Ragna Crimson is an amazing manga, I never wrote a review before even though I've seen lots anime/manga, but felt I had to due to how great this manga is but sadly doesn't have that many readers. [I'll try my hardest not to spoil]
Story-9
The story at first seemed pretty normal with the cliche main character is weak and wants to get stronger to beat the bad guys and protect his friends. In the first chapter however that idea completely changes and the manga starts its own unique path. The main character basically ends up getting some powerup but it comes with a price- his body isn't adjusted enough to properly use it. The story is interesting and way better than most, I can't say much since currently theirs only about 16 translated chapters and I don't want to spoil such a great story in any way.
Art-10
The art would clearly be an easy 10, most of the time the arts a 9.5 being much nicer and beautiful than other manga, but than every few pages, it shows a beautiful carefully made work of art that I would give 12/10 if I could.
Character-7
Theirs only 2 main characters being Ragna and Crimson [As the manga name suggests] with some side characters who serve crimson, the side characters are pretty simple but still have their good qualities- cant be well explained due to only being around for like 4 chapters.
Ragnas pretty shy but knows when its time to fight and wont hesitate the slightest bit. Ragnas thoughts and reasons for fighting are clearly and nicely shown when he has to make a choice that will either protect or hurt the one he holds dear.
Crimson is just crazy it looks like he/she is crazy and will do whatever it takes to accomplish her goal of killing ALL DRAGONS.
Enjoyment/Overall-10
Absolutely amazing, I don't see a single problem with this manga besides the low amount of chapters, I was both surprised and disappointed when I saw how low the readers were on this, I can't believe how lucky I am to have just found this manga. I hope you also read and enjoy it.
