Really fun system! I was looking for solo RPGs to do to calm down during a move, and I found this one. The culprit of my first case, who gave a kid named Okawa a headache and splashed water on him while he was going to school, was a cat named Tsume who kicked his water bowl out a window, which landed on Okawa's head. The mysterious child singing in the alleyway that students would hear going to school was nothing but Tsume's automatic food bowl refilling.
