I really love this anime. Characters are unique in their ways. The story is fun and it is rare for this kind of genre. There is also a lot of knowledge inserted throughout the story and you can apply that knowledge in your real life. The art & sound are not top-tier anime but the quality does not drop throughout part 1 and part 2. The story and character can compensate for art & music. I really wish it will have season 2 (now it is only season 1 part 1 & 2. If you have never watched this anime before, I strongly recommend totry once. Let's support this anime together :)
