The best drama x sports manga (I've read 27 chapters so far, and no it's not an understatement)

Rating: 10.0 / 10.0

I don't even like baseball that much (dropped all the Adachi works) but this story is really good at setting up the tension, conflicts and distress felt by the characters. Tl;Dr it's about a story of a kid who tries to be happy but 'finding his place' or 'fitting in', but with extra baseball flavor.

Btw I'm of the opinion that baseball might be the only sport that could have worked. Any other sports wouldn't have the same potential in reaching the same peak. First of all, it has to be a team game where there are different roles. As the protagonist had a hard time when it comes to 1v1v1v1 or 1v1 games as he overshadowed everyone without the concept of collaboration. 2) a full on team game like soccer and basketball wouldn't have worked because es are way too important strategically. 3) in conclusion, it has to be a team game where a role shines so much and is so individually impactful that it can overshadow the other roles. No other sport than baseball can do this. You'll see why as you read this.

It's starts as an emotional journey of a 5th grader that examines the protagonist's talent as a dilemma (a talent being a curse), while showcasing how the surrounding characters react in a rational but emotionally driven manner towards his genius' imposiveness. I especially like how the coaches are being portrayed, conflicted but know that they have to treat such a child with sensitivity. But they are not just good people and having such a talent in their hands showcases an exploitative side to them. Where the child is seen more as an asset above all. I enjoyed this perspective.

Even if I knew nothing about baseball, it was still fun to follow (reminds me of Yowamushi on that respect as the cast was fun even though I knew jack about the technical aspects of cycling)

It's harsh and frustrating at times but at least the characters are conveyed in a realistic and understandable manner.

The way characters with different convictions clash and have to face each others is nicely depicted.

You'll like this if you can relate to the concept of competitiveness, team dynamics, coming of age introspection of a child growing up forcing to adapt to changes in environment outside of his control. The protagonist is also a really good kid, think of Iruma but thrusted in a much more melodramatic world. A lot of emotional maturity. It handles them well like 'Sensitive Boy' but of course with the theme being competitive sports and not SA fallout.

It got also a nice diverse cast of characters who react to the protagonist differently to his talent, most conflicted, but each deal with it in a different way. Some resort to aggression, while others try to be understanding, etc.

Compared to other sports manga, I think that it blends well the technical part, action part, and the drama part in a balanced way like 1:1:1. The drama is also natural and realistic doesn't overshadow the other fun part of the sport. Really finely threaded balance.

In comparison, I would rate some other sport mangas with this system like this:

Yowamushi was a 1:1:1 SoL Action Comedy.

Blue Lock would be a 1:1:1 Action Drama SUPERPOWER_NAMES_AND_FORCEFIELD (I call that 'shounen moment'.

Baby Steps would be a 1:2 Romance Technical.

Haikyuu would be 2:1 Drama Action.

Blue Box would be 2:1 Romance Drama.

Eyeshield 21 would be 1:1 Comedy Action.

It's not as intense as Blue Lock, but not as chill as Blue Box. It has that strange cold feeling of making you feel insecure and nervous when you partake in a sports event, or and competitive event. But sometimes it can get really exhilarating. And I like it because it's such a rare moment. Hence, in of vibes, I would say that this baseball manga would be closer to Blue Period (even though it has nothing to do with sports much less baseball) due to the introspective vibes and the chilling moments. Also the protagonist got a circumstance that's pretty close to Legosi (good boi who is always subjected to external pressures and expectations) but his personality is like Iruma (carefree and good nature, but in a soul crushing world)
