It did feel kind of unimpactful how it finally revealed that the masked person from the first chapter was Micardo, which was such a mystery that was very casually resolved but other than that the story feels extremely planned with the initial lines from the first chapter about it being a violation of the rules being clearly planted to allow for this.
I've been reading some other works by this artist in the meanwhile that aren't translated and this artist really knows how to write a well planned mystery. They're typically about three volumes in length and every time it felt like the entire story must have been planned from the start so I have high hopes.
