At time of review, I've seen 8/12 episodes, but I need to get my thoughts out.
When I first heard of this anime, I couldn't help but laugh at the concept. I really haven't paid any mind to the guild receptionists of other anime, so this is a really interesting spin on the fantasy anime genre. The show does try to work its concept to the fullest, and I think it mostly succeeds. It's hilarious, and Alina is a really fun protagonist who, in my opinion, has some decent motivation for living the life she's trying to live. Her relationship with the love interest is a lot of fun and these two carry the show.
Unfortunately, this show does still have a lot of flaws. Most other characters feel weaker/underdeveloped so that the show can focus on Alina and Jade (and Lululee to a surprising amount). The red haired guy in the adventuring party who I can't even remember the name of especially suffers. In fact, I think I've seen him use only a single spell the entire show. Frankly, he may be one of the most useless anime characters ever. The animation itself isn't fantastic, especially in action scenes, except when Alina is doing some of her big OHKO moves and the monster dies. (The anime industry is known for overworking the artists, so I'm laying blame with the studio and not the artists themselves).
I will be finishing this anime, as I enjoy watching Alina and Jade, but it is really hard to recommend this to many people.
