**Don't judge the beginning. The author was stupid and felt a need to get readers through fan service. **
If this is your first look at Ubel Blatt and you're unsure as to whether to read it, I recommend that you do. The 200 votes for a 10 is not a lie. This is a captivating story with a variety of characters on opposite sides and good art also—which includes cute female characters. I'm warning you in the beginning the mangaka seemed to tried to get viewers through fan service for whatever reason. There are some ludicrous moments in the beginning but it phases out as the author ushers in a captivating story.
If this is your first perusal at the manga, don't judge it by it's cover picture with an elf. I assure you that not everyone is an angry-looking elf. This manga is one of those fantasy mangas with multiple races. To my knowledge,the sentient ones are elves and humans. The world of Ubel Blatt is set in a medieval-esque world (so that means swords, castles, arrows, ect) but also with magic and fantasy. There are dragons and griffin-like beasts—which can be used as steeds—, magic wielders, and also magic-based technology reminiscent of early modern tech which are blimps and giant-laser-canons-of-doom-that-resembles-a-giant-mounted-serrated-knife. There are at least two empires in the Ubel Blatt world, one with a sinister-looking culture (summoning, employs scary-looking beasts) and the other that is more righteous in appearance (no scary summoning/beasts). Whether or not one is evil is impossible to tell for sure as the story is set in the righteous-looking country. The other country is only referenced when quoting history and as of yet has no connection with the plot except for stuff that happened in the past.
Ubel Blatt is told from the viewpoint of Koinzell who goes against the empire. In the eyes of the people he is evil. However, you'll find that there's some truth behind his goal. It is an adventure so the main character travels with a group of friends. All of them are people who he's helped and are devoted to his cause not b/c of their debt. However, the story does not only center on Koinzell and friends but seems to be branching another viewpoint—which won't be spoiled here. Koizel is still the main lead however.
The main character possesses great powers but so do some other people (officers in the army). This isn't like Dragon Ball Z where there is a huge power disparity. A contingent of troops actually has a chance (depending on the tactic) against an officer. It is, however, a small chance against the more elite.
There's a chance that Ubel Blatt is heading towards a romance. If it does, the romance will remain as a side story along the main quest. I do hope it does however.
You must've been really intrigued to read through all so instead of delaying it, pick up a volume and start reading!
I give this a 9 b/c it's unfinished
