The main girl(s) isn't annoying at all. She's extremely strong, very sweet and doesn't act out for no reason, but expresses her opinions openly. She has a very good relationship with MC. (Platonic).
The premise is a fantasy/video game mashup but the story is executed realistically. The art is pleasant and doesn't distract from the story.
Overall the story, characters, and art are very compatible, and the premise is interesting and actually adds to the overall enjoyment, despite how frequently it's used in seinen and shounen.
One thing that could be said is that the story's representation of magic seems a bit silly sometimes. It seems like magic can solve basically any problem if you have enough money, and the all-encompassing power, convenient faultlessness, and ease of access to magic in the story is a bit excessive.
You would think the shameless incorporation of video game styles would take from the medieval themed manga but it doesn't. Actually the shamelessness saves it, having the characters themselves draw similarities between video games and the world, and the manga not trying to be subtle at all about the leveling system.
