The 'mystery' genre brought my attention to this anime. It has no genre in extremes. All the genres like Comedy, Mystery, School, Sci-Fi, Psychological, Supernatural, and Shounen are in an equal mixture, which makes this anime special. Even though the diseases mentioned are not real-like, the cause of the disease shows the different kinds of psychological mindset or pressure a person in real life can have. Every episode will make you laugh as well and to wait for the next episode. The 'standing out from other anime' thing is the sound. The mixture of violin, guitar, etc are the best. I really recommend this for the people who likePsychological and Mystery genre.
