This is an interesting story for sure. It just has one of those very common problems. Instead of following the main storyline, the one we're all interested in, it keeps having episodic mysteries where the same thing happens again and again. Nothing changes between the dynamics of these characters. And the mysteries are not that great for me to ignore this flaw.
Nonetheless, it's a fun enough time for me not to drop it. Ron is a fun character. The world building is interesting. And I'm looking forward to seeing what the main plotline holds in the future.
Mainly, who I wasn't fond of was the side character - Totomaru. He's just not good enough honestly. Just being a good person doesn't make a character. He doesn't change across the mysteries. He acts the exact same way again and again. I would've liked to see some sort of strength or resolve from him. Or I would've liked to see him learn from Ron as he solves these cases. Or, if not that, at least improve upon the main purpose he's there for. He accompanies Ron for a reason. Without spoiling, I'll say that he's there to save people from dying. After 3-4 cases he should know that he needs to save this person and try something different as soon as possible. But no, he just keeps standing there. Until whatever's going to happen, starts. And then he'll rush to save the person at the last moment. It's not good character writing.
But anyway, Ron and the now formed villain in the main plotline, are interesting enough for me to look forward to season 2. But this was a mediocre experience.
