to no end. Though reserved, he is highly ambitious and aims to take his brother’s position. When he was a child, their relationship was closer, with Ryousuke often protecting him from bullies.
