While the series focuses on a reality equivalent to others, it gives you a chill of suspense that something out of the ordinary will happen. This is constantly reflected on the fact that the antagonist of the story is continuously causing horrific crimes yet police officers around the world refuse to believe his existence even when his name is repeated several times.
The antagonist is perhaps my favorite character due to his ability to elude the police, his intelligence that surpasses anyone in the story and even how he acts. On the outside, he is charismatic and looks like a good person, but by that time, the audience knows he is a mysterious monster lurking with plans in store that no one can comprehend.
I cannot say much about him due to being spoilers, but if you want to watch the anime just for this character, feel free to do so. He is essentially the one that weaves the story throughout.
