I hear a lot of people criticizing the art, but, its rough style really gives the rustic and raw feeling that stories of adventure guilds (like monster hunter) have. It's also a refreshing style compared to the mass of manga drawn on computer and edited to be perfectly clean.
The plot is decent, but, there needs to be more focus on building the characters. They are flat, except, maybe the traitor father. However, this manga is also one of the few that actually focus on the adventurer relationship. Most mangas do not have the mc interacting with the adventurer guild. The characters also quickly recognize a hunter potential instead of other mangas where the mc is berated as a newbie.
Overall: 7/10. Recommend?: 7/10
