The stories they investigate are always well structured and are developed at a good pace, setting the anime apart from others in the investigative genre. The main characters, at least in this first season, didn't get much depth, so it's kind of complicated to comment on their design, but it's easy to say that they are all at least interesting. It's cool to comment that the series is a spin-off of the television series Kamen Rider, which is a Japanese media classic. I really liked the style of animation they delivered, as it was well done and synthesized the overall content of the anime very well.
