Diamond no Ace (ダイヤのA), or, in English, Ace of Diamondnote Exactly as written on screen. A more natural translation would be "Ace of the Diamond", which is used for the Crunchyroll simulcast. is a shōnen baseball manga written and illustrated by Yūji Terajima and published by Kodansha. It has been serialized by Weekly Shōnen Magazine since 2006. In 2008, Ace of Diamond received the Shogakukan Manga Awards for the shōnen category. In 2010, it won the Kodansha Manga Award for best shōnen manga.Sawamura Eijun is pitcher from rural school Akagi Junior High, where the school's baseball team was fairly badnote To be exact, they never won. Despite this, Sawamura thoroughly enjoyed playing with his teammates, and was dead set on entering high school with them and continuing their journey to Koushien there. However, he's scouted by a manager from an elite private school in Tokyo. After some deliberation and encouragement from his junior high teammates, he decides to carry their dreams with him as he moves to Tokyo to join Seidou High School's powerhouse baseball team. Unfortunately for him though, what he finds there isn't quite what he expected...An Anime adaptation by Madhouse and Production I.G has premiered as part of the fall season.
This series contains examples of:
The Ace: Seido has no "true" ace, and the ace number is the ultimate goal for Tanba, Furuya, Sawamura, and Kawakami; as they are the four first-string pitchers, and the ultimate premise of the series. Tanba is chosen as the ace, but sustains an injury before the summer tournament, when jerseys are handed out, he is given the ace number, thus making him the ace. The reporters mention this as the main reason why Seidou lost against Inashiro on the road to Koshien.
After the loss against Inashiro and the third years graduated, jerseys were redistributed to the first string players, Sawamura was given 18, Kawakami stayed at 10, and Furuya was given the ace number, 1.
In terms of batting, Haruichi boasts the highest avg on the team at .571 (meaning he hits the ball 57.1% of the time), the next closest to him is Shirasu with .333 (33.3%, hits a third of the time).
Affectionate Nickname: Sawamura was called "Ei-chan" by his Junior High team and he calls Haruichi "Harucchi" (which basically means "Little Haru-chan") fondly.
Big Brother Instinct: Ryousuke was very close to Haruichi when they were younger and protected him from bullies, however, their relationship became estranged when Haruichi took up baseball and they played the same position. Currently, they are still estranged, but Ryousuke shows that he still cares and looks out for Haruichi, just not as openly as before.
Big Brother Worship: Haruichi really admired Ryousuke since they were little kids. In fact, it's his worship of him that makes him decide to use wooden bats, in order to catch up to Ryousuke, and have Ryousuke acknowledge him. He does, in their decisive match against Inashiro Tech.
Awesomeness by Analysis: Miyuki usually uses this to strike out the batters, then uses it again to score when at bat.
Back Story: To the date three of them has been released as extras: Miyuki's, Kuramochi's and Ryousuke's.
Confusion Fu: Sawamura's specialty. His pitches lack the speed and control of most of the other pitchers, but because of his unique pitching style, the trajectory of his pitches shift, even if he uses the same pitch over and over. And the shift can be subtle or wild, depending on how hard he pitches. Thanks to the lower speed of his pitches, he's easier to get hits off of than, say, Furuya, but because it's completely impossible to predict the ball's trajectory shifts, it's damn near impossible to get a decisive hit off of him. This makes him harder to score off of than the other pitchers, despite them being harder to hit off of.
Crippling the Competition: One of Teikou's players tries to do this to Miyuki. It kicks him back in the face when Miyuki, despite being hurt, ends the game with a very epic home-run.
Furuya:I've always thought about this, but... Miyuki-senpai, is your personality really that nasty?
Miyuki:Haha. Well said!
Fragile Speedster: Furuya, who has the fastest fastball of all of Seidou's pitchers, has weak nails and poor stamina, even worse in Summer, as he hails from Hokkaido.
Haruichi is an all-around amazing baseball player, being able to pick where and how far he hits a ball at bat, can jump up and catch a ball and throw it while still in air, and has incredible speed, all in all, his skills surpass his first-string, third year, older brother, Ryousuke; but like Furuya, he lacks in stamina.
Game-Breaking Injury: Chris's shoulder, which he's trying to rehab. Also his former teammate from middle school Zaizen suffer a leg injury.
Right when Tanba solidifies his spot as The Ace, he gets hit in the jaw from a wild pitch during a game, the game was called as a result from the injury and he was out for several months with a fractured jaw. As a result from the injury and recovery process, Tanba was benched for the first few games of the summer tournament.
Basically find any two players on the team that are close and they fit this.
Heroic BSOD: Sawamura suffers one after he hits one of Inashiro's players in the 9th inning. It's made even worse when he gets relieved by Kawakami and he blows the save.
Sawamura also suffers this during the Seidou vs Yakushi game, Raichi hit a homerun off him after Sawamura vowed not to let Kataoka down, he manages to stay calm, but is mentally crushed and is then relieved by Kawakami when he allows two more runners on base. Kawakami also suffers from this in the same game while on the mound, due to the memory of Raichi's homerun scored off of Sawamura replaying mind, affecting his usual control.
Hot-Blooded: Sawamura, even by manga and anime standards.
I Can Still Fight: Miyuki decides to hide his injury from the team and play against Yakushi. Even after they realize he asks the coach to let him keep playing.
Important Haircut: Tanba, the Ace of Seidou as punishment for failing the challenge imposed by his teammates. Though he didn't fail, he was injured by a dead ball before he could properly attempt challenge:
Irony: Sawamura initially wanted to form a battery with Miyuki upon arriving at Seidou, and he was borderline furious that he was to form a battery with Chris, however, after bonding with Chris, Sawamura wants to keep the battery with Chris alive and is actually upset that he has to partner up with the person he originally wanted to be his catcher; he slowly comes to accept Miyuki, however, but still desires to be in a battery with Chris.
It takes him a while but he starts remembering more frequently that he actually only came to Seidou because Miyuki left such a big impression.
It's Personal: The current Tournament gets even more dramatic when the team learns of Kataoka leaving if they don't make it to Koushien.
The Napoleon: The Kominato brothers are the shortest two players on the team, Haruichi being marginally taller than Ryousuke, both are below average height for boys their age and they are 164cm or roughly 5'4 (Haruichi) and 162cm or 5'3 (Ryousuke) in comparison to the rest of their team who are in the 170+ centimeter range.
The Nicknamer: Sawamura comes up with a nickname for many members of the team; such as:
Haruichi - "Harucchi", Ryousuke - "Nii-san", Jun - "Spitz-sempai" and "Beard-sempai", Tetsu - "Leader", Kataoka - "Coach Shades" and "Boss"
Passing the Torch: With the third years graduating, a lot of first and second years took over the empty positions, the most prominent being Haruichi taking his brother's position, number, and batting spot before moving into the clean-up batters.
Tanba's ace number is passed to Furuya.
Leadership is passed from Tetsu to Miyuki along with his position as clean-up batter.
Red Oni, Blue Oni: In the anime, Seidou and their opposing team are depicted with red or blue coloring, it's used to show both state of mind of the individual showcased players and the team's personalities in comparison to the other.
It was best shown during Raichi's second at-bat against Eijun; Eijun was blue and Raichi was red, Eijun was calm, collected, and focused on doing well for his coach and team while Raichi was eager and focused on hitting the ball because he wanted the challenge rather than doing it for the team.
Sexy Spectacles: The female reporter from Baseball Kingdom admits to having a glasses fetish. She gushes over Miyuki, and acquires a Luminescent Blush when she observes the bespectacled pitcher from Akikawa Academy.
Shout-Out: In episode 45, Narumiya laughs going "Upupupu" and talks about instilling despair into Sakurazawa, clearly he is a fan of Monobear
Raichi's "Kahahaha" also qualifies as this.
Shrinking Violet: Haruichi is the shyest and least outgoing member on the team off the field, and surprisingly, Tanba was this during his first year.
Sibling Yin-Yang: Ryousuke and Haruichi; Haruichi is the shy, sweet, kind, and mellow younger brother in comparison to Ryousuke who is borderline sadistic, violent, and condescending at times; they also seem to have a Red Oni, Blue Oni kind of bond.
The Southpaw: This is a pretty big part of Sawamura's role in the series, apart from his sporadic pitching, the fact he's left-handed helps with his opportunity to join Seidou and is the only lefty pitcher Seidou has.
Also, Inashiro's ace, Narumiya Mei, is a southpaw and this along with his prodigious pitching helps solidify Inashiro as one of Seidou's main rivals.
Taught by Experience: Sawamura has no formal baseball training. Whatsoever. In fact, he hardly knows some of the basics of the game, but this lack of instruction actually helped him to develop a unique pitching style.
Took A Level In Jerk Ass: Furuya, after receiving the ace number his arrogance grew, and on more than one occasion thought, "I want the team to need me more."
Tournament Arc: Every team dreams with reaching Koushien. They have to win every match in the Preliminaries to get there.
Trying to Catch Me Fighting Dirty: During the Akikawa-Seidou game, Shunshin Yuu lures the umpire to call strike outs that otherwise would have been balls. He is able of doing this because of the perfect control he has over his pitches
