This is a very good anime that focuses on dealing with a lot of issues. everything has a deeper meaning to it for example those mysterious tools are probably referring to solutions that work in the short term but not in the long run and instead of looking for quick fixes we must try and solve the problem from its root. Every disease is due to a certain event that has left the person psychologically distressed or disturbed . I can see why some people might have an issue with the anime but I would say it is a pretty good anime . It has botha fun and easy going theme along with a dark and heavy theme at times. So overall I would say if you are looking for a good 12 episode psychological genre anime to watch , go for it .
