Not for me. Too much panels of characters faces and dialogue. Not enough scenery. Plot just sort of happens and we're expected to accept it even though the author didn't endear us to the characters. Why should I care?

Ragna Crimson Review

2/5 stars

This will be a spoiler free review. Onto the review!

I read three volumes of this manga and stopped there because I really did not like it that much. The basic premise is that there are these dragons who are attacking the human planet where our main character is from. The main character, Ragna, is a warrior who fights dragons to try and drive them off of his planet. (Side note: all dragons in this series have both a dragon form and a human-like form)

We learn pretty quickly that the dragons aren't just attacking this planet for no reason. They serve a god that rules over the entire universe. This god has an image in their mind of what the universe should look like, and it doesn't match the way the universe is now. If something needs to be created to fit the god's vision, the dragons have to find a way to make that thing. If something needs removed, the dragons have to destroy it. The human planet Ragna lives on is one of the things that does not exist in the god's view, so the dragons are tasked with killing all the humans.

I was really intrigued by that concept. It sounded really cool. But unfortunately, this series just wasn't working for me. Most of the drawings were of the characters against a white background. I went through one of the volumes I read to try and figure out how many drawings of the background there was, and I counted six. I have no idea where these people and dragons were, or what was around them, aside from being told in dialogue that they were in a city.

I couldn't get immersed in the world because I don't know what the world looks like. We only ever got one or two images of the crowd in this city, despite there being many scenes that supposedly take place amongst the crowd. Where were all the people? Why was it just a blank white background most of the time?

In addition to that, we were introduced to a whole bunch of dragons with all different kinds of magical powers right away. We don't get to discover them over time. They're all just lined up next to each other, with boxes explaining who they are and what they do. It felt like the author was trying to create more new character designs for the fun of it, but then didn't want to take a whole lot of time to give them all backstory.

That aspect of the story reminded me a lot of when I read My Hero Academia about five years ago. Too many characters got introduced, and none of them were really explained. In contrast, my first ever manga, Naruto, had a lot of characters and every single one of them got a really detailed backstory. I wish this was more like Naruto in that regard, because it made me not care about any of these people and dragons.

There was also something going on in regards to time travel that hadn't quite been fully explained yet. I got the feeling in the first volume that this would be something to explore later, but as I went on, it never got explained. And then more time travel stuff kept happening with little to no explanation. This made me very lost and confused to the point where I no longer cared that much about the plot. I'm pretty sure it would have eventually made sense if I kept reading, but I really didn't care to get to that point.

Also, apparently an anime came out last year for this series. I might give the first episode a try in case the anime is better than the manga. Maybe the anime fixes some of the things I didn't like about the manga.

I think if you like manga like My Hero Academia or Demon Slayer where it's all about the action and cool characters, but character development is left a little bare, you'll probably enjoy this series. But sadly, I did not have a good time with it and will not be continuing.

Have a nice day/night everyone!

With a number of successful hunts to bolster their confidence, Ragna and Crimson aim for their biggest prey yet: Ultimatia. Although Ragna's powers are great, how will he tackle a dragon that can manipulate time? Nor is Ultimatia the only dragon within the city walls . . .

These always feel like half-novels despite later fight scenes that have barely any dialogue. Despite the length, this one doesn't make it through the current arc and ends mid-fight.

Much of the early pages are setting up two of Crimson's subordinates, as well as the various dragons and their powers. Ultimatia's kindness in some ways makes her a worse villain than even the Tempest Dragon, because she's all for making everyone die happy. Chimera and Golem can be fun, though, especially when they're picking on each other.

If I have one main complaint it's that Crimson spends most of the time lurking in the background doing little more than scolding her subordinates. There are small hints of plots, but nothing visible, and then Ragna kind of does his own thing anyway.

Overall this was okay. If you liked the previous two volumes this is worth a read. I rate this book Recommended.

⊹ 4/5 ⊹

un troisième tome riche en combats et qui fait avancer l’histoire ! j’ai adoré en apprendre plus sur Altémacia (tellement adorable qu’on a du mal à croire que ce perso est cruel) et rencontrer les acolytes de Crimson (gros cœur sur Chimère 🐈‍⬛) ! encore un quasi sans faute pour moi, et j’ai hâte de continuer cette saga 👀

Witnessing the kindness of the first dragon is my favorite part. Her being this beautiful angel\dragon and slaying all these humans makes her a great villain. I love the fast pace this story takes and it's definitely a thrilling one. I'm more than glad I got it.

It's a set up book, I get it. I really struggled to care with the plot and characters.
Also, ending the book mid-fight to sell the next volume frustrates me so much.
Just not for me.
