Diamond no Ace

With a stray pitch that completely missed the batter, Eijun Sawamura loses his final middle school baseball game. Frustrated by this defeat, Eijun and his teammates vow to reach the national tournament once they are in high school. But everything changes when a scout unexpectedly invites him to Tokyo's prestigious Seidou High School after seeing the potential in his unusual pitching style. Encouraged by his teammates, Eijun accepts the offer, ready to improve his skills and play at a much more competitive level of baseball.

However, now surrounded by a large number of skilled players, Eijun struggles to find his place on the team. He declares that he will one day become the team's ace, but that's only if fellow first year Satoru Furuya doesn't take the title first, with his breakneck fastballs that earn him a coveted spot on the starting roster. With the addition of these talented new players to an already powerful lineup, the Seidou baseball team aims to become the best in Japan, facing off against a number of formidable foes that stand in their way.

I recommend this anime to sports fans. Honestly, the pacing is slow, so it might not be for those who get bored easily. However, for patient viewers who appreciate storytelling, this could be a great addition to your watchlist. For sports anime fans, it won't disappoint. The genre's usual team sports theme shines through, with deep emotions, strong determination, ambition, and exceptional skills. The strong opposing teams make me excited and curious. What I love about sports anime is the suspense of facing new opponents. The MC stands out with a unique personality, and their skill and humor had me laughing and invested in the ... story. Give it a try if you're curious! ^_^

Mixed Feelings

This show has a very strong and engaging start. The introduction to the characters are nicely done, the premise is interesting. I like that it wasn't going to be an "underdog" story. I feel like the first 20ish episodes is where the anime truly shines after that it kind of goes downhill for me. The show was really good at setting up a goal for Sawamura and the team. Watching how they achive that goal was exciting and mostly rewarding. My favourite part was the Chris storyline and how Sawamura learns from his mistake and grows as a character.
On the other hand I think ... the show fails at creating a well-rounded rival for our main character. I hated Furuya. This kind of rivalry is hard to done well. You want this character to be somewhat threatoning yet loveable - and I feel like DnA fails at that. They put so much more on the threatoning part. Furuya starts of as lonely, somewhat shy, introvert, yet proud "monster" pitcher. Which is fine... Not too original but could've been done well. His personality is polar opposite to Sawamura's. It should've worked magnificently. Haikyuu had done it well with Kageyama and Hinata. I think the main issue with his character is that we see and know so little about him. Yes, we know his a "monster" but what else? Him being a prodigy is not his personality. Yes, we see him warm up to the others but he doesn't really creat any meaningful bonds with them, he's just there. I would've loved to see him talking about his past, how it effected him not having friends and being rejacted. Confiding in Miyuki maybe.
Overall, I enjoyed watching it for the most part. The games were exciting, but they also get more and more frustrating.

Diamond no Ace is an anime from 2013-2015 based on a Terajima Yuki manga. The anime was handled by Production IG and Madhouse. I'm not expecting much since it's a sport anime but it was a request so, let's get into it.

Story:

We open with our main protagonist, Sawamura Eijun, being recruited by Seidou, a school with a proud tradition of throwing balls and hitting them with sticks. He sets his sight on becoming the lead pitcher and getting the coveted "Ace number." From there, the anime follows Seidou's performance in a big tournament and the aftermath.

Let's start with the main problem that really makes ... this series kind of unbearable. The pacing is horrendously slow. The longer games take longer than the card games in Duel Monsters and at least those have holographic monsters attacking each other. In these, we have a lot of the same thing with the pitchers throwing balls and the plays that follow and long, drawn out stretches of the crowd reacting. So, we have slow games, slow crowd reactions & slow training sequences. This series is actually so goddamn tedious and boring that you either have to let your mind wander and think about other things or you'll enter a catatonic state. If this is accurate to watching Baseball, it's no wonder the game basically ceased to exist in the Star Trek universe and had to be radically altered to be more interesting in Futurama.

Here's another huge problem I have with this series. It's set up so that we, as the audience, are supposed to be rooting for Sawamura and we're supposed to see him as a pitcher with amazing potential. But he comes across as a rubbish player. He can't control where his pitches go for shit. He's constantly breaking down at crucial moments, screwing the team over and having to be coddled to regain his ability to pitch. Maybe it's just because I don't know much about Baseball, but to me those seem like really horrible qualities for a player. Like, this person would never actually make a competitive team unless they got their shit together.
On the positive side, at least this series doesn't go the usual sports media route of following a group of plucky underdogs. Instead, we have a highly skilled team plus Sawamura and the tension comes from there being a lot of other highly skilled teams that are on their level or a bit above.

Characters:

The big issue with the characters in this is that they're all kind of similar. In the sense that they're all obsessed with baseball. Aside from that, there's not that much to their characters. Sawamura is the energetic protagonist who tries hard but has to overcome his own inadequacy. The coach is the understanding but strict mentor figure. Chris is the calm and collected upperclassman. I'm going to stop with those three examples because this anime has thirty million characters.

The anime also has very weak character interactions and relationships. We see them play together and train together but we very rarely see them talk about anything besides baseball or spend time doing things unrelated to their training or playing the game. Which just contributes to the sense that these guys are all overly obsessed with this tedious game that doesn't matter. I mean, is it normal to cry like a baby when you lose a game?

Art:

The art looks fine. I couldn't tell you if the character movements or pitching forms are accurate to baseball but they move smoothly enough. If I were to bring up any issue, it would be that a lot of the character designs are kind of similar and they basically largely consist of generic looking guys. There's a point where Seidou's old opponents are watching them play a game and it took me multiple episodes to remember who they are and even then it was largely because I was wondering why they kept cutting to these random people.

Sound:

The acting is passable. Mayhaps a bit exaggerated at times but it largely sounds fine. The music is mostly fine. The biggest problem with it is that they constantly play the same music whenever there's a "pinch" or triumphant moment and, in an anime this long, it just feels stale after a while.

Ho-yay:

Maybe if the characters had stronger interactions we would see some that came across as a bit ho-yayriffic. But since the character relationships are generally weak and built around taking a game far too seriously, that doesn't happen.

Areas of Improvement:

1. It would help to show the characters in more diverse situations. Not only could the relationship dynamics be stronger but it could also help flesh them out as characters in general.

2. Speed things up. We don't need ten minutes of crowd reactions for every "big play" and we don't need long pauses between plays. There is a degree of that that can help increase the tension but this anime takes that degree and multiplies it tenfold.

3. Sawamura shouldn't be as rubbish as he is. I understand what Terajima is going for. He wants to follow Sawamura's journey and show him overcoming adversity. I'm sure in series twenty of this he'll actually be amazing. The problem is that he makes him too bad considering he's on Seidou's main team.

Final Thoughts:

If you're a huge baseball fan and you really want something to watch when there aren't any actual baseball games on, this might just be the anime for you. For everyone else, it's far too slow and dull for me to recommend it. And I'm giving it a 3/10 because it's that much of a slog.
