Kind of difficult to tell what's going on in the action scenes, of which there are many, and there's really not a whole lot of character development ... but I'm curious enough about the world to continue.

ASHIDAKA, The Iron Hero is your typical shounen manga with a kid with incredible power and a kind heart ready to save the world and bring tne best out of every person that comes in contact with him.

The volume one basically introduces us to the world Ashidaka lives in, it's a kind of post-apocalyptic steampunk world where people is born with a pair of mechanical arms that they have to keep maintenance with scraps of other robots that are in the wilderness. However, according to old scripts (the bible) people born with more than one pair are demonic humans that must die. Ashidaka and his adopted father Geji are those type of abhorrent four-mecha-armed humans that have to live in the peripheries of the city hunting for robotic parts of trash-bots to survive. One day the city gets attacked by an earthquake in the form of a robotic centipede and Ashidaka goes over there to kill the monster but faces a terrible realization: that monster is the bearer of the upcoming armageddon.

Then Ashidaka urges Geji to hunt dow that big centipede to avenge the damage it did to the city and this is how their big journey begins. They meet a group of four armed people that live in a hidden community protected by an ex-guardian that used to fight the big centipedes. His mission is the same but with the lack of an army he cannot do much. So Ashidaka eagerly joins this group and together keep on the path to stop the monsters.

Art wise it's pretty cool, sometimes it's a big of difficult to understand what's going on with the arms and the robots but you get the gist. I like the design of the characters as well, Ryo Sumiyoshi makes every single one pretty distinctive with different body shape, accesories and arm design. I like how every person has a type of arms that are adecuate for an specific function or fight style. Personally, Honchi is my fav guy. As a shounen manga, there's no big development on the characters because this is aiming for a long run, it's entertaining nonetheless.

Why did you read this book?
This is a manga I purchased a while back on sale because it had great artwork.

What format did you read this book in?
Read it as an eBook on Kindle.

Is this an educational book or a book for entertainment?
I read this book for pure entertainment purposes.

What genres do you think this book belongs to?
Fantasy, Manga, Science Fiction, Young Adult

What was your favorite part of the book?
If I had to pick a scene, it would have to be when there is a flash back and it’s revealed the MC’s mother didn’t abandon him willingly.

Who would you suggest this book to?
I would only suggest this book to anyone who likes typical shonen manga tropes.
Are there any cliché scenes or concepts? (If yes, does the author add something unique to them?)
All the typical shonen tropes are prevalent in this book. Protagonist is an outcast, he is born special, he has a mentor/rival, there is a big baddie to fight, there is a bad organization that wants to get in his way, his parent is killed. The only thing the author add was to place this in a “metal punk” type world.


What style of graphic novel is this?
It’s in the Japanese manga style (you need to read the book from right to left).

Is the comic colored, or is it in black and white?
This comic is in a B&W tone.


What is your opinion on the artwork?
Some of the are scenes were stylized and stunning, but the there were several that had too much going on with out any clear outlines to tell exactly what I was looking at.


How is the typesetting? Is the comic easy to read?
The fonts were great, and it was easy to read.

Is this comic a part of a series?
Yes, and I won’t be continuing to read it.

What is your general opinion/ rating of this book?
I did not like this manga. The pacing was too quick at times, the action scenes were too cluttered, and the storyline was too typical for its genre. The one thing I did like was the unique “metal punk” aspect of the novel. (If metal punk isn’t a thing, then the closest genre this fantasy world could fit into is diesel-punk.) The whole idea of a world where people are born with arm joints so they can attach extra metal appendages was different enough to get me interested in the novel. However, the execution of the concept didn’t appeal to me. I think the biggest issue I had with the book (besides the material being too young for my tastes) was the pacing. Things seem to jump from one scene to another with little transition or explanation. Overall, if you like the shonen genre, then you might like this book. But if you’re looking for a unique action pact world, then several other stories do this better.

Any trigger warnings?

I’m worried that this is going to turn into another typical “chosen one” shounen narrative, but I’ll stick along for the ride.

Also, as another reader has pointed out, sometimes the action is difficult to parse because of the way it’s drawn. Given that the action involves these uniquely designed multi-armed people, their movement can be lost in translation.

The world-building is sparse. Hopefully, it’ll become more realized as the story progresses.

Excellent, quoi que les scènes d'actions sont un peu lisibles et maîtrisées que dans son autre manga, Centaure. Également, ce tome est très dense en actions et n'introduit pas aussi bien le lore, les personnages, que Centaure. Mais la construction du récit semble volontairement différente, et probablement plus linéaire au fil des tomes. J'ai très hâte de le continuer.
